NC-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 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."). In determining how easily your project can comply, site selection is one key factor, but so is the availability of property and building data.

    Two compliance options

    There are two compliance options for this credit. Unless you are in a dense urban neighborhood where either option is possible, your choice will probably be determined by the specifics of your project.

    • Option 1: Development Density requires the density of the community to be 60,000 square feet of floor area per acre or more. This is a typical density for a two-story downtown development.
    • Option 2: Community Connectivity requires connections to neighborhood services as well as to housing with at least 10 units per acre. This option could apply to a variety of settings, from urban areas to rural small towns with a density of services.

    Documentation is key

    Project teams should assess early in the planning stage which path is most suitable based on project location and the availability of density data. The owner, architect or civil engineer often take on the role of documenting this credit—either researching community services in the project’s vicinity, or documenting the density of the project and surrounding area.

    Community Connectivity is generally easier to document than Option 1. Image Courtesy YRG SustainabilityThe size of the area that has to be included in the Option 1 calculation depends on the size of your project site.

    Projects can earn an Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. point through IDc1 if they meet Option 1’s requirements and are themselves twice as dense as the surrounding area, or can show that the surrounding area has double the required Option 1 density over twice the area.

    Eight of the ten services for Option 2 have to be existing and in operation at the time of the project opening. Two services can be anticipated within a year of opening. One service can be within the project itself.

    Differences between NC v2.2 and NC 2009

    The credit requirements for v2.2 and v2009 are exactly the same, However, the specifics of what can qualify as a basic service are further defined and outlined in v2009.

    For v2.2, basic services that are in construction by project completion can contribute to the credit requirements. For v2009, these basic services must be in operation. Additionally, for mixed-use projects, under v2.2 no basic services that are part of your project can contribute to the credit requirements. In v2009, one service can be within the project itself. 

  • FAQs for SSc2

    What exactly does LEED mean by residential neighborhood or area?

    LEED defines residential neighborhood or area as a minimum of 10 living units (i.e. an apartment unit or house) per acre. Apartment buildings, neighborhoods, or dormitories can all contribute to this.

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

    It can be easier to earn this credit in a dense urban environment, but an average two story downtown can also comply. Photo – YRG SustainabilityIn LEEDuser's experience, if a residential development of 10 units/acre lies within a portion of the ½-mile radius, it likely will contribute to credit compliance. This is consistent with LEED Reference Guide guidance that states, "Mark all residential developments within the radius. For the project to earn this credit, a residential area with a minimum density of 10 units per acre must be present within the radius."

    Where do I draw the radius from?

    Use the center of the LEED project boundary.

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

    Yes, LEED user’s experts have had success with documenting a single property that is at least 10 units/net acre density. Any discrete area that addresses the requirements is acceptable, and an existing residential area meeting the requirements may cross property lines between different properties. For projects with residential areas that are on the cusp (or perceived as being on the cusp) of meeting the required density, you may need to provide additional documentation or an explanation as to how the residential area meets at least 10 units/net acre. Finally, it is not sufficient for the area to be zoned to the correct density, if it is not built to it.

    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?

    Probably not. Project teams need to be careful when trying to pass off services not explicitly given in the LEED credit language. In most cases services not listed will not be approved. Review the credit intent and think about whether the additional services—in the absence of other basic services—are pedestrian-oriented and encourage walkable neighborhoods. However, some projects have had success in specific cases, such as a hotel being considered as a basic service for an office space with frequent contractors visiting. A CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide is probably needed to get approval for special cases like this.

    Also, to reduce confusion during a review while maintaining honesty, be careful to label your services to be consistent with the credit language list. For example, a "nail/hair salon/barber shop" should be categorized as a "beauty salon." If a gas station contains a full-service, stand-alone convenience grocery store (e.g. 7-Eleven) and credit is sought for grocery store use, label it as "convenience grocery" rather than a "gas station."

    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?

    Maybe. Language in the Reference Guide is not crystal clear on this point, and some comments from project teams indicate that campus projects should demonstrate that services are open to the public. For LEED documentation purposes, LEEDuser recommends avoiding relying on such services, or seeing a CIR to be sure of your approach.

    LEEDuser has seen reports of review comments questioning the inclusion of services on a military base or other installation that are not open to the general public, even if they are open to anyone within the radius. On the other hand, one project team reported success with a military base where access to the base was restricted to the public, and services on the base were open to anyone on the base.

    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?

