By identifying, protecting and preserving those areas with ecological value, further loss of our natural heritage can be avoided." While Denton is a great place to live and work, part of what defines the quality of live in Denton is ready access to open space, both in the City and in the many recreational opportunities nearby. In addition to the quality of life benefits, open space provides wildlife habitat, assists in cooling the fierce heat of the Texas summer, improves air quality, cleans and filters water, and assists in flood mitigation, The Importance of Parks and Open Space: . Natural areas provide opportunities for passive recreational activities such as hiking and nature studies, while trees provide shade in parks for sitting areas. . Quality natural environments and open space amenities have become key decision making factors in the location of employers, as they try to attract workers, . Access to parks and open spaces, augmenting a place's quality of life has been shown to add to real estate values. . Landscaping with trees, shrubs and perennials minimizes the need for mowing grass and conserves energy and money, . Natural areas provide habitat for a diversity of flora and fauna - conserving and protecting species diversity. . Plants play an important role in recycling of carbon, oxygen, and nitrogen compounds in the atmosphere. . Trees and shrubs are essential to soil development and protect streams and other watercourses from erosion. . Plants improve the quality and supply of ground water slowly releasing moisture into the water table from root systems. . Trees improve air quality by removing airborne pollutants through their leaves, . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Because of the many critical roles open space can plan in our lives, it has come to be referred to as "Green Infrastructure n. "Green Infrastructure is our Nation's natural life support system - an interconnected network of waterways, wetlands, woodlands, wildlife habitats, and other natural areas; greenways, parks and other conservation lands; working farms, ranches, and forests; and wilderness and other open spaces that support native species, maintain natural ecological processes, sustain air and water resources and contribute to the health and quality of life for America's communities and people."

This plan provides the framework by which Denton may pursue more specific actions to preserve environmentally sensitive lands and open space. The residents of Denton have clearly articulated their desire to retain open space and the unique character of the region. This plan is meant to build on the foundation laid by the Denton Comprehensive Plan, and the Denton Development Code. Open Space in Denton Today Currently, of the 40,950 acres of the Denton City and ETJ, 3,030 acres are in public ownership of which 1,400 acres are in parks or protected open space. Another 18,000 are vacant, privately owned lands that are undeveloped today. It is on these lands that future development will occur, and where opportunities for new open space exist.

Public Ownership The Denton Parks and Recreation Department currently maintains 28 parks, open space and hundreds of acres of yet to be developed land designated for parks. This inventory ranges from active, full-service facilities, such as North Lakes to the public green surrounding the Courthouse. Through the Greenbelt Trail, the City has also realized huge successes with parkland that is utilized in a natural state. In addition, the City has developed an extensive system of bicycle trails and has begun a more comprehensive pedestrian trails system including rail trails, equestrian facilities and greenway trails. Today this extensive inventory includes 23 parks and 4 open space preserve areas, totaling just over 1,200 acres of land. Parks We all know that parks are important to people. Not only do parks provide a respite from the noise and bustle of traffic and crowds in cities and towns but they also provide the stage for a whole range of social activities. Parks, as a distinct type of open space, are publicly owned recreational areas. They may be a few acres of playing fields, or hundreds of acres of natural areas for hiking, or passive recreation, or a combination of both. However, they are meant to be used by the public, and have open access. Open Space Open Space is a more generic term that includes parks, but also private areas that provide some of the benefits of open space. Therefore golf courses and cemeteries can be considered open space, as are privately owned farms or ranches that have been conserved through purchase of development rights, or natural areas that are privately owned, but similarly conserved. These latter, privately owned open space areas provide many public benefits, without the benefits of entry by the public, but also without the tax burden of ownership and maintenance. One of the most important issues of urban development in the coming years will be identifying and managing areas that have environmental and social importance. Historically, environmentally sensitive areas have been destroyed, in the name of 'progress'to make way for development. Wetlands have been filled, streams buried turned into culverts, and lake shore areas filled and reclaimed. However, in the last few decades, the people of Denton have become increasingly aware of the value of a healthy natural environment and open space. . ,. