Engineering Design and Forms

The City of Bardstown has amended its Drainage Control Ordinance to meet the requirements of its Kentucky Pollutant Discharge Elimination System (KPDES)stormwater permit with the state of Kentucky.  This permit is called “Permit to Discharge from a Small Municipal Separate Storm Sewer System into Waters of the Commonwealth (MS4),” otherwise referred to as the KYG200000.  The new Drainage Control Ordinance not only addresses water quantity for new and redeveloped sites but also water quality.  Good water quality of the runoff from developed sites is very important to health of our streams. For a copy of our latest Drainage Control Ordinance see the link below.

Design
Bardstown has adopted guidance documents that include checklists and a Technical Stormwater Management Manual to aid in the design and plan submission process.  

Checklists to be submitted with design plans for approval:

Subdivision Plan Review Checklist (pdf)

Site Plan Review Checklist (pdf)

SWPPP Checklist 2011 (pdf)

Detention Pond Checklist (pdf)

How to Build a Raingarden (pdf)

 

The Technical Stormwater Management Manual was adopted from the State of Georgia, Volume 2 Technical Handbook, first edition, August 2001, Chapters 1 thru 3 and Appendix C & E. This Stormwater manual will aid in the design of stormwater quantity and quality controls. For information to aid in the design of stormwater drainage systems, pipes, ditches, etc. follow the Kentucky Transportation Cabinet’s Drainage Manual.

Need help putting together a Stormwater Pollution Prevention Plan (SWPPP) for your project?  Visit the Environmental Prevention Agency’s (EPA) website listed below and get information on how to develop your SWPPP plan, templates to follow, sample inspection forms to use, example plans and other helpful information.

Maintenance of Stormwater Management Facilities is vital to their function and the City’s goal of have clean and safe streams in our community.  All new and redevelopment sites with stormwater facilities whether for quality or quantity are required to sign and record in the Nelson County Clerk’s office a Stormwater Management Facilities Maintenance Agreement and submit to the City Civil Engineer Prior to applying for a Land Disturbance Permit.  Click below for a sample agreement with the minimum requirements by Odinance.

Best Management Practices for Landscaping Operations
You can help keep our waterways clean by following these Best Management Practices for landscaping operations.

  1. Your responsibility to the environment starts as soon as you pick up your materials. Avoid overloading trucks with mulch that will spill out onto the road. Not only does this waste your materials, but mulch on the road ends up in the nearest storm drain, reaching our waterways.

  2. Grass and leaves should never be blown into the street or into storm drains.

  3. Use a mulching mower and leave grass clippings on the lawn.

  4. Compost leaves, sticks, or other collected vegetation or dispose of it at a permitted landfill. Do not dispose of collected vegetation into storm sewers or waterways.

  5. Place collected material away from storm drain inlets and waterways. Any material left out overnight or during rain should be covered.

  6. Apply fertilizers, pesticides and other chemicals in moderation.

  7. Do not apply fertilizers or pesticides if rain is predicted over the next day. They will not remain on the lawn and will wash into the nearest storm drain or creek.

  8. Sweep sidewalks, driveways and streets if fertilizer is spilled on these surfaces.

  9. Train employees to follow these Best Management Practices. Install BMP signs in vehicles as reminders.

  10. Blowing or raking yard waste into storm drains, creeks and waterways is prohibited by law. Violators will be subject to penalties including Notices of Violation, Civil Citations, and fines.

  11. Grass, leaves, mulch and other yard waste may seem harmless, but these materials can have a devastating effect on creeks and streams. When yard waste ends up in our waterways, it decays and depletes oxygen, suffocating fish and other aquatic life. Nutrients from yard waste also promote excess algae growth, further polluting streams and ponds.
