Subject: North Kitsap Service Center Alternative Analysis — DRAFT

Project No.: 33305

Purpose and Need This memorandum provides a project overview, a description of existing site conditions, programming validation, an alternative discussion by discipline and a multi-criteria decision matrix comparing two site plan alternatives, and recommendation of the preferred site alternative. Once Kitsap County has selected the preferred alternative, the Otak team will provide environmental review documentation, permit assistance, and final plans, specifications, and estimates in preparation for construction. Refinements to the preferred site plan will be made throughout the final design phase.

As this memorandum is intended to address the various differences between the two site plan alternatives, it will not cover all technical aspects of the project, leaving that discussion for the forthcoming design report.

Project Overview Otak was selected to provide professional services for the design of a new road maintenance shop on 16 acres of recently purchased undeveloped property located south of NE Rova Road, and east of State Route 307/Bond Road NE, in north Kitsap County (Parcel No. 062602-2-064-2007). The new road maintenance shop will provide administrative offices for three (3) supervisory personnel; crew dispatch, training, locker and washroom areas for thirty (30) operation employees; vehicle maintenance bays; outdoor covered canopy parking for selected maintenance equipment and vehicles; uncovered parking for private vehicles; yard storage areas for maintenance materials; equipment and vehicle wash bay; and a vehicle and equipment fueling station.

A Moderate Risk Waste Facility (MRWF) will also be located on the parcel. It is probable that additional office space for a Sheriff’s Department employee will also be required. It is expected that, where feasible, use of common facilities will be considered.

Collectively, the road maintenance shop and MRWF have been designed as the North Kitsap Service Center for the purpose of improving public outreach communication.

Most utility services are available to the site including power, water, and cable. Natural gas is not available; neither is sanitary sewer which will require design of an on-site septic system (OSS). Environmentally sensitive areas exist on, or adjacent to the parcel. Of the 16 acres, approximately six (6) acres exist within critical area setbacks.

Kitsap County completed preliminary programming for the project, of which the following building space metrics were determined:

. Administration/Crew Space 4,500 square feet . Vehicle/Equipment Maintenance Bays 14,000 square feet . Covered Canopy Equipment/Vehicle Storage 9,600 square feet . Fueling Station/Vehicle Wash 5,880 square feet . Salt Storage 2,520 square feet . MRWF 3,650 square feet, minimum

Existing Site Conditions The site is generally flat to gently sloping with rolling hills. The topography within the northeast third of the site gradually slopes to an existing drainage channel. A stream channel crosses the site from north to south, beginning at NE Rova Road and extends to the southeastern corner of the site. The remaining site generally slopes towards the south. Ground surface elevation of the site ranges between 220 and 244 feet NAVD88.

The site is heavily vegetated and forested with young to mature conifer that are up to 44-inch diameter at breast height (DBH); young to mature deciduous trees ranging up to 45-inch DBH; and groundcover consisting of ferns, ivy, woody shrubs, and herbaceous ground cover.

Subsurface soil conditions consist of topsoil 1 to 1.5 feet below ground surface (bgs), underlain by weathered and un-weathered Vashon till ranging in depths of 18 to 26.5 feet bgs. There is perched groundwater; static groundwater is near 18 feet bgs.

The site is located in a Type III Limited Area of More Intensive Rural Development (LAMIRD) land use overlay. A Type III LAMIRD is a land use type designated in the comprehensive plan that is an unincorporated commercial and industrial node containing isolated cottage industries and other small businesses. A commercial tree farm and the Arness Septic Pumping business are located south of the subject property. Adjacent properties immediately to the north and east are either developed as rural residential or are undeveloped. The subject property is over 15 acres in size and is currently undeveloped. The property was created through a binding site plan initiated by Arness Tree Farms, the previous owner.

The site is accessed via a driveway from SR 307/Bond Road NE; this driveway currently allows unrestricted turning movements (right/left in and right/left out). A second driveway from NE Gunderson Road is accessed by internal roadways.

Existing stormwater facilities are present adjacent to the site. Two state owned stormwater conveyance pipes run under SR 307/Bond Road NE from the west property line.

Programming Validation Otak and stakeholders vetted and verified the preliminary program, space metrics, and plans generated by TCF Architecture of Appendix A. The team reviewed the preliminary programming for the project providing general building space metrics.

The provided program and space allocation matrix was compiled, updated and reviewed. This has been preliminarily reviewed by Jacques Dean at Kitsap County. Some program elements have been removed and consolidated. Refer to Appendix B.

Concerns that the subject facility programming adequately accommodates future service level demands for the road maintenance shop in terms of materials and equipment storage, building space for staff needs, and vehicle and equipment parking are addressed in the memo of Appendix C. Programming the Moderate Risk Waste Facility for current and anticipated waste streams is covered by the July 14, 2021 Final Kitsap County HHW Programming Report prepared by Special Waste Associates.

Building program and site relationships were reviewed, refined and applied through the development of schematic building floor plans and site plans. Site observation and feedback through on-site meetings with the client team and stakeholders have been integrated into the current site and building plan alternatives.

The design team leveraged the findings from field trips to the existing Kitsap County Household Hazardous Waste Facility, Public Works Annex, and South and North Road Maintenance Shops on April 22, 2021; as well as a June 2, 2021 field trip to the Pierce County Central Maintenance Facility (refer to Appendix D). These lessons learned and best management practice ideas are proposed to be integrated into the site plan alternatives and buildings of the North Kitsap Service Center

In March, Otak held a conference call with Keith Swearingen and Jacques Dean to review and coordinate plan elements and reorganize program elements for greater efficiency.

A conference call with Darren Schwend from Notkin a P2S Inc. Company (P2S) and a potential maintenance consultant provided key input to assist the design team with refinement of the proposed maintenance bay to improve functionality.

Floor plans of the Moderate Risk Waste Facility and Road Maintenance Shop were developed based on the preliminary program, program validation, and field trip observations. These floor plans are developed as a first stage of architectural design, and to establish building footprints to use in the site planning process. Opportunities for facility growth and expansion have been incorporated into the floor plan, including flexible meeting and storage rooms and second level MEP spaces that could grow in size internally. The fabrication shop on the end is configured to convert to a heavy maintenance bay if additional growth is required.

