DATE: 04-14-20
COUNCIL ACTION FORM
SUBJECT: PRELIMINARY PLAT FOR CORNER OF SE 16T" STREET AND
S DAYTON AVENUE AT 1499 S DAYTON AVENUE.
BACKGROUND:
Wheelock Corner Subdivision is a proposed 16.47-acre development on the northwest
corner of the intersection at SE 16th Street and S Dayton Avenue. See a location map in
Attachment A. The property owner, DW Holdings, LLC., requests approval of a
preliminary plat creating 6 lots. There are six developable parcels and proposed public —
right-way, Isaac Newton Drive, that will provide access throughout the development. (Lot
Layout-Attachment B)
All six lots will have access off of the newly extended Isaac Newton Drive. Direct access
to SE 16th Street and S Dayton Avenue will be prohibited. Shared access to the Theisen's
will also remain.
The entire site is located within the floodplain and are subject to requirements of Chapter
9 of the Ames Municipal Code. At the western end of the site, a portion of Lots 2 and 3
(3.66 Acres) lie within the Floodway. No development is proposed in this area; however,
storm water management features are located in this area. Development within the Fringe
area is required to have a building's finished floor three feet above the base flood
elevation. Grading and fill for the individual lots will occur at the time of their development.
Any disturbance in the Floodway is required to meet a no-rise standard for the base flood
elevation.
The floodway area of Lots 2 and 3 are located in the Environmentally Sensitive Overlay
District, O-E. This site is the first project to request approval of grading or improvements
that lie within the O-E District. The standards of Ames Municipal Code, Section 29.1103,
intend to protect designated natural resource areas by using an environmental
assessment (Attachment F) and requiring mitigation of significant issues related to
identified environmental conditions. In this case, consideration of potential flooding,
wetlands, riparian habitat, and woodland impacts. Based upon the biological assessment
and review of Chapter 9 Flood Plain regulations, the proposed storm water detention
facilities do not cause and significant adverse impact on the identified resources. Note
that in the site exhibits of Attachment F, the study area includes lands to the west of the
proposed subdivision.
Water, sanitary, and storm sewer are all proposed within the subdivision. Five-foot
sidewalks are proposed on both sides of Isaac Newton Drive and along S Dayton Avenue.
A shared use path already exists along SE 16th Street. Future street improvements are
planned for S Dayton and SE 16th Street that are not related to the proposed subdivision.

Planning and Zoning Commission: At its meeting on March 18, 2020, the Ames
Planning and Zoning Commission voted 4-0 to recommend approval of the preliminary
plat to the City Council with a condition that the applicant clarify the preservation of the
oak woodlands that were identified in the inventory. The applicant was not in attendance
at the meeting.
After Commission's discussion of the Environmental Assessment Report, a
recommendation for approval was made with the condition that the applicant
clarify the preservation of the oak woodlands that were identified in the Environmental
Assessment Report. Staff has responded to this recommendation of the Planning and
Zoning Commission by adding a condition for creation of a conservation easement related
to tree preservation prior to approval of the final plat.
ALTERNATIVES:
1. The City Council can approve the Preliminary Plat for Wheelock Corner Subdivision,
subject to approval of Flood Plain Permit by the City of Ames and other affected
agencies and with the condition that the applicant provide a Conservation Easement
prior to final plat approval related to preservation of Oak woodlands that were
identified in the inventory.
2. The City Council can approve the Preliminary Plat for Wheelock Corner Subdivision,
subject to approval of Flood Plain Permit by the City of Ames and other affected
agencies.
3. The City Council can deny the Preliminary Plat for Wheelock Corner Subdivision, by
finding that the Preliminary Plat does not meet the requirements of Section
23.302(3)(b) or Section 23.603 of the Ames Municipal Code and by setting forth its
reasons to disprove or modify the proposed preliminary plat as required by Section
23.302(4) of the Ames Municipal Code.
4. The City Council can defer action on this request to the next regular meeting and refer
it back to City staff and/or the applicant for additional information.
