Enclosure SECTION 24-172. Residential Develo ment Standards ~~~ P (a) Purpose and Intent. It is not the intent of these regulations to restrain individual preferences in residential architecture or design, or to limit or adversely effect individual property rights or property values. The diversity of residential types is recognized as an asset to this community's unique character. Rather, the purpose and intent of these new regulations is, in part, to implement the goals, objectives and polices as set forth within the adopted 2015 Comprehensive Plan, as stated below. Policy A.1.4.3 By December 31, 2005, the City shall consider amendments to its Land Development Regulations, which include provisions intended to retain the unique community identity, the architectural character, and the residential scale of that area of the City known as Old Atlantic Beach. (Atlantic Beach Subdivision "A") Policy A.1.4.4 Within Old Atlantic Beach, the City shall consider options to discourage the redevelopment of residential lots in ways that are inconsistent and incompatible with the historic and existing built environment. The purpose of these regulations is also to regulate the future use and development of land in a manner that minimizes incompatible relationships within neighborhoods that may result from new Development, which because of excessive height, mass, bulk or incongruous design features, may result in development that excessively dominates established development patterns within neighborhoods. (b) Applicability. The Development Standards set forth within this Section shall apply to Development of new Single-family and Two-family Dwellings within that area of the City referred to as Old Atlantic Beach, which for the purposes of this Section shall be bounded by: • 11th Street on the north; • Ahern Street on the south; • Seminole Road on the west, and • the beach on the east. Development, as used within this Section, shall also include total redevelopment of lots and certain renovations and additions to Single-family and Two-family Dwellings as set forth herein. Application of these Development Standards is intended to provide for neighborhood stability and compatibility within the built environment while allowing for continued expansion, redevelopment and new construction within established residential neighborhoods. (c) Permitted Uses. All Uses permitted within the Single-family and Two-family residential Zoning Districts and Uses-by-Exception as may be approved in accordance with Section 24-63, which are regulated by this Section, shall continue to be Permitted Uses or Uses-by-Exception within those Zoning Districts. All new Development of Lots and Parcels shall comply with the residential Density DRAFT 3 Page 1 05/19/2006 DRAFT limitations as set forth within the adopted Comprehensive Plan for the City of Atlantic Beach, as may be amended. (d) Additional Residential Development Standards. The following standards and requirements shall apply to that area defined in preceding paragraph (b), and as further and more specifically described for each particular standard or requirement. (1) Coverage by Buildings. To maintain a sense of openness and to allow for light, air and breezes, the following limits for the amount of a Lot or Parcel, which may be covered by Buildings, shall be as follows: i. On Lots containing 6500 square feet of Lot Area or less: 35% ' ii. On Lots containing more than 6500 square feet of Lot Area: 40% Buildings shall include the Principal Use Building and any permanently placed or constructed Buildings on the Lot. (2) Floor Area Ratio (FAR). Floor Area Ratio limits are established to prevent incompatible mass and scale where new development might otherwise excessively dominate the existing streetscape and existing adjacent residences. FAR shall be defined as the ratio of total counted above-grade floor areas of certain Buildings on a Lot or Parcel compared to the total Lot Area. FAR =Total counted Floor Area =Total Lot Area The following FAR provisions shall apply to new Single-family and Two-family Discuss Dwellings. i. and ii. Are these the i. Lots or Parcels that contain 6000 square feet of Lot Area or less shall be appropriate exempt from Floor Area Ratio limits. numbers? ii. A Floor Area Ratio limit of .54 shall apply to Lots or Parcels that contain more than 6000 square feet of Lot Area. iii. Where the FAR limit applies, FAR calculations shall be included on all plans submitted to the City for review and permitting. iv. The following elements of aSingle-family or Two-family Dwelling shall be counted in the FAR calculation. • Interior heated and cooled areas. • Porches, balconies, patios and breezeways with a solid cover or roof when enclosed by solid walls on more than two sides. • That portion of an attached garage exceeding 400 square feet of Floor Area. DRAFT 3 Page 2 05/19/2006 DRAFT v. The following elements of aSingle-family or Two-family Dwelling shall be excluded from the FAR calculation. • Porches, balconies, patios, breezeways, and decks (as well as overhangs, eaves, cantilevers, awnings and similar features) with a solid cover or roof, but not enclosed by solid walls on more than two sides. Such porches, balconies, patios, breezeways, and decks shall remain open on at least two sides and shall not later be enclosed in any manner. • Detached Private Garages that are incidental to the Principal Use on a Lot. Detached Private Garages shall remain subject to established size, height and placement regulations. ' • Carports that are open on two or more sides. Discuss. • Third-story heated and cooled space, as permitted by following paragraph (6), where such space is constructed within the roof structure of the Dwelling. (3) Front porches. To encourage front porches on Single-family and Two-family Dwellings, an open porch may extend a maximum of 8-feet into the Required Front Yard, subject to the following: ii. Any stairs or steps, exceeding thirty (30) inches in height, shall not further extend into the Required Front Yard. iii. Such porches may have a solid roof, but shall remain open on at least two sides and shall not later be enclosed in any manner. iv. Such open porches, whether covered or not, shall be excluded from the Coverage by Buildings limit as established by preceding paragraph (1). v. Porches, whether covered or not, which are constructed using wood decking or similar materials, which allow water to pass through and under, and which are elevated two or more inches above the ground shall not be considered as Impervious Surface area provided that the ground surface beneath the wood decking is not an Impervious Surface, such as concrete or similar materials which prohibit percolation of stormwater. (4) Side Wall Planes. To avoid stark, exterior side walls from facing the sides of adjacent residences, particularly on two-story and three-story residences, the following standards shall apply to new two-story and three-story Single-family and Two-family Dwellings; to renovations involving Structural Alterations or additions to the sides of existing Single-family and Two-family Dwellings, and where a second or third-story is added to an existing Single-family and Two- family Dwelling. Second and third-story exterior side walls, which exceed 35-feet in length, shall provide horizontal offsets, architectural details, design elements or other features, which serve to break-up the appearance of the side wall, such that adjacent properties are not faced on the side by blank two or three-story walls void of any architectural design other than siding material or windows. DRAFT 3 Page 3 05/19/2006 DRAFT ii. Such design features may also include balconies, bay windows and other types of projecting windows or architectural details provided that these shall not extend more than 24-inches into the Required Side Yard.

Furthermore, an existing Single-family or Two-family Dwelling for that particular Structure, shall not be considered as a Nonconforming Structure such that it may be fully replaceable in its existing footprint and of the same size and architectural design, subject to all applicable building codes and other Land Development Regulations controlling development and redevelopment of such Lots. Any construction that exceeds the existing footprint shall be in compliance with all applicable provisions of this Chapter including minimum Yard Requirements. (ii) Structures damaged, destroyed or demolished or expanded, by any means resulting from the actions of the property owner or authorized agent for a property owner. Single-family or Two-family Dwellings, which are rebuilt or renovated, or expanded by more than twenty-five percent (25%) in Floor Area, shall be subject to applicable provisions of these Residential Development Standards for that portion of the Structure that is rebuilt, renovated or expanded. (~ Annual Review of Residential Development Standards. These regulations shall be reviewed on an annual basis by City staff and the Community Development Board to assess the effectiveness of the regulations in accomplishing the stated Purpose and Intent of this Section. A report shall be presented to the City Commission during a public hearing, which summarizes the applications made during the time from the previous report. If appropriate, revisions shall be made to address needs or deficiencies in accordance with Section 24-61 of these Land Development Regulations. DRAFT 3 Page 5 OS/l9/2006 SUMmARY REVIEW AS FOLLOWS 1.
