The Village shall grant a stormwater permit which may impose terms and conditions in accordance with Chapter
313, Stormwater: Illicit Discharge and Connection, illicit discharge elimination plan (IDEP) and this chapter and which shall be granted only upon compliance with each of the following requirements:
A. The developer has submitted a drainage plan for all drainage complying
with all requirements of this chapter; and
B. The drainage plan contains a description of an adequate, temporary
stormwater retention or system to prevent construction site stormwater
runoff, satisfying all the requirements of this chapter, and the developer
has obtained a soil erosion permit, if necessary; and
C. If it can be demonstrated that the drainage will be materially improved,
the following standards will not apply if the developer provides:
(1) A permanent on-site drainage plan and a stormwater management facility
complying with the Village of Spring Lake Standards and Specifications
and the Village of Spring Lake Performance and Design Standards adopted
by the Village; and
(2) The developer has paid or deposited the stormwater permit review
fee pursuant to this chapter, if applicable; and
(3) The developer has paid or posed the applicable financial guarantee
pursuant to this chapter, if applicable; and
(4) The developer provides all easements necessary to implement the approved
drainage plan and stormwater management facility and to otherwise
comply with all of the provisions of this chapter. All easements shall
be acceptable to the Village in form and substance and shall be recorded
with the County Register of Deeds; and
(5) The drainage plan is designed in conformity with the Village of Spring
Lake Performance and Design Standards adopted by the Village as part
of this chapter; and
(6) All stormwater runoff facilities shall be designed in accordance
with the Village design criteria as set by the stormwater manager;
and
(7) The developer provides the required maintenance agreement for routine,
emergency, and long-term maintenance of all stormwater management
facilities. This agreement shall be in compliance with the approved
drainage plan and this chapter; and
(8) The maintenance agreement shall be acceptable to the Village in form
and substance and shall be recorded with the County Register of Deeds,
if deemed necessary by the Zoning Administrator.
During the site plan approval process, the developer shall provide
a drainage plan to the Village for review and approval. The drainage
plan shall identify and contain all of the following:
A. The location of the development site and water bodies that will receive
stormwater runoff;
B. The existing and proposed typography of the development site, including the alignment and boundary of the natural drainage courses, with contours having a maximum interval of two feet (using USGS datum). The information shall be superimposed on the pertinent Ottawa County soil map. This provision does not apply to developments not required as stated in §§
320-5 and
320-6 of this chapter;
C. The development tributary area to each point of discharge from the
development;
D. Calculations for the final peak discharge rates of a 100-year, twenty-four-hour storm as determined by the Village Engineer and also if permitted by the Planning Commission per Article
X of this chapter;
E. Calculations for any facility or structure size and configuration;
F. A drawing showing all proposed stormwater runoff facilities with
existing and final grades;
G. The sizes and locations of upstream and downstream culverts serving
the major drainage routes flowing into and out of the development
site. Any significant off-site and on-site drainage outlet restrictions,
other than culverts, should be noted on the drainage map;
H. An implementation plan for construction and inspection of all stormwater
management facilities necessary to the overall drainage plan, including
a schedule of estimated dates for completing construction of the stormwater
runoff facilities shown on the plan and an identification of the proposed
inspection procedures to ensure that the stormwater management facilities
are constructed in accordance with the approved drainage plan;
I. A plan to ensure the effective control of construction stormwater
runoff and sediment tracking onto roadways and how often roadways
will be cleaned;
J. Drawings, profiles, and/or specifications for the construction of
stormwater management facilities reasonably necessary to ensure that
stormwater runoff will be drained, stored, or otherwise controlled
in accordance with this chapter;
K. A maintenance agreement, in form and substance acceptable to the
Village, as applicable, if determined necessary by the Zoning Administrator,
for ensuring maintenance of any privately owned stormwater management
facilities. The maintenance agreement shall include the developer's
written commitment to provide routine, emergency, and long-term maintenance
of the facilities in perpetuity and, in the event that the facilities
are not maintained in accordance with the approved drainage plan,
the agreement shall authorize the Village to maintain an on-site stormwater
management facility as reasonably necessary, at the developer's
expense;
L. The name of the engineering firm and the professional engineer that
designed the drainage plan and that will inspect final construction
of the stormwater runoff facilities, unless the use of an engineer
is waived by the Zoning Administrator;
M. All design information should be compatible with the county geographic
information system.
Prior to making any earth change on a development site regulated
by this chapter, the developer shall first obtain a soil erosion permit
from the County Drain Commissioner issued in accordance with Part
91 of Act No. 451 of the Public Acts of 1994, as amended, if one is
required. The developer shall install stormwater management facilities
that conform to the Village's stormwater performance and design
standards and shall phase the development activities so as to prevent
construction site stormwater runoff and off-site sedimentation. During
all construction activities on the development site, the Village Manager,
engineer, Zoning Administrator, or his or her designees, may inspect
the development site to ensure compliance with the approved construction
site runoff controls.
No certificate of occupancy shall be issued until stormwater
management facilities have been completed in accordance with the approved
drainage plan; provided, however, the Village may issue a temporary
certificate of occupancy if an acceptable letter of credit or other
financial guarantee has been submitted to the Village Zoning Administrator,
for the timely and satisfactory construction of all stormwater management
facilities and site grading in accordance with the approved drainage
plan.
Stormwater management facilities, after construction and approval,
shall be maintained in good condition, in accordance with the approved
drainage plan, and shall not be subsequently altered, revised or replaced
except in accordance with the approved drainage plan, or in accordance
with approved amendments or revisions in the plan.
