COG recommended awarding $262,500.00 to the City of Roslyn. After opening construction bids for the stormwater improvements project, construction bid numbers were significantly higher than the Engineer's Estimate. In July of 2022, the City of Roslyn requested to combine 2017 funds to the original 2022 fund award of $262,500.00 under Resolution 2022-128 to cover overage costs, however, the project requires an additional amount of $250,000.00 to award and construct the project. The Board of County Commissioners elected to award an additional $250,000.00 to the City of Roslyn under Resolution 2022-142 for award and construction of the stormwater improvements project. An amended 2022 Distressed County Sales and Use Tax Infrastructure Improvement Program Agreement is required to capture the new funding amount from the Fund 108 (Distressed County Sales and Use Tax for $512,500) and has been executed by the City of Roslyn.

Project Description: Describe the scope of work. Indicate the major work involved, including a brief comparison of existing and proposed conditions. The City of Roslyn drains to Crystal Creek, an impaired waterbody. The Stormwater Retrofit and CIP Construction will include a city-wide installation of low impact development (LID) best management practices (BMP) to improve water quality as part of the CIPI Project and in line with implementation of the City's planned capital improvement projects (CIP). The project will include stormwater retrofits for improved water quality in conjunction with the on-going CIP I, a funded pipe rehabilitation project currently at 90% design. The goals are to construct BMPs that will improve flow control and reduce flooding and pollutant discharges to the impaired waterway within the City of Roslyn, Crystal Creek. Overal I the City is requesting $262,500 for construction to complete a project where the total costs will be approximately $3 -million dollars. The attached Figures include the project area. The attached Schedule and Budget include detailed Tasks for the Scope of Work. The attached Stormwater Comprehensive Plan addendum includes detailed project information. 2. Explain how the infrastructure project will helpmeet the economic development goals of your community and/or region. If this project is not done, will the anticipated private development still take place? The City currently experiences flooding in the downtown core due to undersized stormwater drains, and adverse environmental impacts from the lack of water quality treatment within the same drainage basin. The infrastructure project will help meet the economic development goals of the community by providing an adequate stormwater system that will allow growth. Private commercial development is not currently planned within the drainage basin as any new commercial development or redevelopment is limited by the capacity of the stormwater system. If the infrastructure project is not done the economic development goals for the City will continue to be limited. 3. Indicate if the project is consistent with the following applicable state, regional and local plans and prioritization processes: ❑ Overall Economic Development Plan — Officially Adopted ® Comprehensive Land Use Plan — Officially Adopted 2019 r Capital Facility Plan — Officially Adopted 2019 ❑ Community Action Plan (or other community-based plan) — Officially Adopted ❑ Six -Year Transportation Improvement Plan — Officially ❑ Site-specific development plans; e.g., Community Master Plan — Officially Adopted ❑ Other 4. Public Benefit: Please describe the public benefit derived from project completion. The public benefits not only from the economic development opportunities, but also from the protection of surface water bodies as road runoff from the urban area is treated through bioretention before discharging into Crystal Creek. In addition, there is recognition that treating road runoff does prevent contaminants from reaching surface water bodies, protecting both human and wildlife from exposure to toxins that can be lethal to aquatic life or accumulate in fish, wildlife and human tissue. 6. Define the total number of project partners demonstrating project support. The Department of Ecology is currently the only partner and providing 85% of the funding. 6. Explain how construction ready this infrastructure project is relative to design completeness and the permitting process. Design Completeness - The alternatives analysis has been completed and the design is currently fully funded with the Consultant (Mead&Hunt) preparing to submit the 30% level Plans and Specifications to the City and Ecology for review. Permitting Process - The project is in the review process for the Inadvertent Discovery Plan and preparation of the SEPA Checklist. Survey work has already been completed and the geotechnical investigation work is planned for December 2021. 7. Indicate the Estimated Number of Short Term and/or Permanent Jobs Created/Retained by the Project. Estimated Short Term Jobs created by the project would include jobs for consultants and contractors. Consultant teams include at least (2) archaeologists, (2) geotechnical/soils professionals, (3) surveyors, (3) design engineers. Contractor jobs are anticipated to be in the 15-20 range for tradespeople including subcontractors. The infrastructure project allows for the creation of development and/or redevelopment within the drainage basin. Permanent jobs are anticipated as part of any development after the infrastructure project is completed. Per Chapter 5 (Economic Development) of the City's Comprehensive Plan the employment capacity is an additional 202 jobs.