Alternatives Description Site plan Alternatives A and B were developed as shown in Figure 1. Alternative A which impacts no critical areas was developed as a baseline to fully understand if there is sufficient room to store materials and maneuver about the site with vehicles and equipment amongst all the required program elements. Significant similarities and differences are summarized in the tables below, and described in further detail in the subsequent Site Planning Discipline Discussion section of this memo.

k:\project\33300\33305\projectdocs\site planning\20210801 alternatives analysis tech memo.docx North Kitsap Service Center Page 4 of 11 Alternative Analysis — DRAFT August 4, 2021

Similarities The Moderate Risk Waste Facility and Administration Building/Maintenance Shop are placed in the southwest and northern margins of the site, respectively, with the same floorplan footprints Avoids impacting Wetland A, the unnamed stream, and their 150-foot buffer

Differences Alternative A Alternative B Wetland C and its 50-foot buffer Avoids impacts Impacts Usable space 10.54 acres outside Wetland A 11.88 acres outside Wetland A, and C, stream, and buffers stream, and buffers Moderate Risk Waste customer Clockwise rotation* Counterclockwise rotation* vehicle approach queuing * These sub-alternatives were developed for discussion purposes; later thinking was a counterclockwise rotation places drivers closer to building and staff

Alternatives Discussion by Discipline Site Planning Common to Both Alternatives A & B The site layout places the Moderate Risk Waste Facility at the south/west corner of the site at the future intersection of the proposed LAMIRD road and Bond Road NE. This will allow the waste facility to be easily viewable and accessed by the public. This facility will be fenced separately and accessed from the adjacent Kitsap Service Center. Residents will queue up in two parallel vehicle lanes and circulate to the waste drop-off area, then exit the facility through the same entrance as their arrival.

The Administration & Crew Building / Vehicle Maintenance Shop is sited at the north end of the site, east of Bond Road NE and south of NE Rova Road. It is anticipated the building creates minimal noise compared with other activities on the site, and is therefore more compatible with residential areas to the north and east. The Administration & Crew portion of the building is located at the center of the site, along with an employee parking area to the south of the building. Additional covered vehicle parking is provided in this central portion of the site as well.

At the central axis of the maintenance facility is the main vehicle circulation route that heads north from the new site entrance at the southeast corner of the site. This alignment provides immediate access to the fueling station and vehicle wash. A traffic circle is located at the center of the site, south of the Administration & Crew Building to allow for vehicles to turn around and exit the site without the need to circulate around the vehicle maintenance shop. Vehicles to be maintained can circulate around the maintenance facility and enter and exit through the maintenance bays.

The bulk materials storage area is located along the eastern margin of the site away from residential areas. This portion of the site has the most activity due to vehicle traffic and noise generated by road maintenance vehicles coming and going from the site. Dump trucks and pups entering the bulk materials area can make a complete U-turn within this area; semi-truck and trailer can exit via the adjacent traffic circle.

The perimeter of the Moderate Risk Waste Facility will be fully fenced along the road frontages and along the 150-foot stream buffer. All vehicle access points will have locking gates.

Unique to Alternative A Wetland C Buffer averaging is proposed in this area in which up to 25% of the buffer width can be decreased as long as the net area of buffer is compensated for at other location along the buffer. This wetland provides a significant natural vegetation buffer between the publicly accessed MRWF, and the road maintenance and operations functions.

Unique to Alternative B Alternative B eliminates Wetland C. Corresponding wetland impacts are proposed to be mitigated off site. As a result, this alternative provides more opportunity to expand buildings and site features for future demands.

Site Landscape / Buffers A 20′ landscape buffer is required at the northwest and southern project boundary. For both alternatives, the proposed buffer for the project has been expanded to 40 feet along Bond Road NE and Rova Road, to maintain as many existing trees as possible to aid in the vegetated screening for the project, and to comply with Kitsap County staff input to emulate the look and feel of the Public Works Annex yard located outside Bremerton. This buffer screening will be designed to provide a site barrier where the project abuts adjacent roadways. Existing trees in this area will be supplemented with additional native trees and groundcover per Kitsap County Code requirements. All existing vegetation within the 150′ stream buffer setback is maintained.

Vehicle Maneuverability Autoturn software vehicle path simulations were run for both site plan alternatives for an American Association of State Highway Transportation Officials (AASHTO) WB-67 vehicle, an Interstate Semitrailer (see Figure 2.) Please note that the simulation includes routing to the Moderate Risk Waste Facility loading dock, and through the road maintenance and operations portion of the site. An Autoturn vehicle simulation that matches dump truck and pup trailer is not available, therefore the analysis also includes depicting Kitsap County provided dump truck and pup turn radii to test the space for vehicle maneuverability in the bulk storage area. Vehicle maneuverability appears to be sufficient for both Alternatives A and B.

Buffer averaging is utilized at portions of each site plan alternative to locate the edge of pavement to aid in more efficient vehicle maneuverability and program element arrangement. See the section titled “Environmental and Permitting” for more details on buffer averaging.

Architectural The design team used the preliminary programming documents provided by the County to initiate the design of the facility. After reviews and meetings with consultants, the County, and with internal stakeholder engagement, the current plans were developed and have been evolving as new information comes to light.

Maintenance Building The maintenance building is comprised of three basic parts; road maintenance administrative offices and crew space, Equipment Services Department (ESD) offices, and the ESD maintenance shop (refer to Figure 3). The office portion includes the entry, lobby restroom and locker room. Offices and the training/conference room are on the second floor, along with storage and mechanical/electrical/plumbing (MEP) spaces that can grow in size. The ESD portion has two levels with some open to above space, and

k:\project\33300\33305\projectdocs\site planning\20210801 alternatives analysis tech memo.docx North Kitsap Service Center Page 6 of 11 Alternative Analysis — DRAFT August 4, 2021

the four heavy maintenance bays have double high spaces open to the sawtooth roof form. This provides a north facing roof for light and a south facing roof for solar panels.

Maintenance Building Areas: Level 1: 14,989 sf, Level 2: 4,534 sf – Total: 16,523 sf

Household Waste (HHW) Building (refer to Figure 3) The HHW building provides double high open spaces for sorting and storage, and a two-level volume to accommodate the office and general functions with MEP and storage on the second floor.

The program and functionality of the HHW building was discussed in a meeting with David Nightingale, Rick Gilbert and Darren Schwend, and several adjustments made in plan. Note: as a topic of discussion, the reverse flow of traffic at the moderate waste facility illustrated on the site option B stemmed from a recent comment from a coordination call. This needs to be discussed and studied further to accommodate clear site circulation and adequate queuing.

The sheriff’s office has been proposed to be located in the HHW facility to be grouped with the other public facing building elements at the street. The team would like to confirm the hours of operation and access to the HHW grounds as there may be security.

Household Waste: Level 1: 8,600 sf, Level 2: 1,431 sf – Total 10,031 sf

There are no significant differences between the building plans on the different site options.

Civil Engineering and Utilities Grading The site grading is intended to match the elevations of the proposed LAMIRD road along the south edge of the project area. Otak has contacted the road design engineer, Map Ltd., requesting their vertical datum. Once received, we will apply a datum equation to refine the profile of the project site approach road.

Preliminary grading plans have been developed as shown in Figure 4. Otak is confident the grading for either alternative can be refined and optimized during the 30% design to evaluate cost tradeoffs associated with stormwater conveyance and flow control, retaining walls, and the minimization of imported and exported grading materials.

There is a substantial hill in the northeast portion of the project area that will need to be leveled to accommodate the proposed facilities. This material will be used as fill in existing low areas throughout the site to provide a relatively flat surface throughout. Grading has been designed to encroach on the critical area buffers as little as possible, however using buffer averaging there are some areas where cut and fill slopes can impinge on these buffers (see Environmental and Permitting section for further information on buffer averaging). It is assumed because both grading and retaining walls will be optimized, the anticipated cost estimate is of negligible difference, and is therefore not included in the relative cost estimate of Appendix F.

