21 LL Credit 5 Community Resources/Transit Community Resources/ Transit Photographer: Jennifer Owens Encourage building of LEED homes in development patterns that allow for walking, biking, or public transit. 1-3 Points

22 LL Credit 5 Community Resources/Transit Select a site that meets one of the criteria below: Resources within ¼ mile Resources within ½ mile Weekday Transit Rides within ½ mile LL 5.1 Basic (1 point) LL 5.2 Extensive (2 points) LL 5.3 Outstanding (3 points)

23 LL Credit 5 Community Resources/Transit Basic Community Resources include: Arts and entertainment center Bank Community or civic center Convenience store Restaurant Fire station Laundry or dry cleaner Up to two of each type of community resource can be counted.. Example: 2 restaurants within ¼ mile = 2 community resources 4 restaurants within ¼ mile = 2 community resources

24 LL Credit 5 Community Resources/Transit Calculate transit rides per weekday : 1. Within ½ mile radius, count all transit stops Transit Rides Calculation 2. Multiply each transit stop by number of buses, trains, and ferries that pass through per day (service frequency) 3. Add total number of rides available at each stop within ½ mile together Example: 4 bus stops + service frequency half-hourly (48 times per day) Total transit rides per day = 192
