CC 2021-11-09_08i Emergency Storm Drain Repair_251 East GrandMEMORANDUM TO: CITY COUNCIL FROM: BILL ROBESON, ASSISTANT CITY MANAGER/PUBLIC WORKS DIRECTOR BY: JILL MCPEEK, CAPITAL IMPROVEMENT PROJECT MANAGER SUBJECT: ADOPTION OF A RESOLUTION FINDING AN EMERGENCY EXISTS WITHIN THE CITY AND AUTHORIZING CONTRACTING WITHOUT A COMPETITIVE SOLICITATION FOR BIDS FOR THE STORM DRAIN SYSTEM AT 251 EAST GRAND AVENUE PROJECT, PW 2021-12 D ATE: NOVEMBER 9, 2021 SUMMARY OF ACTION: Adoption of the Resolution will allow for immediate emergency repairs to the storm drain system at 251 East Grand Avenue. IMPACT ON FINANCIAL AND PERSONNEL RESOURCES: The FY 2021-22 Capital Improvement Program (CIP) budget includes $410,000 of American Rescue Plan Act (ARPA) funds for repair of the Storm Drain System at 251 East Grand Avenue Project. Staff time will be necessary to coordinate construction activities with the property owner, consultant engineer, and contractors. RECOMMENDATION: It is recommended the City Council: 1) adopt a Resolution pursuant to Public Contract Code Section 20168 finding that an emergency exists within the City and authorizing contracting without a competitive solicitation for bids pursuant to Public Contract Code Section 22050; and 2) Authorize the City Manager, or designee, to execute contracts with specialized contractors for repair of the Storm Drain System at 251 East Grand Avenue Project, PW 2021-12. BACKGROUND: The need to replace a City-owned deteriorating corrugated metal pipe (CMP) located in an easement at 251 East Grand Avenue was identified and included in the FY 2021-22 CIP budget. In response, staff initiated an investigation of potential alternatives and began coordination efforts with the property owner. It was determined that due to extensive deterioration and damage, it would not be possible to fix the deteriorated pipe by lining the existing CMP. A replacement pipe(s) was identified as the most feasible alternative and design efforts commenced. Boring a pipe, or two smaller pipes, parallel to the existing CMP within the existing easement was identified as the quickest (no additional easements Item 8.i. - Page 1 CITY COUNCIL ADOPTION OF A RESOLUTION FINDING AN EMERGENCY EXISTS WITHIN THE CITY AND AUTHORIZING CONTRACTING WITHOUT A COMPETITIVE SOLICITATION FOR BIDS FOR THE STORM DRAIN SYSTEM AT 251 EAST GRAND AVENUE PROJECT, PW 2021-12 NOVEMBER 9, 2021 PAGE 2 required) and least disruptive (the Chevron station can continue to operate as opposed to trenching which would require a temporary closure) alignment. In preparation for the rain event that occurred on October 24-25, 2021, City crews installed a barrier between the existing storm basin and existing CMP inlet to prevent storm water from entering the deteriorated CMP. It was anticipated that, should the basin fill up during the event, it would take the natural drainage course towards Arroyo Grande Creek either by gravity or by pumping operations by City crews. The intent was to preserve the existing CMP as much as possible by preventing any storm water from entering the deteriorating CMP and further undermining the surrounding soil, which causes voids under the pavement and leads to surface depressions and eventually sink holes. However, during the rain event on October 24-25, 2021, when the basin filled above the CMP inlet structure (headwall), the storm water eroded an area behind the headwall where the storm water entered and reflowed through the CMP. This led to areas of further surface depressions which were quickly compacted with additional backfill and asphalt patches by City crews. The emergency approach being proposed will enable the City to mobilize as quickly as possible in accordance with Public Contract Code (PCC) Section 20168 in an attempt to avoid further undermining of the soil by forthcoming rain events and the potential development of hazardous sink holes and closure of the Chevron station’s operations. The proposed work includes plugging and filling the existing CMP and adjacent voids with lightweight cellular concrete, boring a new pipe or two smaller pipes within the existing easement, and constructing two new headwalls at each end of the new pipe(s). ANALYSIS OF ISSUES: Normally, the Public Contract Code (PCC) requires a competitive solicitation for bids on all public works projects. However, PCC Section 20168 allows the Council to adopt a Resolution by four-fifths vote declaring that the public interest and necessity demand the immediate expenditure of public money to safeguard life, health or property. In addition, pursuant to this section and PCC Section 22050, in the case of an emergency, the Council by a four-fifths vote may procure the necessary services to repair a public facility without giving notice for bids. PCC Section 1102 defines an emergency as a sudden, unexpected occurrence that poses a clear and imminent danger, requiring immediate action to prevent or mitigate the loss or impairment of life, health, property, or essential public services. In this case, where capping the inlet headwall proved to be nonviable, there is an imminent danger to public health and safety for the following reasons including, without limitation, the potential for storm water flows and the development of sinkholes caused by voids created by storm water flows inside a collapsed and deteriorated CMP that is located in very close proximity to a gas station.

Therefore, staff will be returning to the City Council with updates as required by the statute. Adopting the proposed Resolution will ratify the emergency authorize staff to execute the appropriate contracts with specialized contractors; and ensure that the contractors will be properly compensated for their emergency response and repair. ADV ANTAGES: Adoption of the Resolution will allow for immediate emergency repairs to the storm drain system at 251 East Grand Avenue without the delays that would occur if the project had to go out to bid, will eliminate a serious threat to public health and safety, and minimize disruptions to the Chevron station’s operations. DISADVANTAGES: None identified at this time. ALTERNATIVES: The following alternatives are provided for the Council’s consideration: 1.Approve staff’s recommendations; 2.Do not approve staff’s recommendations and request further information; 3.Modify staff’s recommendation and approve; or 4. Provide other direction to staff. ENVIRONMENTAL REVIEW: The project is categorically exempt from the California Environmental Quality Act (CEQA) pursuant to Guideline Section 15301(b) for the repair of existing publicly-owned facilities used to provide public storm drain utility services. PUBLIC NOTIFICATION AND COMMENTS: The Agenda was posted at City Hall and on the City’s website in accordance with Government Code Section 54954.2. ATT ACHMENTS 1.
