COUNCIL ACTION FORM
SUBJECT: SOLAR ENERGY SYSTEM USES TEXT AMENDMENTS
BACKGROUND:
Over the past year, public interest in installing small scale solar energy systems has
been expressed. However, current City codes only allow such systems in industrial
zoning districts. The City Council responded by directing staff to work with the Planning
& Zoning Commission to develop code provisions that more fully address solar energy
in all zones.
In fall of 2008, staff began researching this issue along with small scale wind systems
and presented its findings to the Planning and Zoning Commission in February of 2009.
The Commission found that one of the primary concerns is visual impact. Because of
the visual concerns, staff focused on ways to solicit public sentiment on the aesthetic
aspect of solar energy, and organized public meetings and workshops that used
graphical models and displays to illustrate what these systems may look like in different
settings. These meetings generated helpful information and feedback, which was used
in developing potential code changes pertaining to both solar and wind power.
The City Council reviewed the proposed concepts at a work session on August 18. The
Council determined that provisions for solar power were likely less complex or
controversial than wind power, and directed staff to bring forward a solar energy system
ordinance in advance of wind energy. The wind energy system ordinance will likely be
back to the City Council by late 2009 or early 2010.
At its meeting of September 16, the Planning and Zoning Commission made some
last minute changes to the ordinance. The only substantive change was the
elimination of the provisions for "Neighborhood Solar Energy Systems". This
provision was intended to facilitate a system on a vacant lot that would service
surrounding developed lots. However, the criteria in the proposed regulations focus on
solar energy as an accessory to a principal use when a principal building exists on a lot.
It was therefore determined that a stand-alone "neighborhood" system was inconsistent
with these criteria and would need further work. The Commission believed that this
could be addressed at some point in the future if the demand for such a system
becomes more apparent.
Staff informed the Commission at its September 16th meeting that the staff may make
some stylistic and format changes before sending this to the City Council to make sure
the document was consistent with the standard zoning code format. The Commission
agreed to this. Upon closer review, staff also identified some issues that resulted in
minor substantive changes, as follows:
1
• Eliminate provision that double-frontage and through lots would be afforded at
least one "rear yard" for setback purposes.
o Removed because the provision would be contrary to the intent of
avoiding views of systems from abutting streets.
• Eliminate requirement for an engineer to "wet-stamp" plans for roof mounted
systems.
o Removed because it was found that the City Building Official can
determine if engineered plans are needed through the standard building
permit process.
• Eliminate requirement for the applicant to certify that there are no subdivision
covenants preventing solar energy systems.
o Removed because these are private agreements not enforced by the city.
• Revise regulation of the type of signage that might occur on solar panels to
instead regulate the size of signage, now limited to one square foot per sign.
o Changed to ensure that the provision is content-neutral to avoid free
speech challenges.
• Eliminate regulations requiring non-reflective finish and subtle paint colors.
o Removed due to subjective nature of regulation. Color and finish might still
be addressed as part of a Special Use Permit. Staff approvals will not
regulate paint or surface textures.
• Clarify applicability in Old Town District.
o The proposed standards apply generally to all zoning districts of the City.
However, the Old Town District currently has restrictions within Chapter 31
on solar energy systems which require a Certificate of Appropriateness for
these systems. The standards were therefore changed to reflect this
requirement.
The proposed amendments are included in the attached draft ordinance. As drafted,
the proposed amendments will accomplish the following:
1. Add solar energy conversion as a permitted accessory use in all zoning
districts. This includes solar electric (Photovoltaic-"PV"), as well as solar thermal
(water heating). Both will be regulated with the placement standards.
2. Require that roof-mounted panels be mounted flush on homes, if visible from
the street.
3. Allow unlimited roof coverage in any zoning district if height standards are met.
4. Allow ground mounted solar panels to exceed square footage limits if not
visible from the street, or to be located in front yards only as approved through a
Special Use Permit.
5. Limit height of freestanding systems to four feet in front yards and six feet in
rear and side yards.

6. Provide limited flexibility for roof or wall mounted systems to encroach into
required side or rear setbacks.
7. Protect neighborhood character using dimensional standards and existing
historic preservation provisions.
8. Allow the potential for small scale systems to produce surplus electricity if an
Interconnection Agreement is signed by the property owner and the electric
utility.
9. Maintain existing building and fire safety standard requirements for trade
permits and licensed installation, when applicable.
The proposed amendments are consistent with and help to implement the following
goals in the City's Land Use Policy Plan:
• Goal 3 of "Goals for a New Vision," regarding "Environmental-Friendliness" is
supportive of this text amendment because the proposed amendments facilitate
property owners' desires to conserve traditional energy sources by installing solar
equipment on their property.
• Goal 4 of "Goals for a New Vision," regarding a "greater sense of place and
connectivity" and "assuring a more healthy, safe, and attractive environment" is
supportive of this text amendment because the proposal seeks to maintain the
attractiveness of the built physical environment. These amendments propose to
allow solar energy equipment in a way that is balanced with the character of the
surrounding built environment.
ALTERNATIVES:
1. The City Council can adopt the zoning code text amendments to Section 29.201,
Section 29.501(4)-4, Section 29.501(4)-7, and Section 29.1309, as described
above and contained within the attached ordinance document.
2. The City Council can adopt the zoning code text amendments to Section 29.201,
Section 29.501(4)-4, Section 29.501(4)-7, and Section 29.1309, as described
above, but with modifications.
3. The City Council can refer the minor substantive amendments made by staff
back to the Planning & Zoning Commission.
4. The City Council can choose not to adopt the proposed zoning code text
amendments.
5. The City Council can refer this issue to staff for further information.

MANAGER'S RECOMMENDED ACTION:
The proposed ordinance advances the Council's goal of going green and making Ames
a more sustainable community. In response to citizens wishing to install solar energy
equipment, the ordinance will provide clear standards for allowing these systems while
protecting surrounding properties. If interest grows in this field, the regulations may
later be amended as public awareness and acceptance of these systems in non-
traditional applications grows.
Therefore, it is the recommendation of the City Manager that the City Council accept
Alternative #1 and adopt the zoning code text amendments to Section 29.201(116),
Section 29.501(4)-4, Section 29.501(4)-7, and Section 29.1309, as described above
and contained within the attached ordinance document.
