PROJECT DESCRIPTION
The City of Memphis embarked on a stormwater program to alleviate flood-related issues and outlined a program structure similar to the 10-year Sewer Assessment and Rehabilitation Program (commonly referred to as SARP10). In 2019 the City issued an RFQ for stormwater program manager (SWPM) services. After submittals, evaluations, and interviews, Allworld Project Management was selected and awarded a contract to lead the program. As an example, a summary of our work on the Cane Creek modeling effort is provided below:

CANE CREEK WATERSHED
The Cane Creek Watershed has a total drainage area of 5,110 acres. For the hydrologic component of the modeling, Cane Creek Watershed was divided into 297 sub-basins using the Digital Elevation Model (DEM) from 2012 Shelby County LiDAR data. Initially, the sub-basins were delineated with a minimum size of 100 acres. InfoSWMM was integrated with ArcGIS and used to simulate and predict existing and proposed conditions for effective management of urban storm water systems for both existing and proposed conditions. The results of the model were used to identify locations of existing condition flooding and to identify appropriate capital improvement projects (CIPs) to address existing flooding problems.

OUR ROLE
2015-2021
AWPM participated extensively in the effort to study and plan improvements to the City’s stormwater infrastructure. Of the 21 studies awarded, Allworld has participated in 7 studies. These stormwater modeling projects include significant data collection and verification, GIS development, and stormwater modeling in a SWMM modeling environment (via InfoSWMM).
