The vision of the Public Lands Advisory Committee is to create cooperative relationships with public lands managers to ensure that public lands in Kittitas County provide access for the public and are sustainably managed for multiple uses while providing opportunities for outdoor recreation and economic benefit to County residents; and WHEREAS: On June 9, 2016 the Kittitas County Board of Commissioners Adopted Resolution 2016-076 approving a county recreation plan: The Kittitas County Park, Recreation, and Open Space (PROS) Plan wherein Policy 6.5.1 states, "Coordinate and support a comprehensive system of off-road 4 -wheel drive and all -terrain vehicle trails and backcountry roads that access scenic, environmental, historic, and open space attributes throughout Kittitas County expanding and linking existing trail systems in the urban and upper county areas into area -wide networks including the Wenatchee National Forest, Teanaway Community Forest, Naneum Ridge State Forest, LT Murray, Oak Creek, Wenas, Colockum, and Whiskey Dick Wildlife Areas; and WHEREAS: Kittitas County Board of Commissioners support "No Net Loss" for public access on public roads in Kittitas Count and across the State of Washington; and WHEREAS: The definition for "No Net Loss" was vetted through the Public Lands Advisory Committee with participation from public land manager; NOW THEREFORE BE IT RESOLVED: That the Board of County Commissioners defines how the community achieves "No Net Loss" for public access on public roads as being: To achieve "No Net Loss" any established road or roads that are currently open which are permanently eliminated for the use of public travel by way of motorized transportation on public land or a public road should be replaced in the system by another road giving passage into the same geographical area. The following methods, appearing below, are used to achieve "No Net Loss" for public access on public roads. How to Mitigate for Road Closures (1) If the State or Federal Agency can demonstrate unequivocally why the permanent road closure is necessary and/or mandatory with no alternative to give passage into the same geographical area they can replace that road loss with a comparable road network by going through a public process with meetings and outreach efforts conducted in the county affected. This should aim to provide a road network that is equal to or superior to the original road as determined by public input. (2) When a State or Federal Agency purchases private land with existing roads they shall go through a public process with meetings and outreach efforts conducted in the county affected to assist in determining which roads shall remain open for public use by motorized transportation. In this process roads should aim to provide access to distinct geographic areas, scenic or interesting wildland experience, and lands that have a defined historical importance.

Recreation. and Open Space (PROS) Plan wherein Policy 6.5.1 states, "Coordinate and support a comprehensive system of off-road 4 -wheel drive and all -terrain vehicle trails and backcountry roads that access scenic, environmental, historic, and open space attributes throughout Kittitas County expanding and linking existing trail systems in the urban and upper county areas into area -wide networks including the Wenatchee National Forest, Teanaway Community Forest, Naneum Ridge State Forest, LT Murray, Oak Creek, Wenas, Colockum, and Whiskey Dick Wildlife Areas; and WHEREAS: Kittitas County Board of Commissioners support "No Net Loss" for public access on public roads in Kittitas Count and across the State of Washington; and WHEREAS: The definition for "No Net Loss" was vetted through the Public Lands Advisory Committee with participation from public land manager; NOW THEREFORE BE IT RESOLVED: That the Board of County Commissioners defines how the community achieves "No Net Loss" for public access on public roads as being: To achieve "No Net Loss" any established road or roads that are currently open which are permanently eliminated for the use of public travel by way of motorized transportation on public land or a public road should be replaced in the system by another road giving passage into the same geographical area. The following methods, appearing below, are used to achieve "No Net Loss" for public access on public roads. How to Mitigate for Road Closures (1) If the State or Federal Agency can demonstrate unequivocally why the permanent road closure is necessary and/or mandatory with no alternative to give passage into the same geographical area they can replace that road loss with a comparable road network by going through a public process with meetings and outreach efforts conducted in the county affected. This should aim to provide a road network that is equal to or superior to the original road as determined by public input. (2) When a State or Federal Agency purchases private land with existing roads they shall go through a public process with meetings and outreach efforts conducted in the county affected to assist in determining which roads shall remain open for public use by motorized transportation. In this process roads should aim to provide access to distinct geographic areas, scenic or interesting wildland experience, and lands that have a defined historical importance.

