Marion Street Storm System

MARION STREET STORM SYSTEM PROJECT

 
 
 

Background

The purpose of this project is to further address significant historical flooding areas in the Whittier, Five Points and City Park West neighborhoods. This phase of the project will connect into the recently completed 33rd Street Outfall project, at the intersection of MLK Jr Boulevard and Marion Street. Future phases will extend this storm sewer infrastructure south to the intersection of 21st Avenue and Downing Street, where it will tie into, and relieve, an overburdened existing 84” storm sewer system. 

General Information

This project will install new 8’ x 8’ Reinforced Concrete Box Culvert in Marion Street to the intersection with 27th Avenue. 

In addition to installing the new 8’ x 8’ storm sewer infrastructure, the Marion Street System project will:

  • Install new storm inlets and manholes
  • Install new water quality features to reduce trash/debris from entering into the storm sewer system
  • Install new ADA compliant pedestrian ramps at all intersections
  • Upgrade existing curb cuts to be compliant with City of Denver transportation standards
  • Relocate and install new Denver Water main lines
  • Replace Denver Water lead service lines with new copper lines from the new water main to the property owners’ meter
  • Provide new bike lane at East Whittier Island Park
  • Reshape Marion Street to provide greater surface water storm runoff capacity
  • Provide new full depth paving on Marion Street

Project Status

Project Start: Construction is expected to begin in July 2020, with completion anticipated in March / April 2021. These dates may be pushed out a few weeks if there are unforeseen COVID-19 impacts.

Important Status Update: Because of some materials specification changes by Denver Water, and the procurement lead time for those materials, we are going to have to move our mobilization and start date back by one week. Crews will now begin to mobilize the week of August 3rd—with the initial closure beginning then—and work will start the week of August 10th. 

Estimated Completion Date: March 2021

Future Phases: Dates TBD


Council District: 9

Neighborhoods: Whittier, Cole, Curtis Park, Five Points

Construction Methods, Impacts and Detours

 

Pre-Construction Update - 8/14/20

Status: Work on water services is underway. This work is not affecting residents at this time. Next week will bring very short, approximately 5-minute-long outages along Marion — from MLK to 31st — as the service changeovers are made. Those affected will be contacted in person by the contractor.  You will begin to see heavy equipment moving onto the site as work on the base slab of the transition structure begins, on Marion near MLK. This transition structure ties into where the 33rd Street stormwater project ended.

Trash Service: As the project progresses, we will be in touch with residents regarding trash service along Marion. You will be contacted with trash placement instructions prior to any impacts.

Impacts: The intersection of 31st and Marion — as well as the whole block of Marion between MLK and 31st — will be closed for approximately 3-4 months. 

Resident Parking: During this first segment of construction — on Marion between MLK and 31st — the 2-hour parking spots on both the north and south sides of 31st Ave (between Downing and the Alley) have been replaced with designated “Resident Only” parking signs to help with neighborhood parking. Similar signage east of the project, between the alley and Lafayette St., is in place. Parking will be available on Marion Street, between 31st and 30th, but that block will only be accessible from the south. See the parking areas noted on the map above. 

RTD Route Change for EB 43: Please note this route change for RTD EB 43. Coming from Stout, the bus will now turn left on Downing, right on Bruce Randolph, right on Williams, left on 31st and will then proceed to regular route. If you have any questions about route changes, please visit www.rtd-denver.com.

PLEASE NOTE: Homeowners within a 250-foot radius of the construction area will be receiving letters from Integrated Geotechnical Solutions (IGS) offering an inspection of their home prior to start of construction.
