Secondary and Cumulative Impacts Master Management Plan - 2014

SECTION 5 – SCI RELATED TO PROJECTED GROWTH IN PLANNING AREA

Wetland functions also may be decreased if pollutant impacts occur. For example, sediment loading from stormwater runoff may affect hydrology and vegetation within a wetland. Nutrient enrichment and other surface water pollutants may affect amphibians and aquatic organisms inhabiting a wetland. In the long term, overall quality and total acreage of wetlands may be decreased by SCI in upland portions of the Planning Area. However, these impacts will be minimized by stream buffers, floodplain protection, and other development controls. 5.5 Prime or Unique Agricultural Land As land is developed, prime farmland soils will be disturbed. However, recent growth has already converted many acres of agriculture and prime farmland soils within the Planning Area to other land uses, and no active agriculture lands are present in the Planning Area. This conversion and disturbance of soils would likely continue, even without the proposed infrastructure, because of the proximity to RTP and other development in the area, while the pattern of growth may be different than predicted and the density may be lower, prime farmland soils would still likely be converted and/or disturbed. 5.6 Public Lands and Scenic, Recreational, and State Natural Areas Growth in the Planning Area should have limited impacts on scenic and recreational areas that are currently part of the park systems. These areas may become more valued by the community as forested areas are converted to other land uses. The Town recognizes the value of these spaces and has a plan of action to protect natural resources and open space, documented in the UDO and Parks and Recreation Master Plan. These plans are further discussed in Section 6. With the continued implementation of the Town’s plans, scenic areas, open space, and parks will be a high priority for the Town and will provide mitigation for losses of open space as the Town grows. 5.7 Areas of Archaeological or Historical Value Historical areas may be impacted directly by future projects, but indirect impacts are unlikely. Direct impacts to historic resources will be assessed individually during project planning processes. Assessing historical properties is beyond the scope of this document, because this document focuses on SCI. Some loss of historic resources could inadvertently occur with development. For example, an unknown cemetery could be destroyed. Where historic resources are known, they should be protected over time. The Town has three properties on the NRHP: the Morrisville Christian Church, the Williamson Page house, and the James M. Pugh House. Some structural damage could occur to historical structures, if they exist near future developments, as a result of vibrations from increased traffic or acid rain that may occur from increased emissions to the atmosphere. The Town has proactively relocated the James M. Pugh House, as well as two historic tobacco barns to prevent potential impact. The Town’s Historic Crossroads Village zoning district as well a the Town Center Plan encourage preservation of historic resources. It is likely that few SCI will occur to cultural and historical resources.
