Environmental Resources 12-8-06 Environmental Resources II.ENVIRONMENTAL RESOURCES All of the activities and investments that take place in the Town are closely related to the Town’s natural resources, from the land itself as a surface for buildings and roads, to the soils of the land, the water underground and above ground, and the plants and animals that inhabit the landscape. The Town’s transportation systems, economy, development patterns and potential development are all influenced by the natural features of the Town. In addition, the Town has an interest in preserving important natural features, for practical reasons, for aesthetic reasons, and for the sake of preserving biodiversity in the region. The Town is a relatively populous suburban center within the metropolitan New York region because of its proximity to the Hudson River. Although the river no longer serves as a primary mode of transportation, the plains and gradual hills of the river valley still contain most of the transportation routes and population centers in the area. The Town’s drinking water comes from bedrock aquifers through individual wells, and from subsurface soil and gravel aquifers that are part of the Wappinger Creek and Sprout Creek drainage basins.The relative impermeability of most of the soils in Wappinger has had an effect on the settlement pattern of the Town, limitingdensity through natural constraintson the proper functioning of individual waste water disposal systems (septic systems). Impermeable soils have also led to an abundance of wetlands in the Town, which present both barriers to development and opportunities for connected wildlife and open space corridors. The 2004 Town Survey showed that environmental issues are important to Town residents. With 96 percent of respondents rating the preservation of environmental resources as “important” or “very important,”it was the highest-ranked issue facing Wappinger today. Other highlights include: x 59 percent supportedtheTown using tax money to acquire undeveloped land to preserve and protect community character.Thirty-five percent said it was the single-most important investment the Town could make.Fifty-six percent would support a modest increase in taxes if this objective was achieved. (This objective wasthesecond most popular proposed use of tax money in the Town.) x Scenic beauty was one of thethreetop reasons why people choose to live in Wappinger. Town of Wappinger Comprehensive Plan16 Environmental Resources x 79 percent of survey respondents supported preserving open space resources as the Town continues to grow. x 50 percent favored conservation or cluster development of new subdivisions, versus20 percent opposed and 30 percent unsure or not responding. x Of the recreational amenities that respondents said they would like to see more of, nature preserves and trails were the two top items. “Nature enjoyment,” walking or hiking and picnicking were the three most popular activities chosen from Question 30 of the survey. x 69 percentsupported the Town actively pursuing the extension of a regional Greenway walking trail system along the Hudson River. Issues and Opportunities 1.Scattered land development throughout the Town has fragmented habitat. If effective regulatory action is taken, open space corridors can be preserved along the Hudson River, Wappinger Creek and Sprout Creek. 2.Opportunities exist to improve the protection of ridgelines, steep slopes, streams and wetlands through land use regulations and permitting procedures in the Town. 3.Relatively impermeable soils coveringmuch of the Town oftenresult in septic unsuitability, less rainwater percolating into the ground, and more wetlands. Ten percent of septic systems are failingor marginal, and these pollute surface water and groundwater. 4.There is a relativemismatch between thecapacity of theland to absorb waste water and theallowable density of dwelling units in the northeastern part of the Town. 5.Roadway and parking lot design standards, such as street width, width of right-of- ways, cul-de-sac turn-arounds, roadside drainage, and parking ratios all have an impact on the amount of impervious surface in the Town. For instance, unnecessarily wide street widths contribute to the creation of impervious surfaces in neighborhood subdivisions, which reduces water quality. Town of Wappinger Comprehensive Plan17 Environmental Resources 6.Poorly managed earthwork and excavation sites pollute surface water with silt and sediment.DECPhase II stormwater regulations are in the process of implementation in theTown.There is a needforstrict enforcement of regulations. 7.Road salt and water softener salts are sources of water pollutionin the Town. Careful attention to the methods and materials used for de-icing roads and encouraging the use of widely availableimproved technologies for water softening and purification can substantially reduce the water quality impacts associated with these uses of salt. 8.The Town is home to a number of threatened and endangered species, including theBlanding’s Turtle,and plants such as Blazing Star, Rattlebox and Violet Wood Sorrel. 9.The Town is a member of the Hudson River Valley Greenway Compact, which encourages inter-municipal cooperation and policies consistent with Greenway principles, including natural and cultural resource protection, public access, and environmental education. Membership gives the Town enhanced access to grants that help implement Greenway principles. Environmental Conditions Approximately one-third of the Town, consisting of about 5,000 acres, is currently undeveloped land. About 970 acres are protected as parkland or conserved lands, representing about 6 percent of Town lands. An additional 1,080 acres of wetlands are protected as habitat through NYS DEC regulation. The main topographic features of the Town are the Wappinger and Sprout Creek valleys. Central Wappinger is characterized by a mixture of large flat areas and low undulating hills typically rising up to 50 feet above the surrounding land surface. Lowlands along the Wappinger Creek define most of the western boundary of the Town, changing abruptly to steep slopesalong the Hudson River.Hills just west of Sprout Creek range along the eastern side of Town, forming the drainage divide between the two main