General Counsel Approval:  N/A

Committee Recommendation:  The Administrative Committee reviewed this item on June 12, 2017 and recommended approval.

CEQA Compliance:  This action does not constitute a project as defined by the California Environmental Quality Act Guidelines section 15378.


SUMMARY:  Staff proposes to enter into an agreement with Balance Hydrologics, Inc. for analysis and design of the Lower San Carlos Restoration Project in the Carmel River channel downstream of Rancho San Carlos Road Bridge.  Significant streambank erosion occurred during February 2017 storms that produced high flows.  Work would include analysis of flooding, shear stress analysis, and design bank stabilization work along about 400 feet of the river channel.


RECOMMENDATION:  Authorize the General Manager to enter into an agreement with Balance Hydrologics, Inc. to provide design services for a not-to-exceed amount of $56,500.  Approval of this item is contingent upon approval of the Fiscal Year 2017-18 budget presented at the June 19, 2017 meeting.  This item is contingent on approval of the FY 2017-18 budget by the Board.


DISCUSSION:  The reach of the river downstream of Rancho San Carlos Road has been subject to instability and minor erosion for several years.  High flows in February 2017 eroded the south bank and removed several large cottonwoods from a 400-foot long portion of the river in one of the last remaining mature riparian forest areas along the river.  Future high flows could destabilize the area downstream, which would threaten homes on the north side of the river and Hacienda Carmel, a retirement community with about 300 units.


IMPACT TO STAFF/RESOURCES:  Funds for this project are included in the FY 2017-18 budget under “Protect Environmental Quality,” line item 2-2-1-A Work at lower San Carlos Restoration Project, Account 35-03-789590.
