undeveloped land. A majority of the developed portion of the site drains to the constructed north pond. This pond is located on both the subject site and on the adjacent parcel to the north and was designed to handle more than the existing development. The pond will be deepened, regraded, and updated to meet current NURP pond design standards. All new impervious runoff is being directed to this pond. Proposed peak runoff rate and volume will be less than existing. A drainage and utility easement shall be recorded over the north stormwater pond that includes both the subject site and the adjacent property. Public Utilities The existing building is served by a private well and 2 1 " municipal sanitary sewer located along Otter Lake Road. The new addition and existing building will be connected to 16" municipal watermain. Per Sheet C1-2, the existing private well will be removed and capped. Tree Preservation and Mitigation Plan The Environmental Coordinator and Environment Board reviewed the tree preservation and landscaping requirements. The following comments are from the May 4, 2022 Environmental Board staff report. The 11 trees planned for removal are in non -environmentally sensitive portions of the basic use area and will not require mitigation trees to be planted. The ash tree located southwest of the accessible parking spaces should be added to the removal list. With the addition of the tree protection fence detail, the preservation and mitigation standards will be met. Open Areas Landscape Standards Open area landscape standards require 1 large tree and 3 large shrubs per 2,000 sf. There are 7,894 square feet of open space that require 4 large trees and 12 large shrubs. Provided on site are 8 large trees and 12 medium shrubs. Four (4) additional large shrubs are required to meet open space requirements. Buffer and Screen Standards A buffer and/or screen would have been required if the portion of the parking lot west of the building were part of the new construction. As the parking lot is pre-existing, a buffer and screen will not be required. Buffers and screens requirements have been met.