Introduction 1.1. Project Purpose The City of Roslyn (City) completed a Stormwater Comprehensive Plan (Plan) in July 2014. The Plan contains structural and non-structural solutions to address stormwater conveyance and water quality problems within the City. The Capital Improvement Plan (CIP) contained within the Plan identifies various structural solutions to address conveyance issues by replacing pipes and culverts. Nonstructural solutions such as stormwater management facility inspection, public education and outreach, water quality monitoring and encouraging infiltration and low impact development are aimed at improving water quality within the region. The City received a Water Quality Grant from the Washington State Department of Ecology (Ecology) to identify ways to improve water quality within the local waterway, Crystal Creek. The goal is to identify Best Management Practices (BMPs) to provide stormwater runoff treatment for Total Suspended Solids (TSS) and provide for reduction in other pollutants within the urbanized areas of the City. The grant has two objectives: 1. Evaluate the possible implementation of stormwater retrofits to provide water quality treatment and determine the most suitable locations, methods, estimated costs, available funding, and phased approach for such retrofits in a citywide study. 2. Advance design of stormwater treatment retrofit improvements for the CIP 1 project which is a pipe rehabilitation project currently under design. 1.2. Report Purpose This report documents the citywide study to be adopted as an addendum to City of Roslyn Stormwater Comprehensive Plan. The CIP 1 treatment project will be advanced in detail design after study completion. This addendum describes the drainage basin, details of the project site, an analysis of the core elements, the alternatives considered, the design analysis, a quantification of the water quality benefit, CIP summaries, financial review of potential funding, and operation and maintenance considerations. 1.3. Design Codes and References 1.3.1. Department of Ecology The analysis will be in accordance with Ecology's Stormwater Management Manual for Eastern Washington (SWMMEW), 2019, and Ecology's Design Deliverables for Stormwater Projects with Ecology Funding, June 2018. 1.3.2. City of Roslyn This analysis will be in accordance with the City's Stormwater Regulations listed in Chapter 3 of the Plan. 2. Basin Description 2.1. General The study area lies within the Upper Yakima River watershed, Ecology Water Resource Inventory Area (WRIA) 39, where it drains into Crystal Creek and ultimately reaches the Yakima River in central Washington, near Cle Elum. The creek serves as a recreational stream, and is protected for salmonid spawning, rearing, and migration. Crystal Creek is a 303(d) listed stream and has Total Maximum Daily Load (TMDL) limits for fecal coliform, temperature, and sediment. 2.2. Historic and Existing Conditions The citywide study basin area encompasses 1,170 -acres draining to Crystal Creek as shown in the attached Exhibit 1 (Mead & Hunt, October 2019). This study basin area is composed of 50% -forested hills to the north of the City limits, and a mixed land use of low density residential, medium density residential, commercial, light industrial, and historic zones within City limits. The existing stormwater conveyance system was built as the City developed, and includes a combination of open ditches, pipes, catch basins, and culverts. The system was originally built as a combined sewer system but was later converted into dedicated storm sewers by the mid -80s. Major trunk lines were constructed as bypass systems to contain three creeks that historically flowed through the City. The City's Plan includes an inventory of the City's drainage infrastructure and proposed capital improvement projects primarily intended to address capacity issues within the City. The City generally lacks any stormwater runoff treatment. Since development of the Plan, CIP 2 project (a box culvert crossing South A Street) was completed in 2017. CIP 1 project (a bypass pipe to alleviate a bottleneck on a main storm trunk line) is currently under design development and scheduled for bidding and construction in 2022. The CIP 1 basin, a subbasin of the citywide study basin, is an 804 -acre area that currently discharges to Crystal Creek via one outfall south of East California Avenue. The CIP 1 basin is mostly forested hills with some urbanized development, including commercial, residential, light industrial, and historic uses from the City. The coal mine within the project area is no longer in use. The CIP 1 basin drains southward in a piped storm drain system along North First Street before it discharges into Crystal Creek. 