- construction, or erection of any structure shall occur, except in accordance with a revised stormwater permit first being issued by the Town of Landis.
- • If multiple lots are being served by the BMP, identify the lots that are using the stormwater BMP for treatment of runoff.
- • Security in the form of a bond, letter of credit, sinking fund or cash deposit may be required.
- • The following statement: "Each Lot or Tract served by the Stormwater BMP is jointly or severally responsible for repairs and maintenance of the Stormwater BMP and any unpaid ad valorem taxes, public assessments for improvements and unsafe building and public nuisance abatement liens charged against the facility, including all interest charges together with attorney's fees, cost and expenses of collection. The failure to maintain Stormwater BMP is a violation of the UDO subjecting each lot owner subject to significant daily civil penalties and other enforcement actions as more specifically set forth in the Landis Code of Ordinances."

Exhibit B: B: An operation and maintenance plan or manual, together with a budget. This exhibit shall include:

- • The operation and maintenance plan or manual indicating what operation and maintenance actions are needed, and what specific quantitative criteria will be used to determine when those actions are to be undertaken. The plan or manual must indicate the steps that will be taken to restore a stormwater system to design specifications if a failure occurs. The recommended schedule of maintenance and corrective actions listed in the Stormwater Best Management Practices Manual published by North Carolina Division of Water Quality may be used for a base document if the information is customized to include BMP structure names and adjusted to match site conditions. This information can be found on the NCDENR website at https://deq.nc.gov/about/divisions/energy-mineral-and-land- resources/stormwater/stormwater-program/stormwater-rules-and-regulations
- • An estimated cost of construction for each BMP. This value should be based on the actual site conditions and include values for the various cost associated with the BMP construction such as the basin excavation, sediment removal, riser structure, barrel, underdrains, baffles, sand, turf reinforcement, sod, vegetation, outlet protection, etc.
- • A budget for annual costs including:

► Routine maintenance, periodic sediment removal and replenishment of riprap. Values published by the EPA may be used for the calculation of maintenance costs associated with BMP maintenance. The information with the documentation and formulas annual maintenance costs for BMP's can be found at: http://www.epa.gov/guide/stormwater/files/usw\_d.pdf. This publication equates the maintenance costs of a BMP as a percentage of the construction costs. Please note that the publication has formulas to generate the calculated construction costs for a BMP. fu order to use these formulas for maintenance values, the calculated construction costs rather than a construction bid cost must be used as the basis for the annual maintenance costs. The other option is to develop construction and maintenance values for review by the Town. If this option is used, please state the assumptions and source of construction and maintenance costs. ► Insurance premiums. This value shall be based on premiums for liability insurance in an amount of not less than one million dollars ($1,000,000.00) covering all occurrences commonly insured against
