<br />I' <br />1,1 <br />II <br /> <br />I' <br /> <br />il;1 <br />I <br />I <br />I <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />fl <br /> <br />little attention to environmental protection and recommended conservation practices. <br />This creates and compounds soil erosion, sedimentation, water pollution and flood- <br />ing problems. Too often, representives of local public agencies approve such prac- <br />tices; and, apparently, they do not recognize and appreciate the severity of the <br />problems being created until they are reality. <br /> <br />It is possible to "plan" the development of large tracts in such manner that <br />disturbance of natural resources is minimal. For example, in forested areas, <br />buildings and other constructed improvements can be located far-apart so that "mini- <br />forests" may be preserved between structures. This provides habitats for wildlife <br />and retains some of the oxygen-generating capacity of the forest. Existing land <br />slopes can be retained with little disturbance, and major streets and components <br />of the piped drainage system can be designed to follow land contours. Existing <br />land cover should be removed only in areas that are to be built-upon within the <br />current construction season; and vegetation should be restored upon completion of <br />major work items. Local governments in some urban areas demand such practices. <br />Examples are Fairfax County, Virginia and Montgomery County, Maryland. <br /> <br />Land Developers -- Interaction with Public Agencies <br /> <br />Owners of floodplain lands are now having more difficulty in developing their <br />land. In many communities, uses of floodplains are now limited to such things as <br />ballfields, golf courses, parks, forest and wildlife preserves, nature centers, <br />bike trails, and other open space uses. Developers are no longer able to ignore <br />the adverse effects that their developments might produce. They are now required <br />to adhere to local land use regulations and ordinances that require stormwater <br />detention and runoff control. <br /> <br />Some developers and land owners may, at first, feel that local stormwater pro- <br />grams, laws and regulations will affect their profits and values adversely. Before <br />arriving at this conclusion, several factors should be taken into consideration. <br />If these laws and regulations were not enacted, much of the floodplain and flood <br />fringe lands would have little use. In this sense, the regulations aid developers <br />and property owners. Another matter that should be considered is the relatively- <br />low cost of stormwater detention facilities which are sometimes offset by other <br />factors. For example, where a permanent pond is required for stormwater detention, <br />the developer can sometimes recoup the cost of the pond by adding a premium to the <br />price of all units with a lake view, or frontage. Another consideration is that <br />the use of reservoirs is designed to delay runoff to downstream properties; and <br />developers might reduce storm sewer costs by using smaller and less expensive con- <br />duits. These arguments are helpful to municipalities when negotiating stormwater <br />control requirements with developers. <br /> <br />One plea made by land developers is a request for uniform treatment and con- <br />sideration by public agencies. They also emphasize their desire for land develop- <br />ment standards that are flexible enough to permit innovation and creativity in <br />design. Experience has proved that land developers do not object to regulations <br />and control--provided that they are stated clearly, easily understood, and appli- <br />cable to all developers of land, without exception. Land developers interviewed <br />in several areas of the United States stated that they favor strict subdivision <br />regulations provided they are reasonable, realistic and enforced uniformly. Devel~ <br />opers seem willing to accept new requirements, provided information is given them <br />prior to land purchases. They also feel that all developers in an area should be <br />required to follow the same rules. Drainage requirements can then be included in <br />the estimated cost of land development, and a developer can compete on the same <br />basis as others. <br /> <br />15 <br />
