Bicycle Racks Best Practices Good Bicycle Racks
• At least 18” wide and 33” tall when installed • Securely anchor to a solid, immovable surface • Provide two points of contact for typical adult or child’s bicycle frame • Allow user to lock frame and one wheel using standard U-lock • Constructed of steel pipe or tubing • Galvanized with a powder coat finish to protect against corrosion (outdoor racks)
Commonly Accepted Rack Types • • • •
Inverted-U or hoop rack Circular or ring rack Vertical racks (indoor only) Double decker racks (indoor only)
Circular
Inverted-U
Inverted-U racks are a common choice.
Vertical
This rack provides a wide base to support both the wheel and the frame of a bicycle.

Notes: 1. All racks must be installed to offer a minimum of 33” of height and 18” of width. 2. This list is not comprehensive. Any racks that meet the standards in this guide will be considered for approval.
Arlington County Bicycle Parking Guidelines | Page 4
Layout and Installation Sidewalk Installation In-Ground Mount (Preferred Method)
In Brick or Stone Pavers • Legs must be 9” deep in a 12” x 12” concrete block • Block must be under 6” of pavers
Surface Mounted Racks
• Minimum of two fasteners per mounting plate • Concrete pad must be 4” deep • Use tamperproof studs or anchors
In Concrete • Tubes must be minimum 9” deep in concrete
Arlington County Bicycle Parking Guidelines | Page 5
Layout and Installation Sidewalk Installation Continued Installing on a Slope
• Always ensure that the legs of the rack are vertical • Preferred method is using in-ground racks • For surface-mounted racks, the use of shims may accomplish this task
Hardware
• Exposed threads/nuts should be stainless and not galvanized Acceptable Hardware • Concrete spike • Security nuts • Threaded expansion anchor or Rawl stud • Metal shims
Concrete spike
These inverted-u racks were installed with one leg deeper than another, with the result being an even installation on a slope.
Security nuts
Threaded expansion anchor/Rawl stud
These inverted-u racks were surface-mounted on a slope with no shims, and the installation is tilted.

Aisle Width - single 5 ft level Aisle Width 7 ft Double-decker racks On-center distance 3 ft Parallel or angled racks Distance - end to end U 8 ft racks Distance from any 2 ft obstruction Vertical clearance for See manufacturer’s specs Double-decker rack Definitions Single level: All racks either on ground level or vertical racks. Double-decker: Any rack that requires the bicycle to be rolled or lifted up onto a second level. Parallel U rack configuration
End to end configuration (on sidewalk) Angled U rack configuration
Arlington County Bicycle Parking Guidelines | Page 7
Short-Term Visitor Parking (Class III) Class III Parking Definition
• Intended for short-term use by visitors • Outside, but near a building entrance • Are secure by means of bicyclist’s own lock
Requirements
• Installed within 50 feet of an entrance • Leaves pedestrian paths and vehicle rights of way clear • Highly visible
Other Considerations
• Often placed in line with utility strips and tree pits • Referred to as Class II when covered by roof or overhang
Typical Class III Ratios for Arlington Site Plans Land Use
Number of Class III Spaces
Residential Office Retail
1 space for every 50 units 1 space for every 20,000 sf 2 spaces for every 10,000 sf, up to 50,000 sf, then 1 space for each additional 12,500 sf Hotel 1 space for every 50 units Educational 1 space for every 10 High School students, 15 Middle School students, and 20 Elementary School students Note: These ratios are the most current. Please verify for your project in the site plan conditions.

Long-Term Secure Parking (Class I) Class I Parking Definition
• Intended for long-term or overnight storage • Typically provided for tenant employees or residents
Requirements
• Protection from weather • Security of locked room or cage • Ability to lock bicyle to a rack within the room or cage
Typical Class I Ratios for Arlington Site Plans Land Use
Number of Class I Spaces
Residential Office Retail Hotel
1 space for every 2.5 units 1 space for every 6,000 sf 1 space for every 25,000 sf 1 space for every 10 hotel rooms Educational 1 space for every 10 employees Note: These ratios are the most current. Please verify for your project in the site plan conditions.

