ORDINANCE NO. ____
AN ORDINANCE CREATING SUBPARAGRAPH (e) OF
PARAGRAPH (5) OF SECTION 6-4-12 OF CHAPTER 6-4 OF
TITLE 6 OF THE ROCHESTER CODE OF ORDINANCES
RELATING TO STORMWATER MANAGEMENT CRITERIA
FOR PERMANENT FACILITIES AND BMPS.
THE COMMON COUNCIL OF THE CITY OF ROCHESTER ORDAINS:
Section 1. Subparagraph (e) of Paragraph (5) of Section 6-4-12 of Chapter 6-4 of Title
6 of the Rochester Code is hereby created to read as follows:
Sec. 6-4-12. – Stormwater management criteria for permanent facilities and BMPs.
(5) Off-site water quality treatment. For non-linear projects, where the water quality
volume cannot cost effectively be treated on the site of the original construction
activity, the owners of the construction activity are required to identify locations
where off-site treatment projects can be completed. If the entire water quality
volume is not addressed on the site of the original construction activity, the
remaining water quality volume must be addressed through off-site treatment
and, at a minimum, ensure the requirements of the items below are met:
a. The city engineer must ensure off-site treatment project areas are selected in
the following order of preference:
1. Locations that yield benefits to the same receiving water that receives runoff
from the original construction activity.
2. Locations within the same department of natural resource (DNR) catchment
area as the original construction activity.
3. Locations in the next adjacent DNR catchment area up-stream.
4. Locations anywhere within the city's jurisdiction.
b. Off-site treatment projects must involve the creation of new structural
stormwater BMPs or the retrofit of existing structural stormwater BMPs, or the
use of a properly designed regional structural stormwater BMP.
c. Off-site treatment projects must involve the creation of new structural
stormwater BMPs or the retrofit of existing structural stormwater BMPs, or the
use of a properly designed regional structural stormwater BMP.
d. Off-site treatment projects must be completed no later than 24 months after the
start of the original construction activity. If the city engineer determines more
time is needed to complete the treatment project, the reason(s) for the delays
1
and schedule(s) for completing the project must be provided in the annual
report.
e. Stormwater Water Quality Treatment Credit Transfer Program.
1. All off-site stormwater water quality treatment projects required or
approved under this section must be implemented through the City's
adopted Stormwater Water Quality Treatment Credit Transfer Program
(Program) and comply with the Council-adopted Stormwater Water
Quality Treatment Credit Transfer Policy (Policy), applicable
implementation procedures, and state and federal regulatory
requirements.
2. Transfer ratios. All SWQT credit transfers must apply the transfer
ratios established in the Council-adopted Policy. The transfer ratio
accounts for the location of the credit-generating site relative to the
receiving development and requires additional treatment capacity to
provide a net environmental benefit when compared with on-site
treatment. The applicable transfer ratio shall be determined and
applied in accordance with the Policy.
3. Stormwater water quality treatment agreements and associated credit
transfers approved by the City before January 1, 2027 may continue
under the terms and conditions of their original approvals, including
any applicable transfer ratio. If a property is redeveloped or the
stormwater treatment system is modified in a manner requiring new or
amended stormwater approvals, the project must comply with the
requirements of this section and the Policy.
Section 2. This ordinance shall become effective from and after its publication.
