A.
For sites that disturb less than one (1) acre unless otherwise exempted under Section 407.030, the owner/developer/contractor must provide a sketch plot plan indicating the overall layout of buildings and other impervious areas, indicate flow direction with arrows, show the location of any existing or proposed drainage structures, and show the location of construction site best management practices. This plan does not necessarily need to be prepared by a registered professional engineer. The calculations for the sizing of any new or modified storm sewers and any other permanent stormwater best management practices shall be prepared by a registered professional engineer.
B.
For
all sites resulting in land disturbance of one (1) acre or greater,
each developer/owner subject to this Chapter shall submit to Excelsior
Springs Community Development Department for review and approval a
stormwater management plan as provided herein.
[Ord. No. 14-04-09 §1, 4-21-2014]
All applicants shall participate in a pre-application meeting
with City of Excelsior Springs staff to discuss potential approaches
for stormwater design and opportunities to use design techniques to
reduce runoff rates, volumes, and pollutant loads. During the pre-application
meeting, the applicant shall provide information regarding design
considerations as outlined in the Excelsior Springs Development Guide.
[Ord. No. 14-04-09 §1, 4-21-2014]
If the developer/owner only desires to obtain a grading permit
for purposes of clearing and rough grading, they may do so upon approval
of the preliminary grading plan, erosion and sediment control plan
and a stormwater pollution prevention plan.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Submittal. A stormwater management design plan containing
all appropriate information as specified in this Chapter and outlined
in KC-APWA 5100, KC-APWA 5600 and MARC BMP Manual shall be submitted
with the final subdivision plat, final development plan, final site
plan, construction plan, or any other land development plan subject
to this Chapter.
B.
Application Requirements. The stormwater management design
plan submittal shall contain:
1.
A completed grading/stormwater permit application form provided by
Excelsior Springs Public Works;
2.
The fee(s) according to the adopted fee schedule;
3.
A stormwater management construction plan and associated calculations
that satisfies the requirements of this Section and the KC-APWA 5100,
KC-APWA 5600 and the MARC BMP Manual; and
4.
A stormwater facilities and/or BMP maintenance plan and maintenance
agreement where applicable.
C.
Stormwater Management Design Plan Content. The stormwater
management design plan shall contain maps, charts, graphs, tables,
photographs, narrative descriptions, explanations, calculations, citations
to supporting references, a record of all major permit decisions,
and other information as may be necessary for a complete review of
the plan, and as specified in the KC-APWA 5100, KC-APWA 5600 and the
MARC BMP Manual.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Review for Completeness of Plan. City of Excelsior Springs
staff will perform a preliminary review to determine if the application
is complete. Upon completion of this review, staff may forward the
submittal to a third party consulting review engineer for determination
of whether the plans meet the ordinance requirements. Any third party
review is done at the expense of the owner/developer.
B.
Substantive Changes to Plan. No substantive changes shall
be made to an approved plan without review and written approval by
the Director. The City may request additional data with a plan amendment
as may be necessary for a complete review of the plan and to ensure
that changes to the plan will comply with the requirements of this
Chapter.
C.
Expiration of Plan Approval. The stormwater management construction
plan's approval expires one year from the date of approval unless
work has begun on the site or an extension request from the owner
or design engineer has been received by the Director. If the stormwater
management construction plan approval expires and is not granted an
extension, the applicant shall file with the Director for reapproval
of the stormwater management construction plan.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Approval Of Other Permits. Unless exempt, no grading/stormwater
permit or building permit shall be issued for land development without
approval of a stormwater management construction plan.
B.
Coordination With Other Plans. Approval of the stormwater
management construction plan shall be coordinated by Excelsior Springs
Public Works with approval of an erosion and sediment control or construction
stormwater plan with regard to the location, schedule, and/or phasing
for temporary and permanent stormwater management measures. If natural
drainage features or other natural areas are to be preserved, then
these areas must be shown and measures provided for their protection
on both the erosion and sediment control plan and the stormwater management
construction plan. If other elements of the stormwater management
construction plan utilize soils, vegetation, or other natural features
for infiltration or treatment, then these areas must be shown on the
erosion and sediment control plan and measures provided for their
protection during construction.
C.
Other Permits Or Approvals May Be Needed. Approvals issued
in accordance with this Chapter do not relieve the applicant of responsibility
for obtaining all other necessary permits and/or approvals from other
federal, state, and/or local agencies. If requirements vary, the most
restrictive shall prevail. These permits may include, but are not
limited to: applicable state and federal permits for stream and wetland
impacts and applicable dam safety permits. Applicants are required
to show proof of compliance with these regulations before the City
of Excelsior Springs will issue a grading/stormwater permit or building
permit.
D.
Stormwater Measures Within Designated Flood Hazard Areas. Construction of stormwater measures or facilities within a Federal Emergency Management Agency (FEMA) designated floodplain or floodway shall be avoided to the extent possible. When this is unavoidable, all stormwater BMP construction shall be in compliance with all applicable requirements of the Floodplain Management Ordinance in Chapter 401 of the City Code.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Prior
to approval by Excelsior Springs Public Works of a stormwater management
construction plan, each owner shall submit a maintenance agreement
and maintenance plan in accordance with the following:
1.
Responsible party. The owner shall be responsible
for the operation and maintenance of such measures and shall pass
such responsibility to any successor owner.
2.
Requirement for maintenance agreement and plan. If
a stormwater management construction plan requires structural or nonstructural
measures, the owner shall execute a stormwater maintenance agreement
prior to Excelsior Springs Public Works granting final approval for
the plan, or any plan of development or other development for which
a permit is required under this Chapter. The agreement shall be recorded
in the office of the Clay or Ray County Recorder of Deeds (whichever
county the parcel lies in) and shall run with the land.
3.
Required elements for maintenance agreement and plan. The stormwater maintenance agreement shall be in a form approved
by the City, and shall, at a minimum:
a.
Designate responsible party. Designate for the
land development the owner, governmental agency, or other legally
established entity (responsible party) which shall be permanently
responsible for maintenance of the structural or non-structural measures
required by the plan.

for such maintenance to successors in title.
c.
Right of entry for stormwater authority. Grant
Excelsior Springs Public Works and its representatives the right of
entry for the purposes of inspecting all stormwater facilities and
BMPs at reasonable times and in a reasonable manner. This includes
the right to enter a property when Excelsior Springs Public Works
has a reasonable basis to believe that a violation of this Chapter
is occurring or has occurred and to enter when necessary for correction
of a violation of this Chapter.
d.
Maintenance plan. Ensure the continued performance
of the maintenance obligations required by the plan and this Chapter
through a maintenance plan (which shall be an attachment to the actual
maintenance agreement). The plan shall include a list of inspection
and maintenance tasks, a schedule for routine inspection and maintenance,
actions to be taken when maintenance is required, and other items
as needed to ensure ongoing operation of the facility.
