Drainage improvement projects addressed large storm events and local flooding with little thought for upstream, or environmental impacts. With the passage of the Clean Water Act in 1972, completion of the Nationwide Urban Runoff Program in 1983, and subsequently other federal and state laws, the cumulative effects of smaller storms in developed/urbanized areas were formally recognized as a major contributor to water quality and habitat degradation. Stormwater runoff picks up and carries sediment and pollutants from exposed construction sites and agricultural areas and pollutants from residential, commercial, and industrial developments. Pollutants in stormwater runoff include metals such as lead, cadmium, and copper; oil and grease; pesticides and fertilizers; nutrients; suspended solids; and harmful bacteria. In addition, urbanization increases the amount of impervious surfaces such as rooftops, streets, and parking areas. Impervious surfaces directly relate to an increase in runoff volumes and peak flow rates. The pollutant loads and increased volumes of stormwater runoff result in negative impacts to properties and surface water bodies such as lakes, streams, and wetlands and reduced infiltration to groundwater. Due to regulations required under the Clean Water Act and the listing of anadromous (salmon, trout, char) species under the Endangered Species Act, it has become increasingly important for municipalities to implement stormwater quality and quantity (flow) control measures. The City of Marysville last adopted its Surface Water Comprehensive Plan in 2009. The City population has grown from approximately 25,000 in 2002 to approximately 63,000 today, primarily through annexation. A significant portion of this growth has occurred since the completion of the 2009 Surface Water Comprehensive Plan when the City annexed the majority of its Urban Growth Area (UGA) in December of 2009. PURPOSE The City of Marysville Surface Water Comprehensive Plan (Plan) is a planning document that provides guidance to minimize adverse effects of stormwater runoff on ground and surface water in a manner that complies with federal, state, and local surface water regulations. It identifies water quality and quantity problems associated with stormwater runoff that may affect the environment and community, and provides recommendations for improvements and programs including a financial analysis and implementation schedule. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 2 City of Marysville December 2016 Surface Water Comprehensive Plan Update The Plan identifies specific structural and nonstructural solutions to quantity and water quality problems within the City. Structural solutions include construction of capital projects such as stormwater detention and treatment facilities, infiltration facilities, pipelines, and culverts. Nonstructural solutions include stormwater management facility inspection and maintenance, public education and outreach, water quality monitoring, implementation of best management practices (BMPs), and regulations encouraging vegetation preservation and low impact development. GOALS As additional development and redevelopment occur within the City, the amount of naturally vegetated areas will decrease while the amount of impervious surfaces will increase, leading ultimately to increased peak runoff rates and transport of more pollutants to the City’s streams, wetlands, and rivers. The primary goal of the Marysville Stormwater Comprehensive Plan is to provide guidance to the City Council, staff, and citizens to preserve and protect the water quality and hydrologic regime within the City’s natural and manmade surface and stormwater drainage system, and the major receiving waters, Ebey Slough and the Snohomish River. To this end, the City intends to manage land development and stormwater programs to preserve natural areas, minimize contact with contaminants, mitigate the impacts of increased runoff, enforce the City’s National Pollutant Discharge Elimination System (NPDES) permit conditions and erosion control BMPs on construction sites, and to preserve fish and wildlife habitat. The City’s implementation of the Plan will meet the goals to protect the health, safety, and welfare of the local citizenry and to preserve surface water resources within the City. ---PAGE BREAK--- City of Marysville 3 Surface Water Comprehensive Plan Update December 2016 CHAPTER 2 SERVICE AREA CHARACTERISTICS LOCATION The City of Marysville (City) was officially incorporated in Washington State in 1891 with a population of 350. It is located in Snohomish County, approximately 5 miles north of Everett and directly borders the City of Arlington to the north. The City’s current boundary and Urban Growth Area (UGA) encompass approximately 21 square miles of land. Interstate 5 and State Routes 531, 528, and 539 pass through the City, while State Route 9 provides the border to the east. The Burlington Northern Santa Fe Railroad also runs north/south through the City. Figure 2-1 provides a vicinity map of the area. Marysville is the second largest city in Snohomish County. Per the census conducted in 2010, the population was approximately 60,000, representing 8.4 percent of the total population of Snohomish County. In 2015, the population was estimated to be 65,000. TOPOGRAPHY Marysville lies between the Puget Sound and the Central Cascade Mountains, with Mount Pilchuck being a prominent fixture on the horizon. The south end of the City sits along Ebey Slough just before it discharges into Possession Sound along with Steamboat Slough and the Snohomish River (see Figure 2-2). The elevation within the City gradually slopes north to south along the I-5 corridor from 160 feet in the north end of the City to 5 feet at Ebey slough in the south end. This area is known as the Marysville Trough, which is an alluvial plain that runs through much of the City. The Tulalip Plateau borders the Marysville Trough to the west, and to the east is the Getchell Hill Plateau, reaching a maximum elevation of 465 feet on the eastern border of the Marysville city limits. In the Smokey Point neighborhood, on the north end of the city, the trough continues well beyond the City limits, maintaining fairly flat terrain throughout. DRAINAGE BASINS The City of Marysville is located within the Snohomish River Drainage Basin within Water Resource Inventory Area 7 (WRIA the second largest watershed in the state. The basin encompasses 1,978 square miles west of the Cascade crest. As shown in Figure 2-3, four smaller drainage basins have been delineated around the City’s drainage infrastructure: Quilceda Creek, Allen Creek, King Creek, and Ebey Slough. All four of these basins empty into Ebey Slough, which then joins with the Snohomish River near its drainage point into Possession Sound. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 4 City of Marysville December 2016 Surface Water Comprehensive Plan Update Quilceda Creek Basin encompasses 36.6 square miles, 9.3 square miles of which are located in the City and is the largest basin within the City. It runs north-south on the east side of the City and is predominately located within the Marysville Trough. It generally consists of till and outwash soils. Although outwash soils usually drain well, high groundwater in the winter months creates saturated soil conditions that impedes infiltration, and commonly results in a high rate of surface water runoff. The second largest basin that lies within the Marysville UGA is the Allen Creek Basin. It has an overall area of 10.4 square miles, 7.7 of which are within the UGA boundary. The Allen Creek Basin makes up a large portion of the southeastern part of the City, having most of its area on the Getchell Plateau. The soils in the Allen Basin are very similar to that of the Quilceda Basin and have similar surface water runoff issues caused by high groundwater. The other two basins, Ebey Slough Basin and King Creek Basin, are significantly smaller than the Quilceda and Allen Creek Basins, only making up 1.9 and 2.9 square miles respectively. The Ebey Slough Basin is contained entirely within the Marysville city limits on the south end and sits mostly within the Marysville Trough. The Sunnyside Basin sits atop the Getchell Plateau and extends south from the edge of the Marysville City limits with approximately half the basin contained within the city limits. WATERWAYS AND WATER BODIES The City of Marysville contains many waterways, most of which are within the Quilceda Creek and Allen Creek Basins. These waterways have been manipulated and channelized over the years and are highly susceptible to environmental problems such as pollution, erosion, and flooding. Non-point source pollution from agriculture and urban development have increased the presence of pesticides, animal waste, chemical fertilizers, sediments, heavy metals, detergents, and petroleum. Allen Creek and Quilceda Creek have been placed on Washington State’s 303(d) list for fecal coliform, which requires them to have Total Maximum Daily Load (TMDL) cleanup plans. Low dissolved oxygen levels are also a concern in the summer months and can compromise crucial fish and wildlife habitat. The Quilceda and Allen Creek systems are within the Tulalip Tribes’ usual and accustomed fishing areas. Land use within this these systems is therefore governed by a variety of tribal, state, county, and city governments. SOILS The soils of Snohomish County were surveyed by the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS). The NRCS website indicates 22 soil types within the UGA of Marysville, as shown in Figure 2-4 and Table 2-1. ---PAGE BREAK--- 5 5 5 92 531 531 9 529 9 99 99 531 9 528 67TH AVE NE STATE AVE 172ND ST NE