CITY MANAGER'S RECOMMENDED ACTION:
This preliminary plat proposal includes six developable commercial lots. The preliminary
plat identifies all the necessary infrastructure to serve the proposed commercial lots,
reserves the Floodway from any development, and dedicates a portion of right-of-way for
sidewalk extension to the City's trail system. The Environmental Assessment Report
shows no adverse impact to environmentally sensitive areas, e.g. wetlands and
established woodlands, in the floodway due to the design and location of the
improvements as well as no rise in the base flood elevation as the result of the
construction of the storm water detention basin. However, an additional step of providing
a Conservation Easement that prohibits the removal of healthy and mature trees provides
additional support towards preserving the identified oak woodland resources consistent
with the intent of the Overlay.
2
City staff has reviewed the proposed plat and find it conforms to the requirements of the
Ames Subdivision regulations in meeting infrastructure requirements with appropriately
designed lots for commercial use. Prior to final plat approval the applicant will seek
additional permits for flood plain improvements and each site development permit will also
require individual flood plain permits.
Therefore, it is the recommendation of the City Manager that the City Council support
Alternative #1 thereby approving the Preliminary Plat for Wheelock Corner Subdivision,
subject to approval of Flood Plain Permit by the City of Ames and other affected agencies
and with the condition that the applicant provide a Conservation Easement prior to final
plat approval related to preservation of Oak woodlands that were identified in the
inventory.

Addendum
General Site Info
The site is currently an unplatted parcel of about 16.4 acres. The site is zoned Highway
Oriented Commercial, HOC and has the Southeast Gateway Overlay District designation.
The site is relatively flat although, approximately 3.6 acres, is located within the
Environmental Sustainability Overlay. Attachment F includes the required Environmental
Assessment Report.
The site has commercial development on the north, east, and south sides and all are
zoned Highway Oriented Commercial (HOC). The Southeast Gateway Overlay
designations exists on the properties to the east and south. The adjacent land to the west
is located within the Floodplain and undeveloped at this time. See Attachment C.
Lots
The proposed preliminary plat will yield six developable lots. The lot sizes range from .75
acres to 4.70 acres. The approximate western half of Lots 2 and 3 will not be developable
since they are located within the Environmentally Sensitive Overlay District. Note that by
having this area as part of the individual lots rather than as a separate outlot, it allows for
calculation of development standards for floor area ratio to occur across the gross lot
area, therefore allowing for more development potential in relation to floor area ratio
limitations.
Notably, Theisen's has an existing driveway access through the site. This existing access
is incorporated into area of proposed Lot 1.
Along the southern boundary of the proposed plat, there is a 0.45 acre parcel owned by
Story County. This parcel will remain as is in ownership and size. This parcel was
purchased by Story County with federal funds under a flood mitigation buyout program
with the condition that no changes can be made to it or construction upon it. The applicant
will landscape this lot and includes drainage swale through this area with acceptance by
Story County. The lot will function as "front yard" area along SE 16th Street.
Streets
A new street, Isaac Newton Drive will run through the site, providing a connection between
SE 16th Street and S Dayton Avenue. It will be designed as a Commercial Collector street,
with a 66-foot right-of-way, with a paving width of 31 feet. Access to all lots will be off
Isaac Newton Drive. Direct access to SE 16th and S Dayton Avenue will be prohibited.
The City is in the process of planning for street improvements at the intersection of S
Dayton Avenue and SE 16th Street. These improvements are unrelated to the proposed
development but spacing and right-of-way needs have been coordinated with the
proposed plat layout.
Water
An 8-inch public water main will be extended along the Isaac Newton Drive right-of-way
from an existing off-site main on the south side of SE 16th Street. This public water main
4
will be providing service to future proposed hydrants and extensions of the main will serve
each commercial lot.
Sewer
An 8-inch public sanitary sewer line running through it currently. It will be extended along
the Isaac Newton Drive right-of-way from an existing main that is already extended from
S Dayton Avenue. Manholes will be installed and public sanitary sewer mains will provide
service all lots.
Sidewalks and Trails
A five-foot sidewalk is required and will be installed along the frontage of Isaac Newton
Drive on both sides of the right-of-way. A five-foot sidewalk will be installed along S
Dayton Avenue. An eight-foot shared use path already exists along SE 16th Street. A
sidewalk ramp already exists to allow pedestrians to cross S Dayton Avenue. There is not
a ramp proposed to provide a crossing to the south side of SE 16th Street due to a lack of
receiving sidewalk facility. Future improvements at that that intersection will address
appropriate and safe pedestrian crossing requirements.
