Amendments to the sign ordinance were adopted first, becoming effective in November 1997. The park dedication ordinance was the next topic addressed, and this new ordinance is currently being reviewed by City Council. The landscape regulations are next on the schedule for review and revision. The current ordinance has been cited as confusing in some areas, difficult to enforce, in need of heightened attention to tree preservation, and in need of increased planting requirements. Staff has undertaken a relatively new approach to landscape requirements, focusing on the city's "Urban Forest" instead of individual tree stems. As a result, a draft landscape ordinance has been prepared that would replace the current ordinance in its entirely, rather than amending + existing requirements. The major principles involved include (1) the required designation of the "Limits of Clearing and Grading" that would prohibit mass silo grading and clear-rutting, and (2) the "20/20 Rule", which requires a minimum of 20 trees per acre and 200/9 of site area dedicated as planting area. These arc major changes, but are comparable to other cities' ordinances. The ordinance is also relatively brief in an effort to make the regulations understandable, and easily administered and enforced. The draft has been titled as an "Interim" ordinance because further changes are anticipated %4-ben street tree requirements are added. Street tree requirements have been temporarily postponed until a right-of-way strategy can be developed as part of the " comprehensive plan + ESTIMATED SCHEDULE OF PROJECT One City Council Work Session has been scheduled for this item, on February 10r°. A public hearing is scheduled for February 17'h, If approved on February 17'1', the effective date of the ordinance would be on or around March 4",1998. i PRIOR ACTION/ EVI % A public meeting was held to discuss potential revisions to the current landscape ordinance on , • 40 December i l'% 1997. A summary of meeting comments was included in one of the two packets of review materials recently delivered to City Council members and P&Z Commissioners. The City Planning and Zoning Commission conducted a Work Session on this item on January 10, i i I 75 ,K 32x O 1998, and held a public hearing on January 2e, 1998. The P&Z recommended approval of the basic format of the ordinance by a vole of S - 2. P&Z Commissioners also asked that several 1 issues identified during the public hearing be forwarded to City Council for further discussion and deliberations. The draft landscape ordinance will be placed on the February l 1°,1998 P&Z agenda as a discussion item to determine if additional comments will be offered in time for the February 17`h City Council public hearing. I ISCAL INFORMATION The draft ordinance will affect all unpiatted and undeveloped land located within the City of Denton, and will Impose plan preparation, plan review, and tree and landscape installation costs as part of project development costs. City-owned property will also be subject to the ordinance as proposed. Ordinance administration and enforcement costs will be bome by existing personnel, and will impact the operations of the Development Review Committee (DRC) and Inspections and Code Enforcement staff members. The Engineering Department has indicated that city subdivision regulations and drainage manuals will require modification if the clearing and grading requirements contained in the draft ordinance are adopted.

Q a I I_l • o i 1 AGENDA INFORMATION SKEET AGENDA DATE: February30'",1998 DEPARTMENT: Planning & Development I CM/DCM/ACM,, Rick Svebla SUBJECT Receive a report, hold it discussion, and give staff direction regarding a proposed landscape ordinance. BACKGROUND City Council his instructed staff to proceed with the implementation of several regulatory projects related to Denton's development codes. Amendments to the sign ordinance were adopted first, becoming effective in November 1997. The park dedication ordinance was the next topic addressed, and this new ordinance is currently being reviewed by City Council. The landscape regulations are next on the schedule for review and revision. The current ordinance has been cited as confusing in some areas, difficult to enforce, in need of heightened attention to tree preservation, and in need of increased planting requirements. Staff has undertaken a relatively new approach to landscape requirements, focusing on the city's "Urban Forest" instead of individual tree stems. As a result, a draft landscape ordinance has been prepared that would replace the current ordinance in its entirety, rather than amending existing requirements. The major principles involved include (1) the required designation of the "Limits of Clearing and Grading" that would prohibit mass site grading and clear-cutting, and (2) the "20/20 Rule", which requires a minimum of 20 trees per acre and 1101/6 of site area dedicated as planting area. These are major changes, but are comparable to other cities' ordinances. The ordinance is also relatively brief in an effort to make the regulations understandable, and easily administered and enforced, The draft has been titled as an "Interim" ordinance because further changes are anticipated when street tree requirements are added. Street tree requirements have been temporarily postponed until a right-of-way strategy can be developed as part of the " comprehensive plan. 0 FSTISIATED SCHEDULE OF PROJECT One City Council Work Session has been scheduled for this item, on February 10". A public hearing is scheduled for February 17'". If approved on February 17'", the effective date of the ordinance would be on or around March 0, 1998. PRIOR ACTION/REVIEl4' • A public meeting was held to discuss potential revisions to the current landscape ordinance on ! • December 11'% 1997. A summary of meeting comments was included in one of the two packets of review materials recently delivered to City Council members and P&Z Commissioners. The City Planning and Zoning Commission conducted a Work Session on this item on January 14'", 32 X I Q 1998, and held a public hearing on January 280i,1998, The P&Z recommended app: oval of the l basic format of the ordinance by a tote of 5 - 2. PH Commissioners also asked that several issues identified during the public hearing be forwarded to City Council for further discussion and deliberations. The draft landsetpe ordinance will be placed on the February I V% 1998 P&Z agenda as a discussion item to determine if additional comments will be offered In time for the February 170i City Council public hearing. FISCAL INFORMATION The draft ordinance will affect all unplatted and undeveloped land located within the City of Denton, and grill Impose plan preparation, plan review, and tree and landscape installation costs as part of project development costs. City-owned property will also be subject to the ordinance as proposed. Ordinance administration and enforcement costs will be bome by existing personnel, and will impact the operations of the Development Review Committee (DRC) and Inspections and Code Enforcement staff members. The Engineering Department has indicated that city subdivision regulations and drainage manuals will require mod;fication if the clearing and grading requirements contained In the draft ordinance are adopted. EXHIBITS Thin memorandum is part of the "Interim Landscape Ordinance" booklet that has been prepared for City Council. The booklet contains a copy of the Draft Interim Landscape Ordinance, P&Z revitiv comments, and other review materials. The Plaruung and Development Department staff Mll provide any additional information as requested. 1 Respectfully Submitt Bill pa'Kd M.

C Mr, David Hill presented the staff report. M nth x 10 32XIO i 0 A n ' a~:swts Planning and Zoning Minutes January 28, 1998 Page 2 1 Mr. Hill: Thank you, Madam Chair, and members of Commission. First of all, hopefully you all have copies of this ordinance, and the first thing 1 would like to start with is to apologize for the late arrival of this. We hand-delivered this on Tuesday, and the only comment that I have to make is that we went through several iterations at the staff level. 1 think that we found that there were a lot of complexities that we felt that we needed to address. I'm not sure that we have taken care of this exactly the way we'd like, even from a staff level. We know that there is room for 'improvement in here, and we are just ready to see what kind of public comments you receive and be prepared to even make some further refinements as this goes to the City Council. So, I think we recognize that this is not something, for example, where you have a sign ordinance where you are simply talking about prohibition of signs-that's kind of a y&no question. This one-you are talking about the different kind of land usage and the different applications of vegetation that things look simple from the outset; then all of a sudden, you get Into the complexities of the inner relationships of the usage of the plant material. The one thing I would like to start with- and 1 think you will notice that this may be one of the thinnest ordinances you will have-so what we've lost in time for review, maybe we have made up in brevity. If you take away the first two or three pages that contain the purposes and the definitions and the last page, which happens to be the plant list, we really have about four or five pages of regulations. And one of the things that we stated that we wanted to do from the outset was that we wanted to simplify the regulations, So 1 think we did that. I also think that we responded pretty closely to the outline format that we showed you at the work session. I'll be happy to answer your questions. 1 would like to suggest the format for this if you don't mind, Madam Chair, Chairperson Schenz: Please. Mr. Hill: You tell me if you would like to do it this way. Nancy McBeth has prepared some research documentation. I'd like maybe to give her about 13 minutes to address some of the questions that you asked us to look into at the work session; and then, if you have some questions for me, that's fine-but maybe go ahead and go straight into the public hearing and see what kind of comments you have, and I'll be here to answer questions. So, would you like for us to address some of the questions that you had from the last work session? r Chairperson Schcrtz: Please. ♦ Mr, All: Okay. Nancy, why don't you do that, please. Ms. Nancy McBeth: (food evening. 1 would like first to pass out a couple of items • One is sonic information that 1 got from John Cooper from the Texas Agricultural Extension Service, Sts some additional plant list material, and as well, some more comments that we've gotten on the Landscape Ordinance. In your packets, you received a variety of exhibits. One of those Is ♦ the vegetation areas of Denton (Exhibit A). In that, we've tried to answer your questions about the two zones of vegetation that exist in the Denton city area. You'll see a little block that's been colored in right here, and there are two predominant zones, zones 3 and 4. This side is called the black land prairies' and this side, to the west, is the "cross timbers and prairies" section. With that exhibit, l have also included a list of vegetation from the same source that lists plants that are ?SwQ 32x • p amwa i Planning and Zoning Minutes January 28. 1998 Page 3 ti growing naturally in those areas, just by/through attrition and that will grow there if planted as well. And with that, as well, the list 1 just handed out from John Cooper's office is a really good resource for the first list, the two page list of naturally occurring vegetation, native vegetation and the second list is a good list of vegetation for ornamental and native planting as well. The next section that you had questions on regarded the soil delineation in Denton, This map up here is a soils map that Is moderately deep and deep soils on the upland savannahs, and this is Just the Denton city area, Let me see if 1 can get it more centered-there, As far as we can determine from the vegetative line you saw earlier that falls in Denton and the soils map that you we before you, that line probably does, indeed, run along 1-35, and the cross timbers prairies and the black land prairies fall on either side of that. The soil levels go from moderately deep and deep soils all the way through to deep soils on bottom lands where those areas indicated in green along riparian or waterways. Also Included in that package was a pretty comprehensive list of, and more detailed list of, what those soil levels are and what they will allow on a building and on a growability level for each one of those soil zones. Mr. hill: Our camera is not giving us the opportunity to show this. Ms. McBeth: Well, if you'll look In your Section E, Exhibits Pervious, which is the second chart "Tree and Lot Area Analysis." One of the questions that came up was the ratio of 20 trees per acre and what that relationship was on different lot sizes. So we've tried to give you a comparison of what that looked like and how many trees would have to be provided--plus how much open space for that type of lot would have to be provided. Its broken down into lot area for that type of lot, and I've also included non-current lot sizes because there was an Interest in "what if we had smaller lots other than in the code right now." So, there are some other lot sizes in here which include impervious cover area allowed (which is the building itself; any pavement areas, patios, porches, driveways, and so on) and the pervious area-the open space requirement at 20% and how much, what that looks like, and the quantity of trees allowed on that. You'll notice a differentiation between commercial sites, commerciallindustrial sites, and residential on this than and whet that impact would be, To give you an idea what that looks like, we've done a couple of sketches. These are residential lots, Two of the lots-the 10,000 square foot lot and the 7,000 square foot lot-are current code lots sizes that are fairly typical (7,000 square foot and 10,000 square foot), and then a non-typical lot at 4,000 square foot indicating what that ma.elmunt build-out would look like on the ground area using the coverage requirement for a • building, in particular, in residential, And the maximum impervious surface allowed and the quantity of trees that would be required for that lot size. So, you can pretty clearly see that that's not an abundance-an overabundance-of tree requirement for those lots, based on the size of the lots, Then I've taken a commercial site, this is just a typical office site, a one-acre site that has a two-story, structure on it, that's got 14,000 square feet. It's got setback limitations indicated, these are the normal setbacks right here. It's got a street on two sides, and it has two • areas where it's abutting a different use, In this case, I've indicated a landscape buffer; you can • • see what it looks like typically under the ordinance that we're proposing. I<1r, Hill: Could we ask for a zoom? There-thank you. / - ? xk~ 32 x~❑ • o Planning and Zoning Minutes January 26,1996 Page 4 Ms. McBeth: This would be the landscape buffer that was adjacent to a use that needed buffering. In this case, there is no buffer indicated; I made the assumption that this would be a like use next door to it. It also Indicates saved trees on here, They're In a darker green. 1 know it's hard to differentiate, but they're the larger trees here, here, and here that I've shown to be preserved trees on the site; and additional trees that' would be required to meet the 20-tree requirement on here. Because on this particular site, there's an indication of saved trees, they're getting credits for that. They are getting six trees credited that are 12 to 19 inches and seven trees credited that are 6 to 12 inches on here. And, under that six tree scenario-the bigger trees-they actually only have four trees, but they are getting credited for six because they are a larger tree, and seven new trees for a total of 20 trees on their site, This also Indicates the requirement that a tree be within 50 feet of every parking space. It Indicates screening around the durnpster and in particular its location. And it also indicates some of the shrubs being required. It also indicates screening required at the street here, here, that screened the parking lot from the street. This also Indicates another question people had at the last meeting about what if I we have some incentives for setbacks-if they threw the parking lot to the rear, they did some additional, they tried to save some preserved trees in certain areas-would we allow some flexibility there. So, what this Is indicating is a 10-foot reduction in setback along the building line only. It's also allowing a-because they're located to the rear and side of the structure- 10% reduction credit for tree preservation on the parking requirement. So there was, basically, 46 parking spaces that would have been required for the structure and 42 have been provided. Another question that was asked was where the definition of "urban forest' came from, what was that determination, and then its background. This information came from a planning advisory service publication called Tree Conservation Ordinances, and it is considered a "bible" for tree preservation across the United States. It is also used by the Texas Forest Service, and the definition of a forest is "a biologic community dominated by trees and other wooded plants covering a land area of 10,000 square feel or greater, Forests include areas that have at least 100 trees per acre with at least 50% of those trees having at least a 2-inch or greater diameter and 4Vs feet above the ground. The forest areas that have been cut but rot cleared," Further, when that information was taken, we have determined that (on a state-wide basis, from information provided by the State of Texas) that there Is one acre of tree cover for every $1 acres of land; M, that since this is a state-wide ratio of 7.2 trees per acre and since Denton County coverage is slightly higher than the slate average based on the vegetation areas of Texas as provided by the Texas Department of Agriculture-we conclude that a 206/9 ratio of the definition for forest of 20 trees per acre is appropriate as an Urban