Title
Orland Park Nature Center additional engineering services and Phase II Environmental Study
History
In April 2012, the Village purchased the former Pebble Creek Nursery property with funds from the Village's Open Lands Program, with the vision to restore and preserve the land, and to convert the existing building and property to a nature center. The property was since been cleaned up and a conceptual Master Plan approved by the Village Board in 2015.
Engineering addendum
Upland Design was contracted by the Village in February 2016 for a total of $62,761 to produce engineering and construction plans, bid documents and construction oversight for the Nature Center site improvements. As preliminary engineering for the project progressed, it became evident that currently available flood plain elevation information did not adequately meet the Village’s engineering requirements for the project. CBBEL, the Village’s engineering consultant, recommended that the needed floodplain elevation be obtained from existing studies recently done nearby or from new floodplain modeling and analysis. Although every attempt was made to utilize existing studies, the information was neither current enough nor specific enough to the Nature Center site to satisfy Village engineering requirements. Flood plain modeling was not included in Upland’s 2016 contract. The flood plain elevation is needed to move the Nature Center project forward, and will also be useful in future restoration projects in the onsite wetland area that also extends beyond the Nature Center site. Upland Design has submitted a quote of $5,100 for the following tasks, which will be included in an addendum to their current contract:
1) Obtain MWRD model and analyze: coordination with CBBEL, IDOT, and MWRD to obtain the Mill Creek model, run the hydrologic model, run the hydraulic model, and analyze results.
2) Field Survey: supplemental topographic and utility data needed to update the Mill Creek model.
3) Update ...
