The geotechnical report summarizes subsurface conditions at a site located near FM78 and Lakeview. Three soil strata were identified below 1.5 feet of asphalt and crushed limestone base: [1] stiff lean clay from 0.5-1 feet; [2] stiff to very stiff clay from 1-7 feet; and [3] stiff to very stiff clay with gypsum crystals from 7-15 feet. Approximately 3 feet of clay should be removed and replaced with select fill. Shallow foundations are suitable with a minimum embedment of 2 feet below grade and allowable bearing pressure of 2,000 psf. Total settlement of 1 inch and differential settlement of 0.5-0.75 inches

#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.
