SUBJECT: Adopt a Resolution Authorizing the City Manager to Appropriate Additional Funds in the Amount of $20,000 from Sewer Replacement Fund 611 for the Water Pollution Control Facility (WPCF) Effluent Pond Weed Removal Project No. 07630, and Award a Contract to McNabb Construction Inc., to Implement the Project in an Amount Not-to-Exceed $220,000
RECOMMENDATION
That Council adopts a resolution (Attachment II) authorizing the City Manager to appropriate additional funds in the amount of $20,000 from Sewer Replacement Fund 611 for the Water Pollution Control Facility (WPCF) Effluent Pond Weed Removal Project No. 07630 and to award a contract, in a form to be approved by the City Attorney, to McNabb Construction Inc., to implement the Project in an amount not-to-exceed $220,000.
SUMMARY
The WPCF complies with the Alameda County mosquito abatement ordinance by removing weed growth in the water storage ponds. There are seven (7) former oxidation ponds located at the site. An area of approximately 2 acres or 80,000 square feet (Attachment III) of the ponds are currently covered by vegetation (weeds). Approximately 60,000 square feet of vegetation will need to be removed from Pond No. 3 and approximately 20,000 square feet from Pond No. 7 (Attachment V).
This project is for weed removal, pond liner repair and weed disposal. Additionally, approximately 28,000 square feet of vegetation will need to be removed from the existing stormwater channel (See Attachment IV).
BACKGROUND
The City’s current Capital Improvement Program (CIP) includes funding for WPCF Effluent Pond Weed Removal, which is presented annually. This type of service is needed to prevent overgrowth of vegetation and accumulation of debris.
DISCUSSION
For this project, the bid process attracted five (5) contractors to visit the site located at WPCF for a pre-bid meeting and walk-through. This resulted in one (1) bidder, McNabb Construction Inc., submitting the only bid for the scope of work presented for this project. The bid received was in the amount of $398,874. Given that only one bid was received, staff reviewed the scope of work with the contractor and was able to negotiate the same services at a reduced cost of $220,000.
ECONOMIC IMPACT
This project will have no direct impact on the local economy.
FISCAL IMPACT
Project 07630 has a current budget of $200,000, which is reflected in the Adopted FY22 CIP. Staff recommends appropriating an additional $20,000 from Sewer Replacement Fund 611 in Project No. 07630 for a revised Project budget of $220,000. The Fund has sufficient balance to support this appropriation. With these funds, staff recommends awarding a contract to McNabb Construction, Inc., in an amount not to exceed $220,000.
STRATEGIC ROADMAP
This agenda item is a routine operational item and does not relate to one of the Council’s six strategic priorities as outlined in the Council’s Strategic Roadmap.
SUSTAINABILITY FEATURES
The work for this project consists of removal of approximately 2.0 acres of emergent aquatic vegetation in Oxidation Ponds No. 3 and No. 7. This includes removal of approximately 28,800 square feet of emergent aquatic vegetation in the stormwater channel. Emergent aquatic vegetation includes cattails, bulrush, tules and other pond vegetation in the area. The vegetation shall be completely removed, including the roots, using methods that will not dig into and or damage the clay liner in the ponds.
PUBLIC CONTACT
Contract and performance of these services requires no public contact.
NEXT STEPS
If approved, staff will appropriate an additional $20,000 from Sewer Replacement Fund 611 for the WPCF Effluent Pond Weed Removal Project 07630, and will award a contract to McNabb Construction, Inc., in an amount not-to-exceed $220,000.
