Soil borings must also be performed in the roadway areas to assist in designing the <br /> pavement section. <br /> Stormwater Calculations <br /> A stormwater summary report will be required. The calculations must include all disturbed <br /> areas, along with existing and proposed conditions. <br /> The LRRWMO requires volume reduction (infiltration) on all projects. The City uses the <br /> Walker spreadsheet to check for water quality treatment volume and P8 to evaluate <br /> infiltration removal efficiencies. The LRRWMO also requires rate control for the 2, 10 and <br /> 100 year storms, limiting discharge to existing rates. Water Quality treatment requirements <br /> are 90%removal of Total Suspended Solids and 60%removal of Total Phosphorus. <br /> Pipe sizing calculations for the 10-year storm must be provided with the final plat. <br /> A project manual which includes the bid form, contract and specifications must be submitted <br /> with the final plat. <br /> All floor elevations must be at least 3 feet above the highest anticipated ground water <br /> table, 2 feet above the designated or designed 100-year flood elevation or 1 foot above <br /> the nearest emergency overflow, whichever is higher. <br />