    The SSc2 Option 2 residential requirements for NCv2.2 and NC 2009 are for projects to locate in an area within one-half mile of an existing, not planned, residential district featuring a density of at least 10 units/acre. Projects should not depend upon planned residential areas for credit compliance, as this does not represent existing infrastructure in most cases. Projects not meeting these requirements but believing they meet the credit intent will be considered on a case-by-case basis and must submit a project-specific CIR to determine their compliance potential.

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

    All projects use the building site area for the density radius calculation.

    Is my site previously developed?

    Many projects have had questions about the definition of previously developed. Note that LEED 2009 projects have had the relevant definition updated by USGBC through a November 2011 addendum. Be sure to reference that definition, which is more specific, if it is applicable to your project.

  • Is your site “previously developed”? This credit is available only for projects on previously developed sites—those that have been graded or modified by human activity. 


  • Determine early on which of the two compliance paths is most feasible for your project. This will be determined by your project location. For projects that have the choice, Option 2 may be easier to document, although both options require developing a site plan and documenting the existing conditions of the surrounding area.

    • Option 1: Development Density is for project sites with a density of more than 60,000 square feet of built floor area per acre of land.
    • Option 2: Community Connectivity is for projects within a half-mile of a residential zone with an average density of 10 units per acre. 

  • It can be easier to earn this credit in a dense urban environment, but an average two-story downtown can also comply. Photo – YRG SustainabilityTypically, the requisite neighborhood density for Option 1 of 60,000 ft2 per acre can be met by two-story downtown development, or a denser area. The requirements for Option 2 can typically be met in a variety of settings, from dense urban areas to rural small towns with some density of services.


  • You can earn an Exemplary Performance point through this credit, but only through Option 1: Development Density. If you have some choice of which option to pursue, and the extra point is important, go for Option 1.


  • Weigh the pros and cons of locating a project in a dense urban area, as there may be trade-offs involved. For example, air quality and open space are two variables that could be compromised by locating a project in a dense urban area. However, LEED is generally oriented toward rewarding projects that locate in urban areas, particularly through SSc4.1 and other SS credits.


  • Careful site selection is crucial for obtaining this credit. Projects located in dense urban areas will qualify more easily, whereas projects located in rural or suburban areas, where densities are lower and development more spread out, may find this credit unattainable. 


  • Option 1: Development Density


  • Calculate the average neighborhood “built” density, with a target of 60,000 ft2 per acre, minimum, including your project building as well as surrounding buildings. Undeveloped public areas—including parks, water bodies, and public roadways—are not included in density calculations. 


  • All occupied buildings must be counted in the development density calculations. This would generally include conditioned spaces intended for occupancy, with an FTE above zero. Typical excluded spaces might be:

    • parking garages;
    • smoking pavilions;
    • and maintenance sheds not intended as workspaces. 

  • This approach is much easier to document if density information is accessible via a database of the built densities of all buildings in a neighborhood. Without such a resource, it can be hard to locate this information, and Option 2 may be preferable from a documentation standpoint. Obtaining this data can be a challenge if municipalities don’t provide a centralized database of building and property information for existing building stock—including lot area, building area, and number of residential units. Check with your local planning department or the regional, county, or state planning office GIS database. 


  • Locating your project next to a water body or park shouldn’t affect your density calculations, as undeveloped public areas, including parks and water bodies, are not factored into density calculations. 


  • Many urban sites are previously developed and may be brownfields. Investigate and address any contamination and remediation issues early in the planning process.  Doing so can contribute to earning SSc3


  • There may be a fee associated with obtaining data from a public agency’s GIS database. 


  • Option 2: Community Connectivity


  • Demonstrate that there is both:

    1. Pedestrian access to common services. Examples of basic services include: bank, church, school, grocery, laundry facilities, doctor’s office, and a post office. (See the list of common acceptable basic services in the credit language.)
    2. Proximity to a residential area within a one-half mile radius. The residential area must have an average density of 10 units per acre.

  • If a service is considered basic but not included in the list, attach a narrative explaining why you think this is acceptable or consult with GBCI. 


  • The one-half mile radius is drawn from the main building entrance. 


  • Documenting this option is easier than documenting Option 1, as there is little data collection involved, and usually no calculations to perform (unless there is no other documentation available and you have to calculate the housing density to make sure it is at least 10 units per acre). 


  • There may be costs associated with developing a site in an urban setting (due to aspects such as site constraints and brownfield remediation), although there can also be savings due to reduced need to install infrastructure.


