Agenda Request
To: Board of Commissioners
Mark McCauley, County Administrator
From: Monte Reinders, Public Works Director/County Enginee/J .
Agenda Date: August 1, 2022
Subject: Open Right-of-Way Request - Charles St.
Statement of Issue:
Public Works has received an application to open a portion of platted Charles St.
right-of-way for approximately 600 feet for access to the Applicant's parcel.
Analysis/Strategic Goals/Pro's a Con's:
The proposed area of right-of-way to be opened is located within the Plat Irondale Acre
Tracts. This road is not proposed to be a County Road, therefore the County will not be
responsible for maintenance should this request be approved.
Per RCW 36.80.030, the supervision of right of way, including the development of road
standards is under the review of the County Engineer, acting under the supervision and
authority of the Board of County Commissioners. The County Engineer has prepared standards
for opening County right-of-way at this location as outlined in the attached report.
Fiscal Impact/Cost Benefit Analysis:
There will be no cost to the County for maintenance or construction should this right-of-way
be opened.
Recommendation:
Jefferson County Public Works recommends approval of this application to open a portion of
platted Charles St. for approximately 600 feet, and upgrading a portion of Kingfisher Pl. from
the end of the County maintained road segment as outlined on the attached Engineer's
Report. The Board is asked to sign the Resolution and return to Public Works.

County Engineer's Report
Open Right -of -Way Portion of Platted Charles St., Irondale Acre Tracts
This Report is in response to an Open Right -of -Way Permit application (Exhibit A) submitted by
Shawn Behrenfeld. The intent of the County Engineer's Report is to evaluate and provide
preliminary design parameters/criteria to facilitate the appropriate design of the project. After
agency approval of all documents required by this report the applicant shall be issued a permit
by the Public Works Department.
PROJECT DESCRIPTION
Plat name: Irondale Acre Tracts
Road / Street Name: Platted Charles St.
Adjacent to: Assessor Parcel #962700023 & 901132001
Distance: Approximately 600 feet
Sections 34, Township 30 North, Range 1 W
The road is not proposed to be a County Road (Exhibit B = Site Plan).
EXISTING CONDITIONS
This Permit would officially open a segment of platted Charles St. right-of-way (subject ROW) to
provide access to the Applicant's parcels #901132002,
The access to this segment of Charles St. will come off the private segment of Kingfisher PI. at
the end at mile post 0.37 left at a 90 degree angle and run southerly for approximately 630 feet
to an easement established along the southerly line of parcel #901132001 which provides
access to Applicant's parcel #901132002. This area of right-of-way has been improved without
permits with a 9 foot wide drivable area. The improvements to this right-of-way of platted
Charles St. was done sometime after 2010 when the private segment of Kingfisher PI. was
developed under an open right-of-way permit (RAP2009-00053). The Engineer's Report for this
2009 open right-of-way permit called for two 9-foot wide lanes and 2-foot shoulders. The
segment of Kingfisher PI. connecting to the end of the County maintained road segment will be
upgraded and improved to the road standard that will apply to this request.
There is potential for this currently proposed segment of right-of-way to be used as access to
parcel #901131001 owned by Pope Resources. This parcel is designated forest land and past
logging activities have routed the logging roads to Oak Bay Rd.
A pre -application conference was held (PRE2021-00036) regarding the potential use of
Applicant's parcel(s) to "create affordable community -living options for local trades and trade
schools in Port Hadlock / Port Townsend and design off -campus educational experience".
Page 1 of 7
The owners of 962700022 located at 356 Kingfisher PI submitted comments regarding the
opening of this segment of Charles St. (See Exhibit 1).
DESIGN STANDARDS
Roads shall be constructed to the County's adopted County Road design standards:
e American Association of State Highway and Transportation Officials (AASHTO) Policy on
Geometric Design of Highways and Streets (most current version),
A Washington Department of Transportation (WSDOT) Design Manual and Standard
Specifications for Road, Bridge and Municipal Construction,
• Jefferson County Unified Development Code JCC 18.30.060 Grading, JCC 18.30.070
Stormwater, and JCC 18.30.080 Roads.
