In accordance with your authorization, Cobalt Geosciences, LLC has prepared a plan review letter
for the project. We have reviewed the provided civil plans by Interlaken Engineering and Design,
PLLC dated July 28, 2023.
The plan shows the locations of dispersion devices and other stormwater systems. We note that
the driveway will be surfaced with permeable pavers with a slope toward the structure. There is a
drain to be located between the driveway and residence, directing runoff to the adjacent
dispersion trench. Provided the drains are constructed properly and in accordance with the
approved plans, this is a suitable and feasible system.
We should be on site to verify aspects of the construction. These include but are not limited to
soil bearing for footing areas, dispersion trench placement, foundation drainage placement, fill
compaction (if utilized), slab on grade preparation, and any temporary excavations.
Sincerely,
Cobalt Geosciences, LLC
