Re: Bethel Road Estates
Final Plat
Dear Mr. Martin:
The purpose of this letter is to clarify the minimum finish floor elevations of the lots within this
platting. JD Landes is currently finalizing a flood study of this area in an effort to obtain a
Conditional Letter of Map Revision in order to place fill within the limits of lot 2 of this plat. No
fill is being placed within the floodplain limits oflotl. We hope to submit this flood study to you
for review next week.
We understand that this CLOMR has not been approved and therefore cannot be utilized in the
platting of this property at this time. We have established these minimum finish floor elevations
for platting at this time:
Lot 1 Block 1 498.7
Lot 2 Block 1 498.7
The existing 100-year water surface elevation shown on the Flood Rate Insurance Map for these
lots is.approximately 494.5. Adding 2 feet to this water surface in accordance with the City's
floodplain ordinance, results in 496.5.
The 100-year fully develOped water surface elevation for these lots is 497.7, as determined from
the 1990 Albert Halff study prepared for the City. Adding 1 foot to this water surface elevation
equals 498.7 in accordance with the City's floodplain ordinance. This elevation is greater than
the elevation resulting from the FIRM and therefore controls. We will adjust our site plan grades
up slightly to reflect these minimums.
Please contact us as soon as possible upon review of this information, so that we can proceed
with the plat filing, or supply you with additional data.
Sincerely,
,(/J/iastin D. Landes, P.E.