(SCS) classifies soils, from A to D, according to runoff potential. Type A has low runoff potential and high infiltration rates even when thoroughly wetted, and mostly consists of well to excessively drained sands or gravels. Type B consists of moderately well to well drained soils with moderately fine to moderately coarse texture and moderate infiltration rates when thoroughly wetted. Type C has low infiltration rates when thoroughly wetted with moderately fine to fine textured soils, and often have a layer that impedes downward movement of water. Type D has the highest runoff potential and very low infiltration rates when thoroughly wetted. It consists of clay soils with high swelling potential, soils with a permanent high water table, soils with a claypan or clay layer at or near the surface, and shallow soils over nearly impervious material. The SCS also provides information pertaining to the physical and chemical properties of the soils, including drainage class, which refers to the frequency and duration of wet periods under conditions similar to those under which the soil formed. The northern region of the city predominantly contains low infiltration Type C and D soils. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 6 City of Marysville December 2016 Surface Water Comprehensive Plan Update The central area consists mostly of type A soils and the southeastern area consists mostly of type B soils, both having high to moderate infiltration and lower potential for runoff. POPULATION TRENDS Residential population for the City was estimated by the United States Census to be 60,202 in 2010. Per the City’s 2015 Comprehensive Plan, it is estimated that approximately 65,000 people live within the City. The City Plan also creates a 20-year population growth target which estimates approximately 87,000 people in 2035. This estimate is based upon available land areas and existing zoning classifications within the City and UGA. Census data, proposed new residential units and sensitive areas were factored into the development of the growth rate. Table 2-2 summarizes the historic population estimates based on the U.S. Census as well as the forecasted population estimates from the City’s current Comprehensive Plan. TABLE 2-2 Population Year Population 1980 5,080 1990 10,328 2000 25,315 2010 60,202(1) 2015 65,087(1) 2035 87,800(1) Estimated. ZONING AND LAND USE The population in Marysville grew by approximately 137 percent between the year 2000 and 2010. Land use and zoning play an important role in determining growth patterns and; therefore, in the potential locations of future storm water facilities. Future land use and changing population densities, as directed by applicable zoning ordinances, can significantly impact a system’s ability to provide adequate services to specific areas. Marysville has a combination of residential, commercial, industrial and open space land uses as shown in Figure 2-5. This figure provides a map of future land use for the City as shown in the City’s 2015 Comprehensive Plan. Residential zones make up two thirds of the Marysville UGA, and are positioned in the central and southeastern regions, with a small region in the Lakewood area as well. The open space areas are spread throughout the City, with the largest located in the south end of the City where Jones Creek and Allen Creek discharge into Ebey Slough. ---PAGE BREAK--- 92 531 531 9 529 9 99 99 531 9 528 5 5 5 67TH AVE NE STATE AVE 172ND ST NE 51ST AVE NE GROVE ST 83RD AVE NE 27TH AVE NE SMOKEY POINT BLVD 64TH ST NE 88TH ST NE 108TH ST NE 99TH AVE NE MARINE DR NE FORTY FIVE RD 140TH ST NE 152ND ST NE 3RD AVE NE 4TH ST 100TH ST NE CEDAR AVE 136TH ST NE 71ST AVE NE 23RD AVE NE AIRPORT BLVD 84TH ST NE 116TH ST NE 48TH DR NE 80TH ST NE 10TH ST 60TH ST NE ARMAR RD VE NE 172ND ST NW 44TH ST NE 99TH AVE NE SUNNYSIDE BLVD 4TH ST NE 84TH 51ST AVE NE 19TH AVE NE 132ND ST NE 51ST AVE NE 1ST ST POSSESSION SOUND Lakewood Region Smokey Point Region Hayho Creek Quilceda Creek Allen Creek LAKE CASSIDY E b e y Slo u gh Stea m bo a t Sl ough Snohom ish River Union Sl ou g h Allen Creek Q uilced a Cree k Hayho Creek J ones Cree k Po rtage C ree k H u l be r t C r e ek Mun so n C ree k W est Fork Quilceda Creek Wi e se r C r e e k Littl e C oho Ed g e com b Cree k Mi d dl e Fork Quilce d a Cre e k Quilced a C r eek Ed gec o m b Creek Midd le For k Quil ceda Cr e ek Quilceda Creek Jones Creek King Creek Sturgeon Creek Olaf Strad Creek M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 2-5.mxd Zoning Business Park Community Business Downtown Commercial General Commercial General Industrial Light Industrial Mixed Use Neighborhood Business Open Public-Institutional R12 Multi-Family Low R18 Multi-Family Medium R28 Multi-Family High R4-8 Single Family High R4.5 Single Family Medium R6-18 Multi-Family Low R6.5 Single Family High R8 Single Family High Small Lot Recreation Marysville City Limits Urban Growth Boundary Streams Water Bodies 0 5,000 10,000 15,000 FeetÜ FUTURE LAND USE MAP FIGURE 2-5 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 7 Surface Water Comprehensive Plan Update December 2016 The vast majority of the commercial and industrial property is on the west side of the City along I-5. New commercial and industrial development is occurring in the Lakewood and Smokey Point neighborhoods in the north, and in the Downtown area, located in the south end of the City. The development in the Smokey Point region has potential to have significant stormwater implications, as much of that land is currently being used for agriculture, but is zoned light industrial and could soon experience a significant increase in impervious surface. This change in impervious surface will require extensive storm water management to mitigate flooding and pollution of surface waters in the upper reaches of the Quilceda Creek Basin.

These areas require special considerations and protections in order to preserve the functions that benefit the City and its residents, and to protect public health and safety from potential hazards. The aquifers that lie within the boundaries of the Marysville UGA do not fit the criteria of a critical area as defined by the Growth Management Act (RCW 36.70A.060) due to the fact that they are not used for potable water; however, they are discussed below because they play a significant role in stormwater drainage issues and are important in maintaining stream base flow, which impacts fish and wildlife habitat. WETLANDS As defined by MMC 22A.020.240 wetlands are areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 9 Surface Water Comprehensive Plan Update December 2016 under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. This includes swamps, marshes, bogs, and similar areas, but excludes artificial wetland sites such as irrigation and drainage ditches, grass-lined swales, canals, detention facilities, farm ponds, landscape amenities, or any wetland unintentionally created by road construction after July 1, 1990. Artificial wetlands created intentionally for mitigation purposes are included in this definition and are protected under the critical areas ordinance. Wetlands perform valuable functions within the ecosystem. Clearing of vegetation, grading, filling, draining, and other activities associated with land development may decrease the ability of the riparian zone to provide drainage, stabilize stream banks, provide wildlife habitat, and filter pollutants from runoff. Wetlands receiving surface water from surrounding areas can filter entering pollutants by a combination of physical, chemical, and biological processes. Wetlands also play a major role in flood control. During flooding, rivers and streams overflow their banks and spread out across the flood plain. Wetlands attenuate the peak flows from storm events by storing water during wet periods and discharging this stored water later during drier periods. Wetlands also provide habitat and a source of food for fish and wildlife. Seventy-five percent of Western Washington’s wildlife species use wetlands or riparian zones during some portion of their life cycle, and many species solely inhabit wetland areas. Washington State Department of Ecology (Ecology) rates wetlands into four different categories (Categories I, II, III, and IV). These categories are based on the wetland’s sensitivity to disturbance, rarity, functions they provide, and whether or not they are replaceable; Category I being the most crucial to protect. Within the UGA, Marysville has a total of 434 acres of known wetland area; 142 acres of Category I, 134 acres of Category II, 141 acres of Category III, and 18 acres of Category IV. Figure 2-6 depicts the delineation of all four wetland categories as provided by the City’s GIS data, as reported from limited scope studies and from development. MMC 22E.010.100 establishes minimum targets for buffer widths around wetland boundaries based on the sensitivity and category of the wetland and the intensity of human activity proposed to be conducted. Table 2-5 provides these minimum regulatory buffer area requirements. Exemptions and exceptions to wetland protections and buffer widths can be found in MMC 22E.010 ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 10 City of Marysville December 2016 Surface Water Comprehensive Plan Update TABLE 2-5 Wetland Buffer Widths Wetland Category Buffer Width Category I 125 feet Ebey Slough 100 feet Ebey Slough Exception: North and south shore between the western city limits, at approximately I-5, and 47th Avenue NE 25 feet Category II 100 feet Category III 75 feet Category IV 35 feet AQUIFER RECHARGE AREAS Marysville relies on an aquifer for potable drinking water only in the Lake Goodwin area. Surrounding aquifers within the City’s UGA mainly provide discharge into streams, supporting year round flow and crucial fish and wildlife habitat. The Marysville Trough Aquifer and the Getchell-Snohomish Aquifer are both partially located within the Marysville UGA and benefit from stream and wetland protections under the Critical Area Ordinance. The Marysville Trough Aquifer and the Getchell-Snohomish Aquifer also have an influence on Geologic Hazard Areas and storm water runoff. In the winter months, the ground water levels in these aquifers often reach ground level causing overland flow that can carry pollutants directly into surface waters, and cause flooding in some areas. Additionally, the saturated soils create favorable conditions for landslides to occur in areas with steep slopes and can increase erosion, reducing the suitable habitat for salmon. FISH AND WILDLIFE HABITAT AREAS Most of the City’s wildlife habitat exists in areas that have retained second growth forest or heavy vegetation. This includes the healthy salmonid spawning and rearing habitat at the headwaters of many of the tributaries to Quilceda Creek and Allen Creek. Healthy Coho and Chum salmon spawning and rearing habitat can be found in many parts of the Quilceda Creek system along with resident cutthroat trout habitat in the headwaters of Edgecomb Creek. Fish habitat in agricultural areas has declined as buffers are not common in agricultural fields. Much of the spawning habitat has diminished in the Allen Creek system due to erosion causing stream beds to fill in with mud and silt, canary reed grass growing in streambeds/channelized sections of the system, and eliminated wetlands. Chinook salmon, steelhead, and rainbow trout also utilize the streams in the Quilceda and Allen Creek watersheds but to a lesser degree than the previously mentioned species. ---PAGE BREAK--- 92 531 531 9 529 9 99 99 531 9 528 5 5 5 67TH AVE NE STATE AVE 172ND ST NE 51ST AVE NE GROVE ST 83RD AVE NE 27TH AVE NE SMOKEY POINT BLVD 64TH ST NE 88TH ST NE 108TH ST NE 99TH AVE NE MARINE DR NE FORTY FIVE RD 140TH ST NE 152ND ST NE 3RD AVE NE 4TH ST 100TH ST NE CEDAR AVE 136TH ST NE 71ST AVE NE 23RD AVE NE AIRPORT BLVD 84TH ST NE 116TH ST NE 48TH DR NE 80TH ST NE 10TH ST 60TH ST NE ARMAR RD VE NE 172ND ST NW 44TH ST NE 99TH AVE NE SUNNYSIDE BLVD 4TH ST NE 84TH 51ST AVE NE 19TH AVE NE 132ND ST NE 51ST AVE NE 1ST ST POSSESSION SOUND Hayho Creek Quilceda Creek Allen Creek E b e y Slo u gh Stea m bo a t Sl ough Snohom ish River Union Sl ou g h Allen Creek Q u ilc e da Cr e ek Hayho Creek J o n es C r eek Po rtage C ree k H u l be r t C r e ek Mun so n C ree k W e s t Fork Quilceda Creek Wi ese r C r e ek Little C oho Ed g e com b Cree k Mi d dl e Fork Quilce d a Cre e k Quilced a C r eek Middle F ork Q u i l ced a Creek M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 2-6.mxd Wetlands Category 1 Category 2 Category 3 Category 4 Water Bodies Wetland Buffers Basin Name Allen Creek Basin Ebey Slough Basin North Ebey Slough Basin South King Creek Basin Quilceda Creek Basin Marysville City Limits Urban Growth Boundary Streams 0 5,000 10,000 15,000 Feet Ü WETLANDS MAP FIGURE 2-6 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE Note: Wetlands shown are reflective of what information the City has obtained to date.

