NY Landscape and Property Management around Lake George/Adirondack Region

Annual Stormwater Managment Maintenance is a Must

A large commercial retailer in Ticonderoga had a bank slide into their stormwater basin and had contacted DeFranco Landscaping for their expertise on how to solve the problem and minimize the chance of it happening again. A 100-foot long steep bank had slid into the large basin. It appears that the slide was most likely due to hydrostatic pressure on the clay soils and shallow bedrock outcroppings which allowed the groundwater to weep right under the clay and eventually making the small amount of soil above the rock to become unstable. When the bank slid, it took the perimeter chain-link fence along with it.

It is critical for any designer to consider long-term maintenance on any of their stormwater measures. This site had an access gate to the main basin, but had very limited access around the perimeter for large trucks and excavating equipment. A temporary access road had to be cut into the bank and due to the stability issues-smaller 1-ton dump trucks were used to haul the material out of the basin location.

Spoil material was removed from the basin and hauled to a flat location on-site, dumped, spread, seeded and mulched in a timely manner per the current NYSDEC stormwater guidelines.

DeFranco Landscaping provided the client with a few different options on how to stabilize the bank. The selected option removed the soil material that had slid into the basin and tapering of the upgradient bank’s slope to help alleviate the soil pressure around the basin’s side slopes. After the material was removed, the area was raked smooth and seeded with a grass seed. Erosion control blankets were installed per the manufacturer’s instructions to help stabilize the banks from sliding again and then the damaged chainlink fence was replaced. Hydroseeding wasn’t used in this option, but was provided as another option.

There are many stormwater regulations that a commercial property owner needs to be aware of. They must comply with various maintenance requirements depending on the type of stormwater management system that they have on their site. Many of these stormwater management systems require annual inspection and maintenance that needs to be properly documented so that they are in compliance with the latest regulations.

Feel free to contact DeFranco Landscaping about your stormwater needs on your site or current project. Anthony DeFranco, PE, CNLP would be happy to provide you with design guidance to keep your project on track, keep you up-to-date on the current stormwater regulations or provide you with services and/or products that have been used on previously successful projects.

With the combination of Anthony DeFranco, PE-Consulting Engineer and DeFranco Landscaping, stormwater projects are handled from the Design and Permitting phase to the Installation/Construction phase.