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Floodplains & Riparian Areas "Riparian" refers to those areas that are adjacent to streams and lakes; often, it is also used to refer to floodplains, wetlands and natural habitat found within those areas. Riparian areas are beneficial to water quality when they are preserved and when the streams are lined with natural vegetation. These areas, especially when vegetated, provide stream bank stabilization and filter and retain storm water flowing across the stream buffer, thus helping to retain channel location, reduce flood potential, provide important wildlife habitat and help to keep streams and surrounding areas cool. The Denton Development Code classifies these as the areas within 100 feet from streams that drains over a squarc mile in size, and 50 feet from streams that drain less than a square mile. These streams, and the point at which the stream drains less than one square mile are on the official Environmentally Sensitive Areas map. The Denton Code also works to protect these areas by providing property owners and developers with significant incentives to transfer development densities away from riparian and floodplain areas. However, some of the larger riparian areas and floodplain have such large significance for open space values, they should be considered for open space acquisition, for drainage and flood control, habitat preservation, air quality benefits, and passive water quality treatment. Some of these areas would also provide passive recreation opportunities such as hiking, fishing, or canoeing. Water related habitat lands are farther from the stream, but occupy important floodplain areas and contain generally undisturbed native ecosystems and wetlands important to the stream health and the community's air and water quality. In Riparian and Water Related Habitat lands, Lands, most development activities are prohibited. The intention is to leave these areas in a natural state, including most of their native vegetation. This benefits many elements of Denton's environment, most notably air and water quality and flood mitigation. Floods have been a problem in Denton's urban areas for much of its history, as some of the best places to build in town often are the floodplains of Pecan Creek. In addition to preventing property damage, restricting development in floodplains serves many other important functions. These include water recharge, protection of wildlife riparian habitat, and floodwater storage. The Denton Development Code has fairly strict development limitations on development in floodplain. There are just over 3,000 tax lots that lie partially within the lOa-year floodplain, with roughly 600 of those parcels being completely contained within one of Denton's many, floodplains. As a result a significant number of housing units and many businesses already have located in the floodplain, including some of Denton's most urbanized areas, such as the downtown with Pecan Creek running right through it. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Cross Timbers Oak land Cross Timbers oak areas are unique upland habitats to the Denton area. The ones considered significant for open space values are generally larger than 10 acres or more and support a unique upland ecosystem. Standards in the Denton Development Code in these areas require that at least 50% of the habitat in these large stands be conserved. Approximately 75 percent of the Cross Timbers and Prairie vegetation areas are utilized as range and pasture. Major crops on the sandy Cross Timber soils are peanuts, fruits, sorghum, wheat, oats, com, and forages. Dairy operations are common, but beef cattle cow-calf operations are the predominant livestock activities. Agricultural lands Agricultural lands are valued in Denton for many reasons ~ their beauty, their contribution to the economy, and their value as open space and buffering from other uses. Agricultural lands protection often is controversial, frequently because agricultural issues are poorly understood. An important aspect to consider when discussing agriculture is that it is a business and, as with any business, profit is essential for its continuance. Residents who move onto agricultural land because of its pastoral nature often are disturbed by the necessities of modem agriculture: around.the.clock harvesting, manure spreading, pesticide and herbicide spraying, and the presence of strong odors and flies. Meanwhile, suburban residents can disrupt the business of agriculture by clogging roads with traffic, making the transport of agricultural equipment difficult and hazardous, owning animals that harass livestock, and filing nuisance complaints against farmers. In agriculture, it also is important to understand that a farmer's land is his or her primary capital asset after a lifetime of work. Urban residents value the open space that agricultural land represents, but zoning that restricts land use to agriculture only is often resisted by the farmer if the land can be sold for urban uses. as that will maximize the return to the farmer. In Texas, where county zoning is not permitted, agricultural land protection can best be accomplished by either transfer of development rights or by the purchase of conservation easements, or agreements in lieu of annexation. (See Implementation Chapter for specifics) Other Wildlife Habitat Important wildlife habitats include prairies and riparian areas as well as forested areas such as the Cross Timbers lands. Many species' existence depends on the continued health and connectivity of these habitats. White.tailed deer, raccoon, armadillo, squirrel, quail, and mourning dove arc just a few examples of the abundant wildlife in the regIOn. ,. _' _ .

Setting Priorities Thrcats to Opcn Space With the hundreds of thousands of acres of open space that are in and around Denton, a system of prioritization must be established to identify those lands that are best suited to protection. Utilizing the power of Geographic Information Systems (GIS), computer-mapping models have been created to assess the threat and resource values of these lands in and around Denton. This computer model is built into two distinct parts. The first model analyzes the resource potential of all the land, while the second calculates potential threats to these resources from development. Together, these components are brought together to determine that land that is both of most resource value, and that is most threatened. The result is a mapping of areas with the mathematical highest priority for protection, preservation, or acquisition.

