New Flood Maps


Update: Feb. 15, 2019

Enhanced Access to Old Flood Maps

The City has revamped and enhanced the online availability and readability of its series of historic flood maps dating back to the early 1970s.

Accessing these flood maps from the past will become more necessary as the release of new flood maps nears. Early indicators are to expect these new flood maps during late 2019 – early 2020.  These future new maps remain as yet unseen by City staff.

However, it’s anticipated that a number of buildings presently not required to maintain flood insurance – currently located within an “X” type flood zone – may need to obtain flood insurance for the first time, as those “X” zones shrink.

Today’s X-zones weren’t always drawn as they are today. Thus, minimum elevation requirements could have existed in years past, where none are in-place now.

Property owners may need to demonstrate structures built after December 31, 1974 were constructed to the flood zones and elevations existing at the time. Using the City’s GIS web site, the year of construction can be matched-up to the flood map in effect at the time (most recent flood map dated prior to permit for construction).

Video of May 1st, 2018 FEMA Flood Map Update:

This was a two-hour presentation, but the heart of the latest information is mostly from 1:04 to 1:20. If you're not familiar with floodplain transects, you might start at 0:59:30 minutes to gain a little more background information on this topic.

At the end of this program, we moved off-camera to view new Storm Surge Study maps FEMA presented. (Click here to view these maps.)

FEMA Flood Map Update:

FEMA will be holding a public meeting to share results of its storm surge analysis, which is one of the first steps toward the overall flood remapping effort expected to be completed sometime during 2020.
