Stakeholder Outreach Plan

Santa Clara Basin Stormwater Resource Plan Stakeholder Outreach, Education, and Engagement Plan March 27, 2017 Introduction The Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP or Program) is developing a Storm Water Resource Plan for the Santa Clara Basin (SWRP). The development of the SWRP is being funded by a Prop 1 grant from the State Water Resources Control Board to the Santa Clara Valley Water District (District). SCVURPPP is an association of thirteen cities and towns in Santa Clara Valley, the County of Santa Clara, and the Santa Clara Valley Water District that share a common NPDES Municipal Regional Permit (MRP) to discharge stormwater to South San Francisco Bay. The SWRP will identify and prioritize multi-benefit runoff capture projects throughout the Basin, using a metrics-based approach for quantifying project benefits. The metrics-based analysis will be conducted using hydrologic/hydraulic and water quality models coupled with GIS resources and other tools. The products of these analyses will: 1) be a map of opportunity areas for runoff capture and use throughout the basin on a watershed basis; 2) an initial prioritized list of potential projects; and 3) strategies for implementation of these and future projects. These projects are intended to improve water quality, reduce localized flooding, and increase water supplies for beneficial uses and the environment. The SWRP will be coordinated with the Santa Clara Valley Water District’s current efforts to develop its Integrated Water Resources Master Plan (“One Water” Plan). The One Water Plan is an Integrated Water Resources Master Plan to identify, prioritize and implement activities at a watershed scale to meet flood protection, water supply, water quality and environmental stewardship goals and objectives. In addition, the SWRP will be coordinated with storm drain master planning efforts being conducted by SCVURPPP member agencies, and their efforts to develop local Green Infrastructure Plans by 2019 as required by the MRP. In April 2016, SCVURPPP developed a Green Infrastructure Education and Outreach Strategy (GI Outreach Strategy) that identifies audiences, messages, goals, and specific tasks needed to accomplish the GI outreach requirements in the MRP. Implementation of the GI Outreach Strategy requires the development of several outreach materials on green infrastructure. The materials developed will be used to support implementation of the SWRP Stakeholder Outreach, Education, and Engagement Plan. The SWRP Stakeholder Outreach, Education, and Engagement Plan identifies the goals of stakeholder involvement and describes the tasks that will be implemented to conduct outreach to stakeholders.

Goals of Stakeholder Outreach, Education, and Engagement Active stakeholder involvement during the development and implementation of the SWRP and associated runoff capture and use projects will help ensure the desired environmental outcomes. Stakeholder outreach for SWRP will be conducted to meet the following three goals: 1. Inform stakeholders on the SWRP process and the need for developing multi-benefit green infrastructure projects. 2. Obtain stakeholder input in identifying locations and types of multi-benefit green infrastructure projects, and project concepts. 3. Obtain feedback on the initial prioritized list of potential projects.

Key Messages The following key messages will be conveyed to stakeholders:  Using stormwater as a resource.  Need for multi-benefit green infrastructure projects.  Local agency requirements and efforts to develop green infrastructure projects, with examples.  What is the SWRP and why is it needed?  Process for identifying, assessing, and prioritizing green infrastructure projects.

Stakeholder Outreach, Education, and Engagement Tasks The following tasks will be implemented to meet the goals of stakeholder outreach: Task 1 – Stakeholder Group Formation The SWRP stakeholder outreach effort will build upon the process currently underway through the District’s One Water Plan project. The District has convened a Stakeholder Working Group (SWG) of diverse representatives from the following sectors: academic, agriculture, business, civic/public policy (including environmental justice), environmental, housing/neighborhoods (including Disadvantaged Communities and Economically Distressed Areas), conservation agencies, local and state government, tribal government, recreation, transportation, and water supply/quality. For the SWRP process, stakeholders will be solicited from the District’s SWG (Attachment A), and from other local organizations that are interested in stormwater issues. Local organizations that provided letters in support of SCVURPPP’s Prop 1 Grant application will also be invited to participate on the Stakeholder Group. A list of additional potential stakeholders, including suggestions from the SWRP Technical Advisory Committee, is included in Attachment B. Schedule: Potential stakeholders will be contacted in March and April, 2017. The Stakeholder Group will be established in May 2017. Task 2 – Quarterly Updates Beginning June 2017, quarterly updates will be sent via e-mail to the Stakeholder Group to update them on the progress toward the SWRP. Informational materials (e.g., flyers, fact sheets) will be developed and distributed to stakeholders as part of the quarterly update. Schedule: Quarterly, beginning June 2017. Task 3 – Stakeholder Group Meetings As described below, the District and SCVURPPP plan to hold up to three Stakeholder Group meetings to share information and solicit input on the SWRP:  Overview Meeting – The first meeting of the Stakeholder Group will introduce stakeholders to the SWRP development process and the initial work completed.  Project Prioritization Meeting – The second meeting of the Stakeholder Group will inform stakeholders on the process for identifying, assessing, and prioritizing green infrastructure projects, and solicit input on the process and potential projects.

