change "For each transit stop, count the number of times a bus, train, or ferry stops per day;" to "For each transit stop, count the number of times a bus, train, or ferry stops per day. If the number of rides varies over the year (e.g., the project is in an academic campus or a seasonal resort), the average rides per weekday should be used."

change "Count all transit stops that are within 1/2 mile of the home. " to "Count all transit stops that are within 1/2 mile of the home. Multiple transit stops can only be counted if they are for different transit lines. For example, a single bus that stops just north of the home, in front of the home, and just south of the home, should only be counted as one stop. Stops for the same line that travel in different directions (e.g., an inbound bus and an outbound bus) count as different stops."

Replace the table with two tables as indicated in the supplemental documentation. (Note that this table was updated again on February 2, 2011)

[Add new paragraph to beginning of Calculations section] "The distance requirements must be calculated based on possible walking distances, not "as the crow flies". For example, if a resource is within 1/2 mile on a map, but requires >1/2 mile of walking because of highways or other obstructions, the resource should not be counted.

"This credit cannot be earned through the use of private wells or septic systems" change to "This credit is not automatically earned through the use of private wells or septic systems. Projects with private wells or septic systems can earn this credit, but the home must be located within 1/2 mile of central water and sewer service lines; the home does not need to be connected to the central water and sewer service.

[Add new paragraph after 1st paragraph ending "...as an infill site"] "For LL 3.3, estimate the percentage of the total site that is previously developed. If the home is located in a new development, then the development site includes all of the new home sites in that new development, not just the one building site that is to be certified."

In the second row ("Typical new gray concrete"), replace the SRI of 35 with 38

Replace the text in item A of the legend with "< 15% Slope = up to 100% Develop"

[Add new paragraph to beginning of Calculations section] "A guidance document and accompanying calculator have been developed for performing the calculation for this credit. Please contact your LEED for Homes Provider for these resources."

In this section, replace all instances of "USGBC" with "GBCI"
