Tampere

Formalized catchment planning. Municipality led model.

0 notes on this case

A dedicated stormwater fee finances retrofit of high-risk catchments. City is taking the lead to implement catchment-fit NBS as part of drainage system. Catchment planning is coordinated by city and NBS solutions are co-created with multiple departments, and maintenance is handled by a separate municipal department.

STRATEGIC GOVERNANCECATCHMENT-FIT NBS DELIVERYADAPTIVE CAPACITYCatchment-fit NBS deployment in Tampere has gradually evolved from individual pilot projects into a mainstream municipal stormwater management approach. Political support has been strengthened through recurring flood risk concerns, ecological protection of urban lakes and streams, and positive public reception of multifunctional blue-green environments. The governance model is strongly municipality-led, with stormwater management integrated into several strategic and operational documents, including the City Strategy, Mayoral Programme, Biodiversity Programme, Stormwater Strategy, and land-use planning procedures. National stormwater requirements and municipal guidance frameworks further support local implementation. Over time, Tampere has institutionalized NBS as a routine component of urban development and climate adaptation policy.
Political support
T — TimeTC — ControlCO — OutputOR — ResourceRP — PreconditionPI — InputITampere applies a municipally coordinated financing model where a dedicated stormwater fee provides long-term funding for both construction and maintenance of NBS. The city primarily finances NBS implementation on public land, while private actors contribute indirectly through stormwater fees and compliance with planning requirements. Funding is not limited to hydraulic performance alone, but also supports biodiversity, recreation, placemaking, and urban liveability objectives. Stable annual investment planning allows NBS implementation to continue systematically across catchments and development projects.
Financing model
T — TimeTC — ControlCO — OutputOR — ResourceRP — PreconditionPI — InputITampere applies catchment-scale stormwater planning supported by city-level hydraulic modelling and flood risk assessments. Catchment planning is commonly outsourced to specialized consultants but coordinated and reviewed by the municipal stormwater management team. The planning process prioritises sub-catchments with chronic flood risk and sensitive receiving waterbodies while integrating NBS into broader land-use and urban development planning. Stormwater plans establish runoff criteria and define the principles for maintaining hydrological status quo in developing areas. Existing natural systems, open ditches, waterways, biodiversity values, and future flood routes are considered as part of the planning process.
Catchment integration
T — TimeTC — ControlCO — OutputOR — ResourceRP — PreconditionPI — InputIDetailed NBS design is outsourced through framework contracts to experienced engineering and landscape design consultancies. Designs are guided by municipal stormwater criteria, catchment planning outputs, and interdisciplinary review processes involving stormwater specialists and experts from multiple municipal departments. Tampere's approach emphasizes multifunctionality: NBS are designed not only for runoff control, but also for biodiversity, urban quality, recreation, and ecological connectivity. Monitoring requirements and maintenance responsibilities are increasingly considered already during the design phase.
Design of NBS
T — TimeTC — ControlCO — OutputOR — ResourceRP — PreconditionPI — InputIConstruction is coordinated by the municipal stormwater management team, which supervises implementation and ensures that catchment-scale objectives are preserved during delivery. Although construction itself is outsourced to contractors, municipal stormwater specialists play a strong role in site supervision and coordination. Over time, Tampere has developed a capable local market of contractors and consultancies familiar with catchment-fit NBS implementation.
Construction of NBS
T — TimeTC — ControlCO — OutputOR — ResourceRP — PreconditionPI — InputINBS are maintained by municipal maintenance departments as part of the public urban infrastructure system. Maintenance activities are coordinated and clustered through GIS-based asset management systems that group similar maintenance tasks across the city. The stormwater fee supports long-term operational capacity, while maintenance routines increasingly recognize the ecological and multifunctional nature of NBS assets.

Monitoring data, flood events, maintenance experiences, and project evaluations are systematically discussed within the municipal stormwater department through regular internal review meetings. Learning is used to improve future planning criteria, technical guidance, maintenance practices, and project coordination. Monitoring has demonstrated that NBS have effectively maintained or reduced runoff loads and pollutant concentrations despite urban development, strengthening political and institutional support for continued implementation.
