BACKGROUND INFORMATION:
• The City of McKinney Engineering Department has identified a need for intersection capacity improvements at US 380 and Community Avenue including the addition of additional turn lanes and traffic flow improvements.
• These intersection capacity improvements have been included in the FY22 Capital Improvement Plan budget for CIP Project ST2011 including:
o $800,000 in collected roadway impact fees eligible for use in improving intersection capacity.
o $1,200,000 in grant funding approved under the NCTCOG Congestion Mitigation and Air Quality Improvement Program (CMAQ).
• The scope of improvements under this project include:
o Conversion of a single westbound left-turn lane on US 380 to dual left-turn lanes.
o Conversion of a single eastbound left-turn lane on US 380 to dual left-turn lanes.
o Construction of a westbound right-turn lane on US 380.
o Reconstruction of the eastbound right-turn lane on US 380.
o Conversion of a single southbound left-turn lane on Community Avenue to dual left-turn lanes.
o Associated paving, drainage, grading, lighting, and sign/marking modifications at the intersection to accommodate the improvements.
• Due to the grant funding associated with this project and the improvements being primarily located on a TxDOT roadway, additional design phase services will be required including meeting TxDOT design specifications, conducting environmental approvals, public involvement, and meeting special bidding and construction permitting requirements.
• Johnson, Mirmiran & Thompson, Inc. submitted a response to RFQ 21-41 for On-Call Roadway Design Services. They were one of eleven firms shortlisted by City Council on September 7, 2021.

• Design of this project is anticipated to take approximately 1 year to complete with construction estimated to begin in March 2023.
FINANCIAL SUMMARY:
• This Resolution authorizes a design contract and any necessary supplemental agreements with Johnson, Mirmiran & Thompson, Inc. for an amount not to exceed $430,000.
• Funds are available in the Capital Improvements Program Project ST2011.
