Re: Management and Monitoring Report
Eagle Ridge Golf Community; USACE Action ID #199910576,
NC DENR Division of Water Quality Project # 960722
SEI Project #9905022
Dear Mr. Alsmeyer:
Pursuant to US Army Corps of Engineers Action ID #199910576, please find the enclosed
management and monitoring report, dated September 3, 2002.
Included in the report, please find an assessment of general ecological condition, hydrologic
observations and planted vegetation condition. As you can see, these criteria were qualified in
the field for general diagnostic purposes in order to produce the accompanying preliminary
mitigation management schedule and conceptual stream restoration plan. A more detailed
quantitative assessment will follow as our mitigation management schedule progresses, i.e. well
readings for estimating the area of saturation within the wetland creation area; channel width to
depth ratios in the stream relocation area; and areal coverage of native species throughout the
mitigation areas.
If you have any questions regarding our preliminary mitigation management schedule or
conceptual stream restoration plan, please call.
Sincerely,
Spangler EqLr r nmental, Inc.
Mark Vosberg

Management and Monitoring Report

1. General Ecological Condition: Ecosystems developing towards dynamic equilibrium such as the created wetland and riparian
areas onsite are susceptible to invasion by exotic species and/or erosion due to channel scour, i.e. in the absence of management, the
created wetland/buffer area is developing into a low quality scrub-shrub/forested wetland (Photos 1-4); and the stream relocation area
is developing depositional features in its upper and lower reaches (Photos 5-7) while its middle reach is developing erosive features
(Photos 8-10).
2. Hydrologic Observations: Permanent to semi-permanent inundation in the absence of periodic draw down appears to be creating
an early successional scrub-shrub/forested wetland dominated by Tulip Poplar (Liriodendron tulipifera), Black Willow (Salix nigra),
Sweetgum (Liquidambar styraciua), Blackberry (Rubus argutus) and Small Evening Primrose (Oenothera perennis); the erosion due
to down cutting and bank scour appears to be a function of increasing velocity from the streams' relatively steep (g = 0.64%) upper
reach and a moderate gradient (0.42%) within the streams' middle reach.

4. Specific Management Recommendations: In response to USACE and NC DENR Division of Water Quality mitigation
compliance requirements, Spangler Environmental staff recommends: a) an applied ecological approach to the eradication of invasive
plants from the wetland creation area in order to restore the intended fresh water marsh community type as shown by the attached
preliminary mitigation management schedule; and b) the implementation of similar applied geomorphological approach for the
restoration of the stream relocation area as illustrated by Figure 1.
This management and monitoring - short form was produced by Spangler Environmental, Inc. to: a) provide our clients and the Army Corp of Engineers with an
accurate and timely response to Section 404 permit requirements and/or special conditions; and b) to minimize the time and paperwork involved with periodic
reporting requirements.