A private drive already exists from the Theisen's site south to connect with S Dayton
Avenue. This private drive will remain and connect with the new street, Isaac Newton
Drive. A sidewalk crossing will be installed to the north of this intersection to allow
pedestrians to safely cross this frontage drive, since no changes are proposed to its
current design.
Storm Water Management
Public Works staff has reviewed the storm water management plan and finds that it meets
the capacity requirements of the City's ordinances. Further storm water information will
be needed prior to approval of a Minor Site Development Plan for each lot. For the
purposes of this preliminary plat, the proposed grading and detention plans can be
approved. A majority of the storm water runoff will be directed to a detention basin in the
western half of Lot 3. The northern half of Lots 1 and 2 will drain to the north to an existing
off-site basin.
Flood Plain
The western portion of Lots 2 and 3, approximately 3.6 acres is located within the
floodway. (See Attachment D). The rest of the site is located within the Floodway Fringe.
Development within the Floodway Fringe is allowed provided that buildings are elevated
or flood proofed to 3 feet above the Base Flood Elevation (BFE or the water surface level
of a flood having a 1 percent chance of occurring in any given year). Anything within the
Floodway is severely restricted and usually requires explicit approval by the City Council
through a Major Site Development Plan or a Preliminary Plat. In this case, no
development is proposed in the Floodway, other than the storm water facility. The
proposed grading is subject to the requirements of Flood Plain Zoning ordinance (Ames
Municipal Code Chapter 9) and the Environmental Overlay standard of Chapter 29.
5
Environmental Assessment Report
An Environmental Assessment Report is required as part of the Preliminary Plat approval
as the storm water detention basin for the development contained within the preliminary
plat is to be located in the O-E District, which qualifies as a development use in the
regulatory floodway (Chapter 9 of the Ames Municipal Code). This report (Attachment F)
is a supplement to the City's flood plain regulations and must show that the project will
protect designated natural resources areas through a natural resource inventory and
mitigate any negative effects on the floodway, or negative effects on the development as
a result of locating improvements in the designated area.
The Environmental Assessment report was completed by Impact 7G on behalf of the
developer. A portion of the study area is not part of this preliminary plat. It is on the
property to the west and is under the same ownership. Approximately, 1.4 acres of the
study area included is an Oak woodland area forested. This forested area is on the
western half of Lot 2 and does extend south onto Lot 3. As part of the review of the report
and discussion at the Planning and Zoning Commission meeting, it was stressed that this
wooded area should be preserved. The applicant did move the extent of the grading
outside the dripline of the trees. It is located within the floodway. Most work in a floodway
would need a Floodplain permit. However, there is no specific preservation method for
the forested area laid out. Staff assumes that the intent is to preserve the oak woodland
area but nothing in the Floodway regulations prevents or requires review prior to tree
removal. Requiring a Conservation Preservation Easement would be needed that
included language prohibiting the removal of trees. Staff feels that a Conservation
Preservation Easement would be the most direct way to protect the forested area.
The report indicates that the proposed storm water detention basin will not disturb any
wetlands or any impact on woodland areas. The applicant made adjustments to the
original design in response to the findings of the assessment. The grading plans also
show the elevation in the floodway will have no rise as a result of the project and any
excess soil or dirt will be removed from the floodway thereby not causing a shift in
elevation form one location to another. The construction of the detention basin can be
seen to not have a negative impact on water flow within the stream channel of the Skunk
River as any flooding would be accommodated within the storm water detention basin
capacity, which currently does not exist.

MEMO: Sec. 291103 "O-E" Written Inventory, Wheelock Corner Subdivision
To Whom it Concerns:
On behalf of Fox Engineering, Impact7G is providing the following assessment of the potential impacts to
Environmentally Sensitive areas,as defined in 29.1103 "O-E" Environmentally Sensitive Area Overlay of the
Ames City Zoning Code,associated with the Wheelock Development,located in Ames,Iowa.
Environmentally Sensitive Areas Not Present
The following Environmentally Sensitive Area types are not present,based on sources provided.
• Parks and Open Space Areas
• Aquifer Protection Areas
• Prairie'
o Impact 7G reviewed vegetation present throughout the project areas. No significant
assemblages of native grass species are present,per Norris, 1995.
