Charlotte Historic District Commission
Staff Review
HDC 2014-193
Application for a Certificate of Appropriateness
Date: October 8, 2014
LOCAL HISTORIC DISTRICT:
Dilworth
PROPERTY ADDRESS:
424-436 E. Park Avenue
SUMMARY OF REQUEST:
Landscape and Site Features - Retaining Wall (Landscape timbers)
OWNER:
D. Patterson Campbell
APPLICANT:
Park Avenue Mews HOA
Details of Proposed Request
Existing Conditions
The existing structure is a contemporary condominium building constructed in 1981, predating the Dilworth
Historic Local District. A new single family home was constructed on the right side. The condo building is
approximately 2-3 feet lower than the adjacent property. The painted brick wall located along the side yard
between the properties is over 6 feet in height.
Proposal
The proposal is the continuation of the brick wall along the side yard and the addition of landscape timbers
acting as a retaining wall toward the front. The proposed height from existing grade is approx. 7-8”.
Policy & Design Guidelines - Landscape and Site Features (page 60)
1. Inspiration for the design of these structures should be drawn from similar historic structures found in the
Local Historic District.
2. Not all landscape structures are appropriate for every lot in the Local Historic District; a retaining wall is not
suitable for a flat lot.
3. Historic precedents indicate appropriate materials such as stone, brick and concrete.
4. Historic site features are considered integral parts of Local Historic District properties, and cannot be removed
without the review of the HDC or its Staff.
5. Walks and walkways in front and side yards or those that are substantially visible from the street should
follow the historic design precedents of their environment.
6. Certain modern materials for landscape and site features are not allowed without the approval of the Historic
District Commission.
• Interlocking concrete block
• Treated landscaping timbers
• Railroad ties
• Pre-fabricated lattice
Policy & Design Guidelines - Fences (page 56)
1. Front yard or front setback fencing is restricted to low picket style fencing. On such fences, the height of the
support posts should not exceed thirty-six inches above grade, and the height of the pickets should not exceed
1
thirty inches. All pickets must be separated by a visible spacing pattern. All front yard fencing on residential
uses must enclose three sides of the front yard. Front yard privacy fences are not allowed.
2. Fencing should not obscure the front elevation of the primary structure on a property. Also, fencing should
not substantially obscure side elevations of the primary structure.
3. Fencing visible from any public street must be judged appropriate to the district. It must have texture
resulting from an interplay of light and dark materials or solids and voids. Solid privacy fences that would be
substantially visible from the street are not allowed.
4. The structural members of any fence must face inward to the property being fenced. The HDC will consider
approving fences where the structural members are an integral part of a overall design, and where both sides
of the proposed fence are identical.
6. No fencing may be over six feet in height, as measured from the outside at grade.
7. Fencing materials and details must be appropriate to the architectural style of the building they enclose.
Proper fencing for a Victorian home can differ substantially from that appropriate to a Craftsman bungalow.
8. Fencing must avoid any style that presents a long unbroken expanse to adjacent properties or to public
throughways.
9. All sides must be appropriately finished.
Staff Analysis
The Commission shall determine if 1) An exception should be granted for the height exceeding 6 feet, and 2) An
exception should be granted for landscape timbers.
