Table 4-13. Pages Branch Damage Reach Information n/a – not applicable * - information not available K – 1,000 dollars Richland Creek Watershed The Richland Creek Watershed is located in southwestern Davidson County. Richland Creek originates at an elevation of approximately 1,100 feet and flows in a north to northwesterly direction to an elevation of approximately 375 feet at its mouth. The watershed drains an area of 28.45 square miles and empties into the Cumberland River at river mile 175.6. The watershed is divided into 6 major sub-basins: Belle Meade, Vaughns Gap, Jocelyn Hollow, Sugartree, Middle, and Lower. There are five major tributaries that empty into Richland Creek Mainstem: Unnamed Tributary, Sugartree Creek, Jocelyn Hollow Branch, Vaughns Gap Branch, and Belle Meade Branch. The watershed is characterized by rugged topography in the southern portion and flat to gently sloping plains with local hills reaching between 300-800 feet in the central and northern portions. Richland Creek and its tributaries flow through predominately urban settings. Damage Reaches Nine damage reaches have been identified on Richland Creek and its tributaries (Appendix C, Figure C.11). Flooding problems in these areas are due to development and construction in the natural floodplain, aggravation due to upstream and local urbanization, and backwater created from multiple undersized bridges/culverts. Table 4-14 provides specific damage information for each reach. Damage Reaches 1 and 2 are located on Richland Creek Mainstem. Damage Reach 1 extends from 495 feet downstream from Briley Parkway to 3,240 feet upstream from Charlotte Pike. Damage Reach 2 is located between the upstream side of Bosley Springs Road and 120 feet upstream from Harding Place.

Damage Reaches 3 and 4 are located on Unnamed Tributary to Richland Creek. Damage Reach 3 extends from 325 feet upstream of Montgomery Bell Academy to 185 feet downstream of Bowling Avenue. Damage Reaches 5 and 6 are located on Sugartree Creek. Damage Reach 5 extends from 1140 feet downstream of Valley Forge Drive to a point 625 feet upstream of Estes Road. Damage Reach 6 is located between the upstream end of Damage Reach 5 and 280 feet downstream from Hillsboro Pike. Damage Reach 7 is located on Jocelyn Hollow Branch and extends from 116 feet upstream of the Seaboard Systems Railroad to a point 501 feet upstream of Sedberry Road. Damage Reach 8 is located on Vaughns Gap Branch and extends from the upstream side of the Memphis-Bristol Highway to a point 1025 feet downstream from Park Lane. Damage Reach 9 is located on Belle Meade Branch and extends from 622 feet downstream from Forsythe Place to 70 feet upstream from Warner Place.
