Staging Yard Mitigation La Cienega ga Yard Gale Yard • • Active ventilation fans and fan 14’ fences with sound blankets placed lines were wrapped with sound around the crane • blankets Applied an acoustic dampening material to the 895 crane engine enclosure • • 24’ steel frame placed around Added a muffling panel on the exhaust the ventilation system with door and engine compartment door • sound blankets Relocated slew alarm • Added a noise barrier rubber mat to the • Sound blankets surrounding lower engine panels • the ventilation system have been Acoustic plate under mounted on the upgraded allowing for more crane counterweight • sound absorption Adjusted the crane start up schedule, when possible • Started closing the gate, when feasible • Installed noise dampening louvre adjacent to crane motor 12

Station Naming Policy Station Names will reflect the following principles • Transit system context: xt: names will reflect the property’s location, relative to the entire transit system, and not duplicated elsewhere. • Property rty area: provide specific information about the property’s location relative to the surrounding area. • Neighb hbor orhood hood identity: ty: acknowledge the communities and neighborhoods serviced by the station and stops. • Simpli licity: city: names will be short, easily recognizable and fit for signage and mapping. 13

Name your next Purple Line Stations Metro staff originally developed a set of geographically-based names for the Section 1 Stations and are now seeking community input on those names. Submit your proposals at metro.net/purple 14