The following categories are defined by MMC 22E.010.220 and are shown in Figure 2-7. Type S Stream: Those streams, within their ordinary high water mark, as inventoried as “shorelines of the state” under Chapter 90.58 RCW and the rules promulgated pursuant thereto. Type F Stream: Those stream segments within the ordinary high water mark that are not Type S streams, and which are demonstrated or provisionally presumed to be used by salmonid fish. Stream segments which have a width of two feet or greater at the ordinary high water mark and have a gradient of 16 percent or less for basins less than or equal to 50 acres in size, or have a gradient of 20 percent or less for basins greater than 50 acres in size, are provisionally presumed to be used by salmonid fish. Type Np Stream: Those stream segments within the ordinary high water mark that are perennial and are not Type S or Type F streams. However, for the purpose of classification, Type Np streams include intermittent dry portions of the channel below the uppermost point of perennial flow. Type Ns Stream: Those stream segments within the ordinary high water mark that are not Type S, Type F, or Type Np streams. These include seasonal streams in which surface flow is not present for at least some portion of a year of normal rainfall that are not located from any Type Np stream segment. Table 2-6 provides those categories along with their associated protected buffer widths.

Figure 2-8 is provided to give a general guide to where potential hazard areas are located within the City. Field investigation and analysis is required to confirm the presence or absence of these areas before development can occur. Generally, these areas warrant additional engineering investigation to assess the level of hazard and would typically require setbacks from these areas, special construction techniques, or outright prohibition with respect to land disturbance and development. The most prominent Geological hazard area within the Marysville UGA is in the 100-year flood zone of Ebey Slough. This area is characterized to have moderate to high susceptibility to soil liquefaction during a seismic event. High susceptibility for soil liquefaction is also found along portions of Quilceda Creek and Allen Creek. Soil liquefaction may occur in areas that have saturated silt and/or sand soils when shaking due to seismic activity causes the soil to act as a liquid, losing its ability to support structures. Landslide hazard areas have been identified in many areas of the Getchell Plateau including the banks along Munson Creek, and along the banks of Quilceda Creek and Allen Creek. A combination of steep slopes ranging from 25 percent to 75 percent, soft soils, and groundwater seepage create favorable conditions for landsides to occur. These areas, along with other tributaries to Quilceda and Allen Creeks, are also prone to erosion. The previously mentioned geologic conditions combined with human activities such as land use change/development have led to unstable slopes and increased stream flow, causing significant erosion in some areas. STORMWATER UTILITY SERVICES The City of Marysville has had a surface water management (SWM) program since 1991. Until 2007, the surface water utility fee was collected by Snohomish County in connection to property taxes and then remitted to the City of Marysville. In January 2007, the City’s Public Works Department took over administration of the SWM utility and continues to manage the program. Fees collected by the SWM utility are for the purpose of operating public stormwater facilities to help reduce flooding and drainage problems, improve water quality, and meet regulatory requirements. Operation of this utility includes the ability to finance, construct, develop, improve, and maintain the City’s stormwater facilities. The facilities consist of approximately 6,225 lineal feet of detention pipe, 185 miles of storm lines, 11,914 catch basins, 346 infiltration/detention ponds, and multiple outfalls into area receiving waters. ---PAGE BREAK--- 5 5 5 92 531 531 9 529 9 99 99 531 9 528 67TH AVE NE STATE AVE 172ND ST NE 51ST AVE NE GROVE ST 83RD AVE NE 27TH AVE NE SMOKEY POINT BLVD 64TH ST NE 88TH ST NE 108TH ST NE 99TH AVE NE MARINE DR NE FORTY FIVE RD 140TH ST NE 152ND ST NE 3RD AVE NE 4TH ST 100TH ST NE CEDAR AVE 136TH ST NE 71ST AVE NE 23RD AVE NE AIRPORT BLVD 84TH ST NE 116TH ST NE 48TH DR NE 80TH ST NE 60TH ST NE ARMAR RD 172ND ST NW 44TH ST NE 99TH AVE NE SUNNYSIDE BLVD 84TH ST NE 51ST AVE NE 19TH AVE NE 132ND ST NE 51ST AVE NE 1ST ST POSSESSION SOUND LAKE CASSIDY Hayho Creek Quilceda Creek Allen Creek E b e y Slo u gh Stea m bo a t Sl ough Snohom ish River Union Sl ou g h Allen Creek Quilceda Creek Hayho Creek Edgecomb Creek Portage Creek Munson Creek Jones Creek Sturgeon Creek West Fork Quilceda Creek Olaf Strad Creek King Creek Little Coho Middle Fork Quilceda Creek Catherine Creek Quilceda Creek M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 2-7.mxd Stream Class S F NP NS Unclassified Basins Allen Creek Basin Ebey Slough Basin North Ebey Slough Basin South King Creek Basin Quilceda Creek Basin Stream Buffers Marysville City Limits Urban Growth Boundary Streets Water Bodies 0 5,000 10,000 15,000 Feet Ü STREAM CLASSES MAPS FIGURE 2-7 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE Note: Stream classes shown have not been approved by the Wa.

The analysis includes review of previous reports completed by Snohomish County and the City of Marysville, hydraulic and hydrologic modeling of areas identified by City staff, and feasibility studies for water quality improvements to address discharge into compromised waterways. EXISTING STORMWATER MANAGEMENT SYSTEM The City’s existing stormwater management system consists of a combination of open ditches, pipes, catch basins, culverts, detention ponds, detention vaults, infiltration ponds, infiltration vaults, bioswales, filter strips, raingardens, and water quality treatment ponds. A base map showing drainage facilities within the City is shown in Figure 3-1. A large fold-out map is also included in Appendix A. REFERENCED REPORTS The following reports were reviewed during the analysis of the City’s stormwater management system:  Quilceda Creek Drainage Needs Report, DNR No. 1, December 2002, Snohomish County Public Works Department Surface Water Management Division  Allen Creek Drainage Needs Report, DNR No. 8, December 2002, Snohomish County Public Works Department Surface Water Management Division  City of Marysville Surface Water Comprehensive Plan Update, February 2009, Otak, Inc.  North Marysville Edgecomb Creek Relocation Feasibility Study, July 2009, Otak, Inc. WATER QUALITY While water quality is an important part of stormwater management, this Plan focuses mostly on conveyance infrastructure. Marysville holds a Phase II National Pollutant Discharge Elimination System (NPDES) Stormwater Permit, which requires annual reporting of stormwater monitoring and assessment. Further information about ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 14 City of Marysville December 2016 Surface Water Comprehensive Plan Update Marysville’s water quality program may be found in the City of Marysville’s Stormwater Management Program Plan (SWMP) available on the City’s website. CITY IDENTIFIED STORMWATER CONVEYANCE PROBLEMS City employee comments and public complaints were reviewed in order to identify any issues that have occurred since the 2009 Surface Water Comprehensive Plan (2009 Comp Plan). A field investigation of specific problem areas was conducted to identify new projects. The City also provided an account of projects identified in previous plans that still need to be addressed. Many of these projects required reevaluation to ensure compliance with the Washington Department of Fish and Wildlife 2013 Water Crossing Guidelines (WDFW 2013 Guidelines) Modeling. Hydrologic and hydraulic models of the City’s stormwater system and drainage basins were developed by Snohomish County while conducting the 2002 Drainage Needs Report No. 1 for the Quilceda Creek Basin (2002 DNR No. 1) and the 2002 Drainage Needs Report No. 8 for the Allen Creek Basin (2002 DNR No. Updated versions of the models were used in the 2009 Comp Plan, and additional modeling was performed for the current Plan. HYDROLOGIC MODEL Hydrologic analysis addresses the movement of rainfall to the conveyance system. The purpose of a hydrologic model is to predict the flow of stormwater runoff into the system. Hydrologic models were developed by Snohomish County for the 2002 DNRs using the Hydrologic Simulation Program- FORTRAN (HSPF), version 12.0, developed by the United States Environmental Protection Agency. The HSPF model simulates rainfall- runoff from pervious and impervious land surfaces, soil moisture dynamics, and hydrologic routing on a continuous basis, and uses historical rainfall records to generate a long-term series of stormwater discharges. The long-term flow record is necessary for the evaluation of detention facilities and other volume dependent features within the conveyance system, and is important in the Puget Sound region for accurately evaluating flooding, where flooding is often caused by a series of back-to-back storm events rather that an isolated rainfall event. HYDRAULIC MODEL Hydraulic analysis addresses the movement of runoff through the conveyance system. The purpose of a hydraulic model is to evaluate the capacity of features within the conveyance system, such as pipes, culverts, and open channels. Hydraulic modeling for the stream systems and tributary open channels within the Marysville UGA was developed by Snohomish County for the 2002 DNRs using the Hydrologic Engineering Center River Analysis System (HEC-RAS) model. HEC-RAS is a backwater model designed to simulate the hydraulics of open channel systems, and can simulate flow through