Ms.Kuhl December 5,2005 PA-0400667(MS) 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 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: • Trees should be carefully selected and located to protect the buildings 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. Structural soil should be used under paved areas to improve tree growth. For structural soil see http://www.hort.cornell.edu/uhi/outreach/csc/. For tree selection see htti)://www.ufei.org/. For urban forestry see http://www.coolcommunities.org, http://wcufre.ucdavis.edu and htti)://www.lgc.orq/bookstore/energy/downloads/sjv treeguidelines.pdf. • 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). For more information see http://www.energy.ca.gov/title24/ - Energy efficient widows (double pane and/or Low-E), lighting, appliances, heating and cooling systems. For further information see http://www.energystar.gov/ - Use Low and No-VOC coatings and paints. See South Coast's site for No-VOC Coatings at http://www.agmd.gov/prdas/brochures/i)aintguide.html - High-albedo (reflecting) roofing material. For more information see http://eetd.lbl.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. For more information see http://eande.lbl.gov/heatisland/http://www.harc.edu/harc/Projects/Cool Houston/ - Radiant heat barrier. Please see http://www.eere.energy.gov/consumerinfo/refbriefs/bc7.htmI - The project should include as many clean alternative energy features as possible to promote energy self-sufficiency. Examples include (but are not limited to): photovoltaic cells, solar water-heating systems, solar thermal electricity 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 http://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, whole house 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 http://www.advancedbuildings.org - Natural gas lines (if available to this area) and electrical outlets in backyard or patio areas to encourage the use of gas and/or electric barbecues - Electrical outlets around the exterior of the unit(s) to encourage use of electric landscape maintenance equipment - Pre-wire the unit(s)with high speed modem connections/DSL and extra phone lines - Exits to adjoining streets should be designed to reduce time to re-enter traffic from the project site • Construction activity mitigation measures include: - Install sandbags or other erosion control measures to prevent silt runoff to public roadways from sites with a slope greater than one percent - Limit area subject to excavation, grading, and other construction activity at any one time - Limit the hours of operation of heavy duty equipment and/or the amount of equipment in use
