[CLARIFICATION] P&Z: No Full Basements In Flood Zones; Piers, Pilings Remain Only Options

Westport Planning & Zoning Commission chair Danielle Dobin says that — despite the implication in today’s “06880” story that the P&Z is considering a change in flood zone regulations — the pre-application hearing resulted in a resounding “no.”

Piers and pilings will continue to be the only options for homeowners living near the water.

On Thursday, 2 local design professionals presented a potential amendment to the current flood regulations. The changes would have permitted filling properties to FEMA-mandated elevations, in lieu of raising residential dwellings on piers or pilings.

P&Z staff and commissioners expressed concerns about the effect of foundations and basements on subsurface draining, and neighboring properties on lower grades.

They also addressed the impact of future sea level rise, and the departure from best practices that support raising flood-prone structures over raising the grade of flood-prone lots.

Staff and commissions noted that fill in flood zones is specifically discouraged by FEMA regulations.

Current zoning regulations regarding fill and basements in flood zones will not change, Dobin emphasized.

Flood Zone Change: Full Basements Instead Of Piers And Pilings?

It’s not easy living in a flood zone. Superstorm Sandy made the risks real. Since then, dozens of Westporters living near the water have raised their homes, using piers or pilings.

That may no longer be the only option.

Gloria Gouveia reports: At last Thursday’s Planning & Zoning Commission meeting, 2 local design professionals presented a potential amendment to Westport’s flood zone requirements.

The pre-application process gives applicants the opportunity to explore ideas with the P&Z in a brief, informal, non-binding discussion, saving the time and expense of a formal application.

Citing a desire to provide full basements for homes in some Special Flood Hazard Zones, the proposal would permit filling properties to FEMA-mandated elevations in lieu of raising residential dwellings on piers or pilings.

The applicants testified that the benefits associated with raising the height of the land and the use of flood-proofing, versus elevating the structure, included: more (basement) floor area: egress at grade: enhanced flood protection and improved esthetics.

Typically, residential construction in SFHZs requires elevating and supporting structures with piers or pilings that are less of an impediment to flood waters than traditional foundations.

P&Z staff and several commissioners expressed concerns about the effect of foundations and basements on subservice drainage, and neighboring properties at lower grades.

Other issues addressed by staff members included the impact of future sea level rise, and the departure from best practices which support raising flood prone structures over raising the grade of flood prone lots.

Current zoning regulations prohibit the use and/or placement of fill for any purpose in Special Hazard Flood Zones.
