This presentation was part of my senior capstone course, Environmental Impact Assessment. I and four other seniors produced a report and final presentation of our LEED ND analysis of the squalicum lofts development in Bellingham, WA.
2. LEED ND Developed by the U.S. Green Building Council (USGBC), Congress for the New Urbanism (CNU), and Natural Resources Defense Council to create a national standard. LEED for Neighborhood Developments (LEED-ND) emphasizes smart growth aspects of development while still incorporating a selection of the most important green building practices.
3. Smart Growth an initiative that focuses on positive growth solutions which advocates for compact, transit-oriented, walkable, bicycle-friendly mixed use development The LEED for Neighborhood Development Rating System integrates the principles of: - smart growth- urbanism- green building LEED certification provides independent, third-party verification that a development's location and design meet accepted high levels of environmentally responsible, sustainable development.

27. Neighborhood Pattern & Design Community Connectivity Open Community Compact Development Diversity of Uses Walkable Streets Street Network Credits Met: 0 Alternative Credits: 9 Total Credits: 9
28. Neighborhood Pattern & DesignCommunity Connectivity Open Community Prerequisite is met through alternative actions The main street access and the sidewalks within the site is currently planned to be gated to the community along with the emergency access road. In order to meet this prerequisite, all streets and sidewalks that are built as part of the project or serving the project directly would be designated as available for general public use and not gated.
29. Neighborhood Pattern & DesignCommunity Connectivity Compact Development Prerequisite and credit are met through alternative actions Redesign the project to include two additional levels on each of the four buildings The result would be an increase of 191,918 square feet for a project total of 291,378 square feet The floor area ratio would equal 0.87 and the project would earn one point for the credit and meet the prerequisite.
30. Neighborhood Pattern & DesignCommunity Connectivity Diversity of Uses Credit is met through alternative actions A residential component equaling at least 25% of the project’s total building square footage would be achieved in the redesign, as the additional floors in buildings B and C would be dedicated exclusively to residential units. After completing this action the credit will be passed as the current building entrances are within a half mile walking distance of 4 diverse uses including Squalicum Park, Bellingham Technical College Library, Madronia School, and Immanuel Bible Church. Additional points could be earned for this credit if additional diverse uses were added.
32. Neighborhood Pattern & DesignCommunity Connectivity Walkable Streets Credit is met through alternative actions Arrange the buildings so that the site allows for parking to be placed in the rear of the building or create an underground garage for the site parking, leaving the frontages and streetscapes free of surface parking. As the buildings will be redesigned to increase residential density the building height to street width proportions of 1:3 will be met. There are no streets currently bordering the project site or planned adjacent buildings. Redesign the sidewalks throughout the sight to border both sides of the street at a minimum of 4 feet. And provide connections to all footpaths from sidewalks for connectivity to areas surrounding the site.
33. Neighborhood Pattern & DesignCommunity Connectivity Street Network Credit is met through alternative actions The street grid density of the 7.56 acre site is approximately 49.1centerline miles per square mile, meeting the standard for street grid density. However, his credit is not met currently due to the emergency access road being gated and closed to public access. This credit could be met if the current emergency access road is opened to traffic, auto and bike. The topography of the site does not allow for any other street connections to the adjoining neighborhood.
35. Neighborhood Pattern & Design Socioeconomic Diversity Diversity of Housing Types Affordable Rental Housing Affordable For-Sale Housing Credits Met: 0 Alternative Credits: 5 Total Credits: 5
36. Neighborhood Pattern & DesignSocioeconomic Diversity Diversity of Housing Types Credit is met through alternative actions The development would be rezoned to include residential units in Buildings B and C in the levels added in the redesign. Four different housing types could possibly be represented in the units. 94 new residential units could be built in this space at an average of 23.5 units for each dwelling type, earning a score of 0.53 on the Simpson Diversity Index, indicating a moderate diversity of housing types within the development.