Depending on the attendance and extent of participation at the first two meetings, a third meeting may be held at the Peninsula Watershed Forum during the project prioritization process to get additional feedback. The Peninsula Watershed Forum is a meeting of local citizens, agencies, and organizations working on watershed-related issues for the purpose of networking and sharing information. SCVURPPP staff previously attended a meeting of the Peninsula Watershed Forum in December 2016 and presented information about green infrastructure requirements, design, and case studies, and background on the SWRP and District’s One Water Plan. In addition to these meetings, District staff will continue to include information on the SWRP in their outreach to One Water Plan stakeholders. Meeting handouts and presentations will be provided to SCVURPPP member agency staff for conducting local outreach meetings. Schedule:

 Overview meeting – July/August 2017.  Project Prioritization meeting – December 2017/January 2018.

Task 4 – Website Development and Maintenance A website (or webpage on the SCVURPPP/Watershed Watch website) will be developed to post information related to the SWRP. The website will be updated regularly, and will be a tool for keeping the stakeholder group and the general public updated on the SWRP. The website will also be used to post the draft SWRP for review by stakeholders and the general public, and provide a place to post comments on the document. The website will be linked to the District’s One Water website. Schedule: The website will be launched in August/September 2017.

Task 5 – Public Workshop One public workshop will be held to obtain feedback from the general public on the SWRP. The workshop may be held in more than one location in the County to increase participation. Workshop materials will be provided to SCVURPPP member agencies for conducting additional public workshops or project-specific outreach workshops. Schedule: August 2018.

Task 6 – Development of a Community Partnership Strategy for SWRP Implementation The stakeholder engagement process will be used to guide the development of a Community Partnership Strategy for SWRP implementation. The Community Partnership Strategy will include guidance and resources for engaging local affected communities in project design and implementation. The Strategy will be incorporated into the SWRP document. Schedule: August 2017 - May 2018.

MEETING SUMMARY

Participants – Attendance list attached. 1. Welcome/Introductions Brian Mendenhall (SCVWD) welcomed stakeholders to the meeting, and provided a brief background on the Santa Clara Basin Stormwater Resource Plan (SWRP). Attendees introduced themselves.

2. Overview of SWRP Jill Bicknell (SCVURPPP) updated stakeholders on the following: purpose of SWRP, green infrastructure (GI) projects, Municipal Regional Permit requirements for local GI Plans, project area watersheds, and the water quality and water quantity issues that will be considered during SWRP development. Attendees provided the following feedback:  Ensure that the SWRP describes how GI projects will be maintained. Jill clarified that the SWRP will include a chapter on maintenance. Further, each agency’s GI Plan will identify maintenance plan and local funding options. Typically, public works or parks staff are responsible for the maintenance of GI features.  Ensure that the list of prioritized projects is maintained and updated. Jill responded that the SWRP will be a living document. It will include guidance on the frequency and process for updating the project list.  Include a mix of projects in the SWRP, rather than just a few regional projects. Consider having separate priority lists for regional and smaller projects. 3. Proposed Methodology and Metrics for Identifying, Evaluating and Prioritizing GI Projects Steve Carter (Paradigm) gave a presentation on the proposed methodology and metrics for identifying, evaluating and prioritizing GI projects. Attendees provided the following feedback:  The screening criteria for slope is too low. Consider including project sites with steeper slopes.  Consider providing more points for the following: o Projects at schools/golf courses o Projects at parking lots, as compared to those at parks/open spaces.

1 o Projects that contribute to community enhancement. o Projects that contribute toward biological/ecological benefits. o Projects that benefit disadvantaged communities.  Co-location credits should not take precedence over multi-benefits. Either increase the scores assigned for multi-benefit projects, or assign a negative score for projects that do not provide multiple benefits.  When the SWRP is updated, consider providing an opportunity to revise prioritization criteria based on project performance. A memo describing the proposed methodology will be sent to the stakeholders for review and comments. Stakeholders are encouraged to submit written comments.

4. Process for Submitting Potential Projects Jill informed attendees that a spreadsheet will sent to them for collecting information on potential projects.

