CRYSTAL CREEK FLOOD STUDY AND MAP UPDATES Mark Cook introduced Arden Thomas to present the item for discussion. Arden Thomas gave background on the study for Crystal Creek and the input received from the City of Roslyn and City of Cle Elum. Arden Thomas stated that previous modeling was done in the 1970's by the Federal Emergency Management Agency (FEMA) and the new study utilized better topography and site condition information along with advanced modeling techniques. Arden Thomas continued that the critical information coming out of the study is that there will be no expansion of the mapped floodway designation and proposes minor map revisions within the one hundred (100) year and five hundred (500) year floodplains. Arden Thomas added that staff will be attending the City of Cie Elum Council meeting scheduled for today's date for a presentation. Discussion was held. Staff was directed to move forward with outreach to affected property owners. FLOODPLAINS BY DESIGN LETTER OF SUPPORT Mark Cook gave background on a previous request from Floodplains by Design and a request for signature on a letter of support to the Governor for seventy (70) million dollars in funding for 2021-2023. Mark Cook continued that Public Works has secured funding from this program for projects and acquisition. Mark Cook added that the Governor's Office is now sending the request for funding to the legislature and a similar action is being requested to show support. Vice -Chairman Laura Osiadacz made a motion to approve the Chair's signature on the letter of support with Chairman Brett Wachsmith seconding the motion. Motion passed 2-0. 2021-01-11 MINUTES SNOQUALMIE PUBLIC UTILITY DISTRICT WATER RIGHT AND HYAK PARKING UPDATE Mark Cook reported that Tom Hastings with Snoqualmie Public Utility District (SPUD) noticed him of the approval by the Department of Ecology for foreign water rights. Mark Cook gave background on the project in progress by SPUD for a wastewater treatment plant and the Board authorizing two hundred and fifty thousand dollars ($250,000) from the Public Facilities Fund supporting the project. Discussion was held. Mark Cook stated that there are still issues with parking at Hyak by recreational users and the facility shared with SPUD is being blocked. Mark Cook gave background on the work staff has done with implementing parking fines and with the approval of updating the LAIRD to include impound yards as an allowable or conditional use. Staff can work on a proposal to contract with a tow company to remove 417egally parked vehicles using an impound yard proximate to Hyak. Further discussion was held. PUBLIC WORKS PERMIT FEE REVIEW Mark Cook gave background on the last fee update completed in 2017 by Public works and other county departments utilizing a fee model implemented with a consultant. Mark Cook continued that staff is now collecting data to support an increase of fees along with internal processes of permit routing. Mark Cook added that he will have a complete briefing for the Board by the end of the first quarter of 2021 and a proposal for implementation by the end of the second quarter of 2021. Discussion was held. LEASE OF PUBLIC RIGHT OF WAY FOR PARCEL NUMBER 901833 Mark Cook reported that a lease with a property owner was established in 1961 for a structure located partially in the Vantage Highway right of way. Mark Cook continued that the lease is set to expire in October of this year and the original lessee has since sold the property with the lease not being assignable. Mark Cook added that the new property owner is looking to renew the lease. Mark Cook stated that it is problematic for the county to allow incursions of private property into county right of way. Mark Cook commented staff is recommending termination of the lease and working with the property owner on a solution. UPPER COUNTY TRUCK TRAFFIC RESTRICTION Mark Cook gave background on the action taken by resolution in 2018 establishing truck traffic restrictions annually from May 15th to September 15th on certain upper county roads. Mark Cook continued that at the last Upper County Traffic Committee meeting members inquired about making the restriction year-round. Mark Cook added that with the absence of a Commercial Vehicle Officer employed by the Sheriff's Office it is hard to enforce a year-round restriction. Discussion was held. Staff was directed to attend a Special Meeting 2021-01-11 MINUTES scheduled for Wednesday, January 13th at 3:30pm with the Sheriff for further discussion. Staff was also directed to notify the Upper County Traffic Committee of the meeting and solicit for attendance. OTHER BUSINESS: There was no other business for discussion. Meeting adjourned at 2:36 pm. 2021-01-11 MINUTES KITTITAS COUNTY COMMISSIONERS KITTITAS COUNTY, WASHINGTON Brett Wachsmith, Chairman KITTITAS COUNTY DEPARTMENT OF PUBLIC WORKS PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS STUDY SESSION STAFF REPORT STUDY SESSION DATE: January 11, 2021 TOPIC: Crystal Creek Flood Study and Map Updates ACTION REQUESTED: Direction to Staff LEAD STAFF: Arden Thomas RECOMMENDATION: Direct staff to submit finalized Letter of Map Revision Application and conduct outreach. BRIEFING SUMMARY: • The Kittitas County Flood Control Zone District (FCZD) received funding from the Federal Emergency Management Agency (FEMA) to conduct a Crystal Creek Flood Study and to update the official maps used by FEMA and community officials based on the outcomes of the new study. • FCZD staff has been coordinating with Cle Elum and Roslyn Communities to gather information about Crystal Creek flooding concerns and integrate this study with Roslyn's stormwater planning and capital improvement efforts. • Compared to the original FEMA investigation conducted in the late 1970s, the new Crystal Creek study utilized better topographic and site condition information, including surveys of all stream crossings, and more advanced modeling techniques. • While FEMA has been updating the flood maps county -wide, the FEMA -led effort did not include any new studies for Crystal Creek. Changes to the Crystal Creek floodplain mapping as part of the FEMA -led effort is due to improved topography information. • The hydrologic and hydraulic study for Crystal Creek is complete. Within Cle Elum, the model results and proposed remapping indicate that there should be no expansion of the floodway designation and proposes minor revisions in areas currently mapped as within the 100 -year and 500 -year floodplain. • After the Letter of Map Revision application materials are finalized, it will need to be submitted by the three National Flood Insurance Communities (Cities of Clc Elum and Roslyn and Kittitas County) affected by the study and the proposed map changes. Page I of 9 PUBLIC WORKS BOARD OF COUNTY COMMISSIONERS WORK SESSION STAFF REPORT The Kittitas County Flood Control Zone District (FCZD) received funding from the Federal Emergency Management Agency (FEMA) to conduct a Crystal Creek Flood Study and to update the official maps used by FEMA and community officials based on the outcomes of the new study. Crystal Creek was chosen for the flood study based on local community interest and the desire for the FCZD to begin remapping priority watershed in Upper Kittitas County. FEMA -funded flood studies and remapping efforts must conform to P'EMA standards. Studies can be either detailed or approximate. In approximate areas, the 100 -year floodplain is identified but the study does not establish base -flood elevations or identify the floodway. National Flood Insurance Program (NFIP) communities are required to regulate development within these 100 -year floodplain but have little information about these areas. Detailed studies not only identify the footprint of the 100 -year floodplain, but also identify base -flood elevations, 500 -year floodplains, and floodways. Floodways have very high regulatory standards, including a prohibition on new residential structures. 500 - year floodplains have no minimum regulatory requirements, though communities can choose to regulate these areas. FEMA is in the process of updating the FEMA floodplain maps throughout the County. This effort did not include any new studies for Crystal Creek, and differences between the "old" 1981 maps and "New" maps anticipated in 2021 for the Crystal Creek floodplain are due to more accurate topography data available from the 2011 LiDAR flight. DISCUSSION: The results of the Crystal Creek flood resulted in no large changes in our understanding of flood risk or extent within the City of Cle Elum. In downtown Cle Elum, the hydraulic modeling indicates that during the 100 -year flood, Crystal Creek floods overbank north of 2"d Street and continues east as shallow flooding with less than 1 foot of depth. This flooding was also identified in the work maps associated with the 1981 FEMA maps. Since the 1981 FEMA maps identify these areas as Zone B (areas with between a 1% and 0.2% annual change each year), in the LOMR we propose to maintain the same flood designation. This designation, which is also referred to as the 500 -year floodplain, would not create a mandatory flood insurance requirement, but the City of Cle Elum could consider utilizing this flood study for stormwater planning and project implementation. Since there is risk of shallow flooding, even during the 100 -year flood event, the City of Cle Elum consider applying higher building standards within this area identified as a 100 - year floodplain. The Kittitas County Flood Control District conducts outreach aimed at informing residents about upcoming map changes. The FCZD proposes sending out notices to any landowners impacted by mapping changes and coordinating with the City of Cle Elum so that both FCZD staff and Cle Elum staff are listed as contacts on outreach materials to landowners within the City of Cle Elum. FISCAL IMPACTS: The Crystal Creek flood study and remapping effort was largely supported through FEMA funding. The Flood Control Zone District has included outreach, including staff time and required materials) in is 2021 budget.