  • Building within an existing urban fabric adds significant benefits for users, including lower transportation costs and healthier lifestyle. Employers may find that this helps attract and retain personnel.


  • To check your project’s eligibility to pursue this option, draw a circle with a one-half-mile radius centered on your project’s main entrance. If there is a qualifying residential development, and at least ten basic services, within the circle, your project is eligible to pursue this path. 


  • There must be pedestrian access to the basic services. Pedestrians cannot be blocked by walls, highways or other permanent barriers. 


  • To find the density of residential buildings near your project, check with sources like planning departments, or property management companies on a building by building basis. 


  • For mixed-use projects, one service located within the project boundary may be counted towards the credit calculation, and that service must be accessible to the general public. For example, if your project is an office complex with a coffee shop and dry cleaners—and they are accessible to the general public—one of these two can count as one of the ten required basic services.


  • At least eight of the ten required services must be operational at the time of project completion. For services that are nonexistent but proposed (up to two of the ten required services), the project team must demonstrate that they will be up and running within one year of occupancy. This can be documented by signed lease agreements or a letter from the developer or owner stating the scheduled opening of the service 


  • Access to services can attract more building occupants and improve occupant satisfaction with any project type—resulting in better financials and productivity. 

Schematic Design

Expand All

  • Complete density or community connectivity calculations relevant to Options 1 or 2 below.


  • These tasks could be completed in schematic design, design development or at 100% CDs. What is critical is to have the project square footage and site area set prior to performing final calculations. 


  • Option 1: Development Density


  • Your project area must be defined consistently throughout all LEED credits (per the project description). Make sure this is the case, especially if your project is part of a larger development, such as a campus. 


  • Check that your project can comply, using these three steps:

    1. Divide the total project square footage by the total site area in acres. (The minimum density required by this credit is 60,000 ft2 per acre). 
    2. Convert the total site area in acres to square feet (acres X 43,560 square feet) and find the square root of this number. Then multiply the result by 3 to determine the appropriate density radius in feet. Density Radius = 3 x √ [site area in acres x 43,560 ft2/acre].
    3. Define a circle based on the density radius to serve as the density boundary. Add the square footage of all buildings within the boundary and divide by the total area of all sites in the density boundary in acres. Include both the entire floor area and entire site area for all properties within and intersected by the density boundary (i.e., where the radius boundary intersects a building, even if only partially). Be sure to include your project site as well. Parks and water bodies can be excluded from the density boundary area. 

  • The calculator within LEED Online computes the density radius as well as the average density by summing up the building square footages and the site areas in acres. 


  • Confirm that the average density of your project is at least 60,000 ft2 per acre.


  • Per CIR 9/22/06, you can document Exemplary Performance as part of IDc1 through Option 1: Development Density using one of the following methods: 

    1. Document that your project has twice the density of the average surrounding neighborhood within the established density boundary area. 
    2. Demonstrate that the average density in an area twice as large as the density boundary is at least 120,000 ft2 per acre. Establish the expanded density boundary by doubling the size of your site area and redoing the square root calculation. 

  • Option 2: Community Connectivity


  • Use online mapping resources such as Google Earth to draw a one-half mile radius from the project building entrance. Your project must be within one-half mile of a residential development with a density of at least ten units per acre, net, as well as within one-half mile of ten basic services. 


  • For projects with more than one main entrance or more than one building, you may draw a circle from more than one entrance. The area contained within the circles drawn from all these radii is then used as your project’s radius.


  • Identify at least one residential development that meets the requirement within the defined boundary. (This could be one apartment building containing ten units.)


  • If you determine that your project is eligible for this credit option, develop a list of all the services within that half-mile radius (or several half-mile radii), and their distance from the project site. 


  • All the services must be accessible by foot via an uninterrupted, safe path stretching from the designated entrance to the service location. The path cannot cross a highway, for example, unless there is a pedestrian pathway. 


  • For onsite services or those within a half-mile, you can count up to two restaurants in the list of ten community services, but no other service can be counted twice. For example, if there are three restaurants, two hair salons, and four dry cleaners within your radius, you can count two restaurants, one salon and one dry cleaner. 


  • If any of the ten services are nonexistent but planned, you must obtain written documentation that these services will be operational by the time the occupants move into your building. Appropriate documentation includes a lease agreement or a letter from the owner or other responsible party. Only two unbuilt but planned services can be counted in your credit documentation.