Both cut and fill retaining walls are proposed on the west side of the site in order to minimize disturbance and maintain the existing wooded buffer along Bond Road NE as much as possible.

Utilities Alternatives A and B are not materially different in the placement of utilities to service the site, so for the purposes of this analysis, they were not evaluated for differences between the two alternatives. k:\project\33300\33305\projectdocs\site planning\20210801 alternatives analysis tech memo.docx North Kitsap Service Center Page 7 of 11 Alternative Analysis — DRAFT August 4, 2021

Stormwater Engineering . Development of the Kitsap County North Road Facility will require compliance with Kitsap County Code, and Minimum Requirements 1 through 9 in the 2021 Kitsap County Stormwater Design Manual and 2019 Ecology Stormwater Management Manual for Western Washington. The minimum requirements will require stormwater facilities to meet the runoff treatment, flow control, and wetlands protection requirements. On-site stormwater management best management practices (BMPs) are required to be evaluated for feasibility. Due to the required space for the County’s operations, there will not be large, forested areas outside of the critical areas on site to allow for full dispersion of runoff without stormwater facilities. Infiltration of stormwater is also considered infeasible due to glacial till soils underlying the project site. Therefore, on-site stormwater management BMPs are considered to be infeasible at the site. . Runoff treatment will be required to include pretreatment, oil control, as well as enhanced runoff treatment facilities due to the intended use of the project site. The recommended types of runoff treatment facilities included limited areas with bioretention with underdrains, and underground biofiltration vaults. The recommended flow control facilities consist of underground detention vaults.

Alternative A consists of approximately 7.8 acres of impervious area, while Alternative B consists of approximately 9.4 acres of impervious area. Alternative A presents a reduction in the amount of new impervious area, and preservation of native vegetation and critical areas to the extent feasible, relative to Alternative B, and therefore Alternative A uses a site planning approach consistent with Low Impact Development (LID) principles. Alternative B would allow the County expanded use of the site but results in additional impervious area and stormwater runoff requiring treatment and detention.

The size, and number of stormwater facilities would vary between Alternatives A and B. Due to the wetland near the middle of the site in Alternative A, potentially separate stormwater facilities could be required for the western and eastern portions of the site. Stormwater pipes may not have adequate slope to drain from the western portion of the site around the wetland to the eastern portion, and therefore, separate enhanced runoff treatment and flow control facilities could be required. For Alternative B, it is assumed that the majority of the runoff will drain to one set of runoff treatment and flow control facilities.

A preliminary analysis of the stormwater facility sizing for Alternatives A and B is documented in the DRAFT Preliminary Stormwater Technical Memorandum, July, 2021. The preliminary sizes for the flow control facilities are based on an assumed live storage depth of approximately five feet of drop from the inlet to outlet of the detention facility.

The live storage depth is constrained by the outfall elevation of approximately 222 feet in elevation at the south side of the site. A minimum finished grade surface of approximately 230 feet in elevation is therefore required for stormwater to drain into catch basins and pipes, and be conveyed through runoff treatment and a detention facility prior to the outfall. Fill from excavated native material or imported material would be required to achieve roughly the 230 feet elevation at the lower end of the site. Options for reducing the required grade over the vault include a lower live storage depth (and increased vault area), or utilizing some space on site for open ponds or stormwater wetlands.

Another alternative to raising the grade with fill would be to evaluate constructing a stormwater trunkline extending off site far enough to connect at a lower elevation, thereby lowering the outfall elevation and allowing the detention vault live storage to operate at a lower elevation. Compliance with critical areas ordinances, potential easement acquisition, and permitting would need to be evaluated as a part of this option for a stormwater trunkline.

The preliminary cost estimate of the above facilities is of negligible difference, and is therefore not included in the relative cost estimate of Appendix F.

Structural The buildings will be steel framed structures with concrete spread footing foundations; this framing style will provide open space in the garage bays without the need for columns. Foundations will extend approximately two feet below grade to meet frost depth. The floors will be concrete slab on grade, with a thickened slab at the garage bays. The infill walls will be light gauge steel framing members. The lateral force resisting system for both wind and seismic will be steel moment frames and/or tension only cross ties.

The structural systems for both alternatives will be similar to each other and no appreciable cost difference will exist between the structural elements for either option.

Retaining walls in fill areas will utilize gravity walls (rockery or block) for walls less than six feet overall height; taller walls will utilize mechanically stabilized earth walls with block or rockery facing to match the shorter walls. These two wall types are the most economical options for these ranges of wall heights, and provide some flexibility in choosing the final appearance of the wall.

Geotechnical Engineering (contributed by Aspect Consulting) The site conditions are conducive to the grading, structure support, roadways and pavements, and retaining walls proposed by both alternatives. Re-use of the on-site soil for structural fill will require dry weather, careful control of moisture, and likely moisture conditioning (drying). Structures that span areas

k:\project\33300\33305\projectdocs\site planning\20210801 alternatives analysis tech memo.docx North Kitsap Service Center Page 9 of 11 Alternative Analysis — DRAFT August 4, 2021

of cut and fill will require foundation subgrade preparation strategies like fill cushions or over-excavation and replacement to reduce the risk of differential settlement.

Alternative B will require the placement of fill in the Wetland C depression. At the time of construction, clearing and grubbing will need to be performed, and the wetland area soils should be inspected to understand if the over-excavation of unsuitable soils is necessary prior to placing structural fill for the support of overlying pavements and structures. Otherwise, there are no other significant differences between Alternatives A and B from a geotechnical perspective.

Mechanical and Electrical Engineering (contributed by P2S) P2S is responsible for designing the Vehicle Wash and Fuel Station, as well as mechanical/electrical/ communication systems within the Moderate Risk Waste Facility and Administration and Crew Building/Vehicle Maintenance Shop. Therefore, there are no significant advantages from an M/E standpoint of one alternative over another, other than better vehicle maneuverability of Alternative B as addressed in the above “Vehicle Maneuverability” sub-section.

On-site Sewer System (OSS) (contributed by Allied Design) Both alternatives have the Moderate Risk Waste Facility and Administration and Crew Building/Vehicle Maintenance shop in the same locations. It is assumed because of their locations on opposite sides of the site, that it is more cost effective to have separate OSS facilities for each building, and sufficient space exists to place them between the paved areas and the critical area buffers. The final locations and layout will be determined in the subsequent 30% design effort. There are no significant differences between Alternatives A and B from an OSS perspective.

Environmental and Permitting Alternative A largely avoids impacts to Wetland C, streams and associated buffers on site. Minor buffer impacts may require buffer averaging as allowed per Kitsap County Code (KCC) Title 19 (Critical Areas Ordinance). Buffer averaging allows a portion of stream or wetland buffer to be reduced to accommodate site development while expanding other portions of the buffer that result in no net decrease in total buffer area. A critical area tract or similar covenant would need to be filed during the land use approval process to document the amended buffer boundaries in perpetuity. Alternative A maximizes protection of regulated environmental areas, and as such would be expected to have a minimal environmental review and compliance process with Kitsap County Department of Community Development.