Forest coverage for Denton. Mr. Hill: One of things that I wanted to do for you quickly, and 1 think there is going to be some discussion about this during the public hearing-the soils map-if you take the approximate line as being 1.35 West and North 1.35 as the line of demarcation for the two ecologically separated r ecosystems-whatever you want to call them-the one thing that 1 wanted you to notice Is that gi the soil types do not necessarily follow that line; that some types, some of this yellow which Indicates more well drained soil, happens to be both on the west and east side of 1.35• And the best Information we could get-and maybe we will get some elaboration tonight--Is that, I think we were leading up to the question of, is It fair to expect trees to be planted; will they survive In - - - ~~w~ r, 0 32X10 G ~ 1 Planning and Zoning Minutes January28,1998 Page S l the grass lands with the prairie portion of the City of Denton? And the answer that I think that we received was that there is no reason to believe that the trees would not survive with a ' preference that there be some soil amendments and water being provided, But that those would not be absolutely necessary to the survival of the tree, because obviously there are trees over on that side. And, i think Commissioner Powell even asked about that specifically. I think there will be some more discussion about that. But other than that, if you have any questions, We would be happy to answer them; but we are ready to go Into public hearing if you are. Chairperson Schertz: Commissioner Engelbrecht? Mr. Engelbrecht: 1 have a question. Could you put the drawing back of the commercial site, please? Now, that's showing a street yard of some grass area. Mr. Hill: Yes, it is-right along this portion, Mr. Engelbrecht: Right. Mr. Hill: And then along this portion. Sir, Engelbrecht: Under this ordinance, under the proposed ordinance, is that required? Mr. Hill: The required yard? Mr. Engelbrecht: Yes, the street yard? Mr. Hill: it is not so much required in terms of being planted area. We are simply showing that the structure would have to be following the building line requirements in the ordinance. Mr. Engelbrechl: Right. In this case, you move the building line up so that they have more parking-so they were saving trees or what ever in the parking lot. Mr. Hill; One of the things that we at least wanted to demonstrate is to show you that there are ways if, and we did not put this in the ordinance. First of all to remind you, there was some • discussion about is it possible to reduce the set back? All right, and we simply wanted to show what that would be and also show, that there could be a reduction In credit for parking. There's still plenty-I think we could still rind space to put required parking-but the Idea was to simply give you an idea of the resulting vegetation on the site. Mr. Engelbrecht: Well, yes; but my question Is, would any of that vegetation, that street yard be • required, other than what is buffering the parking? • { Mr. Hill: No. But, see part of it is that we are trying to be flexible. The answer is yes and no. C We are requiring 20% of the site to be planting area; they've got to put it some where. - - - x la 32XIa 14 1 0 i • i { ' I i i i Planning and Zoning Minutes January28,1998 Page 6 t ~ I Mr. Engelbrecht: Right. Mr, Hill. That makes sense for them to put it there from a business standpoint, I think. Mr, Engelbrecht: I rail-d that question because 1 believe the whole issue, or one of the issues, that brought about concetrt for landscape was the concern that there be some vegetation in the street yard, and the last t,.,. had a 201Y& requirement for a street yard, which you can argue whether it be 20%, 10%, S% or whatever. But as I read this ordinance, there is, In essence, no absolute requirement for it. 1 mean you could put all of the planting, whatever, somewhere else, as long as you met the 2W@. Mr. [fill: That's right. And what we are basically proposing now-now, there are two parts to it. One of the things is, first of all, you are not going to have, you're not allowed to, even if there were some discussion-and right now we are not recommending allowing intrusions Into the required yards. A'e are not talking about altering the building lines at this point. And the reason that I think we are not recommending it Is because we like to see what happens when we start talking about how we use our street right-of-way and street tree policy; I'm afraid that we are going to get in the way of that. Mr. Engelbrecht; If we move building lines too much? Mr. [fill: If we start doing that now. We may want to do that later, but the other part of it is that if we are making an assumption that by requiring that 209/6 planting area, that they will put some, from a good business standpoint, In front of their building. But there Isn't-you're right-there is no guarantee, As long as they can meet the 20% requirement, I suppose, under our ordinance the way it's written, you could have pavement in front of this building-but they're going to have to make up for it some place else, Mr. Engelbrecht: Well, let me ask you this. Let's assume for a moment that 20416 of this lot was in the lloodplain, and they could, they had to leave it open and thrreby had met their 20"/. rule by having the floodplaln in the back some place in vegetation. Now they'd still have to buffer the parking lot, as I understand it. C' l Mr. lhli: That's correct. Mr. Engelbrecht: Okay. But they would not have to require street yard vegetation whatsoever if they did not want to. Mr. Hill: Well, the way I look at it is that they're going to make a business decision about how r closely they want to put their buildtrtg to the street. Either they're going to decide to put their y, parking in their required yard, and they're going to provide Interior landscaping, ptdmeter landscaping, and one tree within; or no parking space any further than 30 feet from the trunk of a tree. Okay. If they decide they don't want to put their parking lot near the front or near the r / frontage, then they're going to put their building up there, and they're going to be limited on how l - - 25 x ID 32XIO s ' 0 1 i Planning and Zoning Minutes January 28, 1998 f Page 7 1 ~ close they can get to the property line by the building line requirements, r Mr. Engelbrecht: Right. Right, Sir. Hill: Now, the point that I'm trying to get to is, does it make good business sense for that property owner to want to pave that instead of at least leaving some ground cover or some, you know, some vegetative cover. It's our experience that typically you will find some green space between a building and the lot line these days. That may not have been the case years back, but I think that things are changing a little bit. And we are making that leap of faith that in most cases between the building-or between the building line-and the street line or the public right-of- way line, there is going to be some vegetation, hopefully, but it's not a guarantee Mr. Engelbrecht: If the parking lot was up front, then there would have to be vegetation buffering the parking lot from the street. Mr. Hill: And shade cover for the parking lot. Mr. Engelbrecht: Right Mr. Hill: Yes. Mr. Engelbrecht: Okay. Thank you. Chairperson Schertz: Commissioner Oourdie: Ms. Oourdie: I'm just wondering. Wouldn't it have to go through the Development Review Committee-the approval of how the landscape's going to be laid out-so wouldn't that be one of the options available. So when it's being approved, it could be suggested that the reason why this Isn't working very well Is because the 201/9 Isn't distributed in a cohesive way, or something like that. I'm just wondering if that's an option to what Commissioner Engelbrecht is speaking of. Mr. Hill: I'm sure-DRC seems to be working quite well In terms of the relationship between the different departments during the plan review stage If we have the landscape plan, t think we would try to work with them and try to let them know what the City's objectives are. But we would be limited to what the language in the ordinance would contain. We're trying to make this as measurable and non-interpretative as we can. We want somebody to be able to walk in and say, "We satisfied your requirements, you know, we're ready to go to the next stage" Chairperson Schertt: Thank you. Commissioner Powell. Mr. Powell: Mr. Hill, when you were speaking to Mr. Engelbrecht. I thought I heard you shy-1 don't believe I heard you say, so I want to get it clarified--that there will be no parking piacts / within 50 feet of the trunk of the tree. That doesn't make sense. ~~in 32 0 0 Planning and Zoning Minutes January 28, 1998 Page 8 h Mr. Hill: I'm sorry. Did I say it incorrectly? Mr. Powell: Well, that's what 1 heard, I'm not saying that's what you said. Sir. Hill: I meant to say, if 1 did not say it correctly, that no parking space may be more than 50 feet from the trunk of the tree. Mr, Powell. Thank you. That helps out a lot. Chairperson Schertz: l have two questions regarding the plan that we see before us. If the proposed tree ordinance was not drawn on this plan, would In effect the same developer come through DRC-we would just simply leave the existing trees that are there trying to preserve It My point is what would look different about this plan? Mr. Hill: Well, again, we would have to go through and this has been a little bit frustrating to us recently, The current ordinance says that the developer must make a reasonable effort to preserve the trees. And here we get back into this, you know, you stick staff with trying to figure out what that word "reasonable' means, And they even said cost can be a consideration. If you look at this. Nancy has Indicated, that there are a couple of trees that would have to be removed. All right. We do not require tree removal permit any more In this particular procedure, Now, that may or may not, in most cities, require a tree removal permit. We're saying you make your decisions. If you take trees out, you're still going to have to make them up someplace else. And j if you take out large trees, the credit you might have been able to take may cost you more In terms of the trees. I mean, you could hase gotten a credit for 2V,•3 trees or something like that and, yet, you are going to have to plant more trees ;or the loss of one tree. So, It's a--you have, there the developer-you're going to have to make a choice, You know, does It make sense to try to work around the tree, or is it Just in the wrong place, and we're going to have to move it or get rid of it and plant new ones. Chairperson Schertz: So, your response was there's a lot of room for definition of what's reasonable, and it needs clarification. Mr, Hill: I think so, I don't like the way the language works... Chairperson Schertz: Okay, Mr. Hill; _simply because-and I think we need to talk about the limits of clearing and gra4ing that is In the ordinance---but right now, the presumption in our existing ordinance is the tree's there and it's supposed to stay there unless you can tell us why it has got to come out. And what %%e are doing Is we're flopping it around in the proposal in this by saying you show us where 4 your project is and why-where you need to disturb land--and then prove to us why you have to go outside that and disturb the whole--I mean tae are trying to avold clear cutting. So, we are saying show us, at minimum, what you need to do for your project and then leave the rest of your land alone if It's not necessary to remove the trees. So, It's it little bit different. in 32 X I 0 I Planning and Zoning Minutes January 28, 1998 Page 9 Chairperson Schertz: No. That makes sense. I appreciate that, and I had one other question, I know it was put up on the screen, but it was put up and I didn't catch it. Talk to me about how the tree ordinance effects apartment projects. Mr. Hill: Okay. The same, Chairperson Schertz It's the same. It's the 20 trees per acre rule. Mr. Hill: We're all partneri. Chairperson Schertz: Okay. Okay. I saw it, but I didn't catch it fast enough. Sir. }fill: The only other thing I was going to mention to you is that-or it's, I'm sorry-it's proportionally the same in ratio to the land that you're developing. The one thing I did want to mention to you though is that the current landscape requirements would not require this many trees. We're req Aring more trees In this. Okay? Chairperson Schertz: Thank you. Commissioner Powell, Mr. Powell: this particular ordinance does not require a tree removal permit. Then you said if they rer.iovLd a large tree It would have a different effect than a small tree. My question is how would you know' If there's no removal permit, and they give you a plan for what It's going to be when they're finished, how do you know what's out there now if you don't go out there for a removal permit? Mr. Hill: Well, what we do require Is a tree inventory at the time that the preliminary plat Is submitted. So. before they begin any construction, we know what's out there. Chairperson Schertz, Because we check it or because we take their word at it Mr. Hill: Well, no. It's got to be, it's not so much approved, but it's an acceptable, we have to accept that product and if we need to send Inspectors out to check their Inventory we will do so. • But that will become a file document. It requires no action other than to properly Identified the location, species and health or the trees. Then the nnal, what you want to do with the site is not required at the time of the preliminary plat, but at the time that they're preparing their construction plans that they have to do anyhow, that's when we would ask them to designate their limits of clearing and grading and show how they plan to comply with the ordinance at that time. And again, It's before they're allowed to begin their construction. • Chairperson Schertz: All right. Commissioner Engiebrecht • C Mr. Engelbrecht: I want to go back for a moment. In some vjays I'm asking this for those folks who may be listening In as well as those In the audience, We have been driven In the past by a , 32XIO ,rte a I I i Planning and Zoning Minutes January 28,1498 Page 10 desire, I believe, to mitigate strip commercial as we've seen it historically In Denton, and, two, to enhance our entry ways. I'd like to start with the first one and suggest, and ask, with this ordinance, and I know this kind of puts you on the spot in a way, pick a spot, a place on University Drive, are you familiar with Albertson's and their parking lot and that little strip commercial center there which virtually has nothing as it sits now. Assuming they were putting that In today, what would they be required to do in terms of vegetation In the front of their facility and through the parking lot, I Mr. iliii: Well, rirst of all, for that platted lot they'd have to have 20°14 planting area, They'd also have to, what would a reasonable estimate of the size of that be, about 10.15 acres maybe. It's probably even bigger than that. Do you think so? Let's assume it's, let's say it's 10 acres. Okay, so you'd have 200 trees on that property. All right. You'd also, in terms of distribution, they would have to be putting planting area in interior to that and have perimeter screening of that parking lot because it's out in front and visible from the right-of-way, And so you're going to have planted medians or tree Islands or something interior to that because there is no way they could go around the perimeter of that parking lot and still be able to have no parking space any more than SO feet from the trunk of a tree, So, they would have to go Interior. The other thing that could happen, and I don't see it happening, l was trying to work this out and I find It hard to believe that anybody could get Into this situation, but if you can't meet the no parking space being more than 50 feet from the trunk of a tree, you could, would have to fulfill that even If it meant going over 20 tree per acre. 1 jus! don't see that happening. Sir, Engelbrecht; Yes. Mr. llill; But I haven't done, actually looked at a big parking lot. And 1 think maybe we need to do that. That's a good point, Air, Engelbrecht; Well the reason 1 say that is that I think it's important since there has historically been a great deal of public interest In mitigating strip commerclal, and of sort of, and I'm sorry I didn't ask this at the last meeting, ask you to prepare something like that, to sort of project what that would look like. This is a great example except that the parking's In the rear M and we have so many where the parking h the other way around that 1 think it would be bencricial to show folks, you know , what we would have, what would be required, Mr. Hilt: 'that's fairly easy to do, and really what you're tasking about Is an exercise In parking lot landscaping, Because that's what's going to happen. Air. Engelbrecht: Yes. Yes, and l just want to point out, the other thing that 1, aspect of, of landscaping ordinances in the past, I think In this town, have been driven by, in more recent times, entranceways, concerns for enhancement of our entranceways, and so long as It parking lot r r Is In the front of the building, we're gohtg to have a certain amount of screening and tree requirements there. It they chose to put the parking lots in the rear of the buildings, then, however, we have no assurance that there will be any trees, any form of vegetation other than / what they want to put In voluntarily, i ~t~ 10 32X10 0 Planning and Zoning Minutes January 28,1998 / Page 11 Mr. Hill: With the exception, that hopefully... Mr. Engelbrecht: They have to meet 20%. Mr. Hill: The thing that we've put In here though, at the reserve section, that we will be moving on fairly quickly though Is the street tree component. Mr. Engelbrecht, Okay. Mr, Hill: And hopefully, that will fill that vuid. Again, I hesitate to force that at this point in time. I suppose we could put something in about street trees with the provision that they go In only, if they're not going to interfere with underground utilities but I'd rather wait and do it the tight way. Mr, EngelbrechC 1 understand, Thank you. Chairperson Schertz: At this time, l believe we've asked all out questions. Thank you, At this time, I would like to listen to all the people in favor of the proposed