  • Websites like Walkscore and Google Maps can provide locations of services and walking access from a given address. (See Resources.) Note, however, that resources like these contain limitations that may not match up with LEED requirements (Walkscore, for example, assumes that you can walk across water, if that's the most direct route.) Use them as a starting point to identify services and approximate distances, but be sure to make adjustments as needed.

Design Development

Expand All

  • Check that no changes are made to the design that might hurt your chances of earning the credit.


  • If your project site is located in a dense urban area where pollution is a concern, design your building to minimize potential air quality problems. Place outdoor air intakes away from sources of pollution as much as possible. Consider acoustics and other issues that might be associated with urban environments.

Construction Documents

Expand All

  • Complete the LEED Online credit form and prepare the following documents to show credit compliance, according to your chosen option. The LEED Reference Guide also offers good process guidance and sample documentation for this credit. 


  • For both options, a licensed professional (PE, RA, or RLA) can sign off on the credit in lieu of entering all the calculations. The professional whose license is on the line will likely want to confirm all the calculations anyway, and the credit form offers a good way to do that.


  • Option 1: Development Density


  • Provide a site-vicinity map, to scale, showing the project site and the one-half mile boundary from the project’s main entrance. Highlight the residential development and ten services within the boundary. 




  • Compile a list of all buildings that are within or are intersected by your density boundary, with square footages and site areas for each property. Highlight the results of your calculations and confirm that your project meets the credit requirement. 


  • Option 2: Community Connectivity


  • Provide a site-vicinity map, to scale, showing the project site and the one-half mile boundary from the project’s main entrance. Highlight the residential development and ten services within the boundary. 




  • Demonstrate through an online tool, picture, or site plan that ten services are accessible by foot from the project site. 


  • Compile a list of services for easy review, and confirm that the credit requirement is met.

    5 Points

    Intent

    To channel development to urban areas with existing infrastructure, protect greenfields and preserve habitat and natural resources.

    Requirements

    Option 1: Development density

    Construct or renovate a building on 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 in a community with a minimum density of 60,000 square feet per acre net (13,800 square meters per hectare net). The density calculation is based on a typical two-story downtown development and must include the area of the project being built.

    OR

    Option 2: Community connectivity

    Construct or renovate a building on a site that meets the following criteria:

    • Is located on a previously developed site
    • Is within 1/2 mile of a residential area or neighborhood with an average density of 10 units per acre net
    • Is within 1/2 mile of at least 10 basic services
    • Has pedestrian access between the building and the services

    For mixed-use projects, no more than 1 service within the project boundary may be counted as 1 of the 10 basic services, provided it is open to the public. No more than 2 of the 10 services required may be anticipated (i.e. at least 8 must be existing and operational). In addition, the anticipated services must demonstrate that they will be operational in the locations indicated within 1 year of occupation of the applicant project. Examples of basic services include the following:

    • Bank
    • Place of Worship
    • Convenience Grocery
    • Day Care Center
    • Cleaners
    • Fire Station
    • Beauty Salon
    • Hardware
    • Laundry
    • Library
    • Medical or Dental Office
    • Senior Care Facility
    • Park
    • Pharmacy
    • Post Office
    • Restaurant
    • School
    • Supermarket
    • Theater
    • Community Center
    • Fitness Center
    • Museum

    Proximity is determined by drawing a 1/2-mile radius around a main building entrance on a site map and counting the services within that radius.

    Potential Technologies & Strategies

    During the site selection process, give preference to urban sites with pedestrian access to a variety of services.

     

Web Tools

Google Maps

For locating community services on a map in relation to project site.


NYC online map portal

For building information in the City of New York; useful for calculating density and identifying residential developments. 


Google Earth

Great resource for creating site maps and measuring distances.


Walk score

This online tools provides “as-the-crow-flies” distance to typical standard services from a given address, so it is most helpful to identify the location of basic services that are in close proximity, but shouldn’t be used to document walking distances. 

Community Services

Option 2: Community Connectivity

Compile a list of qualifying community services and residential neighborhoods, and their proximity to your project using a template like this one (with example shown).

Community Connectivity Narrative

Option 2: Community Connectivity

Use a narrative like the one illustrated in this example to demonstrate compliance with this option. This sample narrative provides sample language for planned community services, in addition to existing ones.

Design Submittal

PencilDocumentation for this credit can be part of a Design Phase submittal.

