Approximately 3 feet of clay should be removed and replaced with select fill
These conditions will satisfy a Condition C Foundation
*Note: Sample was taken less than 1000 feet away. This is the reason for the initial layer of asphalt in the boring sample.

3. Porous Paver Information
Purchased from Belgard Company, Aqua-Roc Porous Paver will be used.

(in.)
Vehicular Paver 3.15
#8 Aggregate 2
#57 Aggregate 6
#2 Subbase Aggregate 6
To be used in parking stalls, as well as parking lot walkways for foot trafic.
This material will support the stormwater runoff design.
Stormwater runoff will flow under the parking lot to a system of pipes, which will direct the water to a nearby
sewer easement.
This material will also give benefit to our LEED certification goals, and also meets ADA requirements

Asphalt Paving for Parking Areas, Assembly Costs
A vehicular porous paver will be purchased from manufacturer Belgard and used in the parking
stall areas, as well as foot traffic walkways.
For our required dimensions, a purchase price estimate including base aggregates and labor
was given to be roughly $7 per square foot.
