Overview

This City park project was a re-channelization of a drainage swale designed by Thompson Dreessen & Dorner, Inc, of Omaha, NE. The channel was needed to mitigate an existing roadside ditch that the Corps of Engineers claimed as a jurisdictional waterway.

Issues

  • Quick Vegetation Required.

  • Natural tan color for TRM required.

  • Significant rain events.

Problem

This City park project was a re-channelization of a drainage swale designed by Thompson Dreessen & Dorner, Inc, of Omaha, NE. The channel was needed to mitigate and existing road side ditch that the Corps of Engineers claimed as a
jurisdictional waterway.

Solution

PS 42 TRM and SC32 degradable erosion blanket were installed in June. Before much vegetation was established this project quickly received 3 intense rain events over 2 inches of rain each. Fully vegetating is a mere 4 weeks, this project took some of the most intense rain events in an abnormally wet year.

Results

Fully vegetating is a mere 4 weeks, this project took some of the most intense rain events in an abnormally wet year.
