City of Toledo


The Stormwater Coalition, administered by the Toledo Metropolitan Area Council of Governments (TMACOG), has issued the 2008 Stormwater Management Standards Manual, 3rd edition. The Stormwater Coalition is a group of environmental profes­sionals who help communities deal with stormwater problems and regulations. The coalition is comprised of staff members from local jurisdictions, agencies, and TMACOG’s Environmental Planning department. The coalition helps elected officials and administrators, build­ers and engineers.

The purpose of the Stormwater Management Standards Manual is to protect natural resources, manage stormwater with better site design and techniques and meet the water quality standards of the Clean Water Act. Responsible stormwater management prevents stream bank erosion and channel siltation, reduces flooding, and improves water quality. These standards are in compliance with the U.S. and Ohio Environmental Protection (EPA) stormwater rules, under the Phase II stormwater requirements for the waterways of the state and nation with modifications as appropriate for application in northwest Ohio.

Clean water resources, such as the Maumee River and Swan Creek, are essential to the Toledo region. Stormwater runoff has added significant pollution to these waters, which limits the use of the streams and harms the environment. To address runoff pollution, the U.S. EPA issues stormwater permits to jurisdictions. A list of jurisdictions required to have stormwater permits, known as Phase I or Phase II communities. In the TMACOG area, 34 political jurisdictions are subject to EPA Stormwater NPDES Permits.

STATE OF OHIO Storm Water Program

CHAPTER 3745-39 OF THE ADMINISTRATIVE CODE

3745-39-02 Objectives of the Ohio EPA storm water management program for small MS4s.

(A) Storm water runoff continues to harm Ohio's waters. Runoff from lands modified by human activities can harm surface water resources in several ways, including the changing of natural hydrologic patterns and elevating pollutant concentrations and loadings. Storm water runoff may contain or mobilize high levels of contaminants, such as sediment, suspended solids, nutrients, heavy metals, pathogens, toxins, oxygen-demanding substances and floatables.

(B) The purpose of the Ohio EPA storm water management program for small municipal separate storm sewer systems (MS4s) is to regulate sources to protect water quality and to establish a comprehensive storm water management program. In this program, small MS4s have flexibility to determine the best management practices and measurable goals that are most appropriate for their system, for each of the six minimum control measures described in paragraph (C) of rule 3745-39-03 of the Administrative Code.

(C) What constitutes a municipal separate storm sewer system is often misinterpreted and misunderstood. The term does not solely refer to municipally owned storm sewer systems, but rather is a term of art with a much broader application that can include, in addition to local jurisdictions, state and federal facilities, public universities, local sewer districts, public hospitals, federal installations, military bases and prisons. The municipal separate storm sewer system is not just a system of underground pipes – it can include roads with drainage systems, gutters and ditches.

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-39-01 of the Administrative Code.]

(2) Minimum control measures.

(e) Post-construction storm water management in new development and redevelopment.

  1. You must develop, implement and enforce a program to address storm water runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale, that discharge into your small MS4. Your program must ensure that controls are in place that would prevent or minimize water quality impacts.
  2. You must:
  1. Develop and implement strategies that include a combination of structural, non-structural, or both types of best management practices as you determine appropriate for your community;
  2. Use an ordinance or other regulatory mechanism to address post-construction runoff from new development and redevelopment projects to the extent allowable under state or local law; and
  3. Ensure adequate long-term operation and maintenance of best management practices.

(Ord. 607-07. Passed 10-2-07.)

CHAPTER 943: Storm Water Management Program

943.01 Purpose and objective.

  1. Chapter 943 establishes storm water rates and service charges. Monies collected from these charges are to be utilized solely for the management of storm water.
  2. The Division of Sewers and Drains, Department of Public Utilities shall promote the public health, welfare and safety and provide for the: (1) safe and efficient capture of storm water runoff; (2) mitigation of the damaging effects of storm water runoff; (3) addressing of storm water problems; (4) funding of the activities of storm water management; and (5) design, planning, regulation, education, coordination, construction, operations, maintenance, inspection and enforcement activities related to storm water.

(Ord. 586-99. Passed 11-9-99.)

