Storm Water Pollution Prevention (SWP3) Plan Review

 

All development that occurs in the unincorporated areas of Lake, Middleton, Perrysburg, and Troy Townships that disturbs 1/2 (one-half) or more acres of soil as a single development, or common plan of development must undergo SWP3 review and approval by the Wood County Engineer's Office. This applies to commercial, industrial, residential, non-agricultural development. SWP3 approval must take place before Lake, Middleton, Perrysburg, and Troy Townshipscan issue their respective zoning permits.

 

 

The plans must be submitted to the Wood County Engineer's Office with a completed SWP3 Application form. We will then review the plans, and issue approval. For single-lot, residential construction in a platted subdivision, the developer must submit a copy of the plot plan for the house, in addition to the completed SWP3 form. Single-lot residential construction does not have to submit a full SWP3 as this development will be governed by the overall SWP3 on file for the subdivision.

 

Effective January 2, 2017, the Wood County Engineer will require that all SWP3 submittals use the TMACOG SWP3 Submittal Coversheet which is linked below:

Storm Water Pollution Plan (SWP3) Inspection

 

Once approval has been granted, the townships may issue any zoning permits they require. After this, the site will be inspected by the Wood County Engineer's Office on a monthly basis, continuing until the site has been permanently seeded, and graded.

 

Some common problems during inspection include:

 

  • Improper, or absence of proper inlet (curb inlet or rear yard catch basin) protection

  •  

  • Improperly maintained silt fencing, or an overall absence of silt fencing

  •  

  • Improper construction entrances (must be stone, or aggregate, 2 inches in diameter to a depth of at least 6 inches, overtop a base of geotextile fabric)

  •  

  • If portions of the site are to remain undisturbed for more than 14 days, they must be temporarily seeded, or stabilized

  •  

  • Soil stockpiles that remain unstabilized, or unprotected for longer than 14 days

  •  

After each inspection, the Wood County Engineer will file a report. If there are problems with the site a letter will be sent to the operator asking that these problems be addressed. If they remained undressed, actions can be taken by the Wood County Engineer's Office to force compliance.

 

 

Post-Construction

 

All sites that must undergo SWP3 review must also submit maintenance plans that will be in effect after construction has been completed. For single-lot residential, the post-construction maintenance plan for the subdivision is sufficient.

 

Per the Wood County Subdivision and Site Improvement Manual, all new, residential subdivisions must be placed under the Wood County Engineer's Ditch Maintenance Program. See the Subdivision and Site Improvement Manual for more details.

 

Additionally, all post-construction best management practices must be designed to the standards outlined in Rainwater & Land Development, which is the state of Ohio's standard manual for post-construction storm water.