tree ordinance, and 1'd like to start this evening with Sir, Cooper, t ( Sir, John Cooper: Madam Chairman, Commissioners. Chairperson Schertz, Could you give us your name and address, please? Mr. Cooper: I'm John Cooper and 1'm...1 live at 2120 Olengarden in Denton, and I'm also the Chairman of the Tree Board here In Denton, So, I have an interest In this ordinance, too. Also, I'm Extension Horticulturist for the County, and 1 was a patty to of a member of the Committee that "tote It--the original document that you are considering a revislon on. 1 had been requested to cone to speak on behalf of the soils aspect-maybe answer any questions. I think those have generally been addressed. I'll be glad to answer any questions on that that you would like, But, I would like to say that David Hill and Nancy McBeth, and I believe there's a Mark here somewhere--because I ran across him somewhere-that had done some research at the Natural Resources Conservation Service. I was over there yesterday talking with their conservationist. I think we need to address the soil concerns because we do have changes In that root environment, R'hcn we create these landform changes for drainage and other aspects, we drastically change the soil texture and condition, structure, and tootability. So, I would propose and I did say that this, all this document is vastly Improved. It's a vast Improvement over what wt have currently-in all respects. It's better to have ten years to review and look and see how the changes can be made. I'm glad this Is being revisited because It was time. Everything I've seen Is very good. I would like to see you look at those species lists that I've recommended, and 1 jV1 might mention that the list that you received that is for wltdscoping or wildlife habitat-was a list that was given directly to the people, the Friends of the Denton South Lakes Park Nature Center, Benny Simpson was our Research Horticulturist, the Texas A & M Research and Extension 1{! Y 32X e , 0 Planning and Zoning Minutes January 28, 1998 Page 12 Center in north Dallas. Some of y'all might remember as RENER, and he-3 years ago before he passed away, gave us this list that you have in your hand that represents the trees and shrubs ' that he recommends. He also gave us some vines and flowers, wildflowers and grasses, But, the trees there represent, for your concerns, the trees that he considered of ornamental value that grow naturally within a 50-mile radius of Denton, encompassing 9 counties. And, 1 think that makes an excellent list to protect the trees that are growing naturally. Those would also serve, as they become available through the nurseries for planting. Some of them already are. In fact, on the ornamental plant list, the one that introduced species as well as the native species that I recommend, those are commercially available. Many of those are; in fact I would say more than half of those are, native trees, So, when we get the trees, we are talking considerably on the native side, And that--those two lists will give you a conservation list--that is, those that grow naturally within a 50-mile radius of Denton from Benny Simpson. And then, the developed, introduced or commercially available species that you can plant and buy from your nursery. But, back to the soil. I think we need to consider that when we develop land-and it is a national issue-urbanization and depletion, Is that one minute? Chairperson Schertz: Just a reminder. Mr. Cooper. Okay. The depletion of soils is a concern nationally, and, of course, our populations developed around agricultural centers. And many of our soils are good. What I would like to see rather than bury the soils, I would like to sec them conserved. I would like to l see them-a site inventory made and collect that soil, stockpile it. The better developers do this already. And then put that soil In stockpiles that they can put back Into the planting sites, That is that 204a required. And say, even if you have a shallow soil, say a 6-Inch soil, you could still, utilizing that, develop a pretty good, deep planting soil, deeper than it was originally there. And so I think that some consideration should be made to soil conservation, stockpiling that soil. conserving that soil, either for sale or for use on the property as It's necessary. If there's a surplus, which I suspect there will be, then that should be, you know, that could be sold as a resource, But, my urging would be not to bury It. It's a valuable resource. If you want fill soil, buy some soil that Is not topsoil. But, let's stockpile our topsoil. What we can do-and there are tests that can be run; Texas A k M1f has a Soils laboratory, and we can run for $20 and a two, r week turnaround, they can take this soil, they can send it off and have it analyzed for minerals, pl i, salinity, and texture, And that is just a matter of measuring the depth that you want, Talking with Todd NImick, the Conservationist over there, the Ergincer at the Conservationist's Office Week, we talked long and hard about It, We talked about using Cut Munsell color charts and our chemist at A X NI likes the Cut Munselt color charts. We could Install drainage lines, We could actually take a "perc" test-do an on-site percolation test. There are many different ways tp do it, but 1 think on the whole the simplicity of this ordinance and the application of it should be preserved and 1 would vote In favor of an I8•Inch topsoil base and forget what's underneath it. And let the chips fall where they may. I think you will find an Improvement, Because what I'm hoping Is that this 20% that goes in will last and will be there. And with the right species and with the right soil-and, again, you have soil descriptions here, and we have a few soil survey books left, they are rapidly going out of print, but the soils that are there are still In the book-- you can get that, you can run the test, you can measure the depth. Then you have something 32 X I O e 0 .ate Planning and Zoning Minutes January 28, 1998 Page 13 C. that's going to be there for a long, long time. Now, the other consideration was the water. And if you have drainage runoff into the planting area and you have good soil texture and it's been analyzed-pH, salinity, ctc. if you have good topsoil, that top A horizon I'm talking about. You might read through that material. It's very Interesting. It gives you A, B, C, 131, 82, parent, down below, gives you a soil profile. The top A horizon Is what we're talking about conserving. That's where the roots go. That's the definition of it. That's where the plants root in. Below that, that's where the plants stop-plant roots stop. And so, we want to conserve that. If wti do that now, If we have some infiltration into that area, that's good. If it has rainfall only over that soil column, then that's all we're going to get. The first 3 years of establishment are critical in terms of moisture, rooting those new plants. And until they're rooted in, I'm afraid that we need to be concemed that there is access to water and some provision for water made. It's only in the best Interest of the developer that they be forewarned. And currently, the ordinance says a hose be within a 100 feet of the planting area. And I would say that's plenty good if it's worked until now, But, I would hesitate to think that everyone will have a tank truck. Most people like plumbing to get access. You can haul water anywhere you want to and people can do that, but you might not have that water truck when you want it. R's good to have a hose be within a 100 feet of your planting bed, Okay, That's all 1 needed to say, Thank you very much. Chairperson Schertz: I'm sorry. Thank you. I think we have a few questions. Commissioner Engelbrecht. Sir. Engelbrecht: Yes, first off. 1 just want to ask you. 1 don't see the Bradford pear on this list of trees. 1 was Just sort of curious about that. Air, Cooper: On the proposed planting list? hit. Engelbrecht, Right. I asked that because we have so many in town, Mr. Cooper: I actually didn't develop that one. The two that 1 developed had my name on them. And those were handed out just before this meeting. bit. E;ngclbrecht: Right. Mr. Cooper: Now, with Bradford pear, we do have considerable problems with that one, as far as limb breakage, And I would urge you to consider the Aristocrat. It's a much, a stronger tree. Air, Engelbrecht: Whatever kind. I was just curious to know why it was absent and that's fine, I just didn't know why It wasn't on there. Mr. Cooper: I didn't make that list so 1 don't know why It didn't make that list. But, I wouldn't recommend it. Mr. Engelbrechl: One other question, John. As 1 see this ordinance, It's being driven by this / C Idea or a forest concept, which would suggest to me a mix of trees. 25 1.0 32XIO s 0 Planning and Zoning Minutes January 28,1998 Page 14 Mr. Cooper: Correct. Sir, Engelbrecht: And, now there's a great variety of potential trees to be used among all these lists. Mr. Cooper: True, Mr. Engelbrecht: Tlowever, I don't know how many of those are commercially available to be purchased in large quantities. Mr. Cooper: All on the ornamental plant list that I gave to you-Nancy gave It to you for me- are available commercially. Not very many of the others on the native plant. That's more of a conversation list. So, unless they're available In the nursery, they didn't go on that ornamental planting recommendation-the recommend-planting list, Mr. Engelbrecht: Okay. To carry on with that. Thank you. 'T'hen, If we desire to have a mix of trees, is it, do you, as a professional In this area, see any necessity to require that there be some mix per site? Mr. Cooper: Well, I think probably the evidence that we do have so many of a single type going. Seems like trees go In fads and people --like so many things they &-go, In fads. And those tend to go In waves that persist for so long. So wt do have a predominance of one over a certain age range. But, I think over time, if we'll keep a watch on that, I think I'm urging people to plant the Aristocrat versus the Bradford, But, one thing we do in the Tree Program, the urban and Demon Is a Tree City USA city, it's due to all the things the City does to promote urban forest, One of the things the Tree Board does to support that Is we have a ReLeaf Program. In fact, the Parks and Recreation has had that for years. And the Tree Board has assisted the Parks Board over the past several years to find trees that need promoting or are not planted enough. And end up, you know, you see that people recognize the benefits and plant those and help make them more available through the nurseries and through the City Parks programs. There Is an effort constantly to see that we have a good mix. And the Forest Service and the Texas Forest Service is a sister agency of the Agriculture Extension Service and A k M System. And we work closely • with them; and our urban forester, Larry Shopwell out of the Oateway Division In Fort Worth, recommends 10 genus Is a good mix. If you have no more than 10% of your forest in any one genus, you're doing fine, And I think the evidence of having predominately one species where we have Oak wilt in San Antonio, Austin areas, you see when one disease takes over; the IDA wilt goes through Live Oaks like firer And that's what-and the some thing with a plant like the American Elm, the Dutch elm disease, It can happen, We can't be sure when it won't happen. r So, we hope it doesn't happen-nothing has happened so far to the Post Oak, But that's our • f predominant climax tree mix species here. So far, nothing has hit It except, you know, people, We're working on that with this ordinance here. So, at least there Is some mind to this madness. u But, I think this ordinance does very well to address some of the comp!icatlons with the previous one. It strengthens actually the conversation of Post Oaks. I'm very hopeful. I see In 32x10 o , 0 Planning and Zoning Minutes January 28, 1998 Page 15 C very positive results occurring from this ordinance change, Mr. Engelbrecht; Thank you, Chairperson Schenz: Thank you, I think that's all the questions we have right now. Is there anyone else in the audience to speak in favor? Would you please address the podium and give us your name and address. Ms. Nancy Upstlck; My name is Nancy Upstick, My address is 104 East Brown Terrance, Shady Shores, Texas. Thank you again for allowing us to speak here, 1 just picked up a copy of the revised Tree Ordinance tonight, so,1 haven't had a chance to look through It thoroughly. But, I was very excited to see the specifie things it takes to protect the trees as far as changing the grades on the hills, vehicles being parked underneath the trees and things like that. I think that's a great strength in this. And I'm speaking for because it's being strengthened a lot, And the other thing I wanted to share with you-I had a chance to go to a tree seminar several weeks ago In Grapevine, They had the U.S. Forestry Service and Harold Courtney, who is the Fort Worth Forester, I'm not sure if you have this information, but I thought I would share just a little bit with you. As I say, I'm not an expert In this, but, you can ask any questions of Harold Courtney. What he did was, Fort Worth was chosen to do a program using the benefit costs analysis to I manage an urban forest. So, they went through this whole, entire procesi, and 1 guess it's a computer program. 1 think Cecile Carson knows more about that, and I'm sure Dave Hill does also. I'll show you what 1 found was very exciting. The inventory results, that was exciting too, but that's not what 1 want to show. Okay. Benefits Cost Analysis, What that did, they've broken it down into street trees parks, yards, vacant, commercial, Institutional type trees. And what these ratios mean are for every dollar spent on a street tree, the benefit would be $1.32, For Parks, for every dollar spent on the benefits, there would be $28.29, and so on and so forth. As I say, I'm not on expert In this, but l larold Courtney could explain It further, i think, you know, a lot of people are concerned about the dollar basis of conserving trees. They know what this means as far as economically. And so, I'll leave this with you and, again, I'm speaking for this ordinance 1 think it's going to be a great thing. Thank you, ,k Chairperson Schcrtz: Thank you. Are there any questions? Anyone else to speak in favor. Anyone to speak In favor. Is there anyone who would like to speak In opposition? Anyone to 0 speak In opposition. Seeing no opposition, 1 would ask Mr, Hill if he would have any final remarks, Mr, Ifill: I would, l guess, conclude by letting you know that, again, first of all, the structure of this ordinance, i think, is going to have to be cleaned up. I've talked with Mr. Martin, and I think he knows and we've discussed the fact that this really does not match the way our zoning code Is • aligned, So, he's going to have to rework this a tittle bit. One thing I've found which made me, you know, screech a little bit, when I looked at it Is. If you look on page 6, it goes from Section 6 to 8. There Is no hidden Section 7, So, we will fix those kinds of blurbs. The thing I did tell C you and I didn't prepare an actual graphic for you or anything. I did tell you I would try to give you a list or issues that may not come out fully In the ordinance but items that we know were _ , x10 32x10 ~ e n Planning and Zoning Minutes January 28, 1999 Page 16 1 I requested that, at this time, are not In the ordinance. I want to make it really clear. There are some things in here that maybe people might not like or might like. There are some items that are not in there that have people interested in them as well. I'd like to go through them very quickly. Things that are not in the ordinance; there Is no reference to a water source. And I'm still not certain if we want to go back into having some kind of water bib requirement within some distance of landscaping. The thing that I think that does is it promotes sprinklering. I don't think-I think we're finding more and more-that really Is not the best way to provide water to plants. So, If we want to be water conservation-oriented, do we really want to have some kind of plumbing connection that Is going to spray water into the air? There is nothing to talk about underground Irrigation. But there are some wonderful systems that are Inexpensive that can allow the kind of bleeder hoses that feed the root system without exposing the water to tasporation We did not put that in because it's an expense. But, we want to say, at least, mention it, and see If you have comments that you wanted to give to us as we go to City Council, Street trees are a reserved section and would not be Implemented at this point in time. We are not requiring a registered landscape architect That was a comment that was asktd for by some folks that had trade some comments. We do not require a licensed irrigation expert to provide a plan for Irrigation. We do not have a landscape administrator on staff. By contrast, we actually said keep it simple and allow existing staff to work with a fairly reasonable set of both administrative and enforcement type of duties. And I have checked with our Inspections and Code Enforcement people, and they feel that this is an Improvement over some of the confusion of the existing ordinance. We do not have anything that starts to talk about stewardshlp types of 1 concepts. We are not asking that wetlands or environmentally sensitive areas be described or Identified in a landscape plan. So, this Is a landscape ordinance, It is not an ecologically complete or exhaustive type of ordinance. We do not have any kind of a tree replacement requirement, if you'll look at your matrix, many cities have a replacement in ileu Of. What we're saying is, we're requiring 20 trees per acre. You figure out how to do it and everybody does it. So-it's a little-it's going t"uite honestly, I think this Is a much different orientation than you'll find In terms of comparable ordinances that we provided in your packets, t think you'll find that the City of Dallas is probably 50 pages. You know so there's a big dinerence. They each have some very, very excruciatingly fine details about how you preserve o. ;d replace trees if you remove them, There is no mandatory tree preservation. We have tree