10-Preferred Alternative-Phase 5.pdf

This document is a Preferred Alternative analysis prepared for the Waukesha County Department of Public Works in support of the CTH K Corridor modernization and expansion project spanning the Villages of Sussex, Lisbon, Menomonee Falls and the City of Brookfield in Wisconsin. The file presents Phase 5 of the project development process, which focuses on identifying and evaluating alternative design concepts for the corridor improvement between CTH JK and Brookfield Road. The document outlines various design alternatives, including alignment options, cross-sectional configurations, and intersection treatments, with detailed comparative analysis of each alternative's advantages and disadvantages. The preferred alternative presented represents the recommended design approach based on engineering evaluation, environmental considerations, and community input. The analysis includes preliminary cost estimates, traffic impact assessments, and preliminary environmental impact assessments to support the selection of the preferred design direction for advancing into detailed design and permitting phases.

The Preferred Alternative Phase 5 document serves as a critical deliverable in the facility development process that will ultimately result in the preparation of preliminary and final plans, PS&E documents, and supporting reports necessary for project construction. This analysis reflects the engineering design services being procured through the RFQ process and represents the foundational work required prior to final design development. The document incorporates considerations for utility coordination, drainage requirements, right-of-way impacts, and compliance with applicable design standards and regulations. The preferred alternative selection documented herein provides the basis for the next phase of consultant services, enabling the design team to proceed with detailed engineering, permitting, and PS&E preparation activities required to support the federal funding program for Phase 1 of the corridor expansion project.
