square foot swimming pool and spa in the rear yard. The proposed pool and deck are in
compliance with the setback and development area requirements established in Title 10, Zoning
and Site Development of the LAHMC.
The applicant is using the Council approved solar incentive to achieve the square footage to
build the swimming pool on the property. Per Section 10-1.502 b.6 of the LAHMC, the 500
square feet of solar panels will need to be installed on the roof of the residence prior to final
inspection of the swimming pool (condition of approval #5). The ordinance does not restrict
CDP lots from utilizing the development area bonus.
Outdoor Lighting
No landscape lighting is proposed at this time except for lights located within the proposed pool.
Trees & Landscaping
One (1) pine tree is proposed to be removed with this application.
Drainage
Water runoff generated from the new development will be collected and routed into a detention
vessel along the North East corner of the property. The vessel is. 18long with one (1) 2'6"
diameter perforated pipe and percolates into the ground.
Pursuant to Section 10-2.503, Drainage Facilities Standards, of the Municipal Code, the
Engineering Department has reviewed and determined that the proposed drainage design
complies with Town requirements. The Engineering Department will review and approve the
final drainage plan prior to acceptance of plans for building plan check. Final "as -built" grading
and drainage will be inspected by the Engineering Department, and any deficiencies will be
required to be corrected prior to final inspection.
