The Plan has undergone several stages of review and comment including: ■ Three public meetings were held to present initial findings and recommendations and those comments were incorporated. ■ Ecology has provided their review and comments. ■ The Board provided input on retrofit project selection last year which was incorporated. We are now seeking one last Board review prior to finalizing the plan. BACKGROUND: Public Works contracted with Herrera Environmental to prepare the Belfair Stormwater Basin Plan. This work was funded through an Ecology grant and local match from Public Works,The Hood Canal Salmon Enhancement Group and Mason Conservation District. The grant is now closed out and all that remains are final revisions and Plan adoption. A project summary is attached. SUMMARY OF PLAN RECOMMENDATIONS: Plan recommendations are identified as either capital improvement plans (CIP) or programmatic. It is important to note that all recommendations are discretionary. The CIP list projects are all retrofits, meaning they address impacts from past development and are not required. There are no CIP projects to address future development, as modeling has shown adoption of the 2014 Stormwater Management Manual for Western Washington (SWMMWW) will mitigate future development impacts with two minor exceptions. Mason County is not a Municipal Stormwater Permittee so the programmatic recommendations are also discretionary. Recommendations for each category are attached. While the Plan recommendations are considered discretionary, with a Water Quality Improvement Plan in place for the Union River and impaired fresh and marine water bodies within the Belfair area, it is advisable to continue implementing stormwater management activities. WHAT NEXT: Staff requests the Board's input on Plan recommendations and implementation. Once final edits are completed, Public Works recommends adopting the Plan to improve future grant application success.

The county, along with project partners Hood Canal Salmon 1� Enhancement Group, Mason Conservation District and consultant Herrera. completed a basin plan, retrofit project design, and conducted public education, outreach and engagement with this Ecology grant. Ecology personnel were instrumental in providing technical reviews and guidance. FOrWetland in Belfair Implementing the stormwater management plan recommendations will contribute to the goal of removing the Union River, Belfair Creek and Hood Canal from water quality impaired listings. Project Accomplishments • Data was compiled and characterized along with "Minhydro layer updates. -- ' A Quality Assurance Project Plan (QAPP) was prepared. • Models were developed to identify whether a change in stormwater management manuals will improve water quality and the environment, and if additional measures are needed. ■ Potential public infrastructure retrofit sites were evaluated and prioritized. • One retrofit project pre-design report was prepared. ■ Public information and outreach was conducted for two purposes: to engage the public in the Plan, and to further promote LID strategies. ■ A basin plan was completed identifying candidate CIP retrofit sites and enhancements to the current stormwater management program. Water Quality Improvements V Anticipated, long-term water quality improvements include: ■ Stormwater pollutant loadings to the Union River, - Belfair Creek and Lynch Cove listings will be reduced. y ■ Pollutants entering the wetlands and smaller streams , will be reduced through improved source control and maintenance practices. • Habitat and hydraulic function within the Belfair area will be protected and enhanced, thereby contributing (t:ipection and technical assistance improves to overall improved water quality. source control, construction and maintenance practices. The Next Step for Continued Success Continued success relies on implementing several plan recommendations including: • Adopting the most recent version of the Stormwater Management Manual for Western Washington • Expanding system mapping to include private facilities and conveyance attributes ■ Updating Illicit Discharge code language • Increasing monitoring of private system maintenance ■ Constructing public infrastructure stormwater retrofits in conjunction with other programmed projects ■ Promoting and when possible, incentivizing private stormwater retrofits • Continuing local source control program activities • Documenting and reporting stormwater management activities Lessons Learned --- — - --- - Despite robust scoping of the modeling effort, this was a very time consuming task with many iterations. _ _ ° t!.

While this project was not the highest rated, it was selected for more detailed concept design development because of the timing of an associated County sidewalk improvement project planned for Old Belfair Highway. This retrofit project would be implemented in conjunction with the sidewalk improvement project and would provide stormwater runoff ' treatment for the roadway. This project would retrofit an existing stormwater ditch with a `w bioretention system to provide water quality treatment and infiltration of stormwater in a high traffic location in downtown Belfair.

HERRERA February 2018 54 DRAFT Belfair UGA 2018 Basin Plan STORMWATER PROGRAM RECOMMENDATIONS The County is in the enviable position of not yet falling under the NPDES Phase II permit and therefore being able to adopt a phased and strategic approach to addressing existing and future stormwater concerns. While there are water quality concerns, there are no critical flooding or safety issues, therefore the emphasis on stormwater management should be on preventing pollution and establishing the building blocks that are essential to an effective *' management program and that reflect the framework of the NPDES Phase II permit. 'N Building blocks consist of such things as; updating stormwater ordinances, developing a stormwater system map and inventory, -' •- ' :SSR-I providing focused public education on priority areas, supporting existing programs, and Stormwater Quality providing incentives where feasible. --" -- -�-- —J Table 15 provides a general summary of the basic components of the permit, the key requirements of those components and recommendations for the Belfair area. The sections following Table 15 lay out a series of stormwater program recommendations. Implementation of these recommendations would also help to meet one of the key goals of the County's Comprehensive Plan to protect the quality of the environment.

