Flood prone communities are beginning to establishelevation design guidelines, as a user’s manual onhow to raise buildings above base flood elevation, or theelevation to which floodwater is anticipated to rise duringa 100-year storm event.

The Breezy Point Home Elevation Studyemployed a novel approach on design guidelines for aunique coastal community, by focusing on urbanism asmuch as on architecture.

Architectural Standards were modeled on the potentialurban context of elevated homes, visualizing a set ofStudy Options to inform homeowners on how theirchoice of architectural standards will affect theirneighborhood character, resulting in the NeighborhoodDesign Guidelines.

The study options are meant to serve as a guidefor homeowners to visualize the impact of certainarchitectural standards on the varied neighborhoodcontext. The options presented herein are by nomeans absolute, and are open to interpretationand improvement by homeowners and theirarchitects when choosing to elevate their homes.The intent is to bring awareness of the quality oflife at the neighborhood scale when choosingarchitectural standards for a single home.

Home owners need to answer two 2 questions:

How high to elevate? How to choose architectural standards?



Planning Analysis and Neighborhood Guidelines methodology can be applied to other flood prone areas:

Planning Analysis

1. Calculate the RRE

2. Explore the impact on the streetscape

3. Identify neighborhood typologies

Neighborhood Guidelines

1. Establish the neighborhood areas

2. Gather community feedback

3. Apply architectural areas to the areas