2.3. Proposed Conditions The citywide study does not propose any changes to the land use, basin delineations, soils or water bodies. The proposed retrofits for stormwater treatment in the study area will capture stormwater flow from existing topography before flowing through underdrains and into the existing storm drain system. 3. Project Site Description 3.1. Project Limits The project site for the stormwater retrofit study area is intended to capture the urbanized areas within the Stormwater Retrofit Study Area shown in Exhibit 1 and Exhibit 2. The project site is a 270 -acre area of developed lands within the City that discharge to Crystal Creek, and consists of commercial, residential, light industrial, public facilities and historic uses. The drainage subbasins delineated in the Plan were carried forward for this analysis. The potential locations identified for stormwater retrofits were reduced to exclude the restricted buffer area per Policy H2.5 of the City of Roslyn, which specifies that "all lots within 300 feet of wetlands shall be 50 acres or larger. No building or development is permitted within 300 feet of wetlands." This area was further reduced to remove the unsewered areas of the City. The resultant Treatment Assessment Area measures approximately 152 acres and is shown in Exhibit 2. The CIP 1 Treatment Assessment Area is shown in the attached Exhibit 2 as the urbanized tributary area for the CIP 1 treatment project and measures approximately 45 acres. The CIP 1 treatment project will advance design of the treatment facilities within the CIP 1 Treatment Assessment Area. Final design and construction will be done under separate grant funding. The CIP 1 Treatment Assessment Area drainage subbasins were subdivided into smaller subbasins to aid in a more detailed analysis for design advancement and quantification of the water quality benefit. The drainage areas and existing impervious areas are listed in Appendix A for each subbasin shown in Exhibit 2. 3.2. Project Site Conditions The land use is predominantly urbanized, including commercial, residential, light industrial, and historic uses from the City. The site generally slopes from northwest to southeast towards Crystal Creek. There are significant elevation differences throughout the City. The tax parcels (and public right-of-way) were obtained from the Kittitas County COMPAS database. The topographic contours were obtained from the Washington State UDAR portal, Kittitas County FEMA Study conducted in 2011 (https:/ilidarportal.dnr.wa.gov/#47,23423-120,99578 15). There are wetlands to the west and southeast of the Treatment Assessment Area. Wetlands exist south of Roslyn Pioneer Park, north of Whitehead Road where Crystal Creek crosses the road, and south of Whitehead Road. The wetland boundaries and associated layers were obtained from the Plan. The soils within the project site are mostly Roslyn ashy sandy loam with a Hydrologic Soil Group of B, and Teanaway ashy loam with a Hydrologic Soil Group of C. There are also some dumps and mine sediment with a Hydrologic Soil Group of D according to the Gridded Soil Survey (gSSURGO) Database. The climate is heavily influenced by the adjacent mountain ranges and elevation. Precipitation is higher in the winter than the summer. The Plan provides more details regarding average monthly 3 climate data. For the stormwater retrofits, the water quality design storm is based on the 6 -month, 3 -hour in accordance with the SWMMEW (Ecology, 2019). 3.3. Stormwater Features The existing storm sewer mapping was developed with the Plan. It includes a storm sewer network of clay and PVC pipe, catch basins, manholes, and a ditch. The majority of the urbanized developed area within the City drains to a main storm sewer trunk line discharging to a 200 -foot -long ditch south of East California Avenue. This ditch flows into Crystal Creek east of East Hoffmanville Avenue. The area south of California Avenue lacks storm sewer infrastructure. 