W HERRERA February 2018 58 DRAFT Belfair UGA 2018 Basin Plan Flow Control As documented through the modeling effort, Mason County's existing LID ordinance and Ecology's 2012 manual are essentially equivalent in terms of flow control and potential flooding associated with build-out of the UGA. However, the existing ordinance is too prescriptive, allowing little flexibility for developers in terms '�- of how best to meet flow control needs. More important, the existing ordinance requires application of the same LID requirements throughout the UGA: including where there are ` poor soils, landslide hazards, and other { underlying factors that should preclude or Example LID BMP:Bioretention minimize use of infiltration based stormwater control. Recommendation(s): • Adopt Ecology's 2012 manual. (Note: Revisions to Mason County Code are already in progress related to this recommendation.) Source Control The most effective mechanism for reducing contaminants in stormwater and receiving waters is to eliminate or reduce the sources of contaminants in the watershed. The current NPDES Permit has many requirements related to implementation of illegal discharge detection and elimination (IDDE) program. Some of these elements should be adopted for the Belfair UGA. With the possible exception of bacterial contamination, commercial businesses and roadways are the most likely sources of contaminants. The County currently maintains an agreement with Kitsap County to carry out these activities in the Belfair area. Recommendation(s): • Continue to support the agreement with Kitsap County to conduct source control training and outreach. Fund the Stormwater Utility There are permanent, long term needs associated with managing the stormwater system in the UGA. Most of those needs cannot be met through existing funds or through grant programs. While Mason County adopted an ordinance that establishes a stormwater utility in the Belfair UGA, they have not adopted a utility rate to support it. Even a low utility fee would allow the February 2018 H E R R E RA DRAFT Belfair UGA 2018 Basin Plan 59 County to begin building a program that would meet some of the essential needs of an effective program and to prepare for future growth. In the absence of a dedicated funding mechanism, the County's general fund or roads fund should be used to meet the highest priority needs identified by this plan. Recommendation(s): • Fund the stormwater utility. Public Stormwater System Conveyance System Inventory and Assessment Although most of the public stormwater structures have been inventoried in the Belfair area, the conveyance system including pipes and ditches has not been adequately inventoried or assessed. Managing the stormwater system in the Belfair UGA is made more difficult by the lack of this information. For example, the modeling done for this project could not be used to predict actual flooding potential or pinch points in the conveyance system due to lack of infrastructure data on such things as cross-sectional area and invert elevations. Likewise, a maintenance program for the system is difficult to generate without first creating an inventory. The UGA is primarily served by a network of open channel ditches that provide stormwater conveyance on public and private property. This ditch system may be especially problematic. These are not mapped, are not typically included as part of routine maintenance activities, and are often modified by private property owners without notification. It is unknown the extent to which they may be providing stormwater treatment or control. Recommendation(s): • Implement a program to map the conveyance system in the UGA over a 1- or 2-year period, and make initial assessments of the drainage area served by each. • There are regional studies planned to develop a rating and classification system for ditches based on risk and maintenance needs. The County should support these studies and apply the findings to develop a specific plan and policies to cover maintenance of this part of the stormwater system. • The County should continue to inspect and maintain the drainage systems associated with the County road system. (As outlined in the recommendations package from the Stormwater Task Force [SWTF] in 2012.) • The City should continue to be proactive in leveraging planned capital facilities projects to include stormwater system upgrades and repairs. It HERRERA February 2018 .' DRAFT Belfair UGA 2018 Basin Plan Public System Retrofits One of the inherent problems with relying upon the existing stormwater management manual and revisions to ordinances and regulations is that they only influence new development or substantive redevelopment. Thus, even if fully implemented the most they can do is help to maintain the status quo in terms of flow, water quality, and habitat. Retrofitting existing development is one way to improve conditions associated with the existing developed environment. The County must be proactive in identifying retrofit opportunities as part of all routine County construction projects. The County's roadway construction program is the largest likely source of retrofit opportunities. Recommendation(s): • The County's CIP program should be reviewed annually and all major construction activities should be evaluated to identify retrofit opportunities. Private Stormwater System Private Stormwater System Inventory As the UGA builds out there will be an increasing number of stormwater treatment and control facilities that are privately-owned. Although there are currently no requirements that the County have an inventory of these facilities, it makes good sense to begin development of an inventory program since the information can be collected as part of the site development review process. This is information that is difficult to obtain retroactively, so it is in the County's best interests to begin collecting it as soon as possible. This inventory is also needed to develop an understanding of how much stormwater is currently being controlled and then to estimate how much benefit could be achieved from retrofit of existing development and where best to focus efforts. Recommendation(s): • The County should revise their submittal requirements to include detailed information on stormwater facilities and be sure those are provided in record drawings at project completion. • A private stormwater facility inventory database should be developed and a process implemented for insuring all new facilities are included in the inventory.