WATERSHED T- SCIENCE & ENGINEERING MEMORANDUM To: Mark Cook, Kittitas County Public Works From: Chris Frei, P.E., Marissa Karpack, E.I.T., Watershed Science & Engineering Date: December 21, 2020 Re: DRAFT - Crystal Creek and Cedar Gulch Creek Hydraulic Analysis 1.0 INTRODUCTION Watershed Science & Engineering (WSE) was hired by the Kittitas County Department of Public Works to complete hydraulic modeling and analysis to evaluate flood risk along Crystal Creek and Cedar Gulch Creek in Kittitas County, WA. Model results were used to prepare flood plain, mapping and supporting technical documentation necessary to update effective FEMA Flood Insurance,Rate Maps (FIRMS) as part of a Letter of Map Revision (LOMR). This work was partially funded t.htough a FEMA Cooperating Technical Partnership (CTP) grant. 2.0 LOCATION Crystal Creek and Cedar Gulch Creek are located in Kittitas County, WA. This current study covers 4.5 miles of Crystal Creek from northeast of the city of Rioslyo (Roslyn) 'to the confluence with the Yakima River at the City of Cle Elum (Cie Elum, see Figure 1), and,,2.5 miles.s f Cedar Gulch Creek from the foothills north of Roslyn to where the creek enters the city's piped stormwater system near W Nevada Ave. 3.0 EFFECTIVE FEMA MAPPINE., Effective mapping for Crystal Creek ai)d Cedar Gulch Creek are based on a 1981 Flood Insurance Study (FIS). The lower 9900 few of Crystal,Creek within Cle Elum was studied by detailed methods. Flooding along the channel cor iclor is mappdd as Zone AE and has a coincident floodway (no encroachments). Overbank flooding within Cle Elum is mapped as Shaded Zone X (shallow 100 -year flooding). All other reaches of Crystal Creek and daf Gulch were studied by approximate methods and are mapped using the Zone A designation. A 1991 LOMB (91-10-22P) removed Zone A flooding within Roslyn by demonstrating that 100 -year flooding on Cedar Gulch Creek would be contained within Roslyn's piped stormwater system. The current study does not update mapping within the region covered by the LOMR. Roslyn is in the process of upgrading their stormwater system and will assess the need for updated flood mapping after those improvements have been implemented. For the current study it was assumed that Roslyn's stormwater system has minimal impact to flood routing through the city. This is because the piped stormwater system outfalls to Crystal Creek at the same location that any overland flooding would return to Crystal Creek.

