  • NPD Credit 5: Reduced parking footprint

    Intent

    To minimize the environmental harms associated with parking facilities, including automobile dependence, land consumption, and rainwater runoff.

    Requirements

    For new nonresidential buildings and multiunit residential buildings, either do not build new off-street parking lots, or locate all new off-street surface parking lots at the side or rear, leaving building frontages facing the circulation network free of surface parking lots (alleys may be exempted).

    Use no more than 20% of the total development footprintThe total land area of a project site covered by buildings, streets, parking areas, and other typically impermeable surfaces constructed as part of the project. area for all new off-street surface parking facilities, with no individual surface parking lot larger than 2 acres (0.8 hectare). For the purposes of this credit, surface parking facilities include ground-level garages unless they are under habitable building space. Underground or multistory parking facilities can be used to provide additional spaces. On-street parking spaces are exempt from this limitation.

    Provide carpool or shared-use vehicle parking spaces equivalent to at least 10% of the total off-street parking spaces for each non-residential and mixed-use building on the site. Such parking spaces must be marked and within 200 feet (60 meters) walking distance of entrances to the building served.

Project with no off-street parking spaces

Hi,

Our project has no off-street parking spaces. Does this project automatically meet the third requirement of this credit, "Provide carpool or shared-use vehicle parking spaces equivalent to at least 10% of the total off-street parking spaces for each non-residential and mixe-use building on the site"?

Thank you,
Noriko Yasuhara

Hi Noriko. For this credit there are four types of off-street parking: surface, underground, multi-story exclusively parking, and multi-story with ground level parking beneath habitable building space. When you say your project has no off-street parking spaces you may be referring only to the surface type, and I imagine you at least have the underground type. Regarding the credit requirement for carpool spaces, this requirement must be satisfied using one or more of the four parking types. And Step 4 of the Reference Guide step-by-step guidance states "Projects that do not include any new parking must have existing parking on the site that complies with carpool and shared-vehicle parking requirements." So the carpool requirement has to be satisfied with some kind of new and/or existing parking even when new surface parking is not constructed.

Hi Eliot,

Thank you for your instruction.

I would like to clarify that if a project includes all of the 4 parking types, is it acceptable to provide carpools or van pools for only one of 4 parking types? If so, the required number of parking spaces is calculated based on the number of all parking spaces including all types of parking spaces or parking spaces belong to dedicated type?

Thank you for your furthrer clarififation in advance.

Dear Noriko, I am glad to get your follow-up question because I need to revise the conclusion of my previous message. After talking with USGBC staff about the Reference Guide Step 4 requirement that makes carpool parking a precondition for earning the credit, they have agreed to rephrase Step 4 to say "Projects that do not include any new parking must ensure that any existing parking on the site complies with carpool and shared-vehicle parking requirements." Therefore, the carpool requirement does not have to be met if a site does not have any existing off-street parking, and if no new off-street parking of any type is being constructed.

Regarding your follow-up question, each building's total required off-street spaces are determined by the municipal code without regard to the four off-street types, and that total number determines the 10% required for carpool spaces. That 10% can be met by any one or more of the four types of off-street parking as long as the spaces are within 60 meters of the building served.

Hi Eliot,

I found on P238 of ND v4 reference guide that "multi-level parking structure Elements carrying either vertical or horizontal loads (e.g., walls, roofs, and floors) that are considered structurally sound and nonhazardous.(not subject to credit requirement)". Can parking structure and parking spaces under the buildng be excluded from the calculation?

Hi Noriko, yes, multi-story and underground parking are excluded from the "20% of development footprintThe total land area of a project site covered by buildings, streets, parking areas, and other typically impermeable surfaces constructed as part of the project." calculation. This is confirmed on page 237 under Step 6 where the second major bullet and its first sub-bullet exclude multi-story and underground parking.

Hi Eliot,

I see. So, in Figure 1 on P238, the statement "Multi-level parking structure Elements carrying either vertical or horizontal loads (e.g., walls, roofs, and floors) that are considered structurally sound and nonhazardous.(not subject to the credit requirement)" should be revised to "Multi-level parking structure (not subject to the building frontage requirement)", is it correct?
