3 Meeting Date: October 17, 217 provide replacement parking within a reasonable distance when metered parking spaces are restricted by the work. Revenue from the lost meters will be reimbursed by Metro. Work under this permit is expected to be completed by March 1, 218. The permit conditions will prohibit work on Wilshire Boulevard between Santa Monica Boulevard and Rexford Drive from November 23, 217 through January 1, 218. At other locations, work will be prohibited on specific holidays, including Thanksgiving, the day after Thanksgiving, Christmas Day and New Year s Day. The permit requires work to be performed in such a way that the noise generated by the operations shall cause no more than a 5dBA increase over ambient noise at any residential property line. Noise monitoring and enforcement provisions are included in the attached permit conditions. Prior to beginning work, Metro will conduct an ambient noise study to establish daytime and nighttime ambient noise levels at locations adjacent to the work. An Independent Compliance Monitor (1CM) is required to be on-site during all work activities to monitor the permit conditions, including noise levels. The 1CM has the authority to stop work if noise exceeds 5dBA over the ambient noise levels. The data collected during the geotechnical boring work and the report generated by the data will be provided to the City, per the permit conditions. Community Engagement The City, Metro and the Contractor walked notices to 38 businesses along Wilshire Boulevard on September 5, 217 and September 11, 217. These notices were also posted on social media and their respective websites and distributed to both the City and Metro s database. Representatives discussed the proposed geotechnical work with many owners/tenants along Wilshire Boulevard between Linden Avenue on the west and Carson Avenue on the east. A specific notice and map was developed for each boring location that detailed work to be conducted, proposed work hours and duration, traffic control plans and contact information. Most persons contacted did not have any major concerns about the work and those that had concerns asked questions about the duration, time of day and if there would be any impacts on parking or access to their location. Additionally, Metro conducted briefings with stakeholders in the project area in August 217, including Spago, Citizen, Montage Beverly Hills, Beverly Wilshire Investment Company, AKA Hotel, Sirtaj Hotel, and the Sixty Hotel. No major concerns were raised about the geotechnical work. These briefings were followed-up by s and phone calls in September, 217 to offer additional information, briefings and an invitation to the community meeting held at City Hall on September 13, 217. At the monthly Beverly Hills Purple Line Extension Community Meeting held on September 13, 217, Metro informed the public of the proposed geotechnical boring work and presented a map of the locations and traffic control plans. Metro also hosted a booth at the City s Next Night event on September 23, 217 to share information on this and other upcoming work in the City. On September 25, 217, Metro s canvassing vendor distributed a flyer to 9, addresses in the Section 2 area to include all areas where geotechnical boring testing will take place (Attachment 3). This flyer included detailed information about the geotechnical borings and potholes including a map of day and night work locations, work hours, contact Page 3 of 4 1/13/2 17

4 Meeting Date: October 17, 217 information, and provided information about the September 28th Community Meeting. Since residential properties are directly behind the commercial corridor, and much of the work is proposed to be completed at night, Metro conducted additional targeted outreach to these residential buildings. No calls or s to the project hotline were received regarding this notification. Metro is working with the Academy of Motion Pictures Arts and Sciences to confirm that geotechnical work will not occur adjacent to the theater during an event. Metro and the City have reached out to the Southwest Homeowners Association (HOA) to inform their members of the upcoming work and ensure that they are aware of upcoming Community Outreach meetings. An additional Section 2 Community Meeting was held on September 28, 217 in Century City where the proposed geotechnical boring work was presented to the public. There were approximate twelve (12) residents from Beverly Hills present and no concerns were raised about the geotechnical borings. On October 11, 216 Metro and the City held a joint monthly community meeting. The presentation included maps, work hours, work activities and details about the geotechnical investigation. Questions from the audience, which included both residents and business owners, focused on what the findings would be used for and if data would be available for the public. Metro informed them that they have agreed to share the information gathered from the investigation. Residents from the Southwest HOA also asked about noise and dust mitigation and Metro and City Staff were able to respond to there concerns. Metro is also required to maintain their public hotline number ( ) to continue to be responsive to concerns about the work from the public. FISCAL IMPACT Costs associated with reviewing or processing this permit application will be reimbursed by Metro. Page 4 of 4 1/13/217

Configure traffic pattern to minimize backing movement. No slamming tailgates. Establish truck cleanout staging areas as needed. Use rubber gaskets or functional equivalent or decrease speed of closure. Fit with manufacturer approved exhaust muffler. Enclose pavement breaker and cutting activities with a noise barrier fence. The use of vibratory rollers and packers will be avoided near vibration sensitive areas and structures. The vibration sensitive areas and structures shall be determined by a structural engineer as part of the preconstruction surveys and subject to verification by the City. No truck traffic shall be permitted on residentially zoned streets, except for access to laydown yards when necessary and only by using a route approved by the City. Use modern equipment equipped with state of the art engine insulation and mufflers, in accordance with all applicable City, State, and Federal standards. Where a generator is necessary, it shall be equipped with the best available technology to minimize noise. Operate equipment at the lowest possible power levels. Provide noise muffling enclosures for fixed equipment. Provide noise awareness training to contractors/workers. Use solar, battery powered, or hybrid equipment whenever practical. Place plywood or dirt beds on all trucks or any other mutually agreed to effective noise mitigations when loading concrete or steel on beds of trucks. Page 6 of 1

