Material Balance Note

We estimate there are approximately 320 to 400 tons of material on-site, which is equivalent to roughly 200 to 267 cubic yards. We will make use of this material to balance the site and minimize trucking. However, based on the desired finish grade of the parking area to the north of the ADU and the basketball area, additional material trucking and disposal may be required. If the client agrees to the estimate, we will take a GNSS measure of the existing stockpile to confirm whether additional trucking hours are necessary.
