threatened or endangered that are known to live in Montezuma County. However, a November 10,2006, field survey did not identify any of the listed species. Impacts to the Threatened and Endangered Species are estimated to be minimal. Federally listed species do not occupy any habitat zones in the proposed project area. Impacts to local vegetation will be significant to dryland grasses and shmbs within the private easements during constmction. These impacts will be reduced through the use of stmctural mitigation measures that include routing construction away from sensitive critical habitats and limiting constmction during critical plant growth periods. Water Quality Issues There is no surface water within the proposed project area. Water quality issues are limited to those involving runoff and erosion during constmction. These nonpoint pollution issues associated with constmction are best mitigated through the implementation of BMPs including the use of silt fences, water bars, and avoiding constmction during excessive storm events. A storm water management plan will also be on file with the contractor to describe all BMPs, which will be used during the proposed project and non-storm water discharge management. Air Quality and Noise The proposed project will include the use of heavy machinery during constmction which will impact air quality and noise in the area. Impacts during constmction will include dust, diesel emissions from equipment, and noise from equipment. To mitigate the generation of dust during constmction the sites will be watered and chemically stabilized as necessary to prevent excessive dust. Dusty material will be covered in transit when necessaty to prevent blowing. Noise will be mitigated by limiting constmction activities to normal day light working hours only. Equipment will also be equipped with noise control equipment. C Growth Areas and Population Trends The current population in the Goodman Point area is approximately 74 residents who occupy 29 homes in the area. There are currently 25 homes in the area which will receive water service through the proposed project, and 5 property owners with undeveloped property which will receive water service. There are approximately 2.54 persons per home and according to the Region 9 Economic Development District of Southwest Colorado Inc., the rate of growth in Montezuma County is expected to rise and then decrease over the next twenty years. It is assumed that the growth rate in Goodman Point will be similar to that in the county as a whole. The following table and figure show the projected growth rate of Montezuma County as presented by Region 9. Goodman Point Water Association - Preliminaty Engineering RepOli 4
