RECOMMENDATION(S):

ADOPT Resolution No. 2016/409 approving and authorizing the Chief Engineer, Flood Control and Water Conservation District (FC), or designee, to impose the annual Drainage Area Benefit Assessments (DABAs) for Fiscal Year 2016/17 for Drainage Areas 67a, 75a, 76a, 520, 910, 1010, and 1010a, Walnut Creek, Oakley, Alamo, Danville, and San Ramon areas. (100% Drainage Area Benefit Assessment Funds)

FISCAL IMPACT:

The proposed annual DABAs will provide approximately $740,000 in funding for drainage maintenance activities in Drainage Areas 67A, 75A, 76A, 520, 910, 1010, and 1010A.

BACKGROUND:

DABA areas are those in which all parcels within each drainage area boundary pay assessments for flood control infrastructure maintenance and repair. Flood control maintenance activities include complaint investigation, facility inspections, ditch and basin cleaning, maintaining right-of-way access, and other general routine drainage maintenance activities. Special drainage maintenance activities, such as bank repairs, are also funded by the assessments. The benefit assessments collected are used only for administration, maintenance, and operation of the Flood Control facilities, within the FC District right-of-way limits.

The annual benefit assessment amount for each Impervious Area Unit (IAU [one IAU equals 1,000 ft2]) is the quotient of the total annual maintenance cost divided by the total IAU’s in the drainage area. The annual benefit assessment for each lot is the product of the number of IAU’s assigned to each lot times the annual benefit assessment per IAU. The annual benefit assessment is adjusted periodically to account for inflation and maintenance needs.

The Board of Supervisors, acting as the governing board of the FC District, provided public notice to all affected property owners prior to the establishment of the initial DABAs. The Board set the maximum assessment rate for each DABA when each drainage area was formed. A maximum reserve fund based on the estimated annual cost of the maintenance services was also established when each drainage area was formed. The purpose of this action was to provide adequate funding for unscheduled maintenance or contingencies.

CONSEQUENCE OF NEGATIVE ACTION:

If the proposed DABAs, for Fiscal Year 2016-2017, are not implemented, routine and special drainage maintenance of flood control facilities in these drainage areas may not occur, which could impair the effectiveness of the flood control facilities in these drainage areas and negatively impact the surrounding watersheds. A significant impact in a watershed could cost the FC District and the County considerable amounts of money to repair and restore the flood control facility and surrounding areas.