Undeveloped lands Land areas that have yet to undergo significant human alteration are more valuable as open space for numerous reasons. Of utmost importance, conversion to open space can be accomplished without any displacement of human settlement, helping to ensure that no individual resident is forced to take on an undue burden for the good of the rest of Denton's residents. Additionally these lands will be both cheaper to acquire due to lack of development and more likely to contain habitat and natural areas that are considered valuable as open space. Environmentally Sensitive lands Many of the key habitat and open space resources occur on lands identified in the Denton Code as Environmentally Sensitive Areas. In determining potential value of open space, Floodplains, Riparian Habitat and Upland Habitat are key factors. These areas contain not only areas that are likely to be relatively undisturbed, but also areas that feature prime habitat for a number of species. Preserving these lands can playa crucial role in retaining diversity of species. Residents will also reap the rewards of protection through such issues as flood control, lower temperatures in the summer, better air quality, and access to both the natural areas and potential trails that might be run through these areas. These lands are not as valuable to land owners, as the building potential is lower; accordingly, as with undeveloped land above, these areas will be less expensive than developed, or easily developable areas. Threats Leading to Loss of Open Space Proximity to roads and service The Proximity of open space to infrastructure can help to estimate how threatened a specific site may be. If there is already infrastructure in place, such as roads and sewer, then an area is likely more susceptible to new development. By recognizing these areas, and those where services will soon be extended, a potential threat from development can be identified. Future Population or Employment Concentrations The zoning types in the Denton Code carry much detail, ranging from landscaping to allowed uses. Paramount to Open Space planning is the land use, and subsequently the intensity of future development. Further, while not proscribing zoning for areas outside the city, but inside the ETJ, the Denton Comprehensive Plan provides an estimation of the expected future development density. Densities were analyzed in a gradient fashion, with highest densities having the most potential threat to open space resources. This calculation of likely future was used in conjunction with the proximity of roads and services to determine the combined potential threats from development. Access to population The current Denton parks system serves most of the population with parks within y., mile walking distance. This is quite a high standard for the provision of open space. New development, however, will need to be served with additional open space outside the existing City Limits. In addition, completion of the system of trails within the city should remain a high priority as this contributes the interconnectivity of the overall system of open space as well as to accessibility to a wider population. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Working toward Consensus - The Denton Open Space Workshop On February 27, 2002, the City of Denton sponsored an Open Space Workshop to help draft a plan for the Denton region. The workshop was designed to help develop both a priority list of sites for the Open Space Network, plus recommendations on methods necessary and a decision making structure to help decide future questions of open space need. The workshop process enabled participants to choose which areas they felt should be of the highest priority and give valuable input about the future of Denton's open space. Participants worked in two small groups to create alternative plans, and those plans were analyzed. The plans were then synthesized into one final conceptual open space plan that incorporated all the key themes and ideas presented throughout the workshop. The workshop resulted in an interconnected open space system featuring continuous trail linkages among the existing and proposed open space acquisitions. The workshop provided numerous specific ideas for the enhancement of the open space system that will form the kernel for its expansion. Most of the ideas are applicable to the wider landscape and can be interpreted Open Space Plan - Introduction Key Plan Elements The plan includes the primary elements that are described in the following discussion. As a plan, the map should be interpreted, not as a parcel- specific plan, but rather as a guide to a conceptual open space master plan. There is considerable flexibility among the component parts in terms of implementation. Conservation sites may ultimately be acquired or dedicated as open space through the development process, and acquisition sites may be partially developed in exchange for public ownership of key areas, but it should be a guiding document for the development of a comprehensive open space system in Denton.