Cook RECOMMENDATION: Informational only — no action required. BRIEFING SUMMARY: • Public Works (PW) recently met with area irrigators and the City of Ellensburg • Weather conditions have remained favorable (through 03-22-2019) • Freezing night temperatures have been favorable • PW is expecting localized flooding at Whiskey and Mercer BACKGROUND: On Tuesday (03-19-2019) PW maintenance management staff met with representatives from the City of Ellensburg and the three main irrigation districts (EWC, KCRD and Cascade). We reviewed current areas of concern and reviewed general known areas of lower County flooding. Reports are favorable from Upper County relative to the amount of snow and ice in main irrigation canals. DISCUSSION: Some amount of rain is expected this weekend. Concern is for daytime temperatures exceeding 50 degrees Fahrenheit coupled with over a quarter inch of rain. Soil conditions remain completely saturated and any amount of precipitation is expected to immediately runoff the landscape. Snow pack at upper elevations appear to be consolidating well (low water content) adding to confidence of a minimal flood event this spring. Local irrigation managers' report that that snow pack conditions represent approximately 80 percent of normal going into the runoff season. In conclusion, we have benefitted greatly from freezing conditions at night with relatively moderate daytime temperatures. This mix of temperature conditions is allowing a sustained orderly melt off of area snow pack with minimal impact to area streams. FISCAL IMPACTS: PW is budgeted for flood fight operations in the 2019 maintenance budget. Additional funding is available in the County's Flood Control Zone District 2019 budget. ATTACHMENTS: None.

Cook RECOMMENDATION: Support the preferred flood alleviation alternative submitted to the Federal Aviation Administration (FAA). BRIEFING SUMMARY: • Public Works (PW) recently submitted a preferred flood alleviation proposal to the Federal Aviation Administration as part of ongoing Environmental Assessment work at Bowers Field (ELN) • Flood modeling suggests significant benefit to the airport and downstream property owners • The FAA will now be lobbied for including flood alleviation into the Capital Facility Plan BACKGROUND: PW's hydrology and hydraulics consultant (Watershed Science and Engineering) utilized the County's Whiskey and Mercer Creeks two dimensional flow model testing various flood alleviation options for ELN. The work is funded by the Environmental Assessment begin conducted in support of the Capital Improvement Plan. During recent years, flood flows have forced intermittent closures of runway 11-29. DISCUSSION: The following preferred actions are being presented to the FAA as an Appendix to the EA (EXHIBIT 1): • Extend/cleanout the taxiway ditch to the north end of runway 11-29 • Construct an east -west ditch along abandoned taxiway at north end of runway 11- 29 to capture and route overland flow away from Bowers Field and towards Whiskey Creek to prevent flooding across runways Page 1 of 3 PUBLIC WORKS BOARD OF COUNTY COMMISSIONERS WORK SESSION STAFF REPORT • Construct storage ponds at west end of Bowers Field to detain flow from the new east -west ditch and allow controlled release to Whiskev Creek. Size culverts at the pond outlet to restrict outflow to Whiskey Creek and prevent any increase to peak flooding downstream. Construct storage ponds to the west of Whiskey Creek on Kittitas County property upstream of Hungry Junction Road. Size ponds and outlet structures to attenuate peak flow on Whiskey Creek and to work in conjunction with storage ponds west of Bowers Field to avoid downstream flood impacts on Whiskey Creek. The actions listed above are expected to alleviate flooding across runway 11-29 and reduce shallow flooding on the western edge of the airport property. New and expanded ditches route overland flow away from both airport facilities and downstream properties between Whiskey and Mercer Creeks. The flood storage ponds provide enough live storage to prevent routed flow from increasing peak flood depths downstream while still draining within 12 hours of the flood peak to meet FAA requirements for surface impoundment. The complete technical memorandum from WSE is attached as EXHIBIT 1 for Board review. Actual implementation of the storage proposal will entail significant additional engineering and is expected to require additional funding. FISCAL IMPACTS: The cost of implementing the various preferred alternatives is currently being developed Once costs are in hand, PW will approach the FAA requesting funding for constructing the identified preferred alternatives.

The airport is located within the 100 -year floodplain of both Whiskey and Mercer Creeks, and planned airport improvements have the potential to impact flood hazards on and downstream of the airport property. WSE updated an existing HEC -RAS 2D hydraulic model of Whiskey and Mercer Creeks to evaluate several alternatives for reducing flood risk to airport facilities without negatively impacting downstream properties. Results from this analysis will support the Bowers Field Environmental Assessment (EA) being prepared by Century West Engineering (Century West). BACKGROUND The Bowers Field EA currently being prepared by Century West is based on planned implementation of the 2018-2023 portion of the Bowers Field Airport Master Plan Capital Improvement Program. Short term projects covered under the EA include rehabilitation of runway 7-25, runway 11-29, runway 11-29 parallel taxiway, and AC hold areas, in addition to other site grading, pavement removal, and taxiway development. WSE was contracted by Century West to complete a hydraulic analysis for selecting a preferred set of actions to reduce or eliminate problematic flooding at the airport and to demonstrate that proposed actions covered by the EA will not worsen 100 -year flood conditions downstream from the airport. Problematic flooding on the airport runway under existing conditions is the result of overland flow escaping Mercer Creek northeast of the airport both upstream and downstream of Hungry Junction Road. Most of this flow concentrates in a taxiway ditch parallel to runway 11-29 before ponding and flowing across the runway near the intersection of runway 11-29 and runway 7-25. Flow overtopping the runways ultimately impacts airport facilities and private property downstream of the runway intersection. HYDRAULIC MODELING WSE completed hydraulic modeling based on an existing unsteady HEC -RAS 2D hydraulic model of Whiskey and Mercer Creeks that was constructed fora study to update FEMA flood maps in Kittitas County (WSE, 2018). The model was modified to run in the latest version of HEC -RAS (version 5.0.6). Peak flow hydrology for Whiskey and Mercer Creeks was developed previously for the 2018 FEMA mapping study (WSE, 2018). 24-hour inflow hydrographs applied to the model simulate a rain -on -snow event representing typical historical flooding in the region.

