A.
Recognition of Natural Resource Features. This Ordinance
recognizes that landforms, parcel size and shape, and natural resource
features vary from site to site and that development regulations must
take into account these variations. The maximum density or intensity
of use allowed in any zoning district is controlled by the various
district standards set forth for each of the various zoning districts
of this Ordinance.
B.
When Natural Resource Protection and Site Intensity
and Capacity Calculations Are Required. Natural resource protection
is required for all development and the site intensity and capacity
calculations set forth in this Division shall be made for each parcel
of land to be used or built upon in the City of Franklin including
all new Certified Survey Maps, Preliminary Plats, condominiums, multiple-family
residential developments, all nonresidential development, and as may
be required elsewhere in this Ordinance except as excluded under the
provisions of § 15-3.0501C. of the Unified Development Ordinance.
C.
Exclusions (When Natural Resource Protection and
Site Intensity and Capacity Calculations Are Not Required). Natural
resource protection shall not be required and the site intensity and
capacity calculations set forth in this Division shall not be required
for the construction of single-family and two-family residential development
located on non-divisible existing lots of record within existing platted
Subdivisions (with an approved Final Plat), Certified Survey Maps,
and Condominiums existing on August 1, 1998, the effective date of
this Ordinance or for which a natural resource protection plan and
site intensity capacity calculations were filed at the time of division
after August 1, 1998. A Natural Resource Protection Plan shall not
be required with an application for certified survey map approval
where a single property zoned I-1 Institutional District is divided
as a result of a public work of improvement for street extension purposes,
with related public sanitary sewer and water work for which special
assessment was made, into two or more parcels through the property
fee acquisition by the City for the extension of the public street.
The foregoing exclusions from Natural Resource Protection Plan submission
requirements for certified survey map applications shall only be available
upon the conditions that in lieu of the Plan submission requirement,
the certified survey map application shall be accompanied by the "best
available information" as to the existence of any natural resource
features, such as existing topographical maps, wetland inventories,
and other such inventories as may be available; and that a Natural
Resource Protection Plan must be submitted upon any further development
of any portion of the mapped property. A Natural Resource Protection
Plan shall also not be required with an application for certified
survey map approval where lots are being created from a larger surrounding
parcel, with the larger in area in relation to the lots created remnant
parcel being vacant, or already having being developed by the existence
of a principal structure and not being the subject of current further
development application, and with the only natural resources within
the map area being upon the remnant parcel and being more than 500
feet away from the lots being created. The foregoing exclusion from
Natural Resource Protection Plan submission requirement for certified
survey map applications shall only be available upon the conditions
that i) in lieu of the Natural Resource Protection Plan submission
requirement, the Certified Survey Map application shall show upon
its face the existence of any natural resource features, as identified
in § 15-4.0102, located on the parcels of the Certified
Survey Map based upon the "best available" information; (ii) that
a Natural Resource Protection Plan must be submitted upon any further
development of the "remnant" parcel; and iii) the following note shall
be placed upon the face of such Certified Survey Map: "The Natural
Resource Features identified herein are not based upon field surveys.
In the event of further land division or development of a parcel herein
with any such Natural Resource Feature, a complete NRPP with field
surveys is required for said parcel" For the purposes of this section,
the Zoning Administrator shall not require that the "best available"
information be a "first source" of information, as identified in § 15-4.0102A.,
B., C., D., and G. Notwithstanding any other provision of this Ordinance,
natural resource protection and any such related Natural Resource
Protection Plan, shall not be required and the site intensity and
capacity calculations set forth in this Division shall not be required
for any accessory use structure or accessory use development or for
an addition or modification to an existing principal structure development
which does not increase the existing developed structure and impervious
surface area upon the parcel by more than 50% or 2,500 square feet,
whichever is smaller, where natural resource feature(s) are not within
100 feet of the area to be disturbed by the new development, upon
a parcel supporting an existing principal structure with an existing
principal use; determination as to whether natural resource features
are within 100 feet of the area to be disturbed, the boundaries of
which shall be clearly identified within application materials, shall
be made by the City Engineer or designee; however, if any resources
identified by the Southeastern Wisconsin Regional Planning Commission
in PR 176 or in PR 42, as may be amended from time to time, as Primary
or Secondary Environmental Corridor and/or Isolated Natural Resources
Area, are located on the site by the City Engineer or designee, but
are outside of 100 feet of the area to be disturbed, a written plan
shall be provided by the applicant detailing the protective measures
that will be implemented to prevent such natural resource feature(s)
adverse impacts, which shall be subject to approval by the Plan Commission
and shall be installed as may be provided on site as detailed within
the plan as a condition of application approval. A Natural Resource
Protection Plan (and related requirements, such as the submission
of conservation easements, etc.) shall not be required with an application
for certified survey map approval for the purpose of providing additional
land to an adjoining tax incremental district mixed-use development
including industrial and commercial uses, where lots are being created
from a parcel or parcels, upon which there exists an established residential
dwelling building use, such established use parcel or parcels not
being the subject of current further development application, for
such remaining established residential dwelling building use parcel
or parcels only, provided with regard to such remaining established
residential dwelling building use parcel or parcels that: i) in lieu
of the Natural Resource Protection Plan submission requirement, the
Certified Survey Map application shall show upon its face the existence
of any natural resource features, as identified in § 15-4.0102,
located on the parcels of the Certified Survey Map based upon the
"best available" information; (ii) that a Natural Resource Protection
Plan must be submitted upon any further development of the "remaining
established residential dwelling building use parcel or parcels";
and iii) the following note shall be placed upon the face of such
Certified Survey Map: "The Natural Resource Features identified herein
upon lot[s] [number[s]] are not based upon field surveys. In the event
of further land division or development of lot[s] [number[s]] with
any such Natural Resource Feature, a complete NRPP with field surveys
is required for said parcel."
[Amended 1-21-2020 by Ord. No. 2020-2414]
The base site area shall be calculated as indicated in Table
15-3.0502 for each parcel of land to be used or built upon in the
City of Franklin as referenced in § 15-3.0501 of this Ordinance.

and lying within the base site area (as defined in § 15-3.0502),
shall be measured relative to each natural resource feature present.
The actual land area encompassed by each type of resource is then
entered into the column of Table 15-3.0503 titled "Acres of Land in
Resource Feature." The acreage of each natural resource feature shall
be multiplied by its respective natural resource protection standard
(to be selected from Table 15-4.0100 of this Ordinance for applicable
agricultural, residential, or nonresidential zoning district) to determine
the amount of resource protection land or area required to be kept
in open space in order to protect the resource or feature. The sum
total of all resource protection land on the site equals the total
resource protection land. The total resource protection land shall
be calculated as indicated in Table 15-3.0503.

Note: In conducting the calculations in Table 15-3.0503, if
two or more natural resource features are present on the same area
of land, only the most restrictive resource protection standard shall
be used. For example, if floodplain and young woodlands occupy the
same space on a parcel of land, the resource protection standard would
be 1.0 which represents the higher of the two standards.
