#913 Paul Phillips Page 2 June 21, 1985 The County Highway Department has approved the access location for the future private road. The Comprehensive Plan has classified County Road 6 as a minor arterial road with an 80' right of way width. The City must deny the County's request for an additional 10' of right of way providing for a total 100' right of way. Septic All lots have suitable areas for both principal and alternate on site septic systems. Staff recommends berming, ditching or another approved technique to prevent drainage f rom f uture road being directed to mound areas on Lot 1. Future road construction and drainage from the road if not properly designed will create major problems for the septic system. Staff strongly suggests the berming at the time the septic system is constructed because the existence of the berm during road construction will serve to protect or flay the septic area. If ditching or another means is to be provided at the time of future road construction, the septic area could easily be destroyed by a contractor unfamiliar with the si*uation. The important thing for the developer to realize is that there may not be another suitable septic area on this lot if the tested area is destroyed. Drainage Concerns There are no designated wetlands within the area of the plat. Staff's concerns center within Lot 1. Review Exhibit F. The shared lot line between Lots 1 and 2 has been adjusted to provide Lot 1 more high dry ground within the building envelope. The flat topography, high water table, and soils makeup place restraints on the building envelope. Lot 1 contains a drainage tile that carries runoff to the northeast underground via Lot 3. This tile line must be 1(-gated and designated as a drainage easement on the final plat. The ir'--t of the tile is at the 1005.5 elevation, the first habitable floor " the residence structure must be two feet above the elevation at l .: i.5' . Before final plat i pproval, the City Engineer should determine if there � s a need to also ask for drainage easements around the area of the inlet within Lit 1. Please note Lot 1 already has 2.65 acres in area. The applicant's engineer has also confirmed that drainage from road flows to south side of Highway 12 and does not stav within Lot I. There is a natural berm or hump in the topography that prevents it from flowing over Lot. I to drainage tile.
