3. Purpose & Intent of Land Development Ordinance
Encourage proper planning to:
Maintain existing slope stability, and not increase potential for slope failure
Preserve at least existing capacities of watercourses and streams, and not increase the potential for flooding
Shall not accelerated water runoff, erosion, and sediment pollution that would affect adjoining properties or water resources
Control of such effects for promoting and maintaining the health, safety, and general well-being of the inhabitants
May require more than one slide

4. When is a Land Development Permit Required?
Developments in Zone of Moderate to Severe Slip Prone Soils
Exceptions:
Additions ≤ 100% of floor area of an existing single-family dwelling or accessory structure
Individual cemetery graves
Excavations for wells
Exploratory borings or excavations under direction of Professional Geologist or Engineer
Development to Affect Stream Channel
What is a stream?
“’Stream’ means a system including permanent or seasonally flowing water, a defined channel, floodplain, and riparian ecosystem. Streams have no defined size range, but are considered smaller than rivers.”
Developments Disturbing ≥ 1 Acre

9. Plan Content – Developments ≥ 1 Acre
All requirements of most recent OEPA Construction General Permit
“So that receiving stream’s physical, chemical, and biological characteristics are protected, and stream functions are maintained, post-construction storm water practices shall provide long-term management of runoff quality and quantity.”
May require more than one slide

10. Plan Content – Developments ≥ 1 Acre
All requirements of most recent OEPA Construction General Permit
Operators are required to file an NOI with Ohio EPA to obtain stormwater permit coverage under the Ohio EPA Construction General Permit OHC000005
A Stormwater Polluton Prevention Plan (SWP3) shall be developed which includes standard erosion and sediment controls as well as good housekeeping measures
Erosion, sediment, and stormwater management practices included in the SWP3 should meet the standards of the most current Ohio ‘s Rainwater and Land Development Manual
SWP3 shall include a description of the post-construction BMP to be installed to manage post-construction runoff that exceeds pre-construction runoff volumes
“So that receiving stream’s physical, chemical, and biological characteristics are protected, and stream functions are maintained, post-construction storm water practices shall provide long- term management of runoff quality and quantity.”
May require more than one slide

11. The Plan
The first step in developing your plan is to evaluate your construction site. What earth are you going to move and how do I work within what I have learned? Evaluate the hydrologic and other natural features of your site to better plan the required BMP’s.
Consider stockpiling dirt and how to
secure the stockpile, what BMP’s will
be required and what will I need to
order for the job.
Plan the work and determine a sequence to be followed and when the BMP’s shall be installed.

12. Intent of the SWP3
Develop a plan that includes effective erosion and sediment controls to minimize discharge of pollutants
Plan development in phases to minimize areas of disturbance to prevent erosion
Implement practices to control stormwater discharge volume and velocity
Layout development in a fashion to maintain a 50-foot undisturbed buffer around surface waters of the state and if possible avoid disturbance of steep slopes
May require more than one slide

13. Common SWP3 Implementation Issues
Failure to install perimeter sediment controls within 7 days of grubbing
Improper installation and maintenance of sediment controls
Failure to install and maintain an adequate construction entrance
Failure to temporarily stabilize disturbed areas idle for > 14 days
Poor housekeeping and management of non-stormwater pollutants (i.e.- concrete washouts, trash disposal, etc.)
Failure of Operator to conduct and record weekly and post-rainfall inspections
May require more than one slide

14. BMP’s or Best Management Practices

15. Construction Entrance
A rock construction entrance should be installed wherever it is anticipated that construction traffic will exit the project site onto any roadway, public or private. Access to the site should be limited to the stabilized construction entrance.

16. Perimeter Sediment Controls
Compost Filter Socks
Straw Wattles (i.e.-Fiber Rolls)
Silt Fence
Super Silt Fence

17. Compost Filter Socks or Straw Wattles
Compost Filter Socks or Straw Wattles consist of a biodegradable or photodegradable mesh tube filled, typically using a pneumatic blower, with a coarse compost filter media or straw that meets performance criteria.

18. Filter Fabric or Silt Fence

19. Super Silt Fence
Installed in steeper grade areas and to protect critical areas.

20. Filter Fabric or Silt Fence
Proper installation is critical. Experience from ODNR and other
field testing has shown that nearly 75 percent of silt fence does
not function properly due to poor installation. Proper installation consists of it being installed:
on the contour;
with sufficient geotextile material buried;
with the fence pulled taut and supported on the downstream side by strong posts:
and with the fence backfilled and compacted.

21. Filter Fabric or Silt Fence – Poor Installation

22. Inlet Protection
Inlet protection must be used in any inlet that drains to a storm sewer or outfalls to a watercourse.

23. Concentrated Flow Sediment Controls
Rock Filter Outlets
Rock Check Dams
Filter Fabric Check Dam
Filter Sock or Straw Wattle Check Dam

24. Rock Filters or Rock Checks
Rock filters or rock checks may be used to control runoff within constructed channels at the downstream end of the channel, during construction until the protective lining is installed or during a temporary disturbance within the channel.

25. Erosion Controls Preserve native vegetation Mulching and Seeding
Rolled Erosion Control Products
Rock Lined Channels and Outlets

26. Stabilization
However, the area will not be considered stabilized until a minimum uniform 70% vegetative cover of erosion resistant perennial species has been achieved. Critical areas — erodible soils, within 50 feet of a surface water, etc. — should be blanketed. Temporary sediment control BMPs that were installed for the earthmoving phase of the project must remain in place and be maintained in working order until permanent stabilization is achieved.

27. Post-Construction BMP Inspection and O&M
Long-term maintenance plan, in accordance with OEPA Construction General Permit, must be developed and provided to the post-construction Site Operator
At the end of a project, the City will meet with the Respective Parties to review Post- Construction BMPs and the O&M Plan for said BMPs
Site Operator must complete inspections (at least annually) per the long-term maintenance plan, and submit letter of certification each December to the City Engineer that inspections were completed in accordance with the long term maintenance plan

The amount of the bond shall be determined by the City Engineer.”

29. Inspection Fees
“ If it is determined that the City requires engineering services to evaluate, monitor, and/or enforce the terms of any plan, the City may require the developer to pay the entire cost of those engineering services. The City may obtain an estimate of the cost of said engineering services, and may require the developer to provide a bond to cover the anticipated cost of such engineering services.” { (b)}
City has contracted with Follow the River to perform these services
Inspection Fees will be collected when Land Development Permit is issued, and will be held in escrow to pay invoices for inspection services.
Inspection Fees will be based on estimated number of inspections, size of project, etc.
Excess funds will be returned to Permitee at the time of final completion
If funds for inspections run low, developer shall be required to submit additional funds for inspection services
