A public discussion of these legal matters would conflict with the duty of the City?s attorneys to the City Council under the Texas Disciplinary Rules of Professional Conduct of the State Bar of Texas or would jeopardize the City?s legal position in any administrative proceedings or potential litigation. nd Following the completion of the Closed Session, the Council will convene in a 2 Tuesday Session at which the following items will be considered: nd NOTE: A 2 Tuesday Session is used to explore matters of interest to one or more City Council Members or the City Manager for the purpose of giving staff direction into whether or not such matters should be placed on a future regular or special meeting of the Council for citizen input, City Council nd deliberation and formal City action. At a 2 Tuesday Session, the City Council generally receives informal and preliminary reports and information from City staff, officials, members of City committees, and the individual or organization proposing council action, if invited by City Council or City Manager to participate in the session. Participation by individuals and members of organizations invited to speak nd ceases when the Mayor announces the session is being closed to public input. Although 2 Tuesday Sessions are public , and citizens have a legal right to attend, they are not public , so citizens are not allowed to participate in the session unless invited to do so by the Mayor. Any citizen may supply to the City Council, prior to the beginning of the session, a written report regarding the citizen?s opinion on the matter being explored. Should the Council direct the matter be placed on a regular meeting agenda, the staff will generally prepare a final report defining the proposed action, which will be made available to all citizens prior to the regular meeting at which citizen input is sought. The purpose of this procedure is to allow citizens attending the regular meeting the opportunity to hear the views of their fellow citizens without having to attend two meetings. 1. Receive a report, hold a discussion and give staff direction regarding strategies for maintaining and revitalizing neighborhoods. 2. Receive a report, hold a discussion and provide staff direction concerning a Lawn and Landscape Irrigation and Water Waste Ordinance. 3. Receive a report and hold a discussion regarding the Water, Wastewater, and Solid Waste Forecasts.

AGENDA INFORMATION SHEET April 11, 2006 AGENDA DATE: Parks and Recreation Department, Neighborhood Services Division DEPARTMENT: Howard Martin, 349-8232 CM: SUBJECT Receive a report, hold a discussion and give staff direction regarding strategies for maintaining and revitalizing neighborhoods. BACKGROUND The City Council has been considering strategies for revitalizing neighborhoods since the fall of 2004. The Council has been interested in pursuing methods to improve the quality of housing and to affect the ratio of single family to multi-family units. Since then Council has directed staff to research and review methods and programs to achieve Council?s goal of improving Denton?s housing. To this end, in August 2005 Council adopted a comprehensive Multi-Family Residential Standards ordinance. The Multi-Family Residential Standards ordinance amended the Development Code by permitting multi-family developments under the following conditions: with a Specific Use Permit; or as part of a Mixed Use Development; or as part of a Master Plan Development, existing; or if the development received zoning approval allowing multi-family use within one year of the effective date of ordinance; or if allowed by a City Council approved neighborhood (small area) plan. As well, the ordinance made provisions for restrictions that include a development agreement and standards that establish a minimum level of development. In February 2006 Council directed staff to proceed with further strategies for revitalizing neighborhoods. In response the staff has prepared the following report. This report identifies possible policy and code changes to revitalize Denton neighborhoods. These possible policy and code changes include: adoption of the International Property Maintenance Code; conduct a property maintenance survey; establish a rental inspection program; and process for upgrading substandard housing. Concurrent with these policy and code changes are recommendations for Comprehensive Plan amendments, land use issues, and Fair Housing Standards issues. I. International Property Maintenance Code (IPMC) The IPMC will establish minimum structure/premises maintenance standards for the City of Denton. This review of the IPMC is a continuation of the comprehensive review of ordinances, procedures and programs related to property appearance and code enforcement. Proposed Ordinance On February 14, 2006, the City Council received a report from staff on the IPMC. At that meeting, Council directed staff to provide a more detailed comparative analysis of the IPMC with existing City of Denton codes pertaining to building and property maintenance. The purpose of the analysis is to determine if the City?s codes are consistent with the IPMC and what gaps, if any, exist in the City?s codes or the IPMC. Attached for your review is the code comparison (Exhibit 1). Three components are combined in the comparative analysis: 1. Comparison between the IPMC and the City of Denton, Code of Ordinances and Denton Development Code 2. Issues addressed in the Denton Development Code and the Code of Ordinances that are not addressed in the IPMC 3. Additional provisions to be considered not currently considered in either the IPMC or the Denton Code of Ordinances. The IPMC will establish the minimum standard for property maintenance and serves as the baseline tool for Code Enforcement and Building Inspection to address existing structures and premises. As a preventative tool, the IPMC will, in the long-term, aid in stabilizing and improving property values by correcting code issues at a much earlier stage. The enforcement of the IPMC should prevent more significant and costly repairs and rehabilitation, that sometimes occur at the city?s expense. Recommendation Staff recommendation is to move forward with the following process to adopt the IPMC. Ordinance Adoption Schedule & Process Public Input and Education The Neighborhood Services Division will schedule two public hearings related to the IPMC adoption. Both meetings will be publicized in the local newspaper and direct notification will be provided to stakeholders and organizations likely to be impacted by this change. Copies of the comparative analysis will be available for review and staff will review the document in detail. The proposed schedule and process for adoption of the IPMC is as follows: May 4, 2006 Public Meeting at Denia Recreation Center May 15, 2006 Public Meeting at North Lakes Recreation Center May 18, 2006 Construction Advisory and Appeals Board May 24, 2006 Planning & Zoning Work Session June 6, 2006 Planning & Zoning Public Hearing June 20, 2006 Planning & Zoning Recommendation to Council July 18, 2006 City Council Work Session August 1, 2006 City Council Regular Session Resource Information To provide Code Enforcement service at the same level of other Metroplex cities, a survey was completed of 11 other municipalities. This survey compared the number of Code officers to population and square miles served. Metroplex average 1 officer per 4.62 square miles Denton average 1 officer per 12.41 square miles 10 additional Code Officers needed to meet Metroplex average for square miles served Metroplex average 1 officer per 12,100 population served Denton average 1 officer per 16,924 population served 2 additional officers needed to meet Metroplex average for population served A supplemental package for two additional Code Enforcement Officers including equipment and training needs was submitted for consideration in the FY 2006-07 budget proposal. FY 2006-07 total = $172,726 II. Property Assessment Survey To establish a baseline of information regarding existing property conditions, it is recommended that a property assessment survey be completed. Staff has identified two cities that have recently completed similar surveys to determine the scope, time frame and cost of this type of study. Exhibit 2 is a table summarizing the information gathered. In general, cities determine the assessment criteria for the surveys. On average, cities select up to 10 items to be evaluated. The surveys can include assessments of the exterior of structures, including accessory buildings and fences, city infrastructure on or near the property (sidewalks, curb and gutter), and nuisance violations such as tall grass and weeds, yard parking, and trash and debris of single-family, multi-family and commercial properties. Denton has approximately 22,000 single-family properties and 400 multi-family complexes. The assessments are conducted as windshield surveys and are performed by two people: one driver and one surveyor. Properties are assessed and scored based on what is visible from the roadway. Cities supply these firms with GIS maps of developed parcels with platted lots. The assessment findings are returned to the cities in GIS format. Typically, properties are scored on a scale of 1 to 4 based on condition. 