Hydrology calculation was done based on River Side County Hydrology Manual. Pre developed and Post developed hydrology calculation is included in this report. Basically the drainage pattern is so that 7 lots drain to Deodar Lane and from there to the proposed culvert on Green Tree road and 3 lots drain to Rancho Vista road. Also rip rap calculations are included in this report. All the hydrology maps and calculations are attached to this report for city review.
