Section 6.7.3 - OPD Olde Towne Preservation Overlay District.
A.
Purpose. The purpose of the OPD is to serve the continued preservation and revitalization of the city's historic buildings and neighborhoods in the vicinity of Olde Towne. The OPD permits reduced lot sizes, setbacks, parking, and landscape requirements for properties within commercial or residential districts adjacent to Olde Towne that share development characteristics of Olde Towne. This overlay acknowledges the importance of Olde Towne as the cultural and historic heart of Slidell and as a walkable, mixed-use district where combining residential uses near retail, restaurants, offices, and other small-scale commercial uses are appropriate.
B.
Administration. The Olde Towne Preservation District Commission, as established in section 2-216 of this Code, is responsible for administering the standards unique to the OPD as described in the Official Zoning Map of the City of Slidell.
C.
Relationship to other regulations. The regulations within this section that guide the character and treatment of historic resources, as defined in article 2 of the Slidell UDC, in Olde Towne are intended to complement other regulations in this UDC, including underlying base zoning districts described in the Official Zoning Map of the City of Slidell.
D.
Relationship to historic districts. Where a national historic district designation exists within the boundaries of the Olde Town Preservation Overlay District, the specific character of that historic district shall rule.
E.
Procedures, generally. Refer to article 4, Procedures, of this UDC, section 4.11, Certificate of Appropriateness, for procedures associated with commission review and issuance of a certificate of appropriateness or COA.
F.
Commission COA considerations, or administrative approval of design for review of new construction. Proposals for new construction in the Olde Towne Preservation Overlay District should seek compatibility with existing structures through the appropriate use of site planning, materials, decorative details, architectural elements, and scale. Architectural context is the primary concern, and a proposal does not have to replicate or copy any specific historic style or period. The following factors will be considered:
1.
Scale. Scale is the relationship of the building and its elements (including doors and windows) to other structures in the district. It is important when considering scale, that a careful study be made of the height, width, and mass of buildings in the immediate neighborhood and district as a whole. This study should serve to confirm or deny the appropriateness of the height, width, and mass of the proposed building. Maximum height of any new structure shall conform to the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring & Reconstructing Historic Buildings. In no case shall a new structure exceed a height allowed in the zoning district in which the building is located.
2.
Siting. Siting is the positioning of a building on a lot. This process includes determining the setback of a building, the spacing of this building from adjacent buildings, and the location of walls, fences, walks, drives, parking and landscaping if any of these are used in the overall design. New construction should conform to setback, landscape, and parking requirements of the zoning district in which they are located. Modifications to existing structures and sites can retain their historic setbacks and other siting considerations, as long as they do not conflict with life safety requirements in the International building, residential, and fire codes.
3.
Materials. With the exception of vinyl siding, materials identified in the city's design guidelines for Olde Towne District structures are permitted in the Olde Towne Preservation District. Other materials not specifically mentioned in these design guidelines will be considered on a case-by-case basis and approved by the commission.
4.
Decorative details. Decorative details include ornamentation or embellishment. Ornamentation and embellishment include cornices, lintels, arches, balustrades, chimneys, shutters, columns, and other common details. When used, details should create a unifying effect on a building and should be compatible with the context of the neighborhood.
5.
Architectural elements. Architectural elements includes parts of a building that are integral to its composition. These include balconies, roofs, porches, chimneys, dormers, parapets, and other parts of a building that contribute to its overall shape and silhouette. The choice and arrangement of elements of a proposed building should reflect those of other buildings in the neighborhood. The building should not draw unnecessary attention to itself by failing to relate to neighboring styles. Neither should it copy these styles. The object is to compliment the context of the Olde Towne Preservation District.
G.
Treatment of a historic resource. The U.S. Secretary of Interior has established standards for the treatment of historic properties. Treatments are divided into 4 categories of preservation, rehabilitation, restoration, and reconstruction. The commission shall follow the U.S. Secretary of the Interior's Standards for the treatment of historic properties guidelines for preserving, rehabilitating, restoring and reconstructing historic buildings in considering all proposals for preservation, rehabilitation, restoration, and reconstruction.
