Design Guidelines for Solar installations
On Historic Structures
Purpose
These Design Guidelines are established for the following purposes:
To supplement land use regulations which encourage and promote public health, safety
and welfare of the citizens of Port Townsend.
2. To provide guidance to uAan for design decisions that will promote development of high
environmental and visual quality and historical character throughout the City.
3. To assist applicants in the preparation of development applications.
4. To provide for administrative review by the Development Services Department (DSD) of
routine window solar device permit applications that satisfy guidelines adopted by the
Historic Preservation Committee (HPC) and the City Council.
Introduction
Across the nation, there is a rapidly growing trend toward retrofitting homes to be more energy
efficient. These efforts have seen solar panels and other solar devices, such as radiant water
heaters, becoming increasingly popular as the use of alternative energy sources become more
readily available to the general public.
When planning the installation of solar panels, the overall objective is to preserve character -
defining features and historic fabric while accommodating the need for solar access to the
greatest extent possible. All solar panel installations must be considered on a case by case basis
recognizing that the best option will depend on the characteristics of the property under
consideration.
For purposes of these guidelines, the term "solar devices" shall include solar panels, solar water
heaters, photovoltaic shingles, and any other installation that uses solar energy for mechanical or
electrical purposes.
Review Process
I. All solar device installations on historic residences designated as Secondary contributing
structures shall be reviewed administratively by DSD staff with a decision made by the
DSD Director.
2. Except where the guidelines below provide for administrative review, solar device
installations on all other structures subject to PTMC 17.30 (i.e. Pivotal and Primary
residences; all other commercial, public, religious and maritime trade buildings within
the historic overlay district; other structures determined by DSD to be historic that lie
outside the historic overlay district) shall be subject to Type I -A review and
recommendation by the Historic Preservation Committee (HPC) with a final decision
made by the DSD Director in a formal Certificate of Review.
Design Guidelines fog°Solar Installations
Guidelines
1. Installation of a solar device on a historic building is permitted only after other locations
on the subject property, such as an accessory outbuilding (whether historic or non -
historic), have been investigated and determined infeasible.
2. Where possible, solar devices shall be installed in a compatible location on the site or on
a non -historic building or addition where it will have minimal impact on the historic
building and its site.
3. Solar device(s) shall be installed on a historic building so that it is not visible or only
minimally visible from the public right of way. For example, on a flat roof set solar
panels back to take advantage of a parapet or other roof feature to screen solar panels
from view; or on a secondary slope of a roof, out of view from the adjoining public
rights-of-way.
4. On pitched roofs, solar roof devices shall be installed flat or parallel to the roof to
reduce visibility.
5. Solar device installations on the flat roofs of brick commercial buildings within the
historic overlay district shall be reviewed administratively by the DSD Director. In these
cases, solar devices may be installed at no more that 40° so long as the applicant
demonstrates that doing so will not cause the installation to be visible from the adjoining
rights-of-way.
6. Freestanding or detached on-site solar devices shall be installed in locations that
minimize visibility from the public right of way- and from neighboring properties. These
systems shall be screened from the public right of way with materials elsewhere in the
district such as fencing or vegetation of suitable scale for the district and setting.
Placement and design shall not detract from the historic character of the site or destroy
historic landscape materials. Gonsi6k-i rt;,,n 40 4114-o WNihilio, oar ft eestrn6414g NO/Oil6k-Viee
7. Solar device frame work and mounting systems shall be of a non -reflective color, such as
an anodized finish, that is compatible in color to established roof materials. Mechanical
equipment associated with the solar device system shall be treated as unobtrusive as
possible.
8. Trees in city right-of-way shall be preserved consistent with City code and not be topped
or removed to improve solar access to a property.

Comprehensive Plan Update: Thoughts/ideas
Community Direction Statement:
Under "a community with a sense of history and Place":
Revise the first sentence to read:
Founded in 1851, the City harbors a National IL..aigaJirnai-k Historic District and a wealth of superb
Victorian era homes, (:,oirnirner(,l4, ami :)uilkti gs, some of WNkh are recognized on the National
Historic Register.
Land Use Element:
Under Land Use Goals and Policies, add a policy that says:
Encourage the maintenance, re -use, and improvement of existing historic structures, both within
the National Landmark Historic District and throughout the other areas of the town.
Under "Residential Lands", add a policy that says:
Encourage the preservation of existing historic residential structures.
Under "Commercial Lands", add a policy that says:
Encourage the preservation of existing historic commercial and civic structures.
Housing Element:
Under "Housing Affordability", add a policy that says:
Encourage the preservation of existing large historic homes by allowing conversion to multi -family
use, or as boarding or rooming houses with shared kitchen and common areas.
Under "Housing Condition", consider a policy that would promote this idea somehow:
For historic structures that are either residential or contain a residential use, or with the potential
to contain a residential use, that are in deteriorating condition: create a program that would allow
the City to order a report, and if justified, the City could condemn and seize such buildings. The City
would auction the building to potential buyers that demonstrate interest and means to renovate
the building. The proceeds of the auction would go to the former owner, minus the cost of City
expenses.
Economic Develor)ment Element:
Under Goals and Policies, "Economic Development — Generally", add a policy:
Recognize the importance of Port Townsend's National Landmark Historic District, and the City's
inventory of historically significant houses and buildings, as one driver of economic development
for for the City of Port Townsend, and surrounding areas.
Under "Commercial Historic District Revitalization":
Revise Policy 7.3 to read:
Policy 7.3: Encourage the rehabilitation, renovation, and adaptive reuse of the elisVang Vbulilt

(e.g., for artist studios, permanent housing, and office space), which will contribute to the vitality of
the area.
Revise Policy 7.7 to read:
Policy 7.7: Recd „nze that the chairacteir of the CoinineirxliA III IistoiJc MstiJcts consists of the ei)Hira

chairacteir of the &sh Ict, G,....,... e-Feial H;ste-r;e—Pistri + public improvements accomplish the following
objectives: encourage pedestrian movement through the district and into shops and businesses,
and support, rather than overshadow, downtown functions.
Generally, and specifically in the section "Commercial Historic District - Implementation", change
the wording of "Commercial Historic District" to "Commercial Historic Districts" since there are
two: Downtown and Uptown.
