These requirements are intended to supplement the general requirements of the Spokane Valley Municipal Code (SVMC) Chapter 22.130, and are adopted pursuant to SVMC 22.130.040. Required improvements and dedications shall be in compliance with all Chapters in these Street Standards. An overview of the review process for this Division can be found in the "Development Engineering Guidelines"which are adopted herein by reference. 2.2 APPLICABILITY Projects reviewed and conditioned by Development Engineering fall within three general categories: • Land divisions (short subdivisions, subdivisions and binding site plans); • Commercial building permits; and, • Miscellaneous projects which include access permits, boundary line adjustments, rezones, changes of use, changes of occupancy, temporary use permits and conditional use permits. In some instances, this last category of projects may not need a building permit. They may, however, result in an increase in traffic and other impacts that can require street improvements and other mitigation. 2.3 REQUIRED DEDICATIONS AND IMPROVEMENTS This section describes the dedications and types of improvements that may be required pursuant to the SVMC Chapter 22.130, the Revised Code of Washington (RCW) chapters 35.63.080, RCW 35.63.090, RCW 35A.63.100, RCW 43.21C; RCW 58.17, and RCW 82.02.020. Land divisions and development permits trigger requirements for dedications of public right-of-way, border easements, future acquisition areas, and other improvements. Other project types may also trigger these requirements. Specific requirements shall be determined during project review. To determine the requirements for a project, the City considers the following: a. Existing improvements both onsite and offsite, such as curb, gutter, swale and sidewalk; b. Any anticipated increase in traffic that would lead or contribute to an unacceptable level of service; c. Connectivity of existing or future streets to better serve public and emergency vehicle mobility; Adopted December 2009 Chapter 2—Development Engineering Requirements 2-1 CITY OF SPOKANE VALLEY STREET STANDARDS d. Street classification, as shown in the City's Comprehensive Plan; e. City of Spokane Valley 6-year Transportation Improvement Program and any anticipated improvements in the project vicinity; f. Public safety as affected by the project (i.e. pedestrian and vehicle safety, traffic flow, etc); g. Bike routes, as shown in the City's Comprehensive Plan; and, h.

Width of Patch: For this document the width of all patches is the patch dimension perpendicular to the roadway. Assignee: The contractor who is taking out the permit. Patch: Cut in the pavement as part of the current permitted job. Potholing: Potholing is the practice of digging a test hole to expose underground utilities to ascertain the horizontal and vertical location of the facility.The horizontal and vertical position of the exposed facility must be tied to a survey benchmark or permanent above grade feature.The position may be identified by GPS or traditional survey coordinates or by measuring the distance, with a tape measure,to permanent features in three horizontal directions.In addition,the vertical distance below grade should be obtained. Bell Hole:A hole dug to allow room for workmen to make a repair or connection in buried pipe, such as caulking bell-and-spigot pipe or welding steel pipe.A bell hole can also be used for the starting location of an underground bore,when using the directional boring equipment.In the broad sense, any hole other than a continuous trench opened for working on a buried facility Compaction: Restoration and backfill of the Trench,Pothole, and Bell hole. Each shall be compacted in lifts using the industry standard equipment to tamp the backfill material to 95% density. Tier:Age of asphalt Full depth:Asphalt depth top to base of asphalt or thickness of asphalt Gap: Distance between two asphalt patches Keyhole:New technology for core drilling;used to drill a plug in the asphalt when checking the depth of existing utilities. MUTCD:Manual on Uniform Traffic Control Devices: Traffic Control should be set up to warn and protect the workers and general public by avoiding the working area during construction. Traffic Control must meet or exceed the Washington State modifications to the MUTCD code for all work done with the City Right of Way(see http://mutcd.fnwa.dot.gov section, Chapter 6G and 6H).

