Hi,
Is the definition of buildable land under LEED-ND identical to the following statement quoted from http://www.ci.blaine.mn.us/index2col.cfm?id=901246?
"The space remaining on a lot after the minimum setback, drainage provisions, ponding, compensatory storage, soils, open space and other site constraint requirements of this ordinance have been met."

No. Under LEED-ND, "an applicant may exclude additional land not exceeding 15% of the buildable land base defined, provided that the land is protected from residential and nonresidential construction by easement, deed restriction, or other enforceable legal instrument."

For reference, here's the full LEED-ND definition of Buildable Land: "the portion of the site where construction can occur, including land voluntarily set aside and not constructed upon. When used in density calculations, buildable land excludes public rights-of-way and land excluded from development by codified law or LEED for Neighborhood Development prerequisites. An applicant may exclude additional land not exceeding 15% of the buildable land base defined above, provided the following conditions are present:
c. The land is protected from residential and nonresidential construction by easement, deed restriction, or other enforceable legal instrument.
AND
d. Either 25% or more of the boundary of each contiguous parcel proposed for exclusion borders a water body or areas outside the project boundary that are protected by codified law; or ownership of, or management authority over, the exclusion area is transferred to a public entity."

Abril and Eliot,
Thank you for the information.
Is it correct to say that building-to-land ratio and buildable land are the same before the exclusions?
In Japan, the building-to-land ratio may change depending on the fire-proofing of the building in certain areas. Would it be wise to count the worst number (smaller buildable land) in this case?
Thanks in advance.

Noriko, the definition of "buildable land" is given earlier in this string. The term "building-to-land ratio" isn't used in ND, but maybe you mean "floor area ratio," which is non-residential building floor area divided by non-residential building land area. Can you clarify your question in relation to SLLc6?

Hi Eliot,
Thank you for the additional information. This question is not specifically related to SLLc6. Sorry for posting it here.
We were interpreting the definition of "buildable land" as applied to all single sites inside the neighborhood and not the the whole ND project as a site. If my understanding is correct now, the "buildable land" is not affected by the regional regulations that define the maximum built area of each single site.
The "floor area ratio" term is used in Japan as well (for both residential and non-residential uses).

You're correct, Noriko. The 'buildable land' calculation is done for the entire project site, not individual building sites within the project.