1 Meets Code 2 Minor Code Violation(s) 3 Major Code Violation(s) 4 Dilapidated Condition In addition to providing an accurate baseline of information on existing property conditions throughout the city, this information will allow staff to establish performance measures to more accurately track code compliance citywide and productivity. Survey Development Schedule & Process May 1, 2006 Advertise RFP for contract professional services June 5, 2006 Interview qualified proposals & select survey consultant June 20, 2006 Contract considered by City Council Nov. 30, 2006 Survey Completed Recommendation Identify funding and develop RFP for contract professional services for a Property Assessment Survey. Resource Information Based on information provided from other cities, it is estimated that a consultant would charge approximately $3.50 per parcel (structure) for a survey. With 22,000 single-family structures and 400 multi-family complexes (approx. 800 buildings) in Denton, a rough estimate for this survey would be $80,000 - $100,000. III. Rental Inspection Program The purpose of establishing a rental inspection program is to aid in maintaining and/or increasing property values and neighborhood desirability by requiring minimum standards of cleanliness, property maintenance, and structural integrity of rental units and their premises. Rental inspection programs work to ensure that rental structures and their premises are safe and clean for habitation. Inspection programs aid in reversing neighborhood decline, and reclaim and restore older established communities while ensuring that property values and quality of life are maintained in newly developed areas. Inspections would include minimum structural standards related to plumbing and sewage disposal, electrical wiring, foundation and roof condition, existence of window screen, as well as standards related to unsanitary conditions such as the presence of rodents, insects, trash, junked vehicles, and tall grass and weeds. In Denton, Code Enforcement officers would focus on identifying and inspecting the interiors and exteriors of single-family and multi-family rental properties. Officers would work with owners and management companies to bring properties into compliance with City codes. Substandard properties that are not brought up to code would be placed on a substandard property list for future disposition. Multi-Family Licensing and Inspection Program This program would consist of the annual licensing and inspection of unoccupied multi-family (MF) properties. It is expected that all exteriors and up to 10% of interiors would be inspected annually. A letter of advance notice would be sent to the complex to schedule the annual inspection. Occupied units are only inspected upon tenant request. The annual licensing fee would be $12.60 per unit. There is no charge for the initial inspection or the first re-inspection. A fee of $20 for each unremediated violation, not to exceed $40 per unit, would be charged for each re-inspection after the first re-inspection. Estimated annual revenue generated from these fees totals $231,895. Implementation of this program to inspect the 400 complexes in Denton would require the addition of four Code Enforcement officers and associated vehicles, equipment and office costs. Single-Family Certificate of Occupancy Renewal Program This program is a Certificate of Occupancy (CO) renewal and does not have a registration component. Internal and external inspections would occur with a change of tenancy. The CO would be issued to the owner. Fees for this program would be $12.60 per year for single-family rentals, and $25.20 per year for duplex rentals. Estimated annual revenue generated from these fees total $69,300. Implementation of this program would require the addition of two Code Enforcement officers and associated vehicle, equipment and office costs. Program Development Schedule & Process August 1, 2006 Adopt inspection provisions in the IPMC September 2006 Develop inspection program procedures October 2006 Begin hiring of Code Enforcement officers if positions approved Recommendation Submit supplemental packages for inspection programs for consideration in FY 2006-07 budget process. Resource Information The net expense for a Multi-Family program would total $52,058 in FY 2006-07, and the net expense for a Single-Family program would total $91,164 in FY 2006-07. These totals include some one-time expenses for vehicles and equipment. IV. Substandard Housing At the completion of the property assessment survey, staff will evaluate the information and develop a strategy to begin bringing violations into compliance and developing a prioritized list of substandard structures to process for demolition. Prioritization would be based on conditions that most endanger the life, limb, health, property, safety or welfare of the public or the occupants of the structure. Code Enforcement officers would begin working individual property cases as prioritized. Structures identified for demolition would follow the existing process as detailed in Chapter 28 of the Code of Ordinances. This process is determined by the Texas Local Government Code and meets the minimum requirements of that Code. Attached for your information is a table detailing the cost and time involved in moving one structure through the demolition process. Due to the political sensitivity of the demolition issue and the resources required to administer the process, the City of Denton has not been aggressive in pursuing the demolition of structures. Demolition funding through CDBG Program Demolition of substandard buildings is an eligible activity under the Community Development Block Grant (CDBG) program. The City of Denton has used CDBG funds for this purpose since 1984. In the past five years, 27single-family structures have been demolished under the program. The average cost for the demolition of a single-family structure during this period was approximately $3,200, however, staff has indicated that the current cost would be closer to $5,000 per unit. The City of Denton currently has CDBG funding of $74,970 set aside for the Demolition Program. The City?s program targets vacant, substandard structures that have either been condemned by the Construction Advisory and Appeals Board or requested to be demolished by a low-income property owner. CDBG funds have not been used to demolish structures that were recently occupied due to relocation requirements enforced by the U.S. Department of Housing and Urban Development. These requirements entail payment of relocation costs and rental assistance to the relocated household. If the relocated family is low-income, rental assistance must be provided for a five-year period. Implementation Schedule & Process The existing substandard housing program is administered in the Building Inspection office as an ancillary service. Implementation of this program beyond the current complaint-driven system will require additional resources. August 1, 2006 Adopt substandard housing provisions in the IPMC October 2006 Begin hiring of Building Inspectors if positions approved. Recommendation Submit a supplemental package for consideration in the FY 2006-07 budget process. Resource Information A supplemental package for 2 additional staff including equipment, training needs and demolition dollars was submitted for consideration in the FY 2006-07 budget proposal. FY 2006-07 total = $235,464 OPTIONS Direct staff to proceed with the proposed recommendations as deemed appropriate. Direct staff to make changes and/or eliminate recommendations as deemed appropriate. PRIOR ACTION/REVIEW (Council, Boards, Commissions) February 14, 2006 City Council Work Session ?

