CS 2009 SSc2: Development Density and Community Connectivity

  • NC_CS_SSc2_Type3_Density Diagram
  • Easier for dense urban sites

    This credit addresses two basic issues: density of the surrounding neighborhood and occupant access to everyday services. It encourages use of existing infrastructure and tries to reduce environmental impacts of transportation. It’s easier for projects located in a densely built area or with a host of community services nearby.

    This credit is not likely to drive the project location decision, but it does reward projects for locating in developed areas and for choosing infill instead of greenfield sites (you can’t earn the credit on a site that is not previously developedPreviously developed sites are those altered by paving, construction, and/or land use that...

Community Connectivity - residential density

I am working on a project (LEED CS 2.0) that easily meets the services requirement, but I'm having a hard time with the residential density requirement. Looking at my aerial photo shows a neighborhood that is mostly single family homes. There are no apartment complexes that meet the 10 units/acre standard, however, there is a project that is in development and will be 50 units covering only a few acres. Can we use the future development option for residential density?

Hi Mark. A future residential development can count provided that you offer clear documentation that the development doesn't encroach on undeveloped/greenfield areas. More specifically, you'll need to document that the development is on or within previously existing urban infrastructure (i.e. roads, sewers, etc). You'll also need to quantify the proposed future density (as you've helpful done here).

Pedestrian Access by Residential Area

In using Option 2 - Community Connectivity, must the residential area have unimpeded pedestrian access to the project, as well as the project having unimpeded pedestrian access to the 10 basic services?

Karla,

The credit clearly states that there must be pedestrian access to the services, but no mention of the resi area. I would err on the side that access should be unimpeded. If there are multiple routes to a basic service all within the 1/2 mile radius you should be okay in meeting the credit intent, even if one path is impeded.

Previously developed site?

I am working on LEED documentation for a project that meets all the requirements in Option 2 for community connectivity. The site has never had a building on it, however it has been graded, there are utilities running through it and it is in the center of a master-planned university campus with surrounding buildings. Will this qualify as a previously developedPreviously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development." site, and is there separate documentation required to prove this?

Hi Reid,
Yes, it's previously developedPreviously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development.". The C&S Glossary defines "Previously Developed" as sites that "once had buildings, roadways, parking lots, or were graded or otherwise altered by direct human activities." In the past, I've provided an aerial image of the existing site, or a Phase II environmental assessment, to show that the site is previously graded.
