306DSCENIC ROUTES306D.1Statement of purpose — intent.1The general assembly finds that:aThe state offers numerous regions through which people can drive for the pleasure of viewing unusually scenic and interesting landscapes; however, routes to and through these areas have not been adequately identified for Iowans and state visitors.bAmong those things that attract motorists to the state’s landscape are agricultural lands, forests, river basins, distinctive landforms, interesting architecture, metropolitan areas, small rural towns, and historic sites.cThe landscape qualities of unusually scenic routes throughout the state have not been protected from visual and resource deterioration particularly along routes which pass near the state’s nationally significant areas such as the bluffs of the Mississippi and Missouri rivers, the Amana colonies, the Herbert Hoover national historic site, federal reservoirs, communities surrounding the state’s natural lakes, the Des Moines river greenbelt, the great river road, and many others.dA principal goal of economic development in this state is to increase the influence which travel and tourism have on the state’s economic expansion.eIowans and visitors should be encouraged to travel to and through unusually scenic areas of the state.fA program should be established, following a statewide plan, to identify and promote highways and secondary routes which pass through unusually scenic landscapes and to protect and enhance the scenic qualities of the landscape through which these routes pass.2In addition to other goals for the program, it is the intention of the general assembly that the scenic highways program be coordinated with the state’s open space program under chapter 465A.87 Acts, ch 175, §1; 2014 Acts, ch 1092, §64306D.2Statewide scenic highways program — objectives and agency duties.1The state department of transportation shall prepare a statewide, long-range plan for the protection, enhancement, and identification of highways and secondary roads which pass through unusually scenic areas of the state as identified in section 306D.1. The department of natural resources, the economic development authority, private organizations, county conservation boards, city park and recreation departments, and the federal agencies having jurisdiction over land in the state shall be encouraged to assist in preparing the plan. The plan shall be coordinated with the state’s open space plan if a state open space plan has been approved by the general assembly.

The plan shall be submitted to the general assembly by January 15, 1988. Prior to submission of the plan to the general assembly, the department shall request comments on the proposed plan from state agencies, federal agencies, and private organizations with interests in scenic highways.