A separate 1D/213 pseudo steady state HEC -RAS model was used to simulate flooding along the lower portion of Crystal Creek including Cie Elum. The lower model encompassed the entire reach of Crystal Creek that was previously studied using detailed methods. Model layout and extents for the three (3) models are shown in Figure 2. 1D model reaches were developed by: 1. Developing model cross section layout and geometry data within ArcGIS 10.5 2.

Stream channel survey was collected by the County from October 1St to November 26th, 2019 to support the current study. Survey was completed at 108 cross sections and 26 water crossing structures including bridges and culverts. WSE additionally traveled to the study reaches on July 22, 2020 to examine hydraulic conditions, observe crossing structures, and record structure geometry.

WSE used StreamStats to apply the regression equations and determine flow quantiles at key flow change locations. Parameters used in the flow analysis are presented in Table 2. Peak flow results are presented in Table 3. The resulting Crystal Creek 100 -year flow at the downstream model boundary is approximately twice the peak flow values used in the effective Flood Insurance Study (FEMA 1981).

The upper and lower Crystal Creek models were run for the five flow quantiles (10-, 25-, 50-, 100-, 500 -year events) shown in Table 3. Flows were specified at the upstream end of each reach, confluence locations, and downstream of major tributary inflows. Normal depth boundary conditions were applied at the downstream end of Cedar Gulch Creek and the lower Crystal Creek model reach, and at the downstream (east) boundary of the 2D area in Cie Elum. Friction slopes were determined based on average channel/basin slope at each location. The upper Crystal Creek steady ID model used a fixed water surface boundary condition that was based on the steady state water surface elevation output from the lower Crystal Creek model. Model simulations for Cedar Gulch Creek and Upper Crystal Creek were performed using the subcritical t flow regime option. Model simulations for the lower Crystal Creek ],* D model were performed using the subcritical unsteady flow option with constant inflows (pseudy state). For model stability, flows in the lower Crystal Creek model were ramped up to the V staff ipflow shown in Table 3 over approximately 48 hours. 4.2.2 MODEL RESULTS Model results for the 100 -year event on Cedar QWch Creek, fpr Crystal Creek, and Lower Crystal Creek are included in Appendix A.

