9.C. - Page 5 of 30 addition when these facilities are already required. For projects currently under review, staff has been using the "no missed opportunities" section of the existing MRP as the authority to require these improvements, and have been working with developers to install the GI improvements in practical locations. Nearly every project since mid -2018 includes facilities that treat the project's frontage drainage area. With the creation of the GI Plan, staff intends to include this practice as policy but still provide staff the discretion to determine the appropriate locations for these facilities so as not be impactful to other interests in the right-of-way. Based on projects that recently have been approved or currently are under review, staff expects approximately 14 acres of GI to be installed. Reauirine Stormwater Treatment on an Increased Number of Building Remodels In doing the analysis, staff considered whether MRP goals could be met by requiring stormwater treatment on partial commercial remodeling projects. In this scenario, it was envisioned that the developer would provide treatment as a percentage of the building area being remodeled. In practice, it would mean that if 20% of the building is being remodeled, then 20% of the land would need to have capture and treatment facilities. For sites where the building covers the entire parcel, the City would be more flexible about allowing mechanical treatment devices or other GI in the right-of-way to ensure compliance. Another consideration is a change to the meaning of "substantial commercial remodel" to state that if 50% or more of the building were remodeled within a period of three years, the site would need to meet all local development standards including all applicable requirements of the adopted GI Plan. One or both of these changes would greatly increase the number of sites that install capture and treatment facilities. Policies involving remodeled buildings would be more impactful than the land - threshold and right-of-way related policies. Staff would like direction as to whether a change to the "substantial commercial remodel" definition should be considered for inclusion in the GI Plan. Next Steps With the City Council's direction for these policy changes, staff will be able to create the GI Plan which will adequately identify how the City intends to meet the goals of the MRP. Staff expects that even if all of the above changes are made to the City's development standards, the regional project at Red Morton Park would still need to be constructed to fill the gap for meeting the MRP goals. Because it is inherently uncertain how much development there will actually be prior to 2040, it is not clear how much of a gap there will be. The benefit of the regional project is that it acknowledges the Town of Woodside and San Mateo County's stormwater contribution to Redwood City's watershed, and it would ease the City's financial obligations if those agencies could be potential partners in sharing the cost of improvements and ongoing maintenance of the project. San Mateo County in particular has shown great interest in the project, and has been helping Redwood City in applying for grant funding to get the project both designed and constructed. The County recently received notification of a successful grant application from the Environmental Protection Agency for the conceptual design of the Red Morton Regional Project. Staff anticipate seeking direction from the City Council on forming a partnership with the County and the Town of Woodside to pursue the project after the conceptual design is complete.