Some street designs require technical criteria that are above the scope of this manual and therefore not covered. In these cases, design manuals from the above referenced agencies and references listed in Section 1.11 should be used for a basis of design. The standard plans referenced in this chapter can be found in Chapter 11. 7.2 TERRAIN TYPES Terrain type can be classified as flat, rolling or mountainous. Flat terrain is the condition where roadway sight distances, as governed by both horizontal and vertical restrictions, are generally long or could be made to be so without construction difficulty or major expense. The slope of the existing terrain is from 0 percent to and including 5 percent. Rolling terrain is that condition where the natural slope rises above and falls below street grade line consistently. Normal street alignment is restricted some by occasional steep slopes. The slope of the existing terrain is from 5 percent to and including 15 percent. Mountainous terrain is that condition where longitudinal and transverse changes in the elevation of the ground with respect to a street are abrupt and where the roadbed is obtained by frequent benching or side hill excavation. The slope of the existing terrain exceeds 15 percent. 7.3 STREET TYPES Streets within the City include public and private streets. Since community needs are usually best served by streets owned and maintained by the City, most projects are required to be accessed via public streets. Private streets may be appropriate for some local accesses in very limited usage. For the purposes of these Street Standards, the following sections provide additional descriptions of streets. 7.3.1 PUBLIC STREETS Public streets are owned and maintained by the City. All public streets in the City have been classified using the Federal Functional Classification system, which provides a hierarchy, from principal arterials to local access streets, to accommodate existing and anticipated traffic. Street classifications can be found in the City of Spokane Valley Comprehensive Plan. Adopted December 2009 Chapter 7—Street Elements 7-1 CITY OF SPOKANE VALLEY STREET STANDARDS Public streets can be triggered by land actions or development permits as described in Chapter 2. Public streets shall be used to connect two public streets and shall be per Standard Plans R-120 through R-122. Sections 7.3 through 7.7, including Tables 7.1 through 7.3, provide design criteria and requirements for public streets. 7.3.2 PRIVATE STREETS Private streets are local access streets, privately owned and maintained. All new private streets shall be approved by the City. Private streets are permitted when all of the following apply: a. Where connectivity to the public street system is not compromised, b. Where future through connection to public streets is not possible, c. The private street does not land lock present or planned parcels, d. The private street serves from two to nine single family dwelling lots, e. The private street provides direct access to a public street. Access to and from private streets shall be limited to properties immediately adjacent to the private street, and f. The private street is not used to connect two public streets. Private streets shall be designed per Table 7.3. The design of a private street shall discourage any through traffic of non- residents. Traffic calming measures may be utilized in the design of private streets. Private streets shall connect to City streets using a standard driveway approach per Standard Plan R-115. A capable, legally responsible owner or homeowners association shall be established to maintain private streets and associated drainage facilities in perpetuity. A plat or short plat with private streets shall be required to provide an executed recorded Private Street Maintenance Agreement and a Stormwater Easement and Maintenance Agreement that obligate future property owners to maintain the infrastructure in perpetuity (see Chapter 10 for requirements). 7.3.3 ALLEYS Alleys are not typically required. However, certain projects may have the option or may be required to provide alley access by the City's Comprehensive Plan or by an adopted subarea plan. Design of alleys typically follows the criteria for local streets (Standard Plan R- 125). The following is a list of design standards that differ from local street elements: a. Alleys shall have a minimum width of 20 feet of asphalt pavement. if the alley is the only access point to the site, the alley width shall meet the width requirements for local access streets (See Table 7.3); Adopted December 2009 Chapter 7—Street Elements 7-2 CITY OF SPOKANE VALLEY STREET STANDARDS b. Curb, gutter and sidewalk are not required, unless conditioned otherwise; and, c. The pavement area may have an inverted crown at centerline to convey stormwater into catch basins located at low points in the invert. Alleys shall connect to a private or public street at each end. In cases where this is not feasible, adequate turnarounds shall be provided. Alleys can be located in the public right-of-way or a private easement. 7.3.4 PRIVATE DRIVEWAYS Private driveways provide vehicular access to one lot. Private driveways shall comply with the following: a. Private driveways longer than 75 feet but less than 150 feet in length shall meet the requirements for width, grade and signing as private streets (See Table 7.3); b. Private driveways longer than 150 feet shall be engineered and meet the requirements for width, grade, and signing as private streets (See Table 7.3); c. Private driveways longer than 750 feet shall only be allowed when approved by the Fire Department. Structures accessed by a private driveway and which are not visible from the public street shall post an address at the street. Addresses shall be permanent by nature and the numbers shall be a minimum of 4 inches tall, 1/2 inch stroke, and contrasting color to the background. Driveways shall not extend off the end of an arm of the hammerhead turn-around. 7.4 HALF-STREET IMPROVEMENTS A half-street is required as an interim facility. Half-street improvements are required for a property fronting a public street that is not currently built to City standards. Half-street construction may also be required for property that abuts future streets proposed in the City's Arterial or Local Street Plan. When half-street improvements are required, the design of the half-street shall be consistent with the existing street classification or as dictated by the City's 6-year Transportation Improvement Plan (TIP) or City Street Plans. This requires construction of more than half the street for safety and drainage reasons. Construction in these circumstances requires a minimum of one travel lane on the opposite side of the roadway and frontage improvements on the project side of the street. Dedication of additional right-of-way and border easements are required, unless the existing right-of-way and easement widths are sufficient to fit the improvements. When half-street improvements are required, a minimum of 28 feet of pavement is required. Street improvements shall be designed to provide drainage for the constructed Adopted December 2009 Chapter 7—Street Elements 7-3 CITY OF SPOKANE VALLEY STREET STANDARDS portion of the street. Provisions shall be made to allow for extension of the storm drainage system to the undeveloped portion of the street for future construction. Transition tapers are required when the new edges of pavement do not match the existing edge of pavement. Tapers are required to conform to Chapter 6 of MUTCD, latest edition. All proposed utilities located within the half-street shall be installed during construction. The unfinished side of the half-street shall be finished with a gravel shoulder, grassed ditch and/or side slope to assure proper drainage, bank stability, and pedestrian and traffic safety (see Standard Plan R-119). When half-streets connect to an intersection, the intersection shall be designed and constructed for the full build-out of the street. The intersection design and construction shall extend for at least 75 feet from the street intersection (SI). 7.5 STREET GEOMETRY Factors contributing to the geometric conditions of a street are discussed in the following sections. All public streets in a subdivision, including half-streets, shall be fully constructed to the plat boundaries. Pavement, gutter, curb and sidewalk shall be extended to allow future connections to occur. 7.5.1 DESIGN CRITERIA Minimum and maximum geometric design elements are provided in Tables 7.1 through 7.3. Any revision to a geometric element or traffic control on a State Highway requires WSDOT approval.