1.
Standards for preservation.
a.
A property will be used as it was historically or be given a new use that maximizes the retention of distinctive materials, features, spaces, and spatial relationships. Where a treatment and use have not been identified, a property will be protected, and if necessary, stabilized until additional work may be undertaken.
b.
The historic character of a property will be retained and preserved. The replacement of intact or repairable historic materials or alteration of features, spaces, and spatial relationships that characterize a property will be avoided.
c.
Each property will be recognized as a physical record of its time, place, and use. Work needed to stabilize, consolidate, and conserve existing historic materials and features will be physically and visually compatible, identifiable upon close inspection, and properly documented for future research.
d.
Changes to a property that have acquired historic significance in their own right will be retained and preserved.
e.
Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize a property will be preserved.
f.
The existing condition of historic features will be evaluated to determine the appropriate level of intervention needed. Where the severity of deterioration requires repair or limited replacement of a distinctive feature, the new material will match the old in composition, design, color, and texture.
g.
Chemical or physical treatments, when determined appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used.
h.
Archeological resources will be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken
2.
Standards for rehabilitation.
a.
A property shall be used as it was historically or be given a new use that requires minimal change to its distinctive materials, features, spaces, and spatial relationships.
b.
The historic character of a property shall be retained and preserved. The removal of distinctive materials or alteration of features, spaces, and spatial relationships that characterize a property shall be avoided.
c.
Each property shall be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding contextual features or elements from other historic properties, shall not be undertaken.
d.
Changes to a property that have acquired historic significance in their own right shall be retained and preserved.
e.
Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize a property shall be preserved.
f.
Deteriorated historic features will be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. Replacement of missing features shall be substantiated by documentary and physical evidence.
g.
Chemical or physical treatments, if appropriate, shall be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used.
h.
Archeological resources will be protected and preserved in place. If such resources must be disturbed, mitigation measures shall be undertaken.
i.
New additions, exterior alterations, or related new construction will not destroy historic materials, features, and spatial relationships that characterize the property. The new work will be differentiated from the old and shall be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment.
j.
New additions and adjacent or related new construction shall be undertaken in such a manner that, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired.
3.
Standards for restoration.
a.
A property shall be used as it was historically or be given a new use which reflects the property's restoration period.
b.
Materials and features from the restoration period shall be retained and preserved. The removal of materials or alteration of features, spaces, and spatial relationships that characterize the period shall not be undertaken.
c.
Each property will be recognized as a physical record of its time, place, and use. Work needed to stabilize, consolidate and conserve materials and features from the restoration period shall be physically and visually compatible, identifiable upon close inspection, and properly documented for future research.
d.
Materials, features, spaces, and finishes that characterize other historical periods shall be documented prior to their alteration or removal.
e.
Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize the restoration period shall be preserved.
f.
Deteriorated features from the restoration period shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and, where possible, materials.
g.
Replacement of missing features from the restoration period shall be substantiated by documentary and physical evidence. A false sense of history shall not be created by adding contextual features, features from other properties, or by combining features that never existed together historically.
h.
Chemical or physical treatments, if appropriate, shall be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used.
i.
Archeological resources affected by a project shall be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken.
j.
Designs that were never executed historically shall not be constructed.
4.
Standards for reconstruction.
a.
Reconstruction shall be used to depict vanished or non-surviving portions of a property when documentary and physical evidence is available to permit accurate reconstruction with minimal conjecture and such reconstruction is essential to the public understanding of the property.
b.
Reconstruction of a landscape, building, structure, or object in its historic location shall be preceded by a thorough archeological investigation to identify and evaluate those features and artifacts which are essential to an accurate reconstruction. If such resources must be disturbed, mitigation measures shall be undertaken.
c.
Reconstruction shall include measures to preserve any remaining historic materials, features, and spatial relationships.
d.
Reconstruction shall be based on the accurate duplication of historic features and elements substantiated by documentary or physical evidence rather than on conjectural designs or the availability of different features from other historic properties. A reconstructed property shall recreate the appearance of the non-surviving historic property in materials, design, color, and texture.
e.