BACKGROUND On April 19, 2005, the City of Denton updated its Water Conservation and Drought Contingency Plan (the ?Plan?) as required by the Texas Commission on Environmental Quality. The Plan was updated to comply with a series of bills passed to fulfill a statewide water conservation initiative th mandated in 2003 by the 78 Texas Legislature. A comprehensive description of this initiative and Denton?s 2005 update is provided in Exhibit 2 and Exhibit 3. Perhaps the most notable of the 2003 water conservation bills is HB 2660, which requires five and ten-year water savings goals in water conservation plans. For municipal water providers, the State Water Conservation Task Force suggests a minimum annual reduction of one percent in total per-capita, based on a five- year rolling average, until a per-capita of 140 or less is achieved. Denton?s five and ten-year goals were a reduction of 9 gallons per day per-capita to 180 per-capita by 2009 and 18 gallons per day per-capita to 171 per-capita by 2014. In order to comply with these requirements and meet the established goals, Denton?s Plan calls for the continued implementation of Denton?s ongoing conservation effort (Exhibit 3) along with both the moderate growth of Denton?s effluent reuse program and the implementation of a lawn and landscape irrigation ordinance. A lawn and landscape ordinance is intended to minimize waste in landscape irrigation. In North Central Texas, Dallas, Arlington, Carrollton, Frisco, and Allen all have similar forms of a lawn and landscape irrigation ordinance; Fort Worth is in the process of implementing an ordinance this spring. Dallas? effort to help minimize water waste through an irrigation ordinance began in 2001 and since then has issued 1,491 warnings and 12 citations. Dallas enforces their ordinance through their Code Enforcement Division. Arlington implemented their ordinance in 2004 and enforces their ordinance through both their Water Utility staff and Neighborhood Services Division (Code Enforcement) and, to date, have not had to issue any fines. Frisco and Carrollton implemented their ordinances last year. Both cities enforce their programs entirely through their Water Utility departments and neither has had to issue fines (Carrollton) or terminate service (Frisco). Based on personnel interviews with staff members of the aforementioned cities, the common thread is that generally the enforcement of the ordinance is mostly an educational exercise; outside of a very few difficult customers, implementation and enforcement has not been overly problematic. 1 Proposed Ordinance According to Denton?s Plan, the ordinance was to be implemented in 2007, with an educational program preceding it in 2006. However, due to the public?s awareness of local water supplies and water conservation issues brought about by the current drought, along with the potential for the drought to persist throughout the summer, staff suggested implementing the ordinance in 2006 (Exhibit 4). Feedback from Council members indicated that it would be prudent to implement the ordinance this year, while potentially in a drought and at a time when there is a high awareness of water conservation. The ordinance being proposed is based on practical, common sense conservation measures that are consistent with other cities in the region and includes the following elements (see draft ordinance, Exhibit 1): Prohibition of outdoor watering with sprinklers from 10:00 a.m. to 6:00 p.m. every day from June 1 through September 30. (Watering with hand-held hoses, soaker hoses, or containers is allowed.) Requirement that all new irrigation systems include rain and freeze sensors. Requirement that all new irrigation systems be in compliance with state design and installation regulations (Texas Administrative Code Title 30, Part 1, Chapter 344). Prohibition of design, operation, or maintenance of irrigation systems that excessively water impervious areas, or generate excessive runoff from over watering, such that a constant stream of water overflows onto a street or drainage area. Prohibition of use of poorly maintained sprinkler systems that waste water (broken or improperly working heads). Prohibition of outdoor watering during any form of precipitation. Enforcement of the ordinance by a system of warnings followed by fines for continued or repeat violators. In addition to the requirements related to irrigation, staff is also proposing a water waste component in the ordinance. The State Water Conservation Implementation Task Force was created to fulfill the mandate of the legislation resulting from the 2003 water conservation bills. The Task Force was assigned several tasks, one of which included identifying, evaluating, and selecting Best Management Practices (BMPs) for municipal water uses. Prohibition of wasting water was among the Task Force?s suggested BMPs. Staff is proposing to include the following component in the ordinance: Prohibition of leaking outside faucets, leaks on customer service lines, and excessive leakage of interior plumbing Staff also anticipates there may be special cases where there is an extreme hardship in meeting ordinance requirements. Staff will evaluate those needs on a case-by-case basis and, if necessary, provide relief according to the requirements outlined in the Variance section of the ordinance. Implementation Staff is proposing to implement enforcement of the ordinance through both Utility personnel and the city?s existing Code Enforcement Program. As with the other cities in the region implementing irrigation ordinances, enforcement will most likely be initiated by citizen complaints and Utility personnel that observe violations while working out in the field. Staff proposes to enforce the program in the following manner: st 1 Offense Door hanger delivered by Utility staff member nd 2 Offense Warning issued by a Code Enforcement Officer rd 3 Offense Citation issued by Code Enforcement Officer with a fine of $250 th 4 Offense Termination of water service by Water Utility Department The offenses would accumulate on a per year basis, such that at the beginning of each year every customer would begin with zero offences. Staff is also recommending that for the first year of implementation, only warnings will be given. Prior to implementation of the ordinance, staff will notify all local irrigators and irrigation customers with high demands to inform them of the requirements being proposed in the ordinance, and if necessary, meet with them individually to discuss concerns regarding compliance with the ordinance. In addition, Water Utility staff will meet with Denton?s Facilities and Parks and Recreation personnel to discuss issues related to citywide irrigation procedures and ensure that the city?s facilities will be in compliance with the ordinance.

