Other: New primary structure
New primary structure fronting Washington Avenue. The one-story single-family house with a basement-level internal accessory dwelling unit (ADU) will measure 42'-6" wide by 74'-2" deep, and the main massing is proposed to be set 31'-3" from the front lot line (porch at 20'-1").

The house features a front-gable roof clad with dimensional asphalt shingles, and the roofline features trim, faux rafter tails, and eave overhangs. The fields are clad in shake siding, and with decorative brackets on the front and side gable fields. The façade features a full-length, 11' deep front-porch recessed under the primary roofline and supported by two square brick piers. The porch will feature a 36" tall wood handrail with simple square balusters. The front porch steps and flooring will be unstained concrete, and the porch ceiling material is not specified. The house will be clad in wood clapboard siding with wood trim and corner boards, and the foundation will be clad in brick.

The façade (north) features three bays with paired 3/1 double-hung windows in the left bay, a wood paneled door (half-lite or quarter-lite) in the central bay, and tripled 3/1 double-hung windows in the right bay; the front-gable field features paired 3-light casement windows. The left elevation features a side-gable roof massing with a basement level, with two pairs and three 3/1 double-hung windows on the primary story, and a fiberglass secondary entrance to the backyard; the basement level features two 3/1 double-hung windows, the fiberglass primary entrance to the ADU, and the wooden quarter-lite garage doors that mimic carriage doors. The primary story of the right elevation (west, facing Polk St.) features a gable-roof massing, two 3-pane casement windows, a pair of 3/1 double-hung windows, four grouped 3/1 double-hung windows, and a single 3/1 single-hung window; the basement level features three 3/1 double-hung windows. The rear elevation features a half-length back porch (depth unspecified) with a concrete floor recessed under the primary roofline and supported by one brick column identical to those on the façade, along with tripled 3/1 double-hung windows and two 3-pane casement windows. All windows will be made of aluminum-clad wood with operable sashes and simulated divided lites, and all windows and doors feature wood trim.

CONDITIONS OF APPROVAL PER 4/17/2025 HZC: 1) final construction drawings indicating all dimensional details be sent to staff for approval; 2) final siding, window, masonry, and door selections be sent to staff for approval; 3) meeting all applicable requirements of the City Zoning Ordinance and City Engineering standards.

Staff Comments
N/A
    Vacant lot.

Roofs:
1. Make the shape and pitch of roofs on new construction imitate the shape and pitch of roofs on neighboring existing houses or other houses of the same architectural style. Replacement roofs must copy the shape and pitch of original roofs, and the soffit, fascia and trim detail between roof and wall should mimic the original.
2. The eaves on additions or new buildings shall have an overhang that mimics the original eaves. A minimum overhang of at least eight inches should be used on new buildings or additions to existing buildings.
3. Repair or replace roof details ( chimneys, roof cresting, finials, attic vent windows, molding and other unique roof features). Use some of these details in designing new buildings.
4. Materials used in roofing existing buildings or new construction shall duplicate the original roofing materials as much as possible. Asphalt or fiberglass shingles can be appropriate, as are slate, standing seam metal, or metal or wood shingle roof coverings. The color of roofing materials should be a dark green, charcoal gray or black or dark reddish brown, to simulate the original roof colors.

Porches:
3. New buildings constructed in Edgewood - Park City must contain front porches large enough to provide seating. The proportion of the porches to the front facades is to be consistent with the historic porches in the neighborhood. Details such as columns, posts, piers, balustrades and porch flooring and ceilings will be built with materials that are consistent in appearance with historic materials.
Entrances:
6. Secondary entrances shall be compatible with the originals in size, scale and materials.

Wall Coverings--Wood:
3. New construction shall use materials that duplicate the appearance of neighboring historic buildings, so that the new buildings blend with the fabric of the area. This includes the use of corner and trim boards and appropriate door and window trim. If artificial siding is used on new construction, it must be vented every twelve inches, and must look like 4" lap siding unless a different pattern is approved by the historic zoning commission.

