City says geotech, flood study raise Brickyard Creek bridge cost to about $1.3 million; staff to pursue grant-funded city-led project
Summary
Staff reported that geotechnical work showing liquefaction-prone soils and an updated 100-year flood hydraulic study raised a bridge estimate from about $400,000 to roughly $1.3 million; council endorsed removing the structure from the development agreement and pursuing grant funding for a city-managed project.
City staff told the council that design work for the North Trail (Brickyard Creek) crossing uncovered two items that materially increased cost estimates: subsurface soils susceptible to liquefaction and a hydraulic study requiring a longer, higher structure for 100-year flood compliance. "Between the two of those, the cost increased to about 1,300,000," staff said.
Because the increased cost is well above the original budget, staff proposed removing the structure from the existing developer agreement so the city can pursue grants and manage the project directly. Staff said ground improvement to address liquefaction added about $400,000 and that grant-funded projects typically require a local match of roughly 13.5''15%. Council members pressed on emergency egress, local traffic impacts and homeowner communications; staff said they are coordinating keyed emergency access with the fire department and are in early talks with the school district about using a bus-barn access for emergencies. The city will return with an amended development-agreement amendment and a funding plan if grant applications are successful.
