The project will replace existing septic systems with two updated systems; one will service the Gift Shop, Comfort Station, and Green House and the other will service the Main House and Veterans Museum. The new septic systems will be located on the west side of the entrance road. The sewer lines will be installed within the roadway. The asphalt pavement of the entrance drive to the Main House will be replaced in-kind with select drainage features. The parking area near the Main House and Museum will have an existing gravel area (2,912 SF) replaced with porous pavement. New septic infrastructure in the vicinity of the maintenance driveway to the Conservatory will require reconstruction of a short segment of the driveway and re-landscaping adjacent to the driveway. The driveway will be widened slightly at the bend to accommodate larger delivery trucks. Existing drainage features along this driveway will be replaced in-kind to better manage existing stormwater, along with in-kind replacement of a low retaining wall. The project also includes 5,458 LF of walkway improvements which includes the conversion of approximately 2,544 LF of existing stone dust pathways, widening of approximately 2,341 LF of existing asphalt paths from 4 to 5 feet wide, and installation of approximately 685 LF of new 5-foot wide asphalt paths. (Bid range $ 2,800,000.00 to $ 3,000,000.00).