Alternative B includes filling Wetland C, a forested wetland centrally located on the property. It is recommended that an Approved Jurisdictional Determination be submitted to the United States Army Corps of Engineers (USACE) to determine if Wetland C is regulated under the federal Clean Water Act (CWA). If Wetland C is regulated under the CWA then impacts to it will require authorization from the USACE, including wetland mitigation. Regardless of whether the USACE does or does not regulate Wetland C, it is regulated under KCC Title 19 and impacts to it will require a variance process and compensatory wetland mitigation per KCC 19.200.230. Off-site mitigation options include the use of a mitigation bank or in-lieu fee program. The Hood Canal Coordinating Council (HCCC) In-Lieu Fee Program has credits available to offset the wetland impacts for the proposed project. In consultation with HCCC staff, cost estimates of these credit purchases vary from $467,968 to $923,968 as shown in the tables below.

The main cost difference is a result of different temporal loss factors applied to the credit purchase. The HCCC In Lieu Fee Program has identified a wetland restoration site in the Gamble Creek watershed that is near the anticipated project impacts, which makes purchase of the credits highly favorable by regulatory agencies. However, the construction of the HCCC’s restoration site has not begun and currently does not have a construction schedule. If credits are purchased before the HCCC goes to construction, then the mitigation for the impacts to Wetland C on site will be considered “delayed,” and thus have a multiplier of five as shown. If project impacts to Wetland C are “concurrent” with construction of the HCCC wetland restoration site, then fewer credits would have to be purchased and thus a lower wetland mitigation cost. Per personal communication with Patty Munchak at the HCCC In Lieu Fee

k:\project\33300\33305\projectdocs\site planning\20210801 alternatives analysis tech memo.docx North Kitsap Service Center Page 11 of 11 Alternative Analysis — DRAFT August 4, 2021

Program, the HCCC’s Gamble Creek restoration site is planned for construction in the next two years. Approval of the mitigation plan would be required by the federal, state, and local agencies.

Multi-criteria Analysis To assist the Otak team with providing a recommendation, and to aid the County in making a decision on the preferred site alternative, the Multi-criteria Design Matrix of Appendix E was prepared. It summarizes qualitative, and relative cost estimate quantitative, advantages and challenges of each alternative. Refer to the Relative Cost Estimate of Appendix F for the estimate range shown in the cost criteria in the matrix.

Recommendation Otak recommends Alternative A. Now that the program elements have been validated, the critical areas confirmed, the site planning has been performed to place program elements and perform vehicle wheelpath simulation modelling to test vehicle maneuverability, it appears that Alternative A has no apparent significant flaws, and has distinct cost, environmental, and community support advantages.

To: Jacques Dean, Kitsap County From: Cristina Haworth, AICP; Jeff Massie, PE Copies: File Date: August 1, 2021 Subject: Expected Kitsap County Population Growth and Transportation Facilities Demand Project No.: 33305

This memorandum evaluates Kitsap County population growth projections to address concerns that the North Kitsap Service Center (NKSC) program will adequately accommodate future service level demands. The NKSC is a proposed road maintenance and operations shop with collocated household hazardous (moderate risk) waste collection facility. The road shop portion should provide adequate space for materials and equipment storage, building space for staff needs, and vehicle and equipment parking for anticipated future service needs.

Background There is some inherent difficulty when anticipating changes in future road maintenance needs. Assets (e.g., bridges, lane miles of pavement, striping and signage, etc.) typically increase over time due to population growth, associated land development and densification, and transportation level-of-service concurrency requirements. As development within Kitsap County increases, however, ownership of many assets will be transferred to municipalities through future annexations of designated urban growth areas that are currently unincorporated.1

This memo analyzes Kitsap County’s adopted Comprehensive Plan to provide perspective on the adequacy of the North Kitsap Service Center site and building program and its ability to serve potential future growth. This memo does not address any possible future agreements between municipalities to have the County maintain and operate their transportation assets.

Public Works Projected Staff Growth The 2016 Kitsap County Public Works Strategic Facilities Plan developed a site and building program in 2016 and 2017. This formed the basis for establishing minimum criteria for facility sizing in preliminary planning scenarios. The Plan assumes very little growth in maintenance needs. The Plan’s preliminary space program assumes a 15 percent growth for full-time operations crew and no growth in administrative or supervisory staff.

Programming for the Moderate Risk Waste Facility for current and anticipated waste streams is covered by the July 14, 2021 Final Kitsap County HHW Programming Report prepared by Special Waste Associates.

Expected Kitsap County Population Growth and Transportation Facilities Demand The 2016 Kitsap County Comprehensive Plan projects the County to grow to 331,571 residents by 2036.2 The 2017 estimate published by the Washington Office of Financial Management (OFM) predicts growth to between

1 Washington’s Growth Management Act requires growth to occur at an urban density only inside the Urban Growth Boundary. The Urban Growth Boundary contains incorporated cities and designated Urban Growth Areas that will eventually be annexed. Growth outside the Urban Growth Boundary will occur at a rural level consistent with existing zoning standards. 2 This is assumed to be the high projection series population estimate published by OFM in 2012. k:\project\33300\33305\projectdocs\site planning\alt analysis tech memo figures and appendices\appendix c_expected kitsap county population growth and transp facilites demand memo july 26, 2021 by otak, inc.docx

315,437 and 400,231 people by 2036.3 This rapid growth is expected to be concentrated in existing incorporated areas or designated urban growth areas to be annexed based on the Kitsap County future land use map and zoning map.

Numeric Total Percent Avg. Annual Year Population Change Change Growth Rate 2010 (baseline) 251,133 2011 (est.) 253,900 2,767 1% 1% 2021 (est.) 275,600 21,700 9% 1% 2036 (est.) 315,437-400,231 39,837-124,631 14%-45% 1%-2%

The Comprehensive Plan estimates that approximately 23 percent of the projected growth will live in unincorporated areas outside of the urban growth boundary. Applied to the current OFM projections, the County can expect population growth in unincorporated areas of approximately 9,163 to 28,666 new people by 2036. Based on Census-estimated 2.48 persons per household, this translates to 3,684 to 11,559 new housing units in all of unincorporated Kitsap County.

Unincorporated Kitsap County is intended to be developed at a rural level of density, typically between one unit per five acres and one unit per 40 acres,4 indicating that development and associated traffic impacts will be relatively low. Urban levels of density are anticipated in existing incorporated jurisdictions and adjacent designated urban growth areas. For the purposes of planning for roadway maintenance and operations, roadways in incorporated cities or urban growth areas are assumed to be maintained by those jurisdictions. Based on projected population growth, estimated number of housing units, allowable density in unincorporated Kitsap County, and the current Capital Improvement Plan/Transportation Improvement Plan documents, this memo assumes no significant expansion of the roadway network will occur. Ongoing maintenance of the existing network may increase due to a greater volume of traffic and associated wear and tear in the North District due to increased development.