37. Neighborhood Pattern & DesignSocioeconomic Diversity Affordable Rental Housing Credit is met through alternative actions About half of the 94 residential units in the development’s redesign would be rental properties. The median income in Bellingham, WA for 2009 is $64400. 15% of the rental units would be priced for households with an income of up to 50% of $64400, and 15% of the rental units would be priced for households with an income of up to 80% of $64400.

39. Neighborhood Pattern & DesignSocioeconomic Diversity Affordable For-Sale Housing Credit is met through alternative actions 10% of the for-sale units would be priced for households with an income of up to 80% of the median income, and 10% of the for-sale units would be priced for households with an income of up to 120% of the median income. Affordable housing is defined by the Area Median Income (AMI) Standard as 30% or less of a household’s monthly income being spent on housing costs. For 10% of the units, monthly housing costs could not exceed $1288, and for another 10% of the units, monthly housing costs could not exceed $1932. Additionally, the mortgages on the specified units would need to be such that households at 80% and 120% of the median income could be eligible for them.
41. Neighborhood Pattern & DesignTransportation Reduced Parking Footprint Credit is met through alternative actions The sites surface parking facilities are within the 20% development footprint maximum requirement and the site plans show that118bicycle parking spots will be installed. However, all the non-residential buildings within the project locate their off-street parking along the frontages of Buildings A and B. Building A has a majority of the parking to the side between the building and the street, thus not meeting the streetscape and building frontage requirements. The alternative would arrange the buildings so that the site allows for parking to be placed in the rear of the building or create an underground garage for the site parking, leaving the frontages and streetscapes free of surface parking.
45. Neighborhood Pattern & Design Site Accessibility Access to Surrounding Vicinity Access to Public Spaces Access to Active Public Spaces Universal Accessibility Credits Met: 1 Alternative Credits: 2 Total Credits: 3
46. Neighborhood Pattern & DesignSite Accessibility Access to Surrounding Vicinity Credit is met through alternative actions The access road that runs along the east side of the site is gated and does not allow open access Removing the gate would allow for a through street from Squalicum Parkway to Lafayette Street The west side of the property is exempt from this requirement due to the extreme topography
47. Neighborhood Pattern & Design Site Accessibility Access to Public Spaces Credit is met through alternative actions There are small green spaces on the east side of each building but none of them are 150 feet wide, and do not equal ½ acre. Use space behind Building A as a green space measuring at least 150 feet wide and equaling at least 1/6 acre. In order to meet the required sum of ½ acre, additional green space would be added on the west side of Building C. The above changes coupled with the existing green spaces would meet the ½ acre requirement.
48.
49. Neighborhood Pattern & Design Local Food Production Credit is met through alternative actions Develop regulations that prevent the ban of food production on the site. Purchase shares in a CSA program for at least 80% of the households on the site for at least two years. Choose from the many CSA programs in Whatcom County by inhabitants’ vote.
50. Neighborhood Pattern & DesignUnachievable Credits Community Outreach and Involvement Does not meet the requirement to receive this credit, nor are there any applicable alternatives given that community involvement must occur in the pre-design phase. Universal Accessibility Does not meet the requirement due to inability to meet the requirements for separate kinds of residences (err this is awkward)

56. Green Construction & TechnologyMinimization of Pollution and Site Disturbance Heat Island Reduction Credit is met through alternative actions The site has plans to use pervious pavement, but not the required 50% The project could meet this credit by following these actions: Use pervious pavement to cover at least 50% of the projects impervious areas Using trees for shade or reluctant pavement may be a better option if more cost-effective
57. Green Construction & TechnologyMinimization of Pollution and Site Disturbance Light Pollution Reduction Credit met through alternative actions Reduce the luminance to a value lower than 0.20 footcandles at the sites boundary, and 0.01 15 feet beyond the site No more than 5% of the fixtures should emit light at an angle of 90 degrees or higher.
