Pond, Vineyard East Detention Pond, and Vineyard West Detention Pond), one relocated stream reach (Saint Mary Creek), and one added stream reach (Gold Creek). WRA will conduct an additional two days of field site visits to document the revised Study Area. Visiting these sites will provide the on-the-ground information necessary to update the Biological Resources Assessment (BRA) and Wetland Delineation Reports (Tasks 1B and 1C below). Phase 1, Task 1B: Biological Resources Assessment Report WRA will update the existing draft BRA with information regarding the nine additional sites added to the Project. The funds will be used for the time required to conduct GIS figure updates and additional biological staff writing time. Phase 1, Task 1C: Wetland Delineation Report WRA will update the current Wetland Delineation draft report with information regarding the nine additional sites added to the Project. The funds will be used for the time required to conduct GIS figure updates and additional biological staff writing time. Phase 1, Task 2A: Preparation of Admin. Draft of IS/MND WRA has written, with input and review from the City, a draft Project Description for work at the sites included in the previously approved Study Area. Given the adjustments to the Study Area to include nine sites, minor revision to the current draft Project Description is anticipated to be required. Additional funds are requested to conduct the Project Description update for the purposes of the BRA, delineation, and Administrative Draft IS/MND. Phase 1, Task 28: Cultural Resources Assessment WRA has retained Basin Research Associates, Inc. (Basin) to prepare the cultural resources analysis. The cultural resources study has already conducted site assessments on the locations previously approved by City staff and will need to conduct an additional site assessment and report updates for the nine locations updated in the revised Study Area. PHASE 2, REGULATORY PERMITTING Phase 2, Task 1: Project Description and Quantification for Stream Maintenance Project WRA will work with the City to map and quantify the City's maintenance activities proposed for multiple streams and detention ponds. The current Project Description for the maintenance activities include weed abatement, silt and rock removal, and vegetation removal. The new work in this task will be used to quantify these Project activities to be conducted more specifically and discretely in order to request permits. The City will provide their work proposals (listed below), WRA will assemble the maintenance information from the City into a quantified Project Description. • Basic notification requirements about site locations; • Specific maintenance activities proposed in each location; • Type and amount of fill/ sediment removal in potentially jurisdictional areas; • Descriptions of how maintenance activities would be self-mitigating, and/or • Proposed compensatory mitigation.