The 100 -year flood was therefore the focus of the alternatives analysis. WATERSHED I' f• 12 ALTERNATIVES ANALYSIS The with -project model surface was then modified to evaluate alternatives for flood reduction at Bowers Field and mitigation of flood impacts to downstream properties. The following alternatives were identified through discussion between WSE, Century West, and Kittitas County, and the analysis and results for each evaluated alternative are discussed in the sections below: Increasing in -channel flow conveyance of Mercer Creek by modifying the channel banks and/or replacing the culvert under Hungry Junction Road • Construction or modification of drainage ditches to capture and route flow around the airport • Construction of flood storage (in combination with modifications to drainage ditches) INCREASED IN -CHANNEL CONVEYANCE OF MERCER CREEK -BANK MODIFICATION Flow escaping the Mercer Creek channel downstream of Hungry Junction Road contributes to overbank flooding of airport facilities. Actions considered to increase channel capacity and reduce overtopping included raising the channel bank at a channel bend on airport property downstream of Hungry Junction Road. WSE updated the with -project model geometry to represent multiple potential bank configurations and ran the model to simulate the 100 -year flood event. An example of the resulting change in 100 -year flood depth from raising the channel bank (compared to existing conditions) is shown in Figure 3. For any one of the configurations tested, raising the channel bank reduced peak flooding at the airport but retained more flow within the Mercer Creek channel, leading to increased flood depths along Mercer Creek downstream from the airport. No feasible measures were identified to mitigate these impacts. INCREASED IN -CHANNEL CONVEYANCE OF MERCER CREEK -HUNGRY JUNCTION CULVERT REPLACEMENT The Mercer Creek culvert under Hungry Junction Road is undersized and contributes to backwatering and road overtopping that floods the north end of Bowers Field and the airport runways. WSE updated the with -project model to simulate replacing the existing 4 -ft corrugated metal pipe (CMP) culvert with a larger structure and ran the model to simulate the 100 -year flood event. An example of the resulting change in 100 -year flood depth from a combination of the upsized culvert and raised channel bank (compared to existing conditions) is shown in Figure 4. Results indicate reduced road overtopping along Hungry Junction Road and reduced peak flooding at the airport. However, more flow within the Mercer Creek channel led to increased peak flood depths along Mercer Creek downstream from the airport. No feasible measures were identified to mitigate these impacts. DITCH MODIFICATION OR CONSTRUCTION The following alternative ditch locations and alignments were evaluated: Clean out the existing taxiway ditch along the east side of runway 11-29 to capture and route flooding from the airport runways downstream to Mercer Creek WATERSHED T- r p 3 Construct a new ditch from east to west along an abandoned taxiway between runway 11-29 and Hungry Junction Road to capture water overtopping Hungry Junction Road and route it west toward Whiskey Creek • Extend the constructed east -west ditch (described above) south along the west side of the airport to activate flood storage within an existing depression on airport property WSE updated the with -project model geometry to represent each of these alternatives, including variations on ditch length, size, and outlet location. Results indicate a reduction in flooding at airport infrastructure but significantly increased flood depths at and downstream of each of the ditch outlets. Ditch options were therefore considered in combination with flood storage (see next section) to reduce peak outflow and eliminate downstream impacts. FLOOD STORAGE CONSTRUCTION Multiple flood storage configurations were evaluated in conjunction with drainage ditch construction to reduce peak flows and mitigate downstream impacts from routing flooding away from airport facilities. Storage alternatives were simulated by adding multiple low -height berms in series to maximize storage within the steeply sloping terrain and to reduce the required height of each berm. Each storage area was modeled with a low-level culvert outlet to meter outflow and allow stored water to drain during the flood recession. Three storage configurations were examined: 1. Storage ponds at the northwest corner of Bowers Field, fed by a constructed east -west ditch (described above). Water would be released Whiskey Creek through a culvert outlet. Storage ponds at the southwest corner of Bowers Field (an alternative to the first configuration) covering a natural depression in this area that would provide additional storage volume. Water would be released to Whiskey Creek through a culvert outlet. 