Soil Borings were performed by Mike’s Boring and Coring, LLC on December 12, 2017 at locations recommended by Engineering Ventures. A 4” diameter vertical PVC pipe was installed and capped during the boring work for the infiltration test. The elevation of the bottom of the 4” diameter PVC was approximately 206.0 (Approximately 6’ below existing grade at the infiltration testing location). A Borehole Infiltration Test was performed at the location, using Section 4.3.3.2.5 of the Vermont Stormwater Treatment Standards, latest revision as a guideline. The test involved filling the 4” PVC with 24” of water, and monitoring the water level by measuring the drop from the top of the casing for 30 min. This procedure was repeated until a stable infiltration rate was obtained, with the 4” PVC being refilled to be at the initial 24” water level mark. The results of the test performed are shown in the following table: Time Interval Initial Height from Top of Casing Final Height from Top of Casing Measured Drop per 30 min Measured Drop per hour 10:00– 10: 30 3’‐8.5” 4’‐0.75” 4.25” / 30 min. 8.5”/hr 10:30 – 11:00 3’‐8” 3’‐8” 0” / 30 min 0”/hr 11:00‐11:30 3’‐8” 3’‐8.5” 0.5” / 30 min 1”/hr 11:30 – 12:00 3’‐8.5” 3’‐8.5” 0” / 30 min 0”/hr 12:00 – 12:30 3’‐8.5” 3’‐8.5” 0” / 30 min 0”/hr 12:30 – 1:00 3’‐8.5” 3’‐8.5” 0” / 30 min 0”/hr 1:00 – 1:30 3’‐8.5” 3’‐8.5” 0” / 30 min 0”/hr 1:30 – 2:00 3’‐8.5” 3’‐8.5” 0” / 30 min 0”/hr 2:00 – 2:30 3’‐8.5” 3’‐8.5” 0” / 30 min 0”/hr Stabilized Average Measured Infiltration Rate = 0” / hr S:\PROJECTS\0‐2017\17594 So.
