Como Lake is an important and central recreation spot in St. Paul. Its water quality is a harbinger of water resource issues in its watershed.
In the lake, poor water quality has
caused problems with water clarity and has periodically created an unpleasant odor in the area around the lake. Elsewhere in the subwatershed, excessive runoff has caused problems with intercommunity flooding and other water quality concerns.
CRWD, along with the cities of St. Paul, Falcon Heights and Roseville, and Ramsey County, have worked cooperatively to evaluate, design, construct, and fund several stormwater BMPs in an area west of Como Lake to address these problems. The Arlington Pascal Stormwater Improvement Project has resulted in the construction of several BMPs including eight raingardens, eight underground infiltration trenches, a large underground stormwater/storage and infiltration facility, a stormwater pond, and storm drain improvements.
In 2007, the project was substantially completed, and CRWD was presented with two awards: the Sustainable St. Paul award, for innovation and use of partnership to improve water quality; and a Golden Blooms Award from St. Paul Parks and Recreation, for the 2,500-square-foot raingarden at Frankson and McKinley Streets. The Arlington Pascal Stormwater Improvement Project also received 2008 Project of the Year awarded by the Minnesota Association of Watershed Districts.

CRWD regularly inspects and maintains the BMPs and also monitors their performance at volume and pollutant load reductions. For more information on these BMPs and to access a detailed analysis of the BMPs, click here.
