5.8 Capital Improvement Program

Much of the phosphorus load reduction required to meet Lake Minnewashta in-lake nutrient concentration goals is expected to be accomplished through regulation – including more stringent regulation on phosphorus loading than is now allowed under the existing rules – and load reduction allocations to the cities.  Regulation and the local projects identified in the Lake Virginia TMDL, along with a reduction in load contributed from Lake Minnewashta, would accomplish the load reduction to meet Lake Virginia goals.  A vegetation management plan would evaluate the possibility of achieving internal load reduction through aquatic plant management or biomanipulation.

The capital improvement program identified below includes projects that will progress the District toward achieving its various goals for the subwatershed.  This program is not a comprehensive list of all capital needs or potential projects within the subwatershed, and is limited by available financial resources and staff capacity to manage projects.  These priority projects are intended to:

  • Achieve nutrient load reductions in Lake Virginia as set forth in the draft nutrient TMDL study now underway.
  • Mitigate the impacts of future development on downstream resources.
