TO: Mayor Haggerton

FROM: _1 Public Works Director
DATE: February 9, 2011
SUBJECT: APW /APE Sewer Repair Feb 2011
Project No. 91140202
Resolution Declaring an Emergency
ISSUE
Approve Resolution declaring an emergency that authorizes City staff to expedite repair of
the APW /APE (Andover Park W /Andover Park E) Sewer Repair Feb 2011 Project.
BACKGROUND
On February 3, 2011, a break in a 12 -inch waterline was discovered on Andover Park West
just south of Upland Drive. After the waterline was repaired, sanitary sewer manholes were
inspected and it was determined that the 12 -inch sewer system had also been damaged.
Repair of the broken sewer main was attempted, but due to the presence of wet, sandy soils
the repair was not able to be completed. The poor soils caused an existing manhole to shift,
which damaged two additional sewer pipes that were connected to it as well as undermining
the pavement on Andover Park West. Andover Park West had to be completely closed to
traffic for the duration of the repairs.
ANALYSIS
Approve the Resolution which declares an emergency and authorizes Public Works to
immediately construct repairs to the damaged water and sewer system by a construction
contract exempt from competitive bidding.
This project has grown in size and complexity and repairs are being constructed over the next
week. Dewatering is required for two days before deep excavation for the sewer system can
begin. The first step will be to reset the sewer manhole and then replace up to 60 feet of
sewer main in each direction. A new manhole will also need to be installed behind the
sidewalk on the sewer line to the east. Minor repairs at Sewer Pump Station #2 will be
necessary along with pavement restoration.
RECOMMENDATION
The Council is being asked to approve the Resolution declaring an emergency for the
APW /APE Sewer Repair Feb 2011 Project and consider this item at the February 28, 2011
Committee of the Whole meeting and subsequent March 7, 2011 Regular meeting.