Trails or Trail Corridors The Community Trail Network Trails are to be both regional and local in scale and should provide potential destination oriented trips such as work or shopping while also providing a recreational component. Trail networks are identified that establish new, or that enhance existing, regional and cross town routes, connecting major centers of activity with non-motorized routes, Additionally, enhancing the pedestrian connections along local and regional transportation routes also is important. A variety of trail types allows for many different uses. For example, a good trail system employs both hard and soft surfaces. Hard surface trails are generally for use by walkers, skaters, bicyclists, and people with disabilities, These trails are the ones which will serve both recreation and transportation functions. Unlike the hard surface trails, which might start off as natural and only later be paved when funds are available, the soft surface trails will serve the Denton's nature preserves and other areas where the focus on natural resources takes precedence over the need for mobility. In addition to pedestrian-only trails through sensitive natural areas and off-road bicycle trails in less sensitive ones can provide both important access to Denton's Open Space and important transportation links. Denton currently has a trail network that runs just under fifty miles in length. The most notable of Denton's trails are the Ray Roberts Greenbelt connecting the City from Lake Lewisville all the way to lake Ray Roberts, and the more recent Rail to Trial conversion extending Southwest from Downtown Denton to beyond the city limits. Many of the drainages within town, such as Pecan Creek for example, have many places where "Volunteer" trails have been created to supplement the official trail network. These "Volunteer" trails are a result of people walking or biking over the open land, in essence showing us where they would like the improvements. Additional unofficial trails can be seen at North Lakes Park. Regional Parks Regional Parks are places for recreation, education and rejuvenation and provide for a vast array of native fish and wildlife. Regional parks are unique jewels featuring sensitive habitats, awesome landscapes and views, trees, heritage buildings and sites and basic facilities. The North Lakes Park off of Bonnie Brae Road, just North of University Drive is a shining example of a Regional Park. It offers a range of recreation alternatives and serving residents from all parts of the city with its ball fields and courts, Community Recreation Center, Trail and wildlife to name a few attractions, North Lakes Park is also well positioned to serve a future expansion of population to the north, running up to and just past Loop 288. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Ecosystem Habitat Many of the habitats in the Denton region have been degraded over the past decades, and in some cases permanently altered, by urban development and sprawl. Protecting and restoring these habitats requires an understanding of comprehensive ecosystem function and all the interconnections that combine to support the health of any particular habitat. An ecosystem approach to management habitat recognizes the interrelated nature of air, land, water and all living beings. Rather than geopolitical boundaries and departmental divisions, this approach calls for creative partnerships that look at natural boundaries, such as watersheds, as the unit of management. Participants at the workshop identified several areas important for their quality ecosystems and amount, or diversity of habitat. One of the highest ecosystem priorities identified is the Hickory Creek drainage, stretching from Lake Lewisville up to at least 1-35W. At just about the same level of interest to the group were the Pecan and Cooper Creek drainages. As these two streams get closer to Lake Lewisville the amount and diversity of habitat increases, while at the same time there is less human alteration visible. ;O;:,Q' ;i!f! ~., ""-',,~~' .r'~~~S'~'" ~ 11Y I "-'ii. ~i~J.~,~'w.":tW~W~~~ ~'Jr~~~"- ""'.: .' ~1 d!l!'Y "'K"""i),~"ll~"P~ ~ <r,,,,,.,' ~" . .;~~ W'G;". ..'l~... .;j;i,'" .;r~..U,l.~' - .~. ....., {fl.'"}..;' ~.J'S.. 1;/r-:.iG: .Ii. ft:!' \, ,. .

