Ms.Allen October 24,2005 PA-0500699(GP) Page 3 The District encourages innovation in measures to reduce air quality impacts. There are a number of features that could be incorporated into the design/operation of this project to provide additional reductions of the overall level of emissions. (Note: Some of the measures may already exist as (City)(County) development standards. Any measure selected should be implemented to the fullest extent possible.) The suggestions listed below should not be considered all-inclusive and remain options that the agency with the land-use authority should consider for incorporation into the project. • Trees should be carefully selected and located to protect the building from energy consuming environmental conditions, and to shade paved areas. Trees should be selected to shade paved areas that will shade 50% of the area within 15 years. Also, large canopy shade trees should be planted adjacent to all sidewalks thirty foot on center and at a ratio of one tree for each five parking spaces. Structural soil should be used under paved areas to improve tree growth. For more information on structural soil see htti)://www.hort.cornell.edu/uhi/outreach/csc/. For more information on tree selection see http://www.ufei.org/. For more information on urban forestry see http://www.coolcommunities.org, http://wcufre.ucdavis.edu and http7//www.loc.org/bookstore/energv/downloads/s'v tree guidelines pdf. • Sidewalks and bikeways should be installed throughout as much of the project as possible and should be connected to any nearby existing and planned open space areas, parks, schools, residential areas, commercial areas, etc.,to encourage walking and bicycling. Sidewalks and bikeways should be designed to separate pedestrian and bicycle pathways from vehicle paths. Sidewalks and bikeways should be designed to be accommodating and appropriately sized for anticipated future pedestrian and bicycle use. Such pathways should be easy to navigate, designed to facilitate pedestrian movement through the project, and create a safe environment for all potential users (pedestrian, bicycle and disabled) from obstacles and automobiles. Pedestrian walkways should be created to connect all buildings throughout the project. The walkways should create a safe and inviting walking environment for people wishing to walk from one building to another. Mid-block paths should be installed to facilitate pedestrian movement through long blocks (over 500' in length) and cul-de-sacs. Clearly marked and highly visible pedestrian accesses create a safer environment for both pedestrians and vehicles. Pathways through the project should be built in anticipation of future growth/development. • As many energy conserving and emission reducing features as possible should be included in the project. Energy conservation measures include both energy conservation through design and operational energy conservation. Examples include (but are not limited to): - Increased energy efficiency (above California Title 24 Requirements) See http://www.energy.ca.gov/title24/. - Energy efficient widows (double pane and/or Low-E) - Use Low and No-VOC coatings and paints. See South Coast's site for No-VOC Coatings at http://www.aqmd.gov/prdas/brochures/paintguide.html - High-albedo (reflecting)roofing material. See htto://eetd.lbi.gov/coolroof/ - Cool Paving. "Heat islands"created by this and similar projects contribute to the reduced air quality in the valley by heating ozone precursors. See http•//www.harc.edu/harc/Proiects/Cool Houston/ and http://eande.lbi.gov/heatisland/ - Radiant heat barrier. See hftp://www.eere.enemy.gov/consumerinfo/refbriefs/bc7.html - Energy efficient lighting, appliances, heating and cooling systems. See http://www.enemystar.goy/ - Clean alternative energy features to promote energy self-sufficiency. Examples include (but are not limited to): photovoltaic cells, solar thermal electricity systems, solar water-heating systems, small wind turbines, etc. Rebate and incentive programs are offered for alternative energy equipment. More information can found at http://www.dsireusa.org/, http://rredc.nrel.gov/, and htto://www.energy.ca.gov/renewables/ - Programmable thermostat(s)for all heating and cooling systems - Awnings or other shading mechanism for windows - Porch, patio and walkway overhangs - Ceiling fans - Utilize passive solar cooling and heating designs. (e.g. natural convection, thermal flywheels) See http://www.eere.energy-gov/RE/solar passive html - Utilize daylighting (natural lighting) systems such as skylights, light shelves, interior transom windows etc. See http7//www.advancedbuildings.org