• Streams2
o Impact 7G conducted onsite wetland and waters of the U.S. identification throughout the
project areas.No stream areas are present,per Norris, 1995.
• Special Resources3
Environmentally Sensitive Areas Present
Any Environmentally Sensitive Area types identified within the parcel or development vicinity,and thus with
the potential to be impacted for the above development,are listed below with status and comment.
Green-ways
• No Impact; resources avoided.
o An area designated as Green-way4 is located on the western edge of the parcel. No
development is currently proposed within several hundred feet of the Green-way.
Floodway&Flood Plains
• Impact to be permitted; State permit required.
o Current design calls for excavation and removal of soil from the existing grade and has been
positioned on the preliminary platting to avoid all wetland and woodland resources.
Activities within the floodway&floodplain will be coordinated through Iowa Department of
Natural Resources (DNR) Floodplains Department. Only excavation will occur within
Floodplain designated areas. No activity will commence in Floodplain or Floodway areas
prior to issuance of DNR Floodplain permits.

Designated Natural Resource Areas,as defined in A natural area inventory ofAmes,lowa.s
Wetland: No impact; resources avoided
o Delineated wetlands6 will not be impacted by project activities as all design plans entirely
avoid wetland areas.
o There are several wet or wetland-like areas (marked as developing wetland mosaic on
preliminary platting maps) that are likely the result of soil compaction due to the operation
of construction and farming equipment. These areas are likely to be found as non-
jurisdictional by the United States Army Corps of Engineers (USACE)-resulting in no impact
to wetlands pending a determination by the USACE.
• Woodland: No impact; resources avoided.
o Woodlands7 present within the project vicinity will not be impacted by development
activities.No trees in woodland areas will be removed.Grading and equipment operation will
occur outside the drip line of woodland canopies to the greatest extent possible to prevent
incidental damage to the trees'roots.
In summary,the planned Wheelock Corner Subdivision will have no impacts to wetlands,no removal of
woodland trees,and no negative impacts to the FEMA regulatory floodway of the South Skunk River,once
permitted.No other potentially designated Environmentally Sensitive Areas are present.

1.0 Executive Summary
1.1 Purpose & Need
Impact7G, (I7G) was contracted by FOX Engineering & Associates, Inc. to complete a wetland delineation
investigation and natural resources inventory for the proposed Wheelock Development, per City of Ames
environmental regulations.The intent of this investigation and report is to document existing site conditions,
at the time of investigation, as may be of consequence to any potential city, state, or federal regulatory
compliance needs.
1.2 Location
Street Address: 1499 South Dayton Ave
Ames, Iowa 50010
Township: 83N
Range: 24W
Section: 12
Quarter: SW&SE
See Figure C for Location Map.
1.3 Summary Findings
Impact7G delineated 0.29 acres of non-forested wetland and identified farmed areas of developing wetland
mosaic within the project boundary.
Other environmentally sensitive natural resources present within the investigation area include several large
native oak trees that provide elevated habitat and ecological value.
2.0 Methodology
For the purposes of the natural resource inventory,a field evaluation was conducted whereby all areas within
the project boundary were walked and photographed to identify areas of sensitive resources, elevated
diversity,remnant,or other habitat indicators.
2.1 Delineation of Wetlands
Field analysis was completed using the routine onsite determination method defined in the U.S.Army Corps of
Engineers Wetland Delineation Manual(Environmental Laboratory, 1987) and the Regional Supplement to the
Corps of Engineers Wetland Delineation Manual:Midwest Region (USACE, 2010). Delineation data points and
wetland boundaries were recorded across the site and associated shapefiles are available upon request.
2.2 Delineation of Streams &Tributaries
For the purposes of this report,streams&tributaries are characterized by having both a defined bed and bank,
and an ordinary high water mark (OHWM).
2.3 Ditches
Any areas identified as ditches within the project area were specifically designed and are maintained to
promote roadway or other drainage. Ditches exhibiting wetland characteristics (hydrophytic vegetation,
Natural Resources Inventory Page 2
October 2019
Impact7G,Inc.
hydric soils, or wetland hydrology), that were constructed in upland areas are not identified as wetlands or
other waters of the U.S. For the purposes of this report, ditches or portions of ditches meeting wetland
characteristics that were likely constructed in pre-existing wetlands and/or intersect existing wetlands, or
other waters of the U.S., are identified as wetlands. Furthermore, ditches are distinguished herein from
streams or tributaries if they lack a defined bed and bank, ordinary high water mark,and perennial flow.
