Barriers to LID and leed LEED Internet Resource guide 20110303Jon Barsanti
Previous research into sustainable development practices to safeguard water quality have led me to research a presentation on barriers to implementing LID and LEED construction. The bibliography includes hyperlinks to EPA documents, as well as other resources, pertaining to air quality, water quality, conservation subdivisions, LEED, and LID.
LEED, LID, And Policy May 2010 (Handouts)Jon Barsanti
Low Impact Development is moving to the forefront of development procedures. It looks to maintain or improve water quality at the level that was existing prior to development. If water quality and water quantity were improved on all new construction and all new redevelopment projects, then we would see improving water quality across the board. If We only use LID on new constructions we will only be keeping the water quality at the same level as it was predevelopment. LID and LEED can save money in the short-run, long-run, or both.

LID LEED and Policy August 2010 (final) (handouts)Jon Barsanti
A look at what and who is holding back LID and LEED developments. Looks at the returns on investments and the benefits to the ecosystem by changing our thinking towards where and how we develop
LID LEED and Policy Barriers to Implementation December 2010 v3Jon Barsanti
A presentation I made to the NCLID training group. Opening slides referenced some questions raised during class.
* All development occurs in a watershed
* All Land Uses have a water profile
* LID can improve water quality/water quantity
* A paradigm shift is needed with regard to water as a reusable/valuable resource rather than as a discharge.
A paradigm shift is on-going from high impact development to low impact development. There are proponents and opponents to these established building practices.
'Nobody' is asking to prove that conventional development isn't 'bad' for the environment. "Everybody' wants to prove that LEED and LID are 'good' for the environment.
A lot of discussion has revolved around LEED standards for new construction and whether or not LEED has gone far enough to promote indoor air quality. Others are focused on the cost benefits of LEED and LID. LEED does have cost savings and benefits to the builders and the consumers.
A presentation I was asked to make to the LEED, LID, and Policy Seminar Students at NCSU. This focuses on the barriers to LID Implementation and offers some resources.
Enabling communities to regenerate mountain landscapes in the African HighlandsILRI
Presented by Tilahun Amede at the Stakeholders’ Workshop on Enhancing Communities’ Adaptive Capacity to Climate Change Induced Water Scarcity in Kabe Watershed, South Wollo Zone, Wollo University, Dessie, Ethiopia, 24-25 November 2011.
In the Davao Region of Southern Mindanao, Philippines, Integrated Water Resource Management (IWRM) has been a key framework for promoting sustainable land use in local ecosystems. However deteriorating trends continue across the watersheds and there is an absence of critical reviews to validate whether the current set of policies are providing a supportive environment for sustainable socio-ecological production landscapes .
This workshop will present the results of a project conducted by the Council of Great Lakes Industries and funded by the Great Lakes Protection Fund to evaluate the applicability of global water stewardship tools at Great Lakes industrial facilities. Workshop presenters will review the results of pilot tests at four facilities — the Consumers Energy power plant in Grand Haven, Michigan; The Escanaba Paper Co. mill in Escanaba, Michigan; a Shell petroleum refinery in Sarnia, Ontario; and a Lafarge cement plant in Bath, Ontario — and provide an opportunity for participants to discuss water stewardship measures, public disclosure practices, and the potential for identifying water stewardship goals and tracking methodologies.

fish, frogs, wildlife as well." Ryan Winston wetland/bog plants

Barriers to Implementing
LID Across the Region
• Need to look at Decentralized solution for a decentralized
problem
• Our ordinances hold us back (e.g. State law now requires
communities to allow the use of cisterns and to not prohibit
their use; Definitions of Conservation Subdivisions; Transfer
of Development Rights)
• “Everybody knows….”

Maintenance
• Fertilizer
• Animal Waste
• Drought Tolerant Plants
• Native Plants
• Over-watering
Conclusion
We have a new resource
We can ‘sing from the same
songbook.’
We can customize our solutions
to meet the requirements of our
communities and our region.
We can have a Win-Win-Win for
the consumer, the developer,
and the community.
If we ‘only’ apply to new
construction, existing conditions
will ‘only’ not get worse.
