HomeMy WebLinkAboutSWA000194_Construction Sequence_20230316Gretchen Pines Phase 4 Construction Sequence Phase 4 is a continuation of the Gretchen Pines single family subdivision. It starts at the end of the road constructed in Phase 3. Since this is at a high point, no drainage from Phase 3 will flow into Phase 4. Phase 4 will include 59 homes on lots ranging from just under a half -acre to almost two acres and include over thirty acres of open space. The subdivision will be served by a two-lane ribbon pavement road (no curb and gutter) with drainage swales (max of 3:1 side slopes). Drainage will then be conveyed by 10 swales (3:1 side slope max) from the road to the project perimeter to keep flow as dispersed as possible. A planned Phase 5 will start at the end of Pewter Drive in Phase 4. A 300' section of Pewter Drive will drain to the future Phase 5 and include 5 houses. This drainage will be handled in Phase 5 by continuing the swale system as done in Phase 4 and previous phases. Phase 5 is planned to be the last phase of this subdivision. AL 027502 1 F/'G 1 NSS�' N
