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 PROGRAM The local sediment monitoring program will build on ongoing local activities and will consist of four (4) major 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 1 & 2 (San Diego Creek between Jeffrey Road and Jamboree Road, 2) Peters Canyon Wash Reach I (Peters Canyon Wash downstream of the Santa Ana Freeway and its confluence with San Diego Creek and, 3) the In- channel basins. B. Sediment Monitoring - The County operates streamflow stations at Peters Canyon Wash at Barranca, San Diego Creek at Culver and San Diego Creek at Campus. These stations will continue to be funded by Orange 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 Work Plan - Page 2 E periodically prepares aerial photographs which include the San Diego Creek water- shed. Participants will make this information available at no cost to the program. D. Channel Erosion Study - The study involves documenting changes in the watershed, re- surveying a number of established channel cross - sections and updating the sediment budget. The study will be reduced from previous years and will be performed only in 1995 -1996 and on one additional occasion following a significant storm season. H. UPPER NEWPORT BAY - ECOLOGICAL RESERVE ELEMENT Includes those activities performed within the boundaries of the state ecological reserve. A. In -Bay unit basins - Topographic surveys of the in -bay basins will be conducted following each significant storm season which results in substantial physical alteration of the Bay. The survey will be dependent on securing the funds from the State Department of Fish and Game or other sources such as the Army Corps of Engineers. The survey results will 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. III. LOWER BAY ELEMENT A. A program to determine current velocities and directions, suspended solids (including particle size distribution), water 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 two or three major storm events each season. This element will be funded by the participants on a time and material basis. IV. ANNUAL SEDIMENT MONITORING REPORT PREPARATION A. An annual report presenting the data and findings obtained during the previous fiscal year (July 1 - June 30) will be completed by March of the following year. FUNDING AND IMPLEMENTATION Funding responsibilities for the program will be allocated as shown in the Exhibit. Cost estimates provided are based on the previous cooperative program expenditures. 0 Exhibit A 0 FUNDING ALLOCATIONS SEDIMENT MONITORING PROGRAM (1995 -2000) PROGRAM ELEMENT PARTICIPATING SHARED COSTS L UPSTREAM ELEMENT A.

The effectiveness of in- channel facilities. 2. The effectiveness of in -Bay facilities. 3. The transport of sediments to the Lower Bay /ocean. 4. The impacts of physical changes in the watershed. WORK PROGRAM The local sediment monitoring program will build on ongoing local activities and will consist of three major elements: I. UPSTREAM ELEMENT - Includes those activities performed in the watershed upstream of Jamboree Bridge. a. Scour Study - Following the conclusion of the storm season, the County Surveyor will conduct a scour study, of the lower San Diego Creek, Peters Canyon Wash and new or improved facilities in the study area, to determine the changes in channel profile stemming from erosion or sediment deposition. This annual survey will continue to be funded by the County and the results will be included in the annual report. Additional scour studies will be performed if storm conditions or sediment removal activities dictate. These additional activities will be funded by the local participants on a time and material basis. The local participants will also fund the collection of sediment samples from the scour study zone. b. Sediment Monitoring - The County operates continual streamflow stations at Barranca Parkway on Peter's Canyon Wash and at Culver Drive and Campus Drive on San Diego Creek. These stations will continue to be funded by the County and the results will be included in the annual report. During storms, samples will be taken from each station every 1 -3 hours covering both the ascending and descending phases of flow. Every attempt will be made to obtain a round of samples at peak discharge. c. Channel Erosion Study - The UCLA work involves documenting changes in the watershed and re- surveying a number of established channel cross - sections. This remains as an element of the sediment study and will be funded by the local participants. d. Participant Watershed Documentation 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 periodically prepares aerial photographs which include the San Diego Creek watershed. Participants will make this information available at no cost to the study. 0 9 Exhibit A Page 2 II. IN- RESERVE ELEMENT - This includes those activities performed within the boundaries of the state ecological reserve. a. Topographic Survey of Reserve - A topographic survey of Basin I and II will be conducted by the Department of Fish and Game following each major storm season which results in a substantial physical alteration of the Bay. In addition, sediment samples will be collected for particle size analysis by the County. III. LOWER BAY AREA ELEMENT - A program will be implemented to determine current velocities and directions, suspended solids (including particle size distributions), water temperature and electrical conductivity under storm conditions. Sediment samples will be collected and analyzed for particle size. This information will document sediment transport characteristics through the Lower Bay and will be based on the existing County monitoring program. Field measurements will be limited to two or three major storm events each season. This element will be funded by the participants on a time and material basis. ANNUAL REPORT - A report presenting the data and findings obtained during the previous July 1 to June 30 period will be completed by December 31 of each year. FUNDING AND IMPLHMENTATION Funding responsibilities of the program will be allocated as shown in Table 1. Only those costs incurred over and above ongoing activities are specified. Cost estimates provided are based on the previous cooperative program expenditures. • TABLE I FUNDING ALLOCATIONS PROGRAM ELEMENT I. Upstream Element A. Scour Study 1. Survey 2.