Based on proposed use and the topography, it is not likely that this right-of-way will connect to
other platted rights -of -ways within Irondale Acre Tracts. A pre -application conference
(PRE2021-00036) was held on 1-18-2022 regarding potential development. At that time the
Applicant indicated he would like to provide housing for students that attend local schools (Le,
Wooden Boat School), and future building type classes on site taught by the Applicant. This
may provide for future development up to 400 ADT. The Applicant has expressed his desire to
build the road to the higher standard rather than make improvements at a later date.
Therefore, the minimum typical section required for Charles St. and Kingfisher Pl. will be for a
"Local Access Road" (see Exhibit C). The request to open this proposed segment of road is not
for a county maintained roadway, therefore, it is not required to be paved and the applicant
will be responsible for the maintenance of this section of roadway.
RIGHT-OF-WAY
Platted right-of-way width: Sixty feet is the AASHTO recommended ROW width in rural county
areas. The current ROW width as platted is 60 feet. This width appears adequate in this case.
Right-of-way centerline location
Roadways shall be constructed on the right-of-way centerline unless this is not feasible due to
topography, environmental conditions (e.g., wetlands, water bodies, unstable slopes), or
transitions to existing roads.
Prior to construction, the right-of-way centerline shall be staked by a licensed professional land
surveyor or located in the field based on existing monuments or property corners set by a
licensed professional land surveyor.
DESIGN SPEED
Speed limit may be less than 25
This is a privately maintained dead-end road on public right-of-way, and no posted speed limit
is required.
Page 2 of 7
DESIGN TRAFFIC VOLUME
The projected Average Daily Traffic (ADT) per residence is between 6-10 trips per day.
However, based on the proposed build out at a pre -application conference (PRE2021-00036),
the Applicant stated he would like to provide housing for students attending trade schools in
the area which may increase the ADT up to 400. At present, opening Charles St right-of-way
would provide access through an easement road to two parcels owned by the Applicant (Queen
Ann Plat 20 +/- acres and a 120 acre parcel #901132002). Additionally, there is potential to
access three other parcels when this right-of-way is opened. These include a 260 acre
designated forest parcel owned by Pope with access off Oak Bay Road, a 20 acre parcel with
which the private easement road goes through, and a 5 acre parcel which presently has access
off Kingfisher Pl.
SIGHT DISTANCE
Adequate sight distance must be met based on the criteria within the WSDOT design manual,
Chapter 1340 and/or the AASHTO design manual.
ROADWAY CONSTRUCTION PLANS
The proponent shall construct the roadway to the minimum standards depicted on the Typical
Section shown in Exhibit C.
The proponent shall submit road construction plans prepared and stamped by a licensed civil
engineer to the Public Works Department for review prior to commencing construction.
Road Construction Plan general requirements

Page 3 of 7
Profile View
The profile view shall at a minimum depict:
• Existing elevations and proposed finished grades at 50 feet stations;
• Vertical curve data; and
■ Drainage facilities.
MINIMUM STRUCTURAL SECTION
Privately -maintained roads: The typical cross-section consists of 6 inches compacted gravel base
over compacted subgrade, 4 inches compacted crushed surfacing base course, and 2 inches
compacted crushed surfacing top course. An asphalt surface will not be required. An alternative
structural section may be proposed based on analysis by a licensed civil engineer.
All materials used in the construction of the structural section shall meet the requirements of
the WSDOT Standard Specifications for Road, Bridge and Municipal Construction.
SURFACING
Privately -maintained roads: An improved roadway surface (asphalt or bituminous surface
treatment) is not required.
MATERIALS TESTING
Privately -maintained roads: The applicant shall be responsible for ensuring that materials and
construction methods conform to WSDOT Standard Specifications. At its discretion, the Public
Works Department may direct replacement of materials that clearly do not meet specifications or
require testing of materials that appear not to meet specifications.
