Dear Mr. Osorio:
In accordance with the requirements ol the City and per your request and authorization,
this certification has been prepared for the demolition and backfilling ollhe pre-existing
swimming pool located at the subject site.
We understand that creation of drainage holes along the bottom of the 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 of the coping. bond beam. and upper portions ol the swimming pool shell
side walls has also been performed and approved by the City lnspector.
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 pieces of demolished pool shell side walls, coping and pond beam
were placed along the bottom of the swimming poo[.
5. The regular soil fill materials generally' consisted of mixture of yellowish brown and
grey/dark grey silty fine sand and clay. were placed in thin lifts. added water by using
a water hose, and compacted 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
purposes.
Note: Ifa structural object such as a room addition/ADU is to be constructed at or near
the su'imming poot backfill area in the future. a quatified geotechnical engineer should be
consulted for provision of geotechnical recommendations for foundation design.
Very truly yours,
