FAQs about SSc2 :

Is my site previously developed?

What exactly does LEED mean by residential neighborhood or area?

Only a portion of my complying residential development lies within the ½-mile radius. Will this suffice for credit compliance?

Where do I draw the radius from?

Is one building or residential area enough to satisfy the residential density requirement?

My project has access to services that seem to be basic, but are not listed in the LEED Reference Guide—like insurance company, nail salon, auto repair shop. Will these count?

My project is on a base or campus where some services are available to the population of the project, but not the general public. Do these count?

For Option 2, does the residential neighborhood with average density of 10 units per net acre have to be existing, or can planned neighborhoods count towards earning this option?

What site area should be used for an interiors project when figuring out the density radius? The building site area, or building footprint?

CI-2009 SSc2:Development Density and Community Connectivity

Documenting the credit...

I am currently submitting for a LEED CI v3.0 project and need to document the Development Density. I have no issues with Community Connectivity. That being said, how do I find the numbers that are needed to answer the following questions on the LEED Template: Average property density within density boundary (sf/acre) (Note: Must be at least 60,000 to document credit compliance) Density radius (linear feet) A map will visually illustrate that my project easily meets this credit, I just need to find out how to obtain the numbers to complete the template to confirm that I have met the credit. Thanks!

Jennifer- You should be able to find both of these answers in the reference guide. The density radius equation is based off project site area and gives a radius in linear feet... Density Radius (lf) = 3* sqrt{site area(acres)*43560(sf/acre)} Average property density (within that boundary/radius) is determined by summing each property's building area/site area. NYC has an interactive map which makes finding this info veryvery easy (http://gis.nyc.gov/doitt/nycitymap/)... Development Density (sf/acre) = Gross building Area (sf) / Site Area (acres). The documentation toolkit tab here has a step by step guide to creating a density map if that is useful Hopefully that answers it!

Kate, thank you. I understand how to actually calculate all the numbers. The issue I have in Los Angeles, especially in unincorporated cities, is getting access to the surrounding buildings' information. I was wondering if there was a tool I didn't know about like a special feature in google earth that ties into density. It is one of those credits that can be especially easy in the right city, or terribly hard in others based on what information that city has available online. I appreciate the step by step guide to creating a density map though. Very helpful!

Jennifer, Do you think that your project will qualify for the exemplary performance credit? If yes, then keep pursuing the information. If not, document the credit with Community Connectivity and be done. Most of our projects don't qualify for the EP credit so we document this credit via Community Connectivity as a general rule.