watersheds in the Town.Elevations range from 540 feet at the top of Cedar Hill just east of Smithtown Road to near sea level along the Hudson River.Wappinger contains several long ridgelines; many high points with excellent panoramic views; and significant areas of steep slopes that provide scenic quality as well as severe constraints to development. Withtheexception of areas generally within the floodplainsofSprout Creek and Wappingers Creek that have sandy, gravelly and excessively well drained soils, most of Wappinger soils are characterized as poorly drained, clay and/or rocky. The result is that there is a very large and extensive system of surface waters and wetlands throughout the Town of Wappinger Comprehensive Plan18 Environmental Resources Town, and relatively little, or very slow, groundwater recharge in most areas of Town. Wetlands are extensive, interconnected, and essential to control of flooding, water quality, groundwater recharge and wildlife corridors. Pollution, contamination, filling or degradation of wetlands may affect neighboring communities, the environmental health of the ecosystem, and thequality of life of residents. The Town of Wappinger contains habitat for a wide variety of plant and animal species. Continued efforts are required to protect local plants and animals and their habitats, and to diminish the presence of invasive species in order to encourage biological diversity. Habitat fragmentation is a constant threat, particularly to animals that need large areas of habitat to sustain their activities. Currently, the deer population is considered a nuisance by many Town residents. Deerpopulations are cause for increased concern due to tick borne diseases such as Lyme’s Disease, and concentrated populations become a nuisance and safety hazard for residents and drivers. Under-story vegetation in wooded areas is being denuded and causing harm to the natural balance of native species. For more detailed information regarding baseline environmental conditions of the Town, please consult the companion volume to this Plan, Inventory and Analysis. Goal Encourage the preservation of environmentally significant features. Objectives and Recommendations A.Establish and preserve open space corridors along Wappinger Creek, Sprout Creek and the Hudson River, and improve access to these resources. Preservation of open space can serve several important purposes including: x Protecting and strengthening ecological functions; x Providing habitats for increasingly rare and endangered species; x Preserving community character; x Protecting lands for parks and passiverecreational uses; and x Providing economic benefits such as enhanced land values. Town of Wappinger Comprehensive Plan19 Environmental Resources Recommendations 1.Revisethe Town’s SubdivisionRegulations to require or encouragethat any areas established for open space be designedto connect with other open space parcels to form continuous open space corridors. 2.Enhance open space in and aroundRobinson LanePark, through possible expansionto adjacent undeveloped properties, and through connections to other adjoining open space resources, including: x Existing Sprout Creek trail system in East Fishkill; x Proposed Rail Trail on former Maybrook railroad line; x Further west to NYSEG rights-of-ways; and/or x 40-acre open space parcel with 3,000 feet of frontage along Sprout Creek in theBlackwatch Farm. 3.Increase connectivity of open space for passive recreation through public use of trails on utility easements and rights-of-ways. There are over 24 miles of such easementsinWappinger (see Recreation Areas map). Although some sections would not be appropriate to use as trails, such as where they pass through established subdivisions, other sections may be well suited to the purpose.In recent discussions with NYSEG, itsrepresentativesstated that they do not have objections to such use. 4.IntegratetheMaybrookRailTrail with theproposed open space corridor along Sprout Creek. 5.Considerin the future increasing the 100-foot buffer requirement for wetland and watercourse buffers in proposed open space corridors (alongthe Hudson River, Wappinger Creek and Sprout Creek) to facilitate habitat protection and wildlife migration through these corridors. 6.Pursue easements for passive recreationon lands in proposed open space corridors,and/orpublic acquisition of land. 7.Study and document through maps and other means the migration of existing wildlife and the locations of all important wildlife corridors in the Town. Town of Wappinger Comprehensive Plan20 Environmental Resources B.Regulate the development of floodplains, wetlands, stream corridors, steep slopes and ridge lines to ensure minimal disruption of their environmental functions and scenic qualities. The terrain within the Town of Wappinger is distinctive and varied and includes ridge lines, hillsides with panoramic views,and numerous interconnected wetlands. These sites lend value to the semi-rural and scenic character of the Town and, if not protected or given special consideration, may lose the qualities which make them special due to poorly designed development. Ridgelines are visually prominent within the Town. Development along visually prominent ridgelines, including the removal of trees, can have significant impacts and should be limited and/or guided. Recommendations 1.Re-evaluate and considerstrengthening the Town’sWetlands Protection Law on a regular basis to ensure that it is current relative to the appropriate protection of the environment. 2.Protect significant natural features such as wetlands, streams, steep slopes and ridge lines through better management of information systems, including GIS, to enhance the evaluation during the development review and approval process. 3.Reviewzoningregulationsregarding steep slopes, and consider limiting development in areas with gradients exceeding 25 percent and regulating development in areas with slopes between 15 and 25 percent. In this intermediate steep zone, regulations should include consideration of soil types, vegetation and terrain in guiding development to minimize impacts, particularly erosion. 4.The Town should consider zoning amendmentstolimit orprevent new construction and the removal of trees along all prominent ridgelines. The Town should consider mapping all important ridgeline features to aid in the protection of these features. 