To: Mayor and City Council Members
Chairperson and Planning Commissioners
From: Gary Chao, Assistant Director of Community Development %
Prepared by: Erick Serrano, Assistant Planner
Date: December 23, 2014
Subject: Director's Minor Modification, DIR-2014-39, to allow landscaping enhancements at a
residence located in the Seven Springs Planned Development District at 11570 Upland Way.
Chapter 19.164 of the Cupertino Municipal Code allows for administrative approval of
minor changes in a project. Chapter 19.12 of the Cupertino Municipal Code requires the
Director to report his/her decision to the City Council and Planning Commission in time

DISCUSSION
The applicant, Tien Wu, is requesting to make landscaping enhancements at an existing single-family
residence at 11570 Upland Way. The subject property is located within the Seven Springs Planned
Development District, and any significant exterior changes require approval by the Director of
Community Development. The applicant received approval from the Seven Springs Owners
Association for the project.
The proposed enhancements include:
• Total landscape area of 3,960 square feet. The turf area will measure 580 square feet, and the
non-turf plan area will measure 3,380 square feet. The project is subject to a landscape project
submittal at the building permit stage per the City's Landscape Ordinance since the modified
area is over 2,500 square feet.
• Eighty-four percent of the plantings are low water use plants according to the Water Use
Classification of Landscape Species (WUCOLS). The remaining sixteen (16) percent are
moderate water use.
• A new irrigation system that utilizes low-volume irrigation on eighty-five (85) percent of
planting areas, and high efficiency nozzles will be used to spray fifteen (15) percent of the
planting area (lawn). The overall design exceeds the average landscape water efficiency of
seventy(70) percent.
• The installation of an irrigation control system.
• Replacement of an existing rear concrete paver patio with a pervious, gold decomposed granite
patio.

PLANTING NOTES
-After the removal of all dead and unwanted plant material,organic compost will be added
while rototilling to a depth of eight inches.Plants and turf not to be removed are labeled
�existing on plant plan.The only tree to be removed is a small,unproductive stonefruit.
c
-All plant holes will be twice the diameter and one and a third the depth of the rootball of the
container plant to allow room for 4 parts native soil,one part organic compost around the root-
ball.
-A two year time release fertilizer(Agriform or Ozmocote)will be added in the bottom of the
hole at
appropriate amounts to each plant.
-Perlite will added around the rootballs of all succulent plants to increase drainage in their im-
mediate area.

Construction Notes:
1.After the removal of all dead or unwanted plant material.
a m e n d m e n t w i l l b e a d d e d w h i l e r o t o t i i l i n g t h e s o i i t o a
depth of 8"to improve drainage and soil fertility.Grade wili
be returned to existing grade through this process.
2.The total landscape area being converted in this project
(totai outdoor area minus the existing hardscape�is 3960
square feet.We wili be leaving 580 square feet of existing
turf in the front,the total turf area after
conversion.
3.Existing storm water management will not be changed
during this lan scape project.�S marks locations of the
downspouts,C�marks the locations of the curb outlets.
4,Irrigation water comes from Santa Clara Vailey Water
District,municipal water.Irrigation pian is on page 2 of this
packet.
5.Will schedule for lands�ape installation report with
Planners upon completion of landscape installation.
Irrigation Notes:
1.Check and test existing irrigatin system.Repair and/or
adjust portiions to remain.
2.The static water pressure from the municpal supply is 70
p.s.i.The station watering the lawn will have a flow rate of
3-5 g.p.m.,an application rate of.0.45 i.p.h.,and a design
operating pressure of 70 p.p.s.i.The six drip stations will
have flow rates between.25-5 g.p.m.,application rates
between.5-6 i.p.h.,and a design operating pressures of 25
p.p.s.i.
3.Separate hydrozones to each area of plantings is
unnecessary because there is a small difference in water
needs between in eac watering zone that can be accounted
for with different emmiters.Cupertino is in California climate
zone 4 according to the California Energy Commission.
4.The watering schedule will be three days a week,
between the hours of 5:00 am and 8:15 am.Each drip line
will run for twenty-five to thirty minutes and the lawn will run
fifteen to twenty minutes per day.This schedule will be
adjusted according to saturation points specific to site and
as plants establish.Succulents can be removed from drip
system once fully established.
5.Low-volume irrigation will be used on 85%of planting
areas and high effiency nozzles will be used to spray 15%of
planting area(lawn).The lawn area is surrounded on three
sides by a border of groundcover to utilize any overspray
and runoff that may occur.There will be minimal runoff,head
drainage,or overspray through this landscape.The design
exceeds the average landscape water efficiency of 70%.
6.Continued irrigation maintenance to include routine
inspection to establish correct wotking order of parts and
adequate saturation points for different plantings as they
establish.
