Drainage

The rains over this past fall, along with the heavy snowstorm that we experienced a few weeks back, can really bring to light drainage problems. Areas on your property that did not seem to have an issue may suddenly exhibit drainage problems, or lack there of. Typically, drainage problems tend to become exacerbated once the ground is saturated. We have been receiving quite a few calls recently in regards to drainage, so we thought it would be a great topic to address.



Typical Problems & Solutions

Puddles on pedestrian surfaces  Over time, either due to settling or root intrusion, the original grade of walkways may change resulting in standing water. Typically a minor inconvenience in warm weather can quickly become a major hazard in cold weather. When this occurs, a section of the walkway may need to be repaired or replaced, or the grade along the edge can be adjusted to allow for water to drain off of the walk or driveway.



Pooling of water along bed edges or in planting beds   If this is occurring in a bed in the middle of your yard, probably not a major issue, but if occurring in a foundation bed, it should definitely be addressed to avoid excess water from settling near the foundation. Typically these issues can be resolved by connecting the downspouts to drain pipe and extending past the edge of the bed or by raising the grade at the foundation to create positive flow away from the foundation. Also, creating a swale and lining with filter cloth and decorative river cobble can help to move the water out to an area where it can properly sheet drain. By incorporating a few larger boulders, along with the river cobble, an aesthetic "stream bed" appearance can be created.

The dreaded soggy spot in the yard where the grass always looks horrible   This usually indicates a low spot where water settles, which can be corrected by raising the grade and repairing with sod. Maybe you live near the Bay and your yard is extremely flat and always pretty much soggy. Probably one of the more difficult issues, but we have had success by installing underground French drains which can be ran to either a culvert area or out to the water. Typically, site grading also should occur along with installation of drainage. May be a larger project, but often allows for utilization of lawn areas for play or entertaining, that were previously under-utilized.

Of course these are just a few examples and each property is different. If you are experiencing any drainage problems and would like us to meet with you to discuss some solutions, please feel free to call me at 410-956-1344 or email me at jharrison@exteriorimage.com. I look forward to hearing from you!