"No Parking"signs shall be posted on side of the street. 7. A minimum 10-foot maintenance and utility easement shall be provided on each side of the private street. 8. Asphalt width based on the length of the street: up to 500 feet= 20 feet; up to 600 feet = 26 feet. The minimum width is 26 feet if there is a fire hydrant on the private street,regardless of street length. 9. Streets 20 to 26 feet wide shall be posted on both sides as a fire lane and with No Parking signs. Pavement widths greater than 26 shall be posted on side of the street as a fire lane and with No Parking signs. If curb is provided,the curb to curb width can be used to determine if a"No Parking"sign is required. 10. If the alley is the only access point to the site, the alley width is 30 feet unless the ADT is less than 200, then the width is 28 ft. Adopted December 2009 Chapter 7—Street Elements 7-7 CITY OF SPOKANE VALLEY STREET STANDARDS 7.5.2 RIGHT-OF-WAY The public street right-of-way shall extend at a minimum to 2 feet behind the curb for projects with separated sidewalk. When the sidewalk is adjacent to the curb, the right-of-way shall extend 2 feet behind the sidewalk. Right-of-way requirements may vary within a street corridor. The required right-of-way width depends on the required street elements, including number of lanes, on-street parking, bike lanes, medians, turn lanes, roadside swales, pedestrian buffer strips and above and below ground utilities. Right-of-way shall be conveyed to the City on a recorded plat or by a right-of-way dedication. 7.5.3 BORDER EASEMENT Border easements shall be granted to the City on a recorded plat or by a recorded easement. Border easements shall extend from the right-of-way line to the back of sidewalk or the back of public facilities when located behind the sidewalk, whichever is the greatest. The border easement shall run the total length of the street on both sides. Fences shall not be constructed inside the border easement. The border easement area shall be kept clear of other objects that would obstruct a driver's view. The sidewalk shall be open for use of pedestrian traffic at all times. The border easements may be used by the utility companies. Utility and other easements can cross the border easement but cannot be entirely located within the border easement. 7.5.4 GRADE Minimum longitudinal grade shall be 0.5 percent for streets with concrete gutters. The minimum longitudinal grade shall be 0.8 percent for streets with asphalt gutters. Maximum allowable grade shall be per Tables 7.1 and 7.3. 7.5.5 CROSS SLOPE All new streets shall be constructed with a center crown, with the cross slope per Tables 7.1 and 7.3. When widening an existing street, the cross slope may range between 2 and 4.5 percent. The cross slope of the higher priority street shall be extended through the intersection. The grade of the cross street shall be adjusted to meet the cross slope of the higher priority street. When two streets with the same classification meet, the street with the higher average daily trip (ADT) shall be selected to act as the higher priority street. The slope of the other street shall be adjusted as required above. 7.5.6 HORIZONTAL CURVES Curve radii shall be as large as possible; the minimum radii shall be used only where necessary. The minimum allowable centerline radii for horizontal curves shall be per Tables 7.1 and 7.3. Angle points are not allowed. All changes in direction shall be made using horizontal curves. Adopted December 2009 Chapter 7—Street Elements 7-8 CITY OF SPOKANE VALLEY STREET STANDARDS Reverse and compound curves should only be used when a single radius curve will not work. For driver safety, compound curves shall have a ratio no greater than 1.5 where the value of the larger radius is divided by the smaller radius. Whenever two streets intersect, a tangent length (measured from the nearest gutter flowline of the intersected street to the point of curvature in the intersecting street) shall be provided for a safe sight distance and traffic operation. The angle of departure from perpendicular shall not exceed 15 degrees for the length of the tangent. The minimum required tangent length shall be per Tables 7.1 and 7.3. For driver safety, horizontal curves shall not begin near the top of a crest vertical curve or the bottom of a sag vertical curve. Connection with existing streets shall be made to match the existing alignment grade of the existing improvements. The centerline, flowline, and existing ground lines of all streets (except cul-de-sacs) shall be continued for 100 feet beyond the proposed construction. 7.5.7 VERTICAL CURVES The minimum vertical curve length for public and private local access streets is 50 feet and 100 feet for arterials. A vertical curve is required when the grade break is 1 percent or greater. The following guidelines shall be followed when designing a profile: a. The grade line shall be smooth flowing; b. The roller coaster type profile should be avoided; c. A broken-back grade line (successive vertical curves in the same direction) generally shall be avoided; d. The grade through intersections on streets shall not exceed 6 percent; e. A sag vertical or flat grade is desirable in advance of such features as channelization and ramp takeoffs in order to provide good visibility; f. The approach at street intersections shall be per Table 7.4; g. When superelevation is allowed, transitions shall be designed per the latest version of the WSDOT Design Manual or AASHTO Policy on Geometric Design of Highways and Streets. The pivot point should be located at the centerline. The gutter profile along the grade break shall be evaluated for stormwater conveyance. Vertical curves and grades created by and along the transition shall conform to these standards; and, h. Vertical curves should be avoided at the intersection with streets or approaches. 