3.0 Discussion of Findings
Wetland delineation fieldwork was completed on 9/23/2019,by:
Will Downey,Certified Wetland Delineator
Tyler Dursky,Certified Wetland Delineator
3.1 Current Conditions
The eastern half of the investigation area consists of row-crop agriculture, in soybeans at the time of
delineation. Aerial imagery dating back to 2005 indicates frequent soil disturbance, intensive row-crop
agriculture,and grading activities within the eastern,currently agricultural,area.
In the central portion of the investigation area,just to the west of the agricultural field,remnant oak woodland
is present that has persisted since prior to the 1930s.See Figure A: Natura Resource Map.These remnant oaks
provide elevated habitat and ecological value. In the central-to-western portions of the investigation area,the
tree and shrub species present are generally common-to-opportunistic and weedy species with the exception
of a few isolated and scattered oaks.Generally,the trees and shrubs consist of cottonwood (Populus deltoides),
mulberry (Morus alba), silver maple (Acer saccharinum) and box-elder (Acer negundo). Evidence of any
remnant savanna or tall grass prairie herbaceous species was absent throughout the investigation area with
vegetation dominated by common and non-native grasses and annuals.
The western half of the project area is an upper river terrace of the South Skunk River,which contains an old
stream meander channel which no longer conveys water, likely due to past alterations of the upstream
watershed. This old channel is mapped as intermittent stream on USGS Topographic Maps (Figure D) but
currently has no defined bed or bank,and no indicators of an OHWM.
The Palmer Hydrologic Drought Index for the week of the wetland delineation indicates wetter than normal
conditions (moderately moist) for the region.According to the Iowa Environmental Mesonet data available
through Iowa State University,Ames Iowa had received approximately 0.93 inches of total rainfall in the
seven days preceding field work.Within the investigation area most wetland boundaries were delineated
based on geomorphology and landscape position.Soils were also readily distinguishable between upland and
wetland areas.
National Wetland Inventory (NWI) mapping indicates a PEM1A mapped wetland that roughly corresponds to
the existing dry stream channel (Figure E).This NWI mapped wetland is not representative of data observed
in the field, as much of the old stream channel contains insufficient hydrology indicators or non-hydric soils
which do not meet the necessary wetland criteria.The western half of the investigation area has been mapped
as regulatory floodway of the South Skunk River according to NFHL mapping (Figure F). SSURGO soils data
indicates that the western half of the investigation area is predominantly mapped as 40%hydric soils and the
eastern half of the investigation area is mapped as equal parts 5%and 100% hydric soils.
3.2 Wetland Determinations
Within the agricultural field, areas of compaction and ponding water appear to have formed in various
locations over recent years and are developing a diffuse mosaic of wetland features.These areas can generally
be described as closed-to-concave areas with perched surface water or saturation and evidence of extended
Natural Resources Inventory Page 3

ponding during typical wet periods.These areas appear to be developing a mosaic of wetland characteristics
as a result of extensive and repeated disturbance and compaction during the past 5 years, with a history of
disturbance dating back over 15 years. At the time of the delineation, soils within these areas were saturated
from the soil surface to approximately 5-6 inches of depth, resulting in significantly stunted or entirely non-
viable soybean plantings.Due to the stunted and stressed nature of upland plants,vegetation evaluated along
the edge of the wetland area still met wetland indicator "Problematic Hydrophytic Vegetation" (Fox-01).
Adjacent upland areas generally had no soil saturation in the upper 12"and few signs of crop stress (Fox-02).
Typically, U.S.Army Corps of Engineers (USACE) does not take jurisdiction over areas with wetland features
that were accidentally created due to recent grading or other activities resulting in temporary surface water
impoundment,however, if left undisturbed,these areas will likely continue to develop into emergent wetland
areas that may result in jurisdictional wetlands.
