Falls Water Company Application for Approval of Three Capital Projects
Data Request Response

Request No.: FLS-W-21-01 IPUC DR 4

REQUEST NO. 4: Please explain why the developer did not address runoff in the
Taylor Mountain subdivision and why the Company believes it is reasonable to assume
the costs of building a runoff containment solution? Application at 4.

Response:
The Company did not own the water system at the time the development was being
built. Bonneville County has the final approval of development design in the
unincorporated areas of the county. The earlier divisions of the development did not
have provisions for storm drainage. So, it can only be assumed that the county
continued with the original design as the development grew.
The Company is aware of other parcel owners that historically have had storm and
snow melt run-off issues. It is not uncommon for such events to create flooding issues
for the homeowners. Homeowners with frequent problems have used French drains
and other methods to correct the problems. If these measures fail, the homeowner still
may experience flooding.
The Company seeks to minimize potential liability to itself (and its customer base) by
installing the run-off containment unit.