Access points along the corridor make it possible for residents and visitors to experience these areas through hiking, horseback riding, biking, nature studies, bird watching, scenic viewing, picnicking, and more. Scenic corridors are generally described as "the view from the road" and can best be defined as the visible land area outside a road right-of-way. They vary in width according to topography and vegetative cover; flat open areas will have wider corridors than steep, narrow canyons or densely wooded areas. Denton's most popular Scenic Corridor to date is the Lake Ray Roberts Greenbelt, providing access for hikers, bikers, horses and even canoe and kayakers. Participants saw much value in continuing this greenbelt South, to and along Lake Lewisville with an eventual connection to the existing Rail to Trail conversation leading Southeast from town. Additionally much support was shown for a new scenic corridor connecting the Greenbelt to Sherman Drive along Clear Creek. Criteria for Delineating Scenic Corridors Angle and Duration of View The angle at which the landscape features may be seen from the roadway, in both directions of travel, the foreground features framing them, and the period of time they can be observed all bear on the delineation of the corridor and must be taken into consideration. Topography When landforms, such as the crest of a ridge bring the range of vision from the roadway close to the right-of-way, the entire visible area should be included in the corridor. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Priority Locations Urgent Environmentally sensitive land that is under immediate threat of development is the highest priority for consideration. An evaluation of potential codes that might protect the critical resources is the first stage. This will establish the basic core that can be protected under regulatory processes. Secondly, the proposed development design should be reviewed to evaluate the degree to which it accommodates other resources that are present on the site. There are often possibilities for improving the sensitivity of the design in the context of the existing resources. Typical Urgent Sites The following are general locations and represent types of open space areas that indicate the highest priorities for consideration. These locations were identified because they are important open space resources, such as flood plains, riparian areas, historic and cultural locations, and/or environmentally sensitive areas. lower Reaches of Hickory Creek The Hickory Creek green-belt area flows southeast toward its confluence with Lake Lewisville. With much prime habitat and its close proximity to residents in the southern portion of the city, Hickory Creek is a valuable for habitat protection, trail potential, and access to nature. Preservation of this corridor is also vital for pollution control. Much of this area is currently owned by the United States Army Corps of Engineers. Land owned by the Corps can often, and should in this case, be protected through public easements. The use of easements being much more economical than outright purchase, and the unique ownership situation both make this site a distinct short-term possibility. The City has had success to date in signing agreements where the city will agree not to annex the property, if the owner declares that he or she will not develop the property to urban levels. Agricultural and Ranch lands These lands have cultural value as well as being fine examples of quality prairie land. These lands would be a valuable asset as a regional park combining a fine natural environment with large areas that could be developed as recreational facilities. It could also support prairie restoration. These lands could be considered prime for development due to their size and location in Denton. With a relative lack of environmentally sensitive areas, properties such as this are may prove to be very expensive to acquire. Unfortunately, sites of this size are not very useful if only small easements are purchased. Therefore this type ofland tract would likely have to be purchased outright with public monies. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Historic and Cultural locations In addition to agricultural and ranch lands, there are other land areas that hold significant cultural value to the Denton community. Thesc locations may be unique land formations and/or locations of historic events that have become icons to the Denton area and should be protected or preserved. Clear Creek Natural Area Just Northeast of the city limits Clear Creek flows toward the East through some exceptionally well- preserved lands. Acquisition of lands in this area can provide a full array of benefits, ranging from trail linkages and access to nature to habitat protection. Sites such as this can also be excellent locations for interpretive centers. The most urgent targets should include areas most likely to be affected by development first. Currently this is the most eastern sections of Clear Creek. Preservation of this entire corridor is also vital for pollution control. Pecan and Cooper Creek Drainages These two roughly parallel drainage ways were highly valued by the participants at the workshop. Running from Loop 288 to Lake Lewisville, these corridors provide key trail linkages, important access to open space, and preservation of important habitat. These areas are unlikely to be host to any significant public facilities or destinations and therefore are likely best candidates for protection through easements, with outright acquisition as a last resort for any gaps that occur.

Near Term Sites that are zoned for high intensity development should be carefully monitored for any indication of imminent planning applications. Any available information on the type of proposed development, number of units and resource lands that might be compromised should be ascertained as soon as possible. Early negotiations with the landowner should address the most valuable resources on the property and potential for protecting or conserving these. Potential acquisitions should also be considered, if the developer is willing to consider this as an option. Additionally for larger developments easements or ownership may possibly be obtained as either an exchange for park fees, or to alleviate the property owner's liability on land that he or she leaves undeveloped. Near Term Sites Include: Upper Reaches of Hickory Creek Hickory Creek flows southeast toward its confluence with Lake Lewisville. The lower reaches of this stream corridor have been identified in the "Urgent" section as a top