Arlington-Pascal Stormwater Improvements:
a subwatershed approach to community-wide flood prevention and water quality improvements
The project was to meet the Como Lake Strategic Management Plan’s objective of improving water quality by reducing phosphorus inputs, while eliminating residential flooding.
EOR completed a detailed study of the sub-watersheds through a series of sophisticated engineering models that included both an extensive hydrologic/hydraulic evaluation and the modeling of existing & proposed conditions using XP-SWMM, while P8 was used to model water quality.
Main Project Components Include:
- 8 community raingardens
- 8 under road, infiltration trenches
- Largest underground storage facility in Minnesota at time of installment
- Regional stormwater pond / infiltration basin
- Municipal stormdrain improvements
Client Benefits:
- Project recognition - multiple awards on the municipal, state, & national level.
- Met phosphorus reduction targets.
- Improved runoff water quality & reduced runoff discharge volume.
- Significant cost savings and elimination of community flooding.
- Cost-sharing plan developed between overlapping cities based on percentage benefit/use.
