~~ Buffer to Adjacent Properties: A concern over the proposed 25' buffer to adjacent properties was noted. (~ Applicants' Response: It is proposed that this proposed design solution be modified to reflect a 50' buffer. In the event these properties are incorporated into Buckhorn Village or that they are developed in a use compatible. with that of Buckhorn Village then the buffer would cease to exist. MTC Buffer -Proposed Design Solution: A concern was noted regarding the proposed landscaping and clearing within the buffer area. Applicant's Response: The proposed clearing within the MTC buffer is needed to enable the construction of essential storrnwater quality and refiention ponds. This landscape will be defined by a natural transition from the existing pines to that of aquatic. vegetation and vegetation in keeping with the "pond side" setting. The landscaping proposed in these disturbed and inundated areas will follow the standards and guidelines listed below. . (Source: Dr. Bill Hunf, Assistant Professor and Extension Specialist, Biological and Agricultural Engineering Department, NCSU) Plantin~,s and Ve et~i ation An often overlooked item in the maintenance of a stormwater pond or wetland is the care of the trees, shrubs, grasses, and other plantings that are .growing (or trying to grow) in the impoundment area of a pond: Not only do such plantings perform a key water quality function in that they filter: out and soak up pollutants, but they also provide food a.nd cover for wildlife and add immense interest and aesthetic value to the pond landscape. The introduction (or reintroduction) of wetland anal wet meadow plantings to any pond,. even a "dry" pond,. can improve markedly the aesthetic, water quality treatment; anal wildlife habitat aspects of the facility. Many wetland plant species will perform well in water depths of up to 12". Cattails (Typha sp. ), which are natural (and, in many instances, beneficial) to a wetland environment, can sometimes choke out other, more desirable vegetation. As such, cattails. should be controlled in the earlyphases of colonization by wiping them with aquatic formulations of the systemic herbicide glyphosate. To maintain a dense, herbaceous, vegetative state in your pond or wetland (e:g., to keep if it a "suspended state of adolescence"), avoid planting large shrubs or trees that tend to shade out herbaceous species. Larger trees and shrubs should, for the most part, be reserved for those areas that surround the pond. Trees, such as river birch, red maple, sycamore, and swamp cypress will do well in a wetland area, and eastern redbud and sweet baymagnolia canprovide significant aesthetic interest in the zones surrounding a pond or wetland (e:g:, upper bank areas). When planting trees in a wetland, a tree density of no more tb:aii 3 to 4aees~ er 10 000~s uare_feet ofwetland surface area is recommended. p .. ,... q "Volunteers" should be ]im~ted, and any invasive trees, such as black willow, should be eliminated as soon as practicable. With respect to the introduction (or reintroduction) of herbaceous plants to a stormwater pond or wetland, provided below, are two lists of suggested wetland/wet meadow plants that appear to colonize well and survive in such devices. Given the complex nature of wetland plant selection and ecatyping, planting, care, and maintenance as well as how such plants respond to various permanent and intermittent pooling levels, it is recommended that all significant plant activities be conducted under the
