The challenges presented by coastal dynamics along the shoreline of Lake Michigan are unique within the State of Indiana. Although there are other navigable waters, there are no other water bodies within the state whose shores require the same technical understanding.

Most of the Indiana shoreline which might be prone to erosion and its consequential harm to the environment and property values has already been protected. The seawalls, breakwaters, jetties, and other shoreline protection structures in existence are aging and will require repair and replacement. The state and federal governments have the legal authority to address these structures within Lake Michigan, and local governments have the authority to address issues posed to their communities through the development of ordinances. Partnerships may be developed between state and local governments along the model offered by Ogden Dunes (LM-103), or model ordinances could be drafted which local governments might reference to address their own particular conditions. Technical data on shoreline erosion potential could be refined and made more readily accessible to local governments and individuals.


Methodologies and policies might be pursued to encourage beach nourishment to mitigate harm from erosion caused by existing structures. The U.S. Army Corps could be advised by state and local officials of the continuing need for its participation in beach nourishment activities. A revolving loan fund or other funding source could be developed for the state's beach nourishment statute. An interagency task force could be convened to develop testing standards (both for dredged sand and accumulation of excess sand landward of the shoreline) and regulatory streamlining to encourage the usage of clean sand for beach nourishment. Engineering advances could be encouraged to develop sand bypassing systems around existing structures which impede littoral drift.

Model ordinances might also be drafted to help assure that coastal redevelopment proceeds in the manner most likely to assure the future social and financial health of the communities. For example, set-back requirements for new structures might be established. Draft ordinances for modular structures might be prepared similar to legislation applicable in Michigan.
