A hydraulic model was developed to reflect existing conditions along the F101 Channel which serves as an outfall for drainage from the Battleground Estates Addition. The model indicated that flows within segments of the F101 Channel, north of North ‘P’ Street, rise to a level creating capacity limitations which produce frequent out of banks occurrences. The unimproved upstream channel flows into two forty-two inch (42”) corrugated metal pipes (CMP), which feed into the improved two 8’ x 10’ reinforced concrete boxes downstream. The difference in upstream and downstream conveyance areas creates a restriction upstream, leading to the increase water levels within the northern section of the channel. LJA Engineering, Inc. provided Engineering Design Services (FY 12-13) for the recommended improvements of removing the two upstream forty-two inch (42”) corrugated metal pipes and extending the dual 8’ x 10’ reinforced concrete boxes across North ‘P’ Street.
