aALLIANT ENVIRONMENTAL ASSESSMENT WORKSHEET 11 Robinson Sod Farm PAGE25 GHGs emissions for the project are expected to come from: • Fossil fuels and natural gas used to generate electricity used during construction and operation of the project site and to heat residential home and residential water. • Vehicle and air transportation related to project construction and operation • Refrigeration and air conditioning in each residential home • Transport and treatment of solid waste and wastewater GMG emissions from the project are not expected to cause potential significant environmental effects. The project requires this mandatory EAW due to the surpassing the residential development unit threshold. GHG mitigation measures may be incorporated into the project design and may include: • Smart irrigation to reduce outdoor water use • Energy efficient light and building materials to reduce electricity use • Plant no -mow fescue mixed or native prairie/pollinator gardens to decreased mowing and increase carbon sequestration in common areas around residential units. b. Vehicle emissions - Describe the effect of the project's traffic generation on air emissions. Discuss the project's vehicle -related emissions effect on air quality. Identify measures (e.g. traffic operational improvements, diesel idling minimization plan) that will be taken to minimize or mitigate vehicle - related emissions. The proposed residential subdivision will generate a small increase in carbon monoxide levels associated with an increase in residential passenger vehicle trips. The project does not require an indirect source permit. No baseline air quality monitoring or modeling is proposed and no measures to mitigate for the increase in vehicle related emissions are being considered. c. Dust and odors - Describe sources, characteristics, duration, quantities, and intensity of dust and odors generated during project construction and operation. (Fugitive dust may be discussed under item 16a). Discuss the effect of dust and odors in the vicinity of the project including nearby sensitive receptors and quality of life. Identify measures that will be taken to minimize or mitigate the effects of dust and odors. Dust will be generated during the construction process on the site. The contractors will be required to control dust by using watering trucks. The adjacent residential parcels and air park to the south will be the nearest receptors of the dust. Mitigation of the short-term dust and odors impacts will be managed through proper coordination and construction planning.
