Prior Board Motions:
On December 5, 2017 the following motion carried:
1. Prioritize the flooded homes on the basis of severity of the damage and
determine willingness to sell.
2. If any sub divisions with flooded homes have an option for preventing future
flooding that is less costly than the acquisitions of homes, then select that
option.
3. It is not necessary to permanently protect an individual road segment from
the possibility of flooding. Pursue most cost-effective options to provide
access during flood events.
4. Analyze remaining County flood issues and incorporate findings into existing
priority list.
5. Meet with St. Johns and Suwannee River Water Management Districts to
identify criteria for cost sharing opportunities. Update project list and
determine if there are any other local or state funding opportunities.
6. To refer to OMB to bring back to the Board prior to the budget deliberations
funding options that would include bonding up to one half of the current
Stormwater Assessment and or special assessment districts or MSBU option
based on benefits specific to watershed basins.
7. Authorize the hiring of Consultants to assist with the process.
On January 23, 2018 the following motion carried:
1. Authorize staff to move forward with priorities 1 through 4, including consultant assistance for developing final plans, and finalize grant applications for State & Federal grants and negotiate purchase and sale agreements with willing sellers at fair market value in the Robin Lane Subdivision and Hills of Santa Fe according to the following priority order:
1.Robin Lane
2.Hills of Santa Fe/Meadowbrook
3.Hayes Glen
4.Pine Hill Estates
2. Instruct staff to draft language for use of funding through next year’s stormwater assessment for fiscal year 2019 and develop a plan for presentation to the Board before December of 2018 for a
Tuesday, January 23, 2018 - 5:00 P.M.
potential special assessment district that will begin in fiscal year 2020.
3. To use as the first source of funding the stormwater assessment maintenance portion with a commitment to repay this fund from other available sources including future grants, future assessments, or special assessment districts. Additional funds needed for this fiscal year would come from reserves.
4. To schedule a Public Evening Meeting within 120 days to discuss Stormwater basins affected and possible assessment districts. The meeting for the subdivisions of Robin Lane and Hills of Santa Fe will be within 30 days. The boundaries established for public notification will be generous including the watershed.
On February 20, 2018 the following motion carried:
1. To instruct staff to pursue alternative permanent easements for emergency access and return to the Board in 90 days.
2. Authorize staff to hire the necessary consultants utilizing gas tax funds.

Background:
Following Hurricane Irma, Public Works Staff pursued Board direction to apply for grants to mitigate flooding in priority areas and to perform maintenance activities to reduce flooding. Since then several locations have been improved. Most locations where pumping has historically occurred after flooding events have been equipped with permanent discharge piping. This has allowed faster deployment of pumps. The locations include Robin Lane, Red Lobster Basin, Sunningdale, SE 35th Street Basin, and Hayes Glen. During and after Hurricane Elsa these systems were very helpful to Public Works and to the residents near these locations. For example, the improved pumping at Sunningdale allowed the basin to be drawn down further before the storm and maintained the water level such that no homes were flooded. At Robin Lane, where nearby floodplains exceeded levels reached by Hurricane Irma, Public Works was able to re-open the entrance road in just over 24 hours as compared to nearly a week with Irma.
Public Works is making a request to purchase several items and materials to prepare for future flooding events. These are:
1. Acquire five (5) additional pumps to be dedicated to or support pumping at priority flooding areas and Countywide as needed. The county will procure the pump from a Cooperative Purchasing Agreement per Procurement Code 22-3.302(12)
2. Two metal storage buildings to properly care for all of the pumping equipment to be constructed at the Public Works Compound in Hague. The county will request approval of the Emergency Certification Form attached, per Procurement Code 22-3.302 (16)
3. Materials to install permanent discharge piping at Emerald Woods, Hills of Santa Fe, and Pine Hills. The county will use the Annual Bid 20-42 Drainage Infrastructure per pricing, conditions and specification of the solicitation.
4. Purchase 5 additional two-way radios and 20 car chargers. The county will procure the radio’s via Sole Source certification previously approved by the BOCC per Procurement Code 22-3.302(28)
The presentation also shows the difference in cost of the improvements made by Public Works compared to the costs for the improvement concepts in the 2010 Stormwater Master Plan.