CROSS SLOPES
Local Access Roads shall either be crowned at 2% on centerline, or, 2% across the full width of
the road.
ROAD GRADE
Privately -maintained roads:
• Road grades shall not exceed 12% without prior approval by the appropriate Fire District.
• Roads grades exceeding 12% may require an improved roadway surface, either hot mix asphalt
(HMA) or bituminous surface treatment (BST).
• Road grades shall not exceed 15%.
EMERGENCY TURNAROUNDS
Turnaround area(s) are required and shall conform to the Public Works Department's adopted
design standards. See Exhibit C.
HORIZONTAL CLEARANCE TO OBSTRUCTIONS
For roads with a posted speed limit of 25 MPH or less, a 10 feet wide clear zone shall be
maintained between the edge of traveled way and any obstructions.
Page 4 of 7
UTILITIES
Utility installations shall meet the requirements of the Jefferson County Code, Chapter 13.56
Utilities. Any utilities installed within the right-of-way require review and approval for
installation and location within the right-of-way as determined through the utility permit
process.
STREET LIGHTING
No street lighting is required. If the Applicant desires to install a street light, all costs associated
with the installation and maintenance are the responsibility of the Applicant and shall be
coordinated with the Jefferson County PUD#1.
ROAD APPROACHES
The extension of Charles St. off of Kingfisher PI. shall be built off the centerline of the
hammerhead turnaround area constructed under RAP2009-00053. The Charles St. approach to
the platted right-of-way from the private easement shall meet the requirements for a
residential approach (Exhibit D). Approach shall be an integral part of the roadway and
constructed at a location acceptable to the parcel owner(s).
DRAINAGE, EROSION CONTROL, AND STORMWATER MANAGEMENT
The Jefferson County Unified Development Code, Section 18.30.070 Stormwater Management
Standards adopts the standards of the Washington Department of Ecology Stormwater
Management Manual for Western Washington (most current version).
A Stormwater Management Permit is required for projects that exceed 2,000 square feet of
impervious surface or 7,000 square feet of land -disturbing activity. See Exhibit E for comments
from the Department of Community Development. The proponent shall contact the Jefferson
County Department of Community Development to discuss permit requirements and application
procedures:
Jefferson County Department of Community Development
612 Sheridan Street
Port Townsend, WA 98368
(360) 379 - 4450
MAINTENANCE AND NO PROTEST AGREEMENT
A Road & Stormwater Facility Maintenance and No Protest Agreement is required for this
facility on a public right-of-way.
Any privately maintained road and stormwater facility on public right-of-way shall be
maintained at the owners' expense and as outlined in the Road & Stormwater Facility
Maintenance and No Protest Agreement. A No Protest Agreement is required for any privately
maintained road on public right-of-way. The applicant has applied for a permit to construct a
privately -maintained gravel roadway on public right-of-way. The County Engineer has
recommended that this request be approved. It is recognized that this private road does not
meet current County road standards for a public roadway which would require a wider roadway
Page 5 of 7
with an asphalt paved or bituminous surface. In consideration of the County agreeing to waive
the requirements to construct to full public road standards, the Grantor must also enter into an
agreement with the County not to protest the formation of a Road Improvement District (RID)
or other pro rata cost sharing mechanism to improve the roadway in the future should
improvements become necessary whether proposed by petition or by resolution of the Board
of County Commissioners or by both petition and resolution. The Grantor(s) further agree to
join in any proposed petition for such road improvements. See Exhibit F for this Agreement.
GATES
This road will not be maintained at public expense. The Applicant will be required to maintain
the roadway. Installation of gates, barriers, or signs that block the public's use of this right-of-
way after the road is constructed are NOT allowed.
