This stretch of Ellerbe Creek exhibited typical urban stream problems associated with past channelization efforts by USACE, increased stormwater runoff, and loss of streamside vegetation. The degraded stream was characterized by excess sediment loading (from slumping, eroding banks), deep entrenchment, and poor aquatic habitat. In addition, Ellerbe Creek was an EPA 303d-listed stream due to its overall degraded water quality. EEP completed the construction phase of the restoration in March 2005. Following the natural channel design approach, the restoration increased channel sinuosity, established a floodplain bench, stabilized the banks, improved channel bed profile, and re-established a vegetated riparian buffer. The goals & objectives of the restoration project focused on improving water quality, enhancing flood attenuation, and restoring aquatic habitat and the riparian buffer. Successful completion of this project, coupled with other restoration efforts in the watershed, will help achieve these goals on a broader, watershed-wide level. Project Goals: • Provide a stable stream channel • Improve water quality • Reestablish the stream's capacity to efficiently transport watershed flows • Reconnect the stream a new floodplain at a lower elevation • Improve aquatic & terrestrial habitat and biological integrity of the system • Incorporate stormwater BMPs to treat urban runoff into the stream • Establish riparian zone using native vegetation Status of Project: 2.d Year Monitoring (Construction completed in March 2005) Post-construction Restoration Pre-construction Conditions • ? 0 Vegetation Plot Coordinates: Hillsborough Reach Plot Side HB-V1 HB-V2 H13-V3 Pin Coordinate E20115741.5610 E20116120.1110 E 2016551.0870 N 827358.3480 N 827428.6750 N 827505.1970 A 19.5' 31.1' 31.9' B 52.1' 35.4' 32.6' C 232' 33.1' 31.3' D 53' 36.2' 39.4' HB1L 2015742.0022 827332.7693 HB1R 2015772.552 827290.9634 HB2L 2015799.2852 827350.0513 HB2R 2015803.356 827295.5714 HB3L 2016595.6390 827499.8180 HB3R 2016610.0550 827433.3600 HB4L 2015654.5640 827499.8920 HB4R 20116634.3500 827432.4490 CR1L 2016939.2680 827570.7490 CR1R 2016915.6680 827552.4340 CR2L 2016957.7640 827541.2870 CR2R 2016933.5100 827520.8490 Photopoints HB-P1 2015577.0052 827347.3258 HB-P2 2015623.7143 827314.4264 HB-P3 2015802.5285 827349.0571 HB-P4 2015961.3634 827401.3361 HB-P5 2016127.5574 827481.3197 HB-P6&P7 2016301.8430 827496.7037 HB-P8 2016523.1130 827464.0709 HB-P9 2016749.2114 827430.4392 HB-P10 2016966.4524 827439.7628 C R-P1 2016781.3114 828053.9579 CR-P2 2016818.9390 827855.0313 C R-P3 2016919.4678 827582.3480 1400 1000 1200 11100 1050 11150 1300 1250 '1350 Vegetation Plot Coordinates: Croasdaile Reach Plot Side CR-V1 CR-V2 Pin Coordinate E 2016811.8250 E 2016933.510 N 827741.1850 N 827520.8490 A 32.4' 18.3' B 33.2' 65.5' C 29.9' 21.7' D 31.9' 64.1' PfQa- D4p Ogp4 D°p4 D°p-0 P4 D oD 4 P4 D 4. 1> O P p 4 q° 13 [> 3 1> O°°O ?,,3 C, P°°O4q°°O P 6,3v °°P P 4 p 4 6 4 D 4 0 4 D D 4 D 9 D D° D 4 D° 4 p D° D 4 D° 4 p po D 4 D° 4 p po D 4 v6 4D P° 4 0046 q° 4 P44p P° 4 P° q Do p4o3 D4°o p48o D4°o p4, d 1> p4°o C, pQ 4 DP b4 Dp 1>4 Dq p4 D°p4 Dq DI ^jaaj n7 D4 D°p4 Dq bq D°Q4 4Ppo6 DP4 P4oooD 4 q'3 n a D oD 4 °Q D °D 4 P t, Q 4 P17 o41> PP4° se -0 4gDq oP4° 44,4 004°°4 1> 4 pq°°q 00°9 O°°9 q°LJJ 00°q p°°° PP p°°P p°°P7 D4 D D4 D 4 D D4 D D4 D D9 D D4 D D4 D D °D 4 P4 D poD 4 P4 D oD 4 p4 D oD 4 P 0 4 Po4D 7° 4 Poop Po 4 go40 °0 4 P 4° 4D4° 4 0, 4D4° 4D4o 4D4o 4 °4 Dq 64 D°p4 DPD4 DP p4 Dqo .D4 ° D 4 p4 p° D d P4 0 - N P P4 PdoD40 c°-0oo o Ove(,1L1 Dp°4P 4 ?a v RtY ra?
