SECTION 401 WATER QUALITY CERTIFICATION
Certification issued to: Effective: December 18,2006
City of Ames, 515 Clark Avenue,Ames,IA 50010
Project certified: US Army Corps of Engineers,Joint Public Notice No. CEMVR-OD-P-2006-1050
State 401 Water Quality Certification,Application Log No.: 06-K-169-I 1-04-S
Proposal to widen and pave approximately 5400' of Southeast 16t" Street between South Duff Avenue and
South Dayton Avenue and replace an existing bridge crossing the Skunk River in SI 1-14,T83N,R24W,Story
County. A pedestrian trail will be constructed along the roadway alignment. The bridge and roadway will
impact approximately 1.01 acres of primarily forested wetland. To mitigate for wetland impacts,
approximately 1.52 acres of wetland and 0.5 acre of upland buffer will be created onsite.
Water quality use designation:
The South Skunk River is designated as a Class Al Primary contact recreational use. These are waters in
which recreational or other uses may result in prolonged and direct contact with the water, involving
considerable risk of ingesting water in quantities sufficient to pose a health hazard. Such activities would
include,but not be limited to, swimming,diving,water skiing,and water contact recreational canoeing. The
Skunk River is also designated as a warm water Type 2 Class B(WW-2). These are waters in which flow or
other physical characteristics are capable of supporting a residential aquatic community that includes a
variety of native nongame fish and invertebrate species. The flow and other physical characteristics limit the
maintenance of warm water game fish populations. The waters generally consist of small perennially flowing
streams. The impacted wetlands are designated as General Use Water and are protected at all places at all
times for livestock and wildlife water, aquatic life, non-contact recreation, crop irrigation, and industrial,
domestic,agricultural,and other incidental water withdrawal uses.
The Iowa Department of Natural Resources (IDNR) has issued this State 401 Water Quality Certification
pursuant to Section 401 of the Clean Water Act. The Army Corps of Engineers (Corps) requires state
Certification before a Section 404 permit can be issued. Section 401 Certification represents the IDNR's
concurrence that the project certified is consistent with the Water Quality Standards of the state of Iowa as set
forth in Chapter 61,Iowa Administrative Code. Subject to the attached conditions,incorporated by reference
herein, the IDNR has determined that there is reasonable assurance the proposed activities will be conducted
in a manner that will not violate water quality standards of the state of Iowa.

