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
5
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
6
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
7
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
8
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
9
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
10
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 )
11

12
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
13
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
14
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 Fourth Street between A & Pomona Avenues ProsCons Designed for 25 mph speed Creates additional noise Not well received by motorists with low profile vehicles Fourth Street east of A Avenue
18
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
19
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

22
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 Third Street at C Avenue
23
