On-street Parking

  • Maintenance
    • Wheel stops/curb (parking blocks) - not to be placed for on-street parking as it causes issues with tripping hazard, street sweeping and snow plow removal.
  • MUTCD Section 3B.18 Parking Space Markings
    • “Marking of parking space boundaries encourages more orderly and efficient use of parking spaces where parking turnover is substantial. Parking space markings tend to prevent encroachment into fire hydrant zones, bus stops, loading zones, approaches to intersections, curb ramps, and clearance spaces for islands and other zones where parking is restricted. Typical parking space markings are shown in Figure 3B-17.”

    • On-street parking is most commonly associated with urban or village landscapes and is often metered as a revenue generator as part of a community's parking management program. On-street parking spaces are typically included in the design of the roadway within which they are located and also referred to as 'parallel' parking. Standard dimensions for on-street parallel parking spaces are 8 feet wide by 22 feet long and placed at least 50 feet from any intersection.
    • On-street angled parking is less common and often associated with historic or central business districts with lesser traffic volumes where it also serves as a traffic calming effect. These installations require much more space within the road right-of-way than parallel parking but offer the opportunity to create more stalls within the same length.
    • Back-in angled on-street parking has recently been installed in the Borough of Pottstown. This installation on East High Street converted two westbound travel lanes and on-street parallel parking into one westbound lane, one bike lane and back-in angled parking within the same available space. Installed in 2003, this concept “has helped revitalize the downtown by slowing traffic, providing more parking spaces adjacent to stores, encouraging bicycling, and making it easier for pedestrians to cross the street.”

Diagonal Parking

  • “Diagonal Parking on Public Streets. Requirements for consideration 1) diagonal or perpendicular on-street parking is common in area; 2) existing activities have no feasible possibility of accommodating demand by obtaining adequate parking by off-street parking and parallel curb parking; 3) a hold harmless agreement is prepared and executed by the proponent of the parking, and indicate that the diagonal parking may be required to be removed at the discretion of the Ada County Highway District.” (ACHD Policy Manual - Traffic Engineering 5100-24)

Curb Extensions (Bulb-outs)

  • “Curb extensions (also called bulb-outs) extend the sidewalk into the parking lane to narrow the roadway and provide additional pedestrian space at key locations; they can be used at corners and at mid-block. Curb extensions enhance pedestrian safety by increasing pedestrian visibility, shortening crossing distances, slowing turning vehicles, and visually narrowing the roadway.” (San Francisco Better Streets - Curb Extensions)
  • “Before reducing the width of the proposed bulb-out, consider modifications to land striping across the entire roadway to provide for the above-listed clearances. Since blub-outs are often expensive to construct, they should be sufficiently wide to maximize their benefit. Bulb-outs less than 4 feet in width may not be cost-effective solution as compared to other potential interventions. Curb extensions should not encroach on cyclists' space. Where bike lanes use a painted inside edge, the bike lane should be painted continuously as the bike lane passes the curb extension, and the bulb-out should be set back so that the gutter does not extend into the bike lane. On lower-speed and volume streets where bikes can travel in mixed flow with vehicles, wider curb extensions may be appropriate, but care should be taken not to force cyclists to merge unexpectedly with faster moving cars at the end of the block. If bulb-outs extend beyond the limit of parked cars, additional efforts should be made to ensure their visibility.” (Street Sweeping at Curb Extensions)
  • “Curb extensions should return to the prevailing curb line as sharply as possible to maximize useable space and minimize parking loss, per the following guidelines: Standard return: Standard bulb-outs should be designed with an inner/outer curb radius of 20 ft and 10 ft, sometimes reduced to 15 ft and 10 ft, to enable street sweeping machinery to sweep the entire curbline.” (Street Sweeping at Curb Extensions)