culverts and other features commonly found throughout a developed area. ---PAGE BREAK--- 92 531 531 9 529 9 99 99 531 9 528 5 5 5 67TH AVE NE STATE AVE 172ND ST NE 51ST AVE NE GROVE ST 83RD AVE NE 27TH AVE NE SMOKEY POINT BLVD 64TH ST NE 88TH ST NE 108TH ST NE 99TH AVE NE MARINE DR NE FORTY FIVE RD 140TH ST NE 152ND ST NE 3RD AVE NE 4TH ST 100TH ST NE CEDAR AVE 136TH ST NE 71ST AVE NE 23RD AVE NE AIRPORT BLVD 84TH ST NE 116TH ST NE 48TH DR NE 80TH ST NE 60TH ST NE ARMAR RD 172ND ST NW 44TH ST NE 99TH AVE NE SUNNYSIDE BLVD 84TH ST NE 51ST AVE NE 19TH AVE NE 132ND ST NE 51ST AVE NE 1ST ST POSSESSION SOUND LAKE CASSIDY Hayho Creek Quilceda Creek Allen Creek E b e y Sloug h Stea mb oat Slou g h Union Slou gh Snohom ish River R Allen Creek Hayho Creek J o n es C r e e k Po rtage Cre e k W e s t Fork Quilceda Creek Little C oho E dgecomb C r ee k Quilced a C r eek Ed g e comb C r e ek Middle F ork Q u i l ced a Creek M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 3-1.mxd Basin Name Allen Creek Basin Ebey Slough Basin North Ebey Slough Basin South King Creek Basin Quilceda Creek Basin Storm Facilities Detention Pond Infiltration Pond Water Bodies Stormlines Streams Marysville City Limits Urban Growth Boundary 0 3,000 6,000 9,000 Feet Ü EXISTING STORMWATER FACILITIES FIGURE 3-1 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 15 Surface Water Comprehensive Plan Update December 2016 For a portion of the Sunnyside neighborhood within the Allen Creek Basin, a model was developed by Snohomish County using the Extran portion of the U.S. Environmental Protection Agency’s Stormwater Management Model (SWMM). For this model, storms were identified that had peak flows at or near the 2-year, 10-year, and 25-year return frequency peaks, and of these, three 3-day events were selected to account for antecedent rainfall. In the 2009 Comp Plan, a later and proprietary version of this same modeling software owned by XP Solutions) was used to simulate conveyance systems and detention ponds within the North Marysville region. XP Solutions later developed a newer version of called XPStorm, which was used for this current Plan to model the designs for culverts subject to the WDFW 2013 Guidelines, and to evaluate flooding issues. DRAINAGE BASINS The City’s stormwater infrastructure is divided into four drainage basins: Quilceda Creek, Allen Creek, King Creek, and Ebey Slough. Table 3-1 shows the total area of each basin, as well as the area within the Marysville UGA. These basins are described in detail in Chapter 2. TABLE 3-1 Drainage Basin Summary Basin Total Area (mi 2) Area within UGA (mi 2) Quilceda Creek 36.6 9.3 Allen Creek 10.4 7.7 King Creek 2.9 1.6 Ebey Slough 1.9 1.9 IDENTIFIED DEFICIENCIES After review of deficiencies identified by the past Snohomish County Plans, staff comments and public complaints, the following areas have been identified as current deficiencies. These areas are named and organized by drainage basin, and described below. The two letters in the identification number of the problem area represent the initials of the drainage basin QC1 = Quilceda Creek Area No. The former name of the projects from the 2009 Comp Plan is given in parentheses. The new identification numbers also correspond to the number assigned to the recommended Capital Improvement Plan (CIP) project for each individual project. Further discussion regarding solutions or recommended CIPs for these problem areas is described in Chapter 4 (Capital Improvement Plan). ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 16 City of Marysville December 2016 Surface Water Comprehensive Plan Update QUILCEDA CREEK BASIN Several key problem areas were identified within the Quilceda Creek Basin. These areas include flooding issues, fish passage barriers, ecological deficiencies, aging infrastructure, and stormwater management. Figures 3-2 and 3-3 locate the Quilceda Creek areas described herein. QC1 Stormwater Pipe Damage at Edward Springs Reservoir City staff identified a 36-inch CMP drainage pipe that runs along the northeast side of the Edward Springs Reservoir (SD-LINE-15039) as having significant rust damage due to age. The recommended solution for this issue is to replace 395 LF of CMP pipe with new corrugated polyethylene (CPEP) pipe. QC2 (Formerly MQ-HH-19) Irrigation Ditch Accessible to Fish Upstream of 160th Street NE Upstream of 160th Street NE, Hayho Creek and its tributaries are subject to water withdrawals for irrigation. Waterways used for irrigation require a fish screen of the withdrawal to prevent fish from being drawn into the diversion channels. Installing a fish screen at this location will protect fish by blocking off approximately 1 mile of diversion channels to fish access. This was proposed in the 2009 Comp Plan, and originated from city staff recommendations. QC3 (Formerly MQ-EC-03, MQ-EC-05) Undersized Field Access Culvert along Edgecomb Creek Two privately owned undersized 30-inch field access culverts along Edgecomb Creek were identified by the 2002 DNR No.1 (IDs of SD-CV-167 and SD-CV-168). These were also identified as Level A barriers to fish passage. The HEC-RAS model developed for the previous report determined that the field access roads would be overtopped at the 2- year frequency for existing and future land use conditions. A reevaluation of these culverts was conducted for current fish passage standards. The results showed that these culverts are a velocity barrier for fish passage. The recommended solution for this issue is to replace both 30-inch culverts with two 16-foot span reinforced concrete box culverts. Culverts should be countersunk 30 percent and should be filled with gravel and sediment to comply with WDFW 2013 Guidelines. QC4A (Formerly MQ-HH-16) Hayho Creek Channel Mitigation (North Marysville Master Drainage Plan) The North Marysville Edgecomb Creek Relocation Feasibility Study was conducted in 2009 to investigate mitigating impacts of high-density development in the Smokey Point Region. The Hayho Creek drainage basin is one of two basins present in the study area, and was evaluated for improvements to allow for development while improving aquatic ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 17 Surface Water Comprehensive Plan Update December 2016 resource function. Proposed improvements for this area include realigning the headwaters of Hayho Creek through existing wetlands. QC4B (Formerly MQ-HH-32) Conveyance for Regional Detention Pond 2 The North Marysville Master Drainage Plan describes the need for installing what is currently known as Regional Pond 2 which was constructed in 2015. This pond, in conjunction with Pond 1 (built in 2004) allows for mitigation of impacts from high- density development in the Smokey Point Region. In general, Ponds 1 and 2 were designed to provide flow control and enhanced water quality treatment for 204.8 acres. Assumed land use north of the ponds includes commercial or light industrial development with 85 percent maximum impervious area. Of these 204 acres, 44.52 acres are anticipated to come from the west side of Smokey Pt. Blvd., north of 152nd Street NE. The remaining 160.31 acres would come from the east side of Smokey Pt. Blvd., north of 152nd Street NE and west of Hayho Creek. As part of the regional pond construction, 1,200 LF of 42-inch conveyance pipe and 191 LF of a 58-inch by 36-inch arched pipe was installed between the ponds and 152nd Street NE. However, additional conveyance will be necessary as development occurs within the collection basin for the regional ponds. Proposed conveyance for this area includes construction of 4,440 LF of 42-inch mainline conveyance pipe which will be used to serve future commercial or industrial areas. QC4C (Formerly MQ-HH-32) Hayho Creek Regional Detention Pond 3 Regional Ponds 1 and 2 are intended to collect runoff west of Hayho Creek. Due to topography and the existence of Hayho Creek, it is infeasible to convey runoff east of Hayho Creek into the regional ponds. Therefore, a third regional pond is recommended to collect runoff from a small area east of Hayho creek, north of 152nd Street NE. With an estimated size of 3.5 acres, Regional Pond 3 is anticipated to be smaller than Ponds 1 and 2. QC5A (Formerly MQ-EC-13) Edgecomb Creek Channel Mitigation (North Marysville Master Drainage Plan) The North Marysville Edgecomb Creek Relocation Feasibility Study was conducted in 2009 to investigate impacts of high-density development in the Smokey Point Region. The development of this area would require the filling of remaining wetlands in the North Marysville Planning area, and the relocation of Edgecomb Creek. The study found that realigning Edgecomb Creek to the west side of the Burlington Northern Santa Fe Railroad would allow for improved function of the waterway and floodplain, while minimizing impacts to other waterways in the region. It would provide 64 acres of forested buffer along the realigned creek, create 29 acres of total wetland within the floodplain corridor, and provide adequate capacity within the constructed floodplain for the 100-year flood. This alignment requires minimal water crossings. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 18 City of Marysville December 2016 Surface Water Comprehensive Plan Update QC5B (Formerly MQ-EC-13) Edgecomb Creek Conveyance (North Marysville Master Drainage Plan) In conjunction with realigning Edgecomb Creek, as development occurs, stormwater conveyance will be necessary to carry runoff away from developed sites located north of 152nd Street NE and east of 51st Avenue NE. To mitigate the need for onsite detention and treatment, a regional pond could be installed south of where the development is anticipated to occur (see QC5C below). The City could work with developers in providing a mainline conveyance trunk to this regional pond. QC5C (Formerly MQ-EC-13) Edgecomb Creek Channel Mitigation (North Marysville Master Drainage Plan) To mitigate the need for individual onsite detention and water quality treatment facilities, a 20-acre regional detention/treatment facility could be located at the south end of the Edgecomb study area, east of 51st Avenue NE and adjacent to the BNSF railway. It would serve commercial/industrial property located north of the pond and adjacent to or just east of 51st Avenue NE. QC6 (Formerly MQ-EC-01) Undersized Culvert along Edgecomb Creek at 152nd Street NE The 36-inch culvert conveying water beneath 152nd Street NE along Edgecomb Creek (SD-CV-147) was identified by the 2002 DNR No. 1 as undersized, and as a Level A barrier to fish passage. The HEC-RAS model developed for the previous report determined that 152nd Street would be overtopped at the 25-year frequency for existing land use conditions and the 10-year frequency for future land use conditions. A reevaluation of the culvert was conducted for current fish passage standards, where it was determined to be a velocity barrier for fish passage. The recommended solution for this issue is to replace the existing 36-inch culvert with a 17-foot span reinforced concrete box culvert. The culvert should be countersunk 30 percent and should be filled with gravel and sediment to comply with WDFW 2013 Guidelines. QC7 (Formerly MQ-MQ-07) Undersized Culvert along Olaf Strad Creek at 152nd Street NE The 36-inch culvert conveying water beneath 152nd Street NE along Olaf Strad Creek (SD-CV-31) was identified in the 2009 Comp Plan as undersized, and as a potential barrier to fish passage. A reevaluation of the culvert was conducted for current fish passage standards, where it was determined to be a velocity barrier for fish passage. The recommended solution for this issue is to replace the existing 36-inch culvert with a 15-foot span reinforced concrete box culvert. The culvert should be countersunk 30 percent and should be filled with gravel and sediment to comply with WDFW 2013 Guidelines. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 19 Surface Water Comprehensive Plan Update December 2016 QC8 (Formerly MQ-MQ-04) Undersized Culvert and Diminished Habitat along Quilceda Creek at Strawberry Fields Trail The 36-inch culvert conveying water beneath the Strawberry Fields Trail along Middle Fork Quilceda Creek (SD-CV-3407) was identified by public complaints to have significant flooding issues. Additionally, it was identified in the 2002 DNR No. 1 to be a velocity barrier for fish passage. A reevaluation of the culvert was conducted for current fish passage standards, and was determined to be a velocity barrier for fish passage. Snohomish County also found the reaches of Middle Fork Quilceda Creek upstream and of the culvert to have insufficient habitat. This was due to a lack of adequate large woody debris (LWD) and riparian recruitment. The recommended solution for this issue is to replace the existing 36-inch culvert with a 19-foot span reinforced concrete box culvert. The culvert should be countersunk 30 percent and should be filled with gravel and sediment to comply with WDFW 2013 Guidelines. Native riparian vegetation and LWD should also be installed along 1,750 linear feet of the existing channel to improve fish habitat. QC9 (Formerly MQ-HH-09) Flooding of 43rd Avenue and Emerald Hills Estates The 2009 Comp Plan found that beaver dams in Hayho Creek cause periodic flooding of 43rd Avenue NE and the adjacent retirement community. The recommended solution for this problem is to install a berm on the side of the 24-inch culvert beneath 43rd Avenue (SD-CV-52), and excavate the ditch on the northwest side of the berm to allow collection of street runoff and backwatering from Hayho Creek. QC10 (Formerly MQ-HH-38) Channel Erosion on Hayho Creek between the Burlington Northern Santa Fe Railroad and 47th Drive NE The 2009 Comp Plan found the reach of Hayho Creek between the Burlington Northern Santa Fe Railroad (BNSF) and 47th Drive NE to be incising and to have significant bank erosion. This is creating a backwater issue that is causing flooding of 136th Street NE at 45th Avenue. The recommended solution to this issue is to stabilize the reach by regrading 850 linear feet of channel. Additionally, large woody debris and native riparian vegetation should be installed along both streambanks. QC10A Flooding of 136th Street NE at 45th Avenue NE Significant flooding has been observed on the north side of 136th Street NE at 45th Avenue NE during intense or prolonged rain events. The flood water is generated from a ditch system that runs along 136th Street NE, but is thought to be due to a backwater issue in Hayho Creek on the east side of 45th Avenue NE. This backwater issue is created in a reach located between the BNSF RR and 47th Drive NE that has diminished capacity due to erosion. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 20 City of Marysville December 2016 Surface Water Comprehensive Plan Update The ditch system along 136th Street NE, its confluence with Hayho Creek, and the stretch of Hayho Creek between 136th and the BNSF RR were modeled in XPSTORM to examine alternatives for preventing the flooding on 136th Street NE. The model used the Santa Barbara Urban Hydrograph method (SBUH) to simulate runoff within the conveyance system. Basin areas were estimated to produce peak flows for the Type 1A storm that matched the flows reported for the 100-year storm event in the 2002 DNR No. 8. The model confirmed that the flooding was due to a backwater issue from Hayho Creek, and that approximately 51,000 cubic feet of runoff along the north side of 136th Street NE would need to be stored to prevent overtopping of the road if the backwater issue caused south of the BNSF culverts was not resolved. The model also showed a capacity issue upstream where a 15-inch culvert between two sections of ditch along 136th Street NE has a reverse slope. While fixing the erosion issue within Hayho Creek is the optimum solution to this flooding problem, an alternative, more economical solution can be installed to prevent the flooding of 136th Street NE until funds are available to perform the necessary repairs. The recommended alternative solution for this issue is to install a storage pond along 136th Street NE at 45th Avenue NE, regrade the section of ditch located approximately 450 feet west of 45th Avenue NE, and replace the 15-inch culvert just upstream from the regraded ditch. This would allow temporary storage of the runoff until the water level recedes. QC11 (Formerly WQ-WQ-08) Undersized Culvert along a Tributary to West Fork Quilceda Creek at 104th Street NE The 4-foot box culvert conveying water beneath 104th Street NE along Lower West Fork Quilceda Creek (SD-CV-42) was identified in the 2009 Comp Plan as undersized, and as a potential barrier to fish passage. It was also noted that beaver dams just from the culvert were contributing to flooding, and had caused the culvert to become clogged with silt. In 2010, emergency maintenance was conducted, which resulted in the beaver dams being removed, and the culvert being cleaned out. A 24-inch culvert was also installed above the ordinary high water mark to reduce flooding. A reevaluation of the culvert was conducted for current fish passage standards, and the existing configuration was determined to be a velocity barrier for fish passage. The recommended solution for this issue is to replace the existing 4-foot box culvert with a 50-foot prefabricated bridge along 104th Street to improve fish passage. QC12 (Formerly WQ-WQ-09) Undersized Culvert along a Tributary to West Fork Quilceda Creek at 103rd Street NE The 24-inch culvert conveying water beneath 103rd Street NE along Lower West Fork Quilceda Creek (SD-CV-43) was identified in the 2009 Comp Plan as undersized, and as a potential barrier to fish passage. A reevaluation of the culvert was conducted for current standards, where it was determined to be a velocity barrier for fish passage. The ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 21 Surface Water Comprehensive Plan Update December 2016 recommended solution for this issue is to replace the existing 24-inch culvert with a 50- foot prefabricated bridge along 103rd Street to improve corridor and fish passage. QC13 (Formerly MQ-QC-09) Undersized Culvert along Quilceda Creek at State Avenue The two 6-foot box culverts conveying water beneath State Avenue NE along Quilceda Creek (SD-CV-30) were identified in the 2002 DNR No.1 to be a velocity barrier for fish passage. A reevaluation of the culvert was conducted for current standards, where it was determined to be a velocity barrier for fish passage. The recommended solution for this issue is to remove the existing culverts and install a 175-foot precast bridge along State Avenue to address corridor and fish passage concerns. QC14 (Formerly MQ-QC-12) Undersized Culvert along Quilceda Creek at BNSF Railroad The 6-foot box culvert conveying water beneath the Burlington Northern Santa Fe Railroad along Quilceda Creek (SD-CV-29) was identified in the 2002 DNR No. 1 to be a velocity barrier for fish passage. A reevaluation of the culvert was conducted for current standards, where it was determined to be a velocity barrier for fish passage. A possible solution for this issue is to remove the existing culvert and to install a 22-foot- diameter, 10-gauge tunnel liner plate. The tunnel liner plate provides a corrugated pipe with continuous circumferential corrugations which provide high strength and stiffness. The tunnel should be countersunk 30 percent and should be filled with gravel and sediment to comply with WDFW 2013 Guidelines. Although this issue is within the Marysville city limits, it is within BNSF right-of-way; and therefore, it is the responsibility of BNSF to replace this culvert. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 22 City of Marysville December 2016 Surface Water Comprehensive Plan Update Page Intentionally Left Blank ---PAGE BREAK--- 531 99 99 531 City of Arlington Hayho Creek E dgecomb M id dle Fork Quilc eda Cr e e k Middle F ork Q QC1 QC7 QC2 QC9 QC3 QC3 QC8 QC6 QC5C QC5B QC4B QC4C QC10 QC4A QC5A QC10A SB I5 NE NB I5 NE 172ND ST NE 67TH AVE NE 51ST AVE NE FORTY FIVE RD 140TH ST NE SMOKEY POINT BLVD 152ND ST NE STATE AVE 34TH AVE NE 136TH ST NE 3RD AVE NE 132ND ST NE 23RD AVE NE AIRPORT BLVD 19TH AVE NE 140TH ST NW 19TH DR NE 156TH ST NE M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 3-2.mxd Identified Deficiency Allen Creek Basin Quilceda Creek Basin Water Bodies Parcels Urban Growth Boundary Marysville City Limits Streams BNSF Railroad 0 5,000 10,000 15,000 Feet Ü IDENTIFIED DEFICIENCIES QUILCEDA CREEK BASIN NORTH FIGURE 3-2 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE QC9: Flooding of 43rd Ave at Emerald Hills Estates Issue: Capacity/Biological Potential Solution: Install berm and excavate ditch QC1: Stormwater Pipe Damage at Edward Springs Reservoir Issue: Damage Potential Solution: Replace 395 LF of 36" CMP pipe with 36" CPEP pipe QC4A: Hayho Creek Channel Mitigation (North Marysville Master Drainage Plan) Issue: Mitigation/Habitat Potential Solution: Realign headwaters of Hayho Creek QC2: Irrigation Ditch Accessible to Fish upstream of 160th St NE Issue: Biological Potential Solution: Install fish screen QC10-A: Flooding of 136th St NE Issue: Capacity Potential Solution: Install storage pond along 136th St NE and replace reverse slope culvert QC10: Channel Erosion on Hayho Creek between BNSF and 47th Dr NE Issue: Capacity/ Habitat Potential Solution: Regrade 850 LF of Creek and install native riparian vegetation QC3: Undersized Field Access Culverts Issue: Capacity/ Fish Passage Potential Solution: Replace existing culverts with 16'x6' concrete box culverts QC5A: Edgecomb Creek Channel Mitigation (North Marysville Master Drainage Plan) Issue: Mitigation/Habitat Potential Solution: Realign 2 miles of Edgecomb Creek QC7: Undersized Culvert at 152nd St NE Issue: Capacity/ Fish Passage Potential Solution: Replace existing culvert with a 15'x5' concrete box culvert QC8: Undersized Culvert and Diminished Habitat at Strawberry Fields Trail Issue: Capacity/ Fish Passage/ Habitat Potential Solution: Replace existing culvert with a 19'x7' concrete box culvert and install native riparian vegetation along 1,750 LF of channel QC6: Undersized Culvert at 152nd St NE Issue: Capacity/ Fish Passage Potential Solution: Replace existing culvert with a 17'x6' concrete box culvert QC4B: Conveyance for Regional Detention Pond No.2 Issue: Mitigation Potential Solution: Install 4,400 LF 42-inch conveyance pipe QC5B: Edgecomb Creek Conveyance Issue: Mitigation Potential Solution: Install 10,550 LF conveyance pipe (25" -

One other issue was identified involving a culvert that was found to have structural issues and is a barrier to fish. Figure 3-4 locates the Allen Creek areas described herein. AC1 (Formerly AC-AC-10) Undersized Stormwater Pipes at 95th Street NE and 67th Avenue NE The storm pipe system along 95th Street NE between 95th Place NE and 67th Avenue NE was found to have insufficient conveyance capacity by Snohomish County in the 2002 DNR No. 8. The HEC-RAS model generated for the previous report determined that flooding would occur during the 10-year event for existing and future land use. The recommended solution for this issue is to replace 227 linear feet of existing 12-inch-diameter storm pipe with 18-inch-diameter HDPE pipe. AC2 (Formerly AC-AC-03) Undersized Culvert and Erosion of the Stream Bank Along Allen Creek at 88th Street NE The 7-foot box culvert conveying water beneath 88th Street NE along Allen Creek (SD-CV-23) was identified in the 2002 DNR No. 8 as undersized, and as a velocity barrier to fish passage. A reevaluation of the culvert was conducted for current fish passage standards, where it was confirmed to be a velocity barrier for fish passage. Structural and maintenance issues were also found at this culvert. The survey crew reported the upstream section of the culvert had separated from the rest of the culvert, and a hydraulic jump is predicted at the 2-year event or less. No jump is predicted for higher flows. In addition, a 50-foot section of riprap-armored stream bank has failed. Roadway overtopping is predicted if the culvert is not maintained. The recommended solution for this issue is to replace the existing 7-foot span culvert with a 25-foot span reinforced concrete box culvert. Loose rip rap from the channel should be removed and 50 linear feet of bioengineered bank stabilization measures should be installed along the eroded south bank. AC3 (Formerly AC-JC-12) Undersized Stormwater Pipes at 61st Street NE Cul-de- Sac The storm drain system along the 61st Street NE Cul-de-Sac was identified in the 2009 Comp Plan to have insufficient conveyance capacity. The XP-SWMM model developed for this report shows flooding will occur at the 10-year event for existing land use conditions. Since the 2009 Comp Plan, a stream restoration and capacity improvement project was completed along Jones Creek, potentially reducing the severity of this conveyance issue. The Jones Creek portion of the 2002 DNR No. 8 HEC-RAS model ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 24 City of Marysville December 2016 Surface Water Comprehensive Plan Update should be updated to include these improvements, and a new hydraulic analysis should be conducted to determine the remaining flooding issues. The recommended solution for this issue is to replace approximately 580 linear feet of existing 12-inch pipe with 420 linear feet of 15-inch CPEP pipe and 160 linear feet of new 12-inch-diameter CPEP pipe. The five catch basins along this drainage line should be replaced with 48-inch, Type II catch basins. AC4 (Formerly AC-JC-11) Undersized Stormwater Pipes at 60th Place NE and the Surrounding Area The storm drain system along 60th Place NE, 64th Avenue NE, and 63rd Avenue NE was identified in the 2009 Comp Plan to have insufficient conveyance capacity. The XP- SWMM model developed for this report shows flooding will occur at the 10-year event for existing land use conditions. Since the 2009 Comp Plan, a stream restoration and capacity improvement project was completed along Jones Creek, potentially reducing the severity of this conveyance issue. The Jones Creek portion of the 2002 DNR No. 8 HEC- RAS model should be updated to include these improvements, and a new hydraulic analysis should be conducted to determine the remaining flooding issues. The recommended solution for this issue is to replace approximately 1,230 linear feet of existing 12-inch storm pipe with 450 linear feet of 18-inch-diameter CPEP pipe and 780 linear feet of 15-inch-diameter CPEP pipe. The 13 catch basins within the project area should be replaced with 48-inch, Type II catch basins. ---PAGE BREAK--- 9 9 528 Allen Creek Jones Creek Munson Creek Quilceda Creek Allen Creek J o n e s C r e ek L itt l e C oh o So u th For k A l le n Creek 67TH AVE NE GROVE ST 64TH ST NE 83RD AVE NE 108TH ST NE 88TH ST NE 100TH ST NE 47TH AVE NE 51ST AVE NE 44TH ST NE 84TH ST NE 48TH DR NE SUNNYSIDE BLVD 61ST ST NE SHOULTES RD ARMAR RD 4TH ST 9TH ST 3RD ST 80TH ST NE 47TH DR NE 84TH ST NE 51ST AVE NE M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 3-4.mxd Identified Deficiency Allen Creek King Creek Quilceda Creek Water Bodies Streams Marysville City Limits Urban Growth Boundary 0 2,000 4,000 6,000 FeetÜ AC1: Undersized Stormwater Pipes at 95th Pl NE and 67th Ave NE Issue: Capacity Potential Solution: Replace 227 LF of 12-inch pipe with 18-inch pipe AC2: Undersized Culvert and Erosion at 88th St NE Issue: Capacity/ Habitat Potential Solution: Replace existing culvert with a 25-foot span concrete box culvert and install bank stabilization AC3: Undersized Stormwater Pipes at 61st St NE Issue: Capacity Potential Solution: Replace 580 LF of 12" pipe with 420 LF of 15" pipe and 160 LF of new 12" pipe AC4: Undersized Stormwater Pipes at 60th Place NE Issue: Capacity Potential Solution: Replace 1,230 LF of 12" pipe with 450 LF of 18" pipe and 780 LF of 15" pipe IDENTIFIED DEFICIENCIES ALLEN CREEK BASIN FIGURE 3-4 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 25 Surface Water Comprehensive Plan Update December 2016 EBEY SLOUGH NORTH BASIN Two areas were identified within the Ebey Slough North Basin as needing a detailed analysis and design of both site-specific and end-of-pipe solutions to improve stormwater quality and quantity before its discharges into Ebey Slough. Figure 3-5 locates the Ebey Slough Basin areas described herein. ES1 Historic Downtown Green Retrofit Study The City of Marysville would like to provide water quality treatment to stormwater runoff that is generated within its Historic Downtown District. The downtown area discharges untreated runoff from the right of way directly into Ebey Slough, an impaired waterway and a tributary of the Snohomish River. This study will start by creating criteria for the selection of ideal areas within Historic Downtown Marysville to carry forward into the design phase. The design phase will focus on using the 2014 Department of Ecology Stormwater Management Manual for Western Washington and the 2012 Low Impact Development Technical Guidance Manual for Puget Sound to implement green infrastructure principles that mimic predeveloped hydrologic conditions for the specific project areas. These mitigation techniques may include infiltration, filtration, and transpiration to improve water quality and quantity. ES2 (Formerly ES-DT-03) Water Quality at Downtown Marina Outfall Study A study of the Downtown region should be conducted to identify alternatives and provide a design of an end-of-pipe stormwater treatment facility to accompany the water quality improvements to the 480-acre basin located upstream of the Marina area. While reductions to basin flows and creating localized treatment through LID retrofits is effective and important, significant areas of the large, older developed basin remain untreated. Creating a regional treatment facility within the system will allow for treatment of any remaining basin runoff that is not currently being addressed by treatment facilities installed to date. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 26 City of Marysville December 2016 Surface Water Comprehensive Plan Update Page Intentionally Left Blank ---PAGE BREAK--- 5 GROVE ST 4TH ST Eb e y S l o ugh Alle n C r e ek Qu i l c e d a C re e k Jones C r e e k Alle n C r e ek STATE AVE 47TH AVE NE GROVE ST 4TH ST CEDAR AVE BEACH AVE 8TH ST ASH AVE 80TH ST NE 51ST AVE NE 7TH ST 9TH ST 3RD ST 1ST ST 2ND ST QUINN AVE COLUMBIA AVE UNION AVE 10TH ST 64TH ST NE 61ST ST NE 76TH ST NE 5TH ST 35TH AVE NE DELTA AVE 49TH DR NE ARMAR RD 73RD PL NE 55TH DR NE MARINE DR NE 82ND PL NE 75TH PL NE 66TH ST NE 43RD AVE NE 81ST PL NE 53RD DR NE 67TH ST NE 77TH PL NE 50TH DR NE 74TH ST NE SHORT ST RAY FRYBERG DR 72ND ST NE 53RD AVE NE 56TH PL NE 52ND DR NE ALDER AVE ASH AVE 55TH AVE NE 3RD ST 76TH ST NE 5TH ST 33RD AVE NE 10TH ST 76TH ST NE 53RD AVE NE 6TH ST 6TH ST 49TH DR NE 2ND ST M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 3-5.mxd Identified Deficiency Allen Creek Basin Ebey Slough Basin North Quilceda Creek Basin Water Bodies Streams BNSF Railroad Marysville City Limits Urban Growth Boundary 0 1,000 2,000 3,000 FeetÜ ES1: Historic Downtown Green Retrofit Study Issue: Water Quality/Quantity Potential Solution: Identify areas, alternatives, and final design for LID improvements ES2: Water Quality at Downtown Marina Outfall Study Issue: Water Quality Potential Solution: Identify alternatives and design end of pipe treatment facility IDENTIFIED DEFICIENCIES EBEY SLOUGH BASIN NORTH FIGURE 3-5 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 27 Surface Water Comprehensive Plan Update December 2016 KING CREEK BASIN One area was identified within the King Creek Basin to be a fish passage barrier, and to have insufficient culvert sizing to allow flood debris to pass through the system. Figure 3- 6 locates the King Creek Basin area described below. KC1 Undersized Culvert Along King Creek at Soper Hill Road City staff identified significant debris buildup at the upstream opening of the 4-foot box culvert beneath Soper Hill Road along King Creek (SD-CV-157). The debris is thought to be the result of significant flooding in 2010. The culvert was also analyzed for fish passage and was determined to be a Level A barrier. The recommended solution for this issue is to replace the existing 4-foot box culvert with a 16-foot-long, 17-foot span, 7-foot rise reinforced concrete box culvert. The culvert should be countersunk 30 percent and the stream bed inside of the culvert should be constructed using a cascade-step or pool- riffle construction to comply with WDFW 2013 Guidelines. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 28 City of Marysville December 2016 Surface Water Comprehensive Plan Update Page Intentionally Left Blank ---PAGE BREAK--- 87TH AVE NE 83RD AVE NE Jones Creek Kin g C r e e k H u lbert C reek 83RD AVE NE 87TH AVE NE 79TH AVE NE 44TH ST NE 71ST AVE NE 52ND ST NE SOPER HILL RD 40TH ST NE 67TH AVE NE SUNNYSIDE BLVD 75TH AVE NE 35TH ST NE 20TH ST NE 72ND DR NE 49TH ST NE 81ST DR NE 46TH PL NE 85TH DR NE 36TH ST NE 33RD ST NE 39TH PL NE 66TH AVE NE 49TH PL NE 38TH PL NE 33RD PL NE 37TH ST NE 31ST ST NE 77TH AVE NE 29TH PL NE 76TH DR NE 22ND ST NE 24TH ST NE 21ST ST NE 72ND AVE NE 46TH ST NE 69TH AVE NE 80TH AVE NE 70TH DR NE 32ND PL NE 53RD ST NE 34TH ST NE 41ST ST NE 68TH DR NE 66TH AVE NE 40TH ST NE SUNNYSIDE BLVD 75TH AVE NE 79TH AVE NE 33RD PL NE M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 3-6.mxd Identified Deficiency Allen Creek Basin Ebey Slough Basin South King Creek Basin Water Bodies Streams Marysville City Limits Urban Growth Boundary 0 1,000 2,000 3,000 FeetÜ KC1: Undersized Culvert at Soper Hill Rd Issue: Capacity/ Fish Passage Potential Solution: Replace existing culvert with a 17'X7' concrete box culvert with a cascade step stream bed IDENTIFIED DEFICIENCIES KING CREEK BASIN FIGURE 3-6 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE ---PAGE BREAK--- City of Marysville 29 Surface Water Comprehensive Plan Update December 2016 CHAPTER 4 CAPITAL IMPROVEMENT PLAN INTRODUCTION The City of Marysville’s Stormwater Capital Improvement Plan is presented in this chapter of the 2016 Surface Water Comprehensive Plan Update. The recommended projects include structural and nonstructural elements to control both the quantity and quality of stormwater runoff, and to comply with the Washington State Department of Fish and Wildlife 2013 Water Crossing Guidelines. The Capital Improvement Plan (CIP) was developed based on input from several sources. Sources included City staff, who identified storm drainage problems, the City’s 2009 Surface Water Comprehensive Plan (2009 Comp Plan), and Snohomish County’s 2002 Drainage Needs Report No. 1 and No. 8 for the Quilceda Creek Basin and the Allen Creek Basin respectively (2002 DNR No. 1 and 2002 DNR No. which were both reviewed for projects completed and projects outstanding. Whenever an inadequately sized culvert, pipe, or channel is replaced or reconstructed, the improvement may transfer the problem It is therefore strongly recommended that all improvements include analysis of conditions. As a general rule, projects should proceed from the end of the system towards the upstream end of the system. Other stormwater capital improvement projects may arise in the future that are not identified as part of the City’s CIP presented in this chapter. Such projects may be deemed necessary for remedying an emergency situation, assessing growth in other areas, accommodating improvements proposed by other agencies or land development, or addressing unforeseen problems with the City’s storm drainage system. Due to budgetary constraints and/or addressing growth scenarios that differ from those modeled in this Plan, the construction of these projects may require changes in the proposed completion date for projects in the CIP. When new information becomes available, the City retains the flexibility to reschedule, add to, or delete proposed projects and to expand or reduce the scope of the projects, as best determined by the City. Each capital improvement project should be re-evaluated to consider the most recent relevant planning efforts as the proposed project date approaches. CAPITAL IMPROVEMENT PROJECTS This Surface Water Comprehensive Plan Update reviewed the outstanding projects from the 2009 Comp Plan. In the 2009 Comp Plan, there were 30 capital improvement projects (CIPs) identified. Of those 30 CIPs, four have been completed or have been resolved by the completion of other projects as of Summer 2016. Interviews with City ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 30 City of Marysville December 2016 Surface Water Comprehensive Plan Update staff revealed four additional CIPs including a culvert replacement in the King Creek Basin (KC1), a pipe replacement west of the Quilceda Creek Basin (QC1), flood storage at 136th Street NE (QC10-A), and a feasibility/design study for green retrofit projects in the Historic Downtown area (ES1). The recommended CIP projects scheduled for completion within future years are summarized below and are shown in Figure 4-1. Each project cost estimate includes an additional 20 percent construction contingency, 25 percent for design, engineering, and permitting, and a 9.1 percent sales tax. All project costs are based on 2016 dollars with no adjustments made for inflation in future years. The naming convention uses the initials of the drainage basin that the projects fall within, along with an identification number. It should be noted that many of the projects listed may take coordination with other agencies for permitting purposes. Permit acquisition should be considered within the project’s overall schedule. ---PAGE BREAK--- 92 531 531 9 529 9 99 99 531 9 528 5 5 5 67TH AVE NE STATE AVE 172ND ST NE 51ST AVE NE GROVE ST 83RD AVE NE 27TH AVE NE SMOKEY POINT BLVD 64TH ST NE 88TH ST NE 108TH ST NE 99TH AVE NE MARINE DR NE FORTY FIVE RD 140TH ST NE 152ND ST NE 3RD AVE NE 4TH ST 100TH ST NE CEDAR AVE 136TH ST NE 71ST AVE NE 23RD AVE NE AIRPORT BLVD 84TH ST NE 116TH ST NE 48TH DR NE 80TH ST NE 60TH ST NE ARMAR RD 172ND ST NW 44TH ST NE 99TH AVE NE SUNNYSIDE BLVD 51ST AVE NE 19TH AVE NE 132ND ST NE 51ST AVE NE 1ST ST POSSESSION SOUND Hayho Creek Quilceda Creek Allen Creek ES1 W e s t Fork Quilceda Creek QC1 Mission Creek Cougar Creek KC1 QC4 QC5 AC3 AC4 QC7 QC2 ES2 QC9 QC3 QC8 AC1 AC2 QC6 QC10 QC13 QC12 QC11 Allen Creek Q u i l ce da Cre e k Hayho Creek J o n es C r eek Edg e co m b Cre e k Po rtage C ree k Mun so n C ree k Little C oho M id d le Fork Quilc e da Cr e ek Quilced a C r eek Middle F ork Q u i l ced a Creek Quilceda Creek Jones Creek Sturgeon Creek West Fork Quilceda Creek King Creek M:\MARYSVILLE\15550.00 Surface Water Comp Plan\GIS\Maps For Plan\Figure 4-1.mxd CIP Project Allen Creek Basin Ebey Slough Basin North Ebey Slough Basin South King Creek Basin Quilceda Creek Basin Water Bodies Streams Streets BNSF Railroad Marysville City Limits Urban Growth Boundary 0 5,000 10,000 15,000 FeetÜ Ebe y Sl o u gh Steamboat Sloug h Union Slough Snohomish River CIP PROJECTS FIGURE 4-1 2016 SURFACE WATER COMPREHENSIVE PLAN UPDATE ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 31 Surface Water Comprehensive Plan Update December 2016 QUILCEDA CREEK BASIN PROJECTS QC1: Stormwater Pipe Replacement at Edward Springs Reservoir Replace 395 linear feet of 36-inch-diameter CMP pipe with 395 linear feet of CPEP pipe.