p g p
be required by the IDNR, federal, state, or local governmental agencies for the project activities
described.
2. You are encouraged to conduct your construction activities during a period of low flow.
3. Clearing of vegetation, including trees located in or immediately adjacent to waters of the state, shall
be limited to that which is absolutely necessary for construction of the project. All vegetative clearing
material shall be removed to an upland,non-wetland disposal site.
4. All construction debris shall be disposed of on land in such a manner that it cannot enter a waterway
or wetland. Construction equipment, activities, and materials shall be kept out of the water to the
maximum extent possible. Equipment for handling and conveying materials during construction
shall be operated to prevent dumping or spilling the material into waterbodies, streams or wetlands
except as approved herein. Care shall be taken to prevent any petroleum products, chemicals, or
other deleterious materials from entering waterbodies,streams or wetlands.
5. Erosion control features (i.e. silt fences silt ditches silt dikes silt basins etc.) must be installed to
provide continuous erosion control throughout the construction and post construction period as well
as the revegetation of all disturbed areas upon project completion. Where siltation control features
have been reduced in capacity by 50% or more, the features shall be restored to their original
condition with a minimum of delay.
6. All disturbed areas not covered with riprap shall be seeded with native grasses, excluding Reed
Canarygrass Whalaris arundinacea) or any aggressive or invasive species, during an optimal seeding
period. If excavation and construction are completed outside an optimal seeding period, temporary
erosion control protection shall be implemented immediately upon completion of excavation and
construction and shall be maintained until such time as seeding can be completed during an optimal
period. The applicant shall monitor revegetated areas continuously to assure success of revegetation.
If rye is initially planted to stabilize the soil then native warm season grasses shall be planted during
the following growing season.
7. If temporary crossings are needed for the project,then the temporary structures and fills shall involve
the least damaging and minimum amount of disturbance/ impacts to waters of the state and
appropriate measures must be taken to maintain near normal downstream flows,allow the passage of
fish, and minimize flooding. Fills shall be constructed of clean aggregate of suitable size to prevent
washing out of the structure by high flows. All temporary fills shall be completely removed to an
upland, nonwetland site and the area restored to pre-project conditions within 30 days of the end of
their use.
8. Flowable mortar shall be kept out of the stream.
9. The removal of the old bridge structure will include the piers and the removal will be in conformance
with all applicable state and local requirements. The old bridge and its piers will be removed to at
least one foot below the natural river bed.
10. Any debris from the bridge removal that falls into the water will remain there only temporarily and
will be removed accordingly. The debris will be properly disposed of in an upland,non-wetland
location.
11. Acceptable revetment material includes clean: riprap, field stone, quarry rock, and broken Portland
Cement Concrete (PCC). When using broken FCC,all exposed reinforcing steel rod or mesh must be
completely removed from it; if removal is not possible, the reinforcement material shall be cut flush
with the surface of the concrete prior to placement. It shall be the applicant's responsibility to
maintain the riprap such that any reinforcement material that becomes exposed in the future is
Pie s
removed. Any concrete pieces larger than three feet in average diameter must be broken into smaller
pieces prior to placement. The revetment shall consist of a uniform mixture of sizes of material laid to
form a compact surface capable of resisting erosion. The use of asphalt or other solid waste is
prohibited. The horizontal thickness of the revetment shall not exceed four feet. The finished slope
on the revetment shall be no steeper than two feet horizontal to one foot vertical (2H:1 V).
MITIGATION CONDITIONS
1. Mitigation shall be completed within one year from the date that the first fill is placed in any wetland.
An as-built plan shall be submitted to the IDNR and to the Corps upon completion. The 1.52-acre
replacement wetland shall be monitored annually and managed to confirm whether it has
successfully replaced the function and values of the impacted wetlands after a five-year period. If,at
the end of the fifth year, the expected water level is not achieved, more than 50 percent of the
emergent vegetation are non-native species,tree survival,by species,is less than the 80 percent, or if
evidence exists that the replacement wetland is becoming less effective, then additional monitoring
and/or corrective actions shall be taken to achieve the compensation ratio as originally approved.
Annual monitoring reports shall be submitted to the IDNR and to the Corps'office by December 31 for
at least five years following planting.
2. By the end of September of each year the tree plantings will be reviewed. Seedlings shall be replanted
as necessary to ensure an 80% survival rate by species.
3. Future development or land-use conversion of the wetland mitigation area, or any part thereof, for
any purpose that may interfere with or be detrimental to wetland functions, is prohibited without
prior written approval from the IDNR and the Corps. Prior to commencement of project construction
the applicant shall, with the knowledge and approval of the property owner of record, file a copy of
this certification in its entirety with the County Recorder for entry into the property records,thereby
notifying all parties of this restriction. Further, prior to commencement of construction, said
applicant shall provide the IDNR and the Corps with a "Filed" stamped copy of this certification. If
the certification cannot be filed in the manner indicated, the applicant shall provide the IDNR with
documentation of agreements, contracts, etc., demonstrating to the IDNR's satisfaction that the
wetland mitigation site will be protected from future activities that may interfere with or be
detrimental to wetland functions and values to a level of assurance equivalent to that provided by the
aforementioned filing process.
4. The mitigation concept proposed in the joint application form prepared by Terracon (October 18,
2006) shall be followed when constructing the mitigation sites. The City will create/restore 1.52
acres of wetland and 0.5 acre of upland buffer to compensate for the impacts to 1.01 acres of
primarily forested wetland. The City of Ames shall assume all liability for accomplishing any needed
corrective work. Corrective work will be required if 1.52 acres of wetland not develop as wetland
(according to the '87 Manual) or if the Corps determines that the mitigation site is not developing
satisfactorily. Remedial work may include grading and/or planting the mitigation site, or may
require a new mitigation site.
5. The annual site surveys of the mitigation site shall assess the vegetation, hydrology, and soils. The
results of each survey will be documented in an annual monitoring report. Annual monitoring
reports shall be submitted to the IDNR and to the Corps by December 31 for at least five years
following planting. The reports must include photos, a vegetative cover map indicating dominant
species in each area, an assessment of wetland hydrology according to the 1987 Corps of Engineers
Wetland Delineation Manual ('87 Manual),a map with drawn boundaries indicating exactly what
areas are wetland according to the '87 Manual,and any corrective actions taken or needed. All maps
must be to scale and have the scale plainly labeled.

