This study area is illustrated within Plate 7 at the rear of this report. Prior to construction within the 15709 -3 and 15709 tracts, protective measures against flooding of dwellings within these two tracts from runoff coming off the study area must be proven. Two facilities are investigated within this report. The first is an earthen channel which will be graded along with the balance of the project during rough grading operations. The second is a smaller earthen channel which will be constructed concurrent with the Walnut Avenue improvements. The first earthen channel will be 4 feet deep typically and will reduce in depth to 3 feet within 200 feet of Cherry Avenue. The entire channel and daylight slopes will be within the right of way dedicated by the 15709 -3 and 15709 final tract maps. This channel will carry the 100 year flow of 193 cfs and maintain a minimum freeboard of 12 inches. The velocities can be controlled by the implementation of sandbag check dams placed along the stretch of channel. At the westerly and downstream end, the channel will not have a daylight outlet. It is proposed to install a sandbag checkdam along the rim of the downstream end. Low flows will pond and infiltrate easily as proven in recent infiltration tests done for the Sierra Lakes Project. Heavier flows will raise to an elevation and discharge through P.V.C. pipe outlets or weirs created by omitting bags within the vertical rows. Details of this checkdam can be seen on the rough grading plans for Tract No. 15709 -3 and 15709. The latter facility will be an earthen channel 15 inches deep, with a base width of 5 feet. This channel will be constructed adjacent to a 15 feet wide graded shoulder north of the paved improvements of Walnut Avenue. This channel will carry the 10 year flow of 89.80 cfs. The 10 year flow will collect into (2) 22 "x36" arch C.M.P. pipes and cross Cherry Avenue and discharge into a proposed swale along the w shoulder. The 100 year runoff will flow within both the swale and proposed street improvements. c SAN GABRIEL MOUNTAINS It -1#46). Lu , SUMMIT AVENUE . cc W STllDY I W z 4.k cn 41 � •1.'
