SS: Sustainable Sites

Question 1

SS Prereq: construction Activity Pollution Prevention

What is an Erosion and Sedimentation control plan and what strategies does it promote

Answer 1

• ESC Plan must comply with EPA guidelines 2012
• Erosion and sedimentation control (natural buffers sediment track out minimization, sediment discharge control, preserving top soil, minimize disturbance of steep slopes, protecting storm drain inlets)
• Stabilization (seeding, mulching, dikes, terracing, silt fence)
• Pollution prevention (prohibited discharges, pollution prevention, emergency spill notification, fertilizer discharge restrictions)

Question 2

SS Prereq: Environmental Site Assessment (schools and healthcare only)

Answer 2

Start with phase 1 environmental site assessment (ESA) to determine whether contamination is suspected

Phase II ESA will confirm if contamination - needs remediation

Remediation can include
-pump and treat, solar detoxification, bioreacotrs, etc.

Question 3

SS Credit: Site Assessment

What are the elements of a site assessment

when should it be done

Answer 3

• Topography
• Hydrology
• Climate
• Vegetation
• Soils
• Human Use
• Human health effects

Do the site assessment prior to design to identify possible opportunities

Question 4

SS: Site development - {rptect or Restore Habitat

how much of site should be preserved and protected

Answer 4

• 40% of greenfield site condition should be protected from developmenta nd construction
• Additional 30% of land including building footprint can be restored (or financial support can be provided)

Question 5

Ss: Site development - protect or restore habitat

Explain “on-site restoration” and when can a greenroof be used

Answer 5

30% of land (including bldg footprint) should be restored using native or adapted vegetation.

• Projects that have a density of 1.5FAR may include vegetated roof as part of 30%
• Vegetated landscape areas constructed to accommodate rainwater infiltration can be excluded

Question 6

SS: Site development protect or restore habitat

Explain financial support

Answer 6

If projects don’t want to restore additional 30% they can provide financial support of $0.40/sqft for total site area (including bldg footprint)

Question 7

SS: Open Space

What are the % requirements

Answer 7

Provide outdoor space greater than or equal to 30% of total site area

A minimum of 25% of outdoor space must be vegetated or have overhead vegetated canopy

Question 8

SS: Open Space

What characteristics must the open space have

Answer 8

One or more of the following:

• Pedestrian-oriented paving or turf to accommodate outdoor social activities
• Recreation-oriented paving or turf to encourage physical activity
• Garden space with diversity of vegetation types and species
• Garden space dedicated to urban food
• Preserved or created habitat that meets SS Credit Protect or restore habitat

Question 9

SS: Open Space

What must a project have in order to count vegetated roof towards % of vegetated outdoor space

Answer 9

Achieve density of 1.5FAR

Question 10

SS: Rainwater Management

What are the three paths you can take for Option 1: Percentile of Rainfall Events

Answer 10

Path 1: 95th Percentile
-Manage on site the runoff from the developed site for the 95th percentile of regional or local rainfall events using “low-impact development” and “green infrastructure”

Path 2: 98th Percentile (3pts)

Path 3: Zero Lot line only -
- For urban projects with a minimum density of FAR manage only for 85th percentile

Question 11

SS: Rainwater Management

Explain Option 2: Natural Land Cover Conditions

Answer 11

Manage on site the annual increase in runoff volume from the natural land cover condition to the post-developed condition

Question 12

SS: Heat Island Reduction

Explain Option 1: Non-roof and roof (including equation)

Answer 12

Project teams use a combination of strategies to reduce heat islands.

Uses surface area of compliant strategies
-Area of non-roof measures,, area of high-reflectance roof, and area of vegetated roof.

(Area of non-roof measures/0.5)+(Area of high reflectance roof/0.75)+(Area of vegetated roof/0.75) >= (Total site paving area+Total roof area)

Question 13

SS:Heat Island Reduction

What are non-roof strategies

Answer 13

-Minimize hardscape
-Use existing plant material or install plants that provide shade over paving areas
-Provide shade with structures covered by energy generation systems (solar thermal collector, PV, wind turbines)
-Provide shade w vegetated structures
-Use pavign with SR value of at least 0.28 for 3-year and 0.33 if no year is available
Use open grid paving system (at least 50% unbound)

Question 14

SS: Heat Island Reduction

What are Roof Strategies

Answer 14

Use roof materials that have a solar reflective index (sri) equal or greater than 82 for low sloped roof and 39 for steep sloped roof

Question 15

SS: Heat Island Reduction

ExplainOption 2: Parking Under Cover

Answer 15

Place a minimum of 75% of parking spaces under cover (underground, under deck, under building)

Motorcycle parking counts as vehicle parking while bicycles do not

Any roof used to shade must

• have 3 year SRI of at least 32
• Be vegetated roof
• Be covered by energy generation systems

Question 16

SS: Heat Island Reduction

Overall what strategies should you use to minimize heat island

Answer 16

• Minimize development footprint
• Limit the amount of impervious hardscape
• Utilize light-colored paving surfaces
• Include a buidling parking deck or underground parking
• Plant vegetation that will provide shade
• Open grid paving

Question 17

SS: Light Pollution Reduction

What three factors are addressed

Answer 17

Uplighting - full cutoff

Light trespass - BUG

Internally illuminated signs - do not exceed 200cd/m2 during nighttime and 2000cd/m2 during daytime

EXEMPTIONS:
-marker lighting for transportation
-Lighting used solely for facade and landscape lighting in MLO zones 3&4
Theatrical lighting
government mandated roadway lighting
hospital and helipads
flags internally illuminated signage
