    Stormwater outfall Available utilities Existing right of way or sundry site Potential for future expansion

    Purchasing or leasing property increases costs substantially. Therefore, the first choice is state-owned right of way, assuming the other selection criteria are favorable. Also give prime consideration to the use of city- or county-owned right of way. Select a site that does not jeopardize the current and future integrity of the highway.

    Investigate each potential site in the field. The field survey serves to confirm or revise impressions gained from the office review. When conducting the investigation, consider the following:

    Physical characteristics of the site. Current use and zoning of the area. Whether the site is visible from adjacent streets (to enhance security). Potential for additional expansion. Accessibility for motorists and other modes of travel, including transit. Proximity of any existing parking facilities (such as church or shopping

    center parking lots) that are underutilized during the day. Potential for joint use of facilities with businesses (such as day care centers

    or dry cleaners) or land uses compatible with park & ride patrons. Congestion and other design considerations. Avoid locations that encourage noncommuter use (such as proximity to

    a high school).

    The desirable location for park & ride lots along one-way couplets is between the two one-way streets, with access from both streets. When this is not practicable, provide additional signing to guide users to and from the facility.

    Establish potential sites, with transit agency input, and com