ROADWAY CONSTRUCTION DOCUMENTATION, CERTIFICATION, AND MONUMENTATION
Construction Documentation
The applicant shall provide the Public Works Department with complete road plans in electronic
format to scale on 11x17 inch paper. Since this will be a privately maintained gravel road,
although the road centerline must be established by a licensed surveyor prior to construction,
centerline monumentation is not required. Following completion of roadway construction, the
proponent shall submit to Public Works complete "As -Built" or "As Constructed" record
drawings. The drawings shall reflect any changes made to the original design. The proponent
or designee shall keep detailed records of the as constructed locations of all surface and
subsurface facilities to be included on the record As -Built or As -Constructed drawings.
Construction Certification
Certain items will need to be inspected during construction of these roadways. These
requirements will be identified once complete plans have been submitted to Public Works for
review.
Following completion of roadway construction the proponent shall submit to Public Works a
letter, affixed with the professional stamp of the Engineer of Record, certifying that the
roadway and stormwater management facilities have been constructed in accordance with the
design plans and specifications and all applicable federal, state and local agency requirements.
PERMIT
This report is not a Permit.
After the review and approval of all documents, plans, and/or reports required by this report,
and within three (3) years from the date of Board of County Commissioners approval of this
report, and prior to initiating construction, the applicant shall be issued a permit by the Public
Works Department. This Permit specifically outlines the arrangement between the applicant
and the County for work on public right-of-way by the applicant. The Permit will specify
insurance and bonding requirements, general provisions, and other requirements that are
Page 6 of 7
applicable for work to be performed in County right-of-way. The Permit, once issued, will be
valid for one year from the date it is issued. The road right-of-way will not be considered to be
opened until all conditions of the permit are met and the permit is finalized. A sample copy of a
Permit is attached as Exhibit G.
OTHER PERMITS
Other permits and/or environmental review may be required for this project per Jefferson
County Unified Development Code (UDC). Any questions concerning the necessity of other
permits and/or environmental review and the processes should be directed to the Jefferson
County Department of Community Development, 612 Sheridan Street, Port Townsend, WA
98368, Phone (360) 379-4450.
RECOMMENDATION:
Public Works recommends that this request to open County right-of-way to the standards and
requirements listed above be approved. This recommendation will be forwarded to the
Jefferson County Board of County Commissioners for approval by way of Resolution (Draft
Exhibit H). Once completed, inspected and all permit conditions met, the permit will be put in a
'Final' status and this road will be considered to be opened but will be privately maintained and not
become part of the County road system

Step 2.1
Start HERE! A guide to using stormwater forms
All projects must read and complete the Stormwater Calculation Worksheet.
Use the quantities reported in this worksheet to determine which minimum requirements apply to your project
and what forms will be required using the "Flow Chart for Determining Minimum Requirements."
Small Projects may submit the Worksheet S Small Project Certification sheet. Applicants who are able to sign the
certification may STOP HERE. Submit the Stormwater Calculation Worksheet and Worksheet "S" with your appli-
cation. No additional submittal is necessary.
Medium Projects must complete worksheets Al, 131, and C or equivalent. Large Projects refer to Worksheet L to
determine applicable worksheets are required or if a state -licensed engineer must prepare the submittal.
A Note on Engineered Stormwater Submittal:
-Many applicants complete stormwater submittal forms independently without professional expertise. For example, full
dispersion, if feasible on the site (See Worksheet C), is typically easiest to implement for many different surface types such as
roof, driveway, patio etc.
-Applicants may opt to submit an engineered stormwater plan even if it isn't required. This option may be attractive to those who
are unsure how some of the requirements will be achieved on the site.ln some instances, engineering will be required. Certain
Large projects must be engineered (See Worksheet Q. Gathering information on infiltration feasibility may need an engineer's
expertise. Or, sites with greater than 15% slopes may require applicants hire a geologist to recommend if a drainage method is
appropriate. Discharging directly to a marine water via tightline must be engineered. If you cannot do full dispersion on parcels
larger than 5 acres, engineering is required. In other instances, site constraints will require an engineered design.
