City of Santee Forester Creek Improvement Project
Water Quality Monitoring

The City of Santee received a Proposition 13 Grant to help fund its Forester Creek Improvement Project.  The project included creek restoration and flood control components, including widening and revegetating the creek channel.  To assist in fulfilling grant requirements, D-MAX prepared a sampling plan, a Quality Assurance Project Plan, a 2005 Annual monitoring Report, and a Project Assessment and Evaluation Plan.  We also conducted water quality monitoring at three sites in the creek on a monthly basis for more than three and a half years.  Monitoring included specially designed trash assessments to meet Regional Water Quality Control Board (RWQCB) requirements and a total dissolved solids (TDS) component analysis to help the City gather information about potential causes of the chronically elevated TDS readings in the creek.  The final results of the program showed an almost 70 percent reduction in fecal coliform after the completion of the restoration work.
