Hollywood-Grant Park Phase 2 Sewer Repair Project

Updated May 30, 2019Button. Click to sign up for email updates

Environmental Services is designing and constructing a sewer improvement project to repair or replace 3,000 feet of aging public sewer pipes that are in deteriorating condition. These pipes were originally part of the Hollywood-Grant Park Sewer Repair Project but were removed from that project due to the complexity of work in sewer easements on private properties. They have now been added to the Montavilla North Sewer Repair Project, which is currently in construction. The project also includes repair and construction of manholes, sewer access cleanouts, and 196 feet of sewer service laterals. This work on private properties is being referred to as Hollywood-Grant Park Phase 2. These improvements will protect public health and the environment by reducing the possibility of sewage releases to buildings and streets.

The City's contractor for the Montavilla North Sewer Repair Project, Landis & Landis Construction, will complete the public sewer repair and reconstruction work for the Hollywood-Grant Park Phase 2 Sewer Repair Project.

Location

The project will repair or reconstruct public sewer pipes, manholes, cleanouts, and sewer service laterals at locations illustrated on the map below.

Project Map

General Schedule

Construction on private properties for Hollywood-Grant Park Phase 2 is anticipated to occur this summer. The construction schedule is being coordinated with the larger Montavilla North Sewer Repair Project schedule.

General work hours will be 7 a.m. to 6 p.m., Monday through Friday, and Saturday if needed.

Look-ahead Schedule

Between this week and June 7, the contractor is scheduled to work at several locations. The schedule may change due to a variety of factors, including weather, conditions underground, availability of materials and labor, and other factors.

Open trench excavation to replace main line public sewer pipes and boring to repair service laterals to adjacent properties are scheduled to occur at the following locations:

  • NE Wistaria Drive east of NE 38th – Mainline pipe June 3-4, laterals June 5-6
  • NE Cesar E. Chavez Blvd north of Stanton St – Laterals June 5-6

Construction Methods

The contractor will use a combination of open trench and trenchless methods to repair and reconstruct the public sewer pipes, manholes, cleanouts, and sewer service laterals. The methods will vary from property to property depending on many factors, including pipe conditions, soils, slope, access challenges, and other conditions.

In locations requiring Sewer Boring, it will be necessary to dig a sending pit and a receiving pit to install the pipes. Crews will then drill a hole underground between two points without disturbing the surface between sending and receiving pits and install the new sewer line.

In locations requiring Open Trench Excavation, it will be necessary to dig a trench to install the pipes. Crews will then reconnect sewer service laterals that provide sewer service to adjacent properties. After sewer construction, crews will backfill the trenches and apply a new layer of topsoil and grass seed. For more details and photos about the open trench excavation construction method, click here.

In locations requiring Pipebursting, it will be necessary to dig a sending pit and a receiving pit to install the pipes. Crews will insert a bursting head into the pit to shatter the existing pipe and force pipe segments into the surrounding soil. Crews will then pull or push new pipe into place behind the bursting head. Crews will then reconnect sewer service laterals that provide sewer service to adjacent properties. After sewer construction, crews will backfill the pits and apply a new layer of topsoil and grass seed. For more details and photos about the pipebursting construction method, click here.

In locations requiring Cured-In-Place-Pipe Lining (CIPP), crews will access the sewer pipes through manholes. Working from a manhole, crews will insert a flexible liner inside the old pipe. Crews then inflate the liner and use hot water, steam, or ultraviolet light to cure the liner, forming a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. Crews will then reconnect sewer service laterals that provide sewer service to adjacent properties. For more details and photos about the CIPP construction method, click here.
