The survey results syili be used to monitor the sediment deposition in the basins and assist in determining the need for maintenance cleaning activities. In addition, sediment samples will be collected for particle size analysis by the • County. I11. LONE ER BAT ELEMENT �. A program to determine current velocities and directions, suspended solids (including particle size distribution). %rater temperature and electrical conductivity under storm conditions will be conducted. Sediment samples will also be collected at selected stations and analyzed for particle size. The information will be used to document sediment transport characteristics through the Lower Bay. Field measurements will be limited to t%yo or three major storm events each season. This element will be funded by the participants on a time and material basis.

C, Exhibit A 0 WORK PLAN SEDIMENT MONITORING PROGRVNI (1995 -2000) OBJECTIVE To obtain information to evaluate: I. The effectiveness of retarding basins and channel stabilization projects. 2. The effectiveness of In- channel basins. 3, The transport of sediments to the Lower Newport Bay and ocean. 4, The impacts of physical changes in the land uses of the watershed WORK PROGRAiAI The local sedirent monitoring program will build on ongoing local activities and will consist of four (4) malor elements: I. UPSTREAM ELEMENT - Includes those activities performed in the watershed upstream of Jamboree Bridge. A. Scour Study - Following the conclusion of significant storm seasons, the County Surveyor will conduct a scour study of. 1) San Diego Creek Reach I & 2 (San Diego Creek between Jeffrey Road and Jamboree Road. 2) Peters Canyon Wash Reach I (Peters Canyon "'ash downstream of the Santa Arta Freeway and its confluence with San Die =o Creek and. 3) the In- channel basins. B Sediment Monitoring - The County operates streamflow stations at Peters Camon Nash at Barranca, San Diego Creek at Culver and San Diego Creek at Campus. These stations will continue to be funded by Oranae County EMA, and the data will be presented in the annual sediment report. During storm events greater than 0.5 inches of rain, fluvial sediment samples will be taken from each station with an attempt to cover both the ascending and descending phases of the flow and the peak discharge. At least one time during and after storm season bedload grab samples will be taken from the In- channel basins and analyzed for particle size. C Participant Watershed Document Exchange - All local participants prepare documents describing changes in the watershed and /or stream system and engage consultants to develop information on the watershed. For example, TIC I J • L� J Rork Plan - Page 2 • periodically prepares aerial photographs which include the San Diego Creek water- shed. Participants will make this information availabie at no cost to the program. D. Channel Erosion Study - The study involves docum :n:irg c angel in the watershed, re- surveying a number of established charms -I cross- sections and updating the sediment budget.
