DHPA Grant Cycle 1995 9-28-94 PROPOSAL SUMMARY Project: Riverside Drive Bank Stabilization Feasibility Study DHPA Priority Area: Architectural/Historical Project Description: Provide landscape architectural and engineering services to determine the cause of and generic remedies (or mediation techniques) for bank slump which threatens structures in the Chapin Park National Register Historic District and Riverside Drive Local Historic District. The anticipated work product would be a manual which is understandable to a lay -person (property owner) which gives direction to activities (which are otherwise environmentally acceptable) which will act to conserve the riverbank and resident structures. Comments: This project is a response to encroaching environmental conditions which threaten designated historic structures. Many of these structures have at one time had passive recreation facilities down the bank (stairs, terraces, etc.) of which traces remain. There are many active springs on the bank. The condition may be characterized by a high bluff with structures built close to its edge. This location is on the outside bank of a curve in the St. Joseph River. Apparently the washing away of soil at the river water level results in corresponding slump at the top of a moderately steep hillside, which has now come dangerously close to existing structures, undermining existing foundations, etc. Piecemeal approaches by property owners have had various positive and negative effects. A comprehensive plan is required to inform property owners of appropriate and inappropriate responses to the bank conservation problem. Other related issues which will require consideration are restrictions and necessary procedures related to potential effects on the river wildlife, flow, and other concerns of the Army Corps of Engineers, Indiana Department of Natural Resources, etc. David B.
