18.70.010 PURPOSE AND INTENT. The purpose of the Solar Access chap-
ter is to provide protection of a reasonable amount of sunlight
from shade from structures and vegetation whenever feasible to all
parcels in the City so that the economic value of solar radiation
falling on structures is preserved, investments in solar energy
systems may be secure, and the options for future uses of solar
energy will be preserved.
18.70.020 DEFINITIONS.
A. Exempt Vegetation. All vegetation over 15 feet in height at the
time a solar access permit is applied for.
B. Highest Shade Producing Point. The point of a structure wh:ich
casts the longest shadow beyond the northern property boundary
at noon on December 21st.
C. Natural Grade. The elevation of the natural ground surface in
its natural state, before man-made alterations. The natural
ground surface is the ground surface in its original state,
before any grading, excavation, or filling.
D. Northern Lot Line. Any lot line or lines less than 45 degrees f
southeast or southwest of a line drawn east-west and intersecting'
the northernmost point of the lot. If the northern lot line
adjoins any unbuildable area (e.g. streets, alleys, public
rights-of-way, parking lots, or common areas) other than a re-
quired yard area, the northern lot line shall be that portion of
the northerly edge of the unbuildable area which is due north
from the actual northern edge of the applicant's property.
Staff Draft, revised March 14, 1985
Page 1
E. North-South Lot Dimension. The average distance in feet
between lines from the corners of the northern lot line south
to a line drawn east-west and intersecting the southernmost
point of the lot. .
F. Solar Energy System. Any device or combination of devices or
elements which rely upon direct sunlight as an energy source,
including but not limited to any substance or device which col-
lects sunlight for use in: the heating or cooling of a structure
or building; the heating or pumping of water, or the generation
of electricity. A solar energy system may be used for purposes
in addition to the collection of solar energy. These uses in-
clude, but are not limited to, serving as a structural member or
part of a roof of a building or structure and serving as a window
or wall.
G. Solar Envelope. A three dimensional surface which covers a
lot and shows, at any point, the maximum height of a permitted
structure which protects the solar access of the parcel(s) to
the north.
H. Solar Heating Hours. The hours and dates during which solar
access is protected by a solar access permit, not to exceed
those hours and dates when the sun is lower than 24 degrees
altitude and greater than 70 degrees east and west of true
south.
I. Solar Access Permit Height Limitations. The height limitations
on affected properties required by the provisions of a Solar
Access Permit displayed as a series of 5 foot contour lines which
begin at the bottom edge of the solar energy system protected by
the permit, rise at an angle to the south not less than 24
degrees from the horizon, and extend at an angle not greater than
70 degrees to the east and west of true south and run parallel to
the solar energy sytem.
J. Solar Setback. The minimum distance that a structure, or any
part thereof, can be located from a property boundary.
K. Slope. A vertical change in elevation divided by the
horizontal distance of the vertical change. Slope is measured
a~ong lines extending 150 feet north from the end points of a
ll~e drawn parallel to the northern lot line through the mid-
pOlnt of the north-south lot dimension. North facing slopes
will have negative (-) values and south facing slopes will
have positive (+) values.
L. Sunchart. Photographs or drawings, taken in accordance with
the guidelines of the Staff Advisor, which plot the position of
the sun during solar heating hours. The sunchart shall contain

degree increments and solar aZ1muth measured from true south 1n
15 degree increments. If the solar energy system is less than 20
feet wide a minimum of one sunchart shall be taken from the
bottom edge of the center of the solar energy system. If the
solar energy system is greater than 20 feet wide a minimum of two
suncharts shall be taken, one from the bottom edge of each end of
the solar energy system.

18.70.040 SOLAR SETBACKS
(A) SETBACK STANDARD A
This setback is designed to insure that shadows are no greater than
six(6) feet at the north property line.
Buildings on lots ~1ich are classified as Standard A, and zoned for
residential uses, shall be set back from the northern lot line
according to the following formula:
H - 6'
SSB =
0.445 + S
WHERE:
SSB = the minimum distance in feet that the tallest shadow
producing point which creates the longest shadow onto tpe
northerly property must be set back from the northern
property line.
H = the height in feet of the highest shade producing
point of the structure which casts the longest
shadow beyond the northern property line.
S = the slope of the lot, as defined in this Chapter.
(B) Setback Standard B
This setback is designed to insure that shadows are no greater than
sixteen(16) feet at the north property line.
Buildings for lots which are classified as Standard B, or for any lot
zoned C-l, E-l, or M-l, or for any lot not abutting a residenti~l
zone to the north, shall be set back from the northern lot line'
as set forth in the following formula:
H - 16'
SSB =
0.445 + S
lfl Setback Standard C
This setback is designed to insure that shadows are no greater than
twenty-one(2l) feet at the north property line.
f f
Buildings for lots in any zone whose north/south lot dimension is
less than Standard B shall meet the setback set forth in the fol-
lowing formula:

