UDO AMENDMENT PACKET NOTES:
The following packet details staff's proposed modifications to existing regulations to incorporate
additional opportunities to modify allowable impervious surface area through the installation and
an infiltration based stormwater feature.
As the number of affected pages/sections of the existing UDO are being modified with this
proposal staff has divided the proposed amendments into the following color coded
classifications:
• Red Underlined Text: Denotes new, proposed text, that staff is suggesting be
added to the UDO
• Red St fike4weug Text.: Denotes existing text that staff is proposing to delete
• Underlined Green Bold Text: Denotes new, proposed text, recommended by the
County Planning Director.
• Blue Bold Underlines Text: Denotes language recommended by the County
Planning Board at its June 3, 2015 meeting.
Staff has included footnotes within the amendment package to provide additional
information/rationale concerning the proposed amendments to aid in your review.
Only those pages of the UDO impacted by the proposed modification(s) have been included
within this packet. Some text on the following pages has a large "X" through it to denote that
these sections are not part of the amendments under consideration. The text is shown only
because in the full UDO it is on the same page as text proposed for amendment or footnotes from
previous sections `spill over' onto the included page. Text with a large "X" is not proposed for
deletion.
Please note that the page numbers in this amendment packet may or may not necessarily
correspond to the page numbers in the adopted UDO because adding text may shift all of
the text/sections downward.
Users are reminded that these excerpts are part of a much larger document (the UDO) that
regulates land use and development in Orange County. The full UDO is available online at:

1 Staff is editing existing notes throughout the Section to address existing typographical and reference errors. In
the existing text an asterisk(") in certain cases was used to denote information while in other cases it was not.
There was also a [1] used to identify certain watersheds requiring a BMP in the Neuse River Basin. Unfortunately
the watershed overlay districts identified are not in the Neuse River Basin. The proposed amendments address
these issues and clarify the essential information.
z Green bold underlined language added on May 28,2015 to address a concern of the Planning Director.
Specifically lots created through the cluster subdivision process would not be able to take advantage of the
proposal. We also changed out the term'parcel'for'lot'as the term 'lot'is already defined within the UDO.
S Staff is suggesting language mandating a 2 acre minimum lot size, or that the lot was created in accordance with
established density regulations, in order for a parcel within identified watershed overlay districts to request a
modification of impervious surface area through the installation of a stormwater feature.The rationale for the
suggestion is that State regulations currently allow governing bodies to require either a 1 acre minimum lot size,
limited to a 6%impervious surface threshold, or a 2 acre minimum lot size limited to a 12%impervious surface
threshold. In these identified watershed overlay districts the County made a conscious decision to follow the more
restrictive option. We are recommending the condition to ensure those properties subject to a modification
request meet minimum State standards with respect to required lot size. Please refer to Attachment 2 for
additional information on State requirements associated with the establishment and enforcement of impervious
surface thresholds.

accordance with applicable Orange County Erosion Control and State Stormwater regulations. s

4 This references the Section of the UDO where are now recognizing a State provision allowing for the additional
allotment of impervious surface area through the use of specific BMPs.
5 The County enforces land disturbance thresholds for erosion control and stormwater permits,specifically a
certain amount of land disturbance will require the submittal of either an erosion control permit and/or a
stormwater permit application. While a BMP may be installed on a parcel of property as part of a proposed
modification of allowable impervious surface area,the County also enforces standards requiring a BMP on
property being developed for residential purposes based on the proposed amount of land disturbance. This
requirement has nothing to do with the total amount of impervious surface area proposed or any request to
modify same. Land disturbance thresholds vary for each district. We are adding language to the LIDO clarifying
when a BMP is required based on these existing disturbance thresholds.

