This study analyzes the storm flows for the two tributary drainage areas in the developed condition. This study also analyzes the hydraulic capacity of the area drain pipes METHODOLOGY The 100 year Storm flows for each tributary drainage area were calculated by using the Rational method described in the Riverside County Flood Control Hydrology Manual. Hydraulic calculations were completed with the WSPG program. ASSUMPTIONS Stomr Event:, 100 year Antecedent Moisture Condition: AMC 2 Soil Type:,B SITE SUMMARY The site contains 0.78 acres net and in the developed condition drains to two concentration points via surface swales and a system of area drains. Drainage Area "A" contains 0.06 acres and drains to an inlet located in the northwest corner of the site adjacent to the drive approach. Flows from this area exit the site via a 4" cast iron pipe into Moreno Road. Drainage Area "B" contains 0.72 acres and drains to the CULTEC Recharger located near the southwest.boundary of • the site.
