FUNDING REQUIREMENTS:
Sufficient funding is available in the current Capital Improvement Program budget for the
award of this contract. The proposed project will be expensed to Account No. 13801-
980000-20X12 (Environmental Contributions) for the Big Canyon Restoration Project —
Phase 2A project.
The City and Newport Bay Conservancy (NBC) have been working together cooperatively
on a plan to restore the Phase 2A area of Big Canyon Nature Park. NBC has been
awarded two grants totaling $1,688,731 to fund the implementation of the Phase 2A
restoration.
Proposed fund uses are:
Vendor
Environmental Construction, Inc
Environmental Construction, Inc.
On -Call Inspection Services
On -Call Geotechnical Services
Purpose Amount
Construction Contract $ 985,348
Construction Contingency $ 147,000
Inspection Services $ 99,000
Geotechnical Servcies $ 5,000
Total: $ 1,236,348
Staff recommends establishing $147,000 (approximately 15 percent of ECI bid) for
contingency purposes and unforeseen conditions associated with construction.
Pursuant to the terms of an agreement with NBC, the proposed FY 2020-21 Capital
Improvement Program Budget will include an appropriation of $100,000 from the Upper
Newport Bay Restoration Fund, a tidelands trust fund designated for construction of
improvements that benefit the Upper Newport Bay. These funds will cover any auxiliary
tasks or improvements such as trail improvements, or other unforeseen and non -grant
eligible costs associated with the project.
DISCUSSION:
The proposed Big Canyon Restoration Project — Phase 2A straddles Big Canyon Creek
and covers 11.3 acres in the central portion of Big Canyon Nature Park (see attached
Location Map). The project will remove and replace existing invasive exotic vegetation,
stabilize the creek banks and restore connectivity with the floodplain, restore riparian
habitat and create a mosaic of native and (fire and pest) resilient habitats that promote
biodiversity and healthy ecosystems.
A 6.3 -acre portion of the project area is populated almost solely by non-native Brazilian
Pepper Trees ("Clearing and Grubbing" area). The restoration of this area includes
complete removal of the pepper tree grove, including root systems, with subsequent
replanting with native plants. The other 5.0 -acre portion of the project includes Brazilian
pepper trees intermixed with willows and other native vegetation. In these areas, Brazilian

pepper trees, invasive plants, and willows infected by the polyphagous pothole borer will
be selectively removed ("Select Removal" areas).
On February 11, 2020, the City entered into an agreement where NBC will use the grant
funds identified above to reimburse the City for costs associated with hiring a construction
contractor, geotechnical consultant, outside contract inspectors, and other consultants or
inspectors as needed. In return, City agrees to manage the construction.
At 10:00 a.m. on May 15, 2020, the City Clerk opened and read the bids for this project:
The City received six bids for this project. The low bidder, Environmental Construction,
Inc. (ECI), possesses a California State Contractor's License Classification "C27", as
required by the project specifications. ECI has successfully implemented several
important projects for the City including the Buck Gully Restoration Project (2012) and the
Big Canyon Phase - 1 Project (2017).
The low bid by ECI is 18 percent below the Engineer's Estimate of $1,200,000. The six
bids show a good spread with three bids below the Engineer's Estimate and three bids
above. The current economic downturn may have been a factor in the more competitive
bids.
Pursuant to the Contract Specifications, the Contractor shall have 80 consecutive working
days to complete all construction tasks within the "Clearing and Grubbing" areas. An
additional 30 consecutive working days is allowed to complete removals within the "Select
Removal" areas. The Plant Maintenance and Establishment period is 120 consecutive
calendar days, which commences after the Engineer has determined the work complete
in in the Clearing and Grubbing areas.
Agency permits for the project prohibit commencement of work until after the bird -
breeding season. NBC will hire a biologist to inspect the project site for nests. If no nests
are found, it is possible that construction could start mid-August. An early project start is
desirable as it would be possible to be substantially complete with the project tasks before
the end of the year ahead of the typical storm seasons when construction would need to
cease due to muddy conditions on site.
Portions of the project are so densely vegetated that neither City staff nor the contractor
has been able to specifically scope the level of effort to remove pepper trees and perform
grading along the creek. A 15% contingency is recommended to cover additional costs