f21 For non-residential developments a stormwater feature/best management practice(BMP)shall be required in accordance with
applicable local and State standards based on proposed land disturbance and/or a proiect exceeding impervious surface
thresholds as identified herein.
NOTE: Non-residential use impervious acreage limits in watershed with such limits are calculated using the actual amount of
impervious surface for non-residential uses throughout the watershed, not by the overall number of acres of non-residential
parcels located in a particular watershed.
(A) Hillsborough Economic Development District
(1) The Hillsborough Economic Development District is located within Zent
-Unprotected watershed. Within the Hillsborough Economic Deve
District, as designated in the Land Use Element of the Compre sive Plan, the
maximum impervious surface ratio is 50%with detention po s.
4.2.7 Placement o treets, Driveways, and Buildings
(A) Streets, driv ays, and buildings or other structures II be located, to the extent
reasonably poss' e, so as to take full advantage the absorptive capacity of the soils
on which they are to situated and to avoid e following environmentally sensitive
areas:
(1) Stream buffer zones as ed by Section 6.13;
(2) Wetlands as defined the .Army Corps of Engineers;
(3) Land with slope reater than 15%; d
(4) Natural ar s as identified in the Inventory Natural Areas and Wildlife Habitats
of Or e County, NC.
(D) To avoi reating lots that will be difficult to build upon in com 'ance with the standards
of t i Section, the preliminary plan shall show proposed building velopes and
proximate driveway locations for all lots within subdivisions.
(1) A zoning compliance permit shall not be issued for the construction buildings
or driveways outside the areas so designated on the preliminary plan un s the
Planning Director makes a written finding that the proposed location complie
with the provisions of this Section and Sections 6.13 (Stream Buffers) and 6.14
(Stormwater Management).
4.2.8 Modifications of the Impervious Surface Ratio
Modifications of the Impervious Surface Ratios may be requested through one of the following
provisions:
(A) Through variance procedures of the Board of Adjustment, as described in Section 2.10.
Unlike residential development,State regulations require a Stormwater feature for all non-residential projects
exceeding established impervious surface thresholds for the watershed protection overlay district in which the
project is located. This is the reason why language for note 2 within Section 4.2.6 is different from the same note
in Section 4.2.5.
Orange County,North Carolina—Unified Development Ordinance Page 4-10
Article 4: Overlay Zoning Districts
Section 4.2: Watershed Protection
(C) Through approval and recordation of a conservation agreement, as provided in Article 4
of Chapter 121 of the N.C. General Statutes, between Orange County and a land owner
that prohibits development of land in a protected watershed in perpetuity, subject to the
following:
(1) A modification of the required impervious surface ratios may be approved
administratively but only to the extent that additional land in the same watershed
is conserved or protected from development.
(2) The land which will be subject to a conservation agreement must be adjacent to
the land proposed for development and for which a modification of the
impervious surface ratios is sought.
(a) As an example, a person owning a 40,000 square foot lot and subject to
a 12% impervious surface ratio would be limited to 4,800 square feet of
impervious coverage. If the person's plans called for 5,500 square feet
of coverage (a difference of 700 square feet), the recording of a
conservation easement on 5,833 square feet of contiguous property
would satisfy the impervious surface ratio requirements. (12% of 5,833
square feet is 700 square feet.)
(b) The conservation easement shall describe the property restricted in a
manner sufficient to pass title, provide that its restrictions are covenants
that run with the land and, be approved in form by the County Attorney.
(c) The conservation easement shall, upon recording, be in the place of a
first priority lien on the property (excepting current ad valorem property
taxes) and shall remain so unless, with the approval of Orange County, it
is released and terminated.
(d) Orange County shall require the priority of the conservation easement to
be certified by an attorney-at-law, licensed to practice law in the State of
North Carolina and approved to certify title to real property.
(e) Orange County approval of a release or termination of the conservation
agreement shall be declared on the document releasing or terminating
the agreement. The document shall be signed by the Orange County
Manager, upon approval of the Board of County Commissioners. No
such document shall be effective to release or terminate the
conservation agreement until it is filed for registration with the Register of
Deeds of Orange County.
(C) Through the installation of a stormwater feature, consistent with the minimum design
standards as detailed within the State BMP Manual.
(1) The proposed feature must be recognized by Orange County and the State as
allowing for an increase in impervious surface area through an infiltration
stormwater feature.
(2) Under no circumstances may impervious surface area be increased by more
than 3% of the total allowable area on the subiect parcel through this process.
(3) The property owner shall provide a stormwater assessment, completed by a
licensed engineer, of the current property identifying its infiltration rates and
carrying capacity as well as a comprehensive soil assessment for the property.
(4) The development/design of the feature shall be in accordance with established
design criteria as embodied within the State stormwater manual and shall be
completed by a licensed engineer with expertiese in stormwater management. s
Additional allowable impervious surface area shall be based on the soil
s Language added to address OWASA concern(s)over the UDO explicitly requiring a licensed engineer,with
expertise in stormwater management,completed the design on the BMP.

maintenance, inspection, and upkeep of the approved BMP in accordance with
County and State regulations.
The Planning Director shall cause an analysis to be made of the agreement by
qualified representatives of the Cointy and other agencies or officials as
appropriate. Once approved the document shall be recorded in the Orange
County Registrar of Deeds office.
The property owner assumes all financial and legal responsibility for the

and file with the County a bond or other form of acceptable security, to
cover the cost of removal of a BMP, and any additional impervious surface
area installed as the result of its approval, in the event the BMP is failed to
be maintained in accordance with the recorded operations agreement. The
amount of the bond shall be 110%of the estimated cost of removing the
feature and impervious surface area as certified by a licensed professional
engineer or surveyor.

0 The County Attorney's office has expressed concern over the language with this Section,specifically there is a
concern over liability issues due to the lack of defined standards associated with said review. Unfortunately we
have received numerous review comments from our planning partners(i.e.OWASA,the Towns, etc.)requesting
additional level of detail. While we understand the nature of the Attorney's concern staff is finding it difficult to
make everyone comfortable.
