The Schertz Forest subdivision, comprising Robin Hood Way; Sherlock Lane; Nottingshire; Maid Marion; Will Cloudesley and Guy Guisborne was originally part of the 2024 SPAM project.  Most of the streets were in the resurfacing project, while a portion of Robin Hood Way and Sherlock were in the rehabilitation project.  As the project design was being completed, the project was removed from the SPAM project because the water line in Robin Hood Way, Sherlock Lane, and Nottingshire (the main "loop" through the subdivision) needs to be replaced and up-sized.  Staff decided to combine the water line replacement with the street work, much like was done for the Buffalo Valley South project.  This requires a new Task Order for one of our on-call Engineering Firms to add the water line replacement work to the planned street work to create the full, new project.  Kimley-Horn was selected as the on-call firm to complete this task as they did the design for the street work and already had some survey data needed for the water line replacement.

As Kimley-Horn was re-visiting the project area to prepare a scope and fee proposal for the water line replacement, they noted that the rehabilitation section had deteriorated significantly and the curb lines had settled/moved since their last site visit.  This rapid deterioration appears to be due to poor drainage in these street segments.  Additionally, the moving curb has increased the drainage issues to some degree.  The rehabilitation sections will now need reconstruction to also replace the curbs and to improve drainage in this area.  Kimley-Horn has included some additional design effort in the scope and fee for this Task Order to add in reconstruction of these street segments to the project effort.

With approval of the Task Order, Kimley-Horn will immediately proceed with the water line replacement design and the design modifications to the street work.  Staff anticipates construction will begin in Late Summer.

Have Council authorize the City Manager to execute the Task Order for water line replacement design and street reconstruction modifications and bid package for the Schertz Forest Subdivision.

Replacement of the water line will add additional flow capacity in the water system in Schertz Forest area, increasing the fire flow capabilities of the water system.  The planned street work will perform repairs and provide a new driving surface to most of the streets in the subdivision.  The resurfacing effort will "reset" the streets to a high PCI score and preserve them.  A couple of street segments will be reconstructed to improve drainage and help preserve the pavement life.  The street improvements will also improve the ride quality of the streets for the residents.

Approval of the Task Order for Kimley-Horn and Associates Inc. for $691,016.56 and a not to exceed amount of $720,000.00 for the Schertz Forest Roadway and Waterline Improvements project. The on call contract with Kimley-Horn and Associates has not yet been executed. As such, staff will not execute the Task Order until the on call contract has been executed. 

Funding for the Task Order is available from Water Impact Fees and Bonds.  The street work and the water line replacement work are both in the approved CIP, although as separate projects. The bonds plan to be issued this August for the 2025 projects.