1.0 INTRODUCTION
�d
Terracon was retained by the City of Ames and Engineering Alliance, Inc. to develop a
mitigation plan for the SE 161h Street paving and bridge replacement project in Ames, Iowa.
The subject site is located in portions of Sections 11, 12, 13 and 14, Township 83 North, Range
24 West, Story County, Iowa as depicted on Figure 1 in Appendix A.
Terracon performed a wetland delineation for the proposed project and identified thirteen
l wetland areas. The locations of the wetlands can be seen on Figure 2 in Appendix A. We
J� identified 1.324 acres of wetlands, of which 1.01 acres will be impacted by the project. Please
note that following submittal of the delineation report, wetland areas WL-4 and WL-6 were
extended north based on updated project boundary information.
One Water of the United States (WUS), the Skunk River, was identified within the project area.
y The locations of the WUS can be seen on Figure 1 in Appendix A. The project will include
replacement of the bridge across the Skunk River, as shown on Figure 3 (Sheet 3) in Appendix
A.
2.0 UNAVOIDABLE IMPACT DISCUSSION
The City of Ames is in the process of implementing long-range plans for street improvements.
The plans include paving approximately 5,400 feet of SE 16th Street between South Duff
Avenue and South Dayton Avenue. The project area can be seen on Figure 2 in Appendix A.
The street project is vital for the future growth of the City and the paving is necessary for safety
purposes and to handle increased traffic in the area. The City will be paving the existing gravel
road and providing two traffic lanes. A pedestrian trail and canoe access/parking area will also
be installed along the alignment. The centerline of the proposed alignment will coincide with
the existing road alignment to minimize impacts to surrounding property owners. The
pedestrian trial will be located on the north side of the road.
A secondary purpose of the roadway and bridge improvements is to lessen the effects of
flooding on SE 16th Street. The Skunk River has flooded the existing road/bridge approximately
five times since 1993. The current roadway and bridge were designed to withstand a 10 to 20

year storm event. The proposed� Y p posed roadway will remain above water following a 50 year storm
event and the new bridge will withstand a 100-year storm event.
The project will include the replacement of the existing 20-foot wide pony truss bridge with a 36-
foot wide bridge. The road profile on the eastern half of the project will be raised approximately
two to five feet above the current roadway and the elevation of the bridge will be
proposed
- approximately five feet above the elevation of the existing bridge. Wing walls will be installed at
the bridge to divert flood water beneath the bridge to minimize the effects of flooding. The
channel of the Skunk River near the bridge will be widened to reduce the effects of flooding to
SE 16th Street and to improve hydraulics of the bridge.
The proposed SE 16 thStreet paving and bridge replacement project is necessary to support
future growth of the City as well as to provide additional protection and safety against future
flood events.
3.0 IMPACTED JURISDICTIONAL WETLANDS
Terracon identified thirteen wetlands within the project area. Of the 1.324 acres identified at the
site, 0.314 acres would be considered isolated by the U.S. Army Corps of Engineers (USACE).
The following wetlands are considered isolated roadside ditch wetlands W L-1, W L-2, W L-3,
portions of W L-4, W L-5, W L-7, W L-8, portions of W L-9, W L-10, W L-11, W L-12, and W L-13.
i
Wetland W L-6 and the portions of W L-4 and W L-9 adjacent to the Skunk River would be
considered jurisdictional. Please note that following submittal of the delineation report, wetland
areas WL-4 and WL-6 were extended north based on updated project boundary information.
_ The proposed trail will impact 1.01 acres of jurisdictional wetland. The following sections
address the jurisdictional wetland on the project site. Details concerning the amount of
delineated and impacted wetlands can be seen on Table 1 in Appendix B.
3.1 Wetland Area 4
Wetland Area 4 (WL-4) is located north of SE 16th Street in the central portion of the site. The
wetland delineation report identified 0.387 acres at WL-4; however following submittal of the
delineation report, the boundary of WL-4 was extended north based on updated project
information. The western portion of WL-4 (0.06 acres) is located in a within a roadside ditch
and would be considered isolated. The jurisdictional wetland along the Skunk River covers
approximately 0.52 acres; however the wetland appears to extend throughout the forested
L bottomland along the river and only the area in the vicinity of the project was delineated. The
isolated and jurisdictional wetland areas are depicted on Figure 2 in Appendix A. Approximately
0.52 acres of jurisdictional wetlands will be impacted by the project.

