Traffic Signal at Fourth & Alameda Traffic Signal at Fourth & Alameda ProsCons  Provides breaks in Fourth Street traffic which would aid north/south crossings  Provides protected north/south crossing at Alameda Boulevard  Provides protected pedestrian crossings across both Fourth Street and Alameda Boulevard  If combined and sequenced with other downstream signals, signal progression could be set to move vehicle platoons at 25 mph  Alameda Boulevard is classified as a Minor Arterial  May receive neighborhood opposition  Some consider signals unsightly and too “urbanistic” for Coronado’s small town atmosphere  May cause additional delay on NASNI  Was previously rejected by City Council

Raised Crosswalks with Rapid Flashing Beacons on Fourth Street at I & H Avenues ProsCons  Improves pedestrian visibility  Designed for 25 mph speed  Narrows roadway and distance pedestrians must cross  Creates additional noise  Design must consider drainage  May lose on-street parking spaces  Not well received by motorists with low profile vehicles Fourth & I and Fourth and H

Intersection Modifications to Palm/G Avenues at Fourth Street ProsCons  Creates a standard four leg intersection with standard 90 degree angles  Reduces/eliminates pedestrian crossing distance of Palm Avenue  Provides additional opportunity for landscaping  Lessens vehicle exposure to the adjacent park  Reduces turning speeds onto/off of Palm Avenue  Prevents access across Fourth Street from Palm Avenue in both directions  Design alters access to some private residences

Traffic Signal at Fourth Street and F Avenue ProsCons  Provides breaks in Fourth Street traffic which would aid north/south crossings  Provides protected north/south crossing at F Avenue  Provides protected pedestrian crossings across both Fourth Street and F Avenue, a designated school crossing  If combined and sequenced with other downstream signals, signal progression could be set to move platoons of vehicles at 25 mph  May receive neighborhood opposition  Some consider signals unsightly and too “urbanistic” for Coronado’s small town atmosphere  F Avenue is classified as a local street

Keep Clear Pavement Markings ProsCons  Reminds motorists to keep the intersection clear  Provides better north/south access during most congested periods  Considered by some as unsightly and unnecessary Fourth & D

Curb Extensions at Fourth Street and C Avenue ProsCons  Improves visibility of the pedestrian  Shortens the distance pedestrian must cross while exposed to traffic  Narrows the roadway which can slow traffic  May eliminate on- street parking  Design must consider drainage Fourth & C

Traffic Signal at Fourth Street and B Avenue ProsCons  Provides breaks in Fourth Street traffic which would aid north/south crossings  Provides protected north/south crossing at B Avenue  Provides protected pedestrian crossings across both Fourth Street and B Avenue  If combined and sequenced with other downstream signals, signal progression could be set to move platoons at 25 mph  B Avenue is classified as a Collector Street  Strong neighborhood opposition  Some consider signals unsightly and too “urbanistic” for Coronado’s small town atmosphere  May increase traffic on B Avenue (projected at 1350 vehicles per day +/- between Third and Fourth Streets, 350+/- vehicles north of Third and 1000 vehicles +/- south of Fourth Streets )

Curb Extensions at Fourth Street and A Avenue ProsCons  Improves visibility of the pedestrian  Shortens the distance pedestrian must cross while exposed to traffic  Narrows the roadway which can slow traffic  May eliminate on- street parking  Design must consider drainage Fourth Street at A Avenue

Speed Tables on Fourth Street between A and Pomona Avenues ProsCons  Designed for 25 mph speed  Creates additional noise  Not well received by motorists with low profile vehicles Fourth Street between A and Pomona Avenue

Curb Extensions on Pomona Avenue at Fourth Street ProsCons  Improves visibility of the pedestrian  Shortens the distance pedestrian must cross while exposed to traffic  Narrows the roadway which can slow traffic  Reduces turning speed from Fourth Street onto Pomona Avenue  Provides a pedestrian refuge  May eliminate on- street parking  Design must consider drainage Pomona Avenue and Fourth Street

Traffic Signal & Cul-de-Sac at Glorietta ProsCons  Provides bridge access to the northeast quadrant of the City including Tidelands Park, Marriott Hotel and the Coronado Hospital  Signal timing could be adjusted for weekend volumes  Glorietta Boulevard is classified as a Collector Street  May cause increased traffic on Second Street and Glorietta Boulevard (projected at 1450 vehicles per day +/- on Second Street and 1600 vehicles per day +/- on Glorietta Blvd.)  Some consider signals unsightly and too “urbanistic” for Coronado’s small town atmosphere  May have neighborhood opposition  Affects access to private property

Traffic Circle at Third/Glorietta ProsCons  Controls traffic speeds along Glorietta Boulevard with stopping all vehicles  Somewhat removed from the corridor

Speed Table on Pomona Avenue between Fourth Street and Glorietta Boulevard at the split ProsCons  Designed for 25 mph speed  Creates additional noise  Not well received by motorists with low profile vehicles Pomona Avenue at the split

Intersection Modifications to Glorietta Place at Pomona Avenue ProsCons  Shortens the distance pedestrian must cross Glorietta Place while exposed to traffic  Narrows the roadway which can slow traffic  Reduces turning speed from Pomona Avenue onto Glorietta Place  Alters driveway access to three properties placing them onto the heavily traveled state highway Glorietta Place at Pomona Avenue

Modifications to A Avenue at Pomona Avenue ProsCons  Eliminates the fast turning movement from Pomona Avenue to A Avenue  Eliminates queueing from Fourth Street back to Pomona Avenue  Motorist will likely take B Avenue as an alternative; increasing volumes on B between Third and Fourth Streets A Avenue at Pomona Avenue