credits. It's an incentive system, The only time we have mandatory tree preservation is for the public sector. The reason we have that is we give them an out so they do not have to put trees • where they're going to be In harm's way, I'll say, for example, in the Instance of a drainage channel, so, tht they are not replanting where they need to keep it clear of vegetation, 'T'here is no alternative compliance, but t think we could put that in there. Really, what that is allowing is some degree of administrative flexibility, So, I don't really have a, It's not in there but, I think we've given the property owner or the developer quite a bit of flexibility simply by the way the performance guidelines are stated, We don't give credits rot innovative dtsign. Sometimes, that is a type of item you see In an ordinance. And then we do not absolutely require installation prior to building occupancy, We are cutting them a little bit of slack so that If It's not the proper season or whatever, they can provide bond In Ileu of Installation so that they can procted with their project. But, wt have some way of, the one thing that we're trying to steer clear of Is this ( } thing called, which I think is a bit ors ghosts called a temporary certificate of occupancy, I don't 4 15 • 32X • Planning and Zoning Minutes January 28, 1998 Page 17 think they really exist. But, so, that's really, I wanted to give you an idea of what we're getting into and what we're not getting intl. Okay, The last hem I wanted to bring to your attention was that we did add half of a tree credit under Section SC. I told you I would; l thought that we needed to beef them up a little bit at least. So, we added that the 6- to 12-Inch tree would be given a credit of I or 0.3 or half a credit in the outline that I gave you at the work session. We're giving one now, So, everybody, every one of him or her went up by half of a credit. So, If you have any other questions, I'd be happy to answer them. Chairperson Schertz: We do. Commissioner Powell, would you please start? Mr. Powell: Yes, the last time we talked about this, I took from what you said that this would affect new subdivisions only. When I read it, I don't see that, because it says on Page 3 down at the bottom--it says, all property located within the city limits of Denton. Then when you go to the next page, it shows that if you remodel beyond a certain percentage or if you make a larger parking lot or whatever, that you're looking at the ordinance, So, it's no longer new subdivisions. And maybe it wasn't last time, but I gathered that. Mr. Hill: Okay, One thing I did say was that we haven't worked out the details. But, we did : know that there had to be-we were going to recommend-some threshold where redevelopment of a slit or a major alteration would kick in or trigger these requirements. The one thing, the ordinances that I've worked on before, I've had one where there is actually an administrative relief clause that Indicated that if compliance meant having to tear up existing pavement or concrete that they did not have to comply. There are some alternatives to that. But, to simply say that once that site has been, has gone through Its construction process and has been issued a certificate of occupancy, that we will never revisit that slit ever again, i think over the longer term most sites are redeveloped over their life, And there needs to be some trigger, This may not be exactly the right way. But the Intent wer when major alterations or Investments are made, that they become partners too, .y Sir. Powell; It's quite possible that I misunderstood what you said, I gathered, I don't know where I got if from, but it was strictly new development. Mr, Hill: Well, Mr, Powell: At any rate, you coveted that fine. Mr,Hill:Okay. Yes sir, • 0 • Sir, Powell: Have you given any consideration to the additional costs for staff for review, for approval, for tree Inventory and enforcement, It appears to me like this is going to cost us a tot of staff. You'rt not going to be able to handle it rfx1❑ 32X o • 0 i i I Planning and Zoning Minutes January 28, 1998 Page 18 Mr. lfiil: My feeling Is that right now, me are ready to administer the existing ordinance through our Inspections and Code Enforctment staff. So, what happened is, quite honestly, they do not always get all the Information they need in order to conduct a proper review of plans, and they have to play games with determining what the street yard is. They have to see if the calculations have been done properly. They feel that it's confusing for them, and they spend a lot of time trying to figure out whether compliance has been met or not, The major part of this when it comes to large site development Is going to shift to DRC. And DRC can handle it, Okay? No question about it, 1 mean they handle whatever comes their way. And we can go from an agenda from 8:00 in the morning until 5:00 at night. And then other times we only have 9,00 in the morning until 1030, So, we just flex with the workload on that one, Air. Powell; Have any studies been made or is there any indication at all of what the additional cost will be for the developer for these additional plans that he has to provide. Mr. Hill: My estimate is that you take the requirement of the street yards and what you typically sec with street yard trees being required. I am only looking at the tree cost right at this point in time. There Is no question that there will. be an additional cost in terms of the land that has to be reserved for planting area. No question at all about that. Sir. Powell; No, I wasn't getting Into that. Mr. I fill: Okuy. But the trees... Mr. Powell ,.,f was talking about the cost of plans... Sir, Hill; Okay. Sir. Powell: and things that he has to hire people to do. Sir. I fill; Well, in terms of the professional services, they may need a landscape architect. They may be able to find a landscape contractor that can help them out, And there will be an additional consulting cost if they decide to go that mutt, Many of the developers we see coming in are contracting those services anyway. In terms of the trees, I think that what we're using, as a rough ballpark figure, is $100 per diameter Inch of tree. And £f you estimate that, we're probably • requiring about twice as many trees es would normally be required, and that would be, say you got 10 trees per acre more than would normally have been required, at 3 Inches per tree, If you had to install all brand new trees, that would be $300 a tree. So, it would be $3,000 for an acre of development, T hat's a real rough estimate, and If you did, you know, the math, we could cgme up with a little bit better Idea of the cost if we needed to. The other thing that I would like to offer to you is, because we got you the ordinance so late, the work session for City Council ;s r going to be on February 10. 1 think you have a meeting on the I i th, If you'd like to discuss this • • again on the 111 before they have their final public hearing, and you would like to offer more Input, we'd be happy to put this on the agenda if you'd like us to give you some more Information. But, I think we're talking In the thousands of dollars on a typical acre and a magnitude of some"here around 50% more for trees. ~'tfr r r ill Ire 32x o . 0 M c+zz?a Planning and ?oning Minutes January28, 1999 Page 19 C Mr. Powell: Thank you. " Chairperson Scw!rtz: Commissioner Gourdie, please. Nis. Oourdie: Mr. Hill, I had a few questions as I went through this. Being that there is no tree preservation requirement in this [just had some questions as to how we're going to, such as page 4, number 1 under S.C,I • cleaning equipment and liquid disposal. If the trees that these people are not being monitored they would go ahead and do it and the tree dies, how do we handle a situation In that case? This whole section, in reality, there is no tree preservation and no reason why they wouldn't park their cars under the trees. So, I'm not feeling comfortable with that. Now did, in your mind do you balance that? Mr. Hill: The way that we have worded this right now Is that there has to be some kind of a barricade, a temporary snow fence, orange mesh fence, or something like that that protects the I critical root zone. So it's going to be fairly easy for an Inspector to see if a preserved tree has no protection around It, That's really your primary point of protection. In terms of whether or not the dumped chemicals, it's going to be a tough call, but there are several different kinds of Inspectors from the City that visit these sites. The other point I think that 1 need to bring up is , more and more we are finding developers, and Mark and 1, and this is with a developer that is attempting to come to Denton and Invest, lie actually selects his contractors based upon his working relationship with them and he doesn't even have to put mesh around it. Ile basically knows they're going to try their best to save every tree they can and they have that understanding you don't hire them to build more houses if they start knocking down trees that you want to save. h's not a fail safe system but the other thing, too, Is that same of the more obnoslous types of damage such as, some kind of mechanical piece of equipment actually scraping a tree those things can be reconciled very quickly at the time that the final inspections are conducted, Some of the other things that could be a little bit more slow In checking is if the tree Is poisoned and we don't know that something has been dumped into the ground those we are going to lose and may not even know that for two or three years afterwards. Ms. Gourdie, And the other thing was Mr, Cooper spoke of the need to water and maintain It for at least three years, again, if we do not have that happen we'll lose those trees. 1 guess that I'm f very uncomfortable with the fact that there Is no repercussion for these people if they decide not to water, if they decide that what's a tree here, what's a tree there and I'm just going to dump It. 1 think that we need to have something that says you're not going to do this or this is the consequence, I don't see any consequences to anyone's actions. 1 believe In trusting people,,but I also have seen too many things that I took for granted and I realize that I'm pretty naive in a lot of situations. I'm learning not to be trustful anymore. So this is my questlon-maybe 1 am off balance asking this, but I think there should be some kind of consequence and that would be replacement of the trees. Mr, Bill: Well, I guess that the way that It Is set up is pretty standard for a City of Denton C ordinance, Our City Attorney can answer questions that I can't If you have the dttail, On page 8 '32 X s 0 Planning and Zoning Minutes January 28, 1998 Page 20 i there is a section that says "Penalties' and it basically that there will be up to a 5500 fine for What is defined as incident of violation. There are some fines for that, but in terms of making them go in and replace a tree, there is also, if it's not here it's intended to be in here, that if you have a approved landscape plan for a commercial property in particular that would have to be replaced. If we inspect it and find that trees have been removed. The assumption that we are making is that if you can get the tree in preserved state or it's planted, newly planted safe and secure after the fact of the subdivisi,i. Improvements and home construction that the residential property owner is going to hopefully take care of those trees, and that's an assumption we are making. We also know that there are going to be some residential property owners that are going to cut them down and put a swimming pool in. At that point that is where we release our effort on the residential side. Ms. Gourdie: Where does that 5500 go? Mr. Hill: I assume that it would simply go into the general fund. Nis, Gourdie: Should that be questioned or marked or? Mr. Hill: If you would like to make a recommendation on that we'll carry that to Council, Ms. Gourdie: Ijust wondered Mr. dill: You mean like a tree fund? Ms. Gourdie: I'm not sure. I'm just saying that so many things come before us and that money involved in a situation that it be dedicated to certain funds and not just put in a general fund or something spent for something that really didn't deal with trees or landscaping, or, I don't know. Mr, Hill: I don't know of any instance where violation money is earmarked for specific uses, but we carry that comment forward to Council. 1 Nis. Gourdie: My other question was on page 5. again were in section 5, area D, 42, talking about II the residential subdivision and you gave the, the last time you gave the example of the Johnson i stanch that's going. in how if we had, if this had been available we could had, 1 guess Commissioner Fnglebrecht said about five acres of open land if we would had the 1(% rule. My question was though, when this piece came originally before the Planning and Zoning and the Council it was for an SF6 not an SF7 and it was negotiated up to SF7. My question is this based on their initial request tor is this based on the final approval? Mr. Hill: It would be based upon the approved zoning for that property, not 0 a prc posed. For 0 example, if somebody comes in with an SF6 where they have shown clusters am they have reduced those 6,000 square foot lots by 600 square feet each and Council says "No, we want ) mi to go SF7, it's back to the drawing boards, 1 in 32JO O Planning and Zoning Minutes January28,1998 r Page 21 Ms. Gourdie: Okay, I wasn't sure how that was taken care of. And lastly, Nancy, I think you did ` a great job on all the visuals and it really helped me to understand versus seeing a chart. 1 can really visually see what y'all are talking about so 1 really appreciate your time and everything. Chairperson Schertz: Commissioner Ganzer did you release your button, or did you have something to say? Ms. Gamer: I released my button. The longer 1 sat here the Chairperson Schertz: more got answered. Ms. Gamer: People were asking the same thing 1 was going to ask. Chairperson Schertz: Thank you. I just didn't want to leave you out. Commissioner Moreno. Mr. Moreno: Yes, Madam Chair, I'm sorry that I was late, Have you already had an opportunity to review the exhibits that were in our backup. Mr. Hill, We did briefly. Yes. Mr. Moreno: Briefly? Under Exhibit F, your Actual Project Comparisons. You compared what might have happened as 1 understand it the Denton Linco"ercury project. Mr. Hill: Yes. Mr. Moreno: I guess my basic question is would that project have been allowed to have been built under your proposed ordinance? Mr. Hill; No it would not have. And for the reason if you go down to pervious surface provided you will see that the project, and pervious surface is defined pretty much as planting area. It's the area t'.t is not covered by building footprint or pavement so the project provided 12% pervious ~ ,rface and we're requiring 200/6. That's where the hitch would have been. I think they had an opportunity In other places on that site plan to plant other trees without creating new planting area whether or not that could have gone 110 I don't know. I would suspect they would've had to provide more planting areajust for the trees even if the 201/6 requirement wasn't there. Mr. Moreno: Okay. i guess my concern is arc we "shooing" car dealers away from Denton by this type of an ordinance or any business that requires a large parking lot or large parking area? r Mr. Hill: Well, what we are doing.,. Mr. Moreno: A hospital- Mr. Hill: Absolutely, MEW" 25 10 32x101 1. O i Planning and Zoning Minutes January 28, 1998 Page 22 Mr. Moreno: or another WalMart... Mr. Hill: I understand. Mr. Moreno: or home Depot or something of that nature. Mr. Hill: What we are telling them is that if you arc going to develop here you have to have a site large enough to provide the 201/6, that's what we are doing and other cities do t:tat. What I think, the way that I would characterize Denton Lincoln/Mercury it is not the same comparison, because they had an approved concept plan that had a building envelope on it. So it carried with it, for the sake of argument, the assumption that they could build within certain confines. So, and if, because of the fact that we had to deal with an older or previously approved concept plan, that set the tone for the type of develop proposal that you saw. If this ordinance were adopted it would simply tell potential investors this is what you need to do in order to look for a marketable site for the size of development that you want. It will require them to look for a larger site. Mr. Moreno: I had one other question and I think 1 know the answer, but under your graph of the interim landscape page 4, section 4, under Exclusions, it says "property being actively used for production of food products" My employer is a manufacturer of food products, you're not going to exclude him, are you? I'm being a little facetious. Mr. Hill: No, well, that's a good point. If we need to say something that's using the land for food, l think that is something we need to check and we appreciate the comment. Mr, Moreno: That's it. S Chairperson Schertz: Thank you. Mr, Hill: Even though your employer may be mad at you now, ChairpersonSchertz: Commissioner Ganzer. • Ms. Ganzcr: I did think of something. I started writing notes and remembered what I was going to say. I want to go back and clarify something on existing lots and existing homes now.. You said if someone adds on to their home they have to get a building permit. Did you say they might have to go Into and plant a couple of more trees if i add onto my home and 1 only have two trees in my yard and I want an SFIO, am 1 going to have to plant three more trees on my own 1 land that I already own? Is that what it's saying? • Mr. Hill: No it's not. The, let's see. I need to direct you to the proper,.,, and 1 think maybe we • • can clarify this because it Is a little bit confusing. i Ile Mr, EngelbrechL Section 3, the second paragraph. r ?5 32 x ❑ o *ARAN • o 4wrw Planningand Zoning Minutes January 28, 1998 / Page 23 l Mr. Hill: Let's see, in the,.. Ms. Ganzer: Okay, because I did here you say something earlier about if somebody adds on.,. Mr. Hill: In the applicability we talk about what happens for residential. I'm sorry. We did say it twice. It says, at the bottom of page 3 it says, "The requirements of this chapter will cease to be in effect upon the satisfactory completion of the final inspection for single family and duplex residential dwellings." if you go back to page 7 under maintenance requirements, I'm sorry. I had it. Ms. Ganzer. No, the 7's not there - page 7. Mr. Hill: Or page, it is right. Down on page 7 under 8.1 the final sentence in that paragraph says that, "Once the final inspection has been completed for single-family or duplex residential dwelling the requirements in this article no longer apply," So both in the enforcement part... Ms. Ganzer: But didn't you say something earlier about if somebody adds on to their home and having to get building permits..... { Mr. Hill: That would be for non-residential and multifamily. Ms. Ganzer. All right. That's how I misunderstood then, because 1 did hear you say something about that. Sir. Hill: Right. No, no. We did talk about that. Nis. Ganzer: All right. Thank you. Chairperson Schertz: Commissioner Apple. Ms. Apple: Dave,just my two cents. I'm a little concerned about the removal of anything to do with protected trees and the tree preservation section of the previous ordinance. I'm a little 0 uncomfortable not having the permits to remove the tree. I realize the credits in place to enccurage the developers to do the right thing but I guess my concern would be someone who would have the money and not care and wipe out an entire section of an old stand of trees and put the required number of new trees in it's place. Just a comment that that's just my biggest concern and I appreciate all the work that you all have done. Certainly the size of this one is ' boner and is much easier to comprehend, but I am concerned that the tree preservation seems to be thrown out the window. 