Infill Buildings:
1. Maintain the historic facade lines of streetscapes by locating the front walls of new buildings in the same plane as the facades of adjacent buildings. Never violate the existing setback pattern by placing new buildings in front of or behind the historic setback line. Avoid placing buildings at odd angles to the street.
2. Relate the size and proportions of new structures to the scale of adjacent buildings.
3. Break up boxlike forms into smaller masses like those of buildings from the historic period. New buildings should be designed with a mix of wall areas with door and window elements in the facade like those found on nearby historic houses. The placement of door and window openings should be imitated.
4. Relate the vertical, horizontal or non-directional facade character of new buildings to the directional alignment of nearby buildings. A new building should reinforce the horizontal and vertical connection between historic houses present on the street.
5. Relate the roof forms of the new buildings to those found in the area, duplicating existing roof shapes and pitches.
6. New buildings should equal the average height of existing adjacent buildings.
7. New housing shall be built with raised foundations or designed to suggest that there is a raised foundation equal to those of adjacent buildings.
8. In new buildings, the height of roofs and eaves shall conform to adjacent properties. Height of stories, windows and doors must mimic adjacent historic buildings.
9. The materials used for new buildings will be consistent in appearance with existing historic building materials along the street.
10. Front elevations must be designed with a strong sense of entry.
11. Do not reproduce the styles, motifs or details of historic older architecture.


New Guidelines
Construction of Primary Buildings:

1. Design new buildings to be compatible with the existing site.
a. Significantly altering the existing topography of a site to accommodate a new structure is not appropriate.
b. Consolidating lots in to a larger property in order to accommodate a larger structure disrupts the pattern of properties within the district and is not appropriate.

2. Locate new buildings in a manner that is compatible with established precedents of building patterns within the district.
a. Retain the historic relationship among buildings within the district by basing the location of a new building on patterns of existing setbacks, orientation, and spacing between buildings.
b. Maintain the existing spacing of front and side yard setbacks along a block.
c. Orient the front entrance toward the main street.
d. Site a building so that it is parallel to existing lot lines.
e. Design new porches to be consistent with the rhythm of those existing in the district.
f. Locate related new accessory buildings at the rear of the lot consistent with those existing in the surrounding district.

3. Design new buildings so their size is compatible with existing buildings in the district.
a. Maintain the established height and scale of the street by designing new buildings to be within the typical range of heights and forms.
b. Design new buildings to have massing similar to those traditionally found within the district.
c. Use floor-to-ceiling heights that are consistent with those of existing structures within the district.
d. Choose a building form that has a similar complexity to those elsewhere in the surrounding area.
e. Break up large massing through vertical and horizontal articulation.

4. Design new buildings with features that reflect those existing in the district.
a. Include substantial front porches that are at least 8 feet in depth.
b. Balance façade proportions with those historically found in the district. The composition and scale of façade elements, such as porches, significantly affect the aesthetic of the district.
c. Use materials with traditional dimensions.
d. Maintain traditional ratios of solid wall spaces to openings.

5. Utilize window and door openings that are compatible with those on surrounding buildings in placement, spacing, scale, proportion, and size. Windows are to have a vertical orientation.

6. Select a roof form and pitch that is compatible with established precedents within the district.
a. Use roof forms similar to those traditionally present in the streetscape and the district, relating roof pitch and shape to the scale of the building.
b. Use contemporary interpretations of traditional features such as cornices and rake boards to add visual interest.

7. Design a new building to be compatible in character with existing structures but also to be a product of its own time.
a. It is appropriate to employ contemporary interpretations of historic designs or use a simple contemporary design that conforms to general characteristics such as massing, scale, and proportions.
b. Include architectural details or building articulation such as cornices, lintels, brackets, and chimneys. Contemporary interpretations of traditional details are encouraged, but avoid oversimplified, bland buildings that stand in stark contrast to the rich architectural variety within the district.

8. Utilize traditional materials or alternative materials that are comparable to those found on nearby buildings within the district.
a. Select materials with textures and finishes that are compatible with those of the surrounding area, promote a sense of human scale, and have proven durability.
b. Where wood siding is installed, utilize trim boards, which show depth and have a more finished appearance.
c. Use masonry materials that are compatible with the character of traditional masonry materials in size and texture.
d. Alternative materials to wood are appropriate for new construction. Materials that simulate wood siding may be appropriate for new buildings, excluding vinyl and aluminum siding.
e. Where fiber cement board or other wood alternative materials are selected, use a smooth- finish and maintain a 4-inch reveal compatible with historic details.
f. It is not appropriate to use fiber cement board or other material that has a faux wood grain. buildings that stand in stark contrast to the rich architectural variety within the district.

9. New parking pads, driveways, and access points for new construction and existing houses should be unobtrusive to the existing patterns of the block and streetscape.
a. Do not locate parking pads in front yards.
b. New curb cuts can result in removing historic sidewalk, curb details, or retaining walls and should be kept to a minimum.
c. When possible, alley access should be used for new garages or parking areas on blocks with operable alleys.
d. On streets without alleys, parking areas should be at least twenty feet behind the front façade of the house, with access limited to one lane between the street and the façade.
