Mayor Pro-tem Carolyn Powers called the Council of the City of Port Orchard, Washington, to order in
special session at 7:30 P.M. at City Hall, 216 Prospect Street.
Council members present: Clauson, Wyatt, Morrison, Geiger, Powers, Van Zee, and Stansbery.
Staff present: City Engineer Curies and City Clerk Parks.
Mayor Pro-tem Powers reopened the Draft Zoning Ordinance Public Hearing which was continued from
March 5, 1998. The purpose of holding a series of continued meetings that constitute one public hearing is
to allow a detailed and thorough review and discussion on the Draft Zoning Ordinance. Public input is
invited and encouraged during discussions on the Draft Zoning Ordinance.
Mayor Pro-tem Powers requested City Engineer Curles facilitate continued discussion of Section D4
Landscaping.
City Engineer Curles stated he would like to address two pending issues which the Council has requested
staff review. The first items is Section 8 Street Trees (subsection b -Page 197). Staff recommendation is
to delete a portion of this subsection to simplify future interpretation. By general concensus Council
members concurred on revision of Section 8 b to read as follows: b: Street tree species, where not
designated in accordance with a design overlay district's requirements, may be selected from the
suggested landscape materials list and shall be subject to the review and approval of the City Engineer. -ef
The second area staff input was requested is Section 11: General Landscaping requirements, subsection
)j . As written subsection j" could result in berms measuring up to 24 feet. This could significantly impede
development of smaller lots, which other wise are buildable. After discussion Council members agreed to
revise subsection j to read: j: Berms shall should not exceed a slope of 2 horizontal feet to one vertical foot
(2:1), unless there are extenuating circumstances.
At this time, focus of Council review and discussion returned to the point where they had stopped
discussion at their last meeting Mara 5, 1998. Council by general concensus, agreed on the following
revisions to the remaining sections of Chapter D4 Landscape standards:
Section 12: Aleemative options
The following alternative landscape options may be allowed only if they accomplish equal or better levels of
screening and are subject to the review and approval of the City Engineer:
a:
Total required
landscape and tree retention area will not exceed 15 percent of site area.
b: No change.
c: Perimeter landscaping may be reduced up to 25 percent when a development retains an additional 10
percent of the existing significant trees or 10 significant trees per acre on -site (above the requirements for
tree retention defined within this chapter), whichever is greater.
d: No change

e g: A grouping of 3 or more existing healthy trees with canopies that touch or overlap, may be substituted
for each required significant tree, provided each tree has a diameter of at least 3 inches when measured 4
feet above grade.
f t}: Except as provided in subsection i following, significant trees to be retained shall not include significant
