<br /> Bonestroo's St. Paul campus sits on a critical regional stormwater
<br /> BONESTROO�S UPDATED S�.PAUL management basin managing runoff from Highway 36. A challenge in
<br /> CAMPUSINCORPORATESANUMBER designing and constructing a third campus building was providing sufficient
<br /> OFSUSTAINABLESTORMWATER stormwater management with the existing pond. The pond was split in
<br /> two, and its surface area and volume were expanded, providing additional
<br /> MANAGEMENT FEATURES AND IS
<br /> storage capacity and helping meet nutrient removal goals.
<br /> AESTHEflCALLY PLEASING TO
<br /> EMPLOYEESANDVISITORS A subsurface stormwater storage system was installed beneath the
<br /> reconstructed porous paver parking lots. Surface water flows through the
<br /> pavers into seven storage/infiltration chambers. The chambers slow the
<br /> rate of runoff entering the pond, and improve water quality by filtering the
<br /> water. Manholes are used to monitor the level of treatment occurring. The
<br /> south parking lot features a rainwater garden that is hydraulically
<br /> connected to the larger porous paver system.
<br /> The pond slopes feature native vegetation. A long-term benefit will be the
<br /> enhanced wildlife habitat resulting from shoreline's emergent plantings. A
<br /> rip-rap streambed was installed on the property's southern edge with a
<br /> settling pool that captures floating debris from the highway.