4. Core Element Analysis Ecology expects a Core Element analysis for all projects, even if the project is a retrofit. Ecology uses this analysis to determine project eligibility for funding. This site is considered redevelopment in accordance with Section 2.6 of the SWMMEW (Ecology, 2019). The project does not include any changes to land use or additional impervious areas. Furthermore, the project does not propose replaced impervious surfaces. Therefore, according to the flow chart in Figure 2.2 of the SWMMEW (Ecology, 2019), the Core Elements #2 and #3 apply to the land disturbed. The project does not require Preparation of a Stormwater Site Plan (Core Element #1), Preservation of Natural Drainage Systems (Core Element #4), Runoff Treatment (Core Element #5), or Flow Control (Core Element #6). Ecology has established a procedure to quantify the water quality benefit for retrofit projects. A baseline is determined based on what would be required if the project was to meet new/redevelopment standards. The project does not require Runoff Treatment (Core Element #5) or Flow Control (Core Element 46) being this a retrofit project. The water quality benefit expected under this retrofit project is described later under Section 7. 5. Alternatives Considered The study identifies Best Management Practices (BMPs) to provide stormwater runoff treatment for Total Suspended Solids (TSS) and provide for reduction in other pollutants within the urbanized areas of the City. The alternatives considered for this study are intended to meet these design objectives. Priority is given to Low Impact Development (LID) BMPs that accomplish both flow control and runoff treatment, although runoff treatment is the focus of the retrofits. Table 1 provides a summary of the considered alternatives along with descriptions, benefits, limitations, and recommendations regarding preferred alternatives. Table 1: Alternatives Analysis Alternative Description Discussion / Recommendation 1 — Biofiltration Swales ❑ Construct biofiltration ❑ Provides runoff treatment for public swales adjacent to paved right-of-way roadways ❑ Provides minimal flow control benefit ❑ Connect underdrains and ❑ Designs require consideration of cold overflow bypass from climate biofiltration swalesto existing stormrm sewer sew ❑ Impacts roadside parking network ❑ Designs can have minimal impact on the landscape with the appearance of open roadside ditches ❑ Considered the preferred alternative in areas with storm sewer 2 — Vegetated Filter ❑ Construct vegetated filter ❑ Provides runoff treatment for public Strips strips adjacent to paved right-of-way roadways ❑ Provides minimal flow control benefit ❑ Design can be used in unsewered areas ❑ Designs can have minimal impact on the landscape ❑ Impacts roadside parking ❑ Considered the preferred alternative in unsewered areas 2 — Oil Water ❑ Construct and connect oil ❑ Low water quality benefit as traffic Separators (OWS) water separators to the usage on roadways does not warrant storm sewer installation of OWS ❑ No flow control benefit ❑ Not considered the preferred alternative. 3 — Pervious ❑ Construct new pervious ❑ Provides runoff treatment and limited Pavement pavement flow control ❑ Demolish existing pavement ❑ Unable to infiltrate with poor soils ❑ Connect underdrains to ❑ Construction would cause significant existing stormwater sewer disruption to neighborhood system ❑ Not considered the preferred alternative. 4 — Detention Basin w/ ❑ Use underground ❑ Provides runoff treatment and flow Filter Cartridges engineered filter systems to control provide water quality ❑ Filter cartridges are a large capital treatment cost and large annual maintenance cost ❑ Scalable treatment provided at existing collection points or central treatment location ❑ Not considered the preferred afternative. 5 6. Design Analysis 6.1. Existing Stormwater Drainage System An existing hydrology and hydraulics XPSWMM model from the Plan was used for the analysis of this study. Before using this model, various hydrological parameters were reassessed and updated to model the existing conditions of the drainage basins associated with this study. Subbasins within the project site were modified to follow the topography of the City rather than grouped tax parcels. In reassessing the subbasins, new flow paths were created for each subbasin. Land uses within each subbasin were updated and used to calculate new Curve Number (CN) values and new times of concentration (Tc). The resulting subbasin parameters can be found in Appendix A For the stormwater retrofits, the water quality design storm is based on the 6 -month, 3 -hour storm event in accordance with the SWMMEW (Ecology, 2019). The resultant flow rates for each basin can be found in