PACE Anclote West Watershed

Model Development and Floodplain Delineation

The PACE study area is comprised of three watersheds: Pithlachascotee River, Anclote East of Suncoast, and Anclote West.  DES was issued a task work authorization (TWA) to develop a watershed model, perform design storm simulations, and map floodplains for the Anclote West watershed.

 

The Anclote West watershed is a particularly important part of the overall PACE study area, as it: includes areas that are, historically, the most flood-prone of the three watersheds; is the site of flow exchange between the Pithlachascotee and Anclote River during extreme floods; encompasses a rapidly growing area of Pasco County, including the SR 54 corridor (South Market Area, aka, Gateway Crossings) with its many planned developments: Mitchell Ranch, Western Hub, Trinity East, Starkey, Asturia, and Suncoast Crossings; and includes District-owned lands with potential storage for conservation and flood mitigation BMPs.

SWFWMD TWA No. 15TW-94 was issued to DES to perform Watershed Management Plan - Floodplain Analysis tasks in the Anclote West Watershed.

 

These tasks include:

 

  • Watershed Model Parameterization,
  • Watershed Model Development,
  • Floodplain Delineation, and
  • Preliminary Floodplain Open House

 

elements of the WMP.

 

This work builds upon Anclote West Watershed Evaluation tasks previously completed by DES under TWA No. 14TW-42.
