STEP Life Cycle Costing Tool (Ontario)

The Sustainable Technologies Evaluation Program have produced a life cycle costing tool specific to Ontario. STEP built the tool after evaluating LIDA stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting. practices and design scenarios for input costs, maintenance requirements, rehabilitation costs and practice designs relevant to Canadian climates. The tool is in a simple to use Excel format and is free to download. STEP tool

Green Infrastructure Optimization Tool (Great Lakes)

The Greater Lakes Green Infrastructure Optimization Tool gives a preliminary assessment of green infrastructureNatural vegetation and vegetative technologies in urban settings such as: urban forests; green roofs; green walls; green spaces; rain gardens; bioswales; community gardens; natural and engineered wetlands and stormwater management ponds; and porous pavement systems. These systems are designed to provide multiple benefits, such as moderate temperatures, clean air and water, and improve aesthetics. options. Land-cover types (and technologies) include: Existing and proposed buildings, existing and proposed paved parking areas, walkways and roadways, open space, pasture, meadow, brush, woodland/grassland, woods and bare soil.

Green Values Stormwater Toolbox (Great lakes, USA)

A free tool for evaluating the costs and benefits of green infrastructureNatural vegetation and vegetative technologies in urban settings such as: urban forests; green roofs; green walls; green spaces; rain gardens; bioswales; community gardens; natural and engineered wetlands and stormwater management ponds; and porous pavement systems. These systems are designed to provide multiple benefits, such as moderate temperatures, clean air and water, and improve aesthetics.. It is based on the hydrology of the Great Lakes region, and produced by the Center for Neighborhood Technologies, a non-profit organisation in the USA.

United States EnvironmentRefers to the conditions in which an organism lives and survives or the conditions in which an organism resides. These conditions can be described as aspects of a “physical”, “social” or an “economic” environment, depending on the perspective perceived by the observer. Protection Agency (USA general)

CIRIA's BeST tool (UK)

A tool which monetizes EcosystemA biological community, including humans and their natural environment. Services (ESS) and Triple Bottom Line (TBL) criteria to assess LIDA stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting. options (described as Sustainable Drainage Systems, SuDS). The tool guides the user to consider some or all of the co-benefits listed below . Whilst the relative values may be useful for assessing options, the currency of this model is in GBP (£).
