Action Requested: Item 4K: Approve an engineering services agreement with VRX, Inc. (VRX) to provide engineering design services for erosion protection at Dove Creek near E Highland Street in an amount not to exceed $150,000. Item 4L: Approve an engineering services agreement with VRX, Inc. (VRX) to provide engineering design services for erosion protection at Big Bear Creek near Timber Court in an amount not to exceed $135,000. Background Information: The purpose of Items 4K-4L is to approve engineering services agreements with VRX to address areas of concern where sanitary sewer infrastructure is exposed due to erosion and could be compromised for failure. In FY 2022, staff requested a new project in the Capital Improvements Program to implement permanent erosion control along creek and stream banks, restore sanitary sewer manholes to their previous state, and protect the City's critical infrastructure, and to prevent environmental impacts that may result from infrastructure failure. The locations of these improvements are a result of routine field inspections performed in areas of concern identified by previous studies, record drawings, and topographical information. The project locations of these improvements include Dove Creek near E Highland Street in the Milner and Hall No. 687 Additions, and Item 4K — Item 4L Big Bear Creek near Timber Court in the Continental Park Estates Addition. While the projects are similar in nature, cost variations arise from differences in the level of design efforts from each project location. Although these are smaller projects from a construction cost standpoint, the level of effort required for the regulatory and modeling services are equivalent to larger restoration projects. Each project location agreement includes a contingency for unforeseen changes to the project scope that would be deemed necessary. In addition to basic design and surveying services, each project contains additional special services including regulatory (floodplain, environmental and cultural resources) review and permitting, hydraulic modeling, easement services, public coordination and meetings, bidding, and construction phase services. These special services identified in each agreement will require authorization from City staff to complete. Financial Considerations: Funding for these agreements are budgeted as part of the approved Capital Improvement Program. Each agreement is within the project budget. Below are the itemized expenses for each project location and its continaencv: Item Project Location Design Cost Design Contingency Total Cost 4K Dove Creek near $137,220 $12,780 $150,000 E Highland Street Big Bear Creek 4L near Timber $121,036 $13,964 $135,000 Court Strategic Link: These items link to the City's Strategy Map strategic focus areas of Safety & Security, Infrastructure, and Performance Management & Service Delivery.
