RE: Structural Impact of Water Retention Area Closer than 10’
Job # 22194 – Lucero Residence, 376 Tenth Street
To whom it may concern:
I have reviewed the groundwater site drainage plan for the proposed structure at 376 10th Street
prepared for Ashlar Homes Builders by Alpha Southeast, Inc, dated 03/3/2022. I have noted the
proximity of the boundaries of the water retention areas to the foundation, that they are approximately
2.5’ and 9’ from the edge of the foundation for the structure. It is my opinion that this proximity will
have no impact on the structural performance of the stemwall foundation planned for this structure
provided that the retention areas are above the zone of influence of the stemwall footings (see TYP.
FOOTING IN PROXIMITY TO POOL for illustration) and that soil conditions meet or exceed requirements
specified in the structural plan of CS: Foundation: Paragraph B and no clay type soils are found on the
site.
If there are any questions or need of further assistance, feel free to contact our office.