58. Green Construction & Technology Energy Efficiency LEED Certified Green Buildings Energy Efficiency in Buildings District Heating & Cooling Infrastructure Energy Efficiency Credits Met: 3 Alternative Credits: 3 Total Credits: 6
59. Green Construction & TechnologyEnergy Efficiency LEED Certified Green Buildings Credit met through current actions This project is planned for four LEED silver structures.
60. Green Construction & TechnologyEnergy Efficiency Energy Efficiency in Buildings Confusing Credit met through alternative action To earn one point under this credit the project would need 90% of buildings to show a 10% improvement in the proposed building performance rating compared to the baseline building performance rating Must follow ASHRA/IESNA guidelines
61. Green Construction & TechnologyEnergy Efficiency District Heating and Cooling Credit met through alternative actions Include a district heating system for all buildings, such that 80% of the project's total square footage is connected and 80% of the project total peak heating load is connected If the project does not already include a district heating system the viability of installing a district heating system would need to be assessed
62. Green Construction & TechnologyEnergy Efficiency Infrastructure Energy Efficiency Credit met through alternative actions Meeting this credit requires a large investment by the developer. If the budget is large enough this credit could plausibly be met The project could meet this credit if infrastructure such as traffic lights, street lights, water and wastewater pumps and treatment systems achieve a 15% annual energy reduction from an estimated baseline
63. Green Construction & Technology Water Management Reduced Water Use Stormwater Management Wastewater Management Credits Met: 0 Alternative Credits: 9 Total Credits: 9
64. Green Construction & TechnologyWater Management Reduced Water Use Credit met through alternative actions 90% of all buildings need to be built so that indoor water use is reduced by 30%. This can be accomplished by using efficient fixtures: urinals, lavatory faucets, showers, and kitchen faucets Install landscaping that doesn’t require irrigation
65. Green Construction & TechnologyWater Management Stormwater Management This seems super confusing Credit met through alternative actions Although the site has a progressive and well-developed stormwater management system planned, it is based on capture of storm water and energy/temperature dampening, with the intent of mitigating the impacts of stormwater released into the bay. LEED-ND GCT Credit 9 is rated on how much rainfall re-enters ground stock, so Squalicum’sstormwater management plan is not necessarily creditable under LEED. Adding green roofs, more permeable pavements, rain gardens, would allow maximum point reward of 5 to be awarded, based on a successful capture and infiltration of 2.25" of rain.
66. Green Construction & TechnologyWater Management Wastewater Management Credit met through alternative actions Greywater recycling systems would allow for the project to capture and reuse a high portion of water, and reduce the amount of potable water used for non-human consumptive purposes. The addition of greywater recapture and infiltration into rain gardens would also help satisfy the requirements of GCT Credit 9: Stormwater Management
67. Green Construction & Technology Waste and Recycling Management Recycled Content for Infrastructure Construction Waste Management Comprehensive Waste Management Credits Met: 0 Alternative Credits: 3 Total Credits: 3
68. Green Construction & TechnologyWaste and Recycling Management Recycled Content for Infrastructure Credit met through alternative actions Design project such that the aggregate base and subbase are at least 90% recycled aggregate materials Any asphalt base is at least 15% recycled content Any asphalt concrete pavement is at least 15% recycled asphalt pavement Any Portland cement concrete pavement and any piping made from Portland cement concrete needs to contain at least 25% recycled mineral admixtures and 10% reclaimed concrete material aggregate
69. Green Construction & TechnologyWaste and Recycling Management Construction Waste Management Credit met through alternative actions Garco Building Systems would need to develop a construction waste management plan Recycle at least 50% of the excess steel used in the manufacturing process
70. Green Construction & TechnologyWaste and Recycling Management Comprehensive Waste Management Credit met through alternative actions Add any 2 of the following 3 services household hazardous materials pickup, composting, and separated recycling Recycling is likely to be included, although composting is not likely, as the current site usage is slated for commercial and light industrial works. Household hazardous materials include substances such as bleach and other cleaning supplies, making pickup service a valuable portion of the credit, even if recycling and compost have already been added
