Estimates of the life cycle costs of inspection and maintenance have been produced using the latest version of the [[Cost analysis resources|LID Life Cycle Costing Tool]] (LCCT) to assist stormwater infrastructure planners, designers and asset managers with planning and preparing budgets. <br>

Estimates of the life cycle costs of inspection and maintenance have been produced using the latest version of the [[Cost analysis resources|LID Life Cycle Costing Tool]] (LCCT) to assist stormwater infrastructure planners, designers and asset managers with planning and preparing budgets. <br>

For [[vegetated filter strips]] and [[soil amendment areas]], life cycle cost estimates have been calculated for two level-of-service scenarios: the minimum recommended frequency of inspection and maintenance tasks , and a high frequency scenario to provide an indication of the potential range. The LCCT has assumptions for  [[vegetated filter strips]] and [[soil amendment areas]] based on an impervious to pervious area (I:P) ratio of 2.5:1 and inspection and maintenance recommendations for enhanced swales, for relevant components.