priority. The upper reaches would make an excellent addition to the previous piece. Adding this stretch will allow the City to build on the trail network, protect additional habitat and provide more public access to open space. This trail could rival the Ray Roberts Greenbelt as an amenity for Denton's residents. Unlike the lower reaches, the ownership patterns in this stretch are more complex. While there should be potential for utilizing easements to grant public access there are likely to be situations where outright purchase will be necessary. Also like the lower reaches, agreements in lieu of annexation may also be employed. As with the lower reaches, pollution control is also an important motivator in protecting this property. Milam Creek Tributary Roughly paralleling Locust at the northern edge of town is a tributary of Milam Creek. Water from this creek ultimately flows into Clear Creek. As trail linkages are established along Clear Creek, this site could be added to the inventory. A trail in this location would provide access in a growing portion of Denton, allowing many to access the greater trail system, including the Ray Roberts Greenbelt without needing to drive. Additionally this site could provide additional access to nature for the new residents that will be living in the area. This is a smaller creek, draining less than one square mile. As a result, the riparian and floodplain protections are less comprehensive than on other streams. Because of the lower level of protection, the parcels along this stretch are more developable than similar parcels along other, larger streams. The higher degree of developability will by necessity result in higher prices. While it may be possible to obtain some of this land through donation, much will need to be simply purchased, either outright, or as easements. Small sites such as this, which fit into more of a long-term vision, are often elevated in priority to suggest purchase early, before development pressure in an area begins to affect land prices. Fletcher Branch of Hickory Creek The Fletcher branch of Hickory creek flows from the southern end of town, due south until it reaches the Creek. Roughly halfway long this branch sits a large area of undeveloped land, roughly between Ryan and Hickory Creek roads. This site has much potential as an active park. Further, with the completion of the Hickory Creek greenbelt, this site could become a convenient access point to Denton's trail network. The branch itself provides potential as a trail linkage as well. While the trail portion may be accessible via easement, the land for the complex itself should be planned as outright purchase. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Long Range Larger tracts of land that are not zoned for intensive use, but which might be developed over longer periods of time should be considered for environmental overlay zones. Using the tools currently in the Denton development code relating to transfer of development rights, some of the sites available for rural density development could be configured as conservation developments. This style of development clusters rural housing while maintaining conservation easements accessible to all adjacent landowners. These areas could be restored as prairie, maintained as riparian areas, or set aside as wooded preserves in the context of the overall development. An environmental overlay could be inclusive of many separately owned tracts of land, which could be addressed individually as development occurs. Complete Trail Network The majority of the scenic or waterway corridors listed in this report are intended to be accompanied by trails. As these areas are protected the City will find that it has a truly unique opportunity for a connected trail system both throughout the city and beyond to Denton's natural areas. Most of these trail sites will be acquired through the sites listed in this report. However, there will no doubt be areas where gaps will occur. In many cases, the City may have to purchase land or easements necessary for completing this system. The City may also choose to use nearby roadways to link trails that are otherwise not linkable. These trails may also be acquired through donation at times of development. The trails, fundamental to this Open Space Plan are shown in detail on the accompanying map. ~.

Scenic Corridors Much support was shown for a new scenic corridor connecting the Ray Roberts Greenbelt to Sher- man Drive along Clear Creek. Unlike many of the targets in this plan this area is not intended for trails or habitat preservation. This corridor is intended to provide an elegant corridor for autos entering and leaving Denton. Methods of protection will vary, and the standard is not as high as in the waterways. Not all development needs to be precluded; this area could even be home to some clustered rural housing without crossing the intent of the scenic corridor. This roadway will function as a natural gateway for travelers. Much of this land is not currently within the City of Denton's jurisdiction and would require extensive partnerships with other government entities and private landowners. Far Northwest Neighborhood Parks There are currently a number of large, undeveloped tracts ofland in the far northwest area of the city. With their connections to Milam, and ultimately Clear Creek, this area could provide an excellent access point to Denton's network of trails. The large size of the sites, along with their proximity to expected future development give it much potential as a location for one or more neighborhood parks. This land would need to be obtained through outright purchase, but may be aided by parkland dedication, and fees in lieu of land for nearby developments. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Northwest Urban Trail Much future development is expected near the intersection of Loop 288 and 1,3SW. Along with, or prior to this development a trail system should be put into place. The route could be roughly circular connecting both sides of each major roadway to each other and to the trail network located to the east. The precise location should be determined through a localized process. Unlike many of the other trails mentioned, this trail does not follow any significant waterway. This means that donations or easements that may normally result from the need to protect the waterway will not apply. There may however be potential for donations of land during time of development. Easements may also be employed for this site. ~~....---/1~, '~_ .A,.-,..~Cl.r:~ "" --='.'..'''. ~~','--~,"",' ~ '''''''''',' " -.' ..~~....