The dominant wetland species present included sedge species, reed canary grass, green ash,
silver maple, bedstraw and wild violet. The jurisdictional portion of the wetland would be
considered forested. It appears that the wetland is receiving hydrology from surface water run-
off and the Skunk River. The soil characteristics appear to be similar to Coland clay loam,
which is listed on the Story County and national hydric soil lists.
3.2 Wetland Area 6
- Wetland Area 6 (WL-6) is located north of SE 16th Street in the central portion of the site. The
.� wetland delineation report identified 0.358 acres at WL-6; however, the boundary of WL-6 was
extended north based on updated project information. The jurisdictional wetland along the
Skunk River in the project area covers approximately 0.44 acres; however the wetland appears
to extend throughout the forested bottomland along the river and only the area in the vicinity of
the project was delineated. The wetland area is depicted on Figure 2 in Appendix A.
r Approximately 0.44 acres of jurisdictional wetlands will be impacted by the project.
The dominant wetland species present included sedge species, reed canary grass, stinging
nettles, green ash, wood nettle, wild violet, bedstraw and silky dogwood. This area would be
considered a forested wetland. It appears that the wetland is receiving hydrology from surface
water run-off. The soil characteristics appear to be similar to Coland clay loam, which is listed
on the Story County and national hydric soil lists.
3.3 Wetland Area 9
IM
Wetland Area 9 (WL-9) is located south of SE 16th Street in the central portion of the site. The
wetland delineation report identified 0.128 acres at WL-9. The eastern portion of WL-9 (0.078
acres) is located in a within a roadside ditch and would be considered isolated. The
jurisdictional wetland along the Skunk River covers approximately 0.05 acres. The isolated and
jurisdictional wetland areas are depicted on Figure 2 in Appendix A. Approximately 0.05 acres
l of jurisdictional wetlands will be impacted by the project.
The dominant wetland species present included sedge species,
g p s, reed canary grass, green ash,
stinging nettles, cattail, and silky dogwood. This area would be considered a wet meadow
wetland with minor tree growth. It g appears that the wetland is receiving hydrology from surface
water run-off and the Skunk River. The soil characteristics appear to be similar to Coland clay
loam, which is listed on the Story County and national hydric soil lists.

4.0 IMPACTED WATERS OF THE UNITED STATES
* The Skunk River was identified on the USGS Topographic Map (Figure 1 in Appendix A) and
would be considered a Water of the United States. A proposed bridge will impact the Skunk
River at one location. Construction plans for the proposed bridge can be seen as Figure 3
(Sheet 3) in Appendix A.
The proposed bridge will be 36 feet wide, will span 304 feet between abutments, and will have
two supporting piers within the Skunk River. The existing 2 Pp g P g 0 foot wide, 273 foot long pony truss
�i bridge and two associated piers will be removed as part of the project. The banks of the Skunk
r
River on either side of the bridge will be reshaped to improve the hydraulics of the river at the
bridge. Rip rap will be installed along portion of the re-graded channel. The new grading will
create a 170-foot wide channel bottom. Wing walls will be constructed on either side of the
bridge abutments to provide additional flood protection for the roadway and bridge. Details
I regarding the wing walls can be seen on Figure 3 (Sheet 3) in Appendix A. Wetlands WL-4,
ol
WL-6 and WL-9 were identified adjacent to the Skunk River near the proposed bridge.
5.0 FUNCTIONS AND VALUES OF THE JURISDICTIONAL WETLAND
The functions and values for the jurisdictional wetland are based on the "The Highway
Methodology Workbook Supplement: Wetland Functions and Values" 1995 The methodology
evaluates wetland functions and values from a descriptive approach. A jurisdictional wetland
I:
may have the following functions and values:
groundwater recharge/discharge,
flood flow alteration,
a� • nutrient removal/retention/transformation,
• production export,
• sediment/shoreline stabilization,
• wildlife habitat,
• recreation,
• educational/scientific value,
• uniqueness/heritage,
• visual quality/aesthetics, and/or
• endangered species habitat.
The principal functions of the jurisdictional wetlands for the proposed project are groundwater
recharge/discharge, flood flow alteration, nutrient removal/retention/transformation, sediment

