Do slope protective ordinances Really protect?

Using case studies, we will examine whether slope protective ordinances intended to protect property actually provide the intended protection or do they simply provide a false sense of safety to building officials and property owners.

A slope failure in one of the communities in the Chagrin River Valley in the early 1990s damaged a privately-owned structure. The cost of remedial measures was much greater than what most communities and property owners could manage. This prompted the community to enact a slope protective ordinance. Other towns and villages along the valley quickly followed suit enacting similar ordinances. The stated purpose and justification for these ordinances is to protect public safety, property, and the environment. Various methods are used to define protected areas which are essentially "no build zones" on parcels with steep slopes.

As the case studies illustrate, sloping sites are too varied, and conditions that control slope stability are too complex, to be addressed by including a few generic requirements in municipal ordinances. Such ordinances understandably avoid codifying minimum factors of safety, or dictating what is required for a proper geotechnical evaluation of a sloping site. Whether these ordinances are successful in achieving their goal depends on enforcement and the skill and experience of those tasked with complying with the provisions of the ordinances.
