  • Pavement Evaluation - Pavement evaluation is a key step to determine the type of distress of the pavement.  Determining the cause of the distress determines the potential maintenance actions.  We use our technical knowledge and experience to provide a comprehensive maintenance plan.  We have the technical knowledge and construction experience to provide specifications for the maintenance work as well as inspection of the work.  Our experience and technical knowledge also provides a solid base for determining current condition assessments and replacement costs for reserve studies. See
  • Drainage System Investigations - Flooding, erosion, pavement failures and slow draining retention systems are all potential issues of a drainage system that is not functioning properly.  Changed drainage conditions in the drainage area including offsite flows could contribute to increased flows in a  system  that was not designed for these flows.  We have the technical experience to conduct an analysis and develop solutions if needed.
  • Inspections - Inspection of site and building systems are often necessary to get to the cause of a problem.  Some inspections may require the need of a specialist to find the root cause.  FDRS has the professional resources to engage those services or identify those resources for direct contact to an association.

Hi Barbie,

I want to thank FDReserve Studies for their report.  The Report was complete, concise, and timely.  Their repair and maintenance estimates were even within 3% of actual contractor estimates!  The Report provided us with an authoritative framework from which we were able to create a Reserve Model.  This Reserve Model utilized our most recent prior 10-years of actual costs and projected out 30-years.  From this model we are now able to create “What-If” scenarios to determine the perfect balance of Annual Dues, Reserve Amounts, annual maintenance expenses, and recurring repairs.

The Report not only provided industry standards from which we can rely, but they also identified a risk that was previously unknown, allowing us to take corrective action before it became a major expense.  This alone paid for their service, even though they were the least expensive firm identified from our competitive bidding.

As an added benefit, they helped us interpret the CC&Rs to ensure that we understand what was the HOA’s responsibility versus the Homeowner’s.  This nuance was elusive before their clarification, but critical for the Board’s decision making. 

I highly recommend all HOAs engage FDReserve Studies!

Regards, Don
