C9108932 WITH LARRY WALKER ASSOCIATES TO ASSIST THE WATER QUALITY CONTROL PLANT WITH WATERSHED PLANNING ACTIVITIES RECOMMENDATION Approve and authorize the Mayor to execute the attached Amendment No. 1 to the Consultant Agreement No. C9108932 with Larry Walker Associates in the amount of $103,124 to assist the Water Quality Control Plant with watershed planning activities. DISCUSSION The Regional~ Water Quality Control Plant is a participant in the Watershed Management Initiative which conducts watershed planning in the Santa Clara Basin. In 1999, Council approved a consultant agreement in the amount of $306,000 with Larry Walker Associates to assist in watershed planning activities. Larry Walker Associates has assisted the City in working on pilot assessments and the development of a long term monitoring plan. The long term monitoring plan for the first pilot sub-watershed (San Francisquito Creek) has been prepared and an initial water quality monitoring plan has been established. The proposed contract amendment with Larry Walker Associates will provide for installation of three water quality monitoring stations on San Franci.squito Creek to implement the first pilot stage of the water quality component of the long term monitoring plan. The water quality data to be obtained by the implementation of this contract amendment will be used in conjunction with other data being collected by the Watershed Management Initiative to fulfill requirements of the Regional Water Quality Control Board and the United States Environmental Protection Agency. The most critical of these requirements is the preparation of Total Maximum Daily Loads which constitute numeric discharge limits for the Regional Water Quality Control Plant. Loadings from creeks must be estimated to determine allowable loadings for sewage treatment plants. CMR:414:00 Page 1 of 2 RESOURCE IMPACT Cost of the agreement amendment is $103,124 which will be funded from the fiscal year 2000-01 operating budget of the Regional Water Quality Control Plant. The existing agreement with Larry Walker Associates is a three-year contract with an authorized maximum of $306,000. This amendment would raise the authorized total to $409,124. POLICY IMPLICATIONS There are no policy implications associated with the approval of this agreement. ENVIRONMENTAL ASSESSMENT This work does not constitute a project under the California Environmental Quality Act and therefore an environmental assessment is not required.
