been affected to the re -submitted (comments in italics; responses in bold). PLEASE NOTE: this letter and
the associated resubmittal addresses revisions from several design professionals under the same cover:
•` INDICATE THE ELEVATION OF THE CENTER LINE OF THE ROAD. ACKNOWLEDGED.
Centerline elevation along Highway A1A has been included in the survey.
• -,1PROPOSED ELEVATION GARAGE IS NOT MATCHING WITH THE BUILDING PLANS. SURVEY
INDICATES 9, BUILDING PLANS INDICATE 9.17'. The elevation listed on the survey describes
the lowest elevation of the garage. The elevation on the Architectural Plans represents the
highest point. The garage floor is sloped.
•�,;. STAIRS IN THE REAR ON THE SURVEYARE NOT MATCHING WITH THE BUILDING PLAN. The
stairs match; the survey simply shows less'lof them. For the purposes of demonstrating their
impact on the ground (footprint), we would say that they are identical.
Mama —PLEASE INDICATE THE OVERHANG FROM FIRST FLOOR ON THE SURVEY AS DASHED LINES.
ACKNOWLEDGED. Survey now delineates the first floor overhang, as directed.
FRONT OF HOUSE ON SURVEY IS NOT MATCHING WITH THE BUILDING PLANS. SEE NORTH
SIDE OF THE FRONT PORCH. ACKNOWLEDGED. Architectural feature at front of proposed
residence has been included in the revised survey.
PLEASE PROVIDE 4 UPDATED SIGNED AND SEALED SURVEYS. (2 FOR HOUSE PERMIT, 2 FOR
FOUNDATION PERMIT). ACKNOWLEDGED.
• PLEASE BE AWARE THAT THE GROUND LEVEL (EXCEPT GARAGE) IS REQUIRED TO MEET
THE FLOOD ZONE AO DEPTH 2' + I'FOR FREEBOARD. THIS MEANS THIS FLOOR IS REQUIRED
TO BE AT 15'. (THE HIGHEST GRADE ELEVATION NEXT TO THE BUILDING (12) + 2' FOR DEPTH
AND V FOR FREEBOARD = 15). ACKNOWLEDGED. Please refer to notes regarding flooding
concerns on sheet A200 of the Architectural Plans. Similar notifications are also included on
the structural plans.
• PLEASE INDICATE AT LEAST ON ONE ELEVATION PAGE THE ACTUAL ELEVATION STARTING
AT GRADE, THAN THE GARAGE LEVEL AND UP UNTIL MEAN HIGH ROOF LINE. THE MEAN HIGH
ROOF LINE CAN'T BE HIGHER THAN 53.41' ACKONOWLEDGED. Architectural sheet A301 has
been revised to demonstrate mean roof height in N.A.V.D.
Please do not hesitate to contact me if you have any questions. We appreciate your considerations and your
