Thisaddendum specifically addresses the Preferred Alternative as identified by AC Transit and the cities ofBerkeley, Oakland, and San Leandro following publication of the Draft Environmental ImpactStatement/Environmental Impact Report (DEIS/EIR) for the proposed project. Additional information isalso provided in response to comments received during public review of the DEIS/EIR.</p><p>The proposed East Bay Bus Rapid Transit (BRT) project (Project) is an upgrade transit service spanningfrom downtown Berkeley to San Leandro BART in San Leandro, a distance of approximately 14 miles. Adetailed noise analysis following Federal Transit Administration (FTA) criteria and procedures wasperformed to determine potential noise impacts resulting from implementation of the project.</p><p>The Project would incorporate bus-only lanes in the center of the road along portions of TelegraphAvenue, International Boulevard, and East 14th Street. The Project would allow buses to offer riders arail-like transit experience that operates more quickly and reliably than regular bus service today.</p><p>The criteria in the Transit Noise and Vibration Impact Assessment guidance manual (FTA 2006) wereused to assess existing ambient noise levels, future noise impacts, and construction noise as a result of theProject. The impact criteria for noise generated by Project construction were established throughexamining the municipal codes of local jurisdictions within project limits.</p><p>A Project site reconnaissance was performed to identify noise-sensitive receptors and to conduct noisemeasurements. Noise-sensitive land uses potentially affected by the Project consist of single-familyresidences, multi-family residences, schools, and parks. Existing noise level measurements wereconducted to estimate existing ambient noise levels in the vicinity of the Project area. Five long-term (24-hour) measurements and 14 short-term (20-minute) noise measurements were conducted at noise-sensitive locations.</p><p>Existing traffic noise levels and future traffic noise levels with and without the Project were estimatedusing the Federal Highway Administration (FHWA) Traffic Noise Model (TNM) version 2.5. Trafficvolumes were obtained from the Project traffic impact analysis. Future-with-Project noise levels andProject-generated noise level increases were evaluated against FTA criteria. Traffic noise impacts as aresult of the Project would be less than significant.</p><p>Operation vibration impacts would be less than significant.</p><p>Construction of the Project would generate a temporary increase in noise at noise-sensitive receptors inthe Project area. Construction noise levels would exceed FTA and local construction noise limits withoutmitigation. Project-generated construction noise impacts would be less than significant with mitigation.</p><p>Vibration levels associated with construction of the Project would be less than significant with mitigation.</p></li><li><p>K:\OAK_TPTO\097958005 2011 AC Transit FEIS-R\Tech Reports\Noise\East Bay BRT Noise Analysis Report 2011-11-17.doc 2</p><p>1.0 INTRODUCTION</p><p>This Noise and Vibration Impact Assessment Technical Report Addendum assesses potential operationaland construction noise and vibration impacts along the proposed Alameda Contra Costa (AC) TransitEast Bay BRT alignment. The AC Transit District proposes to upgrade bus service to a high-level busservice along an approximately 14-mile arterial corridor through the cities of Berkeley, Oakland, and SanLeandro, in the East San Francisco Bay Area of California. The project location and vicinity are shown inFigures 1 and 2, respectively.</p><p>The assessment describes the existing noise environment, reports regulatory requirements, estimatesexisting traffic noise conditions in the project area, identifies noise sensitive locations, predicts futuretraffic noise levels, and provides an assessment of the potential noise and vibration impacts of theproposed Project. The estimated changes in noise levels resulting from the Project are compared toapplicable guidelines contained in Federal planning documents to determine significance.