Title
Consider a resolution authorizing the Mayor to execute Supplemental Agreement No.1 with Halff Associates, Inc. for the Heritage Trail West Project.
Body
This supplemental agreement is for engineering services associated with floodplain permitting. As the floodplain model was completed, it was determined that a CLOMR/LOMR would be since no-adverse impact could not be shown. Elements of the design, such as pedestrian underpasses under the Union Pacific railroad, as well as additional bridge columns have triggered the need for the CLOMR/LOMR at Heritage Trail West. In an effort to save the City money, flood models were run for the other portions of trail along Brushy Creek (Heritage Trail East and Brushy Creek Trail Georgetown to A.W. Grimes). It was determined that elements of design on those sections of trail would also trigger the need for the CLOMR/LOMR. As a result, the engineering required for the CLOMR/LOMR on those projects has also been included in this supplemental agreement. By rolling all three CLOMR/LOMR into one, it will save the City over $20,000. Additional items included in this supplemental agreement include structural engineering for an area of washout at the existing pedestrian bridge which has progressively gotten worse since the start of project. Finally, through project plan review, the stormwater division was able to suggest an alternative method to drain water which required additional surveying. The alternative method will ultimately save the City significantly during the construction phase of the project.
This project includes a 10' wide trail detailing the history of Round Rock as a timeline. The project spans from Bathing Beach at Chisholm Trail Road to Mays St and include improvements at Bathing Beach Park, Chisholm Trail Crossing Park, and Memorial Park. The programmatic elements of the project will include historical elements, educational elements, arts & cultural elements, general park elements and elements that e...
