19. In Seattle, severe runoff problems in one neighborhood were solved by creating rain gardens along the length of an entire street. Before construction of the rain gardens, runoff from this street flowed into a local creek. Rain gardens not only absorb runoff but look great.

Editor's Notes
Talking Points This compares the changes in pre- and post-development hydrology. The changes in runoff are very dramatic with at least half headed into the drainage system. PICP mimics pre-development conditions via surface infiltration, water storage in the base and infiltration into the soil subgrade beneath it. This post development graphic indicates the impact of suburban development on a previously forested area.
This is the only slide in this presentation that address’s cost. Cost benefits for Permeable Paving Systems are documented throughout many case studies. This UK EPA document provides a comparison of cost benefits relative to other LID Systems. Note: Water Butt is a Rain Barrel.

The UK EPA promotes SUDS, which is inline with LID techniques here in the US.
This slide provides an overview of Laws that were implemented in Scotland, England and Wales pertaining to new building codes. Essentially SUDS Systems must be incorporated into building practices as a 1 st choice. Watercourses or Sewage systems are only allowed if a document can be provide to support why SUDS can not be applied.
Case study in the Netherlands.
Australia’s version of LID
School applications provide hands-on education of LID techniques for the future generations. A study complete by two seniors will be presented at a Green Building Conference in Buenos Aires this October.