Long-Term Secure Parking (Class I) Location Choices Best Option
Second Best Option
Third Best Option
Special Scenarios
Fully enclosed ground floor room with sidewalk access Pros: Clean, discrete, highly secure, less conflict with cars Cons: May take up leasable square footage
Cage in a garage Pros: Secure Cons: Bikes are visible to potential thieves, conflicts with cars, can be uninviting
Fully enclosed room in garage Pros: Discrete, highly secure Cons: Conflicts with cars, can be uninviting
Bike Lockers Pros: Secure, protection from weather (for bicyle) Cons: Bicyclist not protected from weather, not space efficient
Arlington County Bicycle Parking Guidelines | Page 10
Long-Term Secure Parking (Class I) Room Design and Facilities Room Design Requirements
• At least 30% of bicycle parking must be horizontal and at ground level • Cage walls must be made of industrial grade expanded metal or welded wire mesh • Doors must be hollow metal • Doors must use a heavy-duty cipher lock or electronic lock • Cages only: door handles and locks supplemented by sheet metal plating, 3 feet in each direction, as needed to prevent tampering • Cage walls must reach all the way to ceiling
For Non-Residential Uses
Showers and lockers support Class I facilities for bicycle commuters.
Item
Requirement
Lockers (quantity)
One locker per gender, per Class I bicycle parking space Minimum 12” wide, 18” deep, 36” tall One shower per gender for every 50,000 sf, up to 3 showers per gender 24-hours
Lockers (dimensions) Showers (quantity) Accessibility
This cage adapts to the garage bulkhead.
Lockers provided in the bicycle cage.

Plan Review Steps to Take Rough Guide to Bicycle Parking in New Construction Process
1. Depict interior bike parking on architectural plans 2. Depict exterior bike parking on civil engineering plans (Civil and Landscape plans must match) 3. Submit with complete plans to appropriate department for review 4. Make revisions to plans as required (typically for Footing to Grade Permit) 5. Order materials 6. Schedule installation coordination meeting with TDM staff prior to install for layout guidance and troubleshooting 7. Complete installation 8. Schedule inspection of installation with TDM staff prior to need for release of First Certificate of Occupancy
Rough Guide to Bicycle Parking in Renovation or Retrofit Process
1. Obtain copy of relevant plan sheets for area on property where bike rack installation is being considered 2. Schedule site selection meeting with TDM staff for location and layout guidance and troubleshooting 3. Submit drafts of revised plan and detail drawings to TDM staff for review 4. If necessary, submit approvable drawings as a part of complete application for administrative change, through Zoning 5. If administrative change is approved, order materials 6. Schedule installation coordination meeting with TDM staff prior to install for layout guidance and troubleshooting 7. Complete installation 8. Schedule inspection of installation with TDM staff Arlington County Bicycle Parking Guidelines | Page 12

Plan Review Additional Requirements Architectural and Civil Plans
For each type of bicycle rack, provide a construction specification sheet with information from the manufacturer, and hardware schedule. Where needed for clarity, there should be drawings depicting ceiling clearance above the racks.
Arlington County Bicycle Parking Guidelines | Page 16
Practices to Avoid Common Mistakes Bad Bicycle Racks
• Require excess lifting • Have unintuitive design (the simpler the better) • Too narrow to support wheel and frame (18” minimum) • Easily dislodge from the ground (remember tamperproof hardware) • Constructed of materials that will rust and corrode • Create conflict with the handlebars
Unacceptable Rack Types • • • • •
Wave racks Fence racks Spiral or corkscrew racks Coat hanger racks Wheel block racks
Wave
This rack is not functional due to its proximity to obstructions.
Coat Hanger
Fence
Artistic racks can have designs that are confusing to cyclists.
