Applying for support for the unsealing of land

If rainwater can infiltrate better, this promotes the renewal of groundwater and relieves the burden on the sewage system. Against this background, the Senator for Climate Protection, Environment, Mobility, Urban Development and Housing promotes the unsealing of surfaces as a contribution to the sustainable use of rainwater.

Funding is provided for the unsealing of sealed surfaces (e.g. overbuilt or impermeably paved) and their conversion into unsealed surfaces (vegetation surface) or water-permeable paved surfaces (partial unsealing or change of pavement). Unsealing must result in complete decoupling of the area from the sewer system. The entire precipitation water accumulating on the unsealed area must be infiltrated decentrally on site.

Funding is available for up to one third of the eligible costs of a system, up to a maximum of 3,000 euros. The maximum subsidy per square meter of unsealed area is 12.50 euros. In the event of unforeseen additional costs during the construction phase, a subsequent grant can be applied for in writing. However, the total subsidy of 3,000 euros may not be exceeded. Own contributions are not taken into account for the subsidy.

Requirements

Prerequisites for funding are that

• the property is located in Bremen or Bremerhaven,
• the area to be unsealed is larger than 10 square meters,
• the applicant is the owner of the land and building or otherwise entitled to dispose of it in rem (e.g. heritable building rights or tenants with the owner's declaration of consent),
• the entire precipitation water accumulating on the unsealed area can percolate on site,
• no soil or groundwater hazards arise as a result of unsealing, and
• the measure is voluntary, i.e. there is no legal obligation to carry it out, such as a requirement in the building permit.
