Work Products CH2M HILL shall provide the City a noise study technical report up to 30 pages in length, including graphics and appendices. Assumptions • CH2M HILL shall identify the properties for which noise measurements will need to be taken at outdoor activity areas. The City shall contact property owners and obtain permission for CH2M HILL staff to conduct noise measurements on the property. • Up to 3 noise monitoring locations will be included in the noise survey to show existing noise levels in the project vicinity. • Noise levels will be monitored for a period of 20 minutes at each monitoring location. Noise Measurements will be repeated only in those cases where a specific aberration in noise conditions is identified during the monitoring. Field work would be completed in a single one-day trip. • Up to 6 receiver locations will be identified as noise prediction sites to represent full coverage of the study area. • City shall provide the CAD files needed for producing graphics and for calculating the number of impacted receptors, also showing area roads and current and future elevations. • City shall provide profiles, grades, elevations, toe of slope, right of way lines, other engineering data needed to model the noise impacts. • City will provide maps identifying any receptors that will be purchased as part of the project and figures/base maps suitable for documenting land use and zoning in the project area. • City shall provide necessary existing, future build and future no build traffic data including peak hour volume, speed and vehicle mix (autos, medium trucks, heavy trucks and buses) on area roads and I-5 to be used in the FHWA Traffic Noise Model to predict traffic noise exposure. • The scope assumes CH2M HILL will not be attending any meetings associated with the noise component of this project. Budget CH2M HILL proposes to complete this work on a lump sum basis, with a task fee of $13,350 for the scope described above.