7.5.8 STREET SURFACING REQUIREMENTS All travelways shall be paved, including public and private streets, alleys, and private driveways. Paving requirements are specified in Chapter 8. Adopted December 2009 Chapter 7—Street Elements 7-9 CITY OF SPOKANE VALLEY STREET STANDARDS 7.5.9 CURB AND GUTTER Type B curb and gutter shall be used for all public streets per Standard Plan R- 102. When the existing curb is not continuous along the street frontage, the Applicant shall construct curb and/or gutter to provide continuity. 7.5.10 LANDSCAPE STRIP AND SWALES A grass strip shall be provided between the curb and the sidewalk for all public streets, providing a buffer for pedestrians. The width of the grass strip shall be as follows: a. Seven feet wide if the grass strip is not used for drainage. In this case, drainage facilities shall be located in a separate tract. Commercial and industrial projects may place drainage facilities within a drainage easement granted to the City; or, b. Ten feet wide if a continuous roadside swale is provided within the strip. Planting shall conform to Section 7.8.9 of the Spokane Regional Stormwater Manual and Title 22 of the SVMC. Drainage facilities receiving stormwater from public streets shall be located within the right-of-way, within a border easement parallel to the street or within a drainage tract. Drainage facilities receiving stormwater from private streets or engineered driveways shall be located within a drainage easement parallel to the street or a drainage tract. 7.5.11 TURNAROUNDS Streets shall be planned, designed and constructed to connect to future developments. Dead-end public and private streets shall not be more than 600 feet in length. All dead-end streets shall have a turnaround that meets the City and Fire Department requirements. A turnaround is required when: a. The length is 150 feet or more for all types of travelways. The length is measured from the street intersection (SI) to the terminus of the travelway; or, b. A public street is longer than the depth of one lot. Existing stub-end streets greater than 600 feet in length shall be linked to other streets, unless it can be demonstrated that such connections would lead to a substantial rerouting of through traffic onto the street. Non-motorized paths to adjacent arterials or public facilities, such as schools and parks, shall be provided at the dead-end of the street to shorten walking distances. This requires right-of-way dedication and/or easements. Adopted December 2009 Chapter 7—Street Elements 7-10 CITY OF SPOKANE VALLEY STREET STANDARDS 7.5.11.1 Temporary Turnarounds Temporary turnarounds shall be approved by the City and are allowed only when there is the possibility for extending the street to connect adjacent parcels or other streets. Standard Plans R-131 and R-132 provide acceptable temporary turnarounds for public streets. For public streets, the turnaround shall be placed within an easement. Curb, gutter, and sidewalk shall be provided to the locations specified in standard plans. The plan shall include language indicating that the easement is to be vacated when the street is extended across the adjacent parcel. For private streets, the turnaround shall be part of the access easement and not part of the driveway approach. It is the responsibility of the Applicant to verify that setback requirements are satisfied for the lots with the turnaround. A sign shall be posted at the back of the temporary turnaround stating that the street is planned to be extended in the future (Standard Plan R- 142). 7.5.11.2 Permanent Turnarounds Permanent cul-de-sacs shall be provided for approved dead-end public streets (see Standard Plan R-130). For private streets and driveways, cul-de-sacs are the preferred turnaround; hammerheads or other turnaround types (Standard Plan R-133) are only allowed for private streets when approved by the City and the Fire Department. A permanent dead-end street is only allowed when connection to adjacent properties and/or other streets is not needed or possible. Permanent cul-de-sacs shall be constructed with curb, gutter, sidewalk and swales. The grade of the cul-de-sac bulb shall be a minimum 1 percent at all places along the gutter lines. As topography permits, drainage shall be directed away from the bulb. 7.5.12 BIKEWAYS The minimum design standards for bikeways shall be per AAHSTO Guide for the Development of Bicycle Facilities, latest edition. Typically, bikeways are shared with other transportation modes, although they may be provided exclusively for bicycle use. Types of bicycle facilities and planned bicycle facilities within the City can be found in Chapter 3 of the City of Spokane Valley Comprehensive Plan. 7.5.13 INTERSECTIONS 7.5.13.1 General Design Street intersections shall be laid out so the streets intersect as nearly as possible at right angles. If a right angle is not possible, the skew shall Adopted December 2009 Chapter 7—Street Elements 7-11 CITY OF SPOKANE VALLEY STREET STANDARDS not vary more than 15 degrees from a right angle. Opposite street legs shall lie on a straight line, whenever possible. For safe design, the following shall be avoided: a. Intersections with more than four intersecting streets; b. "Y"type intersections where streets meet at acute angles; and, c. Intersections adjacent to bridges, horizontal curves, and vertical curves and other sight obstructions. When a private street intersects a public street, the private street is required to be stop-controlled. A private street is not allowed as the fourth leg of the intersection at existing tee intersections. The minimum return radii shall be per Tables 7.2 and 7.3. 7.5.13.2 Approach Length The street approach area is where vehicles store while waiting to enter an intersection, and shall be designed with a nearly flat grade. For public or private streets, the street approach area at an intersection shall have a downgrade approaching the intersection of no greater than 2 percent. An upgrade approaching the intersection shall be no steeper than 4 percent. The minimum length of the street approach area, measured from the intersected street's edge of curb face, or traveled way where curbs are not present, is to be in accordance with Table 7.4.

