(A) A preliminary stormwater management plan must be submitted at the same time as any application submitted pursuant to Title 18 (Unified Development Ordinance) for the following: preliminary site development plan, Section 18.40.110, or preliminary plat, Section 18.40.150. The preliminary stormwater management plan must include conceptual stormwater management plans, sufficient information to evaluate the existing hydrologic and environmental characteristics of the development, impacts of the proposed development, preliminary sizing for detention facilities and stormwater treatment facilities, and locations of any existing or proposed stream corridors, floodplains, access easements, conservation easements, or tracts, and a description of the maintenance responsibility for proposed private detention facilities and stormwater treatment facilities. The City Engineer may set additional minimum submittal requirements.

(B) Following the receipt of the preliminary stormwater management plan, a general review meeting will be conducted with the City Engineer, City Planner, representatives of the developer and the developer’s engineer. The purpose of this meeting is to discuss the conceptual methods proposed to be utilized and the possible effects of the proposed development on existing or future adjacent developments. The receipt of the preliminary stormwater management plan and the occurrence of the meeting is a prerequisite to submission of a final stormwater management plan but does not obligate the City to issue any permits or approvals. The City Engineer has the discretion to waive the requirement of submitting a preliminary stormwater management plan prior to submission of a final stormwater management plan.
