  30. 30. Raised floor 5’ over 4’ BFE to allow for greater freeboard and the ability to park cars and reduce lot size . It wasdecided to leave condensers just above BFE level to minimize noise to residents and impact to viewsPlan was able to be much more compact than conventional alley loaded schemes. Presentation for REBUILDING A RESILIENT NEW JERSEY SHORE
  31. 31. Opportunity: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 couldbe upzoned to provide more housing; lower lands at risk can be “renaturalized” or parked w/o impactingcommunity tax base or without loss of population. Presentation for REBUILDING A RESILIENT NEW JERSEY SHORE
  32. 32. Opportunity: 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 (Illegal!) floor, at-risk, foyers and mudrooms (all with breakaway construction), to screen parking and provide safety - “eyes on the street” Conventional lot size vs. tuck under lot Conventional Tuck-Under Presentation for REBUILDING A RESILIENT NEW JERSEY SHORE
