SS p1 Construction Activity
Pollution Prevention

  Prevent soil from geo-thermal well
digging on south side flowing into
storm sewers

• • • •


SS c1 Site Selection
  Reduces impact from location of building


SS c2 Development Density &
Community Connectivity

  Opt 1 - Is a previously
developed site but not
60,000 sf per acre

  Opt 2 - Is a previously
developed site but not 10
units per acre or enough
Basic Services within ½
mile

  Square is 1 mile per side


SS c3 Brownfield
Redevelopment

  Site isn’t documented as
contaminated by federal,
state, local or voluntary
program


SS c4.1 Alternative Transportation –
Public Transportation Access

  No bus stops within ¼
mile

  Picture is ½ mile per side
  The Middleton Ave. is so
wide because it used to
have a streetcar line down
the middle of it.


Bicycle Storage and Changing Rooms

  2 FTE (Full Time
Equivalent) Occupants

  Not a commercial or
institutional building
requiring racks for 5% of
peak users and showers
for 0.5% FTE

  For residential – One
covered bike storage
meets requirements for
15% of occupants


Low-Emission & Fuel-Efficient Vehicles


  Opt 1 provide vehicle of at
least a Green Score of 40
(3% of occupants)

  Opt 2 provide preferred
parking for one Green
Score of 40 vehicle (5% of
total parking of 2)

for electric vehicle (3% of
total parking capacity


Parking Capacity

code and preferred
parking for one place (5%
total)

  Opt 2 Non-Res - parking
for one place (5% total)

excluding building
footprint

zoning requirement by
25% with vegetated
open space

  Opt 2 If no zoning
requirements - Provide
vegetated open space
equal to footprint

SS c6.1 Stormwater Design–
Quantity Control

  Opt 1 – Existing
imperviousness is less
than or equal 50% (one-
year, 24-hour design
storm – about 2.75” for
Maryland). 1” of rain
would require 890 gal.
storage for the 1500 sf
roof. Install 8 rain barrels.

imperviousness greater
than 50%, volume
stormwater runoff by 25%
(two-year, 24-hour design
storm – about 3.5” for

demonstrate that the site
can absorb 1” of rainfall.
The site can but the roof’s
900 gallons need to be
treated.

need to increase to 400
gallons

site has shade (paver drive
doesn’t count because it
isn’t at least 50%pervious)

parking spaces are under
cover (None are)


SS c7.1 Heat Island Effect –
Roof

SRI is 70. Would need to
paint it with a 78 SRI
material.

green roof trays for ballast
and paint 765 sf with SRI
material 78.

  The Solar Heat Gain
Coefficient (SHGC)
measures how well a
window blocks heat
from sunlight. The
SHGC is the fraction
of the heat from the
sun that enters
through a window.
  The Boulter House
SHGC is expressed project can’t
as a number comply with this
