§ 60-40. Stormwater management plan.

No building, grading, or sediment control permit shall be issued until a satisfactory stormwater management plan (or a waiver thereof) shall have undergone a review and been approved by the city after determining that the plan or waiver is consistent with the requirements of this chapter. After review of the stormwater management plan, and modifications to that plan as deemed necessary by city, a stormwater management final plan must be submitted to the city for approval. The stormwater management plan shall at a minimum include the following:

(a)

Contact information. The name, address, and telephone number of all persons having a legal interest in the property and the tax reference number and parcel number of the property or properties affected.

(b)

Topographic base map. One inch equals 200 feet topographic base map of the site which extends a minimum of 100 feet beyond the limits of the proposed development and indicates existing surface water drainage including streams, ponds, culverts, ditches, and wetlands; current land use including all existing structures; locations of utilities, roads, and easements; and significant natural and manmade features not otherwise shown.

(c)

Calculations. Hydrologic and hydraulic design calculations for the pre-development and post-development conditions for the design storms.

(d)

Soils information. If a stormwater BMP depends on the hydrologic properties of soils (e.g., infiltration basins), then a soils report shall be submitted. The soils report shall be based on on-site boring logs or soil pit profiles. The number and location of required soil borings or soil sites shall be determined based on what is needed to determine the suitability and distribution of soil types present at the location of the BMP.

(e)

Maintenance and repair plan. The design and planning of all stormwater management facilities shall include detailed maintenance and repair procedures to ensure their continued function. These plans will identify the parts or components of a stormwater BMP that need to be maintained and the equipment and skills or training necessary. Provisions for the periodic review and evaluation of the effectiveness of the maintenance program and the need for revisions or additional maintenance procedures shall be included in the plan.

(f)

Landscaping plan. The applicant must present a detailed plan for management of vegetation at the site after construction is finished, including who will be responsible for the maintenance of vegetation at the site and what practices will be employed to ensure that adequate vegetative cover is preserved.

(g)

Stormwater best management practices operations and maintenance agreement. Proof of a recorded stormwater best management practices operations and maintenance agreement binding on all subsequent owners of land served by stormwater BMPs to ensure maintenance and repair in accordance with the specifications of this chapter.