0 Ma Hill: Okay, the only, and I think you are right and there are some choices to be made. We C may end up on the perspective that we will have more questions about do we need to actually go back to some kind of tree removal permitting system or do we need to actually require 32X10 • Planning and Zoning Minutes January 28, 1998 Page 24 replacement in lieu of removal. Okay, now to me that, 1 guess that's not the way we are going because that, we are getting back into en individual tree-by-tree mentality and I am more interested in the overall urban forest by the way this has worked out. But, if 1 can have you look at page 2-and it's in the definitions right now and I think we are going to have to move that, but if you look at under the definition of "limits of clearing and grading;' I spoke about this just a little bit before the public hearing was opened, and it's kind of an inverse way of looking at it. What it is saying is instead of you coming in and inventorying all your trees and telling us which ones you want to remove and getting a permit for it, we're saying you go out and Inventory your trees, declare your limits of clearing and grading based upon certain aspects, and we're saying street construction, necessarily slope construction, public service and utility easements, right"f- way, building coverage, driveways, so we are saying identify where your structural elements need to be, draw a limit of grading and clearing and grading line around that for these specific purposes, and then show us why.,. so that, if you want to clear and grade you have to stay within the lines basically. If you want to do the whole site you better show us that there is good reason to have to do the whole site. So, it's a different way of doing it, but I think we are still getting at the guy, the developer, or the woman wants to just go out and clear the site we are saying that's not legal. Ms. Apple: Well, I guess one of the things that I envision is, you know we see how many developments are coming through at each meeting and I'm, you know, envisioning 12 developments going on at one time, and something that Commissioner Powell touched on i } earlier-you know, these site Inventories are going to be great, tree inventories--but do we really have people enough to be running around checking and making sure that, you know, this tree is still here and that tree is still there. And without some type of, I don't know, the permit being required would at least give a paper record of something. Anything you can do to make me feet better about all those developments and a few people out there trying to keep track of them. Mr. Hill: I'll tell you something though, to think that an inspector is going to be able to go out onto a site and find an individual tree and make sure that it's preserved can be very difficult. Because all of the sudden when all this construction starts taking place you start to lose your benchmarks. s Ms. Apple: That's my concern, ' Mr. Hill: OK? And what I art saying is that, if you have limits of clearing and grading and maybe we can put it in here that you have to flag it off with some plastic !lagging so that you can see the general line of demarcation--that's a lot easier for an inspector to catch than it is to try and catch individual trees. • Ms. Apple: Thank you. O Chairperson Scheru; Thank you. At this time we normally take a break and I would ask Commissioner Engelbrecht if it's a quick question or do we need to come back and start with you? 25 Kd 32 x~❑ e o Planning and Zoning Minutes January28,1998 Page 25 Mr. Englebrecht: I'll just wait; l have two or three. " Chairperson Schertz. Okay, at this time we will take a ten-minute break and start again at 7:15. Thank you. Chairperson Schertz: I'd like to reconvene. We are in process of reviewing the landscape ordinance. We are conducting a public hearing. We have closed it. We are now discussing with Mr. Hill, our Planning and Zoning Director and the Commissioners. We have a couple of Commissioners who still have questions, and at this time I would call on Commissioner Engelbrecht, please. Mr. Engelbrecht: First off 1 really appreciated those continents that you began this last little presentation with regard to what's not in the ordinance and what is. I think that was real valuable. Mr. Hill: Commissioner Engelbrecht, you asked for a copy of that list and 1 put the matrix that you have In your packet up on the screen. And if you look at every place where there is a box that is empty, under, there's Irrigation items, we say street trees is a reserved section for the future, alternative compliance, innovative design credits, tree removal permits, the empty boxes, those are the same items on that list that you asked for. We can still make the list for you but 1 wanted to let you know that you do have, where you see voids.,..... Mr. Engelbrecht: Where we have voids under proposed ordinance, Mr. Hill: We gave you a color version of that in your packet, 1 believe, Oh, I'm sorry we haven't given them to you yet. Mr. Engelbrecht: 1 was going to say, I'm not aware of those. Mr. Hill,, That explains that part of it. Mr. Englebrecht: Thank you. OK, I'll ...does the, let me start out with this question. The tree • inventory and landscape plan and all those sorts of things are going to be going through the DRC. Mr. Hill: Well, the... Mr. Engelbrecht: the Development Review Committee? • Mr• Hill: Well, the tree Inventory is something that will probably just go through planning staff, • and we will clear that if we need some help from inspections and code enforcement to verify. C That would be how that would be handled. The landscape plan would go through DRC and then / the plot plan would typically be handled at the inspection and code enforcement level. So when 75 x~ 32 x~❑ 0 Planning and Zoning Minutes January 28, 1998 Page 26 they go in for a building permit, that would be with the inspections staff. ` Mr. Engelbrecht: Okay, and I ask that because of the issue that you mentioned earlier, innovative design credits, you had pointed out that we have no system to sort of facilitate that at all. My concern is that, over time knowledge changes and as a result of that design criteria and ideas about design change, and if someone came in with an alternative design. they would have to come in for a, some sort of a special permit other than.... they wouldn't be allowed to just to go to the DRC. The DRC couldn't approve it as 1 would read all this. Mr. Hill: The way that would typically work would be they would have to apply for a variance I s think, Now, if you, and the reason 1 don't have alte ve compliance in here is that if, some cities have alternative compliance, but it requires some kind of discretionary review by, say the Planning and Zoning or City Council the only thing that i can say is that a variance pretty much does the same thing. And the only time it really makes sense to have alternative compliance is if you are going to give some discretion to an administrative person, like a department director. And I don't have a problem vrith that, except that it's actually taking some power away from your regulations and fousting it on to an individual. Mr. Engelbrecht: Yes. It puts a certain burden on the staff person if it turns out that the political structure, the powers that be, don't care for their decision making. Mr. Hill; And again, I don't have a problem with that if they enter into that process voluntarily. I just as soon they go variance, And if we find that we are getting enough variances where there is something wrong with our ordinance , then it's time to fix the ordinance blr. Engelbrecht: Right. OK. The, do you perceive the street tree requirement coming rapidly behind this ordinance and where do we stand in regards to that relation to this particular.,,? Mr. Hill: My feeling is that it is going to become a part of a comprehensive plan. We are going to, at least we have proposed so far, and met with some favorable comments from City Council, to actually have a chapter in the comprehensive plan that we call The Street. In there we are going to figure out how to position all our elements, we are going to look at our pavement widths to see if we can narrow them up, spend a little less money, reserve money for bike lane, or land for bike lanes or street trees or whatever wr need to do. But we also have all kinds of telecommunications pressure to use that right away, franchisees. So the whole, we want the whole thing together. And I think that there would be, I would envision that there would be a recommendation to amend the landscape ordinance if we have, if we find that we have room,for street trees, and I think we will want to amend the landscape ordinance and actually put that into the implementation strategy for the comprehensive plan. So we are talking more than a year f from now, the way the current schedule stands. Hopefully we can move it up, but we'll see. 0 Mr. Engelbrecht: I guess then my comment would be that in that Intervening period, if we find very many new developments that come In without, with minimal or no street yard landscaping, l / think we are going to see some public outcry because that was, I still think, one of things that 1 s AUMM 0 n .'?iwEiSY Planning and Zoning Minutes January 28,1998 rr Page 27 1. drove, has driven all of this for quite sometime. Now, to the extent of putting the parking lot in the front it's going to sort of take care of itself because there is going to have to be screening and that sort of thing required. Mr. Hill: I think one of the things we will report to Council is that there are concerns that having some, some kind of curbside landscaping is not really ensured in this ordinance. 1 think that is probably a correct statement to make. OK? I have a feeling 95% of the time you are going to get it, but there is always something that is going to come up that is going to defy your abilities to do a 100% ordinance. Mr. Engelbrecht: The issue of irrigation in this particular ordinance has no requirement for any form of irrigation whatsoever. I recognize the issue of spray irrigation, or whatever, is mostly lost through evaporation. But there are as you have already mentioned, other technologies that are readily available • underground drip irrigation, and those sort of things which minimize evaporation, loss of water but at the same time helps to ensure some moisture to those plants. I guess, my question is, I'm not sure what drove this, what drove our concern, our desire to eliminate that completely? Mr. Hill: I think that what we're finding is that, and if we need to add it, I think we will and that's why I wanted to bring it up. That was not an easy discussion. I'm not even sure that we { had an agreement within planning staff. The expense of it was really I think the primary factor. 1 think that there are very reasonably priced systems, but you have to have, you need water- controlling mechanisms if you want automatic irrigation. I think that there has not been, at least from staff perspective, a whole lot of research that we have done on that yet. I have a feeling that we are going to have to probably bone up on that and be prepared to answer some costs questions as we head toward Council. Again, I know for a fact that 1 had a property where 1 was going to pick up some laser perforated PVC, because one thing about bleeder hoses is that it could be j willfully inconsistent. But there was some, there's laser perforated PVC that I was going to put around the entire foundation of my house that I owned previously that was about a footprint of 2,400 square feet and it was going to cost me $400. Is that reasonable to expect? I guess we could put that, I have no problems putting it in, I just wanted to raise that as an issue that right now, it's not in there. Obviously there's an opinion, Mr, Cooper stated that he's concerned water be there, at least for the early years of the life or the tree, I'm not going to say that I • disagree with that at all. Mr, Engelbrecht: Well, as I see it, the potcntlal here is and it may be worth at least attempting under the current ordinance standard but it would seem to me the other costs are going to be home by the City in the event that over that first, particularly, three years we see a lot of dying plants and we, in essence, have to field our inspection and force to ensure that those are • replanted. It has been my experience, at least in some areas around the city, I don't think that's O • been done. I think the vegetation has been allowed to die and nothing has been done to see that it has been put back in place, Pars of that is due to the fact that it's costly to rlo that, for the City, C / Mr. flit!: Would you care to distinguish at all between existing and new trees as far as your In 32 X I Y 0 o • I i Planning and Zoning Minutes January 28,1998 Page 28 } feelings about irrigation? Y Mr. Englebrecht: Oh, I think that it's the new vegetation that's going to... Mr. Hill: Ijust wanted to clarify. Mr. Engelbrecht: Yes. No,1 think it's new vegetation that's going to have the, it would seem to me, we're going to have the biggest problem with. Now, maybe it will be fine. Again, if we have a year of heavy development followed by a year or two a heavy drought, we could be in some serious ;rouble as a city trying to get out there and see that all those materials are replaced. Another question 1 have is to do with, as I see it, we have used the term urban forest as a concept which to me suggests, and I have nothing wrong with that, I kind of like that idea, which suggests a mix of vegetation. A forest to me is quite a variety of items, but we have no k requirement that the developer mix, let's just use the example trees, so that we could put all of one variety on their property and, in essence, you could wind up with a whole street full of, I don't know that that would happen, but a whole street full of a single variety of tree brings about two problems as I see it. One, it certainly, I don't think, goes along with the concept of a forest and secondly, we're exposed to the risks down the road, I think as Mr. Cooper mentioned, if some disease comes along, particularly for that variety, we can see a whole area wiped out pretty quickly. And I don't whether that was brought up or not, but it would seem to me that we might want to consider some mix on it Mr. Hill: We will add that to our list of issues that I think we need to... Mr. Engeibrecht: And I just wanted to, 1 guess, echo one of the comments earlier • Section 4, this whole business of food production, nurseries and farms. I'm assuming that's addressing land that's in agricultural use, generally or is zoned agricultural, or that sort of thing. Mr. Hill: Not particularly zoned agricultural, but actively used for agricultural purposes or livestock, ranching. Mr. Engelbrecht: Okay. 1 sort of agree. I think we need a little bit better terminology there • Mr, Hill: Okay. Mr. Engelbrecht: And I guess one final question, on page 4 at the top of the page, there was a 25°ie cut off that was the amount, the figure used to determine whether the ordinance was kicked into effect in the event of remodeling or redevelopment. Any particular reason we chose 25%7 • Mr. Hill: It's arbitrary, but the general premise is, and I've seen this used in other ordinances, as • • a matter fact, a lot of triggering of ordinances for any kind of major remodeling used to, in many ordinances used to be based on a dollar amount. If it exceeded a certiin amount and it wasn't just landscaping it would be a whole bunch of other things. And and I think that many cities / have now steered clear of that and they now talk about the percentage of change to the gross :32 x 0 0 Planning and Zoning Minutes January 28, 1998 Page 29 floor area. And in this particular instance, because you are talking about site area, we are saying if you really start to kick around big changes of your parking lot or your paved services then it would be similarly effective. What we are really getting at is at what point and time does a remodel represent a significant change in the property. And you know you could go 30%, 50% 1 don't have a magic answer to that. Mr. Engelbrecht: This is just sort of what's been used as, by other cities? Mr. Hill: By my experience - yes. Mr. Engelbrecht: Okay. Okay. Thank you and that concludes all of my questions. Thank you. Chairperson Schertz: Thank you. 1 have a few questions and then we have some people after me that would like to ask, or explore further