System Deficiencies and Planned Improvements Kitsap County adopts level of service (LOS) standards for its roadways and intersections and is responsible for maintaining its roadways and intersections at those LOS standards. The County allows up to 15 percent of lane- miles to temporarily exceed LOS standards for determining concurrency. The County assessed its roadways in 2015 and determined that the North County region has four road sections totaling 7.9 lane-miles that are deficient from the adopted LOS standards. Deficiencies are in WSDOT rights-of-way. After implementing planned transportation improvements, Kitsap County will still have 7.2 lane-miles of deficient roadways in the North County region in 2036, and deficiencies remain in WSDOT rights-of-way. No significant expansions in the roadway network are planned.

Summary By 2036, unincorporated Kitsap County will remain rural in population density. The number of road assets are not anticipated to increase significantly and may be offset by municipality annexations. It is anticipated that the programming prepared by TCF Architects, and program validation prepared by Otak, is adequate to address growth needs through 2036 and indefinitely beyond.

3 These estimates are from the moderate and high projection series. Kitsap County surpassed the low projection series and that is not considered an appropriate projection. 4 Limited exceptions apply in specific Rural Village areas. k:\project\33300\33305\projectdocs\site planning\alt analysis tech memo figures and appendices\appendix c_expected kitsap county population growth and transp facilites demand memo july 26, 2021 by otak, inc.docx Appendix D Existing HHWC and Road Maintenance Facilities and North Kitsap Service Center, April 22, 2021 Field Trip Notes, Otak, Inc.

Field Trip Project No.: 33305 Project Name: North Kitsap Service Center Meeting Date: April 22, 2021 Meeting Time: 9:00 AM to 4:00 PM Locations: Stop 1: 5551 SW Imperial Way, Bremerton Stop 2: 2339 SE Cedar Road, Port Orchard Stop 3: 301 NE Bernt Road, Poulsbo Stop 4: 2300 Bond Road NE, Poulsbo Attendees: Kitsap County: Jacques Dean, Rick Gilbert, Chris Piercy ,Keith Swearingen, Frank Hiller, Dave Myrick Otak: Jeff Massie, Mark Shelby, Michael Payne, Liz Wertz, Sierra Carson, Cristina Haworth, Dave Stewart, Jeff Gray, Lori McFarland Special Waste Associates: David Nightingale P2S: Akshay Prabhu

Stop 1 - 5551 SW Imperial Way, Bremerton; HHW moderate risk waste facility ▪ Site is .27 acre and was opened in 1996 serving 4,000 customers a year, currently serving 10,000 per year. Site mostly serves individual homeowners and some small business waste is accepted. ▪ Operates with a staff of 5, hours are 10-4 Thurs/Fri/Sat, new facility scheduling may be offset days. ▪ Currently accepting corrosive and flammable and toxic substances, paint, batteries, fluorescent bulbs, etc. WSP takes all explosives that inadvertently make it through screening.. WA State Department of Health takes radioactive material that also bypass screening. ▪ A new recycling program is launching 7/1, resulting in the removal of the paint crusher. A crusher will likely not be included in new site ▪ Currently the operation is 3,900 Sq Feet. A larger space is necessary with additional indoor/covered storage required to maintain standard operations and flow. ▪ Adjacent or connected Re-Use shed is required, easy staff access and within line of sight is required ▪ Need a semi-truck loading dock to accommodate a max of 53’ truck/trailer combinations ▪ Desire lift gate at loading dock for business and residential drop-off in case large pallet loading/offloading is needed. ▪ Desire to maintain an overhang/protected drive through 2 lane (minimum) drop off location and add a wind screen cover for awning. Current width of pavement works well, no sidewalk or striping. Bollards will be necessary as well as a manually controlled remote traffic arm. ▪ Wind and wind-blown-rain protection should be provided. ▪ Current spill containment is a curb and drain. Could potentially use curb/swale/drain. The opportunity for spill is limited to 55 gallon drums as that is max size. But since the team controls the flow of vehicles someone is always present so even then the entire drum would not have enough time to empty fully ▪ Break area should connect to the outdoors

Inside Facility: ▪ Staff intakes items on carts, sorts and processes

▪ A scale is currently by the front sorting area.. Current scale is a trip hazard, staff wants something more integrated flush-mounted in the floor. Scale location could be moved to the storage areas, or adjacent to them. ▪ A more ergonomically located fume hood is desired, used for identification of unknown substances ▪ Flammable liquid processing involves the most routine potential exposure contact for staff. It is mitigated by ventilation and respiratory protection. ▪ Some spot ventilation is currently insufficient ▪ Fugitive dust lab packing operations is a new system to collect dust and puts absorbents into drums ▪ LED lighting installed in 2009/2010 via federal project works very well. Natural light should be factored into new facility design. ▪ Fire suppression system is a dry chemical powder system which is very expensive to maintain ▪ Explore the idea of the entire facility being all sprinkler and having location to store water reactive chemicals, and limited dry chemical use - review code impact ▪ Floors are double coated epoxy impermeable surface which is very expensive to maintain and update. Best practice should be a coated floor with secondary containment in specific areas where it’s needed. Need a cleanable concrete floor with coating ▪ Area for Reuse storage and sorting. No pesticides or toxic items stored, just motor oil, paint, less toxic cleaners and misc. aerosols for customers to pick up at no charge. ▪ Flammable bulking room (5’x10’) needs to be at least twice as large, maybe three times. Need additional storage of bulk materials, drum staging. Room has/needs enhanced ventilation and LEL meter with visual and audible alarm ▪ Fugitive Dust system may need an upgrade. Mezzanine storage is needed – current space is difficult to access ▪ Roll up doors separate each area of the facility, in an emergency they automatically close. There is a trench/sunk drain to capture any sprinkler liquids and they go to an underground vault outside which gets cleaned and pumped/serviced ▪ Need doors wide enough for easier movement (with drums) in and out ▪ Site could use a smaller dumpster, a 10 yard is good ▪ Facility should have additional storage so empty 55 gallon drums don’t need to be stored outside. This area should be protected from rain (snow). At a minimum empty drum storage could be outdoors but under cover. ▪ Facility should have security and visual fencing around outdoor storage ▪ Current office is for 4 work stations – it’s very cramped, should probably be double in size ▪ Break room should be larger and adjacent to outdoor area for staff. Staff all take lunch at the same time current break room is too small. Break area should connect to the outdoors ▪ Emergency shower is located in the middle of operational area. Shower should have privacy curtains and be very easily accessible to facility operations. It should also be plumbed for warm water and in compliance with OSHA/WISHA regulations for GPM water flow. ▪ Single unisex bathroom does not connect well to shower/ dressing/ locker area. ▪ Some of the office space isn’t in compliance with ADA regulations, so this should be corrected. Task – review and incorporate best practice recommendations from Special Waste