An effective floodway currently e4"r the lower 9900 feet of Crystal Creek but was defined as "coincident with the 100 -year boundary" (FtMA, 1981). WSE determined an updated floodway boundary through an encroachment analysis by the following steps: Within the lower model: Applied the effective floodway boundary to the updated model using blocked obstructions. The boundary had to be adjusted in several areas where the effective floodway boundary was outside the current 100 -year boundary. • Ran the model to simulate the 100 -year flood, with floodway enforced. Compared floodway water surface elevations to BFEs to determine if floodway rise was less than 1 foot at all cross sections. WATERSHED P a g e 19 SCIENCE 4 ENGINLERING The majority of the floodway was contained within the 11) portion of the model; however, a short section of floodway was extended into the 21) model to prevent surcharges greater than 1 -ft near the downstream model boundary. The floodway boundary in the 2D area was set by raising the elevation of the terrain surface outside of the floodway by a scaler (10 ft). For the upper Crystal Creek model, the downstream model boundary condition was set to the floodway watersurface elevation from the lower model. Floodway boundaries were generally set at the edge of the 100 -year floodplain and resulted in little to no rise. The resulting floodway data tables for Crystal Creek are included in Appendix C. No floodway was determined for Cedar Gulch Creek which will retain the approximate Zone A mapping designation. 5.0 MAPPING WSE completed floodplain mapping for the 100 -year event on Cedat Gulch Creek and the 100- and 500 - year events on Crystal Creek based on hydraulic modeling resulo, TXhew mapping will replace current "effective" FEMA mapping of the creeks shown on Fop panelss•,�530096000113, 53009502348, 5302990005A, 5300950231B, and 53009502328. The eW ve study of Cr al Creek and Cedar Gulch Creek used "approximate" methods and therefore was ppe ing the "Zone A" designation. Updated mapping for Cedar Gulch Creek will maintain the Zone A de! ation. Updated Mapping for Crystal Creek uses the Zone AE designation and includes a flo r—Propos rystal Creek mapping ties into effective mapping at the Yakima River in Cie Elum.

The automated floodplain mapping feature of HEC -RAS (RASMapper) was used to rate titer surface elevations and initial flood extents based on HEC -RAS model output and the DEM. T"stream reaches of both Crystal and Cedar Gulch Creek are steep (6- 20%) and confined within a ravine, the DEM (which was based on LiDAR) did not contain sufficient channel detail to accurately map in the areas between cross sections. Consequently, this resulted in "dry" creek sections, where the projected water surface elevation was less than the channel bottom elevation in the DEM. In these regions, WSE delineated the floodplain based on channel width at the bounding cross sections. Base Flood Elevation (BFE) contours were then created to represent the final 100 -year water surface elevation. BFEs were generated based on the modeled 100 -year water surface elevation and then trimmed to the edge of the final floodplain polygon. 19_01� WATERSHED 110 SCIENCE & ENGINEERJNG 6.0 SUMMARY ■ WSE developed hydraulic models for Cedar Gulch Creek and for the upper and lower reaches of Crystal Creek and applied new peak flow hydrology to determine peak flood elevations and areas of inundation. Model results were used to produce the information necessary to update floodplain mapping, including the workmaps and flood profiles provided. REFERENCES Chow, V. T. (1959). Open -channel hydraulics.

FLOOD MAP BASICS. The Federal Emergency Management Agency (FEMA] coordinates disaster response. The National Flouu insurance Program (NFIP) provides flood insurance to property owners as well as education and assistance to lessen flood damage in flood -prone areas. A FIRM will generally show: Flood Insurance Rate Maps fFIRM,' are maps . a community's base flood elevations, created by FEMA and used by the NFIP for flood- plain management, mitigation, and insurance pur- ' flood zones, and poses. 0 floodplain boundaries.

This funding program requires that the flood hazard maps be updated when the study is finished and also gives the District the tools to update these maps once again when flood alleviation projects are implemented. HOW CAN I REDUCE MY INSURAAICF RATE? • Lower your property`s exposure to flooding by elevating your home, Encourage participation in the Community Rating Service (CRS), a voluntary program that can reduce flood insurance premiums when an community exceeds NFIP minimum requirements. When Kittitas County was accepted into CRS in 2014, it lowered flood insurance premiums by 20%, • Apply for a Letter of Map Change (LOMC) if you think your building is incorrectly shown as be- ing in a high risk area. A Letter of Map Amendment (LOMA) can be requested if a property is shown as being in a high risk flood zone but is actually on naturally high ground, • Consider a high deductible to lower your premium if financially possible, • If mapping revisions will show your property in a Special Flood Hazard Area for the first time, don't wait to explore insurance options. You may be eligible for a lower premium during the first 12 months after a map change and buying a policy before the new maps go into effect can save more money. it},tite In"r 1-rop ri+.

