In accordance with your authorization, Cobalt Geosciences, LLC has prepared a plan review letter
for the proposed development.
We have reviewed the provided civil plans by IECO dated May 3, 2022 with updates July 2023.
We have no specific comments at this time.
The proposed pipe anchors (concrete blocks keyed into native soils) appears to be suitable from a
geotechnical standpoint. We should verify final locations and subgrade soil conditions for these
features.
We should be on site during construction to verify soil bearing of foundation areas, stormwater
facility placement, temporary excavations, building locations, erosion control, any subsurface
drainage placement, and soil compaction.
Please contact us if you have any questions.
Sincerely,
Cobalt Geosciences, LLC
