The plat proposes 60 residencial lats tota,ling approacimately 23 acres. The developrnent is divided inta eighteen (18) basins; A through R See Llrainage Niap for Midilome East Pst Addition Each basin is caenpased of two subareas? 1) grass lawr►s arid swaIes, and impervicaus raafs, driveways, and asphalt paved streets.. Stormwater flows ❑ver➢and across roofs, grass lawras, and driveways and in#o grass swales beliind the street curbs. Stormwater fram asphalt streets fiows a1ong the curb guttecs and into the grass swales thraugh driveway curb cuts and curb openings Iocated at law paints in the eurb profile. As specified in the "Guidetines fior Starmwater Mar►agement", page 5-4; where a sloping swale is 9ess than 104 feet ]ong, and slapes 1% or less, #he swale may be cansidered flat. 1]rideways along the road 'will abstruct the swales, creating a series of indiwidual svvales that are less than 100 feet long and ]ess than 1 0%, and 6 inches deep between the driveways. Therefore, each swale rraill be considered as flat. Stflrmwater will fill each swale to a b inch depth and then owerflow actmss each driveway until the water reaches the final swale and dryweU(s). The grass swales were calculated to hold the first 1I2" of rainfall runaif oVer the asphalt street areas. Figure 2, page 6-3, o£the "Guidelines far Stprrnwater Management'", by Spokane Gounty Engineers, was used for rainfall intensity and t3uration occurring at a I 0-year storm frequency. For basins H and 0, a 50-year starm frequency was used because of offsite aa-eas, , The Ratipnal and Bowstring Methods were used to calculate the peak stQrmwater runoff far each basin, and the fiYPe and number of drywells needed for each basire based ❑n che storage capacity of the swale In aecordance with °Soil Survey, Spakane County, Washingtan", 1968, the sail at the site is categorized as CrmB, Garrison Very gravelly loam, sirniiar to Garrisan gravelly loarn, except that the surface layer is very graVelly ' This type of soil is considered acCegtable far drywell installatian per Seciion 44.1 of "Guidelines far Stormwater Managernent„ _ - - - ~ - • 3 .1_v' ) l . . 5,5 $ 0_ - - - - -._-----e_~...W~_.._ .___.---•------~.~,~5 ~ -~-r.?..__---. . _ C) C? iD f-f ~ - - - p ~~~r ~ ~ . . . _ _ r~ o o_~'~-c• - - . _ - - - ~ - h -z-vQ o z ~.sEs F~~ .