A reconstruction shall be clearly identified as a contemporary re-creation.
f.
Designs that were never executed historically shall not be constructed. When a contemporary depiction is required to understand and interpret a property's historic value (including the recreation of missing components in a historic district or site); when no other property with the same associative value has survived; and when sufficient historical documentation exists to ensure an accurate reproduction, reconstruction may be considered as a treatment.
H.
Standards for additional design elements.
1.
Fences. Fence design must be in harmony with the nature of the district and be provided in compliance with applicable provisions of this UDC for fences. The following fencing materials are not acceptable: barbed wire; chain-link, except in the side and rear yard; concrete block unless clad in stucco or another approved material; stockade; plywood; Hardi board; or asbestos board.

The permit for all such new construction or any renovation shall be subject to the requirements of this division.
a.
Encroachment into public right-of-way. If an existing balcony, canopy, or awning is proposed to be extended or substantially improved or a new balcony, canopy, or awning is proposed to be added and the improvement encroaches into the public right-of-way, permission from the city in the form of an encroachment agreement shall be required before a COA may be issued.
b.
Encroachment into the setback. If an existing balcony, canopy, or awning is proposed to be extended or substantially improved or a new balcony is proposed to be added and the improvement encroaches into either the front, rear, or side yard setback area, a variance from the city's board of adjustments shall be required before a COA may be issued.
3.
Signs.
a.
Signs must meet all applicable requirements of this Code.
b.
Signs must also conform to character of the surrounding area. In addition to meeting the requirements of article 8 of this UDC, approval of the display of a sign in the Olde Towne Preservation Overlay District shall be granted by the commission only when such signs relate to the appearance, color, size, position, method of attachment, texture of materials and design, and conform to the distinctive character of the Olde Towne Preservation Overlay District or do not injuriously affect it or impair the value to the community of those buildings having architectural or historical worth.
c.
No signs to be displayed in certain places. No sign shall be displayed above the peak of the roof of any buildings in the Olde Towne Preservation Overlay District, unless approved by the commission.

6.
Demolition. In order maintain the historic character of the district, demolition of historic structures must be reviewed by the commission before a permit is approved. The purpose of the review is to consider the impact the impact demolition of the structure may have on the city's preservation district's designation, to recommend alternatives to demolition, and to recommend salvage of historic materials for reuse in other preservation projects. Demolition can be either at the request of the property owner or an action by the city to remove a deteriorated structure that poses a threat to health and safety.
a.
Demolition by request of the owner. When a property owner applies for a permit to demolish a historic structure, the application will be referred to the commission for review at the next scheduled meeting of the commission. Before a permit can be issued, the commission must review the application to determine if loss of this structure will adversely impact the city's certified local government or National Register designation. As part of its review the commission will consider alternatives to demolition and opportunities to salvage historic materials for reuse with the owner. The commission will make a recommendation to the owner based on their review. If after receiving the commission's recommendation the owner decides to proceed with the demolition the department of planning will sign off on the permit, provided all other requirements have been met.
b.
Demolition by neglect. Before the city council decides to demolish a historic structure, it must first be referred to the commission for review and recommendation. The commission will determine if loss of this structure will adversely impact the city's certified local government or National Register designation. As part of its review the commission will consider alternatives to demolition and opportunities to salvage historic materials for reuse. The commission's recommendation will be forwarded to the city council for their consideration when deciding whether or not to proceed with the demolition.

D.
Airport hazard height limitations. Specific height limitations are in effect within the AOD, applicable based on the existence of any official airport within the City of Slidell, including the airport's flight approach areas, horizontal areas, and conical areas as defined and regulated in this section. Where an area is covered by more than one height limitation, the more restrictive limitation shall prevail.
1.
Airport height areas.
a.
Instrument approach area. At such time as an instrument approach is installed at an airport in the parish the instrument approach area shall extend from each end of the instrument runway at a distance of 200 feet, with a width of 1,000 feet. It shall widen uniformly thereafter for a distance of 50,200 feet with an ultimate width of 16,000 feet. Its centerline shall be the continuation of the centerline of the runway. There were no runways in the parish with instrument approaches in 1965.
b.