stabilization, and wildlife habitat. The wetlands consist of wetland herbaceous and forested
species primarily along the river.
6.0 PROPOSE® MITIGATION SITE
Engineering Alliance, Inc. and the City of Ames have chosen to y create an on-site mitigation
area adjacent to the Skunk River north of SE 16"' Street to offset the wetland impacts. The
mitigation site is located directly west of W L-4, as shown,on Figure 2 in Appendix A. The
mitigation site is located within a 2.2-acre property that will be purchased by the City.
Terracon designed a 1.52 acre wetland mitigation area that will consist of forested wet meadow
and emergent wetlands between the elevations of 52 and 55 feet. Approximately 0.5 acres of
buffer will be planted around the mitigation site. Surface water runoff from surrounding upland
areas will support the mitigation site.
A mitigation ratio of approximately 1.5 to 1 was selected based on the quality and diversity of
the delineated wetlands and the use of an adjacent mitigation site. The planting plan for the
mitigation area will result in higher quality wetlands with more diverse tree and plant species.
The mitigation plan will include tree and shrub plantings for impacts to forested wetlands.
Additional details regarding tree plantings can be found in Section 10.2 of this report.
The "Soil Survey of Story County Iowa" identified Spillville loam and Coland clay loam soils in
the vicinity of the wetland mitigation area. Both soil types of were identified on the Story County
hydric soil list and Coland soils are included on the national hydric soil list. These soils will
- provide appropriate conditions for supporting the mitigated wetlands.
7.0 HABITAT/BUFFER AREA
In addition to the 1.52 acres of wetland mitigation, approximately 0.5 acres of buffer will be
planted around the mitigation site. The buffer will be planted with a wildflower and grass seed
mix, as described in Section 10.3 of this report.
�. The buffer area will reduce water quality p g impacts to the mitigation area and will enhance the
water quality within the site. The buffer will retain soil eroded from the upland ground and will
minimize siltation of the mitigated wetlands.
8.0 GOALS FOR THE MITIGATION SITE
The delineated wetlands are located in a forested bottomland adjacent to the Skunk River. The
City will be creating a wetland mitigation area directly upgradient from the impacted wetlands.

The mitigation area was designed to have similar functions as the existing wetlands and they
will provide the opportunity to increase the variety and quality of the wetland vegetation. The
mitigated wetland and surrounding buffer area will have functions including the following:
• Groundwater Recharge/Discharge: This function refers to the interaction between the
wetland and aquifer. The wetland mitigation area will provide enhanced functions for
groundwater recharge/discharge because it has been designed to contain overland flow of
surface water. The.water retained in the wetlands will slowly infiltrate through the base of
the wetland and be discharged into the aquifer and to the adjacent Skunk River.
• Flood Flow Alteration: This function considers the effectiveness of the wetland in reducing
flood damage by water retention for prolonged periods following precipitation events and the
gradual release of floodwaters. The wetland will provide storage capacity for surface water
during periods of heavy precipitation and flood events, releasing the water slowly through
infiltration.
• Nutrient Removal/Retention/Transformation: This function considers the effectiveness of the
wetland as a trap for nutrients in runoff water from surrounding uplands or contiguous
wetlands, and the ability of the wetland to process these nutrients into other forms. One
aspect of this function is to prevent ill effects of nutrients from entering aquifers or surface
waters. The mitigation area and adjacent buffer will help purify water by processing
nutrients, suspended materials, and other pollutants. Surface water will enter the wetland
and the flow rates will be reduced, allowing suspended materials time to settle. Wet
meadow and emergent wetland vegetation and tree growth will assist in nutrient removal
and transformation.
• Wildlife Habitat: This function considers the effectiveness of the wetland to provide habitat
for various types and populations of animals typically associated with wetlands and the
wetland edge. Wetlands provide breeding, nesting, feeding, and cover habitats for
invertebrates, insects, amphibians, reptiles, birds, and mammals. Migratory birds and
waterfowl use the ecosystems as food, shelter, breeding, and wintering grounds. Wetlands
can also potentially provide critical habitat for Federal and State-listed threatened and
endangered species. The wetland mitigation area will be adjacent to the existing forested
bottomland along the Skunk River. The wetland will provide enhanced functions of wildlife
habitat along the existing river corridor.