Development Density Calculations

Option 1: Development Density

Calculations like these are needed to demonstrate the required development density for your site.

Planned Community Services

Option 2: Community Connectivity

Use a narrative like this to discuss use of services that are planned but not built to meet Option 2. As many as two of 10 services may be planned.

1) yes- it's listed right in the rating system
2) No - restaurants are the only basic service you're allowed to list more than once; you can have up to two restaurants

Previously developed site definition

The project we are working on is to be built on a land that has been graded as it is part of a national master plan that defines the plot ratio and creates the buildable plots in advance. However, there has never been any structure built there before.
It seems that, from previous comments, previous grading of the site makes it '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."', but in the definition of your website it is written that sites with previous clearing and filling are not considered as previously developed.
Which case are we in, and how confident can we be that this site is considered 'previously developed'?
Thanks!

Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agrigultural 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.

You raise a good point, the original definition of previously developed specifically included sites that were graded but the above definition seems to reverse this when it says land that is altered by current or historical clearing or filling is considered undeveloped land.

Has anyone else dealt with or been affected by this new definition?

Thanks Ellen,

Just to add to the previous comment, I wonder what happens in the context of urban planning for which a state has authority. In our case, in Singapore, all the plots are part of a Master plan, controlled by state authorities. The site is graded by them, and the plot ratio and usage for the site (Industrial in this case) are pre-determined. Does it mean that basically none of the projects in this situation can be considered as '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."', or all of them?
Thanks.

In my opinion, I would interpret this with some reference to time. If the grading, etc., occurred years in the past, in anticipation of development, it seems to meet the new definition of 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.". If done recently with the relevant project being considered, it feels like the definition does not apply.

Tristan, can you please explain further why you think that the "reference to time" matters to site classification?
My interpretation to 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." definition is that a site that had a permit issuance to some alterations that were actually done («altered by paving, construction, and/or land use that would typically have required regulatory permitting») can be considered as previously development regardless of the «alterations may exist now or in the past». It is the date of the permit issuance that should be used («The date of previous development permit issuance constitutes the date of previous development») but it's the actual alterations that qualify the site for this classification («but permit issuance in itself does not constitute previous development»).
Am I interpreting this right?

Pedro, since this is a hypothetical example, it would help to have some specifics to understand better. It's easy to get tied up in confusing knots with hypotheticals.

My reference to time is inexact, I admit. But I'm trying to use it as a proxy for LEED project scope, even if work on the site is done by a different entity. I would contend that is a site that is graded and then developed is not 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.", no matter who does the grading. But if it was graded years ago, that simply seems different.

Tristan, I'm aware of the issues that can be raised by hypothetical assumptions, however, I believe my previous comment didn't have any "hypotheticals". I just tried to present my interpretation of the definition applied to this case in particular and was hoping that from here on, others could contribute with their view and actual experience. This is mainly because I don't feel very confident regarding the interpretation of previous developed definition when it comes to sites that don't have construction but had infrastructural alterations prior to acquisition. In that cases I don't understand why time of alteration matters...

There is a thread about this in the CS forum for SSc2 (dated 12/11/12), although there was not a clear consensus. I would say that it depends on what the basement is used for and if it is included in your overall square footage calculations that you based your GBCI review fees on.

I would think a reasonable approach is to exclude any square footage that is parking since you would exclude that portion of the building when registering with GBCI (price is based on square footage but excludes parking structures).

The Reference Guide says "a residential area with a minimum density of 10 units per acre must be present within the (1/2 mi.) radius (502.4 acres)." Is there a minimum percentage of the area within the circle that must average the 10 units/acre?

Susan Di Giulio Project Manager, Zinner Consultants Mar 18 2013 LEEDuser Member 434 Thumbs Up

On our project, we have the latest v4 formand it asks for the:
"Development density of the surrounding residential zone or neighborhood."
It sounds very much like they are asking for the entire residential area within the 1/2 mile radius of the site to be 10 units per acre or more. In fact, we probably have that, but it is going to be really difficult to document: this is a dense historic neighborhood with a mix of 1, 2 and 3 family bungalows on each 5000 SF lot. And there are several hundred lots. The only way I know of to document the density is to look up each lot on the county assessor's web site and there are well over a hundred lots. Aiiiiiiiiiiiiiiiii!
Can I do a representative sample and extrapolate? How big do you think it would need to be?