-Jefferson County staff may assist by providing and/or explaining Department of Ecology Stormwater Management Manual
Circle one:
The project requires or the applicant elects to submit an engineered stormwater plan. The plan is attached hereto
with minimum requirement narrative, drawings, calculation, modeling output, construction pollution prevention

plan, and site plan.
If you answered YES above, STOP, no further submittal is required. Otherwise, proceed with the following steps.
Step 3
Complete Worksheet Al Medium/Large Project Report and Stormwater Site Plan or equivalent.
Step 3.1
Complete Worksheet C to determine which BMPs are possible and appropriate for your site. Circle the first BMP
that is feasible (i.e. none of the infeasibility criteria is checked) for each surface type. Circle the corresponding
BMP on Worksheet Al.
Step 4
Complete Worksheet B1 Medium/Large Project Construction Pollution Prevention Plan and Worksheet B2
Construction Site Plan or equivalent.
A Note on Commercial Projects:
• Jefferson County Public Works (JCPW) reviews commercial projects and charges a review fee. JCPW may charge additional
fees for any required inspections.
• Any commercial projects proposing infiltration facilities may complete Worksheet E—Infiltration Test. Grain size analysis may
be used instead of PIT. Commercial projects may elect to use BMP T5.10A and would not need a PIT, just a soil evaluation.
• Any development for cottage industries may require a commercial public works review if full dispersion is infeasible.

Land -disturbing activity is any activity that results in movement of earth, or a change in the existing soil cover (both vegetative and
non -vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling,
excavation, and compaction associated with stabilization of structures and road construction.
Native vegetation is vegetation comprised of plant species, other than noxious weeds, which reasonably could have been expected
to naturally occur on the site. Examples include species such as Douglas fir, western hemlock, western red cedar, alder, big -leaf
maple, and vine maple; shrubs such as willow, elderberry, salmonberry, and salal; herbaceous plants such as sword fern, foam
flower, and fireweed.

STORMWATER CALCULATIONS — IMPERVIOUS SURFACE
Impervious surface is a hard surface that either prevents or slows the entry of water into the soil as under natural
conditions prior to development. A hard surface area which causes water to run off the surface in greater
quantities or at an increased rate of flow from the flow present under natural conditions prior to development.
Common impervious surfaces include, but are not limited to roof tops, walkways, patios, driveways, parking lots
or storage areas, concrete or asphalt paving, gravel roads, packed earthen materials, and oiled, macadam or other
surfaces which similarly impede the natural infiltration of stormwater.

CONSTRUCTION STORMWATER POLLUTION PREVENTION
Best Management Practices (BMPs) Fact Sheet
For "small' projects (as determined through the Stormwater Calculation Worksheet), submit Worksheet
"S" Small Project Certification. Additionally, the applicant shall consider the twelve Construction
Stormwater Pollution Prevention elements and implement applicable BMPs. A set of useful BMPs for
typical rural residential construction is attached. There is no additional submittal required as part of the
permit application.
For "medium" and "large" projects, applicants must submit a Construction Stormwater Pollution
Prevention Plan (SWPPP) and a Stormwater Site Plan (applicants may use Worksheet B1 or equivalent).
The following twelve elements must be considered for Construction Stormwater Pollution Prevention
before and during the construction phase of the project:
1. Mark Clearing Limits
7.
Protect Drain Inlets
2. Establish Construction Access
8.
Stabilize Channels and Outlets
3. Control Flow Rates
9.
Control Pollutants
4. Install Sediment Controls
10.
Control De -Watering
5. Stabilize Soils
11.
Maintain Best Management Practices
6. Protect Slopes
12
Manage The Project
Each of the twelve elements is described in more detail below:
1. Mark Clearing Limits
By minimizing the limits of clearing on the site, a builder can minimize stormwater runoff and provide
effective control of pollution.
Establish Construction Access
Much of the sediment that leaves a construction site does so on the wheels of delivery and construction
vehicles that drive off a project site. Construction access must be limited to a single location and a
properly constructed Stabilized Construction Entrance (BMP C105) should be included on the site.
