A. 
For any proposed development a phased stormwater management plan shall be submitted to the Town for review and approval. Unless otherwise determined by the Town, plans shall be submitted for the concept, site design, and final stormwater management construction. When deemed appropriate by the Town due to minor cumulative impacts of the development and when the applicant has demonstrated that ESD standards have been met to the MEP, the site design and final stormwater management construction phases may be combined. Site plans, subdivisions, and building permits with a total proposed lot coverage of 15% and total land disturbance less than 20,000 square feet may combine all review phases when the applicant has demonstrated that ESD standards have been met to the MEP using the standard plan. Sites plans and building permits that meet the criteria outlined on the Kent County Standard Stormwater Plan may utilize the standard stormwater management plan.
B. 
Conceptual stormwater management plans should be submitted with conceptual/sketch site or subdivision plans and shall include sufficient information for an initial assessment of the proposed project and proposed stormwater. The concept review process will review at a conceptual level the feasibility, design and environmental characteristics of the proposal with a goal to ensure that significant natural areas are protected and to determine if stormwater management can be provided according the stormwater management measures identified in Article V, § 146-13, of this chapter.
C. 
Following conceptual approval and where applicable in conjunction with the preliminary site or subdivision plan, the applicant shall submit a site development plan. The site development plan shall include detailed designs for stormwater management and erosion and sediment control. The site development plan process will review the plan to ensure that all options for implementing ESD have been exhausted and comments received during conceptual review have been incorporated into the site development plan.
D. 
Following site development plan approval and where applicable in conjunction with the final site or subdivision plan and the sediment and erosion control plan, the applicant shall submit a final stormwater management plan. The final stormwater management plan shall include stormwater construction drawings accompanied by a report that includes sufficient information to evaluate the effectiveness of the proposed runoff control design. The final stormwater management plan process will review the plan and supporting documents for compliance with all applicable regulations and ensure that, when structural practices are used, all reasonable options for implementing ESD have been exhausted.[1]

E. 
The Town shall perform a comprehensive review of the stormwater management plans for each phase of the site design. Coordinated comments will be provided for each plan phase that reflects input from all appropriate agencies, including but not limited to the Kent Soil and Water Conservation District, the Galena Planning Commission and Galena Utilities. All comments shall be addressed and reflected in the next phase of project design.
F. 
The stormwater management plan shall not be considered approved without the inclusion of the signature and date of the signature of the Town of Galena designee for approval of stormwater management plans.

When the stormwater management plan involves direction of some or all runoff off the site, it is the responsibility of the applicant to obtain from the adjacent property owners any easements or other necessary property interests concerning flowage of water. Approval of a stormwater management plan does not create or affect any right to direct runoff onto adjacent property without the property owner's permission.