Minimum intersection spacing is measured from centerline to centerline. 7.5.14 STREET LAYOUT The internal local residential street network for a subdivision should be designed to discourage regional through traffic. Subdivisions shall be planned in a manner that minimizes the number of local street accesses to arterials and collectors. Street configuration shall conform to the following: a. Blocks lengths shall not exceed 600 feet except as provided in the zoning regulations for estate lots, unless unique characteristics associated with the land such as creeks, woods, or parks justify a longer length; b. Public streets, private streets, and driveways shall not be located closer than 2 feet from any point from an interior property line. The only exceptions to this rule are for public streets which shall extend to the plat boundaries to allow for future connection and for half-streets; c. Horizontal alignment within intersection area. The horizontal approach to an intersection shall be tangent for a minimum length as specified in Tables 7.1 and 7.3. Longer tangents are highly desirable. The tangent distance is measured from the curb line of one street to the first point of curvature on the intersecting street; d. Residential developments with greater than 30 single family dwelling units shall have a minimum of 2 street accesses that Adopted December 2009 Chapter 7—Street Elements 7-13 CITY OF SPOKANE VALLEY STREET STANDARDS meet the Fire Department separation requirement to ensure adequate emergency access; and, e. Multi-family developments with greater than 100 dwelling units shall have a minimum of two street accesses. 7.5.15 SURVEY MONUMENTS 7.5.15.1 General Requirements Surveys shall conform to all applicable state and local regulations (SVMC Title 20). Prior to any construction or maintenance activities within City right- of-way, a professional land surveyor licensed in the State of Washington (Surveyor) shall conduct a thorough search for all survey monuments. Any found monuments shall be referenced in accordance with current applicable state and local regulations. A copy of the references shall be filed in the office of the County Engineer. The Surveyor shall comply with WAC chapter 332-120. If monuments are found to be at risk by construction or maintenance activities, an approved copy of the Application Permit filed with the Washington State Department of Natural Resources (DNR) shall be provided to the City. 7.5.15.2 Monumentation a. The responsible Surveyor shall set permanent monuments as shown per Standard Plan R-145 with his/her registration number as follows: i. For placing new or replacement of section corners, quarter corners, closing corners, witness corners, and meander corners that have been disturbed or destroyed, the minimum acceptable monument is a 3/4-inch inside diameter iron pipe or a #5 (5/8-inch) steel reinforcing rod, 24 inches in length. The monument and cap shall be marked in conformance with state laws and regulations. Any of these corners in paved roads shall be covered by a cast iron monument case and lid per Standard Plan R-145. ii. For placing new or replacement of disturbed road intersection points on arterials, the minimum acceptable monument is a 1/2-inch inside diameter iron pipe or a #5 (5/8 inch) steel reinforcing rod, 24 inches in length. These monuments shall be covered by a standard cast iron monument case and lid per Standard Plan R-145. iii.

