PROJECT DESCRIPTION:

Dayton Street 3^rd to 9^th Ave Utility Replacement 

This project provides for the replacement and rehabilitation of Stormwater, Sewer and Potable Water Utilities along with ADA ramp improvements at the intersections of Dayton and 6^th, 7^th, 8^th, and 9^th and the addition of the missing link of sidewalk on the south side of Dayton from 7^th to 8^th.

SCOPE:

·   Replace and upsize existing utilities on Dayton from 3^rd to 9^th including:

o   3800 feet  of Water Pipe replaced

o   4300 feet of Sewer Pipe replaced

o   3200 feet  of Storm Pipe replaced

·        ·  New sidewalk on the south side of Dayton between 7^th & 8^th.

·        ·  Dayton Street to be rebuilt and paved along project limits.

·        ·   Pedestrian curb ramps to be constructed to meet ADA standards.

·  Revise sidewalk/intersection geometry at Dayton and 6^th, 7^th, and 8^th, & 9^th.

BACKGROUND:

·        ·  Existing storm pipe system is undersized and causes flooding in the downtown area during heavy rainstorms.

·  Water and Sewer Pipes are at or near the end of their lifespan and are in need of upsizing and rehabilitation.

SCHEDULE:

·        ·  Estimated Design Completion end of 2018.

·        ·  Construction expected to start by early spring 2019.

·        ·  Construction expected to be divided by blocks/sections/areas.

· Starting at 3^rd & Dayton required due to Sewer and Storm pipes being gravity driven.

CONSTRUCTION SEQUENCE:

·        ·  Project divided in two phases (one in 2019 and one in 2020)

o   3^rd to 5^th +/- (Phase 1, Spring 2019 to Fall 2019)

§  Sewer pipe rehabilitation work between 6^th and 9^th may be part of phase 1.

o   5^th to 9^th (Phase 2, Spring 2020 to Fall 2020)

·        ·  Except for only a few days during the project 5^th & Dayton expected to remain open.

·        ·  Will look into possibility of work on certain Saturdays.

·        ·  Keeping roads open and making the block that is being built on one way.  Possible occasional one day intersection/block closures to through car traffic, especially between 3^rd and 6th.

§  One way/one lane shifting

·  Sidewalks will be accessible by foot traffic.

 TRAFFIC AND PEDESTRIAN IMPACTS:

·  Sidewalks will remain open except for temporary closures to protect pedestrians during construction activities.

·  Intersections may be closed for short durations (1-2 days) for vehicle and pedestrian safety.

·  Street segments under construction will have one-lane open to vehicle traffic.

·  Daytime construction activities may require flaggers and one-way traffic control.

COST:

 ·  Construction costs estimated to be $7 million.
