The road is proposed to be a Private Road, operated and maintained by the appropriate Home- owner's Association, and an easement, rather than a right-of-way, is provided on the plat. H. DRAINAGE The project is not directly affected by any major through-site drainage flows. A copy of the general drainage basin arrangement is attached as Appendix 'E'. There is a larger drainage way which crosses under Highway 34 in a 42 inch CMP north of CR 627 and flows through an open field toward CR 627. At this point the normal flow direction fades, since only a 24 inch CMP is provided under CR 627. The Spitzer High- line Ditch appears to then intercept all flows south of CR 627. Therefore, analysis of this drainage im- pact is difficult. We feel that any flows which cross the ditch would generally travel southerly and be in- tercepted by the southern end of the Private Road. We've provided 2ea - 24 inch CMP under this road to handle normal runoff as well as possible overflows from the basin above CR 627. There is also a sizable hillside north of CR 627. Drainage from this hillside does not cross CR 627 through any culvert; a field review indicates this probably overflows CR 627 near the east line of Phase 2 and thence travels southwesterly through the network of irrigation feeders. We've recommended a drainage easement along the east property line of Lot 6 to allow bypassing of such flows. Increased runoff caused by development will be negli- gible. Theoretically, the 100yr runoff from all of Phase 2 is estimated to increase from 4.69 cfs to 4.92 cfs. These total flows consist of smaller flows leav- ing the site at different locations; however, the effect of increased runoff will be minimal. Required runoff mitigation measures for this project consist of the following: 1) Reclamation and seeding of the present disposal area at the south end of Phase 2. 2) Seeding and mulching of roadside slopes and ditches. 3) Use of gravel road and driveway surfaces throughout.