Monuments set in the residential street shall be as shown on Standard Plan R-145. iv. For placing new or replacement of all permanent monuments not covered above, the minimum acceptable monument is a 1/2-inch inside diameter iron pipe or a#4 (1/2- inch) steel reinforcing rod, 18 inches in length. v. If it is impossible to set the above monuments, the City may approve an alternative monumentation method. b. For each monument being set or established, the responsible Surveyor shall: i. Identify at least three reference points. The reference points may consist of, in order of preference, cross on curbs, bearing trees or accessories, nearby property corners or an alternate as approved by the City. A completed DNR permit shall be filed with the DNR with a copy supplied to the City. ii. Show on a Record of Survey, Subdivision, Short subdivision or Binding Site Plan sufficient information to comply with RCW 58.09.120. A filed copy of said Record of Survey, Subdivision, Short Subdivision or Binding Site Plan shall be supplied to the City as needed. 7.5.15.3 H or i zonta I Control N etwor k A horizontal control network previously established by the Spokane County Engineer shall be the mapping base for all surveys performed under these Street Standards. Intersections shall also be located and referenced to the current control network as established by the Spokane County GPS control project and that coordinate system. Refer to the SVMC Title 20.40 for additional information. All survey work done within the City boundaries shall conform to the degree of accuracy required under applicable state laws. Adequate supplemental information may be required by the City to ensure accuracy. 7.5.15.4 Temporary Bench Mark The Surveyor shall provide a temporary bench mark along the roadway every 1,000 feet. These temporary bench marks shall be based on the datum plane approved by the City. Refer to the SVMC Title 20.20 for additional information. If requested by the City, the Surveyor shall submit field notes or a sealed statement, insuring work according to third order accuracy. Refer to Washington State Department of Transportation Standards (Highway Surveying Manual M22-97) for additional information. Adopted December 2009 Chapter 7—Street Elements 7-15 CITY OF SPOKANE VALLEY STREET STANDARDS 7.5.16 TRAFFIC CONTROL DEVICES The City uses the Washington State MUTCD as a guideline for traffic control devices including pavement marking and signing. The Applicant is responsible for providing and installing all required traffic control devices, including but not limited to street name signs, regulatory signs (including stop and no parking), warning signs, barricades, crosswalk markings, and bicycle/pedestrian signs. "No Parking" signs shall be posted on both sides of the street for curb to curb widths up to 26 feet and on one side of the street for curb to curb widths greater than 26 feet and up to 32 feet. If the street has no curb, the pavement width shall be used to determine if "No Parking" signs are required. For private streets and private driveways, a minimum of one "No Parking — Fire Lane" sign shall be installed every 100 feet of frontage or as required by the Fire Department. "No Parking" signs on public streets shall be installed when required by these Street Standards at a separation as required by the City and the Fire Department. 7.6 ROADSIDE ELEMENTS 7.6.1 SIDEWALKS Sidewalk is required on public streets along both sides for all street classifications. When approved by the City, the sidewalk may be eliminated on one side of the street if topography or safety prohibits construction. The Applicant shall demonstrate that pedestrian needs are still satisfied. Additionally, sidewalk may not be required on a local access street fronting the project if all of the following are true: a. The project is in a low-pedestrian zone (zones R-1, R-2, R-3, I-2); b. There are no other sidewalks within its block; and, c. Any part of the project is more than one mile radially away from an activity center (which includes but is not limited to parks, schools, large employment centers, religious institutions). The width of sidewalks shall be as required in Tables 7.2 and 7.3. Wider sidewalk may be required to provide corridor continuity. At no location shall a sidewalk provide an unobstructed path of less than the required width. Wider sidewalk may be required at bus stops to allow bus riders a place to stand without hindering pedestrian movements or handicap access. When the existing sidewalk is not continuous along the street frontage, the Applicant shall construct sidewalk along the frontage of the project to provide continuity. The thickness of the sidewalk shall be per Standard Plan R-103. Adopted December 2009 Chapter 7—Street Elements 7-16 CITY OF SPOKANE VALLEY STREET STANDARDS Meandering sidewalks may be approved by the City. The design of meandering sidewalks shall address obstructions, including mailbox mountings, street trees, fire hydrants, power poles, driveways, swales and street signs, without deviation from the required design width. Additional right-of-way (or easement) may be required to accommodate the obstructions or the meander of the sidewalk. 7.6.2 PEDESTRIAN RAMPS Pedestrian ramps shall be provided at all pedestrian crossings having vertical curb sections and shall be per Standard Plans R-105 and R-106. Every pedestrian ramp shall have at least one receiving ramp. This may require construction of"island" landing ramps. In special conditions, pedestrian ramps shall also be provided to enable passage across curbed radius return access points. Pedestrian ramps shall have detectable warning patterns formed with manufactured truncated domes in yellow. Pedestrian ramps are required to meet all ADA guidelines. 