Before initiating the study, the FCZD's hydraulic consultant met with members of the Cle Elum and Roslyn Communities to gather information about Crystal Creek flooding X$101KNOORA Compared to the original FEMA investigation conducted in the late 1970s, the new Crystal Creek study utilized better topographic and site condition information, including surveys of all stream crossings, and more advanced modeling techniques. • While FEMA has been updating the flood maps county -wide, the FEMA -led effort did not include any new studies for Crystal Creek. Changes to the Crystal Creek floodplain mapping as part of the FEMA -led effort is due to improved topography information. • The hydrologic and hydraulic study for Crystal Creek is complete. Within Cle Elum, the model results and proposed remapping indicate that there should be no expansion of the floodway designation and proposes minor revisions in areas currently mapped as within the 100 -year and 500 -year floodplains. • After the Letter of Map Revision application materials are finalized, it will need to be submitted by the three National Flood Insurance Communities (Cities of Cle Elum and Roslyn and Kittitas County) affected by the study and the proposed map changes. 411 N. Ruby St., Suite #1 TEL (509) 962-7523 Ellensburg, WA 98926 FAX (509) 962-7663 Dept. of Public Works Page 2 BACKGROUND The Kittitas County Flood Control Zone District (FCZD) received funding from the Federal Emergency Management Agency (FEMA) to conduct a Crystal Creek Flood Study and to update the official maps used by FEMA and community officials based on the outcomes of the new study. Crystal Creek was chosen for the flood study based on local community interest and the desire for the FCZD to begin remapping priority watershed in Upper Kittitas County. FEMA -funded flood studies and remapping efforts must conform to FEMA standards. Studies can be either detailed or approximate. In approximate areas, the 100 -year floodplain is identified but the study does not establish base -flood elevations or identify the floodway. National Flood Insurance Program (NFIP) communities are required to regulate development within these 100 - year floodplain but have little information about these areas. Detailed studies not only identify the footprint of the 100 -year floodplain, but also identify base -flood elevations, 500 -year floodplains, and floodways. Floodways have very high regulatory standards, including a prohibition on new residential structures. 500 -year floodplains have no minimum regulatory requirements, though communities can choose to regulate these areas. FEMA is in the process of updating the FEMA floodplain maps throughout the County. This effort did not include any new studies for Crystal Creek, and differences between the "old" 1981 maps and "New" maps anticipated in 2021 for the Crystal Creek floodplain are due to more accurate topography data available from the 2011 LiDAR flight. DISCUSSION: The results of the Crystal Creek flood study did not result in the expansion of the floodway and in many places resulted in a reduction of the footprint of the 100 -year floodplain. There is a section within unincorporated Kittitas County, just downsteam of Roslyn, where more detailed modeling indicated that an expansion of the 100 -year floodplain is necessary. Newly constructed and significantly improved buildings within a FEMA -mapped 100 -year floodplain must be built to heightened building standards that address flood risk. Previously, an approximate study was used to map Crystal Creek upstream of No. 5 Mines Rd. The new modeling extended the detailed modeling the entire mapped length of Crystal Creek. Detailed modeling identifies base flood elevations, which allows for development requirements to be tailored to flood risk of the site. In the absence of a base flood elevation, a uniform requirement of building the first floor of a home two feet above highest adjacent grade must be applied. Flood insurance rates for new homes are also lower when a base flood elevation is available. The Kittitas County Flood Control District conducts outreach aimed at informing residents about upcoming map changes. The FCZD proposes sending out notices to any landowners impacted by mapping changes and coordinating with the Cities of Cle Elum and Roslyn in outreach efforts.. 411 N.

