Eklibit B <br />22. a.1 Surface and <br />Storm Water Runoff <br />The project site is <br />located within the Grass Lake and Central Ramsey <br />watersheds.. Drainage <br />from the north half of the site is collected in a <br />swale along County Road <br />B-2 and flows west to a storm sewer inlet at the <br />intersection of County <br />Road B-2 and Dale Street. Fran this inlet water <br />flows south in a 15" <br />diameter pipe to the intersection of Dale Street and <br />Lavell, and from this point the storm sewer flows west and north and <br />eventually outlets to <br />Lake Owasso. <br />The south half of the <br />site drains overland to a storm sewer inlet located at <br />the southeast corner <br />of the site. Water collected at this inlet enters a <br />24" diameter pipe and <br />is discharged approximately 100' south to the Highway <br />36 ditch drainage system <br />and eventually outlets to McCarron Lake. <br />The proposed site grading and storm sewer plan provides for a network of <br />catch basins to collect storm water runoff from within the site. These <br />catch basins will be <br />connected to the 24" diameter storm sewer located at <br />the southeast corner <br />of the site. All of the site except for small areas <br />around the perimeter <br />of the site will drain to the on -site storm sewer <br />
