to deteriiiine the actual wetland boundaries was conducted according to the methodology
outlined in the Washington State Wetland Identification and Delineation Manual Department
of Ecology #96-94}, Chapter 173-22 of the Washington Administrative Cade requires
that all wetlands within the State of Washington be delineated using this manual. All critical
areas within the City of Port Tov~nsend are regulated according to the Fort Townsend Municipal
Code Critical Codes Ordinance {N0.2899, July 2005 PTMC}.Description
of Site Legal
Description: Parcel #964 200 701 {702} Section 4 Township 34N Range 1 W Location:
2827 Katherine St. (undeveloped) North of Hastings St and West of Thomas St.Soils:
TuC Tukey gravelly loam and CmC Clallarn gravelly sandy loam Slopes:
0 to 1 S% slopes The
parcels are located near a portion of the wetland described by Palazzi in 1994 as Deering Wetland (
WL#9-1). Deering Wetland is located at the top of Basin 9. This wetland is contiguous
with North Deering Wetland (WL#5-4} located at the top of Basin 5. Although the dividing
point between the two wetlands is unclear, due to the flat topography, it has been categorized
as one wetland. Open pastures, roads, and development have fragmented this large seasonal
wetland.Level

Findings
An arm of the Deering. Wetland extends down the undeveloped section of 29a` Street to within
55 feet of the northeast corner of parce1 964 200 702. A drop in topography and a dominance
of wetland vegetation, which includes slough sedge, willows, and spires, def nes the wetland.
The wetland edge was not delineated during this Level I Assessment. Using the Department of
Ecology Wetland Field Data Farm {04-06-025) this wetland rates as a Category II wetland (52
points). All Class II wetlands with a moderate to low level far habitat function receive
protective buffers of 100 feet. Enclosed is the Wetland Rating Forrn. The wetland was
previously was rated as a Category II wetland by Palazzi.
It is therefore not recommended that Katherine Street (within 100 feet of the wetland} or 29t~'
Street {in the wetland) be developed. Please f nd the enclosed map with findings from the
Level I Assessment.
Currently the understory vegetation has been cleared on the majority of parcel 964 200 702 and
along Katherine Street. The large trees are still present. I~•lounds of soxl`have-'been inpol-tecl`to

Final authority over wetland determinations and associated buffers rests with the City of Port
Townsend Development Services Department. If this project requires a delineation to
determine exact wetland edges or if further restoration design is required please don't hesitate
to call.

Katherine street Wavier
Sir,
Brush Bearing to install the engineered septic system and complete a survey of the Katherine Street extension
inconjunction with the construction of my rtev~+ home at, 2829 Katherine Street, have revealed a new portion of the
herring Wetland," The wetland extension was hat previously plated on -the City of Pcrt Townsend Wetland Invarrtor-y Map
and as a result of this discovery I have carrtracted the services of Ms, nixie I.Iewllin, of Olympic Wetland pescrces to
complere a Leval I Assessment of the pOW and nearby area, and her fndings are enclosed,
the wetland area is located near the intersection of the Katherine and 29th Sty-eet pOW's where f have proposed to
install a septic system and street/ waterline extensia~, Preservation aFthis critical stormwater and wildlife habitat
according to her assessment wdl require reavauluation of the street extension and septic Installation as proposed,
fherefore I am requesting a wavier be granted from the City of Port Townsend ~ngineerinq and I?esign standards, The
100' setbacks sugested by the wetlands assesment will prevent the installation of a paved street and turn around in
the Katherin 5txeet I:OW, and make ,t difficult to Install the septic system as approved, While the septic system can be
relocated on the site I would wonder abort the wisdom of installing a new septic system In such close prox~mlty to an
Gnviromerrtaliy Sensitive Area we are attempting to preserve in perpetuity, ~eviewinq these complex issues I would like to
propose the necessary infastructure be developed in the least Invasive manor possible to insure the protection of fragile
wetland and provide necessary fire aces and utilities far Public Safety.
To achieve the goals } would propose that I be a1 lowed to install a 2-3"pressure line from my property to an existing
manhoe approximerrrly 520' North in the Katherine & 31st Street t?OW< The route would utilize 29th Street West of
Katherine and then North to 31st In Katherine avoinding the proposed wetland buffer, In addition, It could be constructed
in a mininmally invasive 5- 6' wide excavation and provide an opprtunity to relocate a foot path that currently Intrudes
into the wetland at the 30th and 'Thomas Street pOW, Topo prevents the installat€on of a gravity sewer line much more
than 75'sarth of the current manhole, In the event that future Bevelopmerrt occures and gravity sewer is installed any un
lecessary portion of the pump line could be abbonded and the line reconnected to the new sewer.
FI Pire Nydrarrt is located at Thomas Streets 260' from my driveway entrance and is adequate to serve the property,
Water service is anal cable in Hastings Avenue and a meter installed in Hastings similar to the neighboring properties wool d
be an adequate and efflclartt way to obtain snaitary water Tlnls property as well as the neighboring Mcl7onald property
2/9/200G KATHERINE STREET WAVIER
are ccurrer~tly served by an exfi~tinq gravel driveway and I would regueyt a variance from the Street l7evelopmerrt
Standards to utilize +,he existing driveway as it appears that Katherine Street between 28th and 29th will never serve
more than 2 properties because of the proximity of the ad~acenr wetlands, furthermore, my property has already been
bound together by a recorded notice to title, I would also grant a "No protest" to participate in any bll?'s a- other
infastructure improdememnts that would affect my property,
thank you for you cony~deration and pfease call if I can answer any further quest~on5,
r`'espectfully,
C-