November 3, 2020 Dear Governor Inslee 1 Dear Legislative Leaders, Thank you for your support of Floodplains by Design, a popular, cost-effective public -private - tribal -agricultural partnership that delivers critical results for communities, conservation and Washington's urban and rural economies. We write today to respectfully request that you include $70 million in your 2021-23 biennial capital budget for Floodplains by Design. Administered by the Department of Ecology, Floodplains by Design has been supporting tribal nations, farmers, and flood managers across the State to transform how floodplains are managed since 2013. Local demand for this type of collaborative multi -benefit investment has only grown and become more sophisticated in its ability to provide local results and leverage public investment. file:lllkitntlprivatelpworks_privlmark.cookl2021%20FbDISupportlo20capital%20funding%20for°1a20Floodplains%20by%20Design.html[115/2021 8:13:38 AM] Support capital funding for Floodplain by Design Among the 2021 FbD projects are broadly supported packages that protect farmland; restore estuaries; remove, improve or set back levees, improve agricultural drainage, reduce flood hazards, restore salmon and shellfish habitat, and more. These projects are the result of hard work by local governments, tribes, farmers, watershed groups, the conservation community, salmon recovery advocates and state and federal agencies to come together to craft creative and unique suites of actions that deliver reach and watershed scale change. They would create an estimated 2,689 jobs impacting at least 38 legislative districts throughout the state, many of which are currently experiencing nearly double-digit unemployment. Floodplains by Design projects reduce flood risk, restore salmon habitat, deliver vital resources in support of agriculture, increase access to public lands and outdoor recreation, and create local jobs. This funding is a tremendous investment opportunity. By prioritizing and rewarding collaborative, integrated decision-making, the State can reduce conflict in local communities and better spend limited public dollars. Investment in Floodplains by Design, paired with flood dollars, salmon and orca recovery investments and agricultural programs can begin to deliver results at a pace and scale demanded by growth, climate change and failing infrastructure. Washingtonians depend on healthy, livable, safe floodplains, and local communities need state support and incentives to better manage river systems in holistic way that builds community, economic and environmental resilience. At a time when Washington's iconic orca and the salmon they depend on are in peril, Floodplains by Design has reconnected more than 7,000 acres of floodplain — critical habitat for chinook salmon — and restored more than 50 miles of river. Climate change is increasing flows in our rivers by tens of percentage points and flood managers are working hard to reduce risk and protect public safety. Since 2013, Floodplains by Design projects have removed 434 homes and other structures from high-risk areas and reduced flood danger in 59 communities. Farmland in Washington state is disappearing at an alarming rate, increasing floodplain development pressures and associated flood risk. Floodplains by Design projects have protected more than 1,300 acres of working lands, including farmland, dairies, aquaculture sites and ranches, creatively funded projects that keep critical floodplain dairies viable by investing in new technologies to treat dairy waste while improving water quality, and improved infrastructure benefiting another 7,800 acres of working lands. Resilient communities The program not only helps sustain local economic productivity, the infrastructure works it funds creates hundreds of local high -paying engineering and construction jobs. This year has been remarkably challenging for Washingtonians across our state in many ways — with a public health emergency, continued climate -change exacerbated disasters, social unrest and economic losses for many. Beyond the health impacts of COV1D-19, community and economic systems are strained, and workers across the state have lost their livelihoods. Capital investments get people to work. Capital investments in flood risk reduction simultaneously protect communities from devastating floods that would be even harder to recover from. Investments in salmon recovery sows the seeds for a return of harvestable fish for cultural, recreational and commercial purposes. Investment in our farm communities keeps food local, keeps our economy diversified and supports hard-hit rural communities. filc:111kitnt1private(pworks_privlmark.cookl2021%20FbD/Support%20capital%20funding°/o20for%24Floodplains%20by%20Dcsign.html[11512021 8:13:38 AM] Support capital funding for Floodplains by Design It has also been a time when more and more families find solace in the outdoors. Floodplains by Design has created or improved 25 public areas where Washingtonians and visitors can go to find respite and renewal in nature — creating more opportunities for improving not just physical resilience, but spiritual resilience as well. It's clear that now, more than ever, it is time to invest in Washington's people and natural places. Floodplains by Design supports cultural, ecosystem and economic well-being — since 2013, it has created 2,755 new jobs across Washington, supporting 45 watershed -scale projects in 16 counties. Scientists find fish in the newly built restoration sites, farmers see another year they can farm, and many people are proud to have jobs that contribute to a State they love. By working toward the goals held by diverse people in a community and by working at a landscape scale, communities are coming together to shape their own future — one in which they are more resilient to the impacts of climate change, including abnormally destructive floods, mudslides and extreme storms. A record of results From the Olympic Peninsula to the Palouse, and Bellingham to Vancouver, Floodplains by Design projects have improved outcomes for flood risk reduction, working lands and fish and wildlife habitat along 15 major rivers. Flood managers, tribal nations, farmers and community organizations are developing clear plans for how to solve their community problems. This is much -deeded work. As communities work together more closely and link funding sources, staff resources, and previously disconnected plans — a path forward is ever increasingly emerging. Because communities are seeing actual results that matter, resources better leveraged, and time spent more efficiently, the program continues to grow as a trusted tool that can respond to creative solutions brought forward by local collaborations. More than half the 7,217 acres of floodplains FbD projects have reconnected since the program began is the result of work that was funded in the 2019-21 biennium, when the Legislature appropriated $50.4 million for the program — its highest appropriation yet. Floodplains by Design is poised to rapidly scale up multiple -benefit results in communities across Washington with increased public investment. Time to Invest We ask for your support for $70 million in capital funding for Ecology to incentivize collaboration on flood risk reduction, salmon recovery and working lands protection and enhancement through its Floodplains by Design program. With a capital investment of $70 million, Floodplains by Design projects in the 2021-23 biennium would leverage another $91 million in funding from other sources, resulting in $161 million in support for getting Washingtonians back to work. This investment will also increase our collective climate resilience, reducing risk, protecting land and water and restoring habitat and — perhaps most importantly — fueling the hope and hard collaborative work represented in the suite of projects that are ready to go.