5.Consider amending theTownSubdivisionRegulations to ensure that the design of new subdivisions preserve the visual and landscape quality of prominent ridgelines within the Town. Regulations should ensure that the construction of roads and the positioning of building envelopes are appropriate within visually prominent settings. 6.Consider preserving key sites on ridgelines through public land acquisition or by obtaining scenic easements. Town of Wappinger Comprehensive Plan21 Environmental Resources C.Preserve the quality and quantity of the Town’s surface and groundwater resources throughland useregulation, monitoring, testing and promotion of water-saving systems. A major component of this objective is to ensure that development in areas not expected to be served by central utilities occurs at densities low enough to protect water resources and public health.Seventy-two percent of respondents in the 2004 Town Survey supported reviewing and amending the development standards of residential districts to reflect environmental constraints.In the northeastern part of theTownthere is a mismatch between the capacity of the land to absorb waste water and the allowable density of dwelling units. Specific recommendations addressing this situation are found in the Land Use chapter. Recommendations 1.Encouragestreet and parking lot designs that minimize impervious surfaces, as outlined in the Center for Watershed Protection’s Draft Recommendations (April 2005). 2.Regulate land uses in aquifer recharge areas (along Wappinger and Sprout Creeks, near the Dutchess County Airport and in the New Hackensack area) through an Aquifer Protection Overlay District to prevent overuse and contamination of groundwater resources. 3.Establish a water quality monitoring program for the natural water bodies in the Town, particularly the Sprout Creek, Wappinger Creek, Wappinger Lake, Lake Oniad and the Hudson River. 4.Promote efficient use and re-use of water in domestic and commercial plumbing systems. The collection of roof water for domestic uses may be appropriate for properties not served by Town water. While not likely to be viable as drinking water, rainwater collection systems are feasible for irrigation, landscaping, car- washing and flushing toilets. Town of Wappinger Comprehensive Plan22 Environmental Resources D.Protect surface water quality through regulationof stormwater runoff, particularly during new construction, and throughrigorous enforcement. Recommendations 1.Considerthe need for additionaland/orhigher fees to fund enhancedenforcement efforts. 2.Develop a Town ordinance controlling stormwater, erosion and sedimentation in accordance with DEC Phase II stormwater regulations. E.Develop a system of central utilities that will protect water resources by reducing the number of failing septic systems. Ninety-eight percent of the Town’s surface consists of relatively impermeable soils. Individual septic systems built in soils with poor porosity have a high rate of failure, and failing septic systems constitute an ongoing source of point-source pollution in the Town. This objective was included in this chapter as a means of highlighting and strengthening the connection between the Environmental, Land Use, and Water and Sewer elements of this Plan.For specific recommendations regarding this issue, consult the Water and Sewer section in the Community Facilities chapterof this document. F.Protect the Town’s biodiversity through protectionof endangered species and threatened plant and animal populations,as well as through control of invasive species. Recommendations 1.Conduct a Town-wide assessment and survey of environmental resources such as properties with important natural features and areas with threatened and endangered species. Knowledge of the presence of such resources is essential in their protection. 2.Work with landscape suppliers to discourage use, stocking and sale of invasive species, and to encourage the use, stocking and sale of native species. Lists of Town of Wappinger Comprehensive Plan23 Environmental Resources discouraged invasive and encouraged native species should be incorporated into the Town’s regulations; made available on Town website; and shared, updated and promoted with landscape suppliers, professionals and homeowners as part of an educational program. 3.Consider creating a TreeProtectionLaw to protect adjoining property owners from adverse aesthetic and environmental impacts resulting from removal of trees near a property line; to prevent clear-cutting that may destabilize slopes and soils or adversely impact water resources such as wetlands and streams; to protect ridgelines; and to protectsensitive or special trees of significance. TheTree ProtectionLaw should also provide guidance and protection to the utility industry on the maintenance of trees within rights-of-ways.Currently there are no Town controls against inappropriate tree removal and clear cutting except where development is proposed on property and in cases where there are stipulated prohibitionsagainst such associated with approved development. G.Educatestakeholders, contractors, public works employees , and the public about local environmental issues and best practices. Recommendations 1.Work with local legislators and representatives to ensure that local power plants (the Danskamer and Roseton Power Plants) are in full compliance with emissions standards and requirements, particularly regarding mercury and particulate emissions. Encourage disclosure and monitoring of emissions. 2.Educate the public about the use and misuse of pesticides and fertilizers, which can have significant independent and cumulative impacts on local environmental resources. 3.Educate the public about the economic and environmental benefits of modern water softener and purification technologies through such means as an addendum to the Town water bill. 4.Explore the use of less caustic road salts and/or reduced application of road salt in sensitive areas. Town of Wappinger Comprehensive Plan24 Environmental Resources H.Cooperate with adjoining and area municipalities to address regional environmental issues, such as the Wappinger Creek Watershed Protection Commission.
