Identified Problems
Need for best practice manual
• LEED-ND does not provide implementation methods
• Testing unproven ideas are costly
Ideas + Testing =
Best Practices Manual (BPM)
• Focus on LEED Neighborhood Pattern and Design (LEED-NPD) category
Worcester Polytechnic Institute

Deliverable
• BPM table
• List of detailed guideline on the 15 NPD credits

DeliverableCredit: Title of LEED Credit
Intent: This section provides the objectives of the credit named above, as provided in LEED-ND handbook.
A. To easily present information on a variety of topics, this section subdivides the credit into smaller goals.
Goal Associated Best Practices
Concerned Agencies
1. This column provides the goal of the subdivision named above. While it may share a common theme with the intent of the entire LEED credit, it focuses more on one aspect of the credit, rather than the whole.
1. This column lists the best practices associated with achieving the goal mentioned in the adjacent left column.
Since achieving many of these goals may require changes to
zoning, streets design, bus routes etc, this column provides the
name of any agencies or bodies that may
need to be involved in the planning process in
an effort to expedite completion of the
project.

Credit 1: WalkabilityIntent: To promote transportation efficiency, including reduced vehicle miles traveled. To promote walking by providing safe, appealing, and comfortable street environments that support public health by reducing pedestrian injuries and encouraging daily physical activity.
A. Alley RevitalizationGoal Associated Best
PracticesConcerned Agencies
1. Reclaim alleys as walking paths for pedestrians, providing alternate routes throughout a city’s center, and promote connectivity.
1. Increase lighting and signage, giving the alleys more of a “street” feeling. 3. Replace asphalt with more pervious materials. 4. Promote alleys as viable space to local businesses, especially for outdoor restaurant seating. 5. Turn alley into park where applicable
