''New construction and substantial improvement of any residential structure on Lots 1-20
shall have the lowest floor, including basement, elevated to one foot above the base flood
elevation (449')."
The above-stated note is reflected on the LDAP, PIP, Final Plat and will be included
on any Building Permit plans. BFE = 449; lowest floor/basement = 450'.
Condition 6: Any portion of proposed public rights of way or emergency access ways
within the FEMA flood plain will be elevated as required to maintain an elevation no less
than one foot below the base flood elevation approved by the City Engineer.
All portions of the proposed public rights-of-way or emergency access ways within the
FEMA flood plain have been elevated to an elevation no less than one foot below the
base flood elevation, or 448'. The lowest elevation in the public street = 448.12'.
Condition 7: Prior to LDAP issuance, PIP approval or Final Plat submittal, the Engineer
of Record shall re-calculate the fill necessary to construct proposed improvements and
building pads within the flood plain and provide an analysis which demonstrates the
cumulative effect of proposed fills, when combined with all other existing and anticipated
development, does not increase the water surface elevation of the base flood more than
one foot at any point.
The Engineer of Record has re-calculated the fill necessary to construct proposed
improvements and building pads within the flood plain. Enclosed herewith is an
analysis that demonstrates the cumulative effect of proposed fills, when combined with
all other existing and anticipated development, does not increase the water surface
elevation of the base flood more than one foot at any point. The City Engineer has
accepted these calculations.
I believe this addresses all Of the conditions set forth in the Type II Tentative Subdivision
Review, Staff Report & Decision dated April 7, 2006.
