1.4. Lake Elmo Elementary School
This intersection improvement project is prompted by a land-use change adjacent to the intersection.
Stillwater Area Public Schools ("the school district") is finishing construction of a new site for Lake Elmo
Elementary School in the northwest quadrant of this intersection. The new school site will accommodate
approximately 1,100 students and 130 staff members. The school district is on track to receive approval for
building occupancy and commence school operations for the 2026-2027 school year by the beginning of
August 2026. There are two new access points onto County facilities due to school construction, which are
shown in Appendix B.
* Main School Access: Located along CSAH 10, approximately 1,225 feet west of CSAH 10/CSAH 17/CR
17B intersection; this access will be the primary access for staff/visitor parking and will also serve
parent pick-up/drop-off operations.
* Bus Access: Located along CSAH 17, approximately 1,250 feet north of the CSAH 10/CSAH 17/CR 17B
intersection; this access is intended for buses/utility vehicles only for the school.
Through the school site's development approval process, Washington County required a permanent traffic
signal system at the main school access on CSAH 10, a temporary (wooden pole) traffic signal system at the
intersection of CSAH 10/CSAH 17/CR 17B, and infrastructure for controlled access at the bus access to be
constructed in time for the start of school operations. All of these improvements to the County system have
been completed as of the posting of this solicitation.
1.5. Previous Project Phase
The design for both traffic signal systems along CSAH 10 was led by Washington County outside of this
project. The traffic signal system construction was constructed by the school district's contractor and
administered by the school district's construction manager. The final traffic signal system design plans will
be provided to the selected Consultant.
Washington County solicited a consultant for community engagement and preliminary design services in
April 2025. The deliverables for the preliminary design phase were to facilitate a comprehensive public
involvement plan to solicit community engagement regarding a robust alternatives analysis process, finalize
a community-supported preferred alternative (a draft concept layout is included as Appendix C), and
procure 60% (preliminary) plans and a 60% cost estimate. Thirteen (13) Project Management Team (PMT)
meetings occurred during the previous project phase. Washington County anticipates facilitating a formal
resolution of support to enter into final design from Lake Elmo City Council before the final design
consultant contract is awarded. The community engagement and preliminary design phase is anticipated to
be complete by Fall 2026.

1.6. Goals and Objectives for Current Project Phase
The objective of this phase of the project is to perform detailed engineering to produce accurate
construction documents for bidding. In summary, the goals of this project phase are as follows:
* Transition to final design efficiently utilizing the community engagement and technical progress
performed during the previous project phase
* Produce construction documents that meet applicable MnDOT, CSAH, Washington County and City of
Lake Elmo requirements.
* Produce accurate project cost estimates reflective of the proposed improvements.
* Design stormwater management in accordance with applicable regulatory requirements and the
previously coordinated stormwater treatment on the school site.
* Confirm the location of existing public and private utility facilities and coordinate required adjustments.
* Meet a final design schedule that prioritizes a favorable bidding environment in early 2028.
* Obtain/support the County in obtaining required permits from necessary permitting authorities.
* Develop a construction schedule and detour plans that are supported by the Project Management Team
(PMT) and balance construction operations efficiency with minimizing public inconvenience.
* Support the County's pre-construction communications to keep adjacent property owners, area
businesses, and the traveling public informed of the project team's plan for construction staging.
