Beleidsregel Parkeernormering gemeente Westland 2018 – Parking Standards and Regulatory Framework
The Beleidsregel Parkeernormering gemeente Westland 2018 is a formal policy rule issued by the College of Mayor and Aldermen of the Municipality of Westland, Netherlands. Effective from March 23, 2018, this document serves as the legal assessment framework for parking requirements in all planning decisions, including zoning plans (bestemmingsplannen), out-of-plan deviations, and environmental permits (omgevingsvergunningen). It ensures that spatial developments provide sufficient parking capacity to maintain traffic safety and accessibility while preventing the inefficient use of public space.
The regulation defines parking standards across various land-use functions such as residential, commercial, retail, health care, and education. It categorizes the municipality into four distinct geographic zones: hoofdcentrum (main center), dorpscentrum / schil hoofdcentrum (village center/center shell), Schil dorpscentrum / 2de schil hoofdcentrum (outer shell), and Westland overig (remaining areas). These standards are largely based on CROW publication 317 but includes specific local adaptations for the Westland context, including glasshouse horticulture (glastuinbouw) and specific social-cultural facilities.
This document provides the methodology for calculating parking demand using occupancy percentages (aanwezigheidspercentages) and defines how parking supply on private property must be measured. It also outlines the conditions under which a developer may deviate from the requirement to provide parking on-site, including maximum acceptable walking distances and contribution schemes for public parking infrastructure.
Calculation of Parking Demand
The total parking demand for a development is determined based on the functions added or removed, utilizing the standards found in Bijlage 1. For residential functions, the standard is influenced by the price category and the specific geographic zone of the project.
- Occupancy Percentages: These percentages account for the fact that parking demand fluctuates throughout the week. Peak moments for different functions (e.g., residential vs. office) often do not coincide, allowing for double use of parking spaces.
- Function Categorization: Standards are provided for Wonen (housing), Werken (offices and industry), Winkelen (retail and groceries), Onderwijs (education), and Horeca (hospitality).
- Calculation Units: Requirements are typically expressed per 100 m² of Gross Floor Area (bvo), per unit, or per treatment room, depending on the specific function.
Parking Supply on Private Property
Article 5 defines how existing or planned parking facilities on a developer's own terrain contribute to the total parking supply. The regulation acknowledges that theoretical capacity does not always match actual use, particularly for residential driveways and garages.
- Single Driveway: Calculated as 1.0 parking space.
- Long Driveway (min. 10.50m): Calculated as 1.3 parking spaces.
- Double Driveway (min. 5.50m wide): Calculated as 2.0 parking spaces.
- Attached Garage: Calculated as 0.5 spaces if combined with a driveway, as garages are often used for storage rather than parking.
- Detached Garage Box: Calculated as 0 spaces towards the required supply.
Deviations and Public Space Requirements
If a development cannot realize the required parking on its own terrain, Article 6 allows for an integral assessment to determine if public space can absorb the demand. This assessment considers the existing parking pressure and the availability of public spots within specified walking distances.
- Residential Walking Distance: Maximum 100 meters.
- Work and Retail Walking Distance: Maximum 400 meters.
- Healthcare and Education: Maximum 100 meters.
- Leisure/Recreation: Maximum 150 meters.
Deviations may require the developer to pay a financial contribution for the realization of extra parking spaces in the public domain, provided those spaces can be realized within the acceptable walking distances for the intended use.
Frequently Asked Questions
What is the visitor parking requirement for a standard house in Westland?
For residential units, the visitor share is typically calculated at 0.3 spaces per home, which is included in the total parking standard.
How does the municipality count a garage when determining parking supply?
An attached garage with a driveway counts as 0.5 spaces, while a detached garage box is not counted (0) towards the official parking supply.
What are the dimensions required for a new parking space on private property?
A single driveway must be at least 5.50m deep and 2.80m wide. A long driveway requires a depth of at least 10.50m.
Which geographic zones have the lowest parking standards?
Generally, the hoofdcentrum (main center) zone has lower parking standards due to higher urban density and better accessibility by other transport modes.
How is parking demand calculated for a mixed-use building?
The demand is calculated by summing the requirements for each function while applying aanwezigheidspercentages (occupancy percentages) to find the collective peak demand moment.
What happens if a project involves a building with a history of illegal use?
If the current use is illegal, the calculation of the 'existing' parking demand is based on the legally permitted function as defined in the zoning plan or the use from three years prior.
