Townsend Park Watershed Improvement Plan

Townsend Park Watershed Improvement PlanSep 20, 2022

The Townsend Park Watershed Improvement Plan will consist of three phases. This is an outline of the future project which is  anticipated to begin Spring of 2023.

Project Updates


This project is currently in the design phase.

Project Overview:

This project aims to improve the speed with which water is conveyed to Townsend Pond from the neighborhoods upstream. This will help reduce flooding and water flowing outside of easements.


Phase 1: located within the greenbelt located upstream from Townsend Park Pond, between 19th St SW and Stonegate Ct SW.

Phase 2: located in and around the Townsend Park Pond Forebay.

Phase 3: located in and around Townsend Park Pond



Townsend Park Pond was donated to the City of Altoona by Robert and Sharon Townsend. The City of Altoona later purchased the former Townsend Family home in 2018. The home was renovated into the Townsend Community Center, managed by the Altoona Campus, with the lower level serving as the Polk County Senior Meal Site.  The pond and surrounding green space will become a City park. Before it can become a park, however, some improvements need to be made to the pond, its forebay, its dam, and the upstream storm sewer system. These improvements will be split into three phases, the first of which will begin spring of 2023.

  • Phase one improvements will include upsizing of upstream storm sewer pipes located in the green space south of 19th St SW and Stonegate Ct SW as well as adding a large culvert under 6th Ave SW. This phase will also include improvements to the pond located behind the eastern Stonegate Ct SW cul-de-sac and it will convert the existing dam overflow from a pipe to an earthen spillway. The focus of this phase of the project is to prevent water from pooling on private property outside of existing stormwater flowage easements during storm events and to prevent flooding of homes should a 100-year storm event occur.


  • Phase two will include the dredging and armoring of the Townsend Pond forebay, which functions as a silt trap to prevent silt from entering the main pond.


  • Phase three will include the expansion and dredging of Townsend Pond and repairs to the dam.
  • After the third phase is complete, planning of how the park space can be utilized will begin.



Phase 1 will begin construction in Spring 2023.

Phases 2 and 3 will follow in subsequent years.


Road Closures

Phase 1 will close a small segment of 6th Ave SW.

Phases 2 and 3 will not involve any road closures.

Detour Routes

The detour routes are TBD.

Sidewalk & Trail Closures

All sidewalks and trails within the project area will be closed until construction is complete.