</p></li><li><p>AC Transit BRT System Figure 1Regional Map</p><p>Proposed BRT System Project Area</p><p>Legend:</p><p>Noise and Vibration Impact Assessment Technical Report AddendumF1 inch = 30,000 feet</p></li><li><p>580</p><p>880</p><p>123</p><p>13</p><p>24</p><p>13</p><p>E 14th St</p><p>High S</p><p>t</p><p>Otis Dr</p><p>Bancroft Ave</p><p>7th St</p><p>Pacific Ave Foothill Blvd</p><p>Davis St</p><p>35th A</p><p>ve</p><p>Clar</p><p>emon</p><p>t Ave</p><p>Adel</p><p>ine </p><p>St</p><p>Pinehurst Rd</p><p>College A</p><p>ve</p><p>13th A</p><p>ve</p><p>Alcatraz Ave</p><p>Park Blvd</p><p>San Pablo Ave</p><p>Park</p><p> St</p><p>International Blvd</p><p>Skyline Blvd</p><p>8th St</p><p>Dwight Way</p><p>14th Ave</p><p>Ashby Ave</p><p>Encinal Ave</p><p>Frui</p><p>tval</p><p>e Av</p><p>e</p><p>Broadway</p><p>Sacramento St</p><p>San Leandro St</p><p>Snake Rd</p><p>73rd A</p><p>ve</p><p>Monterey Blvd</p><p>Gra</p><p>nd A</p><p>ve</p><p>Broadway</p><p> Ter</p><p>Moraga Ave</p><p>Tele</p><p>grap</p><p>h A</p><p>ve</p><p>23rd</p><p> Ave</p><p>98th Ave</p><p>Doolittle Dr</p><p>Oakport St</p><p>51st St</p><p>Linco</p><p>ln Av</p><p>e</p><p>Central Ave</p><p>16th St</p><p>Broa</p><p>dway</p><p> St</p><p>Ron Cowan Pkwy</p><p>Redwood Rd5th St</p><p>Moraga W</p><p>ay</p><p>Mandana Blv</p><p>d</p><p>Hege</p><p>nber</p><p>ger R</p><p>d</p><p>Cast</p><p>ro S</p><p>t</p><p>Airport </p><p>Dr</p><p>Isla</p><p>nd D</p><p>r</p><p>66th A</p><p>ve</p><p>Vers</p><p>aille</p><p>s Ave</p><p>Shattuck Ave</p><p>MacArthur Blvd</p><p>Piedm</p><p>ont A</p><p>ve</p><p>Coliseum Way</p><p>12th St</p><p>Maitland Dr</p><p>Joaquin Miller Rd</p><p>Clay</p><p> St</p><p>University Ave</p><p>Marina B</p><p>lvd</p><p>Bancroft Way</p><p>Mecartney Rd</p><p>Lakes</p><p>hore </p><p>Ave</p><p>Har</p><p>bor B</p><p>ay P</p><p>kwy</p><p>Sea View Pkwy</p><p>Stanfo</p><p>rd Ave</p><p>Mar</p><p>ket S</p><p>t</p><p>Dutton Ave</p><p>Tunnel Rd</p><p>Holly</p><p> St</p><p>Hege</p><p>nberg</p><p>er Ex</p><p>py</p><p>42nd A</p><p>ve</p><p>Marina Dr</p><p>Lym</p><p>an R</p><p>d</p><p>Juana Av</p><p>e</p><p>Sheffield Rd</p><p>40th St</p><p>Kennedy St</p><p>Crocker A</p><p>ve18th St</p><p>Webster St</p><p>8th St</p><p>8th St</p><p>Coliseum Way</p><p>Skyline Blvd</p><p>Broa</p><p>dway</p><p>Sacramento St</p><p>Doolittle Dr</p><p>AC Transit BRT System Figure 2Vicinity Map</p><p>Center-Running BRT Route</p><p>Legend:</p><p>Noise and Vibration Impact Assessment Technical Report AddendumF1 inch = 6,000 feet</p><p>Mixed Flow BRT RouteSide-Running BRT Route</p></li><li><p>K:\OAK_TPTO\097958005 2011 AC Transit FEIS-R\Tech Reports\Noise\East Bay BRT Noise Analysis Report 2011-11-17.doc 5</p><p>1.1 PROJECT DESCRIPTION</p><p>This section describes the Locally Preferred Alternative (LPA) and the Downtown Oakland- San LeandroAlternative. Basic features of the proposed East Bay BRT Project include transit priority at all signalizedintersections, new passenger stations, and a combination of mixed-flow and dedicated travel lanesthroughout the proposed project alignment. As described in more detail below, the East Bay BRT willtake the place of existing Rapid Bus Routes 1 and 1R currently operating in the corridor.</p><p>1.1.1 Locally Preferred Alternative</p><p>1.1.1.1 Features</p><p>BRT Transitway</p><p>The BRT transitway is the lane or lanes in which BRT buses would operate. There are three basic types oftransitways proposed for different segments of the East Bay BRT project:</p><p>Dedicated lanes (BRT-only lanes) e.g. International Boulevard</p><p>BRT lanes shared to a limited extent with mixed traffic e.g. 11th and 12th Streets</p><p>Mixed-flow traffic lanes in which BRT buses are provided no special treatments e.g. DavisStreet in San Leandro</p><p>General attributes of these transitways are summarized below. The locations of these transitwaysproposed in the East Bay BRT corridor are discussed in detail in Section 1.1.2: Alignment.</p><p>Dedicated Lanes</p><p>Dedicated or BRT-only lanes would be used by BRT and emergency vehicles, the latter only whennecessary for expedited travel. Dedicated lanes would be located in the median of the street or, in somelimited cases, in the outside travel lanes (the lane closest to the curb). The choice of location is based ontraffic and land use conditions in the particular area. Cross traffic would not be allowed to cross median-running dedicated lanes except at signalized intersections where space for turning movements is carefullyintegrated into transitway design. Of the 14.38-mile project, approximately 10.92 miles, or 76 percent ofthe corridor, consist of dedicated BRT lanes.</p><p>Within side-running dedicated lanes, access to the lanes would be provided to vehicles needing to maketurns or for entering or exiting parking spaces. Use of the lanes by through traffic would be prohibited.Cross traffic would be allowed to cross side-running dedicated BRT lanes between signalizedintersections. Side-running dedicated BRT lanes would be implemented on one-way arterials androadways with limited opportunities for median BRT improvements.</p><p>Mixed-Flow Traffic Lanes</p><p>Mixed-flow lanes for BRT operations are proposed in areas where dedicated or shared lanes are notfeasible. These locations include high traffic bus-auto zones and narrow, capacity-constrained streets</p></li><li><p>K:\OAK_TPTO\097958005 2011 AC Transit FEIS-R\Tech Reports\Noise\East Ba...</p></li></ul>
