In addition to any other provisions of this chapter the following standards for arrangement and development of lands and buildings are required in the Single Family Planned Residential District.
(a) Intensity of Use. The maximum density shall be one-half (.5) unit per gross acre of area within the area to be developed.
(b) Open Space. At least fifty percent (50%) of the total gross acreage of the Single Family Planned Residential District must be devoted to open space. Open space shall be designated upon the development plan as "Maintained Passive Open Space", "Recreational Open Space" and "Unmaintained Passive Open Space" upon the basis of the definitions, purposes, requirements and conditions set forth in this Ordinance, excepting that, notwithstanding anything to the contrary, public or private golf courses, with all buildings and club houses incident thereto, may be designated as "recreational open space" when integrated into a golf course community as permitted by this section. Such open space shall be designed to provide active recreation, passive recreation, the preservation of natural site amenities or any combination thereof. Any buildings, structures and improvements to the open space must be appropriate to the uses which are authorized for the open space, having regard to its topography and unimproved condition. The open space shall be of a size, shape and location which is conducive to use by residents of the property within the Single Family Planned Residential District. Public utility and similar easements, rights-of-way for streets and roads, and right-of-ways for water courses and other similar channels are not acceptable for common open space dedication unless such land or right- of-way is usable as a trail or similar purpose and has been approved by the Zoning Commission. Storm water retention or detention facilities are acceptable for dedication as Maintained Passive Open Space, provided such facilities do not exceed ten percent (10%) of the total open space required. The responsibility for the maintenance of all open spaces shall be specified by the developer in writing before approval of the development plan. The open space reserved in a Single Family Planned Residential District shall be dedicated to, and permanently owned by, a homeowners' association that shall have title to the land for the use of each owner who buys property within the development. Such open space shall be used only for the purposes for which it is designated upon the approved development plan, and in accordance with the approved development plan. The legal articles relating to the organization of the homeowners' association are subject to review and approval by the Zoning Commission and shall provide adequate provisions for the perpetual care and maintenance of all common areas. Such legal articles shall be inserted into the chain of title of the land within the Single Family Planned Residential District. All open space shall be prohibited from further subdivision or development. This shall be done by placement in a reserve and notation on the final plat or by other declaration or agreement in the chain of title to such property, the same to be in a form acceptable to the city attorney.
(c) Lot Width. There shall be a lot width of seventy-five (75) feet or more at the front line of the dwelling, and such lot shall have access to and abut on an adjoining approved street or road for a distance of sixty (60) feet or more.
(d) Lot Depth. There shall be a lot depth of one hundred thirty-five (135) feet or more extending from the front line of the lot to the rear line of the lot.
(e) Side Yard Setback. No building or structure shall be located closer than twelve and one half (12 1/2) feet to any side lot line, and the total of the side yards shall be twenty-five (25) feet or more.
(f) Building Setback. No building or use shall be located closer to the right-of-way line or centerline of the adjacent public or private road than thirty (30) feet.
(g) Rear Yard Requirement. No structure shall be located closer than thirty (30) feet to the rear line of any lot. Children's play sets shall be exempt from this restriction if located at least five (5) feet from the rear line.

(i) Access. A minimum of two forms of ingress and egress are required unless approved by the Planning and Zoning Commission.
(j) Landscaping. Reference Chapter 1183 for landscaping standards. Landscape plans shall be submitted with the subdivision plat and shall be subject to approval in the same manner required of the subdivision plat. All such landscaping shall be maintained and kept in accordance with the landscape plan as submitted, and such maintenance and upkeep shall be the responsibility of the owner of such yard, space or area. All vacant lots shall be kept seeded or maintained in such manner as to prevent erosion of the property and excess drainage onto adjoining lands.
(k) Parking. Off street parking shall be provided, at the time of construction of the main structure or building, with adequate provisions for ingress and egress according to the development plan. In preparing and approving the parking plan the provisions of Chapter 1175 shall, when appropriate, be incorporated.
(l) Signs. Signs shall comply with Chapter 1177. Signs permitted in SR-1, SR-2, UR-1 and UR-2 districts are permitted in PUD districts.
(m) Building Height Limits. No building in this district shall exceed thirty-five (35) feet in height measured from finished grade established not closer than fifteen (15) feet to the exterior wall of the structure. Barns, silos, grain handling conveyors, church spires, domes, flag poles and elevator shafts, are exempted from any height regulation and may be erected to any safe height.

No single family structure shall back up to an existing roadway and shall face the boulevard, collector or local street.
(p) The Planning and Zoning Commission and/or the Johnstown City Council may impose special additional conditions relating to the development with regard to type and extent of public improvements to be installed; landscaping, development, improvement, and maintenance of common open space; and any other pertinent development characteristics.
