Portland - VersiGrid™ Pervious Grass Drive and Parking
|
|
This historic building was saved from being bulldozed for highway expansion. They owned a small lot in the "old town" neighborhood of Portland, and moved the historic building to their lot.
When they went to apply for a curb cut, for building permits, etc they were told that the footprint of the house was too large for that size of lot.
The City of Portland has restrictions concerning the total percentage of a lot or acreage which may be covered with impervious structures - which includes the buildings and any impervious roadway such as concrete, asphalt, on non-engineered stone (many US cities are implementing similar zoning laws).
The footprint of the home consumed their allowance for impervious structures - they would not even be allowed a curb cut for off-street parking.
They contacted VersiGrid™, for an attractive and durable pervious roadway.
They decided upon the grass paving option
Please note: the "grass road" was seeded in early winter.

they used VersiGrid™ for the approach, the side lane to the rear, the grass lawn and turnaround/parking area in the backyard, and the garage approach.
As a result, they were allowed to develop almost the entire acreage with structures: buildings and driveways.
But the effect is just the opposite! The entire eco-paved grass driveway and parking area appears as a normal, residential lawn.
The only difference: the VersiGrid™-reinforced and stabilized grass is able to support any vehicle weight which is legally allowed on any city street in the nation (vehicular LOAD rating of 22+ US Tons / axle, compressive strength of up to 35 tons per sq ft).
