Realignment – Project Update on Additional Work to Realign City Watermain
SUBMITTED BY: Jack Griffin, City Engineer
REVIEWED BY: Kristina Handt, City Administrator
Rob Weldon, Public Works Director
Chad Isakson, Assistant City Engineer
ISSUE BEFORE COUNCIL: Should the City Council receive a project update and provide
feedback/direction to staff in regards to the need to realign the city owned watermain in Washington County
right-of-way in conflict with county facilities being constructed as a part of the Manning Avenue North
(CSAH 15) and Stillwater Boulevard (CSAH 14) Realignment project?
BACKGROUND, PROPOSAL DETAILS/ANALYSIS: The City of Lake Elmo owns a 12-inch
watermain which runs along the north side of CSAH 14 between 39th Street and Little Blue Stem Trail
North within Washington County right-of-way. Field review of the existing watermain route and proposed
infrastructure being built as a part of the project shows the watermain is in conflict with future drainage
basin facilities and requires approximately 1,000 feet of watermain to be relocated.
Staff is working with the county and their design engineers to complete a detailed design of the relocation
and soliciting pricing from the contractor to complete the work. This agenda report is intended to inform
the Council of the issue. Additionally, as a part of the watermain relocation, the City will be providing
water service stubs to the 4 residential properties and 1 commercial property shown on the attached exhibit.
Under current City policy, these properties are not required to connect to City water but will have the option
to connect as they deem appropriate.
The watermain was installed in 2002 as part of the Fields in St. Croix development using directional drilling
and passes beneath two Northern Natural Gas mains. The pipe was therefore installed using HDPE pipe at
depths up to 15-feet and using no ductile iron pipe fittings. The watermain is therefore very difficult to
locate and the record drawings are not reflective of the project as constructed.
FISCAL IMPACT: Costs are unknown at this time. Staff will provide an estimate once the relocation
design is complete and the contractor has provided pricing for the work. Washington County has stated that
they believe the relocation construction costs should be the City’s responsibility, similar to the City
requiring Xcel Energy to relocate utilities found in City right-of-way.
RECOMMENDATION: Staff is recommending that the City Council receive a staff update and provide
any feedback/direction as deemed appropriate in regards to the work to realign the City owned watermain
in Washington County right-of-way as a part of the Manning Avenue North (CSAH 15) and Stillwater
Boulevard (CSAH 14) Realignment project.
