(A) All streets shall be constructed in conformance with the construction plans and specifications approved by the Director of Public Works, or a designated representative, and the City Engineer, or a designated representative.
(1) Designs should permit comfortable use of the street by motorists, pedestrians and bicyclists.
(2) Pavement widths, design speeds and the number of motor travel lanes should be minimized to enhance safety for motorists and non-motorists alike.
(3) The specific design of any given street must consider the building types that have frontage, and the relationship of the street to the overall city street network.
(B) The following specifications apply to street design:
(1) Street trees and sidewalks are required on both sides of streets, except rural roads, lanes, alleys and the undeveloped edge of neighborhood parkways.
(a) The planting area for street trees should be a minimum of five feet in width, and sidewalks should also be a minimum of five feet in width.
(b) On streets serving as main business streets, sidewalks should be a minimum of seven feet in width.
(c) Generally, canopy trees shall be planted at a spacing not to exceed 40 feet on center.
(d) Where overhead utility lines preclude the use of canopy trees, small maturing trees may be substituted, planted 30 feet on center.
(2) On-street parking is recommended where building type and use will generate regular use.
(a) Occasional on-street parking can be accommodated without additional pavement width.
(b) For streets serving workplace and storefront buildings, on-street parking is required and should be marked as such.
(c) On-street parking on at least one side of the street is also required on streets serving apartments, attached houses, and detached houses with lots 60 feet or less in width.
(d) On-street parking must also be provided on one side of any street adjacent to a square, park or other open-space area.
(e) Parallel, on-street parking width is seven feet to eight feet.
(f) On-street parking should be parallel; angled parking is only permitted as an intentional design element for the retail center of a planned, mixed-use development.
(3) Design speeds should not exceed 25 miles per hour on any neighborhood street. Only major town streets and boulevards should exceed this design speed.
(4) These specifications may be varied only in accordance with the design principles detailed above and as approved by the Director of Public Works, or a designated representative.
