Approximately 220 feet of the existing tributary will be filled by the placement of a 48-inch concrete pipe. This pipe will connect to the existing 48-inch pipe at Pacheco Blvd. At the outlet no more than 100 sf (10' x 10') of loose rock riprap will be placed to dissipate the water. A 1728 sf pond will be constructed in the area between the new outlet and the existing 60-inch pipe inlet. A rock berm will be constructed in order to pond water approximately 1 to 1.5 feet deep. Issuance of a Streambed Alteration Agreement Number R3-2000-1239 is pursuant to Fish and Game Code Section 1602.
