DESCRIPTION
This Public Hearing item was continued from the November 14th City Council
Meeting. At that meeting, the Council established Sunday, November 27th, for
a field trip to the site, adjourned to a regular meeting for November 29th,
and reserved December 6 and 13, 1988 and January 10, 1989 for additional
Regular Meeting dates. Additionally, the Council indicated the meeting
discussions will follow the four major issues identified in the Summary on
pages 1 and 2 of the November 14th Hansen Hill Ranch Staff Report:
1. CONFLICT WITH OPEN SPACE POLICIES OF THE GENERAL PLAN
The General Plan Open Space policies are:
- 3.1A Preserve oak woodlands, riparian vegetation, and natural creeks
as open space for their natural resource value.
- 3.1B Maintain slopes predominately over 30 percent (disregarding
minor humps or hollows) as permanent open space for public
health and safety.
- 3.1C Continue requiring reservation of steep slopes and ridges as
open space as a condition of subdivision map approval.
The project proposes to fill the heavily wooded ravine and develop the
area with single family houses. Certain areas with slopes over 30 percent
would be graded to allow residential development.
Should the General Plan policies be changed to allow residential
development on areas that would otherwise be maintained as open space?

2. TYPE AND NUMBER OF DWELLING UNITS (LAND USE DESIGNATION AND DENSITY) FOR
THE DEVELOPABLE AREAS
The Applicant' s proposal, the Planning Commission' s recommendation and the
Staff' s recommendation regarding the type and number of dwelling units (the
Land Use Designation and Density) are substantially different:
Type of Applicant's Planning Commission Staff's
Dwelling Unit Proposal Recommendation Recommendation
Single Family (0.9-6.0 DU/Acre) (0.9-6.0 DU/Acre) (0.5-2.8 DU/Acre)
174 maximum 129 maximum
Patio (zero (0.9-6.0 DU/Acre) (0.9-6.0 DU/Acre) -0-
lot line) 37 maximum
Medium Density (6.1-8.0 DU/Acre) (6.1-8.0 DU/Acre) (6.1-8.0 DU/Acre)
(townhouses) 34 maximum 50 maximum
TOTAL 245 maximum 235 maximum 179 maximum
What is the appropriate type and number of dwelling units (Land Use Designation
and Density) for the developable areas?
3. SIGNIFICANT ENVIRONMENTAL IMPACTS ON OAK/BAY WOODLANDS AND STREAM
(RIPARIAN) CORRIDOR
The project as revised would result in the loss of over 600 major trees (trees
over 3 feet in circumference 2 feet above ground) primarily in the ravine area
and along Martin Canyon Creek. The project as revised would also disturb the
stream (riparian) corridor along Martin Canyon Creek.
Should the project avoid impacting the oak/bay woodlands and stream corridor,
or are these impacts acceptable based on specific overriding benefits?
4. SIGNIFICANT ENVIRONMENTAL IMPACTS FROM MASS GRADING
The project as revised would involve approximately 930,000 cubic yards of soil
to be moved and a 50 foot fill in the ravine.
The Applicant has indicated that a substantial amount of the "cut" on site
would enhance the views from existing houses along Hansen Drive. The project
would have balanced amounts of on-site cut and fill to eliminate off haul
impacts on residential streets.
Staff recommends that the ravine be maintained instead of filled and that the
mass grading be substantially reduced or eliminated through a combination of in
place recompaction and off haul using the proposed Valley Christian Center road
connecting to Dublin Boulevard.
Should the project avoid mass grading, or are the associated impacts acceptable
based on specific overriding benefits?
For a more detailed discussion of these issues refer to the November 14th Staff
Report, Attachments and General Plan.
Since the Public Hearing on the Hansen Hill Ranch project was continued from
the November 14th Meeting, Staff recommends that the Council hear the Staff
Presentation and accept public comment on each of the four major issues as the
issue is discussed and give direction before proceeding to the next issue.
