REVIEWED BY: Elizabeth Drayer, PE, RCE #46872

SUBJECT: Data Collection and Data Gap Analysis

The Russian River Watershed Association (RRWA) has prepared this annotated list of information and data collected and reviewed in support of the Russian River Storm Water Resource Plan (SWRP). A substantial volume of information is available for the Russian River watershed from a variety of sources. This information comes in the form of reports, plans, permits and geographical information system (GIS) data.

DATA COLLECTED

The status of information and data collected and reviewed is summarized in three tables below. The reviewed information and data (Tables 1 and 2) are tabulated and further organized by which SWRP element is addressed. Table 3 summarizes known information and data still needing to be collected and the expected source of the data.

The Russian River Watershed Association complies with ADA requirements and will attempt to reasonably accommodate individuals with disabilities upon request.

Please contact Andy Rodgers, Executive Director, at 707-508-3670 with any questions. Russian River Watershed Association Memorandum, June 9, 2017 Page 2

ADDITIONAL DATA NEEDS

Additional information and data may be needed and encountered as work on the SWRP progresses, and once the watershed and watershed priorities are better understood and defined. As projects are proposed and prioritized, additional information and data to support the projects may be needed during the SWRP preparation progress.