9.0 IMPLEMENTATION
LE E 'TATI®N PLAN
The objectives of the mitigation plan include creating a wetland that will have increased wetland
species diversity. An outline of the specification for the creation of the mitigation site includes
grading, water control structures, hydrogeoiogic study, and erosion control
9.1 Grading
The construction of the wetlands will consist of grading the area to the approximate elevations
shown on Figure 4 Appendix A. The wetland mitigation area will be present between the
elevations of 52 and 55 feet. The wet meadow zone will exist from approximately 54 to 55 feet
a and the emergent zone will exist below approximately 54 feet.
The mitigation area will be graded so that hydric soils are present to a depth of at least one-foot
in the mitigation area. Wetland topsoil shall be handled in a manner to avoid compaction of
undisturbed soils.
9.2 Water Control Structure
I One 24-inch culvert will be used to regulate the water level within the mitigation area. The
elevation of the culvert inlet will be set at 54 feet. The approximate location of the proposed
culvert can be seen on Figure 4 in Appendix A.
I
9.3 Hydrologic Study
A hydrologic study has been performed to evaluate if the mitigation site will have enough
q,J
surface water to provide saturated soils in the upper 12 inches of the wetland mitigation area. A
water balance analysis was conducted on the site area to evaluate the amount of percolation to
the water table after wetland development. The water balance is based on the relationships
between precipitation, evapotranspiration, surface runoff, and soil moisture. Averages of normal
_ mean monthly precipitation and temperature were used. Based on the Story County soil survey
data, the soils within the wetland mitigation areas have high available high water capacity
(available moisture capacity). In order to present a more conservative estimate of soil moisture
storage, the available moisture capacity was assumed to be in the low to moderate range.
3 The water balance analysis indicates that approximately 2 to 6 inches of soil moisture storage will
be available in the wetland mitigation site throughout the year. The wetland should receive
sufficient stormwater/groundwater runoff throughout an average year to support wetland
1 u conditions. It is likely that the annual precipitation, along with the estimated soil moisture storage,

will be sufficient to maintain hydrology within the proposed wetland area given the structural
controls of the mitigation site.
9.4 Erosion Control Measures
Erosion control measures will be utilized throughout the site until vegetation becomes
established. The contractor will be responsible for installation and maintenance of the erosion
control measures throughout the duration of construction.
10.0 PLANTING SCHEDULE
10.1 Wetland Seeding
Seeding of the mitigation site will occur after earth moving and shaping of the site has been
completed. If longer periods of time occur between shaping and the recommended planting
time, final disking and harrowing preparation of the hydric soils will not take place until just prior
to planting.
Seeding will be conducted by hand or by other methods of broadcasting before the mitigation
area is submerged up to the normal pool. Seed should be applied at a rate of at least 12
pounds per acre. In order to ensure an even broadcast of seed, the seed may be mixed
thoroughly using ten parts of moist sand to one part seed. The seed mixture could be
purchased from Ion Exchange Native Seed and Plant Nursery in Harpers Ferry, Iowa or from a
comparable vendor. The seed should be of Iowa origin, adjoining states, or as specified.
Terracon recommends that the seed mixtures be a Wet Meadow Site Mix for the wet meadow
wetlands in the mitigation area and an Emergent Site Mix for the emergent wetlands. The
recommended seed mixtures are listed in Appendix C. The wet meadow and emergent zones
can be seen on Figure 5 in Appendix A. Approximately 0.6 acres of emergent seed and 1.0
acres of wet meadow seed should be planted in the mitigation area.
The following seeding methods should be utilized in the mitigation area:
• Frost Seeding (February through March — Broadcast the seed onto the seedbed
( Y 9 ) ,
which was prepared in the fall. Allow the freeze/thaw process to work the seeds into
the ground.
® Spring Seeding (April through June) — Broadcast the seed into a firm, well-prepared
seedbed. Lightly rake or till the seed mix into the soil. Roll or compact the seedbed
after the seeds have been raked in. Keep the area moist, but not wet over the next
few weeks.