Control Flow Rates
Stormwater that leaves a project site unimpeded may exceed the capacity of the existing stormwater
control facilities downstream and may contain sediment that may be deposited as the velocity of the
runoff decreases. Stormwater protection on a construction site should include measures to control the
flow rate of runoff from the site. This can be done by installing a Sediment Trap (BMP C240) or other
measure that will impede the flow of water off a construction site.
4. Install Sediment Controls
In addition to limiting the rate of stormwater flow off a construction site, measures should be put in place
to treat the runoff and remove sediment. Limiting of the cleared area (Element 1) will assist in this effort,
but there will be exposed soils that may move with the runoff. Suggested BMPs for controlling sediment
include Straw Wattles (BMPC235), Brush Barrier (BMP C231), Gravel Filter Berm (BMP C232), and Silt
Fence (BMP C233). Installation of a Sediment Trap (Element 3) is an additional sediment control feature.
construction Pollution Prevention Page 1 of 3 5/31/2019
Stabilize Soils
An additional measure that can minimize sediment transport in runoff is to stabilize soils on the site with
mulch or some other covering. This will limit the amount of soil that is exposed to rainfall, thus limiting the
sediment that could potentially leave the site. BMPs that could be used for this include Mulching (BMP
C121), Nets and Blankets (BMP C122), and Plastic Covering (BMP C123). During periods of dry weather
dust can become a problem and sediment could be transported from the site in high winds. BMP C140
Dust Control should be followed to limit loss of soils in windy conditions.
6. Protect Slopes
If the cleared area includes slopes of 3:1 (Horizontal: Vertical) or steeper, the slopes should be protected
to limit runoff. If the slopes are not protected, rills and gullies may form, transporting sediment to the
lower elevations and potentially off the construction site. The slopes should be graded to minimize
erosion and runoff at the downstream end of the slopes, and runoff should be collected and treated. The
following BMPs could be used Surface Roughening (BMP C130), Interceptor Dike and Swale (BMP
C200), and Pipe Slope Drains (BMP C204).
7. Protect Drain Inlets
Runoff from urban construction sites often discharges into existing stormwater collection systems. Water
enters the collection system through drain inlets. If there are drain inlets downstream of a construction
site, they should be protected using BMP C220 Storm Drain Inlet Protection.
8. Stabilize Channels and Outlets
Any temporary on -site channels or ditches that are used to control runoff should be stabilized to prevent
erosion in the channel. BMP C202 Channel Lining and BMP C209 Outlet Protection should be used.
Control Pollutants
The best way to control pollution is to limit the source of pollution. Construction debris should be
maintained in a safe location. Vehicle maintenance on the construction site should be minimized and any
spill should be promptly cleaned up. Concrete spillage should be kept to a minimum and cleaning of the
concrete trucks after they have unloaded should be done in an area that will not drain off site (see BMP
C151 Concrete Handling).
10. Control Dewatering
In some cases, excavation for the foundation or below ground structures will encounter ground water.
This water must be removed (dewatered) from the excavation. Discharge of this ground water must be
treated in a manner that will not cause damage downstream due to flow rates or added pollution. There
are no specific BMP identified for this activity, but the water should be handled with care to assure that
soils or other pollutants are not added to this flow.
11. Maintain BMPs
Installation of the appropriate BMPs is not adequate to completely control stormwater runoff. The BMPs
that have been installed on the project must be inspected and maintained during the duration of the
construction project. In addition, the temporary controls that were installed for construction should be
removed within 30 days of completion of the work. Typically, once construction has been completed, the
temporary facilities are not maintained, and by removing the facilities, it will ensure that these won't fail
and discharge water or sediment that had been previously trapped or contained.
