It’ll never work here It ll never work here. Heavy clay soils, flat land, intense Heavy clay soils, flat land, intense
rain events and too much annual rainfall.

Gaps that Needed to be FilledGaps that Needed to be Filled
Gaps between disciplines– Use of integrated design teams limited
Gaps in educationGaps in education– Focus on our soils, climate, topography
Focus on ‘nuts & bolts’ Focus on nuts & bolts – Practical application rather than the theoretical
Individual constituent groups limited– Inherent tendency toward narrow focus

Low Impact Development (LID)Low Impact Development (LID)
• Decentralized water managementDecentralized water management– Micro scale controls– 180° shift from centralized approach180 shift from centralized approach
• Toolbox that provides opportunities to make a developed property function hydrologically like developed property function hydrologically like an undeveloped property
Mimic nat re to achie e ater management goals– Mimic nature to achieve water management goals

Why a Design Competition?Why a Design Competition?
• Resolve the ‘chicken or the egg’ syndromegg y– How comfortable are you with proposing new
methodology if you’ve never used it?
• Prevent more ‘missed opportunities’ on LEED® project sitesp j– Sustainable elements in Green Buildings are
often all inside the building envelopeg p

What We Wanted To AccomplishWhat We Wanted To Accomplish
• Integrated design teams• Key to genuinely sustainable design
• Real properties with challenging conditionsp p g g– Enable knowledge transfer, viable LID adaptations
• Runoff reduction and attenuation• Post-construction hydrograph must be below pre-
developed condition for 5, 10 and 100 year events
• Cost comparison of LID to Traditional design– Is better and cheaper possible?

Notable CommentsNotable Comments
‘I was one of the finalist judges down there, and it j granks among the most exhilarating experiences of my 31-year career at EPA.... The most exciting part was that so many people involved had no background in LID prior and came out the other end believers and even proselytizers. Truly remarkable.’ ― Dov Weitman, Chief, Nonpoint Source Control Branch, EPA
LessonsLessons
• LID is a superior design approach even when Water Quality is a secondary goal
• Regulatory pressure isn’t needed to make LID g y pthe dominant method of development
• The opportunity to learn for yourself is criticalThe opportunity to learn for yourself is critical• Sustainable design thrives in a collaborative
approach in designapproach in design
Implementation Interest Soars Implementation Interest Soars
How do we facilitate LID moving into the Market?
Expediting LID DevelopmentPermitting is Biggest Concern
• Collaborative LID Permitting Design Criteria Collaborative LID Permitting Design Criteria Workshops in June, July, August
Involved City and County staff design – Involved City and County staff, design community and developers (75)
– Objective is to get LID projects on the ground Objective is to get LID projects on the ground today without new code for now
– ‘Interim’ LID Design Guide developed from the Interim LID Design Guide developed from the results
