Civil Engineering Projects

The Urban

The NorthStar Civil Engineering team worked with the developer to prepare on and offsite plans for this 36 unit student purpose project.  Project included a community center, 3 building types, carports, water feature, and gated entry points.  Entitlement included merger, special shading issues, and regular ARB approvals as well as Cal Trans involvement and PG&E relocations.

Fortna Road Improvements + Bridge Reconstruction

NorthStar’s objectives with this project were complete replacement of a structurally deficient bridge crossing over the Sutter Extension Water District Canal with a pre-cast concrete arch span bridge and roadway improvements for road approaches to bridges.

This project utilized NorthStar’s expertise in  topographic surveying, environmental clearances, hydraulic modeling, bridge design, roadway design, right-of-way services, and geotechnical investigations. As part of the Bridge Investment Credit, part of the CalTrans Local Assistance Highway Bridge Program, all submittals satisfied CalTrans requirements. A ConTech precast concrete bridge was utilized to cross the Canal. Existing roadway approaches were widened, and new roadway shoulders, as well as CalTrans approved safety guardrail barriers were added. This bridge is the only access to several residents and community outreach and coordination is key to project success. This project is also on an accelerated schedule to optimize construction bidding and allow for construction when there is no flow in the canal.

This project includes regulatory permitting and the preparation of both CEQA and NEPA documentation including an Initial Study/Mitigated Negative Declaration, Natural Environment Study, Biological Assessment, Wetland Delineation as well as a Section 404 Nationwide Permit, Section 401 Water Quality Certification, Streambed Alteration Agreement, and an Incidental Take Permit from CDFW for identified endangered species.

Neal Dow Elementary MPR + Classroom Buildings

DLR Group headed the design team for this 12,000 square foot multipurpose room, 8,000 square feet of new classrooms, 30,000 square feet of existing building moderation, and 66,000 square feet of new playground area. NorthStar prepared the site civil work which included modifying existing site improvements to accommodate the increased size of the building.

Portland Place Apartments

NorthStar prepared full architecture and engineering plans for this 8 unit market rate apartment project. This project included two building types (three story) with parking tucked under apartments. Entitlement required a planned development permit to reduce setbacks and an elevated finish floor to avoid flood zones. The project won awards for the use of corrugated metal siding and its modern look.

Manzanita Ave. Corridor Reconstruction

This project was a multi-phase high profile roadway reconstruction project on Chico’s main corridor along the eastern boundary of the city, east of Highway 99. The project consisted of four phases along 2.2 miles of roadway. The design process was initiated by the city in 2004; NorthStar began working on plans in 2005 with construction starting in 2008 and concluding in 2010. The NorthStar Environmental team continues to provide annual environmental monitoring services as part of the mitigation requirements. The project included:

  • 3 roundabouts on Manzanita Avenue at Vallombrosa Avenue, Hooker Oak Avenue, East Avenue/Wildwood Avenue/Eaton Road
  • 2 bridge widenings over Big Chico Creek Bridge and Lindo Channel
  • 1 new pedestrian bridge over Big Chico Creek
  • Culvert extensions at Dead Horse Slough

NorthStar’s civil engineering services included Plans, Specifications, and Estimate (PS&E) for full roadway improvement design incorporating significant traffic calming components, traffic signal design and modifications, complete topographic field surveys and base mapping as well as in-channel and Right-of-Way surveys, acquisition of high resolution aerial photography, storm drain and sewer design, and culvert extensions at Dead Horse Slough. NorthStar also provided Construction Management Services, including providing engineer’s estimates, prepared bid packages, and responses to RFIs.
