2.	CONSIDER EXPENDITURE TO CONTRACT WITH THE CALIFORNIA CONSERVATION CORPS FOR FALL 2018 VEGETATION MANAGEMENT AND TO REMOVE CONCRETE AT RANCHO CAÑADA (No CEQA action required per CEQA Guidelines Section 15168 Program EIR)
Meeting Date:			August 20, 2018	Budgeted:	Yes
From:			David J. Stoldt	Program/	Riparian Mitigations
			General Manager	Line Item No.:	2-1-4
Prepared By:			Thomas Christensen	Cost Estimate:	$18,311
General Counsel Approval: N/A
Committee Recommendation: The Administrative Committee reviewed this item on August 13, 2018 and recommended approval.
CEQA Compliance: No CEQA action required per CEQA Guidelines Section 15168 Program EIR. The Board certified the Carmel River Management Plan Environmental Impact Report on October 29, 1984.

SUMMARY: The Board will consider authorizing staff to contract with the California Conservation Corps (CCC), which will provide a crew of approximately 12 workers (6 days) to help District staff carry out vegetation management activities on the Carmel River during the fall of 2018. Vegetation management this year will involve cutting, removing, and dragging large tree limbs out of the river bed and removing debris from the channel in preparation for potential high winter flows. The amount of work required this year warrants the use of CCC workers. This program is conducted in accordance with the District’s “Guidelines for Vegetation Management and Removal of Deleterious Materials for the Carmel River Riparian Corridor.”

In addition, the CCC will help District staff use jackhammers to break up and remove a concrete bridge pier and deck associated with a collapsed bridge that is lying in the bed of the Carmel River on former Rancho Cañada Golf Course property. This concrete will also need to be carried by hand up and out of the river bed.

CCC Labor Cost = $15,840

Removal of the concrete bridge pier and associated deck will require rental of a compressor trailer, jackhammers, hoses, points, and a cutoff saw.

Equipment Rental Cost = $1,471

In addition, as the District breaks up the concrete, it is possible that large steel reinforcing beams may be encountered within the bridge pier or deck. The District may need a specialist to come and cut the steel with a torch. Carmel Valley Iron Works stated that they could come to the site and cut any large steel beams into smaller sections so they could be carried out.

Steel Cutting Cost = $1000 ($200 for set up and $100 per hour, only if needed)

RECOMMENDATION: Staff recommends the Board authorize the General Manager to enter into an agreement with the CCC to assist with Vegetation Management and Concrete Removal, rent equipment for concrete removal, and hire Carmel Valley Iron Works for cutting of steel beams for a not-to-exceed amount of $18,311.

DISCUSSION: The District plans to perform in-channel vegetation management and concrete removal along the Carmel River in September and October of 2018. Large trees that have fallen across the river are cut into sections to reduce the risk of debris piles and erosion events during winter flows. Erosion can occur if high flows are directed away from the center of the channel by vegetation and debris dams. In addition, it is anticipated that it will take at least four days to break up the concrete bridge pier and deck in the channel bottom and carry the concrete out of the channel to the truck by hand. It is important to note that the removal of the concrete pier and deck is part of a mitigation offset that will allow the new screen to be placed in the channel bottom for the Sleepy Hollow Intake Project.

California Environmental Quality Act: The removal by staff of “…snags and other debris from the [Carmel River] channel…” is described as part of the implementation of the Carmel River Management Plan (p. 41, CRMP). The District approved the CRMP as a project with the adoption of Resolution 84-26 on October 29, 1984.

IMPACT TO STAFF/RESOURCES: Funds for this project are included in the FY 2018-19 budget under “Riparian Mitigations,” line item 2-1-4 Address Vegetation Hazards and Remove Trash, Account 24-03-787040.
