Meeting in regular session on November 21, 2013, the Board approved awarding a contract to Hatch Mott MacDonald Florida LLC (now Mott MacDonald Florida LLC) for the Grande Lagoon Subdivision Project.
In 1972, Grande Lagoon Subdivision started development, with Grande Lagoon West and Grande Lagoon Lakes being recorded in 1974, and Grande Lagoon South in 1978. These developments and Chanticleer made up the Grande Lagoon Subdivision project evaluation area.
The Gulf Beach Highway drainage system drains through the Grande Lagoon drainage systems, easements, ponds, and/or lakes. The lake systems within the Grande Lagoon Drainage area are privately owned and maintained by the homeowners association. However, the roadways and drainage systems are county-maintained and they discharge, in part, to these private lakes. Following the June 2012 storm events, (Hatch) Mott MacDonald Florida LLC was contracted by Escambia County to provide a drainage study and written report of findings with recommended solutions. This report was completed in January 2013 and reviewed with representatives from the Grande Lagoon Homeowners Association in June 2013.
Change Order #1 added $35,081 from the April 2014 storm event, to allow (Hatch) Mott MacDonald Florida LLC to prepare a Preliminary Engineering Assessment and cost estimate to address infrastructure damaged by the storm and additional design for recommended enhancements to key system components for future stability. The storm damage costs have been submitted to the Federal Emergency Management Agency (FEMA) for reimbursement and are identified as Phase I.
Change Order #2 added a project number for the April 2014 storm portion of the purchase order (Phase I) and Change Order #3 added time to the contract.
This Change Order, #4, in the amount of $20,915, is for collecting additional topographical survey, to analyze hydrological data for finalizing 100% design, and for limited construction and bidding assistance, and as-built certification to complete originally-planned improvements that were delayed by the 2014 storm. This final phase is identified as Phase 2.
