ALTERNATIVE A

Alternative A

In this project approach, the City would:

  • Replace the current stream crossing structure (culvert) with a larger culvert in the same location.
  • Relocate the water main to the north and above the new culvert.
  • Construct a sewer pipe that will cross beneath the culvert.
  • Raise the level of Lake Hills Boulevard.
  • Alternative would result in minimal changes to the existing stream channel or surrounding habitat.

Benefits

Anticipated impact

  • Will provide reliability to the water system and work effectively
  • Increased culvert opening will help reduce surface flooding at the site
  • Provides ability for fish passage but does not create additional habitat
  • Impacts to Lake Hills Boulevard during construction
  • Minimal need for easements
  • Impacts to Lake Hills Greenbelt and Federal Field parking lot during construction
  • Least community impact
  • Requires relocation of sewer under creek
