Date: March 8, 2006 Application Number: Property Location: Property Owner: STAFF REPORT CONCERNING APPLICATION FOR A CERTIFICATE OF APPROPRIATENESS 2006-0224 Shetterly Park, 1007-1029 Riverside Drive City of South Bend Landmark or District Designation: Riverside Drive Local Historic District Rating: Defining Landscape Feature STATEMENT OF SIGNIFICANCE/HISTORIC CONTEXT: Shetterly Park is an element of the Riverside Drive District that sets it apart from other Local Historic Districts and provides a natural green space enclosure along Riverside Drive that serves as buffer from urban noise. It serves as a tie to the St. Joseph River by providing usable space close to the water and a visual link to the West North Shore Local Historic District. APPLICATION ITEMS: This project is an emergency repair to an existing Combined Sewer Outfall (CSO) that is part of the City of South Bend Sanitary Sewer System. This is also considered an emergency project by the DNR and by IDEM. The CSO pipeline runs parallel to the northwest property.line of 1012 Riverside Drive in Shetterly Park. In order to repair the pipeline and install odor abatement equipment it will be necessary to create a permanent access ramp along the slope of Shetterly Park beginning northwest of the CSO pipeline and traveling at a 20% grade eastward toward a landing area (also permanent) near the location of the CSO pipeline. To accommodate the 20% grade a larger swath of the slope will need excavated to accommodate the machinery. (See Exhibit 1) An adjoining access ramp will be constructed along the western shoreline of the St. Joseph River. When the project is completed the access ramp along the western shoreline will be re -graded and planted to reclaim the shoreline and provide for erosion control. The area surrounding the pipe area will also be treated for erosion control with the use of riprap, silt fence, etc. The swath along the slope will be replanted with seedlings and saplings and ground cover. The permanent access ramp and landing area will be naturalized with plantings and natural materials that will maintain by the CSO crew. (See Exhibit 2) Grass in Shetterly Park will be re -seeded. Jason Durr, Assistant City Engineer with Department of Public Works and Steve Ernst, Civil Engineer with Christopher B. Burke Engineering are working with City Forester, Brent Thompson concerning the removal and replanting of trees and ground cover in Shetterly Park. Brent Thompson is also going to present a Planting Plan for this project at the HPC meeting. STANDARDS FOR RIVERSIDE DRIVE: I. ENVIORNMENT, Required: Distinctive existing features such as parks ... shall be retained. New plant materials... shall be compatible with the character of the neighborhood....Recommended: ...If erosion control efforts become necessary to preserve the riverbank, they should involve processes and materials consistent with the natural beauty of the bank. Large deep-rooted trees and shrubs as well as fast spreading ground cover should be used when planting for erosion control. As much natural vegetation as possible should be preserved. RECOMMENDATION: Staff recommends approval. The remedies proposed for the repair of the brick CSO and its maintenance along with its solutions to air and water pollution are sensitive to the current and future landscaping of Shetterly Park and the Riverside Drive District. -
