Please consider StabiliGrid™, HomeGrid™ and HoofGrid™  to replace ALL of your vehicular and/or pedestrian traffic surfaces.
StabiliGrid™ may be used to replace almost any asphalt or concrete vehicular traffic surface - including public and private roads, streets, parking lots, bridge roadways, etc.
You may consider StabiliGrid HD™ to be a military/commercial/civil/developmental grade of roadway product
On the other hand, if any of your projects include high-traffic recreational areas - such as football, soccer, polo, rugby, racecourses or other sports/playing fields, please also consider:  >> www.hoofgrid.com/turftrack_grasstrack_horse_race_strathayr.htm

Below are the photos from Koskey's Turf Management residential grass driveway installation. There are also photos of other types of heavy-duty traffic installations (including public roadways).

It addresses some of the FEDERAL standards to which local municipal officials SHOULD BE adhering, according to NEMO, EPA, NRCS, etc.
(Sometimes it takes some local communities a few years - or decades - to catch up with the rest of the nation.)

CLEVELAND, OHIO GRASS ROADWAY :: Stairstepping method, and then trimming in situ with a circular saw
PLEASE NOTE: the project pictured below is for an RV accessway to a parking area at the back of this house.
> Pathway pictured below serves double-duty as both a footpath, and as a driveway for the RV.
> The client decided to install the concrete paving stones pictured below for one of the truck tracks, our HomeGrid for the second track.
Please Note: StabiliGrid™ has a sufficient loadbearing capacity for the RV (or for any vehicle allowed on any public roadway in the USA), when appropriate ESAL values are applied to your design.
> German-certified "Vehicular LOAD" = 20 metric tonnes / axle (app. 22.5 US tons / axle)
> German-certified "Roadway Lifespan" = indefinite
(not expected to decay or decompose, more durable and longlifed than conventional paving, due to insusceptibility to winter ground upheavals resulting form the ground's freeze/thaw cycles)
> German-certified Environmental Compliance: TÜV/Nord and LGA in Germany, Multiple DINS-compliance certifications with DE/EPO/EPA-compliance as well.
(you may find the environmental compatibility ordinances are much more severe and strictly inforced than anywhere in the USA)

PRODUCT INFORMATION AND SUGGESTED APPLICATIONS:
PHOTOS  - GRASS Heavy-Use Vehicular Traffic & Parking Areas ::
 
Below Left: Winter Photo, same area (taken November, 2006):
NOTE: the grass pictured below is the same area, during the grass's winter dormancy phase.
 (i) The edges of the grids are slightly visible, protruding above the soil level.
(ii) These edges support the LOAD from vehicular or pedestrian traffic, preventing damage to tree roots and grass roots from vehicles (because the traffic tires never touch the soil).  
Portland, Oregon Pervious Paving with StabiliGrid, utilizing Infiltration-based Storwmater Management into the design
Note above and left:
The edges of StabiliGrid™ protrude above the level of the infilling of pervious clean gravel.
The weight of the vehicles are supported by the grids - not by the gravel.
This prevents surface compaction of the fill medium - retaining the native infiltration qualities/drainage of the native soil.
Unlike "non-engineered" gravel roads, the natural stone roadways/surfaces using StabiliGrid remain pervious and water-permeable, creating little-or-none incremental Stormwater Runoff.
[I/R = Infiltration Rate, Pass-through Porosity = 82% to 90%]
When correctly engineered, the I/R of the surface may be superior to the I/R of the previous, native soil.

Below:  Vehicular Surfaces Photos of a grass parking area, also used as an occasional and/or temporary grassy lawn when not needed for overflow parking.
Please note below that these parking stalls ARE the bio-remediation.
Stormwater Runoff is diverted ONTO the parking spaces, which functions as infiltration assets.
When correctly engineered and fully utilized, StabiliGrid™ may replace - or render superfluous or unnecessary - any or all additional stormwater runoff or nonpoint source pollution structures, such as:
bio-swales,
infiltration ponds,
greenbreaks and green-buffers,
infiltration trenching,
stormwater runoff diversion or SWR retention/detention structures, and so on ...

such as those new designs required by the EPA under PHASE II Cities, of the NDPES (some "does not require rocket science" types of solutions),
presented for the benefit of SUA-MS4 coordinators (small urban areas "municipal separate storm sewer systems" coordinators)
which are affordable + easily engineered  (without breaking the bank or requiring exorbitant tax increases - which many small cities cannot afford).

NEMO = Nonpoint Education for Municipal Officials
Please feel free to refer to the following URL, which has abundant information about the NEMO project and its application.
Nonpoint Source Pollution Education for Municipal Officials Through various projects and funding sources, BRPC is providing education to municipal officials regarding polluted runoff or "nonpoint" source pollution. The program identifies the different types of pollutants associated with different land uses. The goal of the education program is to help municipal officials recognize the environmental impacts of land use planning decisions. NEMO presentations are available to all communities upon request.
 
MASS / GOV also has plenty of information about NEMO, and the necessity that Municipal Employees discontinue specifying construction standards or materials which create NONPOINT water pollution. (SOURCE = http://www.mass.gov/dep/service/others02.htm)
