TRANSPORTATION IMPACT STUDY REQUIREMENTS
The preparer of the transportation impact study shall contact the Public Works Director to
discuss study area limits (including the number of intersections to be analyzed,and key project
issues)for their specific project prior to beginning the study.The preparing engineer is
responsible to define key study variables with the City prior to completing work.A site plan
indicating proposed access locations,development size,number of parking stalls and on-site
circulation must be provided by the developer before beginning the transportation impact study.
The transportation impact report shall be prepared under the supervision of a Registered Civil
Engineer in the State of Washington with a traffic engineering background.Studies that do not
address the guidelines adequately shall be returned to the engineer for modification.The
attached checklist will be used for review by City Staff in accepting transportation studies for
public review.
I
;
Peak hour traffic counts will be conducted at study area intersections.Intersections of arterials
or collectors should be considered in determining study intersections (use of AM,mid-day,PM
or weekend peak hour will depend on proposed use1.Existing traffic counts may be utilized
provided they were conducted within the previous 12 months.A 24-hour traffic count and speed
survey will be conducted near proposed project site points.If two project access points are
located on the same roadway,and are within 2,000 feet,then one ADT/speed survey on the
subject roadway will be required.Accident data at all study area intersections covering the most
current three years should be obtained 2 and summarized in table format in the final report.
u
The following is a list of the minimum information required when conducting a transportation
impact study in the City of Camas:
Executive Study with recap of the following:
A project description including site location map and characteristics as well as all
existing and proposed land uses for the site.
A study area description including description of roadway (roadway classification,
posted speed,ADT volumes,number of lanes,traffic control,width of road,pedestrian/
bicycle facilities),transit stops and service,parking conditions,existing geometric
deficiencies,accident data at study area intersections ,and other pertinent features.
1.
2.
1 For example,residential and employment uses (office,warehouse,manufacturing and industrial)will consider MA
and PM periods,schools will consider AM and afternoon periods,retail will consider PM and mid-day (for retail
projects over 70,000 sf -access issues of driveway turn land storage for site and adjacent intersections will be
reviewed on Saturdays.As a minimum,the analysis shall analyze the period of greatest traffic for adjacent study
intersections and determine the period of greatest trip generation for the project.
2 Accident data shall be obtained from WSDOT,Traffic Office,SW Regional Traffic Engineer.
3 An average of 2 accidents per year over the most recent 3 years at a particular intersection shall mandate further
study of the intersection.

!Land Use Review Process Guidelines
Including Neighborhood Traffic Management
City of Camas
The most opportune time to address neighborhood needs is at the point of development (when
the streets are built).Whether it is a residential subdivision,commercial development or a
transportation project,incorporating of Neighborhood Traffic Management1 (NTM)elements
into the design,development,and mitigation of the off-site impacts of a project assures that the
inventory of neighborhood problems does not grow.To best address this through policy,a two
tiered approach is recommended.The first tier is aimed at new residential development planning
and the second tier is focused on mitigating impacts of new land use or transportation
development .If in either case it is desired to consider a NTM measure that is not part of the tool
box,the applicant (using a registered professional engineer)will be required to provide and
certify the appropriate performance and design standards.
Tier 1 :Design of New Residential Street System.Any new streets built with development
should incorporate NTM in design.An additional level of analysis should be added into the
Traffic Impact Analysis guidelines for proposed projects.A map should be prepared that
identifies all nearby streets (especially category “C”streets)that the proposed land use action
may create or impact.On all projects,any internal street reaching the threshold of 700 vehicles
per day will enter the NTM process at Step 6 and demonstrate how speed and volume will be
kept at 25 mile per hour to the satisfaction of the Department of Public Works prior to approval.
In project review,this criteria will be evaluated and if adequate measures are not identified,staff
can request that the site plan be modified to reflect the future neighborhood needs for NTM
measures.
I
>
Tier 2:Mitigating the Impact of New Development.All new major land developments will
be required to provide information in their Traffic Impact Analysis (TLA)that identifies the
potential impact on neighborhoods or local streets.This goes beyond the capacity analysis that is
conducted presently.A section would be added to the TLA that assesses the impact of a land use
or transportation project on neighborhood routes or local streets (all nearby category “C”streets).
The TLA should identify if the project adds more than 25 vehicles per hour (two way -AM,PM
and/or retail peak hours)to a sheet and the street volume is projected to be larger than 700
vehicles per day.An estimate will be made of the potential (in the future at build-out of nearby
lands)for a neighborhood or local street to exceed 700 vehicles per day.Determination of
potential streets for consideration for each project should be reviewed with city staff prior to
submitting the TLA.

