Title
Stanton Weirsdale Drainage Retention Area - Waiver Request to a Major Site Plan
Project #2025070039 #33066 Parcel #49794-000-00
NV5, Inc.
LDC 6.13.3(C)(5) Types of stormwater management facilities
CODE states A retention/detention area that is adjacent to a public right-of-way shall be constructed to be aesthetically pleasing with curvilinear form and shall be landscaped with a mixed plant pallet meeting Marion-friendly landscaping standards minimally consisting of four shade trees and 200 square feet of landscaping comprised of shrubs and/or groundcover for every 100 lineal feet of frontage or fractional part thereof, or, in the case of a wet facility, a littoral zone meeting the governing water management district criteria. The proposed landscaping shall be arranged to provide ease of maintenance and screening of stormwater structures.
APPLICANT request due to the size of the site and the size of the required drainage retention area, it will be difficult to provide the required landscaping. This DRA is being constructed within an existing neighborhood as a retrofit to reduce existing flooding issues and space utilitized for landscaping will reduce the area/volume available for the DRA. Existing utility access will also make establishment and maintenance very difficult.
LDC 6.13.3(C)(1) Types of stormwater management facilities
CODE states retention/detention areas shall have side slopes no steeper than 4:1 (horizontal: vertical) with a minimum berm width of 12 feet stabilized at six percent grade maximum around the entire perimeter of the facility. Side slopes steeper than 4:1 may be allowed with additional accommodations related to public safety, maintenance, and access upon approval by the County Engineer or his designee.
APPLICANT requests that due to the size of the required DRA the maintenance path around the DRA needs to be reduced to 10 feet from 12 feet. This is a residential location.
