I’ve been looking at LEED for Neighborhood Development (LEED-ND) in some detail lately, as evidenced by posts examining the system’s fees and also my first experience planning the certification process. While I’m starting to get a feel for the system, my efforts pale in comparison to the work of Brendon Slotterback over at NetDensity.net:
Areas Meeting LEED ND Minimum Eligibility Requirements in the Twin Cities
Brendon’s apparently excellent GIS mapping skills allowed him to progressively eliminate areas ineligible for LEED certification due to non-compliance with various Smart Location and Linkages category prerequisites, and the result is the chart above of eligible areas across the entire Minneapolis/St. Paul metropolitan area. You can read all of the four part series by clicking the links below or through this summary page on his website.
Part 1: Includes a brief overview of LEED-ND and the HUD decision to begin scoring grant, and then creates a map excluding all areas in the region that do not meet wetland/floodplain avoidance, agricultural conservation, and endangered species habitat protection requirements (i.e. examines compliance with SLLp2-SLLp5).
Part 2: Focuses almost exclusively on the SLLp1, Smart Location and Linkages prerequisite and its myriad requirements.
Part 3: Examines areas that may technically be eligible for certification but have strong market barriers due to poor connectivity or low density in the surrounding areas.
Part 4: Brings it all together and looks forward to zoning and policy recommendations that would help foster greater adoption of these practices in the future.
Does LEED-ND Get It Right?
I found Brendon’s site via commentary from Kaid Benfield on his own blog over at the NRDC. He was particularly interested in the ability for small towns and rural areas to meet the SLL requirements, and judging by this post he feels that the system works.
These posts led to a lively discussion on a local planning list I subscribe to, where one respondent was upset that a local new urbanist community planned by DPZ, Habersham, would not qualify due to the fact that it’s not an infill project surrounded by dense development. It’s an excellent development internally, not far enough away from the existing town to in my opinion be considered contributing to sprawl, but it is located on a greenfield surrounded by river and marsh on one side and not much other than forests on the other. Our conversation happened to align with a visit from Steve Mouzon, author of The Original Green, who summed up the discussion well:
Currently, LEED-ND is based primarily (but not entirely) on the assumption that most meaningful interactions occur outside your neighborhood. So Pienza would fail. As would Key West. As would any number of New Urbanist places, including Habersham… LEED-ND doesn’t “trust” very much that the developer will, over time, be able to capture very much interaction… LEED-ND doesn’t have very good accounting of time at this time.
It’s clear to me that LEED-ND requires not only good development practices but is also fairly strict about where such development occurs. I see this as a positive but am very interested to hear your thoughts. Should Key West, a town that could literally be wiped off the map if sea level rise predictions come true, be a place that LEED-ND should foster? Should LEED-ND be more forgiving if what’s developed is significant enough to create its own town center, or should we only encourage growth of existing town centers?
