4.15 Erosion Control

Goal 15 - Erosion Control

Control temporary sources of sediment resulting from land disturbance and identify, minimize and correct the effects of sedimentation from erosion-prone and sediment source areas.


Erosion within the subwatershed can result in sediment being transported to lakes, wetlands, and streams, where it can degrade water quality and habitat. Sediment accumulating in channels, culverts, and other facilities can reduce their ability to convey stormwater, while erosion can undermine their stability.

Restoration of lakeshore with native vegetation would help increase or maintain infiltration rates; decrease or maintain runoff rates and pollutant conveyance to water resources; help create fish and wildlife habitat; and help minimize erosion. Identifying, addressing, and preventing erosion is necessary to meet District goals as well as to meet state and federal nondegradation, water quality and biological integrity requirements and to prevent the need for future TMDLs.

Requiring new development and redevelopment to infiltrate some of the new stormwater generated would reduce post-development volumes downstream and help reduce future erosion in streams and channels; minimize new pollutant loading that would have been conveyed by that stormwater; and help maintain groundwater levels, preserving wetlands.

Strategies in the Schutz Lake subwatershed will focus on identifying erosion problems and working with LGUs to correct them, as well as considering potential downstream impacts of new volumes discharged from development.

Desired Outcomes: Reduction in pollutant loading of temporary and permanent nature from erosion to supplement other goals.


  • In-lake nutrient concentrations/Trophic State Index Scores (TSI) for Schutz Lake Nutrient loading goals (lbs) for Schutz Lake
  • Linear feet of shoreline protected in Key Conservation Areas
  • Linear feet and width of riparian areas protected in Key Conservation Areas

Goal 15.1 - Schutz Lake

Identify and address erosion problems in the subwatershed.


  1. Identify, inventory, and prioritize erosion problems in the subwatershed.
  2. Work cooperatively with LGUs to address identified erosion problems.
  3. Regulate new development and redevelopment and ensure compliance with erosion control standards.

Goal 15.2 - Schutz Lake

Manage water volumes to the channel draining the upper subwatershed to prevent further erosion.


  1. Implement the regulatory and management activities identified in this plan.
  2. Inspect this channel periodically to assess its condition.
  3. Work cooperatively with the City of Victoria to reduce stormwater volumes to prevent erosion and sediment transport and stabilize to streambanks as necessary.