Action Items:  SCVURPPP staff will send today’s presentation, the memo describing the methodology for prioritizing projects, and a spreadsheet for submitting potential projects to stakeholders.  Stakeholders will submit comments and potential projects within two weeks of receiving the memo and spreadsheet.

MEETING SUMMARY

Participants – Attendance list attached. 1. Welcome/Introductions Kirsten Struve (SCVWD) welcomed stakeholders to the meeting. Attendees introduced themselves.

2. SWRP Status Jill Bicknell (SCVURPPP) updated stakeholders on the following: purpose of the SWRP, approach to identifying and prioritizing projects, and the SWRP development schedule (see slides 1-10 in the attached presentation). A memorandum describing the proposed methodology and metrics for identifying, evaluating and prioritizing Green Stormwater Infrastructure (GSI) projects was sent to stakeholders after the first stakeholder meeting. The project team used the methodology to identify and screen projects, apply benefits scoring metrics, and develop a list of prioritized projects. The project team will next conduct hydrologic modeling to quantify benefits and prepare conceptual designs for 5-10 projects, and develop the Administrative Draft SWRP.

3. Development of Methodology and Metrics for Identifying, Evaluating and Prioritizing GSI Projects Steve Carter (Paradigm) gave a presentation on the initial project screening, and explained the criteria used to score projects. He explained that identified projects were classified as LID (parcel- based project), regional (LID >0.25 acres), and green streets. Based on SCVURPPP agency input, a weighting factor of two was added to each of the following metrics:

 Percent impervious area draining to the project  Location near PCB interest areas  Augments water supply (based on location near groundwater recharge area and away from groundwater contamination areas) The prioritization process identified 2,558 LID project opportunities (including 1,983 regional project opportunities), and 52,583 green street opportunities. All of the regional and LID projects will be included in the SWRP. The top 10% of green streets for each SCVURPPP agency will be included in the SWRP. All stakeholder submitted projects will also be included in the SWRP (see slides 11-25 in the attached presentation).

1

Steve and Jill provided the following clarifications based on questions from attendees:  The project criteria “located within flood prone catchment” includes projects located upstream of the flood prone areas.  The criteria “Contains PCB Interest Areas”, does not mean that PCBs are present; it means that the drainage area to these projects may have PCBs based on historic land use. LID/GSI treatment measures are effective in removing PCBs, based on monitoring studies.  The SWRP will not go into too much detail about Co-permittee PCB load reduction and source control efforts. However, it will explain this metric further and include a map showing old industrial areas where PCBs in soils are more likely to be detected at higher concentrations. Individual Co-permittee GSI Plans will have additional information on locating GSI projects in these areas.  Projects in cities located in the hills did not receive additional credit for higher rainfall or steep slopes.  The SWRP roughly categorizes projects as high (>90th percentile), medium (60th – 90th percentile), and low (<65th percentile) priority. However, it is expected that Co-permittees will overlay their own local priorities as part of developing GSI plans.  Projects will not be identified as urgent priority by the SWRP, it will be up to individual agencies to prioritize.  Co-permittees will have another chance to review the prioritized project list before it is submitted with the SWRP.

4. Projects Selected for Quantification of Benefits and Possible Conceptual Design The SWRP project team worked with Co-permittee agencies to identify a set of projects for conducting hydrologic modeling to quantify project benefits (stormwater volumes captured and pollutant loads reduced). Information on approximately 6 green street and 17 LID/regional project opportunities was collected. In parallel with the modeling effort, the project team will conduct field visits to selected project sites, determine the final list of projects for conceptual design, and prepare conceptual designs. Steve provided examples of the initial drainage areas and footprints for potential project concepts, and the conceptual project designs developed as part of the San Mateo SWRP (see slides 26-36 in the attached presentation). He clarified that the conceptual project designs will include preliminary cost estimates. Keith Lichten (Water Board) informed stakeholders that the second round of Prop 1 Stormwater Implementation Grants will be announced in late 2018, or early 2019. Water Board staff will work with local agencies to align projects with grant requirements. Luisa Valiela (EPA) said that the San Francisco Bay Water Quality Improvement Fund grant will be announced in September 2018. It will include funding for GSI projects.

