(A) General. This standard shall apply to all parking lots located within the zoning jurisdiction of the City of North Platte. Title 28 CF.R. part 36 (ADA Accessibility Guidelines), Title 156, Nebraska Administrative Code - Nebraska Accessibility Requirements; and the City of North Platte, Nebraska Design Standards for Screening and Landscaping; generally apply to the design of parking lots in the City of North Platte.
(Prior Code, § 56-524)
(B) Policies. All plans for the construction of parking lots shall be reviewed and approved by the Department of Engineering and landscape design shall be reviewed and approved by the city's Development Department.
(Prior Code, § 56-525)
(C) Design.
(1) Layout.
(a) The size, location and orientation of the parking spaces and aisles shall conform to the details shown in Figure PL-1. Barriers and islands should generally conform to the details shown on Figure PL-2.
(b) Required accessible parking spaces, including van-accessible spaces, shall be located, designed, marked and signed in conformance with the requirements of 28 CF.R. part 36 (ADA Accessibility Guidelines) and Title 156, Nebraska Administrative Code - Nebraska Accessibility Requirements.
(c) Upon completion of construction of the parking lot, the required parking spaces shall be marked on the parking lot surface with paint formulated for that purpose and in accordance with the approved layout. Parking spaces provided in excess of the number required under this code or as required by conditions of a special permit need not be marked, or they may be marked to lesser standards.
(2) Driveway approaches. Driveway approaches shall conform to the requirements of this code.
(3) Parking barriers.
(a) Parking barriers must be provided around parking lots to prevent the parked vehicles from overhanging the required yards where parking is prohibited, sidewalk space, public streets, public alleys or other public or private property and to protect any required landscaping or landscape screen planting. Approved barriers include the following types:
1. Poured concrete curb, nominal 6 inches by 6 inches (152 x 152 mm) exposed;
2. Fence, minimum 30 inches (762 mm) height, wire fabric, solid wood, post and rail and the like;
3. Masonry, modular segmental block or concrete wall, minimum 30 inches (762 mm) height;
4. Beam guardrail;
5. Post and cable guardrail; and
6. Precast concrete wheel stop, firmly and permanently anchored.
(b) Other barriers, which fulfill the required function, maybe permitted, subject to approval by the Engineering Department. Barriers must be located to contain the parking within the approved parking lot. When a concrete curb or precast wheel stop is used as a barrier for perpendicular or angle parking, it must be offset at least 2 feet (0.6 m) from the edge of the parking lot to allow for the front overhang of the vehicle.
(4) Drainage.
(a) Parking lots shall be designed to properly manage the surface drainage accumulating on and flowing onto the site.
(b) For new parking lots containing 6,000 square feet (557 square meters) or more and which are located within 150 feet (45.7 m) of, or reasonably accessible to, an existing storm sewer or other drainage way, including open channels and creeks, but excluding roadway gutters, the parking lot must be graded and surfaced such that stormwater runoff from the site is not allowed to discharge through the driveway approaches onto the public street or other property, but is collected on the site by an internal drainage system located on the site and carried to that existing storm sewer. Use of parking lot surfaces and surrounding landscaped areas to provide stormwater detention is encouraged.
(c) Parking lot drainage facilities and appurtenances shall be designed and constructed in conformance with the requirements of this code.
(5) Surfacing.
(a) All new parking lots created after January 1, 2002, shall be designed/developed and surfaced with portland cement concrete pavement, asphaltic concrete pavement, brick or modular pavers, open landscaping paving blocks, pervious asphalt surfaces with subdrains or other permanent surfacing approved by the Engineering Department. In parking lots and drive areas where moderate to heavy truck traffic is anticipated, the structural capacity of the surfacing should be analyzed by the design engineer and property owner and the pavement structure designed accordingly. The instances may require thicker or reinforced sections and special subgrade treatments.
(b) Non-permanent parking lots maybe graveled as approved by the city and shall be maintained in a dust-free condition during the period they are permitted.
(6) Lighting and lighting performance standards.
(a) The purpose of parking lot lighting is to provide adequate visibility within the parking lot and to enhance the security and safety of the lot users. It should not cause interference to traffic on public thoroughfares or encroach on the visual privacy of adjacent residents.
(b) All exterior lights shall be designed, located, installed and directed in such a manner as to prevent objectionable light trespass and glare across the property lines and/or disability glare at any location on or off the property.
(c) All parking area lighting shall be full cut-off type fixtures.
(d) All building lighting for security shall be full cut-off type or a shielded type, not allowing any upward distribution of light. Flood lighting is discouraged and, if used, must be shielded.
(e) Outdoor non-residential lighting adjacent to residential property shall be installed to ensure that no direct light source shall be visible at the property line at ground level or above.
(f) Area lighting shall be conducted so that the light source is directed away from areas in residential use or shall be controlled so that candlepower per 1,000 lamp lumens does not numerically exceed 50 lamp lumens (5%) above the vertical angle of 78 degrees above nadir; or emit more than 150 foot-candles per unit projected surface area of the luminaire above a 78 degree vertical angle.
(g) Illumination resulting from outdoor lighting shall be conducted so that direct or indirect illumination does not exceed 1.0 horizontal foot candles at a boundary line with an adjacent residential zoning district.
(h) Measurements shall be made with a cosine corrected photoelectric photometer having a spectral response corrected to fit the luminous efficiency curve established by the International Commission on Illumination.
(i) In areas where non-residential development abuts residential development, site lighting plans shall be submitted to the city which include:
1. Site plan showing foot candle lighting on the site and across property lines. Fixture type and location shall be shown on the plan; and
2. A COMCheck, as required by the State of Nebraska Energy shall be provided.
(j) Any variation to the above lighting and light performance standards shall be reviewed and may be approved at the discretion of the City Engineer, City Planner and City Administrator.
(7) Sidewalks. A pedestrian walkway maybe required across or through parking lots by the city's Engineering Department to provide for pedestrian circulation along a direct route to an adjacent sidewalk system. Barrier-free access should also be provided across parking lots and between adjacent pedestrian generators such as commercial or public buildings. Barrier-free access may include providing ramps at curbs, clear walkways between precast wheel stops, and clearly delineated walkways on the parking lot surface. Where the most direct pedestrian route between 2 pedestrian traffic generators is parallel to an internal roadway having a projected average daily traffic volume (ADT) of more than 2,000 vehicles, a separate pedestrian walkway may be required by the city's Engineering Department.
(a) The minimum stall width for all lots shall be 8.5 feet (2.6m).
