3.2 Water Quantity
- Several landlocked subwatershed units
and individual subbasins are present in the subwatershed. As identified in the HHPLS, the cities
of Chanhassen and Shorewood have contemplated in their Local Water
Management Plans connecting and/or draining these basins, altering local
hydrology and potentially creating downstream volume impacts. Within these landlocked basins, any
future development or redevelopment should minimize creation of new
stormwater volumes. Outletting will
generally be discouraged unless there is a demonstrated threat to property
structures or public safety.
- Development, redevelopment, and
reconstruction in the subwatershed is predicted to increase volume of
stormwater runoff from the watershed as well as increased nutrient and TSS
- Stormwater velocity has caused erosion
in the channel that conveys drainage from the southern subwatershed unit
to the lake.
