§ 18.12.1907. Additional Standards for Disturbed Drainage Ways.

(a)

Native and drought-tolerant or riparian vegetation, whichever is deemed most appropriate, shall be used in the disturbed drainageway.

(b)

In the event that a drainageway is disturbed during development activity, (e.g. stripping of natural vegetation), the developer will be required to:

(1)

Perform analysis of soils including pH texture, depth, type, and compaction;

(2)

Identify the direction of exposure (i.e. southern) of all surfaces and slopes of the drainage way;

(3)

Prepare discussion of the characteristic behavior of water and moisture in the drainage way;

(4)

Except for drainage ways designated to be "landscaped", prepare listing of diversified plant communities, with an emphasis on shrubs and forbs and consideration of wildlife needs, proposed for planting in the drainage way and the methods for irrigation;

(5)

Submit above with any other information explaining process by which the drainage way will be enhanced or the natural condition reestablished for review and approval by planning staff;

(6)

If the rehabilitation or modification is deemed acceptable, the owner/developer shall deposit a bond or letter of credit in the amount determined by the city to assure that plantings within the natural drainage way will be permanently established. The security shall remain in effect until the city determines that plantings have been permanently established, or for a period of not more than four years; and

(7)

In the event the city determines that rehabilitation and plantings have not been permanently established within the four-year period following construction, the city will determine the cost to replace and permanently establish such plantings. Such costs shall be deducted from the security and retained by the city for rehabilitating the drainage way. Any remaining security will be returned to the owner/developer.