CD> Exempt Lots
Any lot with a slope of greater than .30 in a northerly direction,
as defined by this Ordinance, shall be exempt from the effects of the
Solar Setback section.
(E) Lots Affected By Solar Envelopes
All structures on a lot affected by a solar envelope shall comply
with the height requirements of the solar envelope.
(F) Exempt Structures
1. Existing Shade Conditions.
If an existing structure or topographical feature casts a shadow
at the northern lot line at noon on December 21, that is greater
than the shadow allowed by the requirements of this Section,
a structure on that lot may cast a shadow at noon on December 2l,
that is not higher nor wider at the northern lot line than the
shadow cast by the existing structure or topographical feature.
This section does not apply to shade caused by vegetation.
2. Actual Shadow Height.
If the applicant demonstrates that the actual shadow which would
be cast by the proposed structure at noon on December 2l, is no
higher than that allowed for that lot by the provisions of this
Section, the structure shall be approved. Refer to Table D...for
actual shadow lengths.
18.70.050 SOLAR ACCESS PERFORMANCE STANDARD
A.
Assignment 9f Solar Factor All land divisions which create
new lots shall be designed to permit the location of a 21
foot high structure with a setback which does not exceed
50% of the lot's north-south lot dimension. Lots having
north facing (negative) slopes of less than .l5 (e.g..lO),
and which are zoned for residential uses, shall have a
north-south lot dimension equal to or greater than that
calculated by using Formula I. Lots having north facing
(negative) slopes equal to or greater than .l5 (e.g..20),
or are zoned for non-residential uses, shall have a north-
south lot dimension equal to or greater than that calcu-
lated by using Formula II.

B.
Solar Envelope If the applicant chooses not to design a
lot so that it meets the standard9 set forth in (A), above,
a Solar Envelope shall be used to define the height re-
quirements which will protect the applicable solar access
standard. The Solar Envelope, and written description of
its effects, shall be filed with the land partition or
subdivision plat for the lot(s).
18.70.060 VARIANCES
A. Any variances to this Chapter shall be processed as Type I
procedures.
B. In addition to the findings for a variance contained in Chapter
18.100, a variance may be granted with the following findings being
the sole facts considered by the Staff Advisor:
1. That the owner or owners of all property to be shaded,' sign
and record with the County Clerk on the affected properties
deed, a release form supplied by the City, which contains
the following information:
a. The signatures of all owners or registered lease hold-
ers who hold an interest in the property in question.
b. A statement that the waiver applies only to the specific
building or buildings to which the waiver is granted.
c. A statement that the solar access guaranteed by this
Section is waived for that particular structure and the
City is held harmless for any damages resulting from the
waiver.
d. A description and drawing of the shading which woutd
occur, and
2. The Staff Advisor finds that
a. The variance does not preclude the reasonable use of
solar energy on the site by future buildings, and
b. The variance does not diminish any substantial solar
access which benefits a habitible structure on an
adjacent lot.

visions of Section 18.70.080.
18.70.080 HEARING PROCEDURE
A. The Staff Advisor shall send notice of the hearing on the
permit application to the applicant and to all persons originally
notified of the solar access permit application, and shall
otherwise follow the procedures for a Type I hearing.
B. The Staff Advisor shall consider the matters required for appli-
cations set forth in Section l8.70.070(B) on which the applicant
shall bear the burden of proof, and the following factor on which the
objector shall bear the burden of proof: a showing by the obj~~tor
that the proposed collector would unreasonably restrict the planting
of vegetation of presently under-developed property.
If the objector is unable to prove these circumstances and the appli-
cant makes the showings required by Section l8.70.060(B), the Staff
Advisor shall approve the permit.
If the applicant has failed to show all structures or vegetation
shading of the proposed collector location in his application, the
Staff Advisor may approve the permit while adding the omitted
shading structures or vegetation as exemptions from this Chapter.
If ~he objector shows that an u~conditional approval of the appli-
catlon would unreasonably restrlct development of the objector's
presently under-developed property, the Staff Advisor may approve the
permit, adding such exemptions as are necessary to allow for

