The Competition

Competition Objectives

Design Goals

Provide a hands-on learning experience through which design, construction and development professionals in the Great Plains region will gain meaningful experience in working with LID principles and practices that can be applied to their everyday practices.

Demonstrate to local design professionals, real estate developers, civic groups, and the general public the economic, environmental and social benefits that are available to entities that adopt and innovate with LID.

Identify and attempt to remove potential barriers to the implementation of LID practices in the area, while illustrating practicality by showing what is feasible.

Encourage through the body of work represented by the entries submitted, greater use of these LID practices in our area and highlight local incentives where applicable.

Recognize the participants and finalist design teams for their creativity, innovation and application of LID principles and practices.

Prepare contestants for potential upcoming regulations requiring LID techniques by giving them an open forum to explore ideas and design methods that strive to accelerate the implementation of innovative LID principles and practices.

  • Preserve and protect natural features that provide natural functions that help with managing and filtering stormwater.
  • Use decentralized, small-scale LID practices to create a system to:
  • Reduce runoff water quantity by mimicking the pre-development hydrology of the site.
  • Improve the water quality of runoff leaving the site.
  • Minimize and disconnect impervious surfaces from the storm sewer and lengthen the time of concentration.
  • Demonstrate cost benefits designing with LID principles and practices.
  • Realize the environmental, social, and economic benefits inherent with the life-cycle costs of LID practices and utilize them to increase marketability of the development and long-term property values.
  • Identify current codes that prohibit or inhibit the construction or implementation of LID techniques.

What is Low Impact Development (LID)?

LID is a toolbox of site-scale practices that the site designer and developer can utilize to:

  • manage urban rainfall where it occurs for minimized stormwater concentration and runoff
  • potentially lower short-term and long-term development costs
  • improve water quality
  • enhance natural habitat and flood control
  • improve green space aesthetics and potentially increase property values
  • increase community quality of life and livability

There are many practices that are used to support these benefits, including bioretention systems, rain gardens, vegetated rooftops, bioswales, rain barrels, and permeable pavements to name a few. By implementing LID principles and practices, water can be managed in a way that reduces the impact of built areas on the environment while providing numerous additional benefits.

Project Summary

The design project represents an actual property in the Omaha region selected to showcase LID principles and practices.

Design Project

Urban Watershed/Combined Sewer Overflow

This project is located in a fully built-out area of north-central Omaha. The location covers a 101 acre watershed within the Omaha combined sewer service area and has one combined sewer outfall associated with it. The land use in this area is primarily single-family residential homes but also includes commercial and high-density developments. The design goal for this project is to utilize LID principles and practices within the watershed to reduce or eliminate the occurrence of combined sewer overflows (CSO).
