The Planning Director said the last meeting had ended with directions
for staff to look at another slope density formula. He then deferred
to Associate Planner Laurin.
Mr. Laurin noted the directions given had presented quite a task.
He exhibited and explained formula he had arrived at. He noted
that some conditions asked for were not compatible with each other
and he had not been able to work them out arithmatically.
Mr. Laurin then referred to graphs of slope density formula he had
distributed to commissioners. Copies were also distributed among
the audience.
The Associate Planner compared the wide -range curve with the Gatto-
Woodward, modified and rounded, curve, noting the Gatto-Woodward
curve would mean a decrease in dwelling units.
Mr. Laurin said it was reasonable to divide properties into different
areas, applying formula to each area. He had started to do this on
the church property, but had not quite finished. This would have
the effect of giving slightly higher density, but he felt it was
justified as the different terrains would be considered. Since his
study -was not complete, tre-coeid mane on₹y_ general -statement:
Comm. Adams asked Mr. Laurin for a rundown on one of the properties.
Mr. Laurin used the Seven Springs Ranch.. Using straight line, 492
dwelling units would be allowed; wide range formula, 475 and Gatto-
Woodward curve, 492. On the Seventh Day Adventist property there
could be 43, 30 and 42 dwelling units respectively. On Stella
Kester property, 78 units using straight line, 56 units using
wide -range formula and 38 dwelling units under Gatto-Woodward curve.
Comm. Woodward said his position in asking for modification was to
find a curve they could all agree on and which could be successfully
iterated. He felt a formula containing allowance for mixture of
terrain would give the developer more latitude. During computation
each property would be sectioned out.
Mr. Laurin said the latest formula has not introduced factor of
geological stability. If considered hazardous, there would be
a very fast reduction. Additional work would have to be done to
include this. Also the impact on vegetation and environment.
Comm. Cooper asked if the formula could not be expressed mathematically,
how it could be dealt with if not arbitrarily. Mr. Laurin said it
would have to be looked at arbitrarily to a certain extent to see
if it was the right development for each property; it must be checked
to see if it was environmentally sound. It was noted the present
ordinance gives this authority.

Comm. Gatto said he felt it was necessary to establish some unit
of measurement that could be applied uniformly. He asked Mr. Laurin
if increments of 200 x 200 would be feasible. Mr. Laurin said the
map could be easily computed in squares. The problem was there was
no map where property lines exactly match; will need actual survey
of certain reference points.
It was ascertained it would cost approximately $270.00 to have
250 acres of Regnart Canyon and part of Seven Springs Ranch
surveyed.
The break out point of the Gatto-Woodward formula for steepness
between 5% and 20% was discussed. A smoother curve at transition
was suggested.
With regard to rural residential and open space on Print 7, the
curve did not seem to be realistic with nature of terrain. It
was agreed the rural residential could be used by itself.
Comm. Woodward said the penalties of Gatto-Woodward curve are
much too severe; he liked the line curved at end.
Comm. Adams questioned whether they should stay with wide -range
formula at high slopes. This would avoid conflicts with majority
of hazardous ground areas it will be necessary to look at.
In answer to Comm. Adams, Mr. Laurin said it would be an enormous
amount of work to determine how many acres of different slope
densities if not using computer.
The meeting was then opened for public comment.
Mrs. L. D. Hertet, San Juan Road, asked at what point would other
considerations, such as trees, waterways, unstable lands, etc.,
be computed. She was answered that it would not be difficult to
adjust density to the vegetation and terrain after formula has
been established.
Slope density maximums and minimums were discussed. The minimum
would always be zero. Comm. Woodward noted a lot depended on the
ingenuity and feel of the developer for the property.
Comm. Gatto said they should develop basic slope density formula
and address policies to evaluate other items, making a policy
statement spelling these things out with each category addressed.

IMIr. William W. Crowell, president of Inwood Corporation, 900 Welch
Road, Palo Alto, said he was representing the Archdiocese of St.
Joseph property. He wondered how the Planning Commission felt
about transfer of density, considering peculiarity of St. Joseph
set back. He asked if developer through formula would be encouraged
to build whole property or to cluster on 395 acres. He noted it is
a large property and that the large hillside acts as open space.
Mr. Laurin said the County has approached same question, and said
that credit could be transferred for dwelling units from one to
another within the limitation that at no point is maximum density
of curve exceeded. He felt there should be some way you could
exceed that density under certain conditions.
Comm. Woodward said he felt this had been agreed to all along; this
must be addressed on each specific property. The Planning Director
noted this was an important point.
Comm. Gatto said the reason for slope density formula was to provide
how much density there would be on hillside. The ingenuity of the
developers would be respected and open to fair amount of schemes as
to how units were placed on land. The character of area and nature
of building will be considered in maTcing�ecision. On large size
properties there could be the possibility for combination of uses.
Comm. Cooper felt this point needs to be stressed by the Commission.
Clustering had been talked about in terms of bonuses; this is trans-
ferring of units. The Commission needs to address in policy state-
ment the character being sought in foothills in terms of general
over-all policy, total aesthetics and total usage.
Comm. Adams said with regard to allowing density limitation to be
exceeded, he could go along to a point. He favored more the County's
point of view. He would hesitate allowing maximum to be exceeded to
any extent.
Chairman O'Keefe said he believed they should be flexible. There must
be protection for trees, streams and environment. With some cluster-
ing there would be less streets and less scarring of hillside.
Comm. Woodward referred to availability of a wide range of housing. The
Catholic church property and Seven Springs Ranch are excellent
opportunities for range and mix of housing.
Ms. Hertet asked if maximum would be allowed even though it would
create destruction. Chairman O'Keefe said each. site must be
developed en its merits. It cannot be forced. All factors must
be considered and it must be compatible in every way.

