Attachment 06To: Planning Commission From: Lee Quintana Re: Agenda item No 4. 1 /11 /17 S-16-44 CONFLICTS/QUESTION House Size/ Compatibility Grading Landscaping Tree Impacts Consistency with HDS&G B. House Size and Neighborhood Compatibility (Page 4 Staff Report) • FAR does not apply in hillsides • This type of comparison is applicable to standard subdivisions, not hillside lots which vary greatly in respect to site conditions • Chart does not include square footage of the cellar at 15580 Gum Tree Land (application) • If look at the three most like sized parcels the totals of the three (including house, cellar and garage the proposed application is the largest. The totals are as follows: 15715 Gum Tree Lane 15675 Gum Tree Lane 15580 Gum Tree Lane 5217sgft 7415 sq ft 8895 sq ft (Application) C Grading and Fill Restoration (Page 5 Staff Report) • Fill exceeds maximum standard in area of road restoration in area of pool, patio and turf. (areas that are up to 60+ feet from the house. • It is not clear what areas actually exceed the maximum fill depth. • If these areas were brought closer to the house would it be possible to remain within the maximum fill depth as well as create a more natural restoration of the topography in the area? Part of rational for the increased fill is to utilize cut from the basement and reduce the required offhaul (2,145 cy cut, 1,235 cy fill, total earth movement 3,380 cy , 910cy offhaul (F. Geotechnical Review page 6 Staff Report) • The previous proposal did not include a cellar. It did not require as much cut or fill or offhaul. C. Landscaping (Page 5 Staff Report) • The Staff Report under E. Tree Impacts (page 5) states that most of the proposed landscaping is within 30 feet of the proposed residence and can be ornamental species of the applicant's choice. • Most of the landscaping on the front and sides of the residence is within 30 feet.. However, in the rear of the house the patio, pool and turf extend up to 60 feet +l- from the rear of the residence. • While ornamental and turf areas are allowed within 30 feet of the residence, the majority of the planting within 30 feet is required to be native species. (HDS&G) - As shown on the Landscaping Plan L.3.0 the turf area and pool are located more than 30 feet from the residence. • It appears that there is an extensive area of hardscape and ornimental landscaping even not considering the driveway/turnaround area E. Tree Impacts: • The Staff Report (page 5) states that 12 protected trees have been removed with a permit and that the removed trees will need to be replaced. • Four additional trees have been identified for removal with this application. • The arborist report Ex. 7 includes recommended conditions for replacement of three of the additional trees in addition to other conditions regarding revisions to the plans to avoid impact to other trees. It does not include conditions for the replacement of the origninal 12 trees that were removed. What provisions are being made for replacement of these 12 trees?

ISA Tree Risk Assessment Qualified / ISA Certified Arbarlst #NC-3172 3.0 Tree Location & Protection Fence Map The CIA marked up the applicant's preliminary grading and drainage plan sheet dated June 2016 by Hanna - Brunetti. The red dashed lines indicate the CTA's suggested chain link root protection fence alignment (initial rough). Based on the current proposed plan, most of the trees proposed to be retained and protected should have enough root zone square footage retained inside these fenced areas to maintain normal vigor (assuming that the general contractor erects fencing along the routes suggested on the map markup at right). Trees that may be negatively impacted include: • Trees #1, 4, 6, #7, and #8 due to proposed graded fill placement. • Tree #11 due to the proposed drain outfail. • Tree #14 due to encroachment by the proposed work footprint. • Tree #19, 25, and #30 due to proposed new driveway footprint development. • Tree #29 due to proposed water service line trenching. • Tree #30 which will be surrounded by various site plan elements on most sides of the tree. Yellow lines indicate the project team's proposed new drainage pipe trench route and the proposed new water service line trench route. 4.0 Observations & Discussion (See report section 1.0 Summary above for observation and discussion Items). t11 Site Address: t WO Gum Tres Lens, Los Gatos, CA Registered Member.
