9-Preferred Alternative-Phase 4.pdf

This is a project description document for engineering and design services prepared by the Waukesha County Department of Public Works for the CTH K Corridor modernization and expansion project spanning the Villages of Sussex, Lisbon, Menomonee Falls, and the City of Brookfield in Wisconsin. The document outlines the preferred alternative for Phase 4 of the corridor development, which follows the previously approved Phase 1 (Executive Drive to Sussex Creek). The project scope encompasses design and preparation of preliminary and final plans, PS&E documents, and supporting reports necessary for the modernization and expansion of CTH K between CTH JK and Brookfield Road. The consulting firm selected through the related RFQ will be responsible for the complete facility development process, with Phase 4 representing a subsequent phase of the overall corridor improvement initiative.

The preferred alternative analysis presented in this document evaluates design options and engineering considerations for Phase 4 implementation. This analysis supports the technical evaluation criteria used in the consultant selection process and provides the foundation for subsequent design phases. The document demonstrates that Waukesha County has secured federal funding approval for Phase 1, with the expectation that additional phases, including Phase 4, will proceed through similar planning and funding approval processes. The preferred alternative documentation serves as a critical planning tool to guide the selected consultant's work scope and technical direction throughout the design development phase.
