Financial assistance may be available for repairing damages and mitigation actions to prevent future damage. Funds are available both from the State Office of Emergency Services (OES), and the Federal Emergency Management Agency (FEMA), which can be combined to provide the maximum assistance to individuals, businesses or agencies. Press Releases providing the toll free number to register for assistance 1-(800) 462-9029, have been published in the newspaper a number of times, and those calling have been advised. Registration must be filed by March 26, 1992. One program, through the U.S. Department of Agriculture/Soil Conservation Service, provides funding for natural streams and slopes on private property, which impact the -general public. The Wiley Canyon Creek in the vicinity of Mulberry Mobile Home Park, and the Wiley Canyon Slope in the vicinity of "S Curve", are two areas within the guidelines of this potential funding source. Wiley Canyon Creek Damage sustained by the Mulberry Mobile Home Park was a result of a number of factors. Some of those factors, but not limited to, are as follows: 1. Debris and dead vegetation in the natural stream area; 2. The shallowness of the channel because of silt adjacent to the I-5 freeway. Removal of the debris and dead vegetation,. and dredging of a portion of the stream has been discussed with the Corps of Engineers, U.S. Fish and Wildlife and State Fish and Game, who have all given tentative acceptance of the mentioned corrective actions. APPROVED igen {tem:m5- Wiley Canyon Slope/Creek - Storm Damage Mitigation Relief Page 2 Meetings have also been held with the U.S. Soil Conservation Service, CalTrans and the California Conservation Corps for 1) funding availability through the Soil Conservation Service program under Emergency Watershed Protection, 2) CalTrans acceptance of work, within the drainage easement adjacent to the freeway, and 3) the California Conservation Corps for performance- of the debris removal and vegetation removal. Discussions have also been held with representatives from the Smiser Property and Taylor Property who have given tentative consent for work to be performed on their property as described. Wilev Canvon Slone The slope on the east side of Wiley Canyon at the "S Curve" has been identified or as potentially unstable during a heavy rainstorm. The conditions required frequent closure of Wiley Canyon and continued sandbagging to prevent damage to adjacent homes and also requires extensive roadway cleanup. The U.S. Soil Conservation Service has been requested to consider work to stabilize this hillside for funding under the Emergency Watershed Protection provision. This location is still under review. City Responsibility/Liability In both projects the basis for federal funds being available is that the public is impacted because of work required on private property. A public agency, in this case, the City of Santa Clarita, therefore, must sponsor the program. The normal sponsorship is usually 80% federal emergency funding, and 20Z the sponsoring agency, which can be reimbursed in whatever form the local agency may be successful in accomplishing. One of the other conditions is that the local agency assume the responsibility for the maintenance of the area to assure that the work performed does not deteriorate and that the condition causing damage does not reoccur. The representatives from both the Taylor and the Smiser Property have indicated a tentative acceptance of a mechanism, such as a Storm Maintenance District, whereby the continued maintenance of the creek would be their financial responsibility. The magnitude of maintenance for the slope stability has not yet been determined. The City should seek a similar acceptance of responsibility by that property owner. The City Attorney has indicated that sponsorship of work does not admit acceptance of responsibility by the City for damage sustained from the February 10-18, 1992 storm. In order to be within the guidelines of performance of work under the imminent danger guidelines and 10OZ funding, it was essential to send a request to the U.S. Department of Agriculture/ Soil Conservation Service requesting funding, intended sponsorship, and proceed with acquisition of all necessary approvals Wiley Canyon Slope/Creek - Storm Damage Mitigation Relief Page 3 for the work as quickly as possible. Attached is a copy of the letter submitted to the Soil Conservation Service and it is now appropriate for the City Council, to confirm this action and to provide any guidelines to staff in the processing of this request. It should be noted that at any time should any of the necessary agreements either with the Soil Conservation Service, California Conservation Corp or the property owners not be in the City's best interest, the City may withdraw its request and sponsorship. The California Conservation Corps (CCC) will accept the removal of the debris, dead vegetation and trimming of live vegetation consistent with the U.S. State Fish & Came, and the U.S. Army Corps of Engineers -as a project. The estimated cost of work is $20,000 - $30,000 which would be federally reimbursable. A separate contract with,a private contractor for major removals and. dredging, which could cost $40.000 - $60,000. The total project for the stream work could be $188,000.A contract with both the CCC and the U.S. Department of Agriculture/Soil Conservation Service is required to proceed with the work. Should the work not be fully reimbursable this matter will be brought back to the City Council for reconsideration. Council will be advised of the Wiley Canyon Slope stabilization and storm flow control as an acceptable federally funded project. Recommendation 1. Concur with the City Manager's request to the U.S. Department of Agriculture/Soil Conservation Service for funding necessary to work on the Wiley Canyon Creek. 2. Authorize the Mayor to execute.the agreements with the U.S. Department of Agriculture/Soil Conservation Service. and the California Conservation Corps, subject to the City Attorney's approval. 3. Direct staff to prepare necessary plans and specifications. 4. Proceed with establishment of the maintenance mechanism with the property owners as required by the funding program.