Appendix B. 6.2. Proposed BMP Design and Improvements The preferred alternative includes the implementation of biofiltration swales and vegetated filter strips for stormwater treatment in the Treatment Assessment Area. This option allows the stormwater treatment facilities to be dispersed around the City, treating runoff as close to the source as possible. Additionally, the preferred alternative provides the least amount of disturbance to the historical integrity of the City by adhering to the historical preservation guidelines of preserving sidewalks, fences, and trees when at all possible. These vegetated facilities will be designed to be compatible with the climate and region. These facilities are depicted in the following figures extracted from the SWMMEW (Ecology 2019): [M[,aLL %0iE6' u,ararnerl r✓ary ' ] � r-aa.na �ar.a♦.vas l �%✓ Ar.aa♦f avprvN ✓f J `N9e�nr a'ry aefee rry Nra, M'rM IJ Gripin`iypa�y ybn,vrtra•a• IfirygCMpYrr,fr FIGURE is 810FILTRATION SWALE ta'•rY�r[✓�rrp tryr - � Oae%ri Ruy.0 yyarrl NX 9µrY �.• Y,lu ifttt �%✓ Ar.aa♦f avprvN ✓f J `N9e�nr a'ry aefee rry Nra, M'rM IJ Gripin`iypa�y ybn,vrtra•a• IfirygCMpYrr,fr FIGURE is 810FILTRATION SWALE Cmpnunt rur'acr F o'x sV'Su^.c, t5,e'•e I! .- F1:M cine ,`, - SICK, 15". Section A -A cdcw cna, ft", Fi GURE 2: %/EGETATFD FILTER S1 RIP Various factors were considered in identifying feasible locations for the biofiltration swales. It is preferred to locate biofiltration swales adjacent to paved roads and within the public right-of-way. To be considerate of the historical context of the City, buildings contributing to the historical district were added to the inventory of data. Biofiltration facilities were located away from these buildings to the maximum extent feasible. Where a location is ideal due to site topography, proximity to existing storm sewer and estimated runoff from the water quality storm, biofiltration facilities may be located adjacent to those historical buildings to maximize stormwater treatment benefit (such as on East Washington Avenue). Biofiltration facilities were also located at least 300 feel from wetlands according to City Policy H2.5. Lastly, biofiltration swales were prioritized in subbasins that were 1.5 acres or larger and produced at least 0.1 cubic feet per second of runoff during the water quality storm event. These subbasins are presented as High Priority for Treatment Subbasins in Exhibit 3. The various site constraints and locations of the proposed biofiltration swales are shown on Exhibit 3. Within the CIP 1 Treatment Assessment Area, biofiltration swales are proposed along North First Street, North A Street, East Washington Avenue, and East Pennsylvania Avenue. Within the remainder of the Treatment Assessment Area, biofiltration swales are proposed along North Sixth Street, West Third Street, Second Street, South First Street, and portions of West Nevada Avenue, West Utah Avenue, West Arizona Avenue, Dakota Avenue, and West Montana Avenue_ These biofiltration swales will be shallow and will have overflow risers as well as underdrains that will connect into the existing storm sewer network. For the unsewered areas of the City south of California Avenue, vegetated filter strips may be located adjacent to roadways where compatible with street slopes and adjacent land uses. These would provide runoff treatment benefits that have not yet been quantified or mapped with this study. This is a general recommendation for this area of town or other parts of the City where biofiltration is deemed not viable. 7. Water Quality Benefit The proposed improvements do not require Runoff Treatment (Core Element #5) or Flow Control (Core Element #6) in accordance with the SWMMEW (Ecology, 2019). In addition, this retrofit project is not required to meet the new/redevelopment standards. Ecology has established a procedure to quantify the water quality benefit realized through retrofit projects such as this one (Design Deliverables for Stormwater Projects with Ecology Funding, Ecology, Revised June 2018). Because the size and environmental constraints within the project site could control the size and capacity of a BMP, a baseline is quantified by comparing a ratio of the size of the proposed retrofit BMP to the size of a BMP design to meet new/redevelopment criteria. Once this is determined, the Equivalent New/Redevelopment Area for the retrofit project is determined by multiplying the ratios by the contributing area. As the project objective is to provide stormwater runoff treatment for Total Suspended Solids (TSS) and provide for reduction in other pollutants within the urbanized areas of the City, the selected BMPs provide high runoff treatment and low flow control. Therefore, only the runoff treatment water quality benefit is calculated. The following analysis is an assessment of the Water Quality Benefit proposed by the project. This analysis will be refined with future design efforts. 