AGENDA INFORMATION SHEET : AGENDA DATEApril 19, 2005 : Utility Administration DEPARTMENT Howard Martin, Utilities 349-8232 ACM: SUBJECT AN ORDINANCE AMENDING CHAPTER 26 OF THE CODE OF ORDINANCES OF THE CITY OF DENTON, TEXAS BY ADDING THERETO §26-233 ?WATER CONSERVATION AND DROUGHT CONTINGENCY PLAN?; AND §26-234 ?CRIMINAL AND CIVIL PENALTIES?; ADOPTING A WATER CONSERVATION AND DROUGHT CONTINGENCY PLAN IN ACCORDANCE WITH THE REQUIREMENTS OF THE LAW; ESTABLISHING CRITERIA FOR THE INITIATION AND TERMINATION OF DROUGHT RESPONSE STAGES; ESTABLISHING RESTRICTIONS ON CERTAIN WATER USES; ESTABLISHING PROCEDURES FOR GRANTING VARIANCES; PROVIDING A CRIMINAL PENALTY NOT TO EXCEED $2,000 PER VIOLATION; PROVIDING A CIVIL PENALTY NOT TO EXCEED $1,000 PER DAY PER VIOLATION; AND CHARGING VARIOUS 20% SURCHARGE PENALTIES ON EXCESSIVE WATER USE; PROVIDING A SAVINGS CLAUSE; PROVIDING A SEVERABILITY CLAUSE; AND PROVIDING AN EFFECTIVE DATE. BACKGROUND On March 28, 2005, staff presented the Public Utilities Board (PUB) (Exhibit 2) with the strategy for updating Denton?s Water Conservation and Drought Contingency Plan. The update th is required by the Texas Commission on Environmental Quality. The March 28 agenda item contained detailed information pertaining to the legislative history of, and recent legislative th changes to, the water conservation and drought contingency plan. The 78 Texas Legislature passed seven water conservation bills in 2003. In short, two of the bills directly affected water conservation plans, Senate Bill 1094 and House Bill 2660. SB 1094 created a task force on water conservation to review, evaluate, and recommend levels of water use efficiency and conservation for Texas. Requirements for quantified five-year and ten-year water savings goals in water conservation plans were established by HB 2660. However, these goals are not enforceable. A third bill passed in 2003, HB 2663, established the requirement for drought contingency plans to include specific quantified goals for water use reductions during periods of water shortages and drought. th The March 28 agenda item also contained information related to local and regional per-capita water demand as well as the proposed strategy for complying with legislative requirements and meeting water conservation goals. Denton?s water demand per-capita compares favorably with the regional average, the City of Dallas?, and those of Dallas? larger customer cities. A number of factors contribute to an area?s per-capita including variations in climate, municipal demographics, water utility profiles, and local water conservation efforts. The City of Denton implemented a water conservation plan in December of 1999. Denton?s current plan includes a water conservation rate structure, a public education program, an informative web site, a xeriscape program, residential water audits, and an effluent reuse program. To further reduce EXHIBIT 2 potential water loss, the Water Department manages a waterline replacement program and conducts annual water audits. The current plan also established a water conservation goal of a fifteen percent reduction in per-capita water consumption by the year 2050. Water Conservation Plan Executive Summary The State Water Conservation Implementation Task Force (Task Force), with members appointed by the Texas Water Development Board (TWDB), was created to fulfill the mandate of the legislation incorporated in Section 6 of Senate Bill 1094. One of the mandates of SB 1094 was the establishment of state wide per-capita targets and goals to be considered by water providers. For municipal water providers, the Task Force suggested a minimum annual reduction of one percent in total per-capita, based upon a five-year rolling average, until such time as the entity achieves a total per-capita of 140 or less. Based on historical per-capita data, best management practices (BMPs) water savings analysis, and recommendations by the Region C Water Supply Planning Group?s water conservation consultant, staff believes that a one percent per year reduction in per-capita water use is obtainable over the next five and ten-year periods. Denton?s specific goals are as follows: Achieve 2009per-capita water use of 180 gpcd or less (five-year target). This represents a reduction of 9 gpcd from the TWDB?s projected per-capita water use. Achieve 2014per-capita water use of 171 gpcd or less (ten-year target). This represents a reduction of 18 gpcd from the TWDB?s projected per-capita water use. According to water savings analysis conducted by the Region C Water Supply Planning Group and Denton Water Utilities staff, the water conservation goals of this plan can be accomplished through continued implementation of Denton?s current conservation effort, water savings resulting from low-flow plumbing fixtures and the new federal clothes washer standards, the implementation of a lawn and landscape irrigation program, and the moderate growth of Denton?s effluent reuse program. The lawn and landscape irrigation program, a new update to the current plan, will be developed and implemented in phases over the next few years. The program will include an ordinance that may contain the following components: restrict watering to certain times of the day, deter excessive watering of impervious surfaces, not allow watering during any form of precipitation, require rain sensors on all new systems, and require proper maintenance of irrigation systems. The implementation of the program in phases will allow time for staff to develop an ordinance ensuring sufficient pubic participation as well as provide an adequate amount of time necessary to educate customers about the requirements and restrictions of the ordinance. Drought Contingency Plan Executive Summary Revisions in Denton?s drought contingency plan are reflective of the 2005 changes to Dallas? drought contingency plan. The need to coordinate Denton?s plan with the Dallas? plan is appropriate due to the following reasons: 1) Denton?s water supply reservoirs (Lake Ray Roberts and Lake Lewisville) are shared with Dallas and Denton is the minority water rights holder in both reservoirs; 2) Denton is an untreated water supply customer of Dallas and will be affected by restrictions that may be initiated by Dallas? plan, and 3) consistency between plans will provide for a more effective implementation of Denton?s drought contingency plan as a result of Dallas? regional media coverage. Revisions in Denton?s 2005 update to the drought contingency plan include: Minor changes to trigger conditions for the Type B water management condition; Minor additions and edits to the menu of possible actions of water use restrictions for demand reduction; and, Adjustments to the specific quantified targets for water use reductions during periods of water shortages and drought. Revisions to the drought contingency plan were not previously presented to the PUB or the Council Environment Committee as staff received Dallas? draft 2005 update subsequent to those meetings. Denton?s Water Conservation and Drought Contingency Plan has been updated to reflect the changes describe above. The style of the plan has also been reformatted to closely resemble the model plan developed by the Region C Water Supply Planning Group. The Denton Water Conservation and Drought Contingency Plan is included in Exhibit 3. OPTIONS 1. Accept the proposed Plan without modification. 2. Accept the proposed Plan with modifications. 3. Do not accept the proposed Plan. RECOMMENDATION Staff recommends Option 1, accepting the proposed ordinance without modification. PRIOR ACTION/REVIEW (Council, Boards, Commissions) The Strategy for the 2005 update to the Water Conservation and Drought Contingency Plan was presented to the Public Utilities Board on March 28,2005 The Strategy for the 2005 update to the Water Conservation and Drought Contingency Plan was presented to the Council Environment Committee on March 29,2005 The 2005 Water Conservation and Drought Contingency Plan was presented to the Public Utilities Board on April 11, 2005. The PUB approved the Plan with a 5-0 vote recommending a change in the Plan to include a day of week watering schedule instead of the existing 5-day watering schedule.