Other Issues :
:During the development of the NTM plan,the issue of photo enforcement or automated
enforcement was raised.These measures have been used in communities (Vancouver,Portland,
and Beaverton are examples)to address speeding in neighborhood areas and school zones.
Elsewhere in the United States,automated enforcement is being used to address red light running
of traffic signals and violating at-grade railroad crossing controls.In Europe,the use of the
speed-reader board trailers has developed into permanent speed reader signs in critical locations.
These measures would need legislative action for implementation in Camas and may be
considered in the future to be included in the NTM Tool Box should the necessary legislative
issues be adequately address such that judges will support its appropriate use.

“Adjacent”means an area within one hundred (100)feet of a geologic hazard.Or
where the geologic hazard could impact.
“Buffer”means an area adjacent to hillsides which provides the margin of safety
through protection of slope stability,attenuation of surface water flows and
landslide ,seismic,and erosion hazards reasonably necessary to minimize risk to
the public from loss of life,well-being or property damage resulting from natural
disasters;or 2)an area adjacent to a stream or wetland which is an integral part
of the stream or wetland ecosystem,providing shade;input of organic debris and
coarse sediments;room for variation in stream or wetland boundaries;habitat for
wildlife;impeding the volume and rate of runoff;reducing the amount of
sediment,nutrients,and toxic materials entering the stream or wetland;and
protection form harmful intrusion to protect the public from losses suffered when
the functions and values of stream and wetland resources are degraded.
"Development activity"means any construction,development,earth movement,
clearing,or other site disturbance which requires a permit,approval or
authorization from the county.
"Director"means the director of the department of public works or that person's
designee.
"Geologic hazard areas"means areas having steep slopes;potential,active or
previous landslides;or extreme seismic hazard that are defined and regulated by
this chapter.
"Engineering Geologist"means a person who is a registered professional
Engineering Geologist in the State of Washington,and has demonstrated
expertise in designating and mitigating geologic hazards.
"Geotechnical engineer"means a professional engineer licensed in the state of
Washington with expertise in geotechnical engineering.
"Landslide"means down-slope movement of a mass of soil,or rock,including,
but not limited to,rock falls,slumps,mud flows,debris flows,torrents,and earth
flows.
"Landslide hazard areas"means areas that,due to a combination of slope
inclination,soil type and presence of water are susceptible to landsliding in
accordance with the following criteria:
(a)Areas of previous slope failures including areas of unstable old or recent
landslides;
(b)Areas with all three (3)of the following characteristics:
(i)Slopes steeper than fifteen percent (15%),
(ii)Hillsides intersecting geologic contacts with permeable sediment overlying a

"Slope"means an inclined ground surface,the inclination of which is expressed
as a percent ratio of vertical distance to horizontal distance (v/h).
“Steep slopes or area with potential unstable soils”means any land potentially
subject to landslides,severe erosion or seismic activity (earthquake faults).
Steep slopes are generally characterized by slopes of 15%or greater,
impermeable subsurface material (sometimes interbedded with permeable
subsurface material),and/or springs or seeping groundwater during the wet
season.Seismic areas are those lying along or adjacent to identified
earthquakes faults.
"Steep slope hazard area"means an area where there is not a mapped or
designated landslide hazard,but there are steep slopes equal to or greater than
forty percent (40%)slope.Steep slopes which are less than ten (10)feet in
vertical height and not part of a larger steep slope system,and steep slopes
created through previous legal grading activity are not regulated steep slope
hazard areas.The presence of steep slope suggests that slope stability problems
are possible.
"Subject property"means the entire lot or parcel,or contiguous combination
thereof,on which a development activity is proposed.

Submittal requirements.
:
For development activity,submittal requirements will vary depending on the type
of project and the type of hazard mitigations that are proposed.A review of a
geologic hazard area will be conducted in conjunction with the primary
development application.All Projects are required to submit a basic site
description sufficient^verify that the location of proposed building and access
road improvements comply with buffers,setbacks,and vegetation preservation
requirements.If a regulated activity is proposed within an area with steep slopes
or area with potentially unstable soils additional information in the form of a
geologic hazard area study must be provided.:
Basic site description
The director may waive parts of the submittal requirements if the department
determines that they are not applicable to the proposed activity.The director may
also require additional information based on the submittal to provide a through
review.As part of the development permit application,the fol owing information
describing the subject property is required.

