This appears to be a most frequently asked question and possibly a most frequently misunderstood subject in the Mandalay Bay area.

Update October 9, 2014: Just got the final cost for the foundation & slope protection repairs, $152,423.41, down for the estimated $210,000. (saving: $57,576.59) Big thanks to the City of Oxnard and Harbor OffShore and the residents at the locations the work was done for the project coming in under budget! We have had numerous reports about how hard the Harbor Offshore people worked on this and the excellent quality of the work they did on this very important project to extend the life of the Seawalls! Thanks to TranSystems for identifying the need, defining the work and monitoring. Thanks to the City of Oxnard for scheduling, monitoring and keeping us in the loop, and thanks to the residents for being responsive to requests for waivers and extending work hours.

The numbers above reflect the new numbers for slope protection work completed in 2014.

NOTE:It is important to understand that the above numbers do NOT include the additional areas of expenditures from the Waterways Assessment funds like Landscaping & maintenance cost which are not insignificant. The costs for Landscaping & Maintenance for Fiscal year 2013-2014 = $169,316.

Total assessment revenue $450,000 minus Landscaping & Maintenance $169,316 = $280,684 left for Seawall Repairs and maintenance.
NOTE: The assessment referenced here is a round number of the total “waterways” fees collected on property tax bills to homeowners.