Ordinance - Water Conservation and Drought Contingency Plan 2. PUB Agenda Item ? March 28, 2005 3. 2005 Water Conservation and Drought Contingency Plan PUBLIC UTILITIES BOARD AGENDA INFORMATION SHEET : AGENDA DATEJanuary 24, 2005 : Utility Administration DEPARTMENT Howard Martin, Utilities 349-8232 ACM: SUBJECT Receive a report from staff, hold a discussion and provide direction concerning Denton's 2005 update to the Water Conservation and Drought Contingency Plan BACKGROUND Legislative History The City of Denton adopted its Water Conservation and Drought Contingency Plan on December th 7 1999. The plan was developed according to criteria established by the then Texas Natural Resources Conservation Commission (now Texas Commission on Environmental Quality (TCEQ)) and established a water conservation goal of a fifteen percent reduction in per-capita water consumption by the year 2050. Per-capita, defined by the Texas Water Development Board (TWDB), is the total amount of water diverted and/or pumped for potable water use divided by the total population. Per-capita is also commonly referred to as gallons per capita per th day or gpcd. Since adoption of Denton?s plan, the 78 Texas Legislature passed seven water conservation bills. The most notable of the conservation bills, all of which were passed in 2003, are Senate Bill 1094 and House Bill 2660. SB 1094 created a task force on water conservation to review, evaluate, and recommend levels of water use efficiency and conservation for Texas. Requirements for quantified 5-year and 10-year water savings targets in water conservation plans were established by HB 2660. The State Water Conservation Implementation Task Force (Task Force), with members appointed by the TWDB, was created to fulfill the mandate of the legislation incorporated in Section 6 of Senate Bill 1094. The Task Force was assigned several tasks including identifying, evaluating, and selecting Best Management Practices (BMPs) for municipal, industrial, and agricultural water uses and evaluating the cost and benefits of the selected BMPs. As a result, the Task Force developed TWDB Report 362, Water Conservation Best Management Practices Guide.This guide, released in November 2004, includes 21 BMPs for municipal water users and serves as a resource for entities volunteering to implement BMPs appropriate for their situation. th In addition to Report 362, the Task Force also produced a Special Report to the 79 Legislature. This report, also issued in November 2004, recommended a standardized methodology for calculating, reporting, and monitoring per-capita water use data. The Special Report also established state wide per-capita targets and goals to be considered by water providers. HB 2660 required the commission and board to establish these goals. For municipal water providers, the report suggested a minimum annual reduction of one percent in total per-capita, based upon a five-year rolling average, until such time as the entity achieves a total per-capita of 140 or less. EXHIBIT 3 March 27, 2006 PUB Item 4, Exhibit 3 Page 2 of 6 It is important to note that these goals are only guidelines and are not enforceable. HB 2660 also required the commission and board to develop model conservation plans for water supplies; and, beginning May 1, 2005, all water conservation plans must include specific, quantified 5-year and 10-year targets for water savings. Legislative changes to Water Conservation and Drought Contingency Plans Effective October 7, 2004, Title 30 Chapter 288 of the Texas Administrative Code (TAC) entitled Water Conservation Plans, Drought Contingency Plans, Guidelines and Requirements requires the holder of an appropriation of surface water in the amount of 1,000 acre-feet a year or more for industrial, municipal and other non-irrigation uses develop, submit and implement a water conservation plan meeting the requirements of Subchapter A of Chapter 288. The water conservation plans must be submitted to the executive director of the Texas Commission on Environmental Quality no later than May 1, 2005. In addition, retail public water suppliers providing water service to 3,300 or more connections must also submit a drought contingency plan to the executive director by the same date. Changes to Title 30 Chapter 288 Subchapter A Rule 288.2 (Water Conservation Plans) and Rule 288.5 (Drought Contingency Plans) of the Texas Administrative Code (TAC), effective November 7, 2004, include the following: WATER CONSERVATION PLANS Goals: ? Until May 1, 2005, water suppliers were required to specify conservation goals for municipal o per-capita water use, the basis for development of such goals, and a time frame for achieving the specified goals. Beginning May 1, 2005, specific quantified five-year and ten-year targets for per-capita o water savings for municipal use are also required. The goals established by a public water supplier are not enforceable under the code. ?Update of Plan: Beginning May 1, 2005, public water suppliers must review and update its water conservation plan, as appropriate, based on an assessment of previous 5-year and 10-year targets and any other new or updated information. Update of the plan every five years requires reporting water sales by specific user class (i.e., residential, commercial, institutional, industrial). Staff is currently working on a process to code the specific customer user classes into the Harris billing system. DROUGHT CONTINGENCY PLANS ?Quantified Targets for Water Use Reductions:The Drought Contingency Plan must include, specific quantified targets for water use reductions to be achieved during periods of water shortage and drought. Region C, City of Dallas (including customer cities), and City of Denton per-capita Population and water demand numbers are available at the TWDB website. Based on TWDB water demand and population numbers for the year 2000, the average per-capita for Region C was 246. The City of Dallas? per-capita for the same year was higher at 262. Per-capita for March 27, 2006 PUB Item 4, Exhibit 3 Page 3 of 6 Denton in 2000 was 189, less than both Dallas and the Region C average. Exhibit 1 shows the year 2000 per-capita for the City of Dallas, the City of Denton, and all other Dallas customer cities with a population greater than 25,000. Compared to Dallas and their larger customer cities, Denton?s per-capita water demand (189) is less than the mean (199) and just slightly under the median (190). It is important to note that the year 2000 is being used to establish baseline per- capita for the following reasons: 1) the population figures are more accurate than any single-year population estimate between 1990 and 2000; 2) according to the Palmer Drought Severity Index the year 2000 was the driest year in the last decade for the majority of regions in the State; and, 3) the year 2000 water use data also takes into account the water use savings that have resulted from the 1991 State Water-Efficient Plumbing Act and conservation programs implemented by the water utility. Update to Denton?s Plan The current plan meets all TCEQ requirements for Water Conservation and Drought Contingency