This area, while not containing any significant stream related habitat, could be an important piece of open space for nearby residents. Workshop participants felt that this site would have to be purchased outright, but would be a worthwhile investment. = . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Unique or Opportunity Sites (dependent on availability) Occasionally particularly desirable sites become available for acquisition that would be of substantial benefit to the entire community. There are several examples of particularly fine sites that have the potential of helping define the community. These should be shepherded into public ownership using any appropriate tools to assure their protection for the community benefit. - Key Unique or Opportunity Sites Large Sites Containing Habitat Intensely zoned parcels that contain either water related or upland habitat should be examined for potential protection. Sites Containing Prairie or Park Potential There are several sites around Denton that while they contain quality prairie lands, are not being singled out in this analysis. This is partly because there is little to distinguish these sites from one another, and protecting all of them would mean using up a large portion of Denton's buildable land supply. However, thesc sites can play an important role. The areas inside the city are well served by neighborhood parks. As development occurs, monitoring other suitable sites in developing areas can help to ensure that the level of park service remains high. There is no general rule in terms of acquiring these properties. as each case may be different. Daylight Downtown Streams Several portions of Pecan Creek and its various branches have been placed underground. These streams are often referred to as the WPA drainages, as they were construction by the works progress administration. Many urban areas 'have begun experimenting with daylighting or bringing these streams back to the surface and usually adding trails. Sometimes this involves rerouting the stream, but more often channels are simply opencd up and the banks reconstructed. These streams can add beauty to an area as well as provide business opportunities such as outdoor cafes that are oriented toward the stream, and a trail along the side. Culp Branch This stream running near and ultimately into the Elm Fork of the Trinity could be useful for pollution control, access to nature, and simple preservation. Multiple methods of protection could be employed, but will likely involve either acquisition or easements. This stream, especially just prior to the confluence was highlighted by the workshop participants. Many such similar situations may arise as development or even further study brings additional areas into the spotlight. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Land Protection Tools and Techniques Acquisition Of all the implementation techniques, this is the most flexible, and allows for the permanent ownership of land, the full right of access by any public member, and the full rights of management of the land in the public interest. It is also the most expensive, not only for the purchase price, but the land is removed from the tax roles, no profitable enterprise is conducted on the land, and it then becomes a public burden for maintenance. Since it involves direct expenditure of public funds, this tool is one that should be used sparingly, and only for sites that cannot be protected in any other way. There are special sites that should be protected, regardless of the cost, and this should be used as a final resort to assure their preservation. Therefore, this tool should be used selectively, in areas where either public management is needed, or public access is important for the purpose of the park to be achieved. City park funds - fee in lieu of dedication Money is placed in the general park fund through fees on new development. Large developments will usually be creating their own parks to address their localized needs. Smaller development, and large ones in certain instances provide money in lieu of parkland dedication. Bonds Approved by voter referendum, General Obligation Bonds may be used to finance acquisition, easements, or construction. These bonds are most often used when the project will not generate enough revenue to cover the cost of the improvements. Revenue Bonds are also useful as they can be used for projects that will eventually produce enough income to cover their debt. Regional parks are examples of sites where Revenue Bonds can successfully be employed. City drainage funds The City has recently implemented a new surcharge on property to enable compliance with the clean water act, flooding, and other problems associated with runoff. The drainage charge is calculated for impervious surfaces on properties. Impervious surfaces represent surfaces that contribute runoff into the storm water system including the basic building structure, garages, roofs, patios, driveways, parking lots, etc. Many of the improvements associated with protection of stream corridors may fall under the auspice of the purpose of the drainage fund program. Open Space Bonds Funded by Property or Sales Tax Several places around the country have found success in acquiring public funding for important open spaces by going to the ballot box. Austin's Proposition 2 "was a Smart Growth Initiative designed to steer dense development away from environmentally sensitive areas by using City funds to purchase, either in fee or through conservation easements...." (Executive proposal summary/ Remarks of Mayor Kirk Watson settlement agreement between Bradley Interests and City of Austin). Of key importance in asking voters to spend additional monies on open space acquisition is to clearly identifY what the public will receive for the money it spends. A balance must be made however, in terms of how much detail is provided. If individual parcels are listed the initiative can be perceived as targeting some individuals over others, and more importantly, can possibly create inverse condemnation problems that may result when the owner's property is suddenly less valuable to developers as a result. Experience has shown the most successful initiatives stress the overall goals of the project, and simultaneously provide both target amounts ofland and rough generalized locations with a fair and equitable distribution. ~'" ~~!i "Ji""-;f' y" ~:;:" ~- , """ '13. ,'" " " ;;;' , ,,~,~ "'" ~.... - '-' "~~8"- PI' ","",~ "",-..

