Commercial Downspout & Roof Leader Extensions for Old Lyme, CT Properties

Downspout and roof leader discharge at grade against commercial building foundations is one of the most consistently underaddressed sources of commercial foundation moisture on the Connecticut Shoreline, and Old Lyme's commercial properties are no exception. The volume of roof water a commercial building generates during a Connecticut Shoreline rain event is substantial, and when that volume discharges at the base of the foundation perimeter on Old Lyme commercial lots where flat terrain provides no natural drainage path away from the building, the accumulated effect on foundation perimeter soil saturation is significant.

On the Halls Road commercial corridor, the retail and service commercial buildings that line Old Lyme's principal commercial street have roof leaders that in many cases discharge at or near the foundation on sites where the flat terrain between I-95 and the south gives that discharged water nowhere to drain naturally. The Old Lyme Marketplace, Walgreens, Big Y, and the other Halls Road commercial properties generate large roof water volumes that need to be routed underground and away from the building perimeter to protect commercial foundations and eliminate the saturated perimeter conditions that contribute to foundation moisture problems.

In the Boston Post Road corridor adjacent to the Lyme Street Historic District, the older commercial buildings that sit in this historic context may have had leaders discharging at grade against their foundations for years. Routing those leaders underground is the most direct and cost-effective improvement available for reducing foundation moisture on these Boston Post Road commercial properties, and it is the correction we recommend first on these sites before discussing any more extensive foundation drainage work.

On Route 156 and in the Sound View Village District coastal commercial zone, the flat coastal terrain means that roof leader discharge at grade has no natural path away from the commercial building perimeter. The seasonal water table elevation in this zone, under tidal influence from Long Island Sound and the Connecticut River estuary, means the foundation perimeter soil is already near saturation during wet periods before roof leader discharge adds to that condition. Underground extensions that route commercial roof water to a discharge point at a compliant distance from the building and the applicable regulated resources are the practical correction for this zone.

On the light industrial and distribution properties near Exit 70 and 71 on Hatchetts Hill Road and Vista Drive, commercial building roof leaders serve larger roof areas and generate higher water volumes than the retail and service commercial properties in Old Lyme's other commercial zones. Underground extensions on these industrial properties route significant volumes of roof water away from the building perimeter and to discharge points appropriate for the terrain and the applicable stormwater regulations near the town's regulated inland resources.