EROSION/SEDIMENT CONTROL NOTES:
1.THE EROSION/SEDIMENT CONTROL (ESC)PLAN IS TO BE UTILIZED AS A GUIDE TO
CONTROL THE TRANSPORT OF LOOSE SOILS TO THE PROPERTY OUTSIDE OF THE
CONSTRUCTION AREA AND AROUND THE CONSTRUCTION SITE.THE ESC
MEASURES SHALL BE UPGRADED AS NEEDED FOR UNEXPECTED STORM EVENTS
AND TO ENSURE THAT SEDIMENT AND SEDIMENT LADEN WATER DOES NOT LEAVE
THE SITE.
2.THE IMPLEMENTATION OF THE ESC PLANS AND THE CONSTRUCTION,
MAINTENANCE,REPLACEMENT AND UPGRADING OF THE ESC MEASURES IS THE
RESPONSIBILITY OF THE CONTRACTOR UNTIL ALL CONSTRUCTION IS COMPLETED
AND APPROVED AND PERMANENT VEGETATION/LANDSCAPING IS ESTABLISHED.
3.IF THE CITY INSPECTOR OR ENGINEER(S)HAS EVIDENCE OF POOR CONSTRUCTION
PRACTICES OR EROSION CONTROL TECHNIQUES,A “STOP WORK”ORDER SHALL BE
ISSUED UNTIL PROPER MEASURES HAVE BEEN TAKEN AND APPROVED BY THE CITY
ENGINEERING STAFF.
4.THE CONTRACTORS SHALL BE RESPONSIBLE TO FAMILIARIZE THEMSELVES WITH
THE CITY OF CAMAS EROSION/SEDIMENT CONTROL HANDBOOK AND THE
STORMWATER MANUAL IN WASHINGTON STATE (LATEST EDITION),VOL.II.
5.ALL EROSION/SEDIMENT CONTROL MEASURES SHALL BE IN PLACE AND IN WORKING
CONDITION PRIOR TO DISTURBING AND EXPOSING ANY SOIL SURFACES (I.E.
CONSTRUCTION ENTRANCES,FILTER FABRIC /STRAWBALE SEDIMENT BARRIERS,
AND SEDIMENTATION TRAPS)AND MAINTAINED FOR THE DURATION OF THE
PROJECT.TRAPPED SEDIMENT IN EXCESS OF 1 FOOT SHALL BE REMOVED OR
STABILIZED ON-SITE.DISTURBED SOIL AREAS RESULTING FROM VEGETATION
REMOVAL SHALL BE PERMANENTLY STABILIZED.ADDITIONAL MEASURES MAY BE
REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT CLEAN FOR THE
DURATION OF THE PROJECT.
6.TO MINIMIZE EROSION AND SEDIMENTATION TRANSPORTATION,EARTHWORK
SHALL NOT BE PERFORMED WHILE SOILS ARE IN AN UNSTABLE STATE DUE TO
PRECIPITATION.
7.THE CONTRACTOR SHALL BE RESPONSIBLE TO HAVE CLEARING LIMITS AND /OR ANY
EASEMENTS,SENSITIVE OR CRITICAL AREAS,AND THEIR BUFFERS,TREES,AND
DRAINAGE COURSES FLAGGED PRIOR TO CONSTRUCTION.DURING THE
CONSTRUCTION PERIOD,NO DISTURBANCE BEYOND THE FLAGGED CLEARING
LIMITS SHALL BE PERMITTED .FLAGGING LIMITS ARE TO BE MAINTAINED BY THE
CONTRACTOR FOR THE DURATION OF CONSTRUCTION.
8 .REMOVE ONLY THOSE TREES AND SHRUBS THAT NEED TO BE REMOVED FOR THE
CONSTRUCTION OF ROADS,SIDEWALKS,UTILITIES,AND STORMWATER FACILITIES.
9.ALL ROAD EXISTING AND NEWLY CONSTRUCTED CATCH BASINS OR CURB INLETS
AFFECTED BY CONSTRUCTION SHALL BE PROTECTED AGAINST SEDIMENT
DEPOSITS.AT NO TIME SHALL MORE THAN ONE FOOT OF SEDIMENT BE ALLOWED
TO ACCUMULATE WITHIN A TRAPPED CATCH BASIN.ALL CATCH BASINS AND
CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING.THE CLEANING
OPERATION SHALL NOT FLUSH SEDIMENT LADEN WATER INTO THE DOWNSTREAM
SYSTEM .
10 .ALL POLLUTANTS THAT OCCUR ON-SITE DURING CONSTRUCTION SHALL BE
HANDLED AND DISPOSED OF IN A MANNER THAT DOES NOT CAUSE CONTAMINATION
OF STORMWATER SYSTEM .
11.ALL DISTURBED SOIL SURFACES ARE TO BE STABILIZED BY A SUITABLE
APPLICATION OF “BEST MANAGEMENT PRACTICES”.NO SOILS SHALL REMAIN
UNSTABILIZED FOR MORE THAN TWO DAYS DURING THE PERIOD OF OCTOBER 1