LEAD STAFF: Mark R. Cook RECOMMENDATION: None required, informational briefing only. BRIEFING SUMMARY: • A foreign water right has been granted to Snoqualmie Public Utility District (SPUD) — see EXHIBIT 1 • Approximately 54 million gallons of water outside of Kittitas County (Snoqualmie River Watershed) will now flow in County streams (Coal Creek) • Construction of phase one of the new wastewater treatment plant will be awarded on January 11, 2021 (the Board authorized a $250,000 Public Facility Fund grant towards the effort in 2020) • Public parking continues plaguing our joint ability managing snow removal this season • Recruitment of a towing company no longer is dependent on unauthorized land use, as the Board recently amended land use in the Snoqualmie Pass LAMIRD allowing impound yards BACKGROUND: The Board of County Commissioners (BoCC) awarded $250,000 of Public Facility Fund (0.09 funding) to SPUD in 2020 supporting the new wastewater treatment plant construction. Supporting the expanded water supply effort in the LAMRID, the Department of Ecology recently granted a "foreign" water right to SPUD allowing water extracted in King County and discharged as treated wastewater effluent in Kittitas County. In December 2020, the BoCC authorized impound yards within the LAMRID — clearing the way for Public Works (PW) to solicit towing services in Hyak. DISCUSSION: The recently granted water right to SPUD results in approximately 54 million gallons of Snoqualmie River Watershed water as SPUD treated wastewater being discharged into Kittitas County receiving water (Coal Creek). This new significant supply is expected to benefit Bull Trout recovery in Upper Kittitas County. Page 1 of 3 Public Works "Work Session Staff Report", 2021 It has taken several years preparing for the implementation of aggressive parking enforcement in Hyak. In 2019, the BoCC authorized parking fines in Hyak and recently took action on the final regulatory item in the way of fully implementing parking enforcement by allowing impound yards in the LAMRID. The BoCC will recall that PW has not aggressively pursued a towing contract in Hyak believing that "stranded" motorist could be a physical risk if vehicle recovery was not proximate to Hyak. The road is now clear for pursuit of a towing contract so long as the contract includes an impound facility proximate to Hyak. PW could pursue issuing a request for proposal requiring an impound yard proximate to Hyak as a condition of towing contract award. FISCAL IMPACTS: None identified at this time.

The DOE has approved our request for the foreign water right in Kittitas County. This will grant the District access to nearly 80 million gallons in Kittitas County. This is in addition to the 54 million gallons we currently have in King County. A unique and significant step for the District to meet the growth that is occurring at Snoqualmie Pass. I say unique since it is a foreign water right. If not granted, the District would have to attempt to purchase water rights from the lower county and transfer up to the pass. So what we accomplished is a win for the upper and lower county. On Monday the District will award the contract to construct phase 1 of the new wastewater plant. The District will construct a membrane bio reactor treatment facility. The cost is $4.6 million (estimates were $3.1). The project is approved and funded by the USDA. Construction will start as soon as the snow melts. We hope to start phase 2 of the wastewater plant in 2023. This summer will work on a well sighting project and find the best locations to drill some wells. We are also working with the DOE on getting approved for a non -consumptive well. This would be a well strictly used for snow making and may only be 10% consumptive. Which is great so that we do not use up too much of our potable water rights. Making snow for a low cost will greatly help the Ski Area to open sooner and generate revenue. Just wanted to let you and the Commissioners know that we do have some great things happening up here. Give me a call if you have any questions.

