(CCI) are due October 29, 2021. Public Works Department would like to submit grant applications for bridges 60.5/49A and 34/17A. Bridge 60.5/49A crosses Lone Tree Creek about 2 miles east of the Airport on WCR60.5. This structure was constructed in 1967, is classified as structurally deficient, and has been defined as "poor" on the CDOT Off - System Structure Eligibility List. The total cost estimate for this bridge replacement is $8,500,000. The total available grant funds described in the CCI memo for this round of grant funding is only $5.3 million. Since there is not a lot of available grant funds, and the goal of CCI is to spread those funds amongst as many qualified applicants as possible, we are proposing to request a grant of $1,000,000 for this bridge replacement. The remainder of the estimated costs, $7,500,000, would be the County's contribution to the project (88%). This bridge would be our #1 priority for this grant funding since it is already included as a line item in our current 5 -year CIP. Bridge 34/I7A crosses Saint Vrain River about 2 miles west of Platteville on WCR34. This structure was constructed in 1960, is classified as structurally deficient, and has been defined as "poor" on the CDOT Off - System Structure Eligibility List. The total cost estimate for this bridge replacement is $13,400,000. For the reasons described above we are proposing to request a grant of $1,000,000 for this replacement. The remainder of the estimated costs, $12,400,000, would be the County's contribution to the project (93%). This bridge would be our #2 priority for this grant funding since it is less time critical than Bridge 60.5/49A. This bridge is included in our 5 -year CIP. What options exist for the Board? (include consequences, impacts, costs, etc. of options): Approve staff to move forward with both grant applications as shown above. o Potentially receive $2.0M in grant funds to offset estimated expenditures of $21.9M. Approve staff to move forward with one highest priority of the grant applications as shown above. o Potentially receive $1.0M in grant funds to offset estimated expenditures of $8.5M. • Change the amount of grant funding being requested and apply for one or both bridges. • Deny staff submitting for these grant funds for the replacement of these bridges. 2021-2968 10 ao aC900-19 Recommendation: Staff recommends applying for both projects and requesting $2.0M on the applications with the County contributing the remainder of the needed funds. Staff requests authorization to place these bridge grant applications on the BOCC Meeting Agenda prior to October 29th. Approve Perry L. Buck Mike Freeman Scott K.

The roadway would be closed during the construction which would likely take 9-10 months. The new bridge would be designed to meet current CDOT bridge design standards and current 100 -year flood elevations. Weld County would hire a qualified design consultant with extensive knowledge of the CDOT standards. Some new right-of-way acquisition would likely be required. Some utilities relocations would likely be required. Weld County would bid out the construction to a qualified general contractor.

BOX 758 GREELEY, COLORADO 80632 PHONE: (970) 400-3706 October 1, 2021 RE: Narrative for Bridge WEL060.5-049.0A (Fiscal Years 2022-2024 Funding) Bridge WEL060.5-049.0A is on Weld County Road 60.5 and spans the Lone Tree Creek. The bridge is located 0.7 miles east of WCR 49. WCR 60.5 is classified as a Collector Road and is a vital paved link for the County and the nearby communities of Greeley, Kersey, and Gill. Traffic counts taken in 2020 show an ADT of 1,684 vehicles per day, with 27% being trucks. This high percentage of trucks is likely accelerating the poor condition of this bridge. Replacement of this bridge is our number one priority for this bridge funds application period. The existing bridge is 34 feet wide, 165 feet long (three spans), and was built in 1967. It is structurally deficient and has been defined as "poor" on the Off -System Structure Eligibility List. The bridge has issues with rusted steel and spalling concrete on the substructure and superstructure. The bridge rail and approach guardrails are constructed improperly, in poor condition and do not meet current AASHTO/CDOT standards. Rehabilitation instead of replacement is not a viable option, nor cost effective, because of the concrete deck extensive degradation, rusted steel substructure elements, and age of the overall structure. The new structure may need to be elevated above its current configuration to allow for adequate freeboard to prevent debris collection and scour in future flood events. Weld County is proposing to provide most of the funding for this project due to the importance of this vital link for the area. Instead of the typical 20% funding match, Weld County is proposing that CDOT partner with Weld County on this project by providing a $1,000,000 grant from the available bridge replacement funds. We estimate the replacement cost at $8,500,000 with the Weld County portion being $7,500,000 (88%). Weld County currently has the necessary funds to cover our portion of this project.

Mike, I should be listed as the Local Agency Coordinator, not Bryce On the first page, I believe the proposed total local match amount should be the sum of the 20% minimum local match amount and the local overmatch amount. So, on the Lone Tree Creek application, that field should be 8,700,000 not 7,000,000. The cost estimates seem high, especially in comparison to the WCR 19 Bridge. Did you intentionally overestimate? Bryce may have more comments for you.

BOX 758 GREELEY, COLORADO 80632 PHONE: (970) 400-3706 October 1, 2021 RE: Narrative for Bridge WEL034.0-017.0A (Fiscal Years 2022-2024 Funding) Bridge WEL034.0-017.0A is on Weld County Road 34 and spans the Saint Vrain River. The bridge is located 2 miles west of Platteville. WCR 34 is classified as a Collector Road and is a vital paved road serving Weld County, Platteville, and the agricultural and oil/gas industries. Traffic counts taken in 2020 show an ADT of 1,363 vehicles per day, with 43% being trucks. This high percentage of trucks is likely accelerating the poor condition of this bridge. Replacement of this bridge is our number two priority for this bridge funds application period. The existing bridge is 30 feet wide, 294 feet long (six spans), and was built in 1960. It is structurally deficient and has been defined as "poor" on the Off -System Structure Eligibility List. The bridge has issues with rusted steel and spailing concrete on the substructure and superstructure. The bridge rail and approach guardrails are constructed improperly, in poor condition and do not meet current AASHTO/CDOT standards. Rehabilitation instead of replacement is not a viable option, nor cost effective, because of the rusted steel substructure elements, and age of the overall structure. The new structure may need to be elevated above its current configuration to allow for adequate freeboard to prevent debris collection and scour in future flood events. This bridge was badly impacted during the 2013 flood event and required extensive emergency repairs to put it back into service. Weld County is proposing to provide most of the funding for this project due to the importance of this bridge for the area. Instead of the typical 20% funding match, Weld County is proposing that CDOT partner with Weld County on this project by providing a $1,000,000 grant from the available bridge replacement grant funds. Using the CDOT guidelines we estimate the replacement cost at $13,400,000 with the Weld County portion being $12,400,000 (93%). Weld County currently has the necessary funds to cover our portion of this project.

Mike, I should be listed as the Local Agency Coordinator, not Bryce On the first page, I believe the proposed total local match amount should be the sum of the 20% minimum local match amount and the local overmatch amount. So, on the Lone Tree Creek application, that field should be 8,700,000 not 7,000,000. The cost estimates seem high, especially in comparison to the WCR 19 Bridge. Did you intentionally overestimate? Bryce may have more comments for you.
