H-GAC Releases Low Impact Development Guide

The Houston-Galveston region is forecasted to grow by more than 3.5 million people by 2040. This growth will be followed by more development, leading to more paved surfaces and infrastructure that will alter natural drainage patterns and impact stormwater quality.

Low Impact Development (LID) is an alternative method to land development that captures and disperses stormwater as close to its source as possible. LID techniques are proven to decrease development and infrastructure expenditures, reduce operations and maintenance costs, and enhance stormwater quality.

The Houston-Galveston Area Council is pleased to announce the release of Designing for Impact: A Regional Guide to Low Impact Development. This guide explains LID functions, benefits, best management practices, and ways to overcome obstacles to implementation.

The guide also looks at case studies showcasing successful LID projects from around the region and considers five hypothetical site plans comparing costs and environmental impacts of LID and conventional design.

This guide is part of H-GAC’s Designing for Impact project, in cooperation with the Environmental Protection Agency (EPA) Gulf of Mexico Program, to promote and educate the public, designers, developers and environmental stakeholders about LID benefits. H-GAC also maintains an interactive mapping tool highlighting LID practices across the 13-county H-GAC region. Users can simply click on a site on the map to learn more about the features and benefits of the practices and see photos from the specific project. People using the map can also submit information about other LID projects not currently mapped. 

A digital copy of the Designing for Impact guide can be found on the H-GAC website ( To request a printed copy, contact Mary Martha Gaiennie at