WORKSHOP ANNOUNCEMENT

Stormwater Resource and Green Stormwater Infrastructure Planning: Opportunities for Multi-Benefit Projects in Santa Clara Valley Workshop for Builders, Developers, and Engineering Consultants

Thursday, November 29, 2018 9:00 am – 12:00 pm

Community Hall Cupertino City Hall 10350 Torre Ave, Cupertino, CA

To reduce the impact of urban development on waterways, local municipalities are developing Green Stormwater Infrastructure (GSI) Plans for incorporating Low Impact Development (LID) designs into new and existing drainage infrastructure on public properties and rights-of-way, including streets, parking lots, and parks. These GSI Plans will guide how and where municipalities may implement GSI projects in the future. GSI projects can provide multiple benefits including improving water quality, reducing local flooding, enhancing habitat and urban greening, augmenting water supply, and providing climate change resiliency. GSI can also be integrated into projects that improve urban streetscapes, enhance pedestrian and bicycle safety, and provide traffic calming.

Attend this workshop to learn about local GSI Plans and requirements, the Santa Clara Basin Stormwater Resource Plan which informed the GSI Plans, resources available to consultants for integrating GSI into public projects, and how these plans and requirements may influence public and private development in the Valley.

There will be no charge for the workshop. Light breakfast will be served.

Santa Clara Valley Urban Runoff Municipal Regional Stormwater Permit Pollution Prevention Program . Large urban areas covered by countywide . Fifteen Santa Clara Valley agencies work together through stormwater permits since 1990 SCVURPPP to prevent stormwater pollution . Six countywide permits combined into one . SCVURPPP agencies are part of the Municipal Regional Municipal Regional Permit, effective Stormwater Permit (MRP) that covers urban Bay Area counties Dec. 2009, reissued Nov. 2015 . SCVURPPP and its member agencies implement regulatory, . Permit contains private and public land monitoring and outreach measures aimed at reducing pollution in development requirements and green urban runoff stormwater infrastructure (GSI) planning requirements . Other provisions contains requirements for reducing loads of certain pollutants of concern in stormwater (e.g., mercury, polychlorinated biphenyls (PCBs), pesticides, and trash)

Green Stormwater Infrastructure Typical Bioretention Design . Systems that use vegetation, soils, and natural processes to capture and treat stormwater . Most urban GSI involves retrofitting public streets, roofs and parking lots to divert runoff to: . Vegetated areas (“stormwater planters” or “stormwater curb extensions” . Pervious pavements . Rain gardens (“bioretention areas”) . Infiltration areas . Cisterns and rain barrels

Fact Sheet: Greening Our Streets, Buildings, and Parking Lots

Santa Clara Valley Urban Runoff Pollution Prevention Program, 2016

Greening Our Streets, Buildings, and Parking Lots

What is Stormwater Pollution? In natural landscapes, most of the rainwater soaks into the soil. However, in our urban areas, paved surfaces such as driveways, sidewalks, roads, and streets prevent rain from soaking into the ground. As rainwater flows over these surfaces, it can pick up pollutants such as motor oil, metals, pesticides, and litter. It then carries these pollutants into storm drains which flow directly to local creeks and the San Francisco Bay, without any cleaning or filtering to remove pollutants.

Green Stormwater Features Can Reduce Flow and Pollution Cities and towns in Santa Clara Valley are working together to create sustainable or green streets, buildings, and parking lots that mimic natural landscapes, by incorporating green stormwater features. These features allow rainwater flowing over buildings, streets, and parking lots to soak into the ground and be filtered by soil. This reduces the quantity of water and pollutants flowing into storm drains Street runoff flowing into vegetated areas that capture and treat polluted and local creeks. stormwater (Image courtesy of Callander Associates and the City of Campbell)

What are Green Stormwater Features? The following green stormwater features are being integrated into local projects:

Spreading Stormwater Runoff into Landscaping Landscaped areas can be designed to collect stormwater runoff from building roofs and paved areas. Stormwater soaks into these areas, and pollutants are filtered out or broken down by the soil and plants.

Bioretention Areas or Rain Gardens Bioretention areas or rain gardens are landscaped areas that use a special soil mix to remove pollutants from stormwater runoff. They are planted around buildings, in parking lots, curb extensions, park strips, traffic circles, along street edges, and in medians.

Rainwater Harvesting Rain barrels or cisterns can be used to collect and store rainwater for use in landscape irrigation and toilet flushing.

Green Roofs Building roofs covered in soil and vegetation enable rain water infiltration, storage, and evapotranspiration. In addition to stormwater benefits, Green Roofs can also mitigate urban heat island effects while improving air quality and building energy efficiency.