15 The following path mitigation techniques shall be employed at all times to reduce the impact of construction noise: Use of temporary noise barriers and sound control curtains or an equivalent form of solid object to either destroy part of the sound energy by absorption, or to redirect part of the energy by wave deflection. All jackhammers, pavement breakers and saw cutters used at the Construction site shall be enclosed with shields, acoustical barrier enclosures, or noise barriers. Sawcutting, jackhammering, and the use of vacuum trucks is prohibited between the hours of 9:3 PM and 9 AM. Enclose activities likely to create a noise disturbance and enclose stationary equipment. Employ sound blankets over a movable fence for all night work, including the use of state-of-the-art technology where necessary to achieve no more than 5dBA above pre-existing ambient noise levels at the property line of the nearest residential building. If sound blankets are to remain in place for more than five (5) Days, the LACMTA must seek approval from the City. Employ targeted noise mitigation when Construction is proximate to historic structures and may exceed 5dBA (Leq 15 mm) above pre-existing ambient noise levels during business hours at historic structures. If any activity conducted between the hours of 1 PM and 7 AM causes an unreasonable noise impact to the surrounding neighborhood, reasonable mitigation shall be implemented to reduce the impact to a reasonable level. Reasonable mitigation may include requiring work to be performed only between 9 AM and 4PM. When determining whether an impact is unreasonable, the City shall take into account the hour of day, the proximity to the work site, and other similar factors. b. Construction noise levels at all times will be limited to no more than 5 dba above pre-existing ambient noise levels at the property line of any residential building ( the Noise Standard ). Noise monitoring will be evaluated on a 15-minute average noise level (Leq 15 mm). In the event that the City identifies a potential violation of this Noise Standard at a property line where the ambient noise level has not previously been established: (1) the City shall use the ambient noise level established at the nearest pre-existing monitoring location unless and until a new ambient noise level is established at the location of the potential violation; (2) LACMTA shall take the steps necessary to meet the Noise Standard at the location of the potential violation; and (3) LACMTA may elect to jointly establish with the City a new ambient noise level at the location of the potential violation. The City shall then use the ambient noise level established at the pre-existing location or the newly established ambient level, as applicable, as the baseline for determining whether to impose a monetary contribution as provided for under Enforcement of Permit Conditions and Mitigation Measures section. 8. Light Plans and Mitigation Measures To minimize the impact of temporary lighting on adjacent properties, the following mitigation measures shall be implemented: Lighting will be directed downwards and shielded. Care shall be taken in the placement and orientation of portable lighting fixtures to avoid directing lights toward sensitive receptors, including automobile drivers. Page 7 of 7

16 Temporary lighting will be limited to the amount necessary to safely perform the required work and ensure pedestrian safety. In addition to minimizing light spill, sensitive receptors and motorists on public streets will not have direct views of the light source (glare) from construction lighting. Light sensitive receptors include but are not limited to residential areas. Light trespass shall not exceed one foot-candle above ambient light level as measured at any adjacent property. 9. Enforcement of Permit Conditions and Mitigation Measures a. When the Compliance Monitor finds that the LACMTA or its contractors have violated the terms of this Permit ( the Permit Conditions ), the Compliance Monitor shall provide documentation of the violation to both the City and the LACMTA within twenty-four (24) hours of the violation. The LACMTA shall provide a response to the nonconformance report within forty-eight (48) hours that shall include a description of the investigative actions taken to resolve the nonconformance, a description of the cause of the nonconformance, the actions taken or planned to correct the nonconformance, and the actions taken to prevent recurrence of the nonconformance. b. The Compliance Monitor shall have the power to order compliance with the Permit Conditions. lithe Compliance Monitor identifies two or more violations of the same Permit Condition with impacts on the same business, residence, or within a one hundred fifty (15) foot radius of the violation, within a ten (1) Day period, the LACMTA shall be required to make a monetary contribution into a fund established for the purpose of mitigating construction impacts on businesses and residents impacted by the construction: Violation 2: Violations 3 or more: $15, per violation $25, per violation c. The City shall control the fund established by this Article and shall direct expenditures to mitigate construction impacts on businesses and residents upon finding a link between the violation and the impact to businesses or residents. All mitigations implemented with the fund will comply with all applicable Federal regulations and guidelines. d. In addition to any monetary contributions, the Compliance Monitor may order an immediate halt to the work causing a violation or prohibit work that would imminently and obviously cause a violation until the LACMTA, its contractors or other third parties take action to correct the violation and prevent the violation irom being repeated. lithe work is halted or prohibited, the Compliance Monitor shall not allow resumption of the work causing the violation or that would imminently and obviously cause a violation until the violation is resolved and will not be repeated. The Compliance Monitor may only preemptively halt the work if the work would cause a violation of a specific Permit Condition that leaves no room for discretion, such as a failure to utilize proper noise mitigation equipment or conducting work at an unpermitted time. e. The Compliance Monitor shall also order a halt to any work that poses a clear and immediate threat to public safety. If work is halted for reasons of public safety, the Compliance Monitor shall not allow resumption of the work until the threat to public safety has been abated. 1. Advance Notification Process and Establishment of a Public Phone Line Page 8 11

17 The LACMTA shall be responsible for all advance notifications to the public for work associated with the Project. The notification distribution area shall be reviewed and approved by the City.
