An overlay showing soil types and boundaries based on the Lehigh or Northampton County Soil Survey, as applicable, latest edition. Any hydric soils present on the site should be identified as such.
An adequate access easement around all stormwater BMPs that would provide municipal ingress to and egress from a public right-of-way.
Other control devices or methods such as roof-top storage, semipervious paving materials, grass swales, parking lot ponding, vegetated strips, detention or retention ponds, storm sewers, etc.
The BMP operations and management plan, as required in Article VII, describing how each permanent stormwater BMP will be operated and maintained and the identity of the person(s) responsible for operations and maintenance. A statement must be included, signed by the landowner, acknowledging that the stormwater BMPs are fixtures that cannot be altered or removed without approval by the municipality.
Significant environmental resources considered in the site design assessment include, but are not limited to, steep slopes, ponds, lakes, streams, wetlands, hydric soils, floodplains, riparian vegetation, native vegetation and special geologic features.

One copy to the municipal governing body.
Drainage plans involving more than 10,000 square feet of additional impervious cover shall be submitted by the developer (possibly through the municipality) to the Lehigh Valley Planning Commission as part of the preliminary plan submission. The Lehigh Valley Planning Commission will conduct an advisory review of the drainage plan for consistency with the Trout/Bertsch Creeks Watershed and Hokendauqua Creek Stormwater Management Plans. The LVPC will not review details of the erosion and sedimentation plan or the BMP operations and maintenance plan.
The LVPC will provide written comments to the developer and the municipality, within a time frame consistent with established procedures under the Municipalities Planning Code,[1] as to whether the drainage plan has been found to be consistent with the stormwater management plan.
For regulated activities specified in § 139-5B(3) and (4), the drainage plan shall be submitted by the developer to the municipal building permit officer as part of the building permit application.
For regulated activities specified in § 139-5B(5), (6) and (7):
The drainage plan shall be submitted by the developer to the Lehigh Valley Planning Commission for coordination with the DEP permit application process under Chapter 105 (Dam Safety and Waterway Management), Chapter 106 (Flood Plain Management)[2] of DEP's Rules and Regulations and the NPDES regulations.

The municipality shall review the drainage plan, including the BMP operations and maintenance plan, for consistency with the adopted Trout/Bertsch Creeks Watershed and Hokendauqua Creek Watershed stormwater management plans as embodied by this chapter and with any permits issued by DEP. The municipality shall also review the drainage plan against any additional storm drainage provisions contained in the municipal subdivision and land development or zoning ordinance,[1] as applicable.

The municipality may require an "as-built survey" of all stormwater BMPs and an explanation of any discrepancies with the drainage plan.
A modification to a submitted drainage plan for a proposed development site which involves a change in control methods or techniques, or which involves the relocation or redesign of control measures, or which is necessary because soil or other conditions are not as stated on the drainage plan (as determined by the municipality) shall require a resubmission of the modified drainage plan consistent with § 139-22 subject to review per § 139-23 of this chapter.
The municipality may hear requests for waivers where it is alleged that the provisions of this chapter inflict unnecessary hardship upon the applicant. The waiver request shall be in writing and accompanied by the requisite fee based upon a fee schedule adopted by the municipality. A copy of the waiver request shall be provided to each of the following: municipality, municipal engineer, municipal solicitor and Lehigh Valley Planning Commission. The request shall fully document the nature of the alleged hardship.
The municipality may grant a waiver provided that all of the following findings are made in a given case:
That because of such physical circumstances or conditions, there is no possibility that the property can be developed in strict conformity with the provisions of this chapter, including the "no harm" provisions, and that the authorization of a waiver is therefore necessary to enable the reasonable use of the property;
In granting any waiver, the municipality may attach such conditions and safeguards as it may deem necessary to implement the purposes of this chapter. If a hardship waiver is granted, the applicant must still manage the quantity, velocity, direction and quality of resulting storm runoff as is necessary to prevent injury to health, safety or other property.
For regulated activities described in § 139-5B(1) and (2), the Borough of Walnutport shall hear requests for and decide on hardship waiver requests on behalf of the municipality.
For regulated activities in § 139-5B(3), (4), (5), (6) and (7), the Zoning Hearing Board shall hear requests for and decide on hardship waiver requests on behalf of the municipality.
