The purpose of the Historic Residential Low-Density (HRL) District is to: 

1. reduce density that is accessible only by substandard Streets so these Streets are not impacted beyond their reasonable carrying capacity,
   
2. provide an Area of lower density Residential Use within the old portion of Park City,
   
3. preserve the character of Historic residential Development in Park City,
   
4. encourage the preservation of Historic Buildings and/or Structures,
   
5. encourage construction of Historically Compatible Structures that contribute to the character and scale of the Historic District, and maintain existing residential neighborhoods.
   
6. establish Development review criteria for new Development on Steep Slopes which mitigate impacts to mass and scale and the environment, and
   
7. define Development parameters that are consistent with the General Plan policies for the Historic core.

      8. Landscaping.
         
   2. Exceptions to the Building Pad Area, excluding Bay Windows, are not included in the Building Footprint calculations, and are subject to Planning Department approval based on a determination that the proposed exceptions result in a design that:
      
      1. provides increased architectural interest consistent with the Design Guidelines for Historic Districts and Historic Sites;
         
      2. maintains the intent of this section to provide horizontal and vertical Building articulation.
         
5. BUILDING FOOTPRINT (HRL DISTRICT). The maximum Building Footprint of any Structure shall be located on a Lot, or combination of Lots, not exceeding 18,750 square feet in Lot Area, shall be calculated according to the following formula for Building Footprint. The maximum Building Footprint for any Structure located on a Lot or combination of Lots, exceeding 18,750 square feet in Lot Area, shall be 4,500 square feet; with an exemption allowance of 400 square feet per dwelling unit for garage floor area.  A Conditional Use Permit is required for all Structures with a proposed footprint of greater than 3,500 square feet.
   
   Accessory Buildings listed on the Park City Historic Sites Inventory that are not expanded, enlarged or incorporated into the Main Building, shall not count in the total Building Footprint of the Lot.
   
   MAXIMUM FP = (A/2) x 0.9^A/1875
   
   Where FP = maximum Building Footprint and A = Lot Area.  
   
   Example:  3,750 sq. ft. Lot: (3,750/2) x 0.9^(3750/1875) = 1,875 x 0.81 = 1,519 sq. ft.

      2. The proposed option is the only feasible option for the elevator on the Site.
         
      3. The proposed elevator and floor plans comply with the American Disability Act (ADA) standards. 
   4. GARAGE ON DOWNHILL LOT. The Planning Commission may allow additional Building Height (see entire Section 15-2.1-5) on a downhill Lot to accommodate a single car wide garage in a Tandem Parking configuration; to accommodate circulation, such as stairs and/or an ADA elevator; and to accommodate a reasonably sized front entry area and front porch that provide a Compatible streetscape design. The depth of the garage may not exceed the minimum depth for internal Parking Space(s) as dimensioned within this Code, Chapter 15-3. The additional Building Height may not exceed thirty-five feet (35’) from Existing Grade.

Development on Steep Slopes must be environmentally sensitive to hillside Areas, carefully planned to mitigate adverse effects on neighboring land and Improvements, and consistent with the Design Regulations for Historic Districts and Historic Sites Chapter 15-13 and Architectural Review Chapter 15-5. 

For the purpose of measuring Slope, the measurement shall include a minimum horizontal distance of fifteen feet (15') measured perpendicular to the contour lines on the certified topographic survey. The measurement shall quantify the steepest Slope within the Building Footprint and any Access driveway.

1. Steep Slope Determination. 
   
   1. A Steep Slope Conditional Use permit is required for construction of any Structure with a Building Footprint in excess of two hundred square feet (200 sq. ft.) if said Building Footprint is located on or projecting over an existing Slope of thirty percent (30%) or greater.
      
   2. A Steep Slope Conditional Use permit is required for construction of any addition to an existing Structure, when the Building Footprint of the addition is in excess of two hundred square feet (200 sq. ft.), if the Building Footprint of the addition is located on or projecting over an existing Slope of thirty percent (30%) or greater.
      
   3. A Steep Slope Conditional Use permit is required for any Access driveway located on or projecting over an existing Slope of (30%) or greater.
   4. Any disturbance that creates a change from Existing Grade or elevation greater than four feet, cuts into the Steep Slope, or requires retaining walls to construct the Structure (including patio, hot tub, pool, landscaping/grading).
2. Steep Slope Review. To fully evaluate the Criteria below, the Applicant shall provide the following information:
   1. GEOTECHNICAL ANALYSIS. For Structures that create a change from Existing Grade or elevation greater than four feet, cut into the Steep Slope, or require retaining walls to construct the Structure, a geotechnical report is required. The Applicant shall provide the Planning Department with a geotechnical report prepared by a licensed geotechnical engineer, engineering geologist, or other qualified professional. The report must include information such as soils characteristics and preliminary structural recommendations intended to inform the design and mitigation of soils conditions, slope limitations, and/or ground water. The Engineering or Building Department may request additional information in the form of a geotechnical survey if additional information is deemed necessary.
   2. SLOPE/TOPOGRAPHIC MAP. Certified boundary survey depicting contours at an interval of two feet (2’) or less that identifies Very Steep Slopes (40% or greater) within fifty feet (50’) of the Property boundary and highlights areas of high geologic hazard, areas subject to land sliding, and all Steep Slopes for areas with a rise of at least twenty-five feet (25’) vertically and a run of at least fifty feet (50’) horizontally in the following categories:
      1. Greater than fifteen percent (15%), but less than or equal to thirty percent (30%) (shown in yellow)
      2. Greater than thirty percent (30%) but less than or equal to forty percent (40%) (shown in orange)
      3. Very Steep Slopes, greater than forty percent (40%) (shown in red)
         
3. Conditional Use Permit Criteria.
   The Planning Commission may review Steep Slope Conditional Use permit Applications as Consent Calendar items. Steep Slope Conditional Use permit Applications shall be subject to the following criteria:
   1. LOCATION OF DEVELOPMENT. Development is located and designed to reduce visual and environmental impacts of the Structure.
      
