A. 
Any regulated activity that meets the exemption criteria in Appendix A of this Part 1[1] is exempt from the stormwater management site plan preparation provisions of this Part 1. This criteria shall apply to the total development even if development is to take place in phases. The date of any previously adopted stormwater management ordinance or the date of municipal adoption of this Part 1, whichever is older, shall be the starting point from which to consider tracts in which future subdivision and respective impervious area computations shall be cumulatively considered. Exemption shall not relieve the applicant from providing adequate stormwater management to meet the purpose of this Part 1.

B. 
Land disturbance associated with existing one- and two-family dwellings, subject to conditions described in Appendix A of this Part 1.[2]

C. 
Agricultural activities when operated in accordance with a conservation plan or erosion and sedimentation control plan found adequate by the Conservation District. The agricultural activities, such as growing crops, rotating crops, tilling of soil and grazing animals and other such activities, are specifically exempt from complying with the requirements of this Part 1.
D. 
Forest management operations which are following the PADEP management practices contained in its publication "Soil Erosion and Sedimentation Control Guidelines for Forestry" and are operating under an erosion and sedimentation control plan.
All activities regulated by § 410-4 of this Part 1 and governed by the Act 167 Plan shall prepare a stormwater management site plan. The stormwater management site plan shall consist of all applicable calculations, maps and plans. A note on the maps shall refer to the associated computations and erosion and sedimentation control plan by title and date. The cover sheet of the computations and erosion and sedimentation control plan shall refer to the associated maps by title and date. All stormwater management site plan materials shall be submitted to the municipality or its designee in a format that is clear, concise, legible, neat and well organized. Incomplete submissions shall be returned to the applicant within seven days, along with a statement that the submission is incomplete, and stating the deficiencies found. Otherwise, the application shall be deemed accepted for filing as of the date of submission. Acceptance shall not, however, constitute a waiver of any deficiencies or irregularities.

[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
For the purpose of complying with this Part 1, the steps below shall be followed for stormwater management site plan submission. For any activities that require a PADEP joint permit application and regulated under PADEP's rules and regulations, 25 Pa. Code Chapter 105, Dam Safety and Waterway Management, or 25 Pa. Code Chapter 106, Floodplain Management, require a PennDOT highway occupancy permit, or require any other permit under applicable state or federal regulations, the permit(s) shall be part of the stormwater management site plan.
A. 
Any developer proposing to engage in a regulated activity shall submit four copies of the stormwater management site plan to the municipality or its designee.
B. 
Distribution of the stormwater management site plan will be as follows:
(1) 
Two copies to the municipality accompanied by the requisite municipal review fee, as specified in this Part 1.
(2) 
One copy to the Municipal Engineer.
(3) 
One copy to the Berks County Planning Commission.
A. 
The municipality or its designee shall review the stormwater management site plan for consistency with the adopted Act 167 Plan. The municipality or its designee shall require receipt of a complete plan, as specified in this Part 1.
B. 
In the case of a subdivision or land development, the Municipal Engineer shall review the stormwater management site plan for conformance with Chapter 425, Subdivision and Land Development, of the Code of Caernarvon Township, for all provisions not superseded by this Part 1.
C. 
For regulated activities requiring a PADEP joint permit application, the municipality or its designee shall notify PADEP whether the stormwater management site plan is consistent with the Act 167 Plan and forward a copy of the review letter to the municipality and the developer. PADEP may consider the municipality or its designee's review comments in determining whether to issue a permit.
D. 
The developer shall be responsible for completing an as-built survey of all stormwater management facilities included in the approved stormwater management site plan. The as-built survey and an explanation of any discrepancies with the design plans shall be submitted to the municipality or its designee for final approval. In no case shall the municipality or its designee approve the as-built survey until the municipality or its designee receives a copy of an approved declaration of adequacy/highway occupancy permit from the PennDOT District Office, and any applicable permits from PADEP.
E. 
The municipality or its designee's approval of a stormwater management site plan shall be valid for a period not to exceed one year unless a schedule is submitted and approved for a longer period of time as part of the approval process. This one-year time period shall commence on the date that the municipality or its designee approves the stormwater management site plan. If stormwater management facilities included in this approved stormwater management site plan have not been constructed, or if an as-built survey of these facilities has not been approved within this one-year time period, then the municipality or its designee may consider the stormwater management site plan disapproved and may recommend that the municipality revoke any and all permits. Stormwater management site plans that are considered disapproved by the municipality or its designee shall be resubmitted in accordance with § 410-18 of this Part 1.
A. 
Certain modifications to a stormwater management site plan after submission but before approval shall require a resubmission of the modified stormwater management site plan consistent with § 410-18 of this Part 1 and be subject to review as specified in § 410-19 of this Part 1. The modifications which would require a resubmission includes, but is not limited to, the following:
(1) 
A change in stormwater management facilities or techniques.
(2) 
The relocation or redesign of stormwater management facilities.
(3) 
Modifications that are necessary because soil or other conditions are not as stated on the stormwater management site plan (as determined by the municipality or its designee or the Municipal Engineer).
B. 
Any modification to a stormwater management site plan after approval shall be submitted to the municipality or its designee, accompanied by the applicable review fee.
