(2) Based on the percent imperviousness, a "tier factor" shall be determined, based on the following categories: City of South Burlington Ordinance VD). l ?c 2cito ORDINANCE REGULATING THE USE OF PUBLIC AND PRIVATE 28 SANITARY SEWERAGE AND STORMWATER SYSTEMS IMPERVIOUS PERCENTAGE TIER FACTOR 1 to 10.99% * See Below 11 to 20.99% 0.15 21 to 30.99% 0.25 31 to 40.99% 0.35 41 to 50.99% 0.45 51 to 60.99% 0.55 61 to 70.99% 0.65 71 to 80.99% 0.75 81 to 90.99% 0.85 91 to 100% 0.95 *Fee will be based on actual amount of Impervious Surface, measured in square feet.The gross area of the parcel shall be multiplied by the tier factor, and then divided by the ERU. The resulting value is rounded up to the nearest whole number which is the number of ERUs for the property. (C) The ERUs allocated to properties comprised solely of City owned roadways shall be determined by dividing two-thirds of the total Impervious Surface for the property by the ERU. The resulting value is then rounded up to the nearest whole number which is the number of ERUs for the property. 6.4 Billing and Collection (A) Stormwater user fees will be billed quarterly and shall be reflected on the water and sewer bills for each property owner,where applicable. The bill shall also state the ERUs allocated to each property. (B) A property owner may appeal an allocation of ERUs to the Stormwater Superintendent by submitting a written notice of appeal to the Stormwater Superintendent within fifteen (15) calendar days of the mailing date of the bill. The Stormwater Superintendent shall promptly meet with the property owner and issue a decision of the allocation of ERUs. A property owner may appeal the Stormwater Superintendent's determination regarding Credit revocation in the same manner set forth in Section 6.2(B). The filing of an appeal shall not relieve a property owner of the obligation to pay the user fee when due. (C) In the event any stormwater user fee is not paid within thirty (30) days from the billing date, a late penalty charge will be added to the fee together with interest charges. The amount of the late penalty charge and the interest rate on the overdue accounts shall be the same as those applied to delinquent taxes.

City of South Burlington Ordinance VC)H. I ?c3U2 ORDINANCE REGULATING THE USE OF PUBLIC AND PRIVATE 34 SANITARY SEWERAGE AND STORMWATER SYSTEMS ARTICLE VIII - MUNICIPAL COST SHARING 8.1 Purpose The Purpose of this article is to establish a City policy regarding cost sharing of upgrading or improving Stormwater Treatment Practices that are required by the MS4 Permit, Flow Restoration Plans (FRPs), Phosphorus Control Plans(PCPs)or any other future MS4 permit requirement. 8.2 Applicability (A) This section shall apply to stormwater system upgrades or improvements as required by Article VII of this document. 8.3 Municipal Share of Stormwater Project Costs (A) The City shall share in the cost of upgrading or improving Stormwater Treatment Practices(STPs) that are required by the MS4 Permit, Flow Restoration Plans (FRPs),and/or Phosphorus Control Plans (PCPs)as follows: (1) The City shall contribute funds from the stormwater utility budget for the construction of upgrades or improvements to STPs on a pro rata basis. Cost sharing shall be determined by the percentage of impervious surface area that is publicly owned and covered by the existing stormwater permit as compared to the total impervious surface area covered by the existing stormwater permit; (a) Areas outside of the existing stormwater permit that drain to the STP will not be included in this calculation unless the additional off-site area is routed to the STP as part of the upgrade or improvement. If offsite areas are being redirected to the STP as part of the upgrade or improvement,then these areas will be included as part of the City's impervious surface area in the cost sharing calculation. (2) The City's share of funding for upgrades or improvement of any particular STP will be determined on a schedule established by and at the discretion of the City. The City will update this schedule on an annual basis, as needed,to ensure that expenditures are budgeted in a way that is sustainable for the stormwater utility sinking fund, stormwater utility rate payers and permit required objectives. (3) The City will cost share in the upgrade or improvement of an STP to the minimum design requirements that achieve the stormwater treatment necessary to satisfy FRPs, PCPs and Vermont Stormwater Management Manual (VSMM).Work included as part of any upgrade or improvement that is beyond the minimum necessary to meet the minimum design requirements will be the responsibility of the Owner of the Regulated Private System.The City will not share in the cost of any work undertaken that is not directly related to the STP. City of South Burlington Ordinance --1 ORDINANCE REGULATING THE USE OF PUBLIC AND PRIVATE 35 SANITARY SEWERAGE AND STORMWATER SYSTEMS (4) The City shall review and will share in the costs of any change orders during construction until the total of change order requests exceeds 10%of the estimated total project cost. Change order requests seeking cost increases beyond 10%of the estimated total project cost will be borne by the Owner of the Regulated Private System, unless otherwise agreed to by the City and is in the Stormwater Superintendent's sole and complete discretion. (5) The City shall not contribute funds for engineering or design services incurred as part of upgrades or improvements to STPs unless; (a) The City obtains grant or other outside funding for the engineering or design project and a signed stormwater system improvement agreement with the Owner of the Regulated Private System that addresses engineering or design cost sharing is in place; (b) The City will not be responsible for engineering or design costs that were incurred prior to the effective date of a stormwater system improvement agreement for the upgrade or improvement to the STP. (6) The City will provide its pro rata share of STP upgrade or improvement costs only after the Stormwater Superintendent or the Stormwater Superintendent's designee has inspected the stormwater treatment system and the STP upgrade or improvement and certified that it has been constructed in accordance with the previously approved project plans. (7) The City is not required to obtain grants or other outside funding for any individual project. Grants will be obtained at the discretion of the Stormwater Superintendent based on staff availability and other factors. (8) If a grant or outside funding is obtained by the City for a STP upgrade or improvement project, such grant or outside funding will first be applied to offset the City's pro rata share of the STP upgrade or improvement costs.Any amount in exceedance of the City's pro rata share may be applied to the Regulated Private System Owner's pro rata share of the STP upgrade or improvement project costs at the discretion of the Stormwater Superintendent. (9) STP upgrade or improvement projects that are eligible for City cost sharing must follow the process outlined for inclusion of the stormwater treatment system under the City's MS4 Permit as established in Sections VII of this document. (a) If a Regulated Private System Owner performs an upgrade or improvement to an STP, but does not intend to obtain coverage under the City's MS4 Permit and instead obtains permit coverage directly from the State of Vermont,they may still obtain cost sharing from the City pursuant the requirements of this Article. In order to be eligible,these projects must: (i) Submit engineering and design plans for STP upgrade or improvement to the Stormwater Superintendent and obtain written approval of these plans prior to incurring any costs that would be eligible for cost sharing; and (ii) Sign a stormwater system improvement agreement with the City that establishes pro rata cost sharing for all parties involved;and City of South Burlington Ordinance vol- i %c jy ORDINANCE REGULATING THE USE OF PUBLIC AND PRIVATE 36 SANITARY SEWERAGE AND STORMWATER SYSTEMS (iii) Obtain the Stormwater Superintendent's written confirmation that the STP upgrade or improvement was constructed in conformance with the approved plans once construction is complete.
