How do I develop in parcels with High Risk Flood Zone designation where structures are not raised 18" above Base Flood Elevation?
In addition to the required plans for the project, forms and fees, you will have to produce documentation to validate the development improvement in the High-Risk Flood Zone location.
Documents required at the time of development submittal in High Risk Flood Zone where the structure is not raised 18" above Base Flood Elevation is below:
a. Property Appraisal report (not older than 6 months)
b. Construction cost estimate (labor and material separated)
If you need to be approved for any development in these High-Risk Flood Zones, the substantial improvement (SI) allowed is capped at 50% of the dwelling cost of the structure and proposed improvements.
The method that City of East Palo Alto is using to calculate SI is detailed below:
a. The standard appraisal gives the value of the dwelling, and we require that for calculating the project percentage. Only 50% of that amount is allowed to be improved in the High-Risk Flood Zones.
b. When the project is submitted for development review in High-Risk Flood Zone, we require a construction cost estimate that separates the labor and material. We use the material cost against the overall dwelling cost to make sure it is under 50% SI and award it accordingly.