12. Manage the Project
Management of a project has four aspects:
1. Phasing construction to prevent transportation of runoff and sediment,
2. Limiting the work during seasons where large amounts of rainfall could be anticipated,
3. Coordination with Utilities and other Contractors, and
4. Inspection and Monitoring.
All of these for aspects are important and must be followed to ensure a project that will have minimal
impact on the environment. Volume II of the Manual contains additional BMPs that could be used on -site.
The applicant is encouraged to review the Manual to see if other BMPs may be applicable to, or more
useful on, a particular site.

Minimum Requirement # 1 : Preparation of Stormwater Site Plan
Complete the following:
Submit a site plan demonstrating the project. Refer to REFERENCE A1A for examples of Best Management
Practices (BMP's) that you can use. Remember that all site plans submitted for the project must be consistent
and accurate.
Describe both existing and proposed site conditions for the following items as applicable in the space below each
bullet point. Attach additional pages if needed.
• structures
• roods
• utility locations
• expected exravatron
Minimum Requirement # 2 : Construction Stormwater Pollution Prevention Plan (SWPPP)
A SWPPP is designed to be a stand-alone document that addresses construction stormwater management concerns. This
document is required to be kept by the contractor performing the work at the jobsite for reference and update during
the life of the project. Construction BMP's must be indicated on the stormwater site plan. REFERENCE 131A includes
diagrams of common BMP's that may be used on the site plan.
❑ My completed SWPPP (WORKSHEET 131 or equivalent) is included in this application packet!
Minimum Requirement # 3 : Source Control of Pollution (not construction related)
The intent of source control is to prevent stormwater from coming in contact with pollutants. Source control BMPs
can be operational or structural in nature. A roof over a material storage area is an example of a structural source
control BMP. Washing your vehicle on the lawn rather than in the street is an operational BMP. This requirement
is generally not applicable to Single Family Residences (SFRs); however, ways to minimize pollution from moving
downstream should be considered during the design phase of every project. Specifications on standard source control
BMPs that are applicable to various commercial and industrial -type facilities can be found in Volume IV of the 2014
Stormwater Management Manual for Western Washington (SWMMWW) (continued on page 2).

Minimum Requirement # 4 : Preservation of Natural Drainage Systems
Creating new drainage patterns results in more site disturbance and more potential for erosion and sedimentation during
and after construction. to the maximum extent possible, proponents must 1) maintain the natural on -site drainage
pattern and concentrated discharge location at the downstream property boundary, and 2) prevent erosion at and
downstream of the discharge location.
NOTE: All outfalls require energy dissipation. See Table 4.5.1 in Vol. V of the SWMMWW for minimum design standards
for rock protection at outfalls.
Choose the option below that best describes your project:
The project site does not currently have any intermittent, seasonal, or continuous concentrated water
moving across any part of the property and the proposed improvements to the site will not create new
concentrated flow paths or not discharging to existing drainage systems.
❑ The project site has existing concentrated flow drainage systems and outfalls. (NOTE: These items must
be graphically shown on the Site Plan or equivalent, to include: type, slope, dimensions, channel lining,
direction of flow, buffer, etc.) Select below how it will be addressed.
This project will not alter the existing drainage system in any way. If the existing outfall(s) show
signs of erosion and scour, energy dissipation measures will be installed or improved upon.
Construction activity of any kind will not occur within at least 10 ft. of the edge of the channelized
flow. BMP C102: BUFFER ZONES will be implemented during the life of the project to include visible

Medium & Large Project Report
Minimum Requirement # 5 : On -site Stormwater Management
On -site stormwater management techniques shall be implemented where possible to accommodate the permanently
added stormwater runoff being generated by development. Some on -site stormwater management techniques provide
better stormwater detention and treatment than others; however, they are not always appropriate for use due to varying
individual site characteristics. Therefore, techniques are presented to applicants on the next pages in a hierarchical order
and shall be considered for use in the order listed. The first technique on the list that is determined to be possible shall
be implemented. See WORKSHEET C to determine which techniques are feasible.
