Discussion:
On July 24, 2005 within the vicinity of 74-240 Goleta Avenue, significant street
flooding occurred as a result of a storm. City crews were dispatched to
investigate the reasons for flooding and encountered a blockage in the pipe that
they were unable to unclog.
Because of the potential for continued flooding and damage to residences,
engineering staff acquired the services of Houston Harris to determine pipe
capacity, current conditions and the potential for pipe failure. The inspection
found a 15-foot segment of pipe which was heavily blocked by concrete debris.

INTEROFFICE MEMORANDUM
To: Carlos Ortega, City Manager
From: Mike Errante, P.E., Director of Public Works
Date: August 9, 2005
Subject: Emergency Work
74-240
On July 24, 2005, within the vicinity of :72 249 Goleta Street, significant street flooding
occurred as a result of a storm. For your review we have attached a picture of the flooding.
Staff inspected the storm drain system in order to investigate the reasons for flooding. City
crews were then dispatched to clean the pipe. They encountered a blockage in the pipe
that they were unable to unclog.
Because of the potential for continued flooding and damage to residences, engineering staff
acquired the services of Houston Hams to further investigate the flooding concern and
determine:
• Pipe Capacity
• View current pipe conditions
• Engineering assessment of potential pipe failure
On August 5, 2005, Houston Harris used chain flails, root saws and high-pressure nozzles
to remove all the debris. In addition, they video inspected the storm drain lines to determine
if they were unclogged and cleaned, or if additional obstructions were present. The
inspection found a 15' segment of pipe to be heavily blocked by concrete. Attached for your
review are the video inspection images of the concrete debris.
Anticipating further storm events, engineering staff recommends that the pipe be repaired
as soon as possible. Therefore please approve this emergency work and authorize
payment to Coachella Valley Construction Services for an amount not to exceed $25,000.
