Old Business 1. Minutes from the August 16, 2018 meeting was approved - Moved by Bower, seconded by Keller, Whaley abstained. 2. Minutes from the December 20, 2018 meeting was approved– Moved by Whaley, seconded by Wenzlau, Bower abstained. New Business • Staff update on Green Stormwater Infrastructure Plan (85%) and Committee Discussion Boyle Rodriguez gave an overview of the key points of each chapter of the GSI Plan (85% draft), this plan focuses on City facilities and City right of way. Comments/ discussions during presentation: 2 August 16, 2018 - Committee members can provide comments and ask questions, where staff will gather comments and publish accordingly - Wenzlau suggests staff to explain how the public can use the GSI Plan and the purpose of the document for the public. - (Chapter4) Proximity to Existing Bikeways or Safe Routes to School Criteria: Transportation Department focuses on locations where there currently do not have an existing bikeway and potentially expand / plan for those locations, where GSI could be considered as well during planning process. Examples of GSI at bikeways could include bulb out/bioretention or pervious pavement. - (Chapter4) Keller suggested to track avoided costs and adding weighing factors to the criteria, Boyle Rodriguez explained, due to lack of data for all locations, weighing factors were not used to avoid bias. The permit requires the City to create a mechanism to prioritize projects, but are not tied to the priority results, staff and public may bring up project not listed, and justify the projects as needed. - (Chapter4) Mossar suggested to begin collecting data and investment, as in money saved if GSI is implemented. Drekmeier pointed out to also track savings from reduced irrigation costs when tree wells are used as GSI while fulfilling Urban Forestry Plan requirements. - (Chapter4) Wenzlau suggested connecting parcel size to “infiltration index” to present in maps the comparison of impervious parcels and paved parcels. Rodriguez gave example that a few city-owned surface parking lots landed on the high priority list. - (Chapter4) Boyle Rodriguez mentioned city staff should begin integrating GSI into existing CIPs planned for the near term, potentially assist in funding, and use those as demonstration sites. - (Chapter4) Wenzlau pointed out Oregon/Alma “clover leave” area could be a project location to be considered, Boyle Rodriguez explained that is not City-owned lands therefore it is not included in the prioritization listed, staff could work with the County and identify it as a partnership project. - (Chapter5) Committee discussed the chart showing the targets for acreage being treated by GSI over time. Wenzlau and Drekmeier suggested to also include the acreage of the City on the chart to provide context on how we are doing; the current impervious areas in the city which can help with setting a goal. 3 August 16, 2018 - (Chapter7) Boyle Rodriguez mentioned San Francisco has guidelines and specification that City and Private owners could follow. (Chapter8) She also stated that City departments should collaborate to address GSI features and planning in the project scoping phase, not after, and updating existing policies could encourage that collaboration. - (Chapter11) GSI Plan will be brought forth to City Council for approval on May 13, 2019 - (Chapter12) Arts/Education/Outreach: Drekmeier mentioned Juanita Salisbury is working with the City to landscape roundabout to increase pollination. Wenzlau mentioned a Land Planner from Mexico City (Palo Alto Sister City) who are interested in sharing education program on watershed through arts. - Boyle Rodriguez wished to continue solicit comments and feedback from the Committee as we move into the implementation phase of the plan. - Committee discussed the need to track and measure the efficiency, cost savings, and create proper metrics, however that requires us to first identify some baseline e.g. rainfall in PA, volume of water currently treated, impervious lands, and factoring in sea level rise as well. Bobel suggested as part of implementing the plan is that staff will begin collecting such data to identify baseline and to create meaningful metrics or performance measures. - Bower asked how would the plan incorporate future requirements, and Mossar asked about update on metrics / progress reports. Staff agreed it is feasible to provide periodic report on progress of implementation of the Plan as well as to integrating future regulatory requirements in a plan update corresponding to MRP issuance. • Committee Discussion on Topics for Draft Letter to Council Motion approved by all members to move this agenda item to one of the two future meetings in March or April. Bobel suggested staff to gather the comments from today and other written comments from individual members to create a draft comment letter on behalf of the committee, and present it at a future meeting. Adjournment: 3:00pm by Chairperson Mickelson.