Noninstrument approach area. A noninstrument approach area is established at each end of all noninstrument runways for noninstrument landings and takeoffs. The noninstrument runway shall have a width of 250 feet at a distance of 200 feet beyond each end of the runway widening thereafter uniformly to a width of 2,250 feet at a distance of 10,200 feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway.
c.
Transition area. Transition areas are hereby established adjacent to each instrument and noninstrument runway and approach area. Transition areas symmetrically located on either side of runways have variable widths. Transition areas extend outward from a line 200 feet on either side of the centerline of the noninstrument runway for the length of such runway plus 200 feet on each end and 500 feet on either side of the centerline of the instrument runway, for the length of such runway plus 200 feet at each end and are parallel and level with such runway centerlines. The transition areas along such runways slope upward and outward one foot vertically for each seven feet horizontally to the point where they intersect the surface of the horizontal area. Further, transition areas are established adjacent to both instrument and noninstrument approach areas for the entire length of the approach areas. These transition areas have variable widths. Such transition areas flare symmetrically with either side of the runway approach areas from the base of such areas and slope upward and outward at the rate of one foot vertically for each seven feet horizontally to the points where they intersect the surfaces of the horizontal and conical areas. Additionally, transition areas are established adjacent to the instrument approach area where it projects through and beyond the limits of the conical areas, extending a distance of 5,000 feet, measured horizontally from the edge of the instrument approach areas at right angles to the continuation of the centerline of the runway.
d.
Horizontal area. A horizontal area is hereby established as the area within a circle with its center at the airport reference point and having a radius of 5,000 feet. The horizontal area does not include the instrument and noninstrument approach areas and the transition areas.
e.
Conical area. A conical area is hereby established as the area that commences at the periphery of the horizontal area and extends outward therefrom a distance of 3,000 feet. The conical area does not include the instrument approach areas.
2.
Height limitations. Nothing in this section shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height up to 45 feet above the surface of the land. Except as otherwise provided in this Code, no structure or tree shall be erected, altered, allowed to grow, or maintained in any area created by this section to a height limit herein established for such area. Such height limit actions are hereby established for each of the areas in question as follows:
a.
Instrument approach area. One foot in height for each 50 feet in horizontal distance beginning at a point 200 feet from and at the elevation of the end of the instrument runway and extending to a distance of 10,200 feet from the end of the runway; thence one foot in height for each 40 feet in horizontal distance to a point 50,200 feet from the end of the runway.
b.
Noninstrument approachareas. One foot in height for each 20 feet in horizontal distance beginning at a point 200 feet from and at the elevation of the end of the noninstrument runway and extending to a point 10,200 feet from the end of the runway.
c.
Transition areas. One foot in height for each seven feet in horizontal distance beginning at any point 250 feet normal to and at the elevation of the centerline of noninstrument runways extending 200 feet beyond each end thereof and 500 feet normal to and at the elevation of the centerline of the instrument runway, extending 200 feet beyond each end thereof, extending to a height of 150 feet above airport elevation. In addition to the foregoing, there are established height limits of one-foot vertical height for each seven feet horizontal distance measured from the edges of all approach areas zones for the entire length of the approach areas and extending upward and outward to the points where they intersect the horizontal or conical surfaces. Further, where the instrument approach area projects through and beyond the conical area, a height limit of one foot for each seven feet of horizontal distance shall be maintained beginning at the edge of the instrument approach area and extending a distance of 5,000 feet from the edge of the instrument approach area measured normal to the centerline of the runway extended.
d.
Horizontal zone. 150 feet above the airport elevation or a height of 168 feet above mean sea level.
e.
Conical zone. One foot in height for each 20 feet of horizontal distance beginning at the periphery of the horizontal area, extending to a height of 273 feet mean sea level above the Slidell Airport elevation.
E.
Marking and lighting. The owner of any nonconforming structure or tree is hereby required to permit the installation, operation and maintenance thereon of such markers and lights as shall be deemed necessary by the airport authority to indicate to the operators of aircraft in the vicinity of the airport, the presence of such airport hazards.