Admin Annex – Kitsap County Public Works Annex ▪ Use similar layout, where facility buildings and covered parking is surrounded by trees and that the exterior design integrates well with surroundings in color and style ▪ New location will be Road shop so needs space for 3-4 offices for supervisors. Needs a crew room/multipurpose room for meetings, breaks. Restroom and locker room all required ▪ Need street sweepers parked indoors as water is stored on board; don’t want it to freeze/ ▪ Need concrete stem walls and/or bollards in the bays ▪ Mezzanine storage is very desirable to minimize building footprint, and to maximize space ▪ As much natural light as possible is desired, high windows or skylights

Stop 2 - 2339 SE Cedar Road, Port Orchard; South Shop

▪ This location is in the best shape of all the facilities. Sits on 25 acres, only ½ is in use ▪ Wash bay, self-contained loop system, pressure washier. Vactor trucks sucks out sump weekly ▪ Salt bins under spring structures works well, and are covered by a tarp on the end to eliminate rain from forming a crust on stockpile; should be located away from vehicle storage and equipment as much as practical as its highly corrosive; orient the cover opening to the north, if possible, to limit inclement weather impact ▪ Additional bins are necessary for a total of 10-12 bins which are typically 20’x20’ ▪ Area for stock piles (aside from bins) is needed as well ▪ Need additional barn storage for covered parking of vehicles ▪ Racks for sanders with ladder/stairs and a catwalk is necessary to load. Currently staff use a ladder across the top which is very dangerous. An easily accessible system is needed ▪ Site lacks a strategic flow of access ▪ Fuel station is in a flow blocking location. A covered fuel station is desired, would need a height to allow for largest type of trucks through; if the North Road Shop fuel station has a canopy, there will be a desire for the other shops to follow suit, so it is not a definitive requirement at this time ▪ Flow through maintenance bays for are necessary, at least ½ of all bays should be flow through ▪ Overhead (gantry) crane access engine side, reaching across all bays to at least the front half depth, but must NOT prohibit us of bay as a vehicle repair station. ▪ A bay could be used with built-it storage racks to help with inventory control ▪ Needs to have capacity to store vehicles that rotate around the county’s various locations throughout the year ▪ Chip spreader & paving machines needs cover (not heated) due to abundance of hydraulic hoses ▪ Grinder is sensitive to heat. Roller and sweepers need a covered/ heated space ▪ A cantilevered overhang is highly desirable where it makes design sense along buildings; charging stations may be a good application for cantilevered parking ▪ Solar infrastructure on top of structures could be an option and could support future requirements. There may be grant money; since the County is not taxed, they are not eligible for federal tax credit ▪ Need to at least add electrical conduits for future electric vehicle charging; Keith stated that the conversion of light duty vehicles to electric will be implemented quickly once in production (likely 2022) following other vehicles; There are 3 office spaces and 1 cubicle and currently needs more office space ▪ Need to ensure new space has good internet, Wi-Fi and computer/tablets for staff to do timecards and mandatory trainings; currently all timesheet entries are on 3 standing stations adjacent to each other ▪ All county sheriff vehicles are upfitted at this location but all locations should expect to see sheriff vehicles onsite ▪ KONI Lift required at new site, fits around tires, automatically adjusts, works off charge; they are portable, requiring no flush or surface mounting to floor ▪ Single, 4-post auto lift needed for truck maintenance (fleet pickups) in single bay, drive thru not required ▪ No service pit’s are required ▪ Need air and electricity for every 2 bays ▪ Oils and fluids for every 4 bays ▪ Need a plug just inside the door for access to power equipment if people pull up an the bays are full ▪ Desire power for welding outside of maintenance bay doors for flexibility ▪ Emergency generator required as this is emergency operation center ▪ Grader. Loader, dump truck - need 7 full time, 1 is floater ▪ Vehicles on site for: Gravel, mower, paver, bridge work, chip spreader, roller, sweeper, push, grader, loader, dump

Stop 3: 301 NE Bernt Road, Poulsbo Feedback on overall flow od site: ▪ Problem - limited buildings and space so things are put wherever there us space regardless of functionality ▪ One truck in one truck out is all that can be accommodated at this location ▪ Not having to wind through areas with large vehicles would be ideal ▪ Need a wide berth to drive through, load/unload, hit fuel island along the route ▪ Ingress/egrees is important.

▪ Referring to N Kitsap Service Center conceptual site layout, talked about rotating HHW facility 90 degrees to separate public access to it from road operations facility access to create better flow and less conflict ▪ Allowing 53’ truck/trailers combinations within footprint of HHW Facility would require lots of pavement space to maneuver. Discussed the potential internal gate to allow HHW Facility delivery truck/trailers to maneuver in road operations yard to provide egress maneuverability to reduce foot print for HHW facility.

Grouping of materials ▪ Materials that can’t be outside: Glass beads for paint striping in 4’x4’ totes, 25 each, not stackable; cold mix pavement and Salt in non-corrosive covered shelters; paint that has to be placed under cover, away from direct sunlight - bay(s) under vehicle canopy would be sufficient. ▪ Snow plowing and sanding operations: sand stockpiles are located on the west end of the parcel. Currently drivers drive though whole yard for loading and unloading materials; if there are broken down trucks they have to turn around;if Sheriff vehicles are fueling they can’t pass through; drivers can’t get in and out to just get sand and move out; roughly half the trucks will go each direction. ▪ Rename Dirty Ops in describing these uses in project development to Bulk Ops to avoid possible negative connotation ▪ Area of stockpiling. Typical bins are 20x20 and uncovered. Is there a need to stockpile more than that? Just using additional bins (asphalt grindings, sand) Salt needs to be stored away from all equipment. ▪ Guardrail parts. (15 units that have different part numbers, stocked and stacked) Jacques would like to reference the Pierce County facility has allocated bays for within the covered vehicle canopy for these types of materials, including erosion control products and pipe are placed storage racks and shelves are built into the structure; i ▪ Drainage parts – grates, catch basins taking up a fairly large area. 20’ sections of pipe (seasonal storage for emergent projects) ▪ Only the brine machine under cover, where employees operate; the brine storage tank does not need to be placed under cover.

▪ Designing sand boxes with catwalks for safety for loading/unloading; there is a specific sequence of mounting sand boxes in dump truck beds that is shown on signs for staff.

Fleet maintenance ▪ 4 bays is good with additional cantilevered coverage ▪ Parking is generally placed after space and building placement as an afterthought ▪ Being able to have multi directional flow is essential in two of the four bays ▪ Design the site to accommodate for low-boy and truck/pups, that will cover all other vehicles.

