From an engineering standpoint, the most efficient and direct method of providing access to the site continues to be via Bolin Creek However, the following alternatives have been identified and explored in a preliminary way. 1. Bohn Creek Parallel, Existing Terminus to Greene Tract Boundary This option wouldextend the existing sewer line from its current terminus on Bohn Creek northeast of the Homestead Road/Rogers Road intersection. However, rather than placing the line along the creek, this option would offset the line extension to the northwest of Bolin Creek and parallel the creek to the Greene Tract boundary. The extension of sewer could then move north of the Bolin Creek corridor as it crosses the Greene Tract boundary, avoiding the sensitive bottomland hardwoods along the creek on the Greene Tract The sewer line could be routed in a manner to minimize disturbance along the creek and reduce the amount of clearing necessary. While OWASA requires a 30-foot wide easement for its sewer mains, it would be possible to limit the cleared portion to only 20 feet minor adjustments to the alignment could also be made to avoid larger specimen trees and retain the buffer along the creek to the greatest extent possible. This option would avoid more expensive pumping of sewer by using gravity lines, and would be able to serve almost all of the proposed affordable housing area (on