Agreements in Lieu of Annexation The City of Denton has achieved some measure of success in signing a contract with a landowner where he or she will agree to not develop the property to urban levels in exchange for the city passing over the option to annex the property. In cases where conservation, not access is the goal, these agreements may be employed. Land Exchange Public entities occasionally have properties that are of suitable size and location to make them attractive to be traded for private lands desired for open space. Land exchanges are done on the basis of appraised value rather than size. Land trades can be time- consuming and complex but can be beneficial to both the seller (no tax for an equal exchange) and the purchaser (no cash required). Under federal and state tax laws a landowner may exchange one tract of land for another. An advantage of such transaction is that capital gains taxes are deferred. For example, the swapping of privately owned land with conservation value for publicly or private nonprofit owned developable land. Acquisition of Development Rights (Conservation Easement) Transfer of specific interests in land (rights) from a landowner to another party. For example, an easement may specify that all or part of the land be left in a natural state through the transfer of all or limited mineral rights, timber rights, subdivision rights, etc. It may allow restricted or unrestricted public access. The landowner may retain ownership and specified reserved uses, while the easement holder has the right to enforce restrictive conditions included in the easement. Appraised value and, therefore, property taxes and estate taxes, are routinely reduced in proportion to the reduction in land value when an easement is donated to a government agency or private nonprofit organization. Easements must be in perpetuity to qualify for federal and state income tax advantages. Regulatory Protection Density Transfer (already established in Denton Code) One of the most effective regulatory provisions in mitigating reduced land values is a density transfer system. With density transfers, a property owner has the right to the same number of units and allowable uses, but the units are transferred on the same parcel from more sensitive land to less sensitive land. With density transfers, the economic effect of environmental protection may be almost benign - especially in residential developments. The focus of a density transfer system is more on how to design with nature, rather than how much to diminish the overall development intensity. We recommend that density transfers be permitted as a property owner's right and not subject to approval through a discretionary decision-making planning process. No action is needed to implement this section, however, developments that occur in areas that have been identified, as key open space areas should be encouraged to use the density transfer provisions to their fullest extent in order to facilitate the implementation of this plan. Transfer of Development rights One method that has been used to protect open space lands is a Transfer of Development Rights (TOR) system. Several states throughout the nation have TOR programs that are two decades old or older. In a TOR system, the area to be protected is designated as a "sending zone," in which a certain number of units per acre are credited to the sending area. A "receiving zone" also is set up where the development rights can be transferred. By buying the development rights from a farmer, a developer can achieve a higher density in the receiving zone than otherwise would be permitted. The beauty of a TOR system is that the compensation amount is determined privately between the property owners involved-and the result is permanent protection of the farmland. Accompanying this document is an appendix that contains a Transfer of Development Rights ordinance that can be added to Denton's development code. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Summary This list of strategies is not exhaustive as other programs may be available that have not been brought forward. Strategies noted may be modified or used in combination. The overriding theme is that no one strategy will be acceptable to all property owners nor provide the right mechanisms for achieving the goals of this plan. A number of strategies are listed as it is recognized that it will take a number of different ones working together to be successful. While certain areas have been targeted as examples for a particular strategy, this is not intended to limit the tools that may be brought to bear to achieve the goals of this plan. _~:-~'?"V. ,c;"----Y-'''- ,-';-----:-;-"f:'-::--..~. lTd:;"~ '''"',",7"''' .r1~kd~_~":..r... ,~..'\\"{~~)~:'" ~).

'\ Conclusion This plan is intended to further this vision of the plan, and lead to specific action that will lead to a Denton that is as good as, or even better, than the ,place we live today. One thing seems certain to the people of Denton - if we build a successful economy, an efficient transportation system, and a good education system but neglect open space, we will have failed. The public benefits of open space, in its various forms, may range from aesthetic appreciation to food production and recreational uses. These values contribute to the wealth of the region, boosting its economic, social and natural capital, and contributing to the long-term sustainability of the community. Open space, in all its forms, is not just a land use designation, but also a value in its own right, as well as having added value that is associated with other land uses such as agriculture and outdoor recreation. Open space also benefits public safety, preserves scenic resources, provides a buffer and delineation between developments and serves to protect wildlife and natural habitat. lt is these open space lands that serve as the heart of Denton's "quality oflife." ,.': . ~.,~ ~.~-
