McKim & Creed to Update Grand Prairie Master Plan

The city of Grand Prairie, Texas, tasked McKim & Creed, Inc. with providing program oversight as well as professional engineering services for an update to its storm water master plan.

The project team—headed by McKim & Creed and including Burton Johnson Engineering, Inc., RLG Consulting Engineers, Halff Associates, and Lockwood, Andrews & Newnam, Inc.—will update Grand Prairie’s storm water master plan, assess problem drainage areas and identify methods for alleviating localized neighborhood flooding. Using 2-D surface flow hydraulic modeling, LiDAR data, GIS and updated survey benchmarks, the team will generate citywide inundation maps that will serve as the foundation for future capital improvement project (CIP) planning. McKim & Creed will provide new 1-foot LiDAR on which to base this project.

Nearly 37% of Grand Prairie's 81-square-mile area lies in a FEMA-designated floodplain and is prone to severe flooding. The city selected McKim & Creed to evaluate current cost-prohibitive solutions and identify more feasible and constructible alternatives.

McKim & Creed will study the movement of surface water in the city and develop recommendations promoting better flow while minimizing the need for large-scale pipe replacement.

“We enjoy the challenge of developing innovative, highly effective solutions to storm water challenges in situations such as this when traditional storm water engineering solutions aren’t feasible or affordable,” said Street Lee, PE, senior vice president with McKim & Creed.

“The City of Grand Prairie is excited to work with McKim & Creed and their team of professional consultants to consolidate and fine-tune our drainage needs,” said Romin A. Khavari, city engineer. “The results will help us prioritize projects and provide an overall updated approach and general strategy for our storm water master plan.”
