IOWA: EXTRATERRITORIAL SUBDIVISION <br />CONTROL AND 28E AGREEMENTS <br />Cross - boundary planning in Iowa is somewhat <br />simpler than in Minnesota, since counties <br />and cities are the only entities with planning <br />authority. Under state law, cities have subdivi- <br />sion authority over a two -mile extraterritorial <br />jurisdiction outside their boundaries. <br />Mason City <br />Mason City recently adopted a new zoning <br />code based on the form -based SmartCode. <br />The city's zoning districts follow a transect <br />arrangement, from the Zi Agricultural to the <br />Z5 Central Business District. Much of the <br />outlying land within city boundaries remains <br />in agricultural use and zoning. The zoning <br />code and subdivision ordinance, both ad- <br />opted in 2010, are coordinated so that sub- <br />divisions of more than two lots within both <br />the Zi Agricultural District and the city's two - <br />mile extraterritorial area are only allowed if <br />they meet certain requirements: <br />O The site must be contiguous to an existing <br />neighborhood or can be readily connected <br />to an existing neighborhood or corridor by a <br />collector street. <br />O The site must be able to be served by <br />public utilities within a reasonable distance <br />as determined by the city engineer and de- <br />velopment review committee. <br />* A concept plan must be developed as part <br />of the application and show how the proposed <br />subdivision will fit into a complete planned <br />neighborhood of at least 4o acres in size. <br />Road, block, and lot standards within <br />the subdivision ordinance are consistent <br />with new urbanist concepts, emphasizing <br />interconnected streets, limited block length, <br />sidewalks, and trails. <br />According to Planning Director Pam <br />Myhre, the new ordinances are working well <br />and reducing the need for variances and <br />rezoning. There has been little subdivision <br />activity within the extraterritorial area, but <br />one recently proposed business park within <br />the city will be developing a concept plan <br />with the required street connections. <br />Linn County <br />Intergovernmental cooperation in Iowa is <br />strongly encouraged under state law: Chap- <br />ter 28E of the Iowa Code permits any gov- <br />ernmental agency to undertake any activity <br />jointly with any other agency so long as each <br />agency has the power to undertake that par- <br />ticular activity on its own. These joint and <br />cooperative arrangements have proved to <br />be an efficient and popular way of providing <br />services at a reasonable cost. <br />Linn County(surroundingthe city of Cedar <br />Rapids), has used "28E agreements" to develop <br />a series of City - County Strategic Growth (CCSG) <br />plans, enabling cities and the county to estab- <br />lish stable cooperative zoning arrangements for <br />growth areas outside city boundaries. As the <br />recent CCSG plan for the small city of Ely states, <br />"coordinated land use planning between a city <br />and county promotes compact growth patterns <br />in appropriate locations, reduces public infra- <br />structure costs, and encourages the retention of <br />viable agricultural operations and open space." <br />The planning process begins with a <br />Fringe -Area Policy Agreement, established <br />under Chapter 28E, that establishes atwo- <br />mile study area based on the city's extrater- <br />ritorial jurisdiction. Within that area, the city <br />and county agree to establish policies for <br />orderly growth. The Ely plan, for example, <br />designates most of the fringe <br />area for continued agricultural use and de- <br />fines three other areas surrounding the city: <br />O A rural residential area designated for <br />low - density development (i.e., rural roads, <br />wells, and septic systems) and not intended <br />for annexation <br />O An urban service area designated for resi- <br />dential development (i.e., developed with <br />densities compatible with city standards <br />and served by city utilities or its own cen- <br />tralized system) and intended for eventual <br />annexation <br />0 A small rural commercial area, intended to <br />allow limited highway - oriented commercial and <br />office uses and not intended for annexation <br />County zoning applies within each <br />area, with city approval required for all <br />zoning and subdivision applications. if an -. <br />nexation takes place, the county waives <br />its approval authority. The plan also estab- <br />lishes minimum levels of service required <br />for each land -use category at the time of <br />development, consistent with the county's <br />sophisticated Rural Land Use Plan. Services <br />include not only water and wastewater but <br />transportation (county road classifications) <br />and fire protection. <br />According to County Planning Director <br />Les Beck, Ely is currently growing rapidly and <br />expanding its boundaries through annexa- <br />tion, which effectively takes the county out <br />of the picture. Beck points out that while <br />strategic growth planning can work well, <br />the lack of regional population targets can <br />hinder agreement. For example, one city <br />currently working with the county on a fringe <br />area plan has identified a i,000 -acre growth <br />area based on its own population projec- <br />tions, while county planners believe that a <br />15o -acre area would be sufficient. <br />The 28E agreement process may be <br />most effective in establishing protocols for <br />development review in order to implement <br />an urban fringe area plan.
