Construction Impacts. Reducing Noise and Earth Moving Impacts - Construction activities will temporarily affect the surrounding landscape and vegetation. Development of the rail line may cause temporary disturbance and potential dispersal of Sage-grouse due to noise, human presence, and vibration. The Project is dedicated to reducing the impacts to Sage-grouse mortality or injury as much as possible. While the vegetation can be restored after the conclusion of the construction, sagebrush takes years to re-establish itself, prolonging these temporary impacts. The Project accordingly will take measures to reduce temporary construction-related noise and physical encounters with grouse, including:
Construction Impacts. H-10/ Item 1 “North of the Site: In Phase I, construction of the two Pilot Plants* on the NW corner of the site would generate noise exceeding the Berkeley Community Noise Standards which would be heard in offices along Xxxxxx Way between the Southern Pacific tracks and Fifth St.” 5G-6 H-11/Item 2 “West of the Site—Demolition: Demolition of buildings 2, 3, 4, 6, 7, 12, 14, and 16 would exceed background noise heard in picnic areas of Aquatic Park by 3 dBA or more for one to two months.” 5G-7 H-11/Item 3 “West of the Site—Construction: Construction of the Pilot Plant buildings on the NW corner and the production building on the SW corner of the site would generate noise which would be heard in Aquatic Park for two to three months for each block, with peak construction noise exceeding background noise levels by 3 dBA or more.” 5G-7-8 Same as above.

Construction Impacts. The Project will be under construction over a ten to fifteen year period or longer; thus, construction impacts, including environmental effects and economic and social effects (such as disruption of business, noise, dust) will be an ongoing topic to be addressed.

Construction Impacts. The discussion of construction impacts is based on conceptual plans for construction staging and construction duration. Generally, the construction times referenced are at the 90‐percent confidence level. The exact construction methods cannot be ensured because contractors have a degree of latitude in construction methods and scheduling within the contract specifications and the conditions of approval of the project. For both alternatives, the following construction impact now differs from what appeared in the Draft EIS: Pier 48, Periscope Viewpoint and Alaska Square: The AWV Project includes building a temporary over‐water bridge between Pier 48 and Xxxxxx Dock (this area is between X. Xxxxxxxxxx Street and Yesler Way). The Xxxxxx Dock Ferry Terminal access bridge would be needed for either alternative during construction to maintain access and egress for ferry operations. Once AWV construction is completed, this over‐water bridge would be removed.
Construction Impacts. The general type and nature of any construction related to the proposed action and potential environmental impacts associated with the proposed action will be described. These would typically include noise and air pollution from dust, water pollution from erosion, as well as wetland and floodplain fill and transportation access. Measures to minimize these impacts will be identified.
Construction Impacts. This chapter discusses anticipated changes and disruptions that could affect social resources during construction. Generally, these effects are evaluated for all social resources located within approximately two blocks of the project corridor. This area would be most adversely affected by construction impacts, particularly noise effects. These effects on social resources are temporary, though the anticipated duration of construction for the project alternatives would be many years. A major change has occurred in the approach to construction activities since the publication of the Draft EIS in March 2004. Originally, the construction plan required continued use of the Alaskan Way Viaduct between S. Spokane Street and the Battery Street Tunnel during construction with only very short periods of road closure for one or both directions of travel. This is referred to as the longer plan. Since the publication of the Draft EIS, the engineering approach to the construction of the Tunnel Alternative was modified in an effort to shorten the overall construction period. The revised plans assume that one or both directions of traffic would be closed, either periodically or fully. The shorter plan reduces the construction period for the Tunnel (Preferred) Alternative to 7 years, and the intermediate plan would take approximately 8 to 8.75 years. In contrast, the longer plan to construct the Elevated Structure Alternative would take an estimated 10 years irrespective of differences in constructing the Reconfigured or Relocated Whatcom Railyard. All of these construction periods include the estimated 30 months needed for utility relocations at the beginning of construction activities. The different construction plans also affect how long construction traffic detours would be used. Depending on the construction plan, detours could include the First Avenue S. Detour, Broad Street Detour, and/or general increased use of downtown streets that parallel the Alaskan Way Viaduct, i.e., First, Second, Fourth, and Fifth Avenues. Traffic also would use I‐5 to avoid downtown construction‐related traffic congestion. The construction effects on social resources are primarily the result of proximity to noise, air pollution, and light and glare from the construction activities in the project corridor. They may also include changes in property access, traffic detours, loss of parking, and the effects of the construction staging areas. Any changes to residential land uses and population f...
Construction Impacts. Sound Transit shall provide a Construction Management Plan which shall provide for mitigation of impacts on Xxxxx Xxxx. Xxxxx Xxxx has many teaching and research functions that operate on a 24-hour 7 day a week basis. Many of these spaces are located on the south side of Xxxxx Xxxx, facing the Sound Transit construction activity. These spaces include: the College of Architecture and Urban Planning Library, the CAUP shop and a number of classrooms, including a computer lab. In addition, there is an exterior courtyard south of Xxxxx, which is in fact an outdoor classroom associated with the shops. The CAUP Library operates seven days a week. The computer lab operates 24 hours a day, seven days a week. The shop area is available and in use by students for that same period. The Sound Transit Construction Management Plan required by Appendix C shall include provisions that addresses the following:

Construction Impacts. Emissions of criteria pollutants from fugitive dust and construction equipment will be estimated using the URBEMIS2007 Environmental Management software, emission factors and tools from the BAAQMD, California Air Resources Board (CARB), and/or the U.S. Environmental Protection Agency (EPA), as needed, and the construction schedule and equipment activity levels (if available) provided by the District. The construction impact analysis will also reflect the use of control measures that are required by the BAAQMD, including the use of fugitive dust and exhaust control measures. If warranted, the project may also be required to implement additional control measures pursuant to the BAAQMD guidelines. The emissions will be compared with the BAAQMD recommended construction emissions thresholds. If significant construction air quality impacts are identified, we will incorporate additional mitigation measures. In addition, if necessary, we will provide a discussion of the California Asbestos Airborne Toxic Control Measure (ATCM) for Construction, Grading, Quarrying and Surface Mining Operations. The ATCM is enforced by the BAAQMD through its naturally-occurring asbestos (NOA) program.
