Install, maintain, or remove access ramp

An access dam provides a connection across a waterway and is of great importance for the infrastructure and access to a site. Because these dams can affect natural water flows, it is important that they are carefully designed, maintained, and, if necessary, removed. That is why the water board has established rules, laid down in the Water Authority Regulations

On this page, you can read about the rules and what you need to do to comply with them. 

Please note: when constructing an access dam, it is mandatory to install a culvert. For more information, see the page Installing, maintaining, or removing a culvert, siphon, or siphon pipe.

Rules for your situation

The location and the work you will be performing determine whether one of the following situations applies to you:

  • Permit requirement: You need a licence conditions before you can start your work. This applies to work on flood defenses, the protection zone immediately adjacent to them, primary surface water, and waterways managed by the water board.
  • General rules with information obligation: If no permit is required, general rules may still apply. You must comply with certain rules when carrying out your work. In most cases, you must also provide the water board with information about your work. This must be done in advance and sometimes also after completion.
  • Compliance with the duty of care: There are no general rules that apply to your work. However, you must comply with the applicable duty of care.

Always perform the Permit Check on the Omgevingsloket website to check which situation applies to your work.

Permit check – Step by step

To find out what applies to your work, we always recommend that you do the Permit Check. That way, you will immediately know which rules apply. 

License check

Below you will find what is expected of you for each step of the Permit Check and useful tips for the best results.

Beforehand: Keep information about your plans handy

Make sure you have the details of your plans to hand. This information can help you answer the questions correctly.

Step 1: Select location

Select the location of your work. Search by address or zoom in on the map. Then use the "Draw an area on the map" option in the upper left corner of the map to accurately indicate the location.

Tip: Accurate drawing of the location ensures a better result from the Permit Check.

Step 2: Selecting activities

Select the work you want to perform. Search for "Access dam" and choose from the following options:

  • Constructing or modifying a dam, culvert, or dam with culvert
  • Remove dam, culvert, or dam with culvert

Will you be performing any additional work during your project? If so, please select these activities as well.

Step 3: Answer questions

Go through the questionnaire and answer the questions. Questions that are not relevant to your situation will be omitted. Read the instructions carefully to answer the questions correctly.

Tip 1: Not all explanations are displayed immediately. There is a green i that you can click on to display the explanation.

Tip 2: Has there been a recent change in your area and are you unsure whether the maps shown in the questionnaires are accurate? If so, please contact the water board.

Step 4: Permit check result

You will see an action list. Under the following headings of the action list, you will find what applies to your situation:

  • licence : If a license is required
  • Reporting and providing information: If general rules with an obligation to provide information apply.

If none of the water board's points are included in the result, then you only need to comply with the duty of care. 

Tip: Use the 'Download action list' button to download it. Add it later as an attachment to your permit application or when you provide information. This will help us process your application more efficiently.

Continue: Start application

Use the 'Apply and prepare' button to start your application or provide information right away. The location and the correct forms will then be selected immediately based on the result.

Tip: Even if you do not want to continue with your application immediately, it is useful to start anyway. After completing step 1, your progress will be saved and you can continue later with the correct forms.

General rules

If general rules apply to your situation, you may authorisation your activities without authorisation . However, you must comply with the rules that apply to this activity. These rules are outlined below:

Rules for placing an access dam

When placing an access dam, the following rules apply:

Inform the water board

  • You will provide us with information about the planned work fifteen working days before placing an access dam.
  • Within two weeks of completing the work, you will provide us with information:
    • How the work was carried out
    • Any changes to the information provided in the initial report

Construction and maintenance of access dam

Under "Data and documents," you will find the information you need to provide.

Surface water body storage capacity

If more than 35 m² of storage capacity is lost due to the construction of an access dam, this loss must be compensated. This is done within the same water level area. Compensation takes place by:

  • The widening of an existing surface water body, or
  • Digging new surface water.
  • The newly excavated or widened surface water must have at least the same surface area as the lost area.
  • The storage capacity is determined based on the highest applicable water level. This water level is included in the locally applicable water level decree.

Maintenance of the surface water body

In order to continue to maintain the surface water body properly, the location of the structure must comply with the Maintenance Guidelines of the Water Board Regulations. For more information, see the page: Maintenance of watercourses and engineering structures: what you need to do.   

