For any of the activities regulated by this
chapter, the preliminary or final approval of subdivision and/or land
development plans, the issuance of any building or occupancy permit,
or the commencement of any earth disturbance may not proceed until
the applicant or his/her agent has received written approval of a
drainage plan from the municipality and an adequate erosion and sediment
control plan review by the Conservation District.
A.
Exemptions. The following land use activities are
exempt from the drainage plan submission requirements of this chapter:
(1)
Use of land for gardening for home consumption.
(2)
Agriculture when operated in accordance with a Conservation
Plan or Erosion and Sediment Control Plan (E & S) found adequate
by the Conservation District.
(3)
Forest management operations which are following the Department of Environmental Protection's management practices contained in its publication "Soil Erosion and Sedimentation (E & S) Control Guidelines for Forestry" and are operating under an approved E & S Plan and must comply with stream buffer requirements in § 92-10 and floodplain management requirements.
(4)
Impervious surface. Any regulated activity that has
less than 5,000 square foot of impervious surface and/or meets the
following exemption criteria is exempt from the plan submittal provisions
of this chapter. These criteria shall apply to the total development
even if development is to take place in phases. The date of the original
Brodhead or McMichaels municipal ordinance adoption shall be the starting
point from which to consider tracts as "parent tracts" in which future
subdivisions and respective impervious area computations shall be
cumulatively considered. Impervious areas existing on the parent tract
prior to adoption of this chapter shall not be considered in cumulative
impervious area calculations for exemption purposes.
B.
Additional exemption criteria includes:
(1)
Exemption responsibilities. An exemption shall not
relieve the applicant from implementing such measures as are necessary
to protect the public health, safety, and property. An exemption shall
not relieve the applicant from providing adequate stormwater management
for regulated activities to meet the purpose of this chapter; however,
drainage plans will not have to be submitted to the municipality.
(2)
This exemption shall not relieve the applicant from meeting the special requirements for watersheds draining to exceptional value (EV) waters and source water protection areas (SWPA): requirements for nonstructural project design sequencing (§ 92-9) water quality and streambank erosion (§ 92-10), and groundwater recharge (§ 92-11).
(3)
Drainage problems. If a drainage problem is documented
or known to exist downstream of, or expected from the proposed activity,
then the municipality may require a drainage plan submittal.
(4)
Parent tracts. Ordinance criteria shall apply to the
total development even if development is to take place in phases.
The date of the municipal ordinance adoption from the original McMichaels
Creek and Brodhead Creeks Act 167 Plans shall be the starting point
from which to consider tracts as "parent tracts" in which future subdivisions
and respective impervious area computations shall be cumulatively
considered.
The drainage plan shall consist of a general description of the project including sequencing items described in § 92-9, calculations, maps and plans and § 92-16, Consumptive use tracking report.

or noncompliant with the stormwater management plan, the Municipal
Engineer shall forward a letter to the Municipal Secretary with a
copy to the applicant citing the reason(s) and specific ordinance
sections for the inconsistency or noncompliance. Inconsistency or
noncompliance may be due to inadequate information to make a reasonable
judgment as to compliance with the stormwater management plan. Any
drainage plans that are inconsistent or noncompliant may be revised
by the applicant and resubmitted consistent with this chapter. The
Municipal Secretary shall then notify the developer of the Municipal
Engineer's findings. Any disapproved drainage plans may be revised
by the developer and resubmitted consistent with this chapter.
E.
For regulated activities specified in § 92-4 of this chapter, which require a building permit, the Municipal Engineer shall notify the Enforcement Officer in writing whether the drainage plan is consistent with the stormwater management plan and forward a copy of the approval/disapproval letter to the applicant.

H.
No municipal permits shall be issued for any regulated activity specified in § 92-4 of this chapter if the drainage plan has been found to be inconsistent with the stormwater management plan, as determined by the Municipal Engineer, or without considering the comments of the Municipal Engineer shall be issued. All required permits from PaDEP must be obtained prior to issuance of a building permit.
I.
The applicant shall be responsible for completing
record drawings of all stormwater management facilities included in
the approved drainage plan. The record drawings and an explanation
of any discrepancies with the design plans shall be submitted to the
Municipal Engineer for final approval. In no case shall the municipality
approve the record drawings until the municipality receives a copy
of an approved declaration of adequacy and/or highway occupancy permit
from the PennDOT District Office, NPDES permit, and any applicable
permits or approvals, from PaDEP or the Conservation District. The
above permits and approvals must be based on the record drawings.
J.
The municipality's approval of a drainage plan shall be valid for a period not to exceed five years, commencing on the date that the municipality signs the approved drainage plan. If stormwater management facilities included in the approved drainage plan have not been constructed, or if constructed, and record drawings of these facilities have not been approved within this five-year time period, then the municipality may consider the drainage plan disapproved and may revoke any and all permits. Drainage plans that are considered disapproved by the municipality shall be resubmitted in accordance with § 92-23 of this chapter.
A.
A modification to a drainage plan under review by the municipality for a development site that involves a change in stormwater management facilities or techniques, or that involves the relocation or redesign of stormwater management facilities, or that is necessary because soil or other conditions are not as stated on the drainage plan as determined by the Municipal Engineer, shall require a resubmission of the modified drainage plan consistent with § 92-20 of this chapter and be subject to review as specified in § 92-21 of this chapter.
