Three ten -foot auger holes were investigated and found to contain soils consistent with those in the surrounding area, which are capable of supporting loads not to exceed 2500 pounds per square foot. One fifteen -foot probe penetration test was performed to determine the density of the existing soil. These tests, performed in compliance of Section R401.4 of the 2017 Florida Building Code, Residential, provided sufficient evidence that the underlying soils will support the proposed structure. Per the attached SCS Soil Survey information, the soils are consistent with and classified as Paola Sand and are not expansive, compressive or otherwise of questionable characteristics. Therefore, per Section R401.4, additional soil tests in accordance with FBC 1803.6 beyond this preliminary report are not necessary 11111111 Respectfully submitted, Richard Boyette, FL PE #424f Vice President Attachments: Log of Borings SCS Map & Soil DATE: July 21, 2020 File # 22260 B .D0 ... p YF \,\G E N5 [1' 42485 STATE OF =U scrip#�T'N LOG OF TEST BORINGS - 07/20/20 Depth Auger Hole 1 Auger Hole 2 Auger Hole 3 Pen Hole 4 Depth N Remarks 1 DARK BROWNISH GRAY MIXED SAND DARK BROWNISH GRAY MIXED SAND DARK BROWNISH GRAY MIXED SAND DARK BROWNISH GRAY MIXED SAND 1 5 4 5-4 5-5 2 2 3 3 LIGHT BROWNISH GRAY SAND LIGHT BROWNISH GRAY SAND LIGHT BROWNISH GRAY SAND LIGHT BROWNISH GRAY SAND 4 4 5 5 LIGHT YELLOWISH BROWN SAND YELLOWISH BROWN SAND YELLOWISH BROWN SAND 6 YELLOWISH BROWN SAND 6 7 LIGHT YELLOWISH BROWN SAND 7 8 8 LIGHT YELLOWISH BROWN SAND LIGHT YELLOWISH BROWN SAND 9 LIGHT YELLOWISH BROWN SAND 9 10 10 Water Table: NOT FOUND LIGHT BROWN SAND 11 12 13 14 15 TERRAIN NOTES Site Elevation: NOT GIVEN: NGVD Drainage Status: Natural Vegetation: None Construction Status: Pad Hole Status: (X) Hole remained open ( ) Hole closed SCS Soil Classification: Paola Sand File #22260 SPECIFICATION REFERENCES 1.

(Mod Proctor Test #1) Verification Statement This statement shall serve as verification that the soil beneath the proposed structure has been tested in accordance with Section R401.4 of the 2017 Florida Building Code, Residential edition. The tests were conducted from the existing grade. Density tests were taken at a minimum of three (3) locations throughout the total depth of fill. The depth of fill was approximately 2_5 feet. The foundation setbacks were based on information furnished by the client, at the time of testing. Based on the location and depths tested, we verify that the fill has been compacted to a minimum of 95% of the maximum dry density as determined by ASTM D-1557 and that the minimum soil bearing value beneath the proposed foundation area is 2,500 pounds per square foot.
