Piney Creek Reach #7 – Stream Reclamation Project

The Liverpool Metro District (LMD) Board and project sponsors Southeast Metro Stormwater Authority (SEMSWA), Urban Drainage and Flood Control District (UDFCD), and Cherry Creek Basin Water Quality Authority (CCBWQA) are proud to announce the start of the Piney Creek Reach 7 Stream Reclamation Project!

The project has begun with the installation of temporary construction fencing along Arapahoe Road and around the perimeter of the project site, which will block off access to the construction area from the south. Additional fencing will be added along the walkway between the creek and the homes on South Killarney Court and East Euclid Drive. This will close access to the construction site from the north. A temporary pipeline is being installed through the project site to pump and divert the creek for the duration of the project, to help expedite work required to stabilize the creek bed. Once all barriers are in place, a temporary construction access road from Liverpool Street will be installed near the fence line. The road will cross a section of concrete path and a gravel detour path and signage for trail users is being installed. We ask residents, for your safety, to be mindful of signage and we encourage the use of detours to avoid areas where construction vehicle traffic is present.

We understand this project will limit our resident’s use of the Piney Creek Open Space within the LMD. We will be working closely with SEMSWA to ensure the project moves quickly and efficiently and impacts homeowners as little as possible. Actual project construction of the channel will begin in early January is slated to wrap up in May or June 2017. Work will occur Monday through Friday from 7:00 am to 5:00 pm and Saturday 8:00 am to 5:00 pm. We ask that any residents with questions or concerns contact Kim Herman (representing the LMD) at 303-265-7923 or Kim.Herman@claconnect.com or Molly Trujillo (representing SEMSWA) at 303-858-8844 or mtrujillo@semswa.org.

As a reminder, this project will stabilize the Piney Creek Reach 7 to prevent stream and bank erosion and return the sediment transport to a balanced condition. The project will prevent further stream erosion, establish a natural function of the creek, increase water quality and habitat, improve safety, and avoid additional impacts to adjacent property owners by maintaining the floodplain limits.

Stream Reclamation Project Update

NOW-2015-01450-DEN – 7/18/2016: The District Engineer, U.S. Army Engineer District, Omaha Nebraska is evaluating a Department of Army Section 404 Permit application from Urban Drainage and Flood Control District, 2480 West 26th Avenue, Suite 156B, Denver CO 80211. Permits are issued under Section 404 of the Clean Water Act (Section 404) which regulates the placement of dredged or fill material in the nation’s waters. Urban Drainage and Flood Control District is proposing various activities to maintain existing flood conveyance and to restore the channel corridor by implementing a stream system with a length, pattern and profile that is geomorphically appropriate for its valley. This would result in increased stream stability through the restoration reach. Please click on this link to review the notification document: http://www.nwo.usace.army.mil/Media/Public-Notices/


Pond Restoration Project

The Liverpool Metropolitan District Board of Directors is planning to restore the 1.1 acre Greenfield Subdivision Pond beginning in 2014.

The Greenfield Subdivision Pond was designed and built to have an average depth of 4.5 feet with a maximum depth of 6 feet. Over the years the pond has accumulated a large amount of sediment, likely due to development within the general area. The current average depth today is 1.9 feet with a maximum depth of 5.7 feet.

The Liverpool Metropolitan District plans to remove approximately 3,600 cubic yards of sediment from the pond. In addition, the pond’s aeration system and fishing piers will be replaced along with developing fish spawning areas and beds.

This project is an effort to ensure and protect the long-term health and viability of the pond and its associated plant, fish and wildlife.