3. Storage ponds to the west of Whiskey Creek and north of Hungry Junction Road. These ponds would be located away from the airport on property owned by Kittitas County. Berm layouts for each storage configuration were determined through an iterative process to achieve adequate flood storage. Berms were simulated by creating vertical walls on top of the existing model terrain without any changes to the surrounding terrain surface. Equivalent storage volume could also be achieved through a combination of shorter berms paired with excavation of the area upstream. Pond outlets (culverts) were sized to maximize storage volume during the flood peak while allowing for adequate drainage during the flood recession. Final configuration results showed that storage alternatives 1 and 3 were effective at reducing 100 -year peak flows and mitigating downstream impacts of flow routed through the ditches. However, storage alternative 2 resulted in increased downstream flood depths that could not be mitigated due to the location of the drainage outlet. Figure 5 shows the change in 100 -year flood depth (compared to existing conditions) resulting from storage alternative 2 in conjunction with the Mercer Creek bank -raising measure described above, indicating a significant increase in downstream flood depths downstream of the storage outlet. �=WATERSHED F [; e a Additional locations for flood storage were considered, including areas northeast, east, and southeast of the airport runways. These options were eliminated due to limitations caused by terrain features, slope, and available area; therefore, no hydraulic analysis of these options was completed. PREFERRED ALTERNATIVE WSE presented results of alternative model simulations to the County and Century West during online meetings on 1/15/19 and 2/4/19. At the 2/4/19 meeting, the team selected a preferred alternative consisting of the following combination of measures to reduce flooding to airport facilities and mitigate downstream impacts (see Figure 6 diagram): • Extend/cleanout the taxiway ditch to the north end of runway 11-29 • Construct an east -west ditch along abandoned taxiway at north end of runway 11-29 to capture and route overland flow away from Bowers Field and towards Whiskey Creek to prevent flooding across runways • Construct storage ponds at west end of Bowers Field to detain flow from the new east -west ditch and allow controlled release to Whiskey Creek. Size culverts at the pond outlet to restrict outflow to Whiskey Creek and prevent any increase to peak flooding downstream. • Construct storage ponds to the west of Whiskey Creek on Kittitas County property upstream of Hungry Junction Road. Size ponds and outlet structures to attenuate peak flow on Whiskey Creek and to work in conjunction with storage ponds west of Bowers Field to avoid downstream flood impacts on Whiskey Creek. The taxiway ditch cleanout extends approximately 1700 additional feet parallel to the runway from the existing cleanout, and the constructed east -west ditch extends approximately 2800 feet from the access road at the north end of Bowers Field to the abandoned taxiways at the west end of the airport property. Constructed storage ponds consist of berms ranging from a maximum of 4 to 7 feet and 600 to 1000 feet long with aft x 3ft to 8ft x Sft rectangular outlets. The five storage ponds on Bowers Field provide a peak storage volume of approximately 21 acre-feet during the 100 -year flood event. The four storage ponds upstream of the airport provide a total peak storage volume of approximately 12 acre- feet during the 100 -year flood event. Resulting 100 -year flood depths and change in depth from the preferred alternative are shown in Figures 7 and 8, respectively. In general, the preferred alternative routes flow around the airport through a combination of ditches and storage, eliminating flooding across the airport runways and downstream properties between Whiskey and Mercer Creeks. The storage ponds fill to maximum capacity during the flood peak, then drain completely within 12 hours. Figure 8 indicates that there are some changes in flood depth outside of the constructed ditches and storage ponds, although all of these impacts are very minor (less than 0.1 ft change in depth) and are generally contained on County property. WATERSHED P a k> P 15 CONCLUSION Bowers Field airport currently experiences problematic flooding across its runways during the 100 -year flood event on Whiskey and Mercer Creeks, prompting a hydraulic analysis to asses flood reduction measures. The preferred alternative determined by this analysis includes a combination of actions that alleviate flooding across runway 11-29 and reduce shallow flooding on the western edge of the airport property. New and expanded ditches route overland flow away from both airport facilities and downstream properties between Whiskey and Mercer Creeks. The flood storage ponds provide enough live storage to prevent routed flow from increasing peak flood depths downstream while still draining within 12 hours of the flood peak to meet FAA requirements for surface impoundment.