For more information about local water levels, see the page: Water level decisions 

Rules for removing an access dam

When removing an access dam, the following rules apply:

Inform the water board

You will provide us with information about the planned work fifteen working days before the access dam is removed. 

Removing the access dam

An access dam that no longer serves its purpose will be removed in consultation with the water board.

Maintenance of the surface water body

In order to continue to maintain the surface water body properly, the location of the structure must comply with the Maintenance Guidelines of the Water Board Regulation. For more information, see the page: Maintenance of watercourses and engineering structures: what you need to do.

Fulfilling duty of care

The duty of care applies to all activities. The duty of care obliges you to prevent damage to water safety, water quality, and water quantity. If you comply with the permit requirement or the general rules, you will usually also comply with the duty of care. If these rules do not apply, you must assess for yourself whether your activities comply with them. If in doubt, you can request a customized regulation. Duty of care: what you need to know.

Customized prescription

You can request a customized regulation via the Omgevingsloket (Environment Desk) if you deviate from the rules or need help to comply with the duty of care. The customized regulation provides clear guidelines so that you always comply with the duty of care. See the page Customized regulation: what you need to know

You can request a custom prescription for the following rules:

  • Construction and maintenance of access dam
  • Surface water body storage capacity
  • Maintenance of the surface water body
  • Duty of care, if you want more clarity on how to fulfill your duty of care

Applications

Below you will find step-by-step instructions on what is expected of you, along with useful tips on how to do this as well and as completely as possible. If you have continued with the application after the Permit Check, steps 2 and 3 have already been completed for you.

Beforehand: Prepare well

Make sure you are well prepared before you start the application or provide information. Gather all the information and documents you need in advance. 

Tip: You can also submit a draft request before submitting your application or providing the requested information. This allows you to check whether your application is complete.

Step 1: Create a project

Give your project a name and describe the work you want to carry out. This will help the water board to classify your application correctly.

Tip: Keep the description clear and specific to reduce the likelihood of additional questions.

Step 2: Select location

Select the location of your project by searching by address or zooming in on the map. Then use the "Draw an area on the map" option in the upper left corner to specify the location accurately.

Tip: Zoom in sufficiently to draw the area as accurately as possible.

Step 3: Select activities

Select the forms for the activities required for your application or to provide information. Search for 'Access dam' and choose one of the following options:

  • licence application: Installing, maintaining, or removing an access dam – licence application licence Water Board)
  • Compliance with information requirements: Installing, maintaining, or removing access dams – Information (Water Board)
  • Request for customized regulation: Install, maintain, or remove access dam – Customized regulation (Water Board)

Select all other forms that are required for your project.

Tip: Make sure you have selected all the necessary forms to submit a complete application. This will save you from having to supplement your application later on.

Step 4: Answer questions

Answer all questions as completely as possible. This will enable us to process your application or the information you have provided correctly. It will also prevent additional questions later on during the processing. Questions that are not relevant to your project will be omitted automatically.

Tip: Take your time to fill in the questions carefully. This ensures that only the important attachments will be requested in the next step.

Step 5: Add documents

Attach the requested documents. If a document contains multiple parts, it only needs to be attached once per form. Each form is distinguished by its name, so it is clear which attachment belongs to which application.

Tip: Check that the documents meet the requirements (such as file type and size) of the Omgevingsloket.

Step 6: Fill in your contact details

Please enter your contact details. A phone number and email address are required. Without this information, your request cannot be processed.

Tip: Use contact details where you can be reached quickly in case of any additional questions.

Step 7: Submitting your application

Decide whether you want to submit the application or information immediately or submit a draft request first. A draft request is useful if you want to check that all the information is correct before the process actually starts.

  • Step 7a: Select which forms you want to submit, if there are several. It is not mandatory to submit everything at once. For example, you can choose to apply licence a licence first and comply with the information obligation later.
  • Step 7b: Choose whether you want to submit a final application or would prefer to submit a draft request first. With a draft request, the application procedure period does not start yet, which gives you time to supplement any missing information.
  • Step 7c: In the last section, you answer questions about contact with your neighbours other parties involved in your project. There are also a few questions about any additional information you can provide to clarify the application.

Tip: Opt for a draft request if you are still unsure about the completeness of your application.