This chapter provides a summary of potential funding sources if additional funds are needed. The City has formed a stormwater utility to fund ongoing operation and maintenance, and capital improvements. An analysis to fund the planned stormwater program is provided. According to information provided by the City’s financial staff, the City’s 2015 stormwater related operating expenditures were $1,837,000. Chapter 4 shows a range from approximately $150,000 to $19 million per year in the 6-year plan for capital project expenditures. The City’s stormwater-related revenues are found to be adequate to support the planned operational expenses. However, there are significant funding deficiencies for funding capital improvements over the next 20 years. STORMWATER UTILITY RCW Chapter 35.67 allows the City to form a stormwater management utility to provide for the planning, development, management, operation, maintenance, use, and improvement of the storm drainage system. A utility is an enterprise that is operated or regulated by a government entity. The enterprise funds are predominantly self-sustaining and account for the acquisition, operation, and maintenance of governmental facilities. The City of Marysville stormwater utility formation and rate structure is codified in Marysville Municipal Code Chapter 14.19. The current 2016 stormwater service charge is set at $11.26 per month per equivalent residential unit (ESU) or single-family residence (SFR). One ERU corresponds to 3,200 square feet of impervious surface area for non- single-family properties per MMC Chapter 14.19.050. Therefore, for non-single-family residential parcels, the stormwater service charge would be $11.26 for every 3,200 square feet of impervious surface area per parcel. Also, per MMC Chapter 14.17.010, the City charges a one-time Connection Charge of $95 per new ERU. The service charge is a fee levied by the City upon all developed property within the City’s boundary. The stormwater service charge pays for improvements and maintenance to address drainage and flooding problems within the City. It was adopted to protect the environment and comply with new regulations protecting drainage systems. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 48 City of Marysville December 2016 Surface Water Comprehensive Plan Update Knowing the total number of ERUs in the City is useful in determining the service charge required to support the O&M program and planned capital improvements. Using 2015 rate revenues of $4,166,817 and a 2015 service rate of $11.04, it is estimated that the City collected revenue from 31,448 ERUs $4.1 million / $11.04 per ERU / 12 months). CAPITAL IMPROVEMENT PLAN The recommended capital improvements for the stormwater utility are detailed in Chapter 4. The list of projects, recommended schedule for implementation of the 6-year CIP, and their costs are shown in Table 5-1. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 49 Surface Water Comprehensive Plan Update December 2016 TABLE 5-1 Planned Capital Improvements 2017-2023(1) Capital Expense 2017 2018 2019 2020 2021 2022 2023 QC13: Culvert Removal and Bridge Installation along Quilceda Creek at State Avenue $6,755,000 ES2: Water Quality Treatment Facility at Downtown Marina Outfall $8,208,000 QC4B: Conveyance for Regional Detention Ponds 1 and 2 $4,901,000 ES1: Historic Downtown Green Retrofit Study $150,000 QC5A: Edgecomb Creek Channel Realignment $19,042,000 QC5B: Edgecomb Creek Conveyance $8,517,000 QC5C: Edgecomb Creek Regional Detention Facility $5,054,000 Project costs reflect estimated Year 2016 costs.

In 2015, the annual stormwater maintenance cost based on City records is $1,836,340. Table 5-2 shows 2015 operating and maintenance expenses.

As an alternative, low interest loans from the PWTF program may be used when necessary. Use of low interest loans may be financially favorable to self-financing as long as the interest costs of the loans are less than the interest that can be earned from reserve funds. The budget forecast assumptions are included in Table 5-3. The stormwater utility expenses are taken from the 2015 budget. An increase of 0.5 percent is assumed for ERUs, and a 2.0 percent increase in project and O&M costs is assumed as a conservative measure in assessing the budget. TABLE 5-3 Budget Forecast Assumptions and Baseline Operating Costs Item Assumption Number of ERUs in December 2015 Total ERUs for Rate Analysis 31,448 Escalation Factors Growth(1) 2.0% Inflation (Yearly O&M Expenses) 2.0% Construction Cost Inflation 3.0% Investment Interest 1.0% Revenue Bond 4.6% Taxes State Excise Tax 1.8% Source: City of Marysville 2015 Comprehensive Plan. PRELIMINARY RATE ANALYSIS Table 5-4 presents a simple, cash-based rate analysis based on the recommended project financing. The preliminary rate analysis is based on the following assumptions. 1. The rate of growth (ERUs), O&M costs, and project costs assumed at a 2.0 percent annual increase for each. 2. The utility has a zero balance at the start of 2016. This does not reflect actual conditions but since the City does not track the cash balance of each of its utilities, the beginning balance specifically for stormwater purposes could not be determined. Based on the assumptions listed above, the financial forecast shows the amount of incoming revenues covering the anticipated operating expenses. Using the assumed ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 52 City of Marysville December 2016 Surface Water Comprehensive Plan Update project completion dates in Table 5-1, the stormwater service charge does not have sufficient funds to accommodate the proposed 6-year CIP. Without an increase in service charges, these projects would need to be funded via other means such as grants or loans as explained in the next Section. At a minimum, it is recommended that the stormwater service charge be increased annually per a cost-of living or consumer price index factor. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 53 Surface Water Comprehensive Plan Update December 2016 TABLE 5-4 Financial Analysis Year 2017 2018 2019 2020 2021 2022 2023 Beginning Fund Balance(1) - $2,332,729 ($1,801,470) ($3,937,264) ($1,021,047) ($3,000,934) ($8,278,743) ERUs 31,448 32,077 32,718 33,373 34,040 34,721 35,415 Storm Service Rate $11.49 $11.71 $11.95 $12.19 $12.43 $12.68 $12.93 Rate Revenue $4,334,193 $4,509,294 $4,691,470 $4,881,005 $5,078,198 $5,283,357 $5,496,805 Connection Fees $59,751 $60,946 $62,164 $63,408 $64,676 $65,969 $67,289 Total Revenue $4,393,944 $4,570,240 $4,753,634 $4,944,413 $5,142,874 $5,349,327 $5,564,094 Yearly O&M Costs $1,911,215 $1,949,439 $1,988,428 $2,028,196 $2,068,760 $2,110,136 $2,152,338 Operating Surplus (Deficiency) $2,482,729 $2,620,801 $2,765,207 $2,916,217 $3,074,113 $3,239,191 $3,411,755 CIP Projects QC13: Culvert Removal and Bridge Installation Along Quilceda Creek at State Avenue $6,755,000 ES2: Water Quality Treatment Facility at Downtown Marina Outfall $8,208,000 QC4B: Conveyance for Regional Detention Ponds 1 and 2 $4,901,000 ES1: Historic Downtown Green Retrofit Study $150,000 QC5A: Edgecomb Creek Channel Realignment $19,042,000 QC5B: Edgecomb Creek Conveyance $8,517,000 QC5C: Edgecomb Creek Regional Detention Facility $5,054,000 CIP Total $150,000 $14,963,000 $4,901,000 - $5,054,000 $8,517,000 $19,042,000 Yearly Surplus (Deficiency) $2,332,729 ($10,009,470) ($12,145,264) ($9,229,047) ($11,208,934) ($16,486,743) ($32,116,987) The actual beginning fund balance for 2016 could not be determined from City financial records.

Within the State of Washington, there are several grant and loan funds available for capital improvements. Among these are the Public Works Trust Fund (PWTF), Centennial Clean Water Fund (CCWF), and the State Revolving Fund (SRF). The various grant and loan programs are briefly described below for reference. Public Works Trust Fund This program is a revolving fund loan designed to help local governments finance needed public works projects through low-interest loans and technical assistance. It was established by the Washington State Legislature in 1985 and is administered by the Public Works Board. The Legislature cancelled the 2010 to 2016 biennium funding cycles. Loan repayments and tax revenue streams that fund the program continued to be deposited in the fund and yet, it has remained uncertain as to what level of funding may be available through the program in the future. Currently, the Board is tentatively offering $100 million state-wide in construction loans for the 2017 funding cycle. Department of Ecology Integrated Funding Program The Department of Ecology administers several loan and grant programs that can be used to fund the following:  Stormwater capital improvements including stormwater system retrofits;  Low-impact development projects;  Inventories of stormwater sources;  Public education and communication;  Review and preparation of stormwater regulations;  Mapping;  Source control activities; and  Establishing and refining stormwater utilities. The funding programs include the Centennial Clean Water Grant program (state funds), the Clean Water Act Section 319 Grant program (federal funds), the Stormwater Financial Assistance Grant Program (state funds) and the Washington State Revolving Fund Loan program (federal and state funds). A common application is available for funding from the Ecology-administered programs. The programs are competitive and the majority of the funding available is in the form of low-interest loans. DEBT FINANCING Two forms of debt financing are available for capital improvements including general obligation bonds and revenue bonds. G.O. bonds are backed by the “full faith and ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 55 Surface Water Comprehensive Plan Update December 2016 credit of the City” and are paid for through levies. These bonds require voter approval before they can be implemented. A less common means of financing capital improvements associated with stormwater projects is through the use of revenue bonds. The City, like other municipalities, is capable of issuing tax-exempt bonds. The principal and interest of such bonds are repaid from revenue generated from a utility, such as a water, sewer, or stormwater utility. This type of funding may be offered without voter approval. However, in order to qualify to sell revenue bonds, the City must establish that its net operating income is equal to or greater than its debt coverage factor, typically 1.4, multiplied by the annual principal and interest due for all outstanding bonded indebtedness. Utility rates have to be set high enough to ensure revenue bond repayment. FUTURE CAPITAL IMPROVEMENT PLAN The total cost, in 2016 dollars, of the 2017-2023 CIP is over $52 million. The stormwater utility revenues alone are adequate to support the planned operational expenses. However, they are inadequate to cover the capital expenses over the 6-year planning period, without any service rate increases. Further, the amount of funds available for capital projects will decrease due to increasing O&M costs. However, the total cost of the projects scheduled for years 7 through 20 is over $15 million (2016 dollars), for which there would be a significant revenue shortfall, were rates to remain unchanged. ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 56 City of Marysville December 2016 Surface Water Comprehensive Plan Update Page Intentionally Left Blank ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers City of Marysville 57 Surface Water Comprehensive Plan Update December 2016 APPENDIX A STORMWATER BASE MAP ---PAGE BREAK--- Gray & Osborne, Inc., Consulting Engineers 58 City of Marysville December 2016 Surface Water Comprehensive Plan Update Page Intentionally Left Blank ---PAGE BREAK--- " " " " " " " " " !
