OO RIDGE IG 0 RECD STCTI C 09-01 The Shoreview City Council has ordered the Woodbridge Neighborhood Street Project to proceed, which includes the reconstruction of public low volume residential streets in the neighborhood east of Lake Owasso. The project is now in the public bidding phase; we anticipate having a construction contract considered by the City Council in May. The project includes about 9,200 square yards of pervious concrete paving (3/4 mile of streets) and will be dependant on infiltration as no conventional storm drainage treatment/conveyance system is planned. A goal of the project was to eliminate an existing direct, untreated storm water discharge into Lake Owasso, building off of the previous trial use of the material in a neighborhood alleyway on the west side of the Lake (2007). Shoreview's City Council enthusiastically supported the use of pervious concrete in conjunction with the sandy soils to address storm water quality concerns. This appears to be the largest commitment to pervious pavement in any single public roadway project in Minnesota, if not the Midwest. Regardless, this is a very important step for advancing the use of alternative pavement technologies to address local government infrastructure needs, and there has been an extraordinary amount of interest in Shoreview's project. Local media, as well as the Industry and Research communities are expected to be involved at some point. Groundwater monitoring facilities are being designed and installed as part of the project, and the Concrete Ready-mix companies are anticipating training and education/outreach activities in conjunction with the construction. The project was submitted for American Recovery and Reinvestment Act (ARRA) Funding; i.e. in the Clean Water categories for "Green Infrastructure". The City has studied and acknowledged the maintenance commitments that will be necessary to ensure future performance of the pervious surface. The City was already planning the purchase of a regenerative air sweeper. In addition to education/outreach needed for the maintenance personnel, the City will develop an "owner's manual" for the neighborhood as far as things that they may have been used to doing (like sweeping their boulevard into the street, storing loose excavated materials on the pavement, etc) that will have to change in the future. Shoreview has also recently upgraded policies, practices and ordinances in general to reflect modern thinking for grading and erosion control permitting and inspections, so this neighborhood will likely be an area to focus those efforts.