Runoff from developments occurring in drainage basins that drain directly or indirectly to a creek require a higher level
of stormwater management, thus, the techniques are presented in three lists below:
All properties will be in one of these three categories:
My project is located in a drainage subbasin that My Project will discharge to a subasin draining to
drains to directly or indirectly to freshwater. salt water, Dosewallips River, or Hoh River.

RE: Open Right -of -Way Application
Platted Charles St.
Applicant —Shawn Behrenfeld
Assessor Parcel Numbers: 962700023 & 901132001
Dear Terry,
RECEIVED
MAR 14 2022
Je}arson County Fublic Works
We appreciate the opportunity to provide comments on Mr. Behrenfeld's request to open the Charles Street
right-of-way. Here are our concerns:
The request is for a non -adjacent CF-80 - Commercial Forest parcel (901132002). It doesn't make
sense to route commercial forest traffic through the middle of over 1.2 miles of residential
neighborhood, on a hill with four 90-degree turns, when there are other closer, safer options the
requestor could pursue (e.g. requesting from Pope Resources the use of their already -constructed
access roads - they share approximately 1500 feet of property line; or a connection to Elkins Rd, which
is already used by large trucks with heavy loads; or Beaver Valley Rd...).
The residential neighborhood that the requestor seeks to traverse has only one public access point. As
such, we feel that it would be unsafe to route further traffic, esp. forestry machinery and logging
trucks, through the neighborhood. There is no sidewalk or shoulder, so pedestrians walk on the road.
Also, in the event of an emergency, there is only one way for everyone to get out of the neighborhood,
or for emergency vehicles to get in.
® Based on Case # PRE2021-00036, the requestor would also like to route traffic to/from 9 residential
lots across his commercial forest parcel etc., to the same single access point noted above. Again, more
traffic increases the risks to the affected neighborhood.
0 Does the fire marshal or any other emergency services personnel provide input to this request?
m Opening the "request area" would facilitate access to a public dead end in the woods at the
intersection of parcels 962700023, 901131001 and 901132001, which is not a benefit to the public or
the residents of the affected neighborhood. Would the "request area" be included in the Sheriff
Department's regular patrol route?
The "request area" connects to the affected neighborhood at a right angle at the end of Kingfisher
Place. Approximately 600' of Kingfisher Place is a narrow one -lane gravel road that's on county -owned
land but is privately maintained by the adjacent residential parcels with RAPS. The other
approximately 1200' of Kingfisher Place is unmarked paved road maintained by the county. What
happens with the privately -maintained portion of Kingfisher Place if the "request area" is opened?

Additional information related to the previous comments is below, and a notated map is attached for
reference.
Additional information:
CF-80 parcel 901132002 is in a different Planning Area, Subdivision and Neighborhood than the
affected residential neighborhood.
The affected neighborhood's only public access point is at the intersection of Jacobsen Drive and Oak
Bay Road.
The July 4, 2009 easement agreement from parcel 901132002 along the south end of 901132001 to
the unopened Charles Street did not exist when the current owners of Kingfisher Place parcels
96270023, 96270022 and 96270024 purchased those lots. The easement appears to be based on an
agreement between 2 parcel owners (Chimacum Heights LLC & Port Hadlock Family Partnership)
rather than part of the county's development vision or plans, and it changes the ramifications of
opening the Charles Street "request area."
• Mr. Behrenfeld's "Queen Anne" block of nine RR-20 parcels on the northwest side of 901132002 has
had a non-exclusive ingress, egress and utilities easement with an adjacent parcel — 901114001— since
at least 1981, and it was revised in 2013.
• The properties adjacent to the "request area" are already accessed other ways:
o Commercial Forest parcel 901131001 - Pope Resources accesses their property from the south.
o RR-20 - Rural Residential parcel 962700023 is accessed at 323 Kingfisher Place.
o RR-20 - Rural Residential parcel 901132001 is accessed at the west end of Kingfisher Place.
Thank you for considering these comments with your analysis.
Sincerely,
,9"Wq)X90d
