Turf reinforcement for overflow parking

[sketchhwyman]

I am designing a perking lot for a church. For their weekly services they need about 35 parking spaces. They will also need an additional 25-30 spaces for larger events they hold maybe 5 times per year. Originally, we were just going to provide a paved lot with 65 spaces, but for various reasons we want to investigate a reinforced turf concept for the overflow parking.
I have looked at various proprietary products such as EcoGrid, but it seems as though there is no cost savings over just paving the area. My client is open to the idea but they will not pay extra for it. Does anyone have any experience with a design using a regular geotextile bedding underneath turf for overflow parking? It would be lightly used but it does need to hold up.

I've used it before for a fire truck access way at a university. They needed a fire lane able to support a fire engine around a dorm, but didn't want to build a road and ruin the asthetics. It worked great.

There are a couple of different products you can use. Heavy loading like above, light loading like you'll use for overflow parking.

My guess is the 'grasscrete' will be less expensive, but not drastically so and require landscape maintenance as well. All depends what your client puts at a premium.

Try looking at these guys, I found some literature in my stack of supplier crap I seem to collect.
