The West Irving Creek drainage project and what it means for nearby yards

The City of Irving is carrying out channel improvements along West Irving Creek, between Pioneer Drive and Oakdale Road, in three separate projects. The first is under construction, and the work is paid for partly by an increase in the city’s Municipal Drainage Utility rate and partly by a grant from the Texas Water Development Board. Rein Irving Drainage Company does not work on the project; this post explains what it is, using the city’s published project information, and how it relates to drainage on private lots nearby.

What the project is

West Irving Creek runs through south and west Irving toward the Trinity. Channel improvements of this kind generally reshape and line a creek channel so it carries more water during storms, with less erosion of its banks. The city has split the reach between Pioneer Drive and Oakdale Road into three projects, built in sequence rather than all at once.

For current schedules, closures and maps, the City of Irving’s own project pages are the source to check. Work in and along a channel can mean temporary detours, equipment staging and noise for the streets beside it, and the city posts those details as each project moves forward.

Why it matters to residents

Much of the ground near Irving’s creeks maps in the USDA soil survey as frequently flooded clay. At a sample point in south Irving, near Shady Grove, the soil is Frio silty clay, frequently flooded; in north Irving the creek bottoms map as Ovan clay, also frequently flooded. Ground like that drains slowly and sits low, which is why channel capacity matters for the streets and lots close to the creek.

The project also explains a line on Irving utility bills. The Municipal Drainage Utility fee pays for the city’s storm drainage system, and the city has tied part of the West Irving Creek funding to an increase in that rate.

What it does not change on a private lot

A bigger, more stable creek channel helps when the creek itself is the source of the water. It does not change how rain moves on an individual lot. Three situations are worth separating:

1. Water rising from the creek. This is a floodplain matter. Channel work like this is the right kind of response, and a yard drain cannot stop it. The guide to floodplain or drainage problems explains how to tell.
2. Rain on the lot with nowhere to go. Puddles in a back yard, water at the slab and soggy side yards come from the lot’s own roof, grade and soil. They need catch basins, buried downspouts, regrading or a French drain, whatever happens in the channel.
3. A lot whose outlet sits low. Near the creek, the only lower ground may be close to the channel, and outlets can sit higher than the yard when water is up. That is where an exterior sump sometimes earns its place.

Insurance and the floodplain

A standard homeowners policy generally excludes flood. If your property is near West Irving Creek, checking its flood zone on the FEMA flood map is worth doing whether or not you are planning drainage work. The guide to whether insurance covers yard flooding covers the basics.

Irving’s other drainage work

West Irving Creek is one of several drainage projects the city has carried out. It built a subdrain on Wingren Drive in Las Colinas to deal with groundwater, rebuilt a driveway approach on Rochelle Road to keep stormwater in the public right-of-way, and built about 900 feet of concrete flume behind Denali Drive. Together they show the same pattern a homeowner faces at a smaller scale: find where the water comes from, then give it a path that works.

If your yard holds water

If your lot near the creek holds rain after storms, start by watching where the water comes from. If it is the lot’s own rain, the guide to fixing yard drainage walks through the options, and the estimate request page takes a photo and an address.
