Case Study – Drainage

The following yard drainage case study is real.

The homeowner lived near the bottom of a long, gradual slope where rain water shed and drained naturally to the foot of the hill.

Property owners can spend years throwing money at insufficient solutions to battle nature. Daniel Dean drainage solutions are long lasting.

Poor drainage saturated this property, replacing good vegetation with a boggy swamp.

Drainage Problem in Yard

Little attention was paid to yard drainage during the construction of a custom home in 2015. During heavy rains, water shed from one side of the property and accumulated at the house and drive, which acted as a dam. The property easily became saturated, which promoted a mossy growth, ant piles and muddy pathways from the owner’s dog.

Poor drainage saturated this property, replacing good vegetation with a boggy swamp.

Major NW Houston rain events included:

Both the 2016 flood AND Hurricane Harvey in 2017 flooded the owner’s pool with black mulch, dirt and debris.

Drainage Fix – Reroute Water Flow

The owner finally had enough. He contacted Daniel Dean.

Daniel Dean explained the most cost efficient and longest lasting drainage solution would be to build a berm / swale combination. The berm would prevent shedding water from approaching too near the house and route it to the back yard, where a swale would drain the water away to a lower elevation and into the roadside ditches.

The crew (of two) surveyed the property’s elevation before and after to ensure the correct slope.

Dirt from the swale was used to create the berm, saving money. Roots were pulled up from the swale, the dirt berm compacted, and the area was raked smooth and seeded with winter rye grass.

This drainage job was completed in half a day.

Daniel Dean had the right equipment for all property sizes.

Back yard: dirt from swale was moved to side yard to create berm.

Side yard: a gentle elevation blocked shedding water towards house.

Drainage Results

On December 31, 2020 the owner’s property received nearly 6 inches of rain in 24 hours from a winter storm and flash flood watch. Within hours after the heaviest part of the rain, Daniel Dean’s solution had expelled nearly all water, with only a trickle still flowing away. Two days later, with only occasional sun, most of the property was dry.

Both the 2016 flood AND Hurricane Harvey in 2017 flooded the owner’s pool with black mulch, dirt and debris.

Side yard: the new berm effectively blocks naturally shedding water from collecting against the house.

Back yard: this new swale receives the excessive flow at berm, rerouting water around the pool.
