softened the subgrade to the degree that the pavement structure is weakened and completely broken up, see Figure 9. There is no mention of this unacceptable drainage situation in the DEIR, but it must be corrected if the Hidden Canyon Residences and Preserve project is approved. It has a direct bearing on the Vinson/EBRPD and Parking/staging area driveways and the parking/staging area lot. Also, it is entirely conceivable that problems similar to this may occur for the proposed project. The proposed project will divert a significant amount of water from Devaney Creek. It is stated in the report “the proposed projects bio retention areas would have sufficient stormwater capacity to serve the proposed project, preventing surface runoff”. If this is the case, then in a normal year 10 acre-feet (or more) of runoff would not flow into Devaney Creek. (Based on the proposed project increasing the impervious surface area by approximately 7.4 acres and an average annual rainfall of 18 in,) The State Water Resources Control Board regulates the diversion of water from “blue line” drainages in California. Devaney Creek is a “blue line” drainage. Have the developers contacted the State Water Resources Control Board regarding the diversion of water they have proposed? I have a 75+ year-old 2-acre lake/“stock pond“ on my property at the head of Devaney Canyon. I divert a similar amount of runoff from Devaney Creek. I am regulated by the State T.
