� CITY of <br />• <br />LINO LASS <br />10/24/94 <br />Standards for Facility Design <br />for a 1 -year and 10 -year design storms. Consideration as to the <br />maintenance and operation of this structure is a necessity. <br />Emergency Overflows <br />Existing, natural occurring or man -made emergency overflow <br />hydraulics from detention areas shall be calculated and be <br />analyzed as part of the design of the structure. <br />Minimum Building Elevation <br />The minimum building elevation is defined as the lowest slab <br />elevation for a home or building, including basements and crawl <br />spaces. The minimum building elevation for structures shall be the <br />greatest of the following: <br />1. An elevation 2 feet above the design storm (DS) elevation; <br />2. An elevation determined from the Freeboard Evaluation <br />Storm (FES) event (100 -year, 24 -hour rainfall, Type II, AMC <br />3 or 100 -year, 10-day runoff); or <br />An elevation based on the overflow elevation plus 1 foot if <br />the FES event controls Item 2 and the emergency or natural <br />overflow is operating and has a depth of less than 1 foot; <br />or <br />4. Four feet above the water table. <br />Pond Construction (Above Normal Water Elevation) <br />General Criteria <br />The following criteria will be followed for pond construction above <br />the normal water elevation. This area of the pond will more than <br />likely be the pond area flooded during a storm up to a 100 -year <br />duration. <br />Local Water Management Plan <br />Users Manual <br />• Maximum 3H:1V side slopes. <br />• Proper allowance for access and maintenance <br />easements. <br />SEH NO: LINOL9402.00 <br />Page 16 <br />