things. Number one, the Tree Preservation and Landscape Ordinance sheet that was handed outjust gets rave reviews from me. This simplifies more than anything that 1 could have ever read; it helps me clarify that we're not the only ones doing this. 1 mean i sit here and 1 look at, in particular,residevtial development and I go across that line and I list, l look at all those names of those cities and everyone of them has some tree restrictions or tree guidance, and I didn't know that. So I just wanted to encourage anyway we could to get this list out into people's hands because this is a new animal-1 don't think everybody has seen it and 1 think it would help with clarification. Mr. Ilill: Well, l think what we did was, this was in your packet last time except that we had not filled in what the proposed ordinance would have. And you can thank Nancy McBeth for that. Chairperson Schenz: I appreciate that. Mr. Hill: She did a very niccjob on it. Chairperson Schenz: It really is, because it's so nice. I noticed a couple of things, and I'm going to sound off on what Commissioner Engelbrecht was saying. Be nice. You know I'a setting here looking on page. on the first page and it goes underground Irrigation residential and underground irrigation non-residential I look at the cities that primarily care about trees in their • community. And it is pretty easy to see which tree I mean which cities they are because they have it marked every one. And every one of those cities require sonic kind of maintenance. I just wanted to take a minute and point that out that when you go across there, the cities that do care about uees are taking care of them. And I wrote early on and I never did mention it.but we've taken lengthy discussions previously that if we are going to have parks we are going to have to maintain them. We are going to have parks, how are we going to maintain them? And 1 • don't see that this is any different if we are going to have trees we are going to have to maintain C • them. I totally agree that we'll have a city that's not happy, and I wouldn't be happy if I was driving around and I'm seeing a bunch of dead trees. So, I am going to strongly recommend that C we look into maintenance somehow, you know I was even thinking that residential when / landscape people come to houses they even build little berms around trees trying to hold in the ' J 32 x 11 1 it I~ I I [ r 0 r Planning and Zoning Minutes January28,1998 Page 30 water. So I again I guess I'm not wanting, I'm sympathetic not wanting to spend a lot of money but I would like to know that every avenue has been exhausted that if we are going to go through ' with this that we have tried to maintain. I thirds we have said enough about it and that you are going to address it. Mr. Hill i guess the only question that I would like to ask is, if you want to give us a little idea of in terms of irrigation, differentiate between existing and existing trees to be oroserved and new plantings. And then if you look at here we are differentiating between residential and non. residential. If you want to give us a little more thought on that we'll carry that to Council Chairperson Schertz: That is a really good question, and I mean it may-that alone may be reason enough that we don't vote tonight or we postpone as you suggested earlier and bring it back so that you have an opportunity to explore some of this avenue and come back with some more suggestions. Because I let the other Commissioners speak for themselves, but off the top of my head, I don't have the answer to that. Mr. Hill: Okay. Chairperson Scheriz: I realty don't, except 1 just go back to, if we have parks we maintain them. If we are going to want trees we need to maintain them and I'll stop on that. Mr. Hill: We'll r search that. } Chairperson Schertz: A little note that I had, everybody has talked about everything just about in that packet you sent us except the process that I know will come before us and that is the appeal process. If you could take just a second, l think it is self•explamtory; but, everyone, could you look through the appeal process on page 8 quickly. Mr. Hill: Yes. First of all, it places the right to appeal with the property owner or the applicant. And that means that typically, if you are going to have an appeal, it is going to be with a decision 1 based upon the finding either on the landscape plan or on the plot plan. Because that is where an f approval decision is made. Okay, the appeal actually has to be made to the Planning and Zoning Commission and that would be handled by planning staff within 10 days of the action subject 10 • the complaint. And that is fairly, again, standard language in terms of having to act fairly quickly it is, 1 know right off the top of my head that's a similar time period for making some kind of appeal to the Sign Board of Appeals for a sign decision. Then it comes to the Planning and Zoning Commission and you make the decision here and that is where it stops. Chairperson Sehertz: Okay. O • Mr. Hill: Okay and it becomes part of the public record. Chairperson Schatz: I just, that is how I Interpreted it, but we had not-we have discussed so much and we haven't discussed that little piece of it, but that little piece of it I'm sure will come i r 9.5 10 32XIO • 0 Planning and Zoning Minutes January 28, 1998 rr Page 31 i before this Commission. I just wanted to make sure that everyone understood that. On the--- back to the list that we were given tonight-I recognized some of the names but on Fairfax and Fort Collins and the city in Maryland-were those cities selected for any particular reason other than they absolutely love trees and they are marked, or...? Mr. Hill: Well, I think they are known nationally. Chairperson Schertz: Okay. Mr. Hill: As models to go by-] mean they are created with their regulations and they were forerunners in efforts to, typically; quite honestly all of these are known not for just their landscape efforts but for their progressive planning on all fronts. Chairperson Schertz: Okay, well I appreciate that; I just, I knew, there was a reason but I didn't know exactly what it was. And my last comment is that I would like to make is, when I was reading this last night 1 just put on a developer hat and that's what I would like to ask you to do for just a second. Let's pretend that Southridge, for lack of a better development, has not yet been developed. Okay, and they go in and the developer begins the development and it goes through several owners, the RTC and different owners that have multiple builders in it. And ` when I read these guidelines-if I understand it correctly---thc 20 trees per acre if one lot has a bunch of trees and one lot doesn't have any then the lot that has a bunch can kind of be used to offset the lot that doesn't have any trees. And the reason that 1 brought up Southridge is because a portion of it is very treed and it's hilly and gorgeous and the other part is fine, but it doesn't have any trees at all, And so when they went to sell those lots they priced it accordingly. So if you have your developer hat on I'm trying to figure out if you don't have enough trees, then on which of those vacant lots are you going to put the trees? How are you going to access it? I'm going to assume you have walked that process through and I was just curious what the solution was? Mr. Hill: I think it's fairly flexible. The reason 1 say that is because we have had the benefit of seeing how some developers have looked at tree preservation and trees; it was very enlightening to watch how Oak Park Village kind of went through the assessment process. Quite honestly, what they are going to do, they are going to take their tree inventory and they are goirg to overlay basic infrastructure on their subdivision design. They are going to look to see how they are going to format their roads and their lots so they can take the best advantage of the existing trees-all right. But then they are going to show on that-as they go through here-they are going to develop a construction plan anyhow. They have to do it by law; so a with preliminary plat they are doing their inventory as they head into sub, the actual construction plan approval process that has to be conducted before final plat approval. They will be required to also go through this landscape plan process. That will go dovetail through with the DRC, because the 0 1 DRC is going to be looking at a lot of the engineering and utility placement and road placement t types of concerns. They will make a decision at some point to time to show their limits clearing / and grating and that will be shown on the landscape plan. That will establish from the / \ subdivision improvement standpoint where they will remove trees. And it may be because of J AANNIM - o Planning and Zoning Minutes January2g,1998 Page 32 water lines, sewer lines--whatever. Then they are going to make a decision on how many trees do we have left and where are we going to be looking; are we going to want to determine building pads at the time of the subdivision design. And they can put them on the landscape plan if they want to and if they do then the builders will have to comply with that building pad. If they don't' wart to, they can say, "We elect not to and we meet the ordinance by either the existing trees or by planting new trees," and then they hand it off, And they say, "Okay, builders, you gays come in now, and you start building." If they don't put building pads on the landscape plan then the individual home builders are going to have to come in and show that they are not taking out trees that are considered protected on the landscape plan; but if they are, they are going to have to show how they are still meeting that per-lot requirement. Chairperson Schertz: Okay, so 1 am going to compare that so no matter how many developers' hands that a subdivision goes through, once it has been platted and given our blessing, then that Is what it is. i Mr. Hill: Right. Chairperson Schertz: Unless the variance or an appeal process is gone through? Mr. Hill: Right, and all the way through-again, to address Commissioner Apple's concern-- i they're going to be asked to determine where they are going to need to disturb land and clear land, So, they can't just go in and clear-cut at any single point in time. Chairperson Scheru: OK. Thank you very much for your time, Commissioner Apple. Ms, Apple: Again, this is probably just a comment more than anything; but, back to what Commissioner Schertz was saying about this comparison, out of the 20 cities that are listed on here, there are only three that do not have a protected tree size. Most of them have considerably less protected tree size than we currently do, In the proposed plan, they would not have protected-can't seem to get that word down-tree size, I noticed that some of the cities have a 3-inch, 6-inch, 8-inch--ours was 10 and it's going to be nada, And i also noticed that out of the 20 cities, there are only i cities that don't require tree removal permit, Just for the benefit of the people that don't have this list to look at, I thought she brought up an important point that the • majority of these cities that, you know, are trying to do something, do have a protected tree size and do have tree removal permits. Just a comment Mr. Hill; You are right, and we have deviated from the norm by proposing this strategy. Ms. Apple: I just,[ just have this hard thing fa, really large old trees being replaced by sticks. It • : just concerns me. • • Mr. Hill: I understand. Chairperson Schertz: Is the reason that there Is deviation-are we trying to meet something half h I0 32X10 • v AMA" Planning and Zoning Minutes Janu ary 2 8, 199 8 Page 33 C way or are we trying not to be as strict or what is the thought process. Mr. Hill: Well, again, its going back to-it's stating the inverse. Instead of it saying you go out and show me the trees you want to temove, we are saying, so you know, it's like, I'm not going to even use an analogy. I stink at them anyway, because I think you have them anyway. Instead of saying these are the trees 1 want to remove, what we are saying is-because the problem with that is that you are constantly monitoring. You feel as though anytime anybody cuts down a tree, you got to g) out and put a violation on it. And what we are trying to get at is if you show us a good constructive reason why you need to remove trees, you can go ahead and do so. You are still going to have to have 20 trees per acre; but if you have more than 20 trees per acre and you show your limits of clearing and grading, and you don't need to take out all of the trees-we aren't going to let you clear cut. So we are kind of doing it a little inversely compared to what other cities do. And we are carrying with that the presumption that if you want to further add structural additions or if you want to clear or grade for some other reason, you are going to have to come back and say I want to exceed the limits of clearing and grading that 1 have on my landscape plan. So that's how the trees outside the construction activity area would remain intact. So you can't just go and bulldoze everything, That's the way we are trying to work it. Chairperson Scherta: And 1 agree with that theory, because I did build in SoulMdge and that's when the tree ordinance first came out and we tried to implement it. All the builders were, I f ( mean they were not happy. Because if there was a big one of those trees In the middle of where you knew a house had to go; that was the biggest waste of time to have to go down and get a tree r permit removal and then wait for them to come out and wait to get permission, Time is money and I'm going to tell you I think that is the reason that it's started out strong and gotten weak and just kind of disappeared because there were so many complaints. So, I'm just sharing that because I live l that so I agree with you. Mr. Ilill: The other thing that helps us is that if we require the landscape plan at the time that we arc also going through the construction plan process, we get a chance to see the grading plans. And that really gives you an indication of where disturbance is required. Because if you see where somebody wants to clear a huge area but they are only showing changed contours very A ; close to the building, we are going to start saying wait a minute if you really need to clear that much in order to grade within the limits of this specific area, and if there are trees in there, those • trees would then be really protected. So, I think that we are not directly requiring tree removal permits and we are not declaring protected tees-what we are saying is we are orolecting areas that don't necessarily need to be disturbed-which other cities don't do. Ms. Apple: Then I would like to see if maybe the majority of the cities on your comparison--do you know-require some certainty that there is a protected-gosh, still having probleins with protected-protected tree size In, then, you know, work on variances due to a particular problem. * • Or in the case of putting up a structure in a particular place, maybe work on those, one protected tree at a time, Mr. Hill: And that is the thing when a landscape-the term "protected tree" I think Is a 2~, - 10 32XIQ 0 Planning and Zoning Minutes January 28, 1998 Page 34 misleading indicator, okay? Because when we get a landscape plan after we've had an Inventory and it shows that certain trees are going to stay, they are protected trees. But we are making them Individually designate them as part of their construction process. And we are not just I saying "voila, every 6-inch tree magically becomes a protected tree." That's not what we are I doing. It's allowing them some flexibility to make a declaration as they design the site instead of saying all these trees are protected and you have to get a permit for every single one you remove. A little bit of difference, but.... Chairperson Scbertz: Thank you. Commissioner Oourdie? Ms, 0ourdie: Commissioner Sclieriz brought up a point that 1 think is ver/ valuable about dead tree removal, and being that this is a landscape ordinance means that we are looking for a visual quality within our community. Now do we address this situation? 1 mean, 1 see dead trees everywhere and I know for a fact that I spent $500 to have a tree cut down. How are we going to handle this in this way being that w e have an urban forest which means death Is going to occur, Should there be a place in this to dictate how we should take care of trees that have passed on? Mr. Hill; My assumption has always been that the removal of a dead tree is the responsibility of the property owner. If you have a dead tree, and it falls onto someone else's property and causes damage, then you are liable and other than that we really haven't done much. Obviously, there is nothing in the ordinance about that. In terms of the visual aspects, and being able to make somebody take a tree down I'm not sure. Obviously again it is not in there, but we can put that down as an issue. Nis, Oourdie: 1 was just wondering because I drive by Southridge Estates and there are 3 or 4 dead trees, alter 2 years, destruction is going to happen and they have just been sitting there. Although, the other-the lower shrubs everything-looks great; but the tree just sits there, and 1 keep wondering when are they going to cut it down, which I think they are never going to do it, because it's so costly. Mr. Hill: We will check Into it and see-at least for that particular example-why it Is that there is a great deal of incentive from any property owner's standpoint. But if there are some particular situations that we need to check out, we will do that, Ms. dourdie: I was Just wondering if it was just overall? Mr. Hill: If it's not really Ms. dourdie: Right. It doesn't mention that if there is any legal ness to it, which I don't think there, is. But the visual quality needs to be addressed. 