<br />" <br /> <br />klt~rnatiYe 2 (Figure 22) ~uld interoept the sheet flow braneing west <br />of the elementary school with a curb-openinq_type slotted inlet extending 120 <br />feet east and south of the southeast corner ot the Quentine Avenue and Broad <br />Street interseotion. Flow would collect in a sump and precede diagonally <br />northwest under the intersection through three 48-inch reinforced concrete <br />cul"erte. The drain"ge ditch "'ClOt of Quantine IIvenue would be ..,diUedto <br />safely accomodate the design disc~rge south acrose the Beeline and Thompson <br />and Platte Ditches to a large existing box culvert under Highway 60 and 00 ~ <br />the L1ttle'l'no..pson River north...."st of town. <br />Alternative 3 (Figure 23) provides a 600-foot diversion channel running <br />eaet from County Road 21 immediately south of the element~ry school grounds. <br />This ditch OIOuld int..rc..pt the entire Westsrn FIQ\</Path dischll.r.,e and di rect <br />it west under Oounty ~ad 21 in four 42-inch reinforced concrete culverts to <br />the drainll.ge ditch on the.....llt $ide of the road. The drainaSe ditch would be <br />enlarged to transmit the 100-year discharge to four 42-inch reinforced <br />concrete pipell under County Road 46 3/4. From here storm ...ater would flow to <br />the Little Thompson River via the same route all described in Alternative 2. <br />Alternative 4 (Figure 24) would drain the lOO-year discharge down a <br />regraded and paved Quentine Avenue. The intersection of Quentine Avenue And <br />Broad Street .~uld be lowered to Allow flow sheeting .....st of the elementary <br />school to spill into the streets. Quentics Aven".. ...ould be lo.....red such th&t <br />the declgn disch&rge would not inundate adj4c~nt t~u..inq. A curb cut an the <br />...est side of the street at the low point on the Quentine Avenue profile <br />loc~ted north of the irrigation ditches and south of aighw4Y 60 would vent <br />drainage to the exist1ng bo>< culvert under lli9hway 60 and into the Little <br />Thompson River. <br />In all three alternatives, improvement ot drainage oondltione between the <br />existing box culvert ~d the Little Thompson River would be & helpful although <br />nonessential continuation. <br /> <br />Lola Park Tributary <br />Structural solutions to the problems encountered on the Lola F~rk <br />Tr;.butaryhave been developed indivi<lullUy for Reach A ILol" Park to the Hre <br />station pond) and Reach B (fire statlon pond to the LiU:le Tholllpson 1Uver). <br />
