Pre-Existing Swimming Pool For Abandoning Purpose Located at 2210 N.
Laird Street. Santa Ana. Califomia 92706.
Dear Mr. NguyenrMs. Vo
In accordance with the requirements of the City and per your request and authorization.
this certification has been prepared for the demolition and backfilling ol the pre-existing
swimming pool located at Ihe subject site.
We understand that creation of drainage holes along the bottom olthe swimming pool
by puncturing/breaking-out the pool shell bottom has been approved by the City
inspector prior to backfilling the swimming pool.
2. Removal ol the coping. bond beam. and upper portions of the swimming pool shell
side walls has also been performed and approved by the City Inspector.
3. All utility lines serving the swimming pool including electric, gas. and water lines
were terminated./disconnected/removed and plugged/capped in an approved manner.
and approved by the City Inspector.
4. Some concrete chunks ofthe removed coping. bond beam, and swimming pool shell
were placed along the bottom of the swimming pool to be used as a layer of free-
drainage-materials.
5. The regular soil fill materials generally consisted of yellowish brown silty fine sand
with traces of clay. were placed in thin lifts. added water by using a water hose. and
compacted to 9070 relative density by using a Bobcat.
Conclusion:The demolition and backfilling of the pre-existing swimming pool is
considered geotechnically acceptable and suitable for the intended use for landscaping/
non-structuraI purposes.
Note: If a structural object such as a room addition is to be constructed at or near the
su'imming pool backfill area in the future. a qualified geotechnical engineer should be
consulted and a soil repo( should be prepared for provision ol geotechnical
recommendations for foundation design.
If you have any questions or required clarification. please contact this office. This
opportunity to be ofservice is sincerely appreciated.
Very truly yours.---:=-r
