Body
BACKGROUND
On August 10, 2022, the City Council authorized a professional services contract with Pacheco Koch Consulting Engineers, LLC dba Pacheco Koch, a Westwood Company, for the engineering evaluation and design of storm drainage and erosion control improvements at four locations. Initial engineering services for the Cedar Creek Bridge at Moore Street included a preliminary design report to determine potential drainage improvement alternatives. A preferred alternative was selected, and it is now necessary to complete the design, prepare construction plans, and provide construction phase services. The existing bridge at Moore Street over Cedar Creek has a level of service that is less than the 10-year storm event. The proposed improvements consist of replacing the bridge so that the deck is raised above the 100-year storm elevation and the construction of retaining walls to support the embankment.
Additional engineering services are also necessary at two locations for proposed erosion control improvements. Easement documents will be prepared for 2412 West Kiest Boulevard and 3445, 3449, 3605, and 3621 Holliday Road to allow for the construction of proposed erosion control improvements. The improvements will stabilize the existing stream banks and address severe erosion at these locations.
This action will authorize a sSupplemental aAgreement No. 1 to the professional services contract with Pacheco Kock Consulting Engineers, LLC dba Pacheco Koch, a Westwood Company to provide additional engineering services necessary for developing construction plans and specifications and performing construction administration services for the Cedar Creek Bridge replacement at Moore Street and the preparation of additional easement documents for erosion control improvements at 2412 West Kiest Boulevard and 3445, 3449, 3605, and 3621 Holliday Road. The services provided include project management, survey, easement document preparation, subsurface utility exploration, geotechnical investigations, structural analysis, hydrological/hydraulic analyses, and engineering design.
