Each curb irlet located at a low point is sized to accept the flow of starmwater from the caratribucing pavement subbasin. ' 2} In some cases, additional cur6 inlexs are required an cantinuaus grades. Far example, additianal curfa , inlets v,i11 intercept the stormwater on con#inuous grades along 32nd Auenue Typical runa#r Galculations have been made for the pavemenf area in subbasin A5, since this subbasin has the largest pavement area of any subbasin in the plat, it will have the largest peak flaw ❑f any subbasin A curb inlet 3.91 feet wide is required far this subhasir, but is less than the actual inlet vaidth of 4feet. SinGe, the runaff will be less in a!1 ather pavement subbasins, all other curb inlets will be suffciently wide ta intercept the stannwater in the carrespanding sub-basins. ~ 3} Driveway cuts on cant[nuous grades wi11 intercept the stQrmwaxer flaw in each pavemen# subbasin priar tv the curb irilet at the low paint. A typical calculatian has been made for a dfiveway cut for the pavement in subbasin A5, since this subbasin has the largest pavement area of any subhasin in the plat, it will ttave the 1argest peak flaw of any subbasin. A driveway cut of 10 feet is required for this subbasin, but is less than the typical driveway cut of24 feet. Since, the nunoffwiu be Pess in all ather pavement subbasins, driveway cuts for the vther subbasins will be sufficientty cvide (24 ft ) to intercept the stormwater in the carresponding subbasins. ` . , fiA'f'IONPiL..

Therefare, each of these roads will be canstructed at ICID°'o build out tor the future canditzon. The remaining raads, 34th Avenue, 35th Aueraue, 33rd Court, Vercler Court and 34t1i Cnurt, u;"s1l be cul-de-sacs or sh4r[ cross streets each with average daily traffic eounts of Iess than 200. In addition tv the Iocal access streets within the interior of the plat, 32nd Avenue will bprder this plat an ihe ncrrth. 32nd Avenue is designated as an arterial by Spokarie County. 32nd Auenue has some existina pavement, but the roadrvay r,vill need xo v,radened ta meet Spakane C❑unty standards. Based Qn the type of soi1 found at this project, the geatechrucal engineer feels that 2 inches of Class EL asphalt concrete pavement Qver ? inches of Class E asphalt cancrete pavement annd 6 inches of crushed rock surfacing will provide adequate 5ur#'acing for the vvidening of 32nd Avenue (See geatechnical report) A table af the street names, design data and the rnadway surfacinrg depths is included Midilome East 1 ~t Additiai7 sUMMARY oF r~OAawAr SuRFAcrNG DEFTHs ~s~r~~~~•~~~~ ~T,,Y~PE• 1L TYRE ~186RFACiN~;_ .