Plans except for the recently added specific 5-year and 10-year conservation goals and the submittal of those goals in the updated plan to the TCEQ by May 1, 2005. Denton?s current Drought Contingency Plan already contains quantified targets for water use reductions during times of shortage or drought. Staff will review those targets prior to preparing the final draft of the updated plan. Due to having one of the highest per-capita demands in Region C, and in the state, the City of Dallas is currently pursuing an aggressive water conservation effort. Denton?s per-capita, on the other hand, is substantially less than Dallas? and compares favorably to Region C as a whole. In determining the need for conservation, it is also important to consider supply and demand; Denton?s short-term treatment and supply capacities exceed demand. Due to these factors, staff suggests pursuing a less aggressive conservation effort than Dallas. Staff also believes it is in the best interest of DWU to take a more moderate approach to water conservation at this point in time due to uncertainties pertaining to potential regulatory consequences of specific water savings goals in the future. Nonetheless, Denton will benefit from Dallas? effort through their regional media campaign. In staff?s opinion, Denton already has a respectable water conservation plan, which consists of the following components: Conservation Water Rate Structure for Residential Rate Class- comprised of an inverted- block rate such that the price of water increases with increasing consumption Public Awareness and Education Program - includes bill inserts, brochures, a school education program, public speaking engagements, and public service announcements. Web Site - DWU maintains a web site with water conservation tips and answers to frequently asked water conservation questions. Xerioscape Program - offers a free semi-annual landscape management class and distributes Texas Smartscape CDs at local events and upon request Waterline Replacement Program ? replaces waterline on a worst-first basis which is effective in reducing the number waterline breaks March 27, 2006 PUB Item 4, Exhibit 3 Page 4 of 6 Annual Internal Water Audit ? water accounting system useful for estimating and controlling unaccounted-for water Residential Water Audits ? trained staff conduct on-site water audits for residential customers identifying potential water waste and demonstrating water conservation techniques. Effluent Reuse Program ? reclaimed wastewater is sold to customers for non-potable uses, primarily irrigation. Staff feels the TWDB Task Force?s suggested annual reduction of one percent per year in total per-capita may be reasonable for Denton. Based on available data, staff believes the goal can be achieved through continued implementation of the components in the current plan, implementation of a lawn and landscape irrigation program, and moderate growth of Denton?s reclaimed effluent reuse program. The lawn and landscape irrigation program would be developed and implemented in phases over the next few years. The program would include an ordinance that would restrict watering to certain times of the day and would deter excessive watering of impervious surfaces. The ordinance would not allow watering during any form of precipitation and would require rain sensors on all new systems. Proper maintenance of irrigation systems necessary to reduce waste of water would also be required. The implementation of the program in phases would allow time for staff to develop an ordinance ensuring sufficient pubic participation as well as provide an adequate amount of time necessary to educate customers about the requirements and restrictions of the ordinance. The Consultant for the Region C Planning Group responsible for Region C Water Conservation believes that Denton will likely do its share in meeting the long-term Regional conservation goals based on automatic water savings and the implementation of moderate conservation measures. Automatic water savings result from the 1991 state requirements for low-flow plumbing fixtures, the impact of increasing water rates over time, and a new federal clothes washer standard that will go into effect in 2007. Moderate conservation measures include public and school education programs and a Water Waste Prohibition ordinance (different terminology for lawn and landscape irrigation ordinance). The Consultant estimates that these components will reduce demand by 6.7 percent in 2010. At this time, the total projected savings in the Consultant?s estimates do not include the savings that will result from Denton?s reuse program. The Consultant is currently working with staff to estimate savings from reuse. Twenty-one Municipal BMPs were published in the Task Force?s Water Conservation Best Management Practices Guide. Exhibit 2 shows which BMPs are already being implemented, which BMPs will be implemented in the first five years of Denton?s updated Water Conservation Plan, and whether or not the BMP is being recommended for Denton by the Region C Consultant. In order to meet the five and ten-year conservation goals Denton will continue to implement the current the plan, phase in a Lawn and Landscape Irrigation Ordinance, and March 27, 2006 continue to expand the reuse program. In addition to the proposed conservation plan, a large portion of per-capita water savings will result from low-flow fixtures, increasing rates, and the federal clothes washer standards. Denton?s specific goal of a one percent reduction of per-capita per year in the first five years, based on estimated savings from current conservation measures, a lawn and landscape irrigation ordinance, and moderate growth in Denton?s reuse program over the time period, would result in a 9-gallon per day reduction in per-capita by the year 2009. Current conservation measures PUB Item 4, Exhibit 3 Page 5 of 6 include savings from state required low-flow plumbing fixtures, the implementation of the federal clothes washer standards, increasing water prices over time, and the water conservation components of Denton?s current plan. By the year 2014, the second required evaluation and update period of the plan, meeting the one percent reduction in per-capita per year would result in a per-capita reduction of approximately 18 gallons per day. OPTIONS 1) Establish specific 5-year and 10-year water savings goals at reducing per-capita by one percent per year 2) Establish specific 5-year and 10-year water savings goals that are more aggressive than reducing per-capita by one percent per year 3) Establish specific 5-year and 10-year water savings goals that are less aggressive than reducing per-capita by one percent per year RECOMMENDATION Staff recommends Option 1; establish specific 5-year and 10-year water savings goals at reducing per-capita demand by one percent per year. The established goal could be achieved through automatic water savings, continued implementation of Denton?s Water Conservation Plan, a phased in implementation of a Lawn and Landscape Irrigation Ordinance, and the moderate growth of Denton?s reclaimed effluent reuse program.

