SUBJECT: Combined Review for Marsoner Residence - 6199 N. 44th Street (APN: 169-20-115). Application for landscape and site drainage improvements.
Request
The owners of the property located at 6199 N 44th Street submitted an application for site drainage improvement and landscaping.
History/Background
The Town received a complaint regarding grading and landscape improvements on the subject property. The owner hired a landscape company to addresses existing erosion issues; however, the contractor did not receive Town approval for the modifications. Staff met with the owner and the neighbor to discuss the changes made to the site. The owner was informed that the modified area would have to be restored back to its natural state or submit an application for site and grading improvements. The applicant retained an engineer and submitted application for landscape and grading improvements.
Drainage Improvements
The new grading design will utilize some of the existing rip-rap, restores two parts of the disturbed area back to a natural state, and provides some on-site retention. Rock outlet structures will be used as energy dissipaters and for erosion protection. The rip-rap that will remain will be set in a colored concrete to help it blend in with the hillside. The concrete color is dark beige and has a light reflective value of approximately 20%. According to the drainage report, the improvements will reduce the drainage impact to the neighboring lots and will not result in changes to the existing and historic drainage patterns.
Landscape Improvements
Two areas of the disturbance will be restored back to natural grade and with native vegetation. The landscape/re-vegetation pallet consists of hop bush, creosote, golden eye, and barrel cactus.