t.
reasonable development of the objector's property.
If the Staff Advisor finds that the application contains inaccurate
information which substansially affects the enforcement of the solar
access permit, the application shall be denied.
C) Any decision by the Staff Advisor may be appealed to the Planning
Commission and the City Co unci! as a Type II planning action
according to the usual procedures contained in this Title.
18.70.090 LIMITS ON SOLAR ACCESS PERMITS.
A. No Solar Access Permit may be filed which would restrict any
lot which has an average slope of .15 in the northerly direction.
B. A Solar Access Permit becomes void if the use of the solar
collector is discontinued for more than 12 consecutive months
or if the solar collector is not installed and operative within
12 months of the filing date of the Solar Access Permit. The
applicant may re-apply for a Solar Access Permit in accordance with
Chapter 18.70.070 of this Title, however, the application fee shall
be waived.
18.70.100 ENTRY OF SOLAR ACCESS PERMIT INTO REGISTER.
A. When a solar access permit is granted, the Staff Advisor
shall:
1) File the solar access permit with the County Clerk. This
shall include, the owner's name and address and tax lot of the
property where the recorded collector is to be located,
any special exceptions or exemptions from the usual affects
of a solar access permit, and the tax lots of the ten or fewer
adjacent properties subject to the solar access permit.
2) File a notice on each affected tax lot that the solar.~
access permit exists and that it may affect the ability of the
property owner to grow vegetation, and that it imposes certain
obligations on the property owner to trim vegetation.
3) Send a certified letter, return receipt requested, to the
app~icant and to each owner and ~egiste~ed lessee of property
subJect to the solar access perm1t stat1ng that such permit
has been granted.
B. If a solar access permit becomes void under Section
l8.70.090CB), the Staff Advisor shall notify the County Clerk,

18.70.110 EFFECT AND ENFORCEMENT
A. No City department shall issue any development permit purporting
to allow the erection of any structure in violation of the setback
provisions of this Chapter.
B No one shall plant any vegetation that shades a recorded collec-
t~r, or a recorded collector loc~tion if it is not yet.instal~ed,
after receiving notice of a pendlng solar access permlt appll-
cation or after issuance of a permit. After receiving notice of
a solar access permit or application, no o~e shall permit any
vegetation on his or her property to grow ln such a manner as to
shade a recorded collector (or a recorded collector location if it is
not yet installed) unless the vegetation is specifically exempted
by the permit or by this Ordinance.
C. If vegetation is not trimmed as required or is permitted to grow
contrary to Section l8.70.100(B), the recorded owner or the City, on
complaint by the recorded owner, shall give notice of the shading by
certified mail, return receipt requested, to the owner or registered
lessee of the property where the shading vegetation is located. If
the property owner or lessee fails to remove the shading vegetation
within 30 days after receiving this notice, an injunction may be
issued, upon complaint of the recorded owner, recorded lessee, or
the City, by any court of jurisdiction. The injunction may order
the recorded owner or registered lessee to trim the vegetation, and
the court shall order the violating recorded owner or registered
lessee to pay any damages to the complainant, to pay court costs,
and to pay the complainant reasonable attorney's fees incurred
during trial and/or appeal.
D. If personal jurisdiction cannot be obtained over either the
offending property owner or registered lessee, the City may have a
notice listing the property by owner, address, and legal description
published once a week for four consecutive weeks in a newspaper of
general circulation within the City giving notice that vegetation
located on the property is in violation of this ordinance and is
subject to mandatory trimming. The City shall then have the power,
pursuant to court order, to enter the property, trim or cause to have
trimmed the shading parts of the vegetation, and add the costs of the
trimming, court costs, and other related costs as a lien against that
property.
E. In addition to the above remedies, the shading vegetation is f
declared to be a public nuisance and may be abated through Title 9 of'
the Ashland Municipal Code.
F. Where the property owner or registered lessee contends that
particular vegetation is exempt from trimming requirements, the bur-
den of proof shall be on the property owner or lessee to show that an
exemption applies to the particular vegetation.
