1.0 STREAMBANK DAMAGE ASSESSMENT

1.1 Task Description

The Bella Vista Property Owners Association (POA) hired Burns & McDonnell to prepare a report with cost estimates to repair damage caused to the three golf courses by the recent flood events. The seven sites that were investigated and considered for repair are:

1. Site 1: Berksdale, East of Hwy. 71 Bridge

2. Site 2: Berksdale, Under Hwy. 71 Bridge

3. Site 3: Berksdale, West of Hwy. 71 Bridge

4. Site 4: Berksdale, East of the 18th Green

5. Site 5: Kingswood, Between the back tee of #18 and bridge from #17 green to the forward tee at #18

6. Site 6: Kingswood, West of the 4th Green

7. Site 7: Kingswood, Confluence with Lake Ann Tributary

These seven sites are shown on the maps to the right.

1.2 Cost Estimates

Burns and McDonnell performed a site visit at each location on October 9, 2017. During this visit, Burns & McDonnell staff met with a client representative. The client representative indicated that their preferred method of streambank protection is riprap due to its affordability and ease of construction Therefore, the estimates reflect riprap as the preferred alternative. An additional alternative is also included for the use of gabion baskets in locations where aesthetics is a concern. The cost estimates provided herein are based on previous streambank stabilization project information provided for use by the POA, Streambank and Shoreline Protection Manual, the Arkansas Department of Transportation (ArDOT) bid tabulations, and general knowledge and experience. The development of the cost estimates assumes that one site will be repaired at a time. Cost savings may be achieved if sites are repaired in groups. Additionally, the estimates do not include permitting costs for the Federal Emergency Management Agency (FEMA). FEMA approvals may not be necessary depending on the final approach taken to re-establish a stable streambank. The following page provides summary costs for the stabilization of each site. The detailed cost breakdown for each site is included in Appendix A.

2.0 BRIDGE REPLACEMENT

2.1 Task Description

Burns and McDonnell was also tasked with preparing cost estimates to replace five precast concrete beam bridges with steel arch truss bridges similar to the structure installed near Kingswood Hole #18. The five structures included in this analysis are listed and shown below. The approximate locations are shown in the figures below.

1. Berksdale Golf Course, Bridge Site 1 2. Berksdale Golf Course, Bridge Site 2 3. Berksdale Golf Course, Bridge Site 3 4. Berksdale Golf Course, Bridge Site 4 5. Kingswood Golf Course, Bridge Site 5

2.2 Cost Estimates

Burns and McDonnell performed a site visit at each location on October 9, 2017. At that time, bridges at Site 1 and Site 2 were both closed. Each of the five structures were multiple spans comprised of precast concrete beams supported on steel H-pile intermediate bents. Replacement structures are recommended to be single span weathering steel prefabricated arch truss bridges with concrete decks supported on steel H-pile concrete abutments with straight turnback wings. Each bridge should be designed to carry emergency vehicles and have a 12-foot minimum roadway width. The replacement structures should be designed to minimize maintenance requirements. Single span bridges will eliminate the build-up of drift debris against the bridge piers and weathering steel will avoid the need for regular painting. Using abutments with turnback wings will provide a high degree of bridge end protection during flood events.



Cost estimates to remove and replace the above listed bridge structures are provided herein. These estimates are based on costs associated with previous bridge replacements by the POA, prefabricated truss manufactures cost estimate to fabricate and deliver the new truss, ArDOT bid tabs and general knowledge and experience. Similar to the stream bank stabilization estimates, these cost estimates assume that one bridge will be replaced at a time. Cost savings may be achieved if bridges are replaced in groups. Additionally, the estimates do not include permitting costs with state or federal agencies such as the U.S. Army Corps of Engineers or Federal Emergency Management Agency (FEMA). The Site 5 estimate is the only location that includes costs for a CLOMR/LOMR approval from FEMA. This is because a new alignment is likely, and that process would be required for the work to be done. The new alignment will eliminate the sharp curve in the trail on the west end to allow the passage of emergency vehicles. The CLOMR/LOMR permitting process can increase costs of up to $35,000 to remap the floodplain. Options for avoiding the need for a CLOMR/LOMR can be explored for the other locations during the design and planning for construction. These options could include showing a “no-rise” during the floodplain modeling or closing the existing bridge and placing the new bridge in the same location as the existing. Specific to Site 2, the team was asked to consider the removal and abandonment of this bridge. This cost is estimated to be roughly $45,000. A summary of the bridge replacement costs is provided on the following page, and the detailed cost breakdown can be found in Appendix B.

*Per email conversation on February 20, 2018, The IBC code is what all building and parking garages are built to, and it allows for a more cost efficient design on pedestrian truss bridges. The IBC code could save an owner 10% to 15% on a bridge. The prices in the report were reduced from the above statement by roughly 15%.