Non forested wetlands within the investigation area generally consist of closed depressions within an old
stream channel.The channel no longer conveys water but does provide a catchment for rainwater and a flood
basin during high flow events of the South Skunk River. Most wetland areas within this channel are linear in
shape and were generally dominated by sedge species,violets,and mild water-pepper(Fox-06).Upland areas
within this old channel have hydrophytic vegetation but lack redox features within the upper 12" of the soil
and do not meet the FAC-Neutral Test for vegetation (Fox-03, Fox-05).Adjacent uplands appear to be better
drained due to extent of sand within the soil profile.
One non forested wetland is located at the southwest corner of the investigation area (Fox-04, 0.11 acres)
where the roadway intersects the former stream channel.This area is dominated by Kentucky blue grass and
late goldenrod,with a few white mulberry,silver maple, and cottonwood trees/saplings. Surface water flows
into the wetland area via the old stream channel and a roadside ditch.This ditch has hydrophytic vegetation
but lacks enough wetland hydrology indicators to meet necessary wetland criteria.The wetland is drained by
a road culvert which outflows on the south side of SE 16th Street.

4.0 Regulatory Review
The U.S.Army Corps of Engineers regulates the discharge of dredged or fill materials into all regulated waters
of the United States (WATERS), including wetlands and streams, in Section 404 of the Clean Water Act
(USAEWES Environmental Laboratory, 1987). The process of Jurisdictional Determination, conducted by the
U.S. Army Corps of Engineers, may determine that all or part of the WATERS delineated for this project are
considered regulated. Based on the information provided, it appears this project may involve filling part of
WATERS and therefore may require permits from the Corps of Engineers and the Iowa Department of Natural
Resources prior to beginning work.
The Corps of Engineers normally requires acquisition of a Section 404 permit and mitigation when any
WATERS impact is proposed. In general,there are two types of permits as described below.
Natural Resources Inventory Page 4
Impact7G, Inc. October 2019
Nationwide Permits: A nationwide permit is generally the simplest form of the 404 permits. Wetland loss of
1/2 acre or less is typically permitted under a Nationwide Permit.Stream impacts of 300 linear feet or less are
typically permitted under a Nationwide Permit.This permit often requires preconstruction notification to the
Corps for impacts to as little as 1/10 of an acre or less. Generally,this permit takes 30 to 45 days to obtain.
Individual Permits: An individual permit requires a full public interest review. A Public Notice is distributed
to all known interested persons. After evaluating comments and information received,a final decision on the
application is made. The permit decision is generally based on the outcome of a public interest balancing
process in which the benefits of the project are balanced against the detriments. A permit will be granted
unless the proposal is found to be contrary to the public interest. Processing time usually takes 60 to 120 days
unless a public hearing is required or an environmental statement must be prepared.
During the permitting process for either type of permit, the Corps of Engineers requires that applicants first
establish that impacts to WATERS cannot be avoided. Permit applicants then must demonstrate that
reasonable efforts to minimize impacts to WATERS have been made in the design and construction plans.
Having taken the first two steps, applicants then must provide a plan for compensation, usually through
mitigation, for unavoidable impacts. In general, our experience has been that the Corps requires in-kind
mitigation be done at a minimum ratio of one (1) to one (1) but may require a compensation ratio of 1.5:1 to
2.5:1 (i.e.,two and one-half acres of constructed wetland for every one acre of impact) in some circumstances.
5.0 Conclusions
Impact7G delineated 0.29 acres of non-forested wetland. Farmed areas with recently developing wetland
characteristics due to compaction and recent disturbance were also identified, however, these areas are
typically not considered jurisdictional by U.S.Army Corps of Engineers (USACE)but appropriate coordination
is advised.
If proposed activities will impact these areas, consultation with USACE and the Iowa Department of Natural
resources is strongly recommended
Other environmentally sensitive natural resources present within the investigation area include several large
native oak trees that provide elevated habitat and ecological value.
This report has been prepared for the exclusive use of our client, and for specific application to the project
discussed. To the best of my knowledge the above statements,attachments,including those labeled and identified
as enclosures, and all conclusions are true, accurate,and based on current environmental principles and science.
No warranties,either expressed or implied,are intended or made. In the event that changes in the nature, design
or location of the project as shown are planned, the conclusions and recommendations contained on this form
shall not be considered valid unless Impact7G, Inc. reviews the changes and either verifies or modifies the
