Beach Road at the south end of the Lake is about to become the first heavily traveled roadway in New York State (and one of the only roads in all of the Northeast) to be paved with porous asphalt. This technology allows stormwater to drain through and be filtered naturally by the earth below. The silt, salt and pollutants the stormwater carries are expected to be filtered naturally and not go into the Lake.
The $6 million-plus reconstruction project is expected to begin in mid-April, and be completed in about 18 months. The pavement will be installed between Canada Street and Fort George Road. Warren County Director of Public Works, Jeff Tennyson, and the state Department of Transportation, have helped move the project forward, one expected to get national recognition, and set a precedent for other lakeside communities.
Beach Road has been in need of reconstruction for several years. In 2010, Warren County was planning to use traditional asphalt on the road. After attending the North County Stormwater Conference & Trade Show, and seeing several presentations on porous asphalt applications, Randy Rath, project manager at the LGA, and Dave Wick, director of Warren County Soil and Water Conservation District, encouraged the county to consider porous asphalt as an alternative to traditional asphalt.
Together, Randy and Dave quickly conducted research on the possibilities and made a presentation. In 2011, the LGA provided just over $8,000 in funding for a feasibility study with project engineer Tom Baird (Barton & Loguidice), to provide the information the county and state needed to move forward. At the same time, Dave Wick helped draft an application for additional monies to offset any higher cost from using porous asphalt.
Because this technology is still relatively new in the U.S., the county plans to install the infrastructure and storm drain system that would be needed with traditional asphalt, while the road is under construction. This traditional drainage system will be capped off and is expected to be brought online only in the event that the permeable pavement fails and has to be replaced by traditional asphalt at some point in the future.
Stormwater runoff is considered the number one source of pollutants entering Lake George. The dense development at the south end of the Lake, and the many impervious surfaces created by it, increases the volume and rate of flow of stormwater. Along with the stormwater, many contaminants, such as silt, salt and harmful nutrients, are carried directly into the Lake.
According to the Lake George Association (LGA), research studies and previous projects have shown that porous pavement is highly effective in draining stormwater, and as a result, it increases traction, reduces the build up of ice, and requires much less de-icing material in the winter. The amount of salt detected in the south end of the lake has doubled in just over 20 years according to the LGA.