These facilities .. S# require routine maintenance to perform properly. The County requires submittal of operations and maintenance manuals for all >. engineered facilities, but there is currently no program in place to ensure this is occurring. The current Phase II permit requires these facilities be inspected every year and maintained when ' necessary, thus eventually this will be required in the UGA and it is practical to begin building the Inventory of Stormwater Systems program. Recommendation(s): • The County's website should be updated to include information on the importance of stormwater facility inspections and maintenance needs and requirements. The website should include appropriate checklists and BMP details to assist private property owners. • The County should require project proponents to submit operations and maintenance manuals for all parts of their stormwater system as a part of the design review process. • The County should consider requiring maintenance inspection forms be submitted every year for all new private facilities and require evidence of maintenance when it has been done. Promote Private Stormwater Retrofits One of the inherent problems with relying upon the existing stormwater management manual and revisions to ordinances and regulations is that they only influence new development or substantive redevelopment. Thus, even if fully implemented the most they can do is help maintain the existing condition in terms of flow, water quality, and habitat. Damage from past development will not be impacted. Even if the County took a very proactive role in providing for stormwater retrofits on their property, publicly-owned property is only a small part of the picture. Therefore, any significant improvement over existing conditions would require retrofits on existing private property. Typical techniques for promoting retrofits is to provide education and technical support, although some communities offer financial incentives such as rebates on rain barrels, reimbursement for some of the costs for raingarden construction, and in some cases a reduced stormwater utility fee. Mason County is already providing support to educational and technical assistance programs and these efforts should be continued as recommended below. V HERRERA February 2018 62 DRAFT Belfair UGA 2018 Basin Plan Recommendation(s): IS Promote use of raingardens and roof downspouts for private residents through providing educational workshops for designing rain gardens, direct technical support for design, and permit review streamlining. • Continue supporting WSU Cooperative Extension and Mason Conservation District programs to provide assistance to homeowners and businesses for smaller scale stormwater retrofit and nonpoint source control projects. (As outlined in the recommendations package from the Stormwater Task Force (SWTF) in 2012.) Incentivize Connections to Wastewater System The community has a state-of-the-art wastewater treatment system that is under-utilized and at the same time the area streams continue to have bacteria problems, likely at least partially due to septic system failures. However, it is costly to hook up to the system, this coupled with long term utility bills are a large disincentive for voluntary hookups. One of the key recommendations identified by the SWTF was to establish a system to inventory, track, and assess maintenance for on-site septic systems and this program is now in place. Recommendation(s): • Require that septic systems be inspected and tested every 3 years and require that this information be filed with the County. Associate an impact fee with all poorly performing systems. • Require hookup to the wastewater system within the established service area if there is any substantive remodeling and whenever a house is sold. • Consider cost-share programs to cover the initial hookup fees. Focus outreach efforts on the areas with known poor soils. Enforce Development Regulations As described in the documentation from the SWTF (2012), new development (and redevelopment) can greatly impact surrounding property and the natural environment unless adequate protection is in place. Development codes and regulations, project review and inspection, and enforcement are all important ways to ensure that "growth pays for growth," and will reduce the need for expensive retrofits. Further, without enforcement of regulations, the regulations are not applied equally and the long term burden for problems is likely to fall to County residents rather than project proponents.The SWTF felt strongly that the County needed to ensure "first and foremost" compliance with existing regulations.Their specific recommendations included: February 2018 HERRERA DRAFT Belfair UGA 2018 Basin Plan 63 • Restore a code compliance position to assist with enforcement. (Note: Progress has already been made in relation to this recommendation and a code compliance position has been reestablished.) • Evaluate current codes, development processes and fees and refine language and practices where needed. • Continue to require project inspections by the engineer of record (rather than County- performed inspections). • Continue the use of stormwater checklists (rather than County-performed plan review). Support Clean Water Program Many of the recommendations developed during this planning effort would benefit if they all fell under the umbrella of an overall program and a related staff position to coordinate a county-wide "Clean Water Program." Public education and outreach, technical assistance, coordination with partners, water quality monitoring, oversight of TMDL implementation, and preparation �,a,CRE" for eventual NPDES compliance are a few of the key tasks that could be associated ' with this program/position. This was also -+ a recommendation in the Stormwater Task Force's 2012 assessment (SWTF 2012). However, without funding of the e stormwater utility it is not practical at this time to support creation of a new __ Identifying Habitat improvement Opportunities position or monitoring program. Recommendation(s): • Continue to support the County health department's pollution identification and control (PIC) program. • Continue to partner with the HCSEG and LWCCC to promote local education and outreach about stormwater and other water quality issues. • Expand links to public education and outreach materials on the County's website to take advantage of materials and tools already available. N HERRERA February 2018 64 DRAFT Belfair UGA 2018 Basin Plan Long-Term Riparian Corridor Acquisition Even with full enforcement of regulations on new or redevelopment projects, the legacy problems associated with past development will not be significantly impacted. Therefore, to improve already degraded water quality or habitat conditions, a more proactive approach is required. Recommendation(s): • Support existing programs spearheaded by groups such as the Hood Canal Coordinating Council and the Hood Canal Salmon Enhancement Group for long term acquisition and protection of the riparian corridor.