EXHIBITS 1. Per-capita Water Demands 2. Water Conservation Best Management Practices Prepared by: Submitted by: Tim Fisher, P.E. David Wachal Assistant Director, Water Utilities Water Utilities Coordinator WATER UTILITIES 901-A Texas Street Denton, TX 76209 (940) 349-8463 Fax (940) 349-7334 MEMORANDUM TO: Howard Martin, Interim City Manager FROM: Tim Fisher, Assistant Director Water Utilities THRU: Jim Coulter, Director of Water Utilities DATE: January 13, 2006 SUBJECT: Water Conservation & Drought Contingency Plan Update on Water Supply Condition Denton Water Utilities staff continues to monitor water levels in Lake Lewisville and Lake Ray Roberts and water system demands in accordance with the Denton Water Conservation & Drought Contingency Plan. The Drought Contingency Plan identifies three different types of water shortage situations which might occur and that would result in different types of demand side management strategies. These water shortage conditions are listed below: Type A ? Water supplies are low. Type B ? Water demand approaches system capacity. Type C ? Short-term deficiencies limit supply capability. The plan also identifies four stages of management strategies designed to address the severity of the water supply shortage situation. These include: Stage 1 ? Mild Stage 2 ? Moderate Stage 3 ? Severe Stage 4 ? Emergency. EXHIBIT 4 Memo to Mayor and Members of the City Council January 13, 2006 Page 2 of 4 The Plan was originally adopted by the City Council on January 4, 2000, and was revised in accordance with TCEQ requirements by staff and adopted by the City Council on April 19, 2005. Since this plan has been adopted, the Cities of Denton and Dallas initiated Type A, Stage 1 or 2 management strategies during much of the summer of 2000. Due to high summertime water demands coupled with a mechanical failure of one of the city?s lake station pumps, Denton activated Type B, Stage 1 and Type C, Stage 2 management strategies during the late summer of 2001. The current lake level conditions for Lake Lewisville and Lake Ray Roberts have declined since the spring of last year and the severe drought weather conditions in the DFW area over the past twelve months has resulted in a steady decline in conservation pool levels over the past nine months. As a consequence, staff anticipates activation of a Type A trigger condition is a real possibility within the next three to four months. Depending upon how the weather patterns occur over the next five months, it is possible that we could see Type A trigger conditions to progress from Stage 1 to Stage 2 or even Stage 3 conditions by mid to late summer. I have enclosed a summery of Type A plan triggers along with some information showing recent trends in the water supply volumes (expressed as % of conservation pool) for the Dallas five-lake system (Lakes Ray Roberts, Lewisville, Grapevine, Hubbard and Tawakoni) as well as the Denton/Dallas two lake supply system (Lake Lewisville and Lake Ray Roberts). While Lake Lewisville has dropped below 64% of conservation pool levels, Lake Ray Roberts has nearly 88% of its conservation pool water supply. The Denton/Dallas water supply system is in better condition than many of the other regional water suppliers. Some of these suppliers have had to implement water restrictions due to reaching their drought plan trigger conditions earlier in this drought period than the cities of Denton and the Dallas Water Utilities system and their wholesale customers. Denton activates their drought plan at the same time Dallas Water Utilities does under Type A trigger conditions due to the multi lake system operated by Dallas and the shared lake system with Denton. I have also enclosed information on monthly rainfall amounts for last calendar year recorded at the City?s rain gauge station at the Lake Lewisville Water Treatment Plant compared to the average monthly rainfall over the past 17 years from our Utilities Forecast. The total rainfall for calendar year 2005 was 16.". The average rainfall for the prior 17 years was 37.86" per year. 13 The lowest rainfall during that time frame was 24.19" in 1996. The second lowest amount was 27.67" in 1999. That forecast also averages the summer rainfall (June - August) for those 17 years. The summer average is 8.7" versus 1.57" for 2005. On the forecast graph a dry year is noted as 27", a normal year is 37" and a wet year is 47". Needless to say, 2005 was a very dry year and we were very fortunate to have a very wet year in 2004 that help keep lake levels near conservation pool levels through much of the spring of 2005. Please be advised that Stage 1 drought plan activation result in mandatory water will not restrictions for any retail or wholesale water customer but will begin the launching of the City?s drought plan public education program. Stage 2 drought plan activation introduces mandatory water restrictions for the City of Denton governmental customers, including all City irrigated Memo to Mayor and Members of the City Council January 13, 2006 Page 3 of 4 landscaping and parks. Stage 3 drought plan activation introduces mandatory water restrictions for all retail and wholesale water customers. The water utilities staff has been working with the public information staff to prepare for implementation of the drought plan since it was revised last year. The city?s web page has the updated version of the city?s adopted Water Conservation and Drought Management Plan available for the public to download and view in PDF format. There are also links for water saving tips, information on the city?s water audit program and water conservation program as well as information on the new twice a week watering schedule that replaced the more complicated five day watering schedule that was a part of the 2000 version of the drought plan. All of these can be accessed through the Water Utilities section of the city?s website or through the site search window. Recent long-range weather forecasts suggest the next six months will continue to be drier than normal for the North Texas region. Based upon these conditions, it may be advisable for the City to consider promoting an accelerated water conservation public education program in advance of formal activation of the drought management plan. In addition, the 2005 updated version of the water conservation plan anticipated implementation of a Water Waste Ordinance by the third year of the five year plan (the summer of 2007). It may be prudent to consider implementing this ordinance for implementation by this up coming summer. The Water Waste Ordinance would include provisions similar to those adopted by the Cities of Dallas in 2001 and Arlington in 2005. Key provisions of a Water Waste Ordinance include restrictions on: Water irrigation during the heat of the day during summer months. Excessive watering resulting in running water entering streets and storm drains. Watering of driveways, pavements or sidewalks. The Water Waste Ordinance would also require installation of rain/freeze sensors for all new sprinkler systems. Public acceptance of this type of water conservation ordinance will likely be better during a drought condition than when lakes are full and when rainfall is plentiful. If the City Council agrees with this suggestion, staff can begin working on a draft ordinance for the Public Utilities Board review and for a City Council work session within the next few months. With respect to other plan trigger conditions, forecasted water demands over the peak summer demand period this summer should not result in activation of the plan due to Type B trigger conditions. With the completion of the new Lake Ray Roberts Water Treatment Plant in 2003, Type B triggers should not be of concern for the City of Denton for the next five to eight years. Please be advised that as water system demands increase over the summer months, there is always an increased risk of having a Type C emergency event. A Type C trigger condition occurs when an unplanned emergency event reduces existing water system capacity to a level approaching current water system demand. Examples of these include a major water main break, an extended power failure to a major treatment plant or pump station facility, or the mechanical failure of a large pump. While Type A and Type B trigger conditions impact all of the water Memo to Mayor and Members of the City Council January 13, 2006 Page 4 of 4 customers, Type C trigger conditions may only impact portions of the distribution system in some cases (for instance a pump station failure for a specific pressure zone). Staff will keep you apprised of the water supply system and brief you if activation of the drought plan due to Type A trigger conditions becomes necessary. If activation of the drought management plan is advisable, staff will notify you and discuss the recommended course of action.