7.6.3 SIDE SLOPES Typical slopes for embankments should be 3:1 or flatter. The steepest slope for embankment or excavation shall be 2:1. Refer to Chapter 5 for additional requirements. On shouldered streets, a minimum space of 5 feet shall be provided between the catch point of the side slope and the right-of-way line for the installation of utility poles, fences, sloped rounding, etc. Depending on site conditions, this may require additional right-of-way, retaining walls, or other requirements. The maximum slope of this space shall be 3:1. Slope easements shall be granted to the City when required by terrain or design features. 7.6.4 CLEAR ZONE Clear zone is defined as a relatively flat area void of fixed objects or obstructions beyond the edge of the traveled way that allows drivers to stop safely or regain control of a vehicle that leaves the traveled way. This area may consist of a shoulder, a recoverable slope, a non-recoverable slope, and/or a clean run-out area. The desired minimum width is dependent upon traffic volumes, traffic speeds, side slopes, and the street geometry. A recoverable slope is a slope on which a motorist may retain or regain control of a vehicle by slowing or stopping. Slopes flatter than 4:1 are generally considered recoverable. A non-recoverable slope is considered to be traversable but on which an errant vehicle continues to bottom. Embankment slopes between 3:1 and 4:1 may be considered traversable but non-recoverable if they are smooth and free of fixed objects. A clear run-out area is the area at the top of a non-recoverable slope available for safe use by an errant vehicle. Slopes steeper than 3:1 are not considered traversable and are not considered part of the clear zone. Adopted December 2009 Chapter 7—Street Elements 7-17 CITY OF SPOKANE VALLEY STREET STANDARDS For streets with Type B or Type A curb, the following is required: a. Sidewalk adjacent to the curb - Rigid objects shall be placed 2 feet behind the sidewalk; b. Separated sidewalk - Rigid objects shall be no closer than 2 feet from the back of the curb; c. No sidewalk- Rigid objects shall be no closer than 2 feet from the back of the curb; d. Speed limit 40 mph or less - The clear zone distance is 2 feet behind the back of the curb. For all other pavement edges and design speeds, clear zone requirements per AASHTO's "A Policy on Geometric Design of Highways and Streets" shall be used. 7.6.5 SIGHT DISTANCE Sight distance is defined as the length of roadway that is entirely visible to the driver. All roads, intersections, and access points shall be designed to provide adequate sight distance for all normal driving situations and are required to conform to AASHTO's "A Policy on Geometric Design of Highways and Streets, " latest edition. Stopping sight distance shall be calculated for vehicle crest curves and horizontal curves. The stopping sight distance shall not be less than the distances specified in Table 7.6. These values should be adjusted for grades 3 percent or greater, more than 2 lanes, skewed intersections, intersections near vertical or horizontal curves, or for design vehicles other than passenger cars. Adopted December 2009 Chapter 7—Street Elements 7-18 CITY OF SPOKANE VALLEY STREET STANDARDS TABLE 7.6 MINIMUM STOPPING SIGHT DISTANCE Design Speed Stopping Sight (mph) Distance (feet) 20 115 25 155 30 200 35 250 40 305 50 425 55 495 Table 7.7 specifies the required sight distance for different types of intersections and approaches. These values shall be adjusted for grades with slopes of 3 percent or greater, number of lanes greater than two, for design vehicles other than passenger cars, using the procedures in the AASHTO design guidelines. For intersections or approaches located near horizontal or vertical curves, the City may require the 85th-percentile speed be used in the sight distance analysis. The 85th percentile speed is the speed at or below which 85 percent of the motorists drive on a given street unaffected by slower traffic or poor weather. This speed indicates the speed that most motorists on the street consider safe and reasonable under ideal conditions. Sight distance triangles shall be shown in the civil plans for all new intersections and all projects with new driveway approaches. Sight distance shall be continuous. Non-engineered driveways on local access streets are exempt from this requirement. Sight distance triangles shall be developed by an Engineer with traffic engineering experience developing intersection sight distance triangles. Fire hydrants shall be visible for 50 feet in either direction. A sight distance triangle shall be shown at the location of each fire hydrant in the civil plans and lot plans. The area within the sight distance triangle shall be free from any sight-obscuring objects in accordance with AASHTO design guidelines. Sight-obscuring objects include but are not limited to buildings, parked vehicles, signs, fences, and landscaping. For sight triangles in the right-of-way, only grass may be planted. The City may remove, at the expense of the property owner, any vegetation or objects which obstruct sight distance. Adopted December 2009 Chapter 7—Street Elements 7-19 CITY OF SPOKANE VALLEY STREET STANDARDS The sight distance triangle shall be located completely within an easement or right-of-way. The property owner is responsible for removing any objects that become a sight hazard. If an easement is not practical, the City may require additional right-of-way as a condition of development approval to ensure proper maintenance.