Cook and Liz Remeto RECOMMENDATION: Informational briefing only. BRIEFING SUMMARY: • Public Works (PW) fee schedule was adopted in 2017 • Fees were typically set at 25% of calculated costs • PW permit fees have been averaging approximately $250,000 per year since 2017 • PW staffing changes in 2018 committed $100,000 of sustainable permit revenue towards offsetting the cost of new positions in the department: (Environmental/Transportation Planner) • PW fees have not been re-evaluated since adoption in 2017 • PW is currently evaluating all fees along with our internal permit processes and will return to brief the Board of our results by February 22, 2021 BACKGROUND: Kittitas County utilized a consultant developing a fee model for use by all departments of the Board in 2016. Permit fees were adopted for use in PW in 2017. The Board of County Commissioners (BoCC) set fees typically at 25% of forecasted total cost. Since adoption, PW annual permit fees average approximately $250,000 per year. Permit fees have not been reviewed since adoption in 2017. DISCUSSION: As PW prepares outreach efforts in 2021 defining critical funding shortfalls implementing the deferred maintenance needs of roads and bridges over the next twenty years, it seems prudent to revisit PW permit fees in advance of the outreach effort. PW staff have been diligent tracking true costs of most permits while failing to track true costs of other permits. PW management is currently reviewing all permit processes responding to poor tracking performance on some permits. The goal is to reduce the amount of job cost coding that is the likely cause of poor cost tracking. Some permit cost tracking is good, and these permit fees are being targeted for adjustment (meaning current funding level is not covering the true cost). Once a thorough review is completed by PW Page 1 of 3 Public Works "Work Session Staff Report", 2021 management staff, we will return to the BoCC and brief the results of our analysis. Preliminary analysis indicates numerous permits are not covering the true cost of staff efforts at current reduced levels (25% of calculated cost). FISCAL IMPACTS: Any significant forecast revenue changes resulting from permit revenue adjustment will be brought to the BoCC for possible budget adjustment the second quarter of 2021. Permit fees by year in dollars ($): 2020 292,295.50 2019 276,258.00 2018 251,208.00 2017 178,318.00 2016 47,860.00 ATTACHMENTS: Exhibit 1: Resolution 2017-064 Page 2 of 3 Public Works "Work Session Staff Report", 2021 EXHIBIT 1: RESOLUTION 2017-064 Page 3 of 3 Public Works "Work Session Staff Report", 2021 BOARD OF COUNTY COMMISSIONERS COUNTY OF KITTITAS STATE OF WASHINGTON RESOLUTION NO: 2017- Liz TO ADOPT THE 2017 PUBLIC WORKS DEPARTMENT FEES FOR THE KITTITAS COUNTY AIRPORT FUND, KITTITAS COUNTY ROAD FUND AND KITTITAS COUNTY FLOOD CONTROL FUND WHEREAS: The Department of Public Works has submitted proposed 2017 fee schedules for the Kittitas County Airport Fund, Kittitas County Road Fund and the Kittitas County Flood Control Fund; and WHEREAS: These fees have been reviewed to determine the rate appropriate for full cost recovery with adjustments on certain fees to provide a phased in rate of full cost recovery; and WHEREAS: A public hearing opened on February 7, 2017, at 2:00 p.m. in the Commissioners' Auditorium was continued to March 21, 2017 at 2:00 p.m. where the public written comment period was extended to March 31, 2017 at 4:00 p.m. NOW, THEREFORE BE IT RESOLVED: The Board of County Commissioners, after due consideration, does hereby adopt the proposed 2017 Public Works Department Fee Schedules for the Kittitas County Airport Fund, Kittitas County Road Fund and Kittitas County Flood Control Fund as shown in Exhibit `A', Exhibit `B' and Exhibit `C'_ ADOPTED this 4th day of April, 2017.

Cook RECOMMENDATION: Notice the current resident of lease termination and direct removal of the encroachment. BRIEFING SUMMARY: • Since 1981, Public Works (PW) has leased right of way to a county resident allowing an encroachment of an outbuilding (shed) in county right of way. • The lease was renewed in 2001 and is set to expire in October 2021. + The lease does not contemplate "assignability" and the property recently exchanged ownership and PW desires terminating the lease on the October 2021 date. PW recently directed a hay press operation to abate a sign placed in county right of way along the same roadway (Vantage Highway). BACKGROUND: Since 1981, PW has been collecting lease payments for a structure partially located within county right of way (five feet). The current lease rate is $15 per year. The lease does not contemplate assignability. DISCUSSION: Recently, PW directed the removal of partially completed sign at a hay pressing facility that was erected inside of county right of way. The practice of allowing incursion of private improvements into county right of way is problematic. A county resident was recently allowed to retain a fence in county right of way associated with a fish barrier removal project. The agreement requires removal upon notice of PW for future road improvement. The ongoing lease arrangement at 4820 Vantage Highway does provide for a similar removal upon notice of a pending road improvement project. The current lease is not assignable. PW prefers removal of the structure prior to lease termination on 10/31/2021. FISCAL IMPACTS: More money is spent processing the lease payment annually than is received in payment.

Cook RECOMMENDATION: Do not extend the period of truck traffic restrictions defined in Resolution 2018-076 at this time. BRIEFING SUMMARY: • Resolution 2018-076 establishes a restriction on truck traffic (FHWA Group 9 and bigger) annually from May 15th to September 15'h. • The Upper County Traffic Committee desires extending the prohibition to a complete year. • Public Works (PW) does not support the request owing to a lack of a commercial vehicle officer being able to support the prohibition through sustainable enforcement activities. BACKGROUND: Responding to resident concerns of increasing heavy truck traffic adding to congestion on certain Upper County roads (Nelson Siding, Westside, Mohar, Upper Peoh Point and Thorp Prairie); the Board of County Commissioners (BoCC) enacted Resolution 2018- 076 (EXHIBIT 1). Recently, the Upper County Traffic Committee requested PW solicit the BoCC for support of extending the period of prohibition to year-round. DISCUSSION: In the absence of sustained commercial vehicle enforcement along the identified road network, extending the prohibited period of operation is expected to exacerbate an already stressed enforcement condition. The action is akin to reducing the posted speed limit when the science suggests the action as unwarranted. Driver behavior will not change sufficiently in the absence of enforcement. Once the BoCC directs sufficient resource allocation supporting a full-time commercial vehicle officer, the request should be revisited. Page 1 of 3 Public Works "Work Session Staff Report", 2021 FISCAL IMPACTS: No current funding allocation in 2021 supporting a commercial vehicle officer enforcing the current restrictions.