variety, origin, and analysis of the seed will be submitted to the USACE.
10.2 Tree Planting
The proposed project will impact forested wetlands, as detailed on Table 1 in Appendix B.
Mitigation for forested wetland impacts will include tree plantings at a rate of 100 trees per acre
for 5 gallon pot size trees or 200 trees/acre for 2 gallon pot size trees (see Table 1 in Appendix
B). Shrubs will be planted at a rate of 50 shrubs per acre. Based on the impacted acres as
shown on Table 1 in Appendix A, 51 shrubs and 97 5-gallon of size trees or 193 2-gallon
p ( g n pot
size trees) should be planted within the mitigation area. The following species shall be planted
within the wetland.

within the lower wet meadow elevations. Species with a wetland indicator of FACW+ and
�- FACW shall be planted within the wet meadow or lower elevations of the buffer area. Species
I ! with a wetland indicator of FAC and FAC- shall be planted within the upper elevations of the wet
meadow or within the buffer area. Species with a wetland indicator of FACU shall be planted in
r' the buffer area. Any trees/shrub species substituted must be pre-approved by the USACE and
�- be seed, nut, or fruit producing with a wetland indicator of OBL, FACW, or FAC.
r We recommend that tree guards be placed around the tree trunks to protect them from wildlife
grazing. Tree species will be planted at a minimum spacing of 25 feet. The vegetation will be
kept shaded and moist during transportation and prior to planting. Planting shall not occur until
after earth moving and shaping of the wetland mitigation site is completed. We recommend
that the trees/shrubs be mulched, staked/guyed, pruned, and watered in accordance with the
Urban Standard Specifications.
10.3 Buffer Area Planting
� Approximately 0.5 acres of buffer wil
l be planted in the disturbed area surrounding the wetland
mitigation area, as shown on Figure 5 in Appendix A. The buffer will be planted with a variety of
non-wetland vegetation and meadow wildflowers. A recommended seed mix for the buffer
planting can be found in Appendix C.
Seed should be applied at a rate of at least 12 pounds per acre. In order to ensure an even
broadcast of seed, the seed may be mixed thoroughly using ten parts of moist sand to one part
seed. The seeding methods described in previous sections of this report should be utilized for
Sri the buffer area.

the variety, origin, and analysis of the seed will be submitted to the USACE. Documentation of
the variety and quantity of trees will also be submitted.
12.0 MANAGEMENT AND MAINTENANCE OF MITIGATION SITE
,y
The mitigation site will be visited once a year until the mitigation site is established. The site
3 visit will consist of observing wetland vegetation, recording growth progress, and noting whether
I wetland vegetation is competing with invasive weeds. Information collected from the field will
be reviewed to recommend best management practices for the mitigation site. The USACE will
receive a progress report annually until the mitigation site is established.
Based on our experience in wetland mitigation, we believe that the standard five-year annual
monitoring period is generally sufficient to determine if wetland features and goals are being
met at each phase of the project. During each of the annual monitoring reports damage and
mortality of the vegetation and trees will be assessed and the need for additional seeding or
i plantings will be evaluated and discussed. Following the monitoring period, the need for
additional monitoring will be assessed if the wetland goals are not being met.

(- 13.0 GENERAL COMMENTS
i
The analysis and opinions expressed in this report are based upon the data obtained from field
studies and surveys at the indicated locations and from other information discussed in this
report. This report does not reflect any variations that may occur across the site.
i
L The client should understand that a mitigation plan is a conceptual design to outline the details
of wetland mitigation activities proposed for the site for regulatory approval. It should not be
relied upon for construction. We recommend that detailed engineering plans and specifications
be developed upon approval of this plan and prior to construction.
This report is prepared for the exclusive use of our client for specific application to the project
as discussed and has been prepared in accordance with generally accepted local assessment
practices within the scope of the client's directives. No warranties, either expressed or implied,
are intended or made.
