Changes

*Cost estimation for [[dry ponds]] has been added to LID practices. [[SWM ponds|Wet ponds]] are also included as a traditional stormwater management strategy in order to facilitate direct comparisons with LID.

*Refined algorithms to reflect line cost updates and construction practices (i.e., [[Bioretention: Sizing:bioretention sizing]] algorithm based on latest guidance).

*Added a land value option to all BMPs. This allows users to account for land acquisition when required and for opportunity costs when otherwise developable land is used for stormwater management.

*Updated maintenance task schedules using “discretionary maintenance options” and defaults that were based on observations in the field.