Ellen Mitchell Sustainable Design Coordinator, HKS, Inc. Mar 19 2013 LEEDuser Expert 831 Thumbs Up

For the development density option, you will need to document the density of all of the properties within the density radius to make sure that the average is greater than 60k sf. However, your radius is not necessarily a half mile. The example section in the reference manual will give you the formula for determining the radius and will walk you through the calculations. Just a note for clarification though, the community connectivity option for this credit only asks to you identify a single residential area with a density of 10 units/acre net and does not expect you to document the densities of all the buildings in your half mile radius.Obviously that is the easier option if you can come up with the 10 basic services.

Thanks, I didn't state it clearly but we are going for the connectivity option, and the wording of the v4 template is to provide "Development density of the surrounding residential zone or neighborhood" in units per acre, right above the field for listing services. This would constitute a major change in the requirements for the credit, but if that's not what they meant, why word it that way?

I will not even try to reason why it is worded that way and agree that it is confusing. I have submitted this form with only inputing in the denisty of a single apartment building or complex (as well as identifying it on my map) and had it pass successfully so I don't think it is meant to be a change in the requirements.

I read 'development density' and think 'zoning'. Luckily, some counties align the residential zoning with the units per acre allowed - for example R-10 means residential, 10 units per acre. Others are more obtuse, as is their way.

Now if you aren't zoned to the required level, you may need to prove actual density to the reviewers.

Kristina Bach CORE Steward, Cooper Carry Mar 19 2013 Guest 96 Thumbs Up

Careful - 'Zoning' does not equal 'Existing Density' in LEED's eyes. Typically, it seems like projects will be kicked back as pending when they try to provide just the local zoning regulations as that isn't really proof that the existing area actually meets LEED's minimum level of 10 units/acre (perhaps the zoning was just increased/changed, perhaps other types of development have gone in that have actually decreased that existing density level to below the zoned amount, etc). You need to make sure that you demonstrate that the existing actual density is at least 10 units/acre. Ellen's method of demonstrating the existing density of at least one apartment building/complex is probably the most common for urban projects.

Do transit bays count in property calculation

I have a project that sits atop a subway station and across the street from a major local bus transfer facility, which consists of a lot of open space with bus queing lanes and passenger loading bays. Although the roads surrounding this are clearly public right-of-ways to be excluded from the density calculations, the actual bus lanes/bays were built by the county on land that is technically still platted in the property records. Including this as property SF will obviously skew the density calculations negatively (there are no structures other than passenger shelters), though I would propose that this land is equivalent to the public right-of-ways where other buses pull over off the street (this occurs literally adjcent to the platted land as part of the transit center). Has anyone encountered a similar situation?

One question - are you trying to submit the three buildings as a single LEED project? Even though GBCI released the Multiple Building Campus Guide in 2011 and stated that LEED online would support a multiple building application beginning the first quarter of 2012, that capability is still not available. Until it is, I believe that you will need to register all three of these projects separately even though you can set up a master project which allows you to have the documentation of some site credits applied to all three buildings. In this case the half mile radius will be different for each project site.

1/2 mile distance to basic services..

Our project is located within 1/2 mile radius of more than 10 basic services. There is pedestrian access between the building and the services. Will it be accepted if the pedestrian routes/sidewalks (within the 1/2-mile radius) to the 10 services is longer than 1/2 mile?
Is the 1/2 mile- requirement also a requirement for walking-distance?

Hope you understand my question,

1/2 a Mile walkable distance evidence/survey

Hi Everyone,

A little bit of an obscure question in regards to community connectivity. I was wondering if anyone knew how USGBC chose 1/2 mile to be considered a walkable distance. I cannot find any referenced studies or surveys.

If anyone could link me to a study providing evidence for this credit or a similar 'walkable distance' study, that would be great.

It seems an often quoted distance that likely has the same root source. Tax information is interesting. From the DC WMATA website:

"Increases Property Value Around Transit: An analysis of parcel-level property tax assessments for all properties within a half-mile of Metrorail stations shows:

$235 billion of property value is within a half-mile of Metrorail stations.
This land generates $3.1 billion annually in property tax revenues.
This land represents 28% of the jurisdictions’ property tax base, but only 4% of their land.
Proximity to Metrorail increases property values by 7-9%."

NC Comercial Building into a LEED ND Neighborhood (Stage 1)

Our project is located into a LEED Neighborhood Development which obtained Stage 1 certification. The Neighborhood Project is going to be developed in phases and this building is the first of 26 buildings to be built.

