Parr Auto Group
Bremerton, WashingtonThe City of Bremerton placed this 11.4 acre residential site up for sale to have it re-developed into a commercial retail use. Westsound Engineering, Inc. provided a feasibility study and cost estimate for the Parr Auto Group during the bid preparation. After the successful purchase of the property, we prepared applications and obtain permits for site plan approval, special use permit, a special exemption, NPDES permit, WSDOT utility permit, and plan approval for on-site and off-site improvements.
Offsite improvements included mass grading of WSDOT right-of-way and City of Bremerton property to include a 700-foot long bioswale and a regional storm water detention pond. Oyster Bay Avenue was improved over a 1700-foot length with curb, gutter, sidewalk, street lighting, storm drainage, rockeries and left turn lane. The new centerline of construction alignment was coordinated with the City to maintain access to existing driveways and preserve existing utilities. The street profile was changed as much as 10 vertical feet. Approximately 900 feet of 66-inch diameter culvert was placed in the SR 3 right-of-way to improve storm drainage and eliminate grade hazards.
On-site improvements included over 120,000 cubic yards of earthwork and 23,000 square feet of retaining wall. Westsound Engineering, Inc. prepared design plans for site utility demolition, grading, drainage, sanitary sewer, water main, paving and striping. We also attended weekly owner meetings and subcontractor meetings prior to and during site construction to assure project success.

Little Bear Creek Culvert Replacement
Kitsap County, WashingtonTo improve the salmon passage for this creek, the double concrete box culvert was replaced with a pre-designed, pre-cast bridge system. WestSound Engineering, Inc. prepared the construction plans and notes to establish horizontal and vertical location details, temporary stream by-pass, and temporary erosion and sedimentation control for Kitsap County Surface and Storm Water Management Division.
Taree Drive Drainage Outfall
Kitsap County, WashingtonWestSound Engineering, Inc. prepared the construction plans to replace the existing outfall with high-density polyethylene pipe. The 60-foot vertical drop outfall to Appletree Cove, near Kingston, in Kitsap County had leaked and caused slope and pipe failure. Design included pipe sizing, anchoring, outlet dissipation, and a footbridge over the pipe.
Mosher Creek
Kitsap County, WashingtonThis 108-lot plat is located in the Mosher Creek drainage basin of central Kitsap County. WestSound Engineering provided engineering design, permit coordination, construction consultation, erosion control monitoring and coordinated subconsultants for land surveying, geotechnical evaluation, structural design, landscaping, construction testing and construction staking.
Unique features to this project include a footbridge that provides a pedestrian trail connection to both sides of the creek and utility crossings for sanitary sewer and storm drainage. Reinforced concrete wall and Keystone retaining walls, polyethylene liner and grasscrete pavers were utilized to provide the necessary storm detention pond volume in the limited space available. Wetland enhancement, stream buffer enhancement and a biofiltration swale are provided to protect water quality and improve the riparian zone for Mosher Creek.
Storm drainage analysis work included a flood plain analysis, an extended detention dry pond designed to meet the Washington State Department of Fish and Wildlife Hydraulic Project Approval and water quality mitigation conforming to the Washington State Department of Ecology Stormwater Management Manual for the Puget Sound Basin.
Illahee Creek Culvert Replacement
Kitsap County, WashingtonTo improve salmon passage and reduce sedimentation at the Illahee Road crossing for this creek, Kitsap County Surface and Storm Water Management Division determined that the existing twin 36-inch concrete culverts should be replaced. Westsound Engineering, Inc. was retained to prepared construction documents for a pre-designed, pre-cast bridge system. We evaluated flow at the 100-year and 500-year storm events to size the span and rise of the structure. Design also included log-weir check dams and stream channel re-alignment with armoring consisting of anchored logs, rip rap and vegetation.
Twelve Trees Business Park - Division 4
Kitsap County, WashingtonWatson Furniture Systems purchased 23 acres in this division to build a new manufacturing facility for their expanding business.

Design includes extension of road access and water system. Storm drainage improvements include a large roof downspout infiltration system, detention pond, and bioswale. Care in the analysis and design where require to avoid impacts to Jump Off Joe Creek and wetlands.
Station 64, Kitsap County Fire District No. 12
Kitsap County, WashingtonProvided conceptual design, construction cost estimating, construction documents and contract compliance as the civil engineer subconsultant to Rice Fergus Architects. Coordinated site layout, biofiltration and grading design revisions of the original design to reduce costs and improve access between the existing and proposed buildings. Improvements included fire beacons, grading, underground storm detention, biofiltration swale, water main extension, sanitary sewer pump station, oil/water separator for the building floor drainage, and utility services.
Reed’s Meadow
Kitsap County, WashingtonA conditional use permit was required for this 36-lot manufactured home park located in central Kitsap County. WestSound Engineering, Inc. coordinated the land surveying, traffic study, and preliminary landscape plan. Services included preparation of the site plan, land use applications and representation at the public hearing. Final design services included sanitary sewer lift station, water and sanitary sewer extensions, and road and grading design. Storm drainage included on-site detention pond, biofiltration and improvements at the Riddle Road culvert to mitigate developed drainage release volumes.
Belfair Valley Plaza
