Conceptual Design: Torti Gallas

Buildings implemented by Minno & Wasko


How do we make neighborhood with the rules that makes this?


BFE’s relative to the Shoreline


Variety of Raised BFE (Base Flood Elevation) Solutions – Raising grade out of the Floodplain

Belmont Bay, VA

Kemer, Turkey


Variety of BFE Solutions – Raising perceived ground out of the floodplain

Variety of BFE Solutions – Building Town Center out of the floodplain on top of parking

Atlantic Station, Atlanta, GA

Bay Street, Tampa, FL


Relying on solutions external to the neighborhood – ninth ward (levees, new flood gates and walls)

Or we can choose to build/rebuild in the areas at risk…


….and try to make a neighborhood (adjusted to the requirements of raised BFE’s and addt’l freeboard)


This project replaced Barracks


Best practice of Burms/Dunes placed along the waters edge to buffer the wave action


Here we try to address minimizing damage in flood/storm surge events, where citizens in risk prone areas go

elsewhere during the events -- We are NOT creating full survivalist solutions

for people who foolishly choose to ride out the storm.


Variety of BFE [Base Flood Elevation] Building Type Strategies

BFE

Everything below BFE line is sacrificial; no habitable residential space allowed.


Raised Plynth - $$$$ (only top commanders)


Establishing Frontage - Grounding Details – Smart Vents


Design with Breakaway Walls, providing more secure garages – (More to insure $$)

Where alleys do not exist, parking solutions can be side-loaded off of a shared stub driveway, to keep the frontages clean of exposed vehicular and other

storage.


Neighborhood Frontage with Open Foundation (Stilts)

Key terms:

BFE (Base Flood Elevation) : Elevation below which no habitable spaces should be built

Freeboard: Space between bottom of lowest horizontal Structural Member and BFE


Neighborhood Frontage with Stilts – Scour resistant foundation, reinforced piers, bond beam at floor


Miami-Dade Design Standards – Base Plate Details, Embedded tie down rods


Vertical Construction - Details

Naked Completed


Grounding Details – Louvers/Breakaway Lattice


Miami-Dade Design Standards – Strapping, Tie-Down Rods


Best Practice: Hipped roofs provide better wind resistance.


Two required means of egress; one secure, one at sacraficial

Front w/ concrete porch and stair Rear w/ wood porch and stair


Raised floor 5’ over 4’ BFE to allow for greater freeboard and the ability to park cars and reduce lot size . It was decided to leave condensers just above BFE level to minimize noise to residents and impact to views

Plan was able to be much more compact than conventional alley loaded schemes.


Overall land dedicated to parking can be reduced; land area dedicated to active uses can remain the same.

Because tuck under lots take less space than conventional lots (parking efficiency); land on higher ground could be upzoned to provide more housing; lower lands at risk can be “renaturalized” or parked w/o impacting community tax base or without loss of population.

Opportunity:


Conventional lot size vs. tuck under lotConventional Tuck-Under

Opportunity:

(Illegal!)

Required BFE + Freeboard may allow for more compact lot sizes, where units are parked below, and adjacent garages and parking spaces removed. Affected jurisdictions may want to consider allowing more density and lot subdivision at higher elevations to keep your communities from depopulating due to places not being rebuilt at lower elevations.

Land formerly used for parking can be freed up for development. Redevelopment is an opportunity to improve overall community quality by requiring screening of on-site parking

To improve street frontages, shoreline communities may want to allow for ground floor, at-risk, foyers and mudrooms (all with breakaway construction), to screen parking and provide safety - “eyes on the street”


Supermarkets can be on upper floors with service retail along street lining parking load