1f we are going to have death among the ! ! trees, if we have an urban forest, we are going to have something we are going to have to deal with down the road. 1 I Mr. Hill: Yeah. 2r) 10 32JO , 0 I Planning and Zoning Minutes January 28,1998 r Page 35 l Chairperson Schertz: And it may be an educational-1 don't mean to interrupt but-it may be an educational process. Like you said, you know that there are several reasons that that dead tree should come down. Mr. Hill: Right. Chairperson Schertz: Okay, if we are going to become an urban forest maybe what we need to do Is run some articles and explain why it is that you do need to remove it. And the second thing, could 1 have staff then contact one of these cities that is supposed to be an example of what we are following as to what they do? Mr. Hill: With regard to dead trees? Chairperson Schertz; Especially, I guess I'm not as worried about the citizens as I am even- maybe I shouldn't be maybe-like an Alberwrt's (something like that) if they put in a row of trees and they are all I mean.,, I'm just curious. Mr. Hill: There is another part to this, and I guess I'm not thinking it all the way through, if a I tree is dead and it's a tree that is Indicated as needed to comply with an ordinance, if an inspector sees it, they are going to say that you got to replace it. So. Nit, Powell: Having to replace it and having to tear it down are two diiftrent things. Mr. [lilt: Okay. Chairperson Schertz: Yes. Mr. Powell: You could replace over here , You still have the dead tree here and the cost of taking it down may be something they don't want to do. Sir. Hill: Okay, good point. Chairperson Schertr Too much wisdom. Mr. Hill: I think that also, talking about educational. One of the things that I think that we,are absolutely going to have to do Is that we need a companion document. And I've been talking with Cecile Carson with Keep Denton Beautiful and we're checking in, trying to see if there's ♦ any way we can work with the 1 ree Board and maybe some other experts and put together some • kind of a brochure that's available that gives a little bit of advice on how to make the best of your Investment. And that would be helpful, not just for developers but also for folks who are C interested in landscaping their property. _ 25 K101 32XIO MR MM =iimm,E%&NjULX1]jALM% +t a 0 Wr#n Planning and Zoning Minutes lanuary28,1998 Page 36 Chairperson Schertz: At this time, there are no more discussion questions from the Commissioners. I think I speak for everyone in telling. Dave that staff has come a long, long way. I mean this is shaping up and I know you have a little bit more to go. But I think all of us are pleased with the directness, the length of the document, the specifics given and at least the awareness of what we're really getting into. You are to be commended and so is your staff. And at this time, I would like you to give us, help us with instructions as to what the Council is looking for from us right now. Mr. Hill: The way the schedule works right now-and again. I think we have some circumstances that you might want to consider simply because you only received the ordinance yesterday. The ordinance is going to be discussed at work session by City Council on February 10. We will take what concerns we've heard today and we will try to do some research to elaborate when we go to that work session. But we have an opportunity between the work session on the 10' and the public hearing on the 17". There will be a. I think, a Planning and Zoning meeting on the Ill which is the day after the work session if you would like us to come back to you with the information that we brought to the work session and if you would like to add further comments, we will make them available as part of the staff presentation at the public hearing on the 17' to City Council. So, if you would like to remain Involved, there Is an avenue to do that However, one way or another, I guess, what I would like to see Is at least some kind of conditional recommendation tonight that we can take to the work session. Then, if you would like to elaborate on February 1 I' if you would like to have it back on the agenda, we wilt work with you to get your message up to the City Council members. Chairperson Schertz; All right, Thank you. So, what I hear-let's take it one step at a time. But, the first step is you want some kind of recommendation, with some kind of reference to some of the items we'd like to have addressed. Air, Hill; Yes, Chairperson Schcrtc Is that correct? I had asked Mr. Donaldson previously to take some notes, and he has been feverishly writing as we have been discussing and talking. And he has pages of notes. So, l believe he's going to-what I asked him to do, because I had anticipated this, is to keep notes and as he kept hearing recurring things that we are all saying or items that have been • brought up was to address them in hope that it will help expedite some type of recommendation to Council, and I think that is where we're going is we either-we either like the way it Is or we don't like it at all. Or, we're leaning towards this, but we would like to make some recommendations. And with that, I will let Mr. Donaldson, hopefully, condense what we've all said so we can move on. N' Mr. Donaldson: I would characterize th£s as a laundry list of items discussed this evening. The N N pages may be mPny, but they are small pages. It shouldn't be too bad. We talked about setting some sort of required planting, street yards so that this new ordinance Is a deviation from the existing one. You may want to consider that In your recommendations and the second two items on this page. The impact on strip development, particularly with parking lot landscaping, we MORE ?x10 3zx , i C Planning and Zoning Minutes January 28, 1998 Page 37 talked about. We talked about soils and the need to conserve the native soils, and Mr. Cooper mentioned perhaps establishing an 18-inch topsoil base as some sort of a minimum requirement. " We talked about the water for new plantings, in particular of trees for a three-ytcr critical period. We talked about the desire to have a mix of trees within what we determine urban forest. The 10% rule as mentioned was that no single species should be greater than 109'ye of the total. We talked about various tree protection measures that are in the ordinance. We talked about cost benefits of trees. We talked about whether the ordinance would apply to new versus expanded development and we learned that it would apply to all new development, residential and commercial, and some commercial remodeling triggered by a 250,4 expansion as drefled. We talked about the impact of the new ordinance on staff time and how it compared to existing demands, We talked about the cost of the ordinance to developers both in terms of preparing plans, for submittal to the City, as well as the costs of increased landscaping requirements. We expect that concern will develop about whether protection of trees is adequate. We talked about the penalties-where the dollars would go if we collected some. We talked about particular impact on car dealers and others who perhaps areas for display. And we kind of characterized tree preservation in terms of "carrots" for "sticks" with the proposed ordinance being r'ety oriented towards "carrots.", other ordinances being oriented towards "sticks,"-there may be a balance. We talked about the street trees; the reservation in the current ordinance for additional requirements with the comprehensive planning until such Is completed. We talked about l required irrigation, long-term maintenance, and what do we do about dead trees-if that refreshes your memory on topics that were discussed this evening. Chairperson Schertz: 1 appreciate that, and if I did not, I want to close the public hearing, and at this time, I would ask the Commissioners for their input to make recommendation to Council, please. Commissioner Gourdie. Ms. Gourdie: I would like to see us recommend the landscape, tree preservation landscape ordinance with all included in the situation so that they can discuss it and have more Input and then have it come to us on the 1 I" so we can understand how they would like to see it go. What we have working together on this situation if we're on opposite ends and see if we can come together or stay together as we should be. That's what I would like to see happen, ~A Chairperson Schertz: Thank you. Commissioner Engelbrecht. Mr. Engelbrecht: I think you have said in gener" view this ordinance favorably. very favorably in terms of what it's trying to do and the way it's going about it. 1 would like to put In one point here. Particularly, Mr. Cooper here as we3-4 had asked-I was the one who asked about the irrigation requirements, particularly the non-residential Irrigation requirements. I Just want to say, 1 would like to ask staff and all of those who were involved In trees, to really • investigate if there's not some other possibilities that could be required of developers other than • • the current system of underground with all the pipes. I've done that. I know that's expensive and time consuming. and then there's a labor maintenance issue after the fact. Are there some other systems that research organlzations-A do M, etc. are looking at that would facilitate these, some additional; or ensure that tbey're going to get sufficient water without all this underground ~A 75 ~ 10 32 X I O • :rsrm~a Planning and Zoning Minutes January 28, 1998 Page 38 irrigation. 1 think they're going to need water, but I really think we need another system, t particularly given that we're requiring so much in parking lots, which is going to mean a tremendous amount of labor to put all this in--and then to maintain it under those asphalt or concrete lots. So, while I would like to see something, I'm not sure 1'd like to see what I know is the current level of technology. Are there other things out there that we could promote and suggest? Thank you. Chairperson Schertz: Hopefully, with these three cities that are supposedly model citie" mean you never have to Invent the wheel when someone else has done it, and obviously they've had to tackle this and address and if it's the best thing they've come up with-the expensive method. Then we need to be told that, and we can make our decision accordingly. Hopefully, that will be something that wilt not require a lot of time, but just some phone calls. Commissioner Powell, please. Air. Powell: Thank you. 1 for o.te 1 like the concept, and 1 espedally like the "keep it simple" approach---real small. One thing that I just thought of-nobody has mentioned it. I can remember not too long ago, in the city of Denton where it was against the law to water your lawn on certain days of the week because of the drought situation. We live in a desert here. We have changed it with man-made lakes, and we have been lucky the past seven or eight years with the amount of rainfall, We still live in a desert or desert-type area-maybe not a true desert. But we have very little rainfall around here. If it hadn't been for these man-made lakes, you wouldn't have a Denton as we know it today. I'm not trying to make more out of this than it is, but if you're going to require watering, keep in mind the same City that requires watering may be turning it off later. 1 don't know if anybody has given that any thought. And I've lived here long enough to see that. And I've heard horror stories of when they were piping water here from the Red River, and it was too salty to drink. So, I don't know. I'm just throwing that out there. If you're going to require watering, somebody had better keep that in mind. Now, as to whether I vote for the ordinance, I'm going to say no. It's not because I don't personally appreciate the ordinance. But 1, for one, cannot vote for it because of the big, big government, big brother approach. I can't sit here and vote to tell somebody they have to have 20 trees per acre. I don't think it's any business of the City how many trees somebody's got per acre. I would love to have that. Personally, I've got that and maybe more. And 1 think, yes, trees provide a lot of value, but I don't think government has the right to do that to people. So, basically, I have to vote no on the ordinance. Thank you, Chairperson Schertz: I go along with Commissioner Powell. I certainly think he has made some valid points. And 1 talked with Nit. Donaldson this morning. I said what this reminds me of is when the seat belt law came into effect and everyone said the government didn't have the right to tell me whether to wear a seat belt or not and so we all complained and whatever and guess what, • they did and we do and we get tickets for it and it's maybe a bad analogy but we're, I had the same tnought process that Commissioner Powell did that we were going to get a bunch of complaints of telling people if you come to Denton, you're going to have to plant trees and, you (1 know, I went to one of the public hearings and the people were actually saying, "Well, if you 10 32XIO • 0 " I Planning and Zoning Minutes January 28,1998 Page 39 don't like it, don't come". 1 mean is that really the attitude, and is this what we are saying with this tree ordinance-if you don't like it, don't come, Is that what we want to communicate. So, l just wanted to share that-their thought process has certainly gone through my mind, and I think Commissioner Powell would like to add one comment. Mr. Powell: I have to say that that is true. 1 don't question whether the City has the legal right to do it. I, personally, believe that, lately, government has got the right to do anything they want. People's rights have seemed to have gore out the window. The constitution seems to be null and void. I don't question whether it would pass In court. 1 cannot vote for it personally. I'm not telling the rest of the people here what to do or how they should look at it. But, I can't vote to deny people's freedom. This has gone too far, Twenty trees per acre--any number of trees per acre--maybe they want lawn, as opposed to trees. It's more than 1 can stomach and I'm sorry if keep"beating a dead horse" here. Thank you. Chairman Schertz: No, We appreciate all opinions. Commissioner Engelbrecht. Mr. Engelbrecht: I just couldn't resist responding to Mr. Powell's comments. It would seem that the history of the United States, and now a history of development In the rest of the world, suggests that as development comes, the trees go. And we have 200 years' worth of history to I show that, in this country. And you can simply look at the rain forest in South America to see { that the very same thing is happening at a rate that is very alarming to those who are concerned with our overall environmental structure around the world. There is expert after expert who say we're going to have to have vegetation. 1 think the reason we see these ordinances Is because when we didn't have those ordinances, we didn't have any vegetation. And we can look at University Drive nerd see that. You can look at---and I've said It here before - you can look at developments in the last five years, What was the grocery chain that is now gone? We had a landscape ordinance, and we now have landscaping In front of those buildings. Other cities did not have landscape ordinances and they don't have any landscaping around those structures, And I think the people have said we want it, and we would like government to see that it's done, because no one else will see that's accomplished. Whether that number and quantity-where that goes is, obviously, always going to be a question. But the fact that they are there-we've M , put some requirement on, The rest of our community-1 think i s m hat our-{he majority of the folks have asked for. And it would appear that that's the case across the metroplex and around the country. 1 hank you. Chairperson Schertz: Thank you. Commissioner Apple. Ms. Apple: 1 guess I'm stuck somewhere herein the middle. I'm in favor of some aspects of the ordinance because I do think that we do need requirements for commercial building, eta to have an attractive and healthy view. But I'm a person; l will have to agree with Commissioner Powell • In a sense, because 1 am a person who moved from northeast Denton from a residential lot • crammed with trees and due to, you know, severe allergies have to find an acre and a half that only has six trees so that 1 could breathe. So I would hate to think that 1 would have to have you { know 20 acres whether I wanted I mean 20 trees whether I wanted them or not. So I'm kind of Ile somewhere in the middle. I'm In favor of an ordinance but 1 think there are seven) thins that i ~ 'f 32XIO • O Planning and Zoning Minutes January28, 1998 Page 40 } need to be looked at. r Chairperson Schertzt Thank you. There are no more requests to speak and I'll go back to what Commissioner Gourdie started out with, that 1 believe you discussed basically recommending it-looking at all the items that Mr. Donaldson had written down. And Commissioner Engelbrecht added, I believe, one to that list or clarified it. And 1 don't know if someone would like to make that motion or another one so that we can move forward. Then I believe Commissioner Gourdie alw said that we make that recommendation but that we also ask that it be brought back to us on our meeting following the work session of the Council. Ms. Gourdie: I move that we recommend the landscape ordinance with the tree preservation be passed on to the City Council for their input during the work session with the written notations by bit. Donaldson. And that it be brought back to us on February l is to understand where we stand with it. Mr. Engelbrecht: Second. Chairperson Schertz: The motion has been made by Commissioner Gourdie and the second by Commissioner Engelbrecht Is there any other further discussion? Seeing none. All in, Seeing none. We have, Thank you, we're now voting. It's been long already; we are now in our voting mode and if everyone would cast your vote, I would appreciate it. Voting is complete, and the results are 3 In favor and 2 opposed--with the 2 opposed being Commissioner Powell and Commissioner Ganzer. So with that motion, we will make that request to staff and appreciate your time and effort. Also, we would like to thank Mr. Cooper, I think you had some extremely-I had never thought about the soil until you brought it up-and that's an extremely important point, And having been a builder and knowing what people do with that soil when they move it, it could be very productive rattier than just tossed somewhere. So I would like to encourage you to slay, I'm sure you will-we won't let you go--stay involved and thank you for your time and effort. 15. LDR Estates.

