The field delineation determined there to be one perennial stream along the southern property boundary. This unnamed tributary to Mine Creek is depicted on the Wake County Soil Survey and is therefore subject to the Neuse Buffer Rules. The entire existing school and site improvements will be removed and a new elementary school facility, parking and other site improvements will be constructed. The rebuild of the school will improve many safety and functionality features that could not be retrofitted within the current school facility. The school site will require the disturbance of approximately 1 1.8 acres and result in an increase of impervious areas from 3.62 acres to 5.63 acres. A wet detention basin is planned to meet stormwater requirements for the site. The stormwater plan is being reviewed by the City of Raleigh. Due to space limitations, the out fall from the detention basin will not be able to achieve diffuse flow before entering the buffer. The detention basin will be performing nitrogen and TSS removal as well as attenuating peak discharge before discharging to the onsite stream. Outfall protection will also be provided. The riparian buffer will be impacted due to construction and continued maintenance of the outfall and associated pipe. A 20' width corridor will be permanently maintained and is considered a permanent buffer impact. A 4' construction access to the west of the permanent corridor will be replanted and is considered a temporary buffer impact. The area within the sanitary sewer easement is considered a temporary impact as well since it is already under a vegetation maintenance plan with the City of Raleigh. Please see the attached buffer authorization form and accompanying materials for additional details.