"Equivalent Residential Unit (ERU)" is a value, equal to 2,500 square feet of measured impervious area and is equal to the average amount of impervious area of residential properties within the City of Toledo.

"Square footage of impervious area" means, for the purpose of assigning an appropriate number of ERUs to a parcel of real property, the square footage of all impervious area using the outside boundary dimensions of the impervious area to include the total enclosed square footage, without regard for topographic features of the enclosed surface.

943.03 Necessity for Charges.

It is hereby determined necessary for the protection of public health, safety, and welfare and to conform with Federal, State, and local laws and regulations that a system of charges for storm water service be established which allocates the cost of providing storm water service to each user in such a manner that the allocated costs are proportionate to the cost of providing storm water service to that user, insofar as those costs can reasonably be determined.

(Ord. 586-99. Passed 11-9-99.)

943.04 Powers of Director of Public Utilities.

Storm water service charges levied pursuant to this chapter shall be collected by the Department of Public Utilities. The Director of Public Utilities shall make and enforce such rules and regulations as deemed necessary for the safe, economical, and efficient management and protection of the City's storm water system; for the construction and use of storm sewers and connections to the storm water system consistent with policies established by the Toledo City Council; and for the regulation collection, rebating and refunding of such storm water charges. The Director of Public Utilities shall report to City Council and the citizens of Toledo, every six months, as to the financial status of the Storm Water

Fund. This report shall include all receipts, expenditures, projects completed and projects planned over the next reporting period.

(Ord. 586-99. Passed 11-9-99.)

943.05 Rate structure.

  1. A storm water service charge shall be billed to the owner of each and every lot and parcel of land within the City that contains impervious area and contributes directly or indirectly to the storm water system of the City. This charge is necessary to pay for the repair, replacement, planning, improvement, operation, regulation and maintenance of the existing and future City storm water system. This charge is not related to water and/or sewer service and applies whether or not the premises are occupied.
  2. All properties having impervious area within the City of Toledo will be assigned an Equivalent Residential Unit (ERU) or a multiple thereof, with all properties having any impervious area receiving at least one (1) ERU as follows:
    1. All residential properties, as defined in Section 943.02(w), will be assigned one (1) ERU. A flat rate will apply to all residential properties.
    2. All non-residential properties, as defined in Section 943.02(o), will be assigned an ERU multiple based upon the properties' individually measured impervious area (in square feet) divided by 2,500 square feet (1 ERU) but in no event less than one (1) ERU. This division will be calculated to the first decimal place and rounded according to mathematical convention.

(Ord. 586-99. Passed 11-9-99.)

  1. The storm water charge shall be $0.1248 per day per Equivalent Residential Unit (ERU) which amounts to an average of $3.80/month. Owners of property who are eligible for the Water Discount Program as specified in Toledo Municipal Code section 933.02 (a)(7) shall be charged $0.0936 per day per Equivalent Residential Unit (ERU) which amounts to an average of $2.85/month. [eff. from and after 11-1-09]

(Ord. 644-08. Passed 11-5-08.)

943.09 Adjustments.

  1. In the event the amount of impervious area on a non-residential property is increased above that assigned by the Department of Public Utilities, an adjustment may be made to the ERU multiple assigned to the property to properly reflect the amount of impervious area. The new ERU multiple shall be billed from the date on which the Department mails a notification of the change to the owner of the property and shall not be stayed by an appeal under Section 943.10. If the Department of Public Utilities finds that it has been underbilling a non-residential property as a result of the increase in impervious area, the owner may be charged for the difference between the amount actually billed and the amount that should have been billed for a period of time not to exceed one year prior to the date of the Department's mailing of a notification to the owner that an adjustment is being made to the property's ERU multiple.
  2. The owner of a non-residential property may apply for an adjustment to the ERU multiple if the owner has taken certain actions that reduce the impact of storm water runoff to the storm water system. The maximum adjustment that may be made to the ERU multiple for any non-residential property is 50% consisting of any one or more of the following credit options:

 

(1) brownfield reuse

10%

(2) detention/retention

30%

(3) direct discharge

10%

(4) forested (stream) buffer/grass filter strip