The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development." site?

Question 2: Since the NC is going to be located into a LEED ND (Stage 1 Certified), the whole Certification process is the same that would be held if the project was located somewhere else? Does it exist a simplification or a credit heritage for those credits which have been involved in the ND Certification (for example SSc4)?

In regards to the NC certification within an ND framework, I'm not sure how to advise. The approach you are describing is similar to what block projects can do, but I don't know if it is allowed for ND as well. This question may be better posted on the ND forum where people may have more experience with that rating system.

Dear Ellen,

I thought that there were water & electricity pipings running across the site, but I have realized they are not.
So, our site has never had buildings before. Nevertheless, since it is located on a LEED ND, it is surrounded by 4 streets (one of them already existed and the other 3 where built by the ND owner).

New Shopping Centres & Basic Services

After reading all the “shopping centre” related posts under the NC, C&S and CI rating systems forums, I still can’t confirm the following:

- for a new shopping building, undergoing a LEED NC or LEED C&S certification, can I count the basic services that the shopping itself will have at the moment of its inauguration (moment in time were the building is certified)
OR
- does this situation fall in the option referred in the Ref. Guide that states that the project building itself cannot be considered 1 of the 10 basic services; however in a mixed-use building, a maximum of 1 service within the building may be counted as 1 of the 10.

Does anyone have any previous experience in complying with this credit under option 2 with new shopping buildings?

Thanks.

David Posada Sustainability Manager, GBD Architects Sep 07 2012 LEEDuser Expert 11323 Thumbs Up

Normally, I think you'd only be able to count 1 of the services in the new shopping center, since this credit is intended to reward projects that are being built around existing dense development and services.

There is an option in the reference guide that allows 2 future, anticipated services to be counted if 8 are are ready open.

If you are in an area that already has a high density of development, but not the 10 services, you could try submitting as an "alternate compliance path," but you wouldn't want to assume you'd earn the credit. You could also submit a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide if you need to get a more definite answer.

Minimum Density Calculation

In the Sustainable Sites CREDIT 2/ OPTION 1 – Development Density - I don’t understand why “the density calculation is based on a typical two-storey downtown development…” Why not on a 1-storey or 3-storey or more?
If in that area, there are some other buildings with more than or less than two storey, how do we calculate? How about in a ten-storey (or 15, 20 or 25 -storey or only 1-storey) downtown development, will the minimum density be changed or not?
Could you help me explain this item more clearly to my students?

Cat,
A typical 2 story downtown development has an approximate density of 60,000 sf/acre. It is only used as a way to provide an example of scale as to the minimum density a project would need to meet the credit requirements. The minimum density requirement of 60,000 sf/acre does not change based on project conditions.

Multiple types of medical office

My review team said that four of my ten basic services were medical offices and that I could only count that service once. However, the purposes of these facilities are very different: lab testing, mental health, sports medicine, wellness classes. They don't duplicate any services. What's the rationale behind not allowing each of them to count? Do I have any recourse here? I have other services to use instead, but I'm irritated that these clearly unique services can't be counted individually.

Maura, as you can see from past discussions on this forum, and the FAQs above, LEED is fairly strict about the letter of requirements here. You are probably stuck with the review standing as is. I definitely sympathize with your pont, in defense of the review requirement I would say that these facilities are similar enough that it could be argued there is not enough diversity in the 10 services you are listing, and that is one of the purposes of the list of 10.

John, if there is no safe way for pedestrians to access these services, then the credit is not achievable. Safe is the key word here. A suburban site without sidewalks, crosswalks, etc. does not seem to meet the intent of the credit, even if there are sufficient services within the 1/2 mile radius.

What about non-contiguous sidewalks? ie If a sidewalk becomes part of a parking lot then back to sidewalk (or some variation) The reference guide clearly states "pedestrians must be able to walk to the services without being blocked by walls, highways, or other barriers." It seems that a parking lot would not qualify as a 'barrier' since it is common for people to walk thru parking lots.

Also, how is the sidewalk requirement documented in the form? It seems that this documentation requirement should be added in 2012. (if not planned already)

Thanks

Tony, it is common for a sidewalk to cross a parking lot outlet and for pedestrians to be able to cross that safely—particularly if there is a crosswalk painted. I would look for curb cuts, crosswalks, signage, and other indicators that a parking lot really is walkable, and that this isn't just wishful thinking.

