Mounds View is a quiet residential suburb in the Twin Cities Metro Area, a friendly neighborhood dominated by young families. However, the extremes of cold winters and hot summers wreak havoc on its streets – potholes, cracks and crumbling curbs. As well, the original road design saw stormwater go directly into the drainage system, washing debris and contaminants into nearby Spring Lake.
Mounds View city staff developed a nine year reconstruction plan for 30 miles of roadway that began in 2009. They called on Stantec to give them new ideas and technologies that would respond to residents’ concerns about water pollution. We started with the section of streets with the worst damage and transformed them with a design that was good for vehicles – and the environment. Working closely with City staff and the Rice Creek Watershed District, we incorporated storm water quality and infiltration features like rain gardens and stormceptor structures to prevent sediment, oil and debris from entering Spring Lake. Most of the aggregate torn up from the old road was salvaged and reused.
The work is continuing with up to18.5 miles of road reconstruction slated for 2013. Efficiencies have shaved one year off the original plan (now slated for completion in 2018) and the project is running $3 million below the 2007 estimate. Even better, residents will not be assessed additional tax levies – the city was able to get Municipal State Aid Streets grants that cover most of the costs.
The end result? New roads, a greener city, happy residents and an effective design that will continue to provide benefits well beyond the project lifespan.
