Technical Memorandum
Date:
March26, 2011
Project: WO#2 – Reedy Creek
Subject:
Reach 5 Assessment (Southwest Reach)
To: William Harris, E.I.
Purpose: For Review
Assessment
Kimley-Horn and Associates, Inc. (KHA) staff Will Wilhelm and Jason Diaz performed a visual assessment of the
subject site on May 13, 2011. The lower 500 feet of stream (reach 5) showed obvious visual signs of impairment
through bed/bank erosion and active headcuts. The stream does not have access to an active floodprone area/bench
because of this down-cutting/incision. This incision is likely caused from historical straightening and historic land
uses. However, upstream of this unstable 500 feet the stream visually appeared to be in a stable condition with
adequate access to a floodprone area. The stream makes this transition from a highly unstable to stable at a large
headcut that has been stopped by a large bedrock outcrop. Upstream of the bedrock the stream and its tributaries
appear to be in equilibrium with little or no signs of instability. These reaches are ideal for reference reaches for the
restoration efforts in the other Reedy Creek reaches.
Mitigation Potential
A majority of the stream (reach 5) and its tributaries (reach 5-A and 5-B) are contained on public property and
approximately 1,200 feet of reach 5-B is located on a private parcel (See Figure 1). Table 1 below lists the parcels
and owner names. All of reach 5 and its jurisdictional tributaries would qualify for mitigation credit ratio assuming
conservation easements were obtained and the Interagency Review Team (IRT) agreed to allow preservation on
within the existing nature preserve. The City may argue that the mitigation plan for this area is a complete watershed
approach and incorporates restoration and preservation to protect the watershed and its assets in perpetuity through
measures such as a conservation easement. Table 2 and Figure 1 below summarize of the estimated mitigation
potential of the reach when combined with the other components (Reach 1-4) of the Reedy Creek project:
