No sinkholes, unconfined/shallow aquifers, or karst conditions were identified in the project <br />area. The geology of the project site does not result in limitations for the proposed <br />development. <br />a. Soils and Topography — Describe the soils on the site, giving NRCS (SCS) classifications <br />and descriptions, including limitations of soils. Describe topography, any special site <br />conditions relating to erosion potential, soil stability, or other soil limitations, such as <br />steep slopes or highly permeable soils. Provide estimated volume and acreage of soil <br />excavation and/or grading. Discuss impacts from project activities (distinguish <br />between construction and operational activities) related to soils and topography. <br />Identify measures during and after project construction to address soil limitations <br />including stabilization, soil corrections, or other measures. Erosion/sedimentation <br />control related to stormwater runoff should be addressed in response to Item 12.b.ii. <br />According to the Natural Resources Conservation Service (NRCS) Web Soil Survey, there are <br />five soil types within the site, which are generally loamy sands (see Table 7). <br />Table 7.

A Stormwater Pollution Prevention Plan <br />(SWPPP) will be prepared. All unpaved areas disturbed during construction will be <br />revegetated in accordance with the standard NPDES permit requirements. In areas with steep <br />slopes, special consideration will be given to prevent erosion during construction, such as <br />erosion control blankets, along with vegetation establishment to permanently stabilize side <br />slopes and any areas impacted as a result of construction. <br />12.
