Herziening Nota Parkeernormen 2018 – Parking Standards for Kaag en Braassem
The Herziening Nota Parkeernormen 2018 is a policy rule issued by the Municipality of Kaag en Braassem, Netherlands. Established by the Board of Mayor and Aldermen on June 3, 2025, and effective from June 24, 2025, this document serves as the regulatory framework for parking requirements in spatial developments. It is based on Article 4:81 of the General Administrative Law Act (Algemene wet bestuursrecht) and replaces the previous 2018 version to provide higher precision in assessing diverse development types and the application of 'settling' (salderen) existing parking needs.
The regulation governs new construction, renovations, functional changes, and restructuring projects. It defines specific requirements across three distinct geographical zones: Centrum (Roelofarendsveen center), Rest bebouwde kom (other built-up areas), and Buitengebied (outlying areas). The document incorporates national guidelines from CROW publication 317 and CROW publication 182 while adapting them to local circumstances, such as the municipal average car ownership of 1.21 cars per household.
Professional users, including architects and developers, utilize this document to determine the exact number of parking spaces required for residential, commercial, and social projects. It details technical dimensions, walking distance thresholds, and shared-use percentages to ensure accessibility and spatial quality within the municipality.
Development Categories and Definitions
The policy distinguishes between four primary types of spatial developments to determine how parking demand is calculated:
- Functiewijziging: Changes to the use of an existing building without demolition.
- Uitbreidingsontwikkeling: Extensions or additions that increase the intensity of a function's use.
- Herstructurering: The demolition of existing structures followed by the realization of new buildings with equivalent or different functions.
- Nieuwbouwontwikkeling: Construction on previously undeveloped plots.
For function changes, expansions, and restructuring, the calculation only accounts for the net increase in parking demand. For new builds, the full parking norm applies as the previous function is assumed to have had zero parking demand.
Technical Design and Dimensions
Parking facilities must meet specific technical standards regarding dimensions and accessibility to be credited toward the parking requirement:
- Parallel parking spaces: Minimum dimensions of 2.1 x 6.0 meters.
- Perpendicular (angle) parking spaces: Minimum dimensions of 2.5 x 5.2 meters.
- Indoor garages: Must comply with NEN 2443 standards.
- Terrain parking: Must comply with ASVV 2012 and the municipal Leidraad Inrichting Openbare Ruimte (LIOR).
Public parking spaces within the project area may be counted toward the total requirement. If on-site parking is impossible, the municipality may grant a waiver involving a contribution to the parking redemption fund (Nota vereveningsfondsen).
Shared Use and Presence Percentages
To optimize space, the regulation permits 'shared use' (dubbelgebruik) when a project combines multiple functions with peak demands at different times. Calculation is based on the presence percentages in Annex 3:
- Residential: 100% presence during work nights; 60% on Saturday afternoons.
- Offices/Businesses: 100% during workdays; 0% on evenings and weekends.
- Retail: 30% on work mornings; 100% on Saturday afternoons.
- Sports facilities: 25% during workdays; 100% on weekday evenings and Sundays.
Shared use reduction is only applicable if the total parking requirement exceeds 20 spaces and if the parking remains publicly accessible for all users.
Walking Distances and Accessibility
Parking spaces must be located within an acceptable walking distance from the main entrance of the function they serve. Table 4.3 defines these thresholds:
- Residential: 100 meters maximum.
- Retail: 200 to 600 meters (depending on errand type vs. fun shopping).
- Work/Office: 200 to 800 meters.
- Healthcare and Education: 100 meters maximum.
Frequently Asked Questions
How are decimals handled in the parking requirement calculation?
Calculations are always rounded up to the nearest whole number at the end of the calculation process (e.g., 35.2 spaces becomes 36 spaces).
Is a parking test required for home-based businesses?
No parking test is performed for small-scale home-based professions (e.g., accountants, speech therapists), provided they have no personnel and no disproportionate impact on the neighborhood.
What is the requirement for disabled parking spaces?
At least 5% of public parking spaces in parking lots must be designated for disabled users, with a minimum of one space per lot, located as close as possible to the building entrance.
Can existing parking spaces be used to meet the requirements of a new function?
Yes, through 'settling' (salderen), the existing parking demand of the previous function can be subtracted from the new demand to determine the net requirement.
What happens if a specific function is not listed in the parking annex?
If a function is not in Annex 2, the municipality uses national CROW guidelines or requires a specific parking study to determine a tailored norm.
What are the specific parking zones in Kaag en Braassem?
The municipality is divided into three zones: Centrum (restricted to Roelofarendsveen center), Rest bebouwde kom (other urban cores), and Buitengebied (rural areas).