Key issues of the ordinance would be a summertime ban on 23water irrigation during the heat of the day, or during times of precipitation; excessive watering 24resulting in running water entering streets and storm drains, watering of driveways, pavements or 25sidewalks; and, proper maintenance of sprinkler systems. 26 27There was a general discussion regarding proposed enforcement strategies. Board Member 28Smith stated that the conservation goals and requirements identified in the Denton Development 29Code were in conflict with the proposal regarding the Lawn and Landscape Irrigation and Water 30Waste Ordinance and thought that a concurrent review of both by Council might be helpful. 31 32General direction for staff was to proceed with the implementation schedule. 33 Exhibit 5 AGENDA INFORMATION SHEET April 11, 2006 AGENDA DATE: Utilities Administration DEPARTMENT: Howard Martin, 8232 CM: ______________________________________________________________________________ SUBJECT Receive a report and hold a discussion regarding the Water, Wastewater, and Solid Waste Forecasts. BACKGROUND The City of Denton?s Utility Departments have prepared new forecast that will support development of the FY 2007-2011 CIP?s, FY 2007 operating budgets, and other long-range service requirements. The first phase of the forecast process involves gathering and analyzing historical information to determine relationships between population, customers, production, consumption or usage data. The next phase is to apply the historical trend data to future growth assumptions, to include population projections and commercial/industrial activity and land use, in order to determine future service requirements. The City of Denton population projections are provided by the City?s Planning and Development Department. This data is adjusted annually to reflect any changes necessary that may affect the population estimates. The City of Denton Planning department growth rate projections are generally used to project City of Denton population growth through the next 20 years. Although Water, Wastewater, and Solid Waste each use the City of Denton population projections as one factor in developing the forecast, each utility has its own distinct service area. This results in different assumptions for the service area population and percent of population actually served by an individual utility. Exhibit I provides a summary of the Water utility forecast. The new Water forecast reflects only minor changes from the previous forecast. Major points include the following: Denton will need 100% of its raw water rights from Lake Ray Roberts and Lake Lewisville in the 2012-2013 timeframe. Staff will continue to evaluate options from new sources of raw water, including activation and renewalof the existing Dallas raw water contract. Additional treatment plant capacity will also be needed in the 2012-2013 timeframe. The current plan is to expand the Lake Ray Roberts treatment plant from 20 to 30 MGD. Based on recent data, gallons per capita per day (gpcd) continue to be below 175 gpcd. The reduction in per capita does not change the estimated 2012-2013 timeframe for the Lake Ray Roberts treatment plant expansion. Raw water supplies and treatment capacity are estimated to be sufficient to meet Denton?s needs for approximately 7-8 years. However, significant improvements to the distribution system will be needed to insure the additional treated water capacity can be delivered to the ultimate customer. AIS ? Council Agenda Item April 11, 2006 Page 2 of 3 Exhibit II provides a summary of the Wastewater utility forecast. The new Wastewater forecast reflects only minor updates to the previous forecast. Significant points are as follows: All projects mandated by EPA Administrative Orders in 1999 and 2001 related to wastewater overflows are complete ahead of schedule. Since completion of the additional influent raw wastewater pumping capacity at the Pecan Creek Water Reclamation Plant and the infiltration/inflow related projects, there is significant reduction in the number and volume of overflows in the wastewater collection system during wet weather events. The projected wastewater volumes thru 2025 show that additional wastewater treatment capacity in the Hickory/Pecan/Cooper Creek Basins is needed by the year 2020. However, the peak wet weather flows reaching the plant will exceed the raw influent wastewater pumping capacity. Additional raw influent wastewater pumping capacity will be required at the Pecan Creek plant to eliminate wet weather induced overflows in the collection system. The in-house update of the wastewater collection system computer model shows the Hickory Creek Pump Station serving the entire Hickory Creek Basin will be adequate for the upcoming 5 year CIP horizon. This may change if the 3500-acre Cole Tract development project starts selling homes within 2 years and undergoes accelerated development. Flow monitoring in the Hickory Creek Interceptor and at the pumping station will provide data on timing of the wastewater improvements in the Hickory Creek Basin. Options for initiating wastewater service in the Clear Creek/Milam Creek Basin have been developed. Implementation of one of these options will provide wastewater service in this sewer basin and may move back the construction of the Clear Creek Water Reclamation Plant to 2011-2012 time frame. Final resolution of Craver Ranch issues may alter the Clear Creek Plant schedule. The Solid Waste Department?s projections of municipal solid waste weights and volumes are based on the projected population forecast using a waste generation rate of 5.9 pounds per person per day. Current municipal solid waste projections are for the City to landfill approximately 112,010 tons of refuse during 2006 and 117,835 in 2007. The 2006 and 2007 projections are based on the following sources of waste delivered to the landfill. 2006 2007 Residential 23,499 24,898 Commercial 79,248 83,210 Delivered 9,263 9,727 Total 112,010 117,835 The City?s landfill has a projected site life through the year 2040. The increased site life is based on several assumptions: The continued use of alternate daily cover will reduce the amount of soil applied used for cover. Reducing disposed waste volumes by continuing to divert materials from the landfill through the City?s recycling programs.
