Approve Emergency Repairs previously authorized by the Interim City Manager, per Purchasing Policy requirements.

Funding for this emergency project (totaling approximately $155,000) is available in the Water & Sewer Fund (Account #441-5165-533-461 0), and in the Stormwater Fund (Account #443-5300-541-461 0) .

1) Memo from Russell Ferlita, Ph.D., P.E., Section Engineer I Utilities & Traffic to Douglas Hutchens, Interim City Manager;· dated February 02, 2017 requesting emergency authorization;

2) Initial and revised cost estimates from Rowland, Inc., along with Attachments 'A' & 'B', and initial Purchase Order, dated February 8, 2017.

A failure in the sanitary sewer system occurred in an 18" sanitary sewer line, located at the comer of Patricia A venue and Bel trees Street. The failure was detected as a result ofundermining of the adjacent sidewalk and surrounding ground, causing the area to begin to collapse. Due to the proximity of the adjacent roadway travel lane, this was deemed to be an emergency repair for obvious safety concerns to the public. Investigation of the failure revealed settled pipe segments and a

manhole, failing pipe lining, and loss of integrity of the line leading to Inflow and Infiltration (1&1) into the sanitary sewer system. The existing manhole and sanitary sewer pipes in this area are deep, and beyond the capabilities of City staff and equipment to safely address, Rowland Inc., was contacted in order to make the necessary repairs on an emergency basis.

Once the emergency repair work commenced and the associated maintenance of traffic (MOT) was established, City staff realized the benefit in optimizing the already in place sanitary sewer by-pass pumping and MOT in order to limit future interruptions to traffic and adjacent businesses. City staff approved the installation of a pipe liner on an unlined segment of clay sanitary sewer pipe along Beltrees, which was planned for the new future as part of the City's ongoing pipe lining plan to address I&I. Installation of this segment of liner during this emergency repair allowed the City to prevent an additional future road closure and need for by-pass pumping; thus saving time and money.

While the emergency sanitary sewer repairs were underway, it was discovered that a storm sewer culvert connecting two storm structures in the work area had failed. As the contractor was already in place to make the sanitary sewer repairs, City staff approved the removal and replacement of the failed segment of storm sewer.

These repairs of the sanitary and storm sewer pipes, totaling approximately $ 155,000, will increase the safety and reliability of these systems and help prevent future fa ilures at this locati on.

Staff respectfull y requests the Commissions concurrence of these emergency repair activities and authorizations.

Patricia Avenue and Beltrees Street Sanitary Sewer Failure

A leak in two 18" sanitary sewer main segments and failure of the corresponding manhole was detected at the comer of Patricia Ave. and Beltrees St. (Attachment A). Video imaging of the sanitary mains revealed cracking and settling of the unlined clay pipe, failure and settling of the lined clay pipe, and settling of the manhole connecting the two sanitary sewer mains. These failures have caused washing out of the surrounding soil and caving of the sidewalk immediately adjacent to the roadway, in this area. The repairs will require replacing the manhole, replacing damaged and failing sections of the 18" sanitary sewer mains, protection of the roadway section, and restoration of the area upon completion of the work. Repairs will require redirection of traffic and bypass pumping in the immediate area. The estimate of total cost for the emergency repair is $117,034, which exceeds the amount of$25,000 (see attached estimate).

According to the City's Purchasing Agent, since the cost of these repairs is in excess of $25,000, Purchasing Policy requires a memo of justification for this emergency action, and that it be approved by the City Manager.

Therefore, please review this request, and if acceptable, acknowledge your approval by signing below:

Thursday, February 23, 2017 10:07 AM Ferlita, Russell Ken Rowland RE: Quote - Layne CIPP Liner.xlsx

Ken and I went over where we are at so far and what It will take to complete. we are going to be at approx. 155K total, that Is adding the Layne pipe lining, test plug replacement and couple days extra MOT, Bypass etc.. There has been A LOT of extra cables that were not located which has slowed us down a bit. If the pipe to the west Is

good to connect to as seen on the TV report, I do not foresee any additional costs. If we cannot connect prior to getting into the road we may have additional road work.

Thank you