Pervious Concrete, Porous Asphalt, and Pervious Pavers Pervious surfaces let rain soak into the soil. They are generally used in crosswalks, sidewalks, plazas, driveways, parking spaces, street edges, and emergency vehicle access lanes. Pervious surfaces include the following: • Pervious concrete or porous asphalt • Grid pavers with gaps filled with gravel or turf • Interlocking pavers made of pervious material • Solid interlocking pavers that have gaps between them

Pervious pavers at Rosita Park, Los Altos

How You Can Use Green Stormwater Features in Your Yard, Garden, and Neighborhood • Replace concrete in driveways, patios, and walkways with pervious pavers. • Build a rain garden. The native and drought-tolerant plants used in rain gardens reduce the need for irrigation, and attract beneficial wildlife like butterflies and hummingbirds. • Install a rain barrel to capture rainwater for landscape watering. • Direct rain gutter downspouts to landscaped areas instead of concrete driveways. • Support your local municipality’s efforts to include green stormwater features in neighborhood improvement projects. • Take a tour of local buildings and streets that include green stormwater features.

Fact Sheet: Integrating Green Infrastructure into Public Streets, Roads, Buildings, and Parking Lots

Santa Clara Valley Urban Runoff Pollution Prevention Program, 2016

Integrating Green Infrastructure into Public Streets, Roads, Buildings, and Parking Lots

In natural landscapes, rain that falls on the ground mostly soaks, or infiltrates, into the soil. However, in urban areas, impervious surfaces such as roofs, pavement, and streets, prevent infiltration. This results in an increase in stormwater runoff and pollutants flowing into storm drains, local creeks, and the Bay.

To reduce the impact of urban development on waterways, local municipalities are now required to develop and implement Green Infrastructure (GI) Plans for incorporating Low Impact Development (LID) designs into new and existing drainage infrastructure on public properties and rights-of-way, including streets, storm drains, parking lots, and building roofs. LID designs reduce stormwater runoff and mimic a site’s predevelopment hydrology by minimizing impervious cover, and infiltrating, storing, and/or biotreating stormwater runoff. This reduces the quantity of runoff and pollutants flowing into storm drains and local creeks.

Image: Street runoff flowing into vegetated areas that capture and infiltrate stormwater (Image courtesy of Callander Associates and the City of Campbell) Regulatory Requirements The Federal Clean Water Act and State regulations require municipalities to obtain permits to discharge stormwater from municipal storm drain systems. The Municipal Regional Stormwater Permit (MRP) covers 76 agencies in the Bay Area. In Santa Clara Valley, 15 local agencies (Co-permittees) collaborate through the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) to implement MRP requirements. Since 2011, Provision C.3 of the MRP has required public and private development projects that create and/or replace 10,000 square feet or more of impervious surface (5,000 sq. ft. for highly polluting land uses) to provide LID site design and stormwater treatment measures. Beginning in 2016, each Co-permittee is also required to: • Evaluate all public projects, regardless of size, to identify opportunities for integrating LID measures. • Prepare and maintain a list of public projects that may have the opportunity to integrate GI elements. • Develop and implement a GI Plan describing how local impervious surface areas will be built or retrofitted over time to disperse, capture, infiltrate, and/or treat runoff on-site, or before it enters the storm drain system. • Develop a framework (work plan) for developing a GI Plan, and have it approved by a local governing body by June 30, 2017. • Complete a GI Plan and submit it to the Regional Water Quality Control Board by September 30, 2019. • Amend policies, ordinances, and planning documents to support the implementation of the GI Plan. • Conduct outreach to the public, municipal staff, and elected officials.

Opportunities for Green Infrastructure Potential Green Infrastructure Benefits Some projects that offer opportunities to integrate GI include: . Improved water quality . Improved wildlife habitat • Roadway narrowing for traffic calming and safety (“road diets”) . Reduced flooding • Improvement of bicycle and pedestrian facilities . Increased water supply • Replacing or adding pavement or drainage structures . More pleasant urban environment (including gutters, inlets, or pipes) . Traffic calming • Reconstruction of parking facilities . Safer pedestrian and bicycle facilities • Landscaping and street beautification, including tree planting . Increased property values • Streetscape and intersection improvements . Improved air quality and climate resiliency • Modifications or improvements to public building areas This fact sheet was developed by the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP).

Green Infrastructure Measures The following low impact development measures can be integrated into public infrastructure projects:

Dispersion of Stormwater Runoff into Landscaping Landscaped areas can be designed to collect stormwater runoff from building roofs and paved areas. Stormwater infiltrates into these areas, and pollutants are filtered out or broken down by the soil and plants.

Bioretention Areas or Rain Gardens These landscaped areas collect, treat, and infiltrate runoff using plants and a specified soil mix. Biotreatment areas can be incorporated into parking lots, curb extensions, park strips, traffic circles, and street edges and medians. Planter boxes next to buildings, tree wells, and tree trenches can also be designed as biotreatment areas.
