Re: Zoning Confirmation for 71 Coral Street (RE# 169596-0000)
within the City of Atlantic Beach
Dear Ms. Johnston:
The above referenced property is located within the Residential General, Two-family (RG) Zoning
District. Single-family residential use, and Two-family residential use subject to sufficient lot size are
Permitted Uses within this Zoning District.
The lot is within the Residential, Low Density (RL) land use designation, which requires a minimum
of 14,500 square feet of lot area for a new Two-family Dwelling. The lot appears to be 50' wide by
110" feet deep. As such the lot is not of sufficient size for a new Two-family dwelling. Development
of a Single-family Dwelling is permitted subject to customary and applicable zoning and building
regulations.
There are no pending code enforcement actions at this property, and no code violations to the City's
knowledge.
I have enclosed a copy of Section 24-107 from the City's Land Development Regulations, which
contains the RG provisions. I have also included Section 24-66, the City's stormwater regulations,
which would apply to development of this lot. Please feel free to contact me with any questions.
Sincerely,
Sonya Doerr, AICP
Planning Director

Initial Effective Date: January 01. 2002 ♦ Last amended: March 08, 2010 by Ordinance 90-10-212 43
Sec. 24-66. Stormwater, Drainage, Storage and Treatment Requirements.
(a) Topography and Grading. All Lots and Development sites shall be constructed and graded in such a
manner so that the stormwater drains to the adjacent Street, an existing natural element used to convey
stormwater (See section 22-303, definitions: Stormwater Management System), or a City drainage structure
after meeting on-site storage requirements, as set forth within this Section. The City shall be provided with
a pre -construction topographical survey prior to the issuance of a Development Permit and a post -
construction topographical survey prior to the issuance of a Certificate of Occupancy. Elevations in all
topographic surveys will be referenced to NAVD 1988. Said surveys shall be prepared by a licensed
Florida surveyor, and the requirement for either or both surveys may be waived by the Director of Public
Works if determined to be unnecessary.
Except as required to meet Coastal Construction Codes as set forth within a valid permit from the Florida
Department of Environmental Protection; or as required to meet applicable flood zone or stormwater
regulations as set forth herein, the elevation or topography of a Development or Redevelopment Site shall
not be altered.
(b) On -Site Storage. The Applicant shall be required to provide on-site storage, such that there is no increase
in the rate or volume of flow to off-site, from every developed or redeveloped Parcel, and for any addition or
modification that increases the impervious surface area on a developed lot by 10% or 400 SF, whichever is
smaller and provide documentations and calculations to demonstrate compliance. Development Projects
previously permitted by the St. Johns River Water Management District (SJRWMD), which have an in-
compliance retention or detention system that collects and controls run-off, are exempt, however a copy of the
Engineer's Certification of As -Built Construction to the SJRWMD must be submitted to the City before issuing
building permits for individual lot construction may begin. The requirement for on-site storage may be waived
by the Director of Public Works if storage is determined to be unnecessary or unattainable. If on-site storage is
required, an As -Built survey, signed and sealed by a licensed Florida surveyor, documenting proper
construction and required volume of the storage system, must be submitted to the Director of Public Works
prior to permit closeout or issuance of a Certificate of Occupancy. For an under -ground system, a notarized
letter from the General Contractor, along with red -lined plans and construction photographs, will be sufficient
to document proper construction.
Volume calculations for Lots that require on-site storage should be based on the difference in run-off
volume generated by the new impervious area ("delta volume") and would be calculated by:
V=CAR/12, where
V = volume of storage in cubic feet,
A = area of the lot in square feet,
R = 25 year and 24 hour rainfall depth (9.3 inches) over the lot area, and
C = run-off coefficient, which is 0.6 for the 50% maximum imperviousness, 0.4 for 25%
imperviousness, and 0.2 for 0% imperviousness.
This delta volume (post V minus pre -V in cubic feet) must be stored at least 1 foot above the wet season
water table and below the overflow point to off-site (in many cases this may be the adjacent road elevation).
As an option, and as approved by the Director of Public Works, the owner of the parcel to be developed or
redeveloped may implement, at the applicant's cost, off-site storage and necessary conveyance to control
existing flood stages off-site.
(c) Flood Plain Storage. There shall be no net loss of storage for areas in the 100 -year floodplain, where a
floodplain elevation has been defined by either the Federal Emergency Management Agency (FEMA) on
Flood Insurance Rate Maps (FIRMS), the 1995 Stormwater Master Plan, the Core City project, or the 2002
Stormwater Master Plan Update (e.g., Hopkins Creek). Site grading shall create storage on-site to mitigate
for filling of volume on-site. This storage is in addition to the storage required for the increase in
Impervious Surface Area. The Applicant shall provide signed and sealed engineering plans and calculations
documenting that this `no net loss' requirement is met.
Initial Effective Date: January 01, 2002 ♦ Last amended: March 08, 2010 by Ordinance 90-10-212 28