▪ TVac and grinder trucks are the largest turning radius (tractor low boy) - **Jacques provided turning radius map at beginning of project ▪ Employee parking can be up to 35 spots. Typically 21 Road employees and 1 mechanic, but in summer we have 8 additional employees. 2 sheriffs vehicles at all times, 1 DCD. ▪ Targeting 30 employees (future growth). This programming was based on 30 for future needs. ▪ Fuel and wash close together, separated and in a sequential line. Convenience of cleaning. (largest vehicle would be dump) Currently located about halfway in. Would be best to get it close to the daily workflow. Topping off vehicles is part of the daily tasks. Stacked side by side is not beneficial ▪ Need lots of efficient/bright overhead lighting over the Fleet Shop working area due to low light half of year.Automotive tire shop space is desired for tire storage and mounting equipment. 10x20 area moderate sized tire shop in fleet maintenance ▪ Additional insulation would be good ▪ Radiant floors (? Wishlist item) ▪ Rolling doors are currently 14’high by14’ tall; desire doors to be 16’ high; Need electric openers. If they are panel doors, strongly consider light panels for more natural light. ▪ As much natural light in the shop. Exposure on the top/sides. Super light or white ceilings and walls for mechanic areas. ▪ Floors need to slope to doors. Grates will be right in front of doors, unobstructed as in the winter its wet and need the water to move out ▪ Concrete floors – smooth solid finish (review slip resistance requirements)

Security ▪ Sliding gates ▪ Key card access ▪ Video inside and out, full coverage, and must pickup the fuel station (regulatory requirement for HHW Facility)

Other considerations: ▪ Summer time night paving – truck noise, dumping, hauling etc. Some sort of wall near /at bulk storage ▪ Potentially move admin building closer to residential areas and moving bulk storage further away. 53’ trailer need to accommodate 180 degree turn; 74’ design vehicle. See turning radius diagram.

▪ 3 very vocal neighbors on the northeast side of property line ▪ If the Sherriff’s is located onsite, it was stated it would need to potentially have access by public for filing reports, etc. If so, having the office located in the road operations administration office could be problematic due to security gates. Discussed the possibility of locating near or in the HHW facility (say on the 2nd floor) due to the public accessibility to the HHW facility.

Flip Chart Notes at noon Work Session: ▪ Site Planning - Generic site concept and test to fit scheme. Building blocks for NE site concept on PW Property ▪ Site Issues o Stream 150’ buffer o Wetlands – one in middle of property and one along stream ▪ Feedback on site concept: o Ingress/egress is a major consideration o Avoid confined areas o Avoid winding routes o Sequence stops in order of operations (enter, pick up trailer, load materials, fuel up, etc) o Bond Road traffic is a major challenge. Every 35 minute rush cycles from ferry riders o Separate ingress/egress required between HHW & Road Operations facilities. HHW Facility must accommodate semi truck/trailer deliveries. ▪ Materials o Salt stored outside covered (non corrosive) o Glass beads stored inside o Cold mix stored outside and covered o Other materials stored outside and uncovered ▪ On site congestion is an issue with current site ▪ Minor storage for catch basins and guard rails; rail components could be stored on a rack system. ▪ Parking for up to 35 vehicles (21 employees, temp summer employees, sheriff, DCD, and future growth to 30 employees ▪ Snow falling/sliding from roofs onto staff at exterior doors has never been an issue; this however was an issue at the new Pierce Co. facility. Awning over sidewalk adjacent to building was damaged by snow fall. ▪ Tire shop 10x20 is desirable ▪ Insulated shop desirable. Radiant floors? ▪ Rolling doors must be at least 14’ tall, preferably 16’ ▪ Electric door openers are desirable ▪ Glazing in doors/. High walls could be an option for natural light ▪ Natural light is best, white/light walls ceiling ▪ Buildings must drain unobstructed, and be smooth and cleanable ▪ Fuels and wash separated for convenience. No u turns or side by side station, should be linear ▪ Consider a small decant holding facility; the decant ultimate disposal is at a wastewater treatment plant ▪ Sliding gates, key cards, video surveyance inside and out ▪ HHW to cover drums or store inside ▪ Consider showcasing an educational opportunity for natural features, visible from highway. Stormwater or aesthetic ▪

Stop 4: 2300 Bond Road NE, Poulsbo

Jeff Massie started the discussion • The geotechnical investigations are completed; the borings and test pits show shallow topsoils, with Vashon Till to depths exceeding the 50’ deep borings • The site has recently been mapped; Mark displayed the topo map, which did not clearly show the critical areas and their buffers boundaries, however all trees within critical areas have been located – if there is a tag on a tree, that means it’s in the critical area or buffer

Jeff Gray led the discussion regarding critical areas: ▪ 2015 ELS critical areas report commissioned by previous property owner has been field verified by Otak. A subsequent critical areas report which references ELS report will be prepared. ▪ Wetland C should not be regulated by the U.S. Army Corps of Engineers as it is not hydraulically connected to a water of the state. ▪ The onsite stream has been upgraded to a fish bearing stream and buffer updated to 150’; there are no hydraulic jumps or other elevation impediments within the reach which was traced hundreds of yards downstream ▪ Discussed strategy of possibly impacting Wetland C and buffers if site planning shows that it may be impractical to avoid impacts. o There are not known wetland banks in which the County could simply purchase credits to mitigate impacts o Would like to have discussions with County departments about the possibility of mitigating wetland impacts on County property; enhancing or creating wetlands on Parks and Recreation-owned properties is viable – Otak did that on an Island County project o On the adjacent parcel, the property owner has committed to daylighting the stream as a condition of interior road construction after negotiating a reduced buffer; perhaps an arrangement could be made to enhance the stream or impound additional flow; mitigating near the impacts has advantages o Jacques asked about the possibility of mitigating on-site; Jeff Gray replied that it’s difficult to justify removing forest in the 150’ stream buffer in order to do this.

Cristina Haworth lead the discussion regarding land use code • Discussed building setback requirements around property; including enhanced setbacks on the NE side of property where residential land uses abut to this use in the Local Area of More Intense Rural Development (LAMRID). • General discussion about landscaping requirements. • There was discussion regarding possible Wetland C impacts, and associated variance requirements. o Cristina said they may be administratively issued, or possibly required a public process such as a hearing. o Under such a scenario, go ahead and issue SEPA threshold determination following 30% design, then go through variance process during County land use/construction permitting process.

Dave Stewart led the discussion regarding onsite stormwater • Code requires evaluating flow control solutions: o Dispersion into forested land – generally requires to be spread laterally, a minimum of 100’ from streams; it may be able to be fit in 150’ stream buffer, but need to evaluate flow path length based on size of impervious area. o Also can/need to evaluate infiltration; as the site is underlain with Vashon Till with low permeability, this may not be feasible o If dispersion or infiltration are not viable, will look at more conventional flow control such as below grade vaults, or open ponds

• Water quality treatment will likely need to be enhanced; will consider proprietary filter vaults or biofiltration • There was some discussion should Wetland C need to be impacted, it could be converted to a stormwater pond; if it was to be lost for ecological function, a reasonable alternative use would be to impound water, possibly provide opportunity for educational interpretive signage, and possibly provide a boundary between public HHW facility and staff accessed Road Operations facility

The team walked into the site to the central area wetland

This summary supplements the Notkin (a P2S Company) June 3, 2021 Field Investigation Report.