Intersection Pavement Markings

Intersection Crosswalk Markings

  • MUTCD Section 3B.17 Typical Types of Crosswalk Markings
    • “When crosswalk lines are used, they shall consist of solid white lines that mark the crosswalk. They shall be not less than 150 mm (6 in) nor greater than 600 mm (24 in) in width.”
    • “Marked crosswalks should not be less than 1.8 m (6 ft) wide.”
    • Figure 1-0 Uniform Standard Drawings - Clark County Area - Crosswalk Markings - Type II
    • “Stop lines should be used to indicate the point behind which vehicles are required to stop in compliance with a traffic control signal.”
    • Have stop line/bar minimum 4 ft behind the crosswalk, see CCAUSD DWG NO 254 - Crosswalk Markings - Type I
      • Figure 1-0 Uniform Standard Drawings - Clark County Area - Crosswalk Markings - Type I
  • Extend back of curb (BOC) lines into the intersection, then offset 3 feet towards the PC/PT. Chamfer the corner if needed to keep the crosswalk pavement markings a minimum 4 ft from wheelchair ramp.
  • Figure 1-0 Uniform Standard Drawings - Clark County Area - Crosswalk Markings - Type II

Stop Line

  • “If used, stop and yield lines should be placed a minimum of 4 feet in advanced of the nearest crosswalk line at controlled intersections,…” MUTCD Part 3 Markings - Section 3B.16 Stop and Yield Lines
    • “Design Notes: F. See the Utah Manual on Uniform Traffic Control Devices for stop line placement. Stop lines may be angled or staggered (upon approval of the region traffic engineer) in relation to travel direction.”
    • Figure 1-0 UDOT - Crosswalks, Parking, and Intersection Approaches


Painted Median

  • “When crosshatch markings are used on paved shoulders, they shall be diagonal markings that slant away from traffic in the adjacent travel lane. The diagonal markings shall be yellow when used on the left-hand shoulders of the roadways of divided highways and on the left-hand shoulders of one-way streets or ramps. The diagonal markings shall be white when used on right-hand shoulders.” MUTCD Section 3B.24 Chevron and Diagonal Crosshatch Markings
    • Figure 1-0 City of San Jose - On Street Diagonal Parking
    • emailed frank.farshidi@sanjoseca.gov (Dept of Transportation - Pavement Maintenance) asking of painted median has crosshatch markings and what color edge line
      • Shu Su, PE, Associate Engineer in Geometric Design at City of San Jose - Transportation, shu.su@sanjoseca.gov, 408-535-5698 recommended white lines on the right side of the road, yellow lines on the left side. So the painted median will be white instead of yellow.


  • Landscaped planters in the parallel parking lane minimum 6 ft wide and 7 ft depth. (San Francisco - Parking Lane Planters)
  • Why this is a bad idea:
    • difficult to street sweep
    • drainage issues, 90 deg corners will collect water a trash or if you keep a curb opening and grate, will get clogged and require manual cleaning.
    • not enough room for tree roots, eventually the roots will raise the curb and gutter and will eventually have to remove and replace, especially if the tree is thriving.

Wheel Stops

  • City Code - City of Jerome Idaho - 17.26.090: WHEEL BLOCKS
    • Whenever a parking lot extends to a property line, wheel blocks or other suitable devices shall be installed to prevent any part of a parked vehicle from extending beyond the property line.
  • Typically only allowed in parking lots, not allowed in on-street parking (issues with street sweepers, snowplows, bicycles and pedestrian tripping hazard)

    • M. Street Lighting: Streetlights shall be required to be installed at all entrances to a subdivision and at all intersections. Other streetlights must be installed on every street in the subdivision such that all streetlights are at least two hundred fifty feet (250') but no more than four hundred fifty feet (450') from the nearest streetlight on the same street. Cost of conventional wood pole, mercury vapor luminaries and overhead service shall be the responsibility of the developer. Other types or configurations for lighting shall be approved by the administrator and the cost shall be borne by the subdivider.”
    • “All poles placed on the streets of the city shall be placed at the inner edge of the curb line.” (12.20.070: Utility Poles; Location in Streets Generally)


  • J. Sidewalks And Pedestrian Walkways: Sidewalks shall be required on both sides of the street in residential subdivisions and on one side of the street in industrial and commercial subdivisions, except that where the average width of lots, as measured at the street frontage line or at the building setback line, is over two hundred ten feet (210') sidewalks on only one side of the street may be allowed. Pedestrian walkways, when required, shall have easements at least ten feet (10') in width and include a paved walk at least four feet (4') in width.“
