Outdoor Drainage Project: Wet Backyard and Landscape Renovation

The Drainage Problem: Backyard Creates A Wet Bowl Effect

There were 2 goals to this project. The first goal was to fix drainage issues. The customer’s backyard is relatively small and has a hill down from the house and a hill down from the backyard fence. This creates a bowl that keeps water stuck in the middle for extended periods of time. Essentially, the homeowner wanted to use their backyard again. The second goal was to create an elegant and natural transition from the garage down to the backyard itself.

Step # 1:  Outdoor Drainage Consultation

The customer reached out to us at KG Landscape and scheduled an outdoor drainage consolation with Kent, our owner and lead designer. Kent met with the customer at her home to observe the backyard hillside drainage issue in person. While there, he collected the site information needed to provide a detailed plan/estimate for a long term solution to the drainage problem.   


Step # 2: A Detailed Proposal

After careful consideration of the drainage problem and the options available to correct the issue, we put together a detailed plan to solve the customer’s backyard drainage problems in a cost effective and dependable way. There were also a number of landscape design options that we discussed before landing on a final design plan for a hillside planting and stone steps down from the back garage door.

Drainage Solution Objective: We determined that there is no lower point for the water in the backyard to go. When that is the situation, we install a dry well with an exterior sump pump is the answer. The sump pump in the dry well will pump the water out from the collection area in the backyard and push the water into the creek area and off the property. The water from the house sump pump will be collected into a french drain in back. Next, 3 catch basins will collect water from the roof and into the french drain as well. Finally, the french drain will collect and transport all the water into the dry well. The water from the driveway will also be collected and stored in the dry well.

Step # 4: Project Completion

All of the work described in the proposal was completed and thoroughly tested by running water through all components of the system. Both we and the customer were 100% confident the drainage issues have been solved in a high quality and reliably way.  We’ve kept in touch with the customer and they’ve had no more puddling, much firmer grass in the backyard, and no more erosion issues since this work was completed in early 2018.
