§ 5. Drainage and inundation.

[a]

A drainage plan shall be made for each subdivision by the owner's engineer, which plan shall take into consideration the ultimate or saturated development of the tributary area in which the proposed subdivision is located. On-site storm water detention measures may be required by the planning commission. An erosion and sedimentation plan may be required as stipulated in Appendix B of these regulations.

[b]

The storm and sanitary sewer plans shall be worked out prior to the development of the other utility plans. Engineering considerations shall give preferential treatment to these gravity flow improvements, as opposed to other utilities and improvements. Off-premise drainage easements and improvements may be required to handle the runoff of subdivisions into a natural drainage channel. But under no condition shall storage drainage be emptied into the sanitary sewer system—or vice versa.

[c]

The planning commission may require whatever additional engineering information it deems necessary to make a decision on subdivisions and other development which contains an area of questionable drainage. Lakes, ponds and similar areas will be accepted for maintenance only if sufficient land is dedicated as a public recreation area, or if such area constitutes a necessary part of the drainage control system.

[d]

The City of Hoover will not allow development of one site to cause an adverse effect on adjacent property. In some cases, storm water retention or improvement of existing downstream drainage facilities may be required. The applicant is urged to contact the city engineer for a preliminary discussion on this matter prior to plan submittal. The minimum design standards for detention facilities are found in Article IX. (Ord. No. 89-857, § 1, 1-3-90)

[e]

All development in the City of Hoover shall be in compliance with Ordinance 311, the Hoover flood plain ordinance. The applicant is urged to contact the Hoover building official or city engineer for a preliminary discussion on this matter prior to plan submittal.

The City of Hoover will not allow a diversion of watershed from one drainage basin to another for any subdivision or development of land within its city limits.

(Ord. No. 88-771, § 3, 1-16-89)
