The urban development concept plan should be designed to current subdivision standards for urban development. In designing the subdivision, the following considerations should be made:
a. The proposed street layout for the urban subdivision overlay may, at the discretion of the city council, be required to integrate with the rural plat to maximize the use of existing built roadways and connections to off site systems. All street rights of way for the urban development concept plan may, at the discretion of the city council, be required to be platted as part of the rural plat to secure the integrity of future urban platting.

House pad locations for the rural development may, at the discretion of the city council, be required to be indicated on the concept plan and be consistent with urban zoning standards so as to maximize efficient resubdivision of the rural lots into urban lots.
c. Areas for potential park land dedication and trail connections shall be identified as outlots that are suitable for dedication to the city if required by the city council.
d. The potential location of easements for drainage, municipal water, sanitary sewer, and storm sewer systems may, at the discretion of the city council, be required to be shown in the urban development concept plan, including connection points for utility systems at the plat boundaries. Such easements may be required to be dedicated together with the rural plat if the city council requires it.