7.1. Runoff Treatment Comparison The Flow Control Ratio was developed following procedure ERT -1: Analysis of Size of traditional Flow Rate or volume -based Runoff Treatment BMP. RatiOERT-t = n flow rate or volume for proposed retrofit treatment BMP Design flow rate or volume to meet new/ redevelopment criteria if Ratior•RT_1 > 1, then set RatiOERT_, = 1 Design flow rates for the water quality storm were output from the XPSWMM model. Biofiltration swales were sized using this design flow rate and the design parameters from the SWMMEW (Ecology, 2019). These calculations are performed with the aid of an Excel spreadsheet. The resultant calculation is a swale length required to meet new/redevelopment runoff treatment criteria. Design flow rates for the proposed retrofits were back calculated using the available footprint of each proposed swale. The biofiltration swale sizing calculations are included in Appendix C. In some cases, the biofiltration swales will be able to achieve more treatment than needed with a RatioeaT-1 > 1, therefore RatiOERT.1 = 1. The ratios for each biofiltration $wale are shown in Appendix D. 7.2. Equivalent New/Redevelopment Areas The Equivalent New/Redevelopment Areas for the project are summarized in Appendix D. Ten (10) of the biofiltration swales will achieve full stormwater treatment equivalent to a new/redeveloped project and ten (10) of the biofiltration swales will achieve partial stormwater treatment within their respective subbasins. The overall water quality benefit to be realized within the study area is 31 percent. This is quantified by comparing the total calculated Equivalent New/Redevelopment Areas, 46.6 acres, to the Treatment Assessment Area, 152.0 acres. The water quality benefit can be further refined with the advancement of each CIP. 8. Capital Improvement Plan The BMPs are based on the preliminary design calculations. Multiple considerations should be made for design implementation. Site investigations including topographic survey and geotechnical evaluations should be conducted for effective design of each BMP. Public outreach should be organized to gather input and support for project improvements. Final design should include the consideration of sizing for snow storage, selection of site appropriate plantings for the region, and access for operations and maintenance. Engineering and construction administration should be included for effective design and construction of each BMP. The BMPs within the study area are divided into three separate CIPs for project planning purposes: CIP 1, CIP SW -1, and CIP SW -2. CIP 1 includes the biofiltration swales identified within the CIP 1 Treatment Assessment Area. The CIP 1 treatment project will be advanced in detail design after study completion. CIP SW -1 and CIP SW -2 include the remaining biofiltration swales identified in the Treatment Assessment Area. Biofiltration swales in CIP SW -1 and CIP SW -2 are grouped to include a similar quantity of biofiltration Swale area as compared to the CIP 1 treatment project. The estimated construction cost of CIP SW -1 includes Biofiltration B1, B2, C1A, D1, and D2. The estimated construction approximated cost of CIP SW -2 includes Biofiltration B14, B15A, B16A, D4, G2, H4, and H5. CIP SW -1 and CIP SW -2 may be implemented through individual biofiltration Swale design and construction, or in clusters as specific stormwater treatment funding is available and/or incorporated with roadway improvement projects. - LEGEND 5 GTYIMDE STWY WIN _ STOWINATER RETROFIT -%STODY AREA _ j GP i BASIN GPI TREAT w ASSESSMENT AREA LNDERWED EMSTING PIPE SYSTEM PLANNED CI% WERROW PIPE iS...

The Plan recommended the City form a Stormwater Utility and levy a monthly utility rate to fund stormwater operation, maintenance, and a share of capital improvements. In 2016, the Roslyn City Council created a Stormwater Utility to manage and regulate surface and stormwater. (City of Roslyn, 2016) A stormwater utility fund was created, and in 2017 the City began assessing a stormwater fee on properties in the city.