End anchors shall conform to WSDOT/APWA Plan C-6, Beam Guardrail Anchor Type 1. 7.7.4 BOLLARDS Points of access shall be closed by a line of bollards when necessary to deny vehicle access to an easement, tract, or trail (except for maintenance or emergency vehicles). Bollards shall be wrapped with reflective tape. Closure shall include one or more fixed bollards on each side of the traveled way and removable, locking bollards across the traveled way. Spacing shall provide one bollard on centerline of the trail and other bollards at a maximum spacing of 3 feet to preclude vehicular access. Fire access roads shall not be blocked in this manner without the approval of the Fire Department. Reflective tape and safety striping shall be placed on bollards. Bollards shall be placed 10 feet from the paved edge of roadway. Adopted December 2009 Chapter 7—Street Elements 7-22 CITY OF SPOKANE VALLEY STREET STANDARDS 7.7.5 ROADWAY BARRICADES Temporary and permanent barricades shall conform to the Manual on Uniform Traffic Control Devices (MUTCD). Type III barricades (see Standard Plan R- 142) shall be used at the end of a local access street terminating abruptly without cul-de-sac bulb or on temporarily stubbed off streets. Each such barricade shall be used together with an end-of-road marker and signed future street extension. 7.7.6 ENTRANCE GATES Entrance gates are not allowed on public streets. Use of entrance gates on private streets shall be approved by the City and the Fire Department. Minimum gate opening width is 20 feet. Proposed gates shall be clearly shown on the street plans. If a center island is used as part of an entrance gate feature, a minimum 14-foot wide lane between face of curb and center island shall be provided. The center island shall not extend past the end of the gate when it is fully opened. Gated streets require a queuing area to allow vehicles to exit the connecting street prior to the gate. The queuing length shall be a minimum of 35 feet plus the gate width. Parking is not allowed within the queuing area, on either side of the street, for a distance equal to the queuing length. Signage for the "No Parking Zone" shall be placed on both sides of the gate. Gates shall be required to have a Fire Department emergency access device installed and maintained: a. A Knox key switch shall be installed on gates that provide access to 20 lots or less; or, b. An Opticom gate activation device shall be provided for subdivisions with more than 20 lots. 7.8 APPROACH DESIGN CRITERIA The following section contains design criteria for intersections and driveway approaches. These are minimum requirements and may be modified if traffic volumes (existing and/or projected), topography, design speed, design vehicle requirements, drainage, and other conditions, both existing and projected indicate a more stringent criterion is necessary. The City may require additional provisions to ensure public safety. All access points to and from City streets, including intersections and driveways shall be approved by the City prior to construction and require an approach permit. 7.8.1 APPLICABILITY These requirements apply to all new or altered intersection and driveway approaches to City streets. Adopted December 2009 Chapter 7—Street Elements 7-23 CITY OF SPOKANE VALLEY STREET STANDARDS 7.8.2 ACCESS LIMITATIONS a. While no property is denied access to City streets, direct street access is not guaranteed. When direct access is denied, properties may be required to: i. Access the street via an alley; ii. Share a single driveway approach with two or more contiguous properties; or, iii. Restrict access with a right-in/right-out approach for properties located on arterials and with no available alternate access. Additionally, these properties may be required to construct street improvements to preclude left turning traffic. b. Properties are restricted to one access point on arterials and two access points on local access streets. The Development Services Senior Engineer after consultation with the Senior Traffic Engineer may grant one additional arterial access point provided that: i. Minimum spacing requirements between access points are met with any driveway approaches; ii. The applicant demonstrates that additional access points will result in an improvement to safety or traffic flow both on-site and off-site; and, iii. One of the following situations exists: 1. The PM peak hour volume exceeds 100 PM peak hour vehicles on both directions; or, 2. Traffic volumes using one driveway would exceed the capacity of a stop sign controlled intersection during the PM peak hour; or, 3. The ADT using one driveway would exceed 1,000 vehicles both directions. c. When a property has frontage on two or more streets, and spacing requirements on the major street cannot be met, the driveway approach shall be located on the street with the lowest classification unless safety considerations dictate otherwise. d. For a development that combines more than one underlying lot, these requirements, including the number and spacing of access points, shall apply to the development as a whole, not to each underlying lot. e. For all Binding Site Plans, excluding industrial zones, shared access is required between the lots. The shared access shall include parking lot travel lane connections or shared driveway approach. If the Applicant adequately demonstrates a site design or building use limitation for installation of the travel lanes or shared approach on the existing property, exceptions to this requirement may be administratively granted. Exceptions may be approved if: Adopted December 2009 Chapter 7—Street Elements 7-24 CITY OF SPOKANE VALLEY STREET STANDARDS i. The City finds that the lack of shared access does not negatively impact the present or future function and safety of the parking lot circulation, ingress/egress, or roadway network; and, ii. The City finds that the lots required to share access have allowable incompatible uses; and, iii. The property does not have a feasible alternative site design solution. f. Driveways will not be allowed where horizontal or vertical curves prevent the roadway from having continuous stopping sight distance or adequate intersection sight distance to safely accommodate the movements in and out of the driveway. 7.8.3 GENERAL DESIGN Approaches shall be constructed to avoid interference with existing drainage inlets, culverts, lighting, utility poles, traffic regulating devices, fire hydrants, or other facilities. The Applicant shall be responsible for the cost of relocating any of the above. The agency holding authority for the particular structure shall decide how the facility will be relocated. If at the time of construction the fronting street does not have full width pavement or curb and gutter, a rural driveway approach may be used with