Section 4. The Chanhassen City Code is amended by adding Section 20-921 to read as
follows:
Sec. 20-921 —Pervious Pavement
Properly designed, installed, and maintained pervious pavements have the capacity to allow for
stormwater detention and/or infiltration. When not properly designed, installed, and maintained
pervious pavements fail to facilitate the detention and/or infiltration of stormwater. Additionally,
pervious pavements contribute to the creation of heat islands and do not provide the same surface
water management benefits as native vegetative cover. For these reasons, it is necessary to
regulate the lot coverage, design, installation, and maintenance of these systems.
1) Lot Coverage: Pervious pavements are considered to constitute lot coverage; however,
when built to the standards espoused in this section they do not constitute impervious
surfaces. Systems not built to the standards espoused in this section are considered to
constitute impervious surfaces.
2) Location Restrictions:
a. Pervious pavements may not be installed in areas where trash or garbage
receptacles will be stored.
3) Design and Installation:
a. A building permit is required for the instillation of pervious pavement systems.
b. Pervious pavement systems must be designed to provide for rate and volume
control for the first half inch (0.5") of treatment area and follow the current
version of The City of Chanhassen Standard Specification and Detail Plates.
Treatment area includes the total square footage of the pervious pavement system
plus the total square footage of impervious surface draining directly to the
pervious pavement system.
c. To meet the city's definition of pervious pavement the system must: 1) be
designed in compliance with standards established by the Interlocking Concrete
Pavement Institute (ICPI); 2) be installed by an ICPI certified installer; and, 3) be
designed to meet or exceed the standards listed in paragraph (b).
d. The City Engineer may permit pervious pavement technologies other than
permeable interlocking concrete pavers, so long as the City Engineer determines:
1) they are functionally equivalent or better; 2) the system is designed in
compliance with accepted guidelines and is installed by an appropriately certified
installer; and, 3) the system will meet or exceed the standards listed in paragraph
(b)•
4) Maintenance:
a. The owner of a pervious paver system must enter into a maintenance agreement
with the city to ensure the system performs as designed in perpetuity. This
agreement must conform to the manufactures guidelines, and stipulate the
frequency and type of maintenance to be performed.
District restrictions:
a. Planned Unit Developments Residential Districts (PUDR) are limited to the lot
coverage specified by their ordinance and/or compliance table. For PUDRs
created before June 11, 2018 the terms hardcover, hard surface, impervious
surface, and similar phrases shall be understood to mean lot cover inclusive of
both pervious pavements and impervious surfaces, and in no circumstance shall
the failure of the ordinance or compliance table to mention pervious pavements be
understood to mean that pervious pavements are not subject to the lot cover,
hardcover, hardscape, or similarly identified limits that govern the PUDR.
b. Shoreland Management District restricts properties zoned Single Family
Residential District (RSF) to 25 percent lot coverage.
5)
Section 5. This ordinance shall be effective as of the 1" day of August, 2018.
PASSED AND ADOPTED this 25a' day of June, 2018 by the City Council of the City of