Mr. Lamont E. Williams, 514 Inverness Way, Sunnyvale, said they had
been before the City of Cupertino with two plans. Their biggest
problem was to make compatible requirements of Public Works and
Planning Commission. Some balance should be brought into the picture,
The individual character needs to be looked at on each acre in the
entire property. This is a big job but the only way to come to
aesthetics wanted. There are so many variables, the City must
look at each piece of property.
Mr. Alvin Anderson representing Seventh Day Adventist property said
they were mainly interested in seeing finished study on their piece.
He ascertained that the idea of 4.4 is the established maximum. He
noted there are duplexes around their property on several sides. He
thought their density should be more than 4.4 since that is what is
already there. He hoped they wouldn't be ruined too much.
Comm. Woodward said with a mixture of units on this property there
could be a higher density in some parts of property. It would seem
reasonable to use possibility of transferring densities.
A summary of discussion on slope density was made. There would be
some kind of computer mapping of hills, breaking property down into
one acre parcels. Mr. Sisk noted there might be a way through fees
on hillside properties to get some of the money back.
Comm. Gatto noted there were three areas to cover: (1) formula
of slope density curve, (2) incremental units, and (3) set of
policy statements. He noted the straight line was not detrimental
if using incremental units.
Comm. Gatto asked if the commission was in basic agreement of taking
wide -range formula extending to flat range 0-5 at top. 0-5 would have
4.4 dwelling units; straight line to 20% slope at 1.75 unit per acre.
The point to raising question was whether they should widen back out
to Gatto-Woodward curve or go to the wide -range curve.
Comm. Woodward noted at 35% slope there would be a severe penalty if
the wide range curve was used below the 20% slope point. He suggest
fairing out to Gatto-Woodward curve at this point.
Comm. Gatto noted a 30% to 40% slope on the wide range curve, takes
20 acres to put one house; Gatto-Woodward curve would take 2 1/2 acre
for one house which doesn't seem to be unreasonable. It might have
significant impact for a single property even though would not be a
large number for entire hillside.

Comm. Woodward said he favored cutting off flat at 20% slope
fairing out to Gatto-Woodward curve at 35% slope. He noted
in urban service area they will be encouraging clusters.
The commission agreed with the provision that all conditions
shall be included in policy statement.
Staff was to study cost of computerized mapping of the hillsides.
Regarding size of squares, 200 x 200 vs 100 x 100, Mr. Laurin
said the property owner would prefer 100 x 100. He noted there
should be a certain map quality. A case study of one piece of
land would be done and costs of both systems compared.
Comm. Gatto listed the following areas to be covered in policy
statement:
... Clustering
... Geological consideration
... Ridges: which would be more important than others
Stream beds and waterways
Water shed areas
... Treatment of traffic arteries�sh5iirdfaads b60Tt.
or less)
... How vegetation should be handled
... Statement of building statutes and how existing parcels
that are less than allowed could be treated
... Countable land
... Social goals
... Density transfer
... Land uses other than residential
It was agreed to hold a special meeting on November 20, 1974, at
which time staff would have formula and policy statements for
hillside study available.
Comm. Woodward asked if land slide areas on which no building would
be allowed would be countable land for density transfer; also the
same question on creep areas. It was, ascertained there must be a
certified engineering report that mitigations could be made for
creep areas. He felt these two areas should be addressed. The
commission agreed.

Mr. W. J. Herman said he was considering buying Kester property.
He had plans and application being held in abeyance. He said
there was a problem on getting EIR started, but there was a time
limit on purchase contract. He asked if this parcel could be
one of the samples worked on so that he could reach a decision.
The commission assured him of their assistance.
Comm. Cooper asked Mr. Laurin about increments for grids. She
would like a total on land and a total on whole hillside according
to the formula agreed on tonight.
Mr. Sisk said he would have discussion questions prepared for each
policy statement.
It was agreed the rural residential curve would be used, outside the
urban service boundary.
At 9:30 p.m. Comm. Gatto moved, seconded by Comm. Adams, to adjourn
to the meeting of November 20, 1974.