As for how this is documented, not all credit requirements are documented in the LEED Online forms. That's true for many credits. I understand that in LEED 2012 USGBC is working to have more consistency with that kind of thing.

Sidewalks and all-weather access

I currently have a project on a military base that was denied this point because "not all of the listed services have sidewalk pedestrian access from the project site....dirt trails do not meet the credit intent of contiguous pedestrian access. All pedestrian access must be located along pedestrian-oriented infrastructure (sidewalks and crosswalks) so that ADA and all-weather access is guaranteed for all building occupants"

I've never encountered a problem like this on other military projects for this credit. The LEED Ref. Guide v. 2009 mentions that "pedestrians must be able to walk to the services without being blocked by walls, highways, or other barriers", but I don't understand why they would think a "dirt trail", which is actually more like a dirt sidewalk (if you've been on military bases), is a barrier.

Anyone ever deal with something similar? Or have any ideas of a suitable way to appeal this?

Alberto, sorry for the slow response here to your question—have you made any progress on this, or decided on a path (pun intended)?

If I were you, I would appeal this with reference to the language and the fact that an explicit requirement for ADA-compliant sidewalks is not stated. You could submit photographic evidence that the pathways in question are commonly used by all kinds of folks.

In the end, though, you might not earn the credit—hopefully it's not crucial for the project.

Community Connectivity - Campus Services

In the review process for our project. We have received teh following comment:
"It is unclear whether all of the community services are available to the general public. Note that it is the intent of this credit that basic services are available to everyone, and are not restricted to campus occupants and staff."

We have claimed certain services, like the student health center, which to me provides a "BASIC SERVICE" however based on this review team's interpretation I guess we can't count it. Has anyone else run into this problem? There is absolutely NO text in the rating system guide that says "basic services must be available to everyone" My argument is that these services are eligible to everyone within a 1/2 mile radius because it covers the entire campus. Any advice?

Thanks in advance.

Shannon., I've had the exact same comment come up on college projects and on military installations. To me, the review comments are unreasonable, because it seems as if the definition of "gen public" should be within the context of the facility. However, I wasn't able to get these items resolved to my satisfaction when I was working on those projects.

Shannon and Edgar,

The key sentence in the credit requirments is "For mixed-use projects, no more than 1 service within the project boundary may be counted as 1 of the 10 basic services, provided it is open to the public." This indicates, albeit not very explicitly, that all services must be open to the public to qualify.

I appreciate you guys posting these experiences here. I'm documenting university campus projects as well, and have been trying to steer clear of univ. buildings to satisfy the requirements. The point about the military base is very well put and I'd like to see a clarification come out in an addendum. University campuses are less clear, but in both cases campus facitlities are open to students, employees, staff and spouses. They provide a basic service thousands or tens of thousands in their surrounding community need, which includes access for the users of your project. If the service was there but excluded the users of your project or the majority of the surrounding community I would support the reviewer.
In the case of the health center, check and see if memberships are available to the general public or if it is only for employees & students. Perhaps they offer kids or community classes.

Super 8 Motel - comply with 10 units per acre

Can a super 8 motel be used as a residence documenting 10 units per acre if the operator is leasing rooms on month to month basis?

I really doubt it but double check the zoning.

SSCr2 - Option 2 LEED Review

Just received comments back from GBCI regarding our SS credit 2. I'm a little confused because when reading bullet point 2 of the reference guide under option 2 (page 23), it says the following:

* is within 1/2 mile of a residential area or neighborhood with an average density of 10 units per acre.

When reading the above "or" means one or the other??

Meaning, our project must be within 1/2 mile of a residential area?

If anyone could add further clarification to my understanding, it would be appreciated?

Tom

I interpreted this credit the same way as you did. Average density is 6 units. acre around our project site, but it is within 1/2 mile. We believe to qualify for this credit. What was the actual comment from USGBC?

This is what our LEED reviewing team said:

The LEED Credit Form has been provided stating that the project site is located within one half mile of a minimum of ten community services and an existing residential district with a minimum density of ten units per acre. Additionally, a listing of the neighborhood services has been provided on the form. The site vicinity map has been provided showing the one half mile radius, the locations of the community services, and the existing residential districts.

However, the residential districts appear to be comprised primarily of single-family housing, and their actual densities have not been indicated to demonstrate that these areas have a density of at least ten units per acre.

If you look at the credit form and the reference guide, "and" is not stated. It says "or"...

In my opinion, changes the requirement that is to be submitted?