Office Building • The building is primarily a steel framed structure with board form concrete based, window wall and horizontal corrugated metal above (not ideal as it holds dust and dirt) sun shades and a lower canopy system has been damaged • The foyer is dramatic including polished concrete floors, exterior siding, and overhead art • Interior materials are: open metal staircases with perf riser, perf metal ceiling, concrete floor, metal mesh ceiling panels, some gyp board walls/ soffits and frosted glass window wall system at offices • Central corridor with offices and conference areas with operable windows and available light • Sustainable Design interpretive signage greets visitors – project is LEED 2.1 Silver • Meeting rooms have mobile furniture, stacking chairs LED lighting, small kitchenettes and movable partitions to expand meeting spaces, open ceilings • The rain gear drying room looks like an oversized toilet stall with a single rod to support rainwear; good concept, but could have a better rack system • The locker room is unisex, as are at least some of the bathrooms; if staff need to change clothes, they need to go to the restrooms – open ceiling, bolted benches, vented locker, available light, boot drier on concrete pedestal • Laundry facilities are available to staff – 1 washer/ 3 driers and mop sink • Vending machines outside restroom area • Confirmed the workout room upstairs goes mostly unused primarily due to physical nature of the jobs that operate out of the facility • (2) boot cleaning areas with a hose and metal grate are located outside at locker room entrance for washing boots – boot scraper, handrail • Entries have metal walk-off matts and key entry

Central Maintenance Building: Building C • Buildings are open metal structures with white metal (open) ceilings, standing seam metal roof, smooth concrete floors with area striping. There is a 6’ CMU base with horizontal corrugated metal siding above and some gyp infill walls. Metal doors are used thorough-out with lower half kickplate in many places • Mezzanine above (storage?) • Supplies (e.g. guardrail PT wood for railing repairs) are covered at North end • Equipment is checked out from secure structures with roll up doors - hand held power equipment (e.g. string trimmers, chain saws) are accessible via an internal drive aisle through the middle of the structure • Tool repair is in the secure room. Manual checkout with tag system is used to track and maintain tools. k:\project\33300\33305\admin\meetings\2021-06-02_pierce co central maint facility field trip notes - mjp.docx Pierce County Central Maintenance Facility Field Trip Summary June 2, 2021

• Open bays are used for some repair and projects • Metals storage rack could be useful at open bays • Eye wash, mop sink with metal grate station is located near tool checkout • Compressed air and power outlets are provided at each perimeter column (East side)

East Maintenance Buildings: • The plows are in covered parking as are the sand spreaders, accessible by overhead rail cranes; dump truck sand bed inserts are stored on uncovered racks elsewhere • Small gantry crane provided at the inside of each parking stall for installing equipment • Tool boxes flank the center aisle

Enclosed heated parking - South end of the building • Paving and BST equipment, plus vac trucks and street sweepers are in the heated parking on the; the windows were covered to help with security • Additional storage and glass beads are in open bays • Trench drain at center of each drive thru bay • Extended canopy at each drive bay at West side

Salt Storage: • Fabric covered steel frame mounted to concrete foundation; the bins are lined with ecology blocks presumably to help protect the structure

Fuel Tank: • Above ground

Rock, sand and gravel: • Is on-site

Wash Rack: • It has a raised steel walkway which reportedly is rarely used; there have been issues with water freezing in the pipes • An enclosed wash bay is located between fuel and the open wash rack – it was mentioned that the room needed cleaning after a vehicle wash.

Fuel Dispensing: • The tanks are located outdoors • Fuel pumps are located under cover – this was connected to the wash rack

Fleet Maintenance Building: Building B • There is a 10 ton north/south running Gantry crane on the west bay • The fabrication shop has a jib crane, which does not get used that often • The welding exhaust system is inadequate, possibly limited in size due to the space required by the jib crane • The welding table is very useful; the lathe not so much • A sturdy metals storage rack is very useful • The vehicle exhaust system between maintenance stalls works well, it’s located on the same rack as the oil dispensary hoses (every 2 bays) It was suggested to relocate these to the head of the stall where pull through stalls are not needed • One fixed car lift was in one bay • Utility sink with metal grate was provided at about (3) locations • Trench drains were located inside each OH door • Mezzanine area is used for storage, but may be underutilized and the gantry crane does not have good access • Mechanic tool boxes tend to be very large; each station has computer work station

Field Investigation Report

Date of Visit: June 2, 2021 Visit No. one Time of Visit: Noon Project: Kitsap County North Road Maintenance Facility Weather: Sunny Notkin/P2S Project No.: 2021-0086 Attendees: Darren Schwend

Description of Work Performed:

Darren Schwend toured the Pierce County Road Maintenance Facility to observe the best practices that can be applied to the Kitsap County Facility.

I. Site Observations

Office building: 1. The locker room is equipped with integral boot dryers below the lockers that are supplied with ventilation air from the HVAC system. The boot dryers consist of 1-inch hoses blowing air. 2. A drying room is equipped with hander racks and sealed floor for drying wet gear in the open air. 3. The building is equipped with a VAV HVAC system. 4. Walk way roof damaged by falling snow.

Maintenance building: 1. There is room for improvement in the storage and office heating and cooling system. 2. Natural lighting through high bay windows is a favorite feature. 3. Radiant heaters between bay doors provide heat. 4. The lighting is troublesome, and the operators would prefer LED. 5. The air compressor is large rotary screw which provides reliable service but it’s complex and requires service from select vendors. 6. The ventilation system for offices is heating only and seems to pull in dust and dirt from the shop. They recommend enhanced filtration and cooling for offices in a new building. 7. Centrally located part storage would limit the time walking for parts. 8. The bulk lubricant storage is adequate, but they could have used even more space. 9. The operators recommend siting the maintenance building to maximize natural ventilation. 10. They like the carbon monoxide exhaust reels from the floor because they’re accessible and simple to operate as compared to an overhead system. 11. They would have preferred lube guns between every other maintenance bay for better access. 12. Circuit labeling for electrical outlets would be a huge improvement. There are no labels in the facility. 13. The mechanics like the facility but could use more room to maneuver trucks with trailers.

Wash Rack: 1. Ensure the pressure washers or washing system is automated to prevent inadvertent damage from users. There are gas fired steam pressure washers that can overhead and are damaged if not shut down properly. 2. The facility does not recirculate water. Kitsap County North Road Maintenance Facility Field Investigation Report-June 3, 2021 Page 2 of 3

3. Central vacuum system works well.

Fuel dispensing: 1. The bulk fuel tanks have condensation issues that may be preventable if they were covered or indoors. 2. Fuel tanks are corroding, and staff suggested a roof to limit rust and corrosion. 3. We should include a bulk DEF (Diesel Exhaust Fluid) tank.

Covered parking areas: 1. Uninsulated roof will condense water below the roof and essentially rain under the enclosure at times. 2. Birds nest in the structure. Nets or other prevention is recommended.

Rainwater capture: 1. Rainwater used for toilet flushing. 2. Stormwater capture used for water in sweeper trucks and tanker trucks for dust control.
