Infrastructure Modernization: Replacing aging 30-inch and 36-inch storm sewers with a single 60-inch pipe to enhance stormwater conveyance capacity and flood resilience.

Integrated System Design: Coordinating stormwater and sanitary sewer improvements to streamline construction, reduce disruption, and improve overall system efficiency.

Flood Mitigation & Water Storage: Redefining site contours and adding a control structure to create dual connected storage areas for increased stormwater detention.

Collaborative Project Delivery: Joint efforts with SD1 and the Phase II consultant ensure a unified approach to system upgrades and connection coordination.

Environmental Stewardship: Opportunity to secure full environmental permitting from USACE and KDOW, supporting compliance and sustainability goals.

Complex Utility Coordination: Replacing and upsizing both stormwater and sanitary systems simultaneously required close coordination with SD1 and multiple project stakeholders.

Permitting & Regulatory Compliance: Meeting the requirements of federal and state environmental agencies added scheduling and documentation complexity.

Construction Impact Management: Minimizing disruption in a developed corridor while managing large-diameter pipe installations demanded strategic planning and sequencing.

Design Integration: Aligning hydraulic, geotechnical, and environmental components into one efficient, constructible design.

Comprehensive Engineering Services: Palmer provided full-scope support—from data review and stormwater modeling to construction documents, easement coordination, and permitting.

Efficient System Enhancement: New 60-inch storm sewer and 21-inch sanitary sewer designs significantly improve conveyance capacity, reduce flood risk, and support long-term community infrastructure needs.

Regulatory Readiness: All permits, including those from USACE and KDOW, were successfully prepared and submitted in compliance with environmental standards.

Stakeholder Collaboration: Seamless coordination among SD1, property owners, and consulting teams ensured a smooth path to construction.

Ready for Implementation: The project is fully designed and permitted, awaiting SD1’s final approval to move into construction—demonstrating Palmer’s commitment to timely, compliant, and high-quality project delivery.
