Municipal Projects
Swinomish Roundabout Extension–Swinomish Indian Reservation, La Conner, WA
Jepson is currently fast-tracking the civil road improvements design for a roundabout extension south of the Swinomish Casino. Improvements include roundabout widening and street improvements extending an existing access road approximately 2000 feet. Stormwater improvements include water quality treatment using a constructed wetland system, road grading, coordination with various utility companies, and permitting coordination.
Southwest Ferndale Regional Stormwater Management Facility–Ferndale, WA
Jepson is currently working with the City of Ferndale on the first of seven proposed regional stormwater detention facilities. This regional drainage facility will be approximately 23 ac-ft in size and is being designed to meet State Dam Safety Guidelines. The scope of work includes a watershed analysis, conveyance route alignment identification, topographic and boundary surveying, full construction documents, specifications, and engineer’s estimates.
Kendall Elementary School Civil Design–Kendall, WA
Jepson performed full surveying and civil improvement designs for the Kendall Elementary School. Improvements included school siting, ball field design, utility infrastructure design, water system design, parking design, and DOT road channelization improvements.
Bellingham International Airport Alderwood & SW Detention Ponds–Bellingham, WA
Jepson is currently working with the Port of Bellingham to provide topographic mapping services for the Bellingham International Airport. The topographic mapping is needed to provide detailed information on the port’s current stormwater ponds capacities, downstream conveyance, and areas for expansion.
June Road Improvements–Bellingham, WA
Jepson is currently in the construction support phase of the June Road extension project, connecting Kellogg Road to Aldrich Road. Jepson was responsible for the mapping, civil engineering, stormwater design, environmental permitting, and coordination with the City of Bellingham and Whatcom County Public Works. The infrastructure design included full street width improvements including a 16” water main completing a water loop from Kellogg Road to Aldrich Road.
Aldrich Road Widening–Whatcom County, WA
Jepson is currently designing civil road improvements to widen Aldrich Road from Division Street to the new Aldrich School. The improvements include a ¾ street widening on the easterly side of the road. Our design team performed extensive wetland hydroperiod analyses and a downstream backwater analysis to determine the effects of using the large on-site wetland system to attenuate stormwater flows. Bio-retention cells were designed to provide enhanced water quality treatment prior to discharge to the wetlands. Roadway improvements provided a bike trail to accommodate this developing area of Whatcom County.
Oak Harbor High School Modernization–Oak Harbor, WA
Jepson provided construction staking services for the recently completed sports facilities and parking areas. Services included interpretation and clarification of construction documents, survey control network verification, construction staking, writing legal descriptions, and quality control.