LOOP 288, SUM 222 DENTON, TEXAS 782014618 9406 565-MM OR MM O 972-43,14062 The most dominant features in any landscape are its shade trees. They tower over all other plants and many times even the home itself. Establishing quality shade trees should be at the top of every homeowner's list of home improvement chores. Nothing makes a neighborhood like its trees. Find a street of hardy oaks and you will find a neighborhood that holds its prop-arty values above the average. Trees beautify the home and business, cut cooling costs, reduce water bills, cleanse and freshen the air we breathe and reduce noise, heat and glare of the city. The kind of tree you select has more bearing on Its long term health and performance than anything else you will do. Our most desirable trees exhibit strong branching, moderately fast growth rates, good resistance to pests and are well suited to our soils and climate. The top shade trees to plant in Denton County include from tallest to shortest on (good saes): pecan (807; shumard oak (701; sweetgum (6011 bur oak (60')1 baldcypress (60'); live oak (50'; chinquapin oak (50'}1 fruitless and thornless Osage orange, e. g. 'Park' (507; Texas ash (401; Chinese pistache (401; lacebark elm, 'Drake' (30')1 and common persimmon (301. For evergreen windbreak trees, our best choices Include live oak (50'); Austrian pine (4011 eastern red cedar, the "sneezeless' cultivar,'Caneartil' (401); and Japanese black pine (301. All of the above Its trees can be planted In any soil exce:,st sweetgum, Chinese plstache and Austrian pine which should be reserved for acidic soils. When you get to the nursery, selecting which tree to buy Is simple but • critically important. Use the same care you use when buying produce. Expect the same quality. inspect the trunk closely.. Avoid trees with missing, cut, leaking, bruised or discolored bark. Look for strong shoot development with smooth, straight wood and large buds and leaves. Avoid trees with weak, broken, scarred, scalely or cankered branches. Container grown trees cost more than geld grown trees because they cost more to produce. Container grown trees are usually worth the extra price • though because they establish more quickly than dug trees. The advantage of dug trees Is that you can buy a larger tree for the same money. Regardless of the type, the root ball to trunk diameter ratio should be 10:1 or greater. Extension programs serve people of ar ages regardless of socioeconomic level nee, color, sex, re0gion, dsatylity, or national origin. The Teat AAM Universky System, U S. Oepariment of Agrkutture, sM the County Commissionea Courts o1Texas Cooperating r ~Q 32 x~ s 0 Soil preparation Is the first key to establishin trees. The hole should be dug no deeper than the root ball so that the root ball rests on firm, undisturbed soil and will not sink or settle when the tree is watered in. The hole may be dug as wide as you would like, Backfill the bole with a 2:1 r ratio of native soil to well-rotted compost. The volume of soil you amend around the root ball depends on how much compost you can afford to buy or produce but typically six to twelve Inches around the root ball win get the roots off to a good start. Poor soil drainage is one of the most common causes of tree losses during the first year or two after planting, If you have a poorly drained site, you can significantly improve the tree's chances of survival If you plant the root ball half In and half out of the ground. Cover the top half of the root ball with amended soil and gradually slope away. O over. Trees nce you have the tree planted, stake it upright If the tree is likely to blow amended soils areas sunder-sized root ubject to wind-throw and should be staked, Lo sheavil ely tie the trunk two-thirds the way up the trunk. Use wide bands of soft, flexible material such as strips of old tare inner tube, to loop around the trunk and tie to two stakes sunk straight up and down parallel to the trunk and a the trunk to flex as djacent to the outside edge of the root ball. Provide enough play to allow Allowing playa and flex In the hunk makes before trunk stronger when ttarn over. he stake Is removed. Remove the stakes after two or three years. After the tree Is planted and staked, apply a heavy, three to four inch layer of organic mulch. This will help keep the soil moist to the surface and prevent th the e soil from cracking at the surface. Soil mulches make the soil cooler in summer des to ekillwinter weeds and gras grasses Including competition turf weeds. that grows up In the mulch, Do not spray herbicide on green parts of the tree. The trunks of newly planted trees and young trees with thin, smooth bark should be wrapped from the ground up to the first limb from November through February to prevent freeze damage and from June through August can protect them from sun scald. Remove the trunk wrappss at the beginning of each season and replace with fresh ones at the beginning of the next. Trunk wraps are only helpful for the first year or two of establishment. Added trunk protection from string trimmers and runaway lawn mowers should be provided at the base of each tree. Use specially designed heavy rubber tree trunk guards, Flimsy plastic tree guards do not work, Flexible drain pipe works very well as a tree guard material. Simply cut flinch flex drain pipe into 8.12 Inch lengths and sht them up one side. These can then be easily slipped over the trunk for quite an effective tree trunk guard, %mering is critical to the survival of newly planted trees. Even with a heavy 32 • 0 l mulch, trees should not go longer than ten days without rainfall or irrigation during their first two years of establishment Over watering can be Just as deadly however and trees should not be watered more often than twice a week. Watering deeply once a week In the absence of rain during the hottest days of summer is probably about right for any tree in any soli If the tree is heavily mulched. As with any plant, you cannot drown trees by applying too much water, you can only drown them by applying water too often. When you water, water deeply. There Is a great debate about whether or not to apply fertilizer to newly planted trees. The truth is that if you have a container grown tree, it has been fertilized since it was a pup and likes it pretty good, so keep It up. If you have a dug tree, it will be growing roots soon and when It does, you want It to have access to fertilizer. The notion that the roots of newly planted trees are too tender for fertilizer is wrong because feeder roots on any aged tree only feed for the first two weeks or so of their life before they become too woody to feed. The problem with fertilizers occurs when people either apply too much fertilizer or they don't keep the trees watered. A general rule of thumb for fertilizing trees Is to use a complete balanced fertillzer such as 10.10.10 applied under the tree in a circular pattern with a diameter equal to the height of the tree at the rate of one cu per Inch in trunk diameter in March, April, and May, Fertilized trees should not be allowed to go completely dry before being watered. But remember, don't water too otttenl Pest management requirements should be few if you have planted a recommended tree species. However, any tree, regardless of age, Is highly susceptible to attack by borers during the first two years of establishment During the first two summers after planting, apply a borer spray contaWn~t chlorpyrifos or lindane to the trunk from the ground up through the scaffold limbs once every four to six weeks from April through September. Young tree training Is very helpful In building a strong, well-branched tree. Although some tree species have naturally strong branching habits almost any tree will benefit from selective limb thinning in the early years of its life. The primary and Incontrovertible rule for young tree pruni ng Is simple, • eliminate forks. Forks always result in narrow branch angles w&76 are weak by nature. Where more than one limb arises from a single node, a fork develops. Remove all but one of the limbs at a node, Leave the limb that Is ggrowing in the direction you want It to grow. If the limb you leave is also the fiealthfest and the straightest of the limbs, so much the better. • You can select the limbs you want to grow during the growln season rather than wait for them to grow and then cutting them off In the ormant season. By going out and looking at your trees every couple of weeks you can see how l the branches are developing. If you see two buds breaking from the same node, stop one of them by removing the growing tip. The shoot you leave in 32 x In • 0 will take the sap intended for both and will grow twice as fast. As the tree grows, allow It to develop a "trashy trunk". Remove only the lowest one-third of the limbs arising from the trunk. Using this method, called the "trashy trunk" method, when the tree is eighteen feet tall, the ' lowest limbs will be six feet off the ground. Most people want their trees to have their lowest branches a minlmum of five to seven feet off the ground to facilitate foot traffic so that is when you would stop removing limbs from the trunk. The trashy trunk method delays the 'tree form" appearance of the tree but It is very Important for developing strength in the trunk. Trees not developed with a trashy trunk tend to lean with the prevailing wind because the trunk was weak and whippy in Its early years of development Lifting the canopy of mature trees even higher than the typical five to seven feet is often desirable. The foliage of many trees is so dense that the home cannot be seen for the forest Trees are planted and it takes so long for them to grow we do not realize they have begun to screen the home from view. Sometimes a whole new perspective on the home can be gained by removing the lowest limbs so you can see the home under the trees, The lowest limbs are the weakest limbs on the tree. Because the light at the lowest levels of the tree canopy Is of lowest intensity, the lowest limbs may actually be consumingg more energy than they are producing for the tree. Pruning the lowest lfmbs usually results in a more vigorous tree with stronger peripheral growth. A trees, third benefit of pruning the lowest limbs is that vegetation under the exhibitinge lower gorthan gthey once displayed may simply be suffering from low light Intensity, This is especially common in turf, even St Augustine. Removal of dead, dying, damaged or diseased wood Is probably the most common reason to prune mature trees. Limbs the over time from many causes. Periodic removal of weak and damaged wood improves the physical appearance, lowers the safety hazard of falling limbs and helps maintain the structural Integrity of the tree, " Trees leaves fag to the ground each year and mulch the roots. Soil microbes compost the leaves and release the minerals to the tree roots, This Is the natural feeding cycle for trees. Don't bag you leaves and send them to the landfill. Shred them down Into the turf with your lawn mower where they will break down Into soil. If there are too many leaves, shred and bag them with your lawn mower and use them as mulch under your trees and shrubs. Trees provide so many environmental benefits It Is a great accomplishment 0 to establish one. Although the establishment requirements described here may seem rigorous, they are intended to get the beat possible trees off to the best possible start with the greatest possible success so we may an enjoy the best possible urban forest throughout the years to come. in 37xIa t 0 ' I I „ l Texas Agricultural Extension Service The Texas A&M University System r NATIVE PLANTS TO USE FOR ENHANCING WILDLIFE HABITAT by John Cooper, Denton County Extenelon Horticulturist WM scaping Is the practice of creating wildlife habitat In the urban landscape.

A commercial project and a residential project were selected for this comparison. The charts Indicate oomparsons for The amount of landscaping the project actually provided. I What the current ordinance requires, ♦ What the requirement for gas projects would be 9 the proposed ordinance were In effect, Note that this comparison Indicates only the amount of trees that were preserved at the Gme the development was approved. Note that on both projects, the amount of trees required by the proposed ordinance could have been sallsilied by the ftlsting tree population on those styes. This chart also oompapes the pervious and Impervious surface requirements of the current and proposed ordinances end as provided by the developments. Consider that downtown, troy urban conditions, typically allow 00 to 100 percent paved and bulll Impervious surfaces. The current ordinance allows 95 percent knpervlous surface coverage In any development of r the City other than residential, where currently, 100 percent irnpervicus surface would be allayed. N Planning Commisslon requested we look at the Alberlaon's on University as another comparison. Included In this section are two sila plans indicating the current conditions and another plan which indicates the effect the proposed ordinance would have on the site. In this particular case, because ftedson's chose to over-park their site by 116 parking spaces, we were able to gamer the 20 percent open space and provide for the required trees by a shift In the structure and oompleley revising the parking area. Two addillonal drawings are provided which Indicate typical aingle•famiy lots under current zoning ordinanoa requirements and a non-ypleal smaller lot not currently atloweel, This plan 0 indicates the quantity of trees required In proportion to thew lots.

Definitions Clearing. An Intentional act to cut down, remove all or a substantial part of, or damage a tree or other vegetation that will cause the tree or other vegetation to decline and/or die. Clearing Is defined to include, but not be limited to, chemical, physical, compaction, or grading damage. Clear-cutting Is a clearing activity conducted over an entire lot. Critical Roof Zone.- A circular rglon measured outward from a tree trunk representing the essential area of the roots that must be maintained or protected for the tree's survival. A tree's critical root zone Is measured as one foot of radial distance outward from the trunk for every Inch of tree OBH, and may be no less than a radius of eight (8) feet. DOH. Diameter-ail-breast-height (DBH) Is the tree trunk diameter measured in Inches at a height of 4.6 feet above ground level. If a tree splits Into multiple trunks below the A% feet level, DBH will be defnncd as the sum of each individual trunk measured at 4Y, feet above ground level, or the single trunk at its most narrow dimension, whichever Is greater, Director: The City of Denton Director of Planning and Developmont, or she Director's designee. Drfpllne: The area beneath the canopy of a tree defined by a vertical line extending from the outermost edges 1 of the tree branches to the ground, Erosion: The detachment and movement of soil or rock fragments, or the wearing away of the land surface by water, wind, Ice, or gravity, Grading: The mechanical cr physical act of disturbing, moving, removing, transferring, or redistributing soil or earthen surfaces. Gross Lot Area: An area under public or private property ownership, whose lot lines are described by plat or deed. Ground Cover: Low growing plants, vines, or grasses that form dense, extensive growth, and have a positive effect against soil erosion and soil moisture loss, impervious Surface: A surface that has been compacted or covered with a layer of material so that It is highly resistant to infiltration by water. Limits of Clearing end Grodfng: The boundaries of that area of land Wentifled In a landscape plan to be subject to soil disturbance or cleared of trees and other vegetation in conjunction with a proposed development or land use. Live Plant Materiels: 'live" plant material, including grasses, annuals, perenntals, bulbs, groundoover, shrubs, and frees are botanical plants that are nourished through the processes of air, water, and toll nutrients. Plant materials such as, plastic, fibrous, sltk or other nondlve materials are not oonsWered live` plant materials. j Outdoor Storage Ar.a: Any area that contains trash cotiecllon eraas or dumpsler refuse containers; outdoor loading and urloading spaces; docks or outdoor shipping and recelving areas; outdoor storage of bulk J14 materials and /or parts; or areas regularly used for outdoor repair, outdoor storage areas of service stetbns, motor vehicle desters, or Inspection stations.

Lighting Ordinance B. Thoroughfare Corridor Overlay District C. Affordable Housing Research BACKGROUND City staff has provided a progress update of scheduled Denton Plan activities on a regular basis, and Council members have asked that additional items be added within recent weeks. The revised schedule (attached) has been drafted for City Council review, and will be revised as per the instructions received alter issue priorities and estimated times of completion have been discussed. UTIMATED SCHEDULE OF PROJECT The time frame for the Denton Plan is expected to extend to the end of 1999, as currently scheduled. Implementation, particularly with respect to major rewrites of subdivision and zoning regulations, will exacnd the timeframe even longer. The implementation items added are of shorter duration, and will be completed, at least on an interim basis, before the end of 1998. FRIOR ACTIONIREVI E1V The schedule has been reviewed periodically since summer 1997. The most recent review by City Council was in October 1997, wben the coordination of Comprehensive Plan and Development Impact Fee schedules were discussed. FISCAL INFORMATION The addition of the new schedule items will impact staffing priorities for the Planning and Development Department. Staff has begun the process of developing a detailed tirrtclabie for the comprehensive plan with the intent to compress the estimated completion time, and the additional items are being programmed to avoid Interference with comprehensive plan efforts. • The Small Area Planning Program may experience a temporary slowdown during the summer and fall of 1998. At this time, staff does not feel that consultant services would be effective in • addressing schedule priorities. i 4. 25 32XID FXIiIWITS City of Denton Planning Activities do Timetable (last revised; February 4',1998) Respectfully Submitted: avid M.
