PROJECT UPDATE  A Review of MSA Projects in Your Community City of Tiffin, IA CLIENT LIAISONS: Kevin Bailey, PE / Jake Huck, P.E. Office: 319.364.4773 Cell(s): 319.855.8392/ 563.542.6571 [email protected] / [email protected] DATE: February 6, 2023 ON-GOING PROJECTS North Park Road Improvements MSA has completed all field topographic surveys for the project and completed the base map to begin design. The proposed design alignment has been established along with the typical sections (roadway width, sidewalk and trail widths) for the corridor. Utility coordination is on-going. The Team is evaluating optimal locations for the proposed grade-separated pedestrian crossing. Preliminary design efforts continue as the Team works to prepare the Concept Statement for the project. The Concept Statement will be submitted to the IowaDOT on or before March 21, 2023. Highway 6 Concept and Cost Estimate MSA submitted conceptual plans and typical section to the Iowa DOT for review on July 25, 2022. The IowaDOT provided comments on December 20, 2022. MSA is revising the typical sections for pavement depths based on the IowaDOT comments. The concept, typical sections and cost estimate will be finalized in February. Comprehensive Water System Evaluation MSA has nearly completed the water model. Once completed, MSA will review the model with the City staff. MSA has contacted Harn RO Systems and Wigen Water Technologies for proposals to complete the pilot testing for the Reverse Osmosis (RO) System. Harn is the only manufacturer that provided pricing. The piloting proposal was about $70,000. Including the City’s responsibilities, the total estimated cost for the piloting would be about $90,000. These piloting costs are reimbursable through the SRF Planning and Design loan if the City want to pursue for financing. A 90-day pilot is required if the iron filters would be removed from the water plant. If the iron filters remain, a pilot would not be required by the DNR. MSA will discuss the model and pilot testing with City staff later in February. If pilot testing is desired, we will move quickly to have that scheduled for this spring. Trail Connection between Roundabout and Parking Lot MSA completed the survey for this connection as part of the North Park Road project. The base map is complete and ready for design. A concept will be prepared illustration possible connections to the soccer field parking lots. This concept will be reviewed with City staff prior to commencing with final design.