   2. VISUAL ANALYSIS. To determine potential impacts of the proposed Access, and Building mass and design and to identify the potential for Screening, Slope stabilization, erosion mitigation, vegetation protection, and other design opportunities, a visual analysis of the project from key Vantage Points is required. The Applicant must provide the Planning Department with:
      1. Four panoramic views of existing property showing the site from the perimeter of the property from 90-degree compass intervals (camera facing toward site). Four panoramic views showing the neighborhood taken from the perimeter of the property at 90-degree compass intervals (camera facing away from site). One aerial photograph placing the subject in a neighborhood context.
      2. Streetscape elevation – including 100 feet on either side of the property along the project side of the street to indicate accurate height, width, and building or all proposed work in relation to existing surrounding and adjacent buildings, drawn at minimum 1/8 inch scale. If access to properties is limited, a photographic streetscape is allowed.
      3. A 3D massing model illustrating the proposed project from designated Vantage Points (see Planning Staff to review and establish Vantage Points for the Application).
      4. A rendering that superimposes the proposed project on a photo of the site and streetscape.
   3. ACCESS. Access points and driveways must be designed to minimize Grading of the natural topography and to reduce overall Building scale. Shared Driveways and Parking Areas, and side Access to garages are strongly encouraged, where feasible.
   4. TERRACING. The proposed plans shall include detailed information, including height from Existing Grade, width, and length of all proposed retaining walls. The Applicant shall terrace retaining walls to return to Natural Grade. A Building Permit, including drawings stamped by a licensed engineer, is required for any retaining wall or combination retaining wall with a total or combined height greater than four feet (4’) in height. A combination retaining wall is defined as any series of retaining walls in which the horizontal separation between subsequent walls is closer than 1.5:1 compared to the height of the individual walls. If the height of any retaining walls is proposed to be modified by more than twelve inches in height, width, length, or location, the Applicant shall file a modification application with the Planning Department and return to the Planning Commission for review and Final Action. Additionally, modifications of pervious material to impervious material or changes to excavation depths require a modification application and Planning Commission review and Final Action.
   5. BUILDING LOCATION. Buildings, Access, and infrastructure must be located to minimize cut and fill that would alter the perceived natural topography of the Site. The Site design and Building Footprint must coordinate with adjacent Properties to maximize opportunities for open Areas and preservation of natural vegetation, to minimize driveway and Parking Areas, and to provide variation of the Front Yard. 
   6. BUILDING FORM AND SCALE. Where Building masses orient against the Lot’s existing contours, the Structures must be stepped with the Grade and broken into a series of individual smaller components that are Compatible with the District. Low profile Buildings that orient with existing contours are strongly encouraged. The garage must be subordinate in design to the main Building. In order to decrease the perceived bulk of the Main Building, the Planning Commission may require a garage separate from the main Structure or no garage.
   7. SETBACKS. The Planning Commission may require an increase in one or more Setbacks to minimize the creation of a “wall effect” along the Street front and/or the Rear Lot Line. The Setback variation will be a function of the Site constraints, proposed Building scale, and Setbacks on adjacent Structures. 
   8. DWELLING VOLUME. The maximum volume of any Structure is a function of the Lot size, Building Height, Setbacks, and provisions set forth in this Chapter. The Planning Commission may further limit the volume of a proposed Structure to minimize its visual mass and/or to mitigate differences in scale between a proposed Structure and existing Structures. 
   9. BUILDING HEIGHT (STEEP SLOPE). The Zone Height in the HRL District is twenty-seven feet (27') and is restricted as stated above in Section 15-2.1-5. The Planning Commission may require a reduction in Building Height for all, or portions, of a proposed Structure to minimize its visual mass and/or to mitigate differences in scale between a proposed Structure and the Historic character of the neighborhood's existing residential Structures.

1. Tandem Parking is allowed in the Historic District.
   
2. One (1) Shared Driveway is allowed along shared Side or Rear Lot Lines to provide Access to Parking in the rear of the Main Building or below Grade if both Properties are deed restricted to allow for the perpetual Use of the shared drive.
   
3. Common Parking Structures are allowed as a Conditional Use where it facilitates: 
   
   1. the Development of individual Buildings that more closely conform to the scale of Historic Buildings and/or Structures in the District; and/or 
      
   2. the reduction, mitigation or elimination of garage doors at the Street edge. 
      
4. A common Parking Structure may occupy below Grade Side Yards between participating Developments if the Structure maintains all Setbacks above Grade. Common Parking Structures requiring a Conditional Use Permit are subject to a Conditional Use review, Section 15-1-10.
   
5. Driveways between Structures are allowed in order to eliminate garage doors facing the Street, to remove cars from on-Street parking, and to reduce paved Areas, provided the driveway leads to an approved garage or approved Parking Area.
