The Alaska Department of Transportation and Public Facilities (DOT&PF) has assumed the responsibilities of the Federal Highway Administration under 23 U.S.C. 327 and is soliciting comments and information on a proposal for preventative maintenance on nine bridges within Central Region (CR) as part of the annual preservation activities program. The purpose of the proposed project is to improve safety and increase the lifespan of bridges. Work would be limited to the approaches, decks, abutments, drainages, and piers of bridges located within the Municipality of Anchorage, Kenai Peninsula Borough, and Matanuska-Susitna Borough.
This project would involve floodplain encroachments – refer to the table below for details. A flood hazard development permit would be obtained for all work within a flood zone or floodway, as required by code in each borough.
| Bridge | Bridge No. | FEMA Flood Insurance Rate Map | Work Details | Flood Zone |
| Ship Creek | 1320 | 02000050752D | Deck overlay and bearing restoration - no in-water work | Ship Creek is designated as a Zone AE floodplain and a regulatory floodway |
| David Douthit Veterans Memorial | 0671 | 02122C0905F | Joint repair and abutment back wall repair - no in-water work | The Kenai River is designated as a Zone AE floodplainand a regulatory floodway |
| Seward Meridian Undercrossing | 1989 | 02170C8105F | Joint Repair, spall repair, and concrete repair - no in-water work | None |
| Stariski Creek | 0667 | 02122C1885E | Deck overlay - no in-water work | Zone D floodplain |
| East Fork Sixmile Creek | 0615 | 0200121475A - not printed | Deck overlay, abutment back wall repair, and debris removal from Six Mile Creek (logs) | None |
| Granite Creek | 0616 | 0200121475A - not printed | Deck overlay and sediment removal to re-establish as-built conditions - no in-water work | None |
| Hicks Creek | 0547 | 020021 (unmapped) | Approach slab repair - no in-water work | None |
| Deep Creek | 0668 | 02122C1620E | Joint repair, fill in gap under abutment cap, and debris removal in creek (logs) | Zone D floodplain |
| Little Susitna River | 0240 | 02170C7143F | Deck asphalt repair and debris removal in the creek (logs) | The Little Susitna River is designated as a Zone AE floodplain and a regulatory floodway |
DOT&PF Maintenance & Operations personnel plan to conduct the work in 2027. Only debris removal work in East Fork Sixmile Creek, Deep Creek, and the Little Susitna River would be below Ordinary High Water (OHW).
The encroachments are expected to be minor, with no net changes to the base flood elevation, thus the work would not result in a significant encroachment. Additionally, no longitudinal encroachments are anticipated.
This proposed project will comply with Section 106 of the National Historic Preservation Act; Executive Orders: 11990 (Wetlands Protection), 11988 (Floodplain Protection), the Clean Air Act, Clean Water Act, Fish and Wildlife Coordination Act, and U.S. DOT Act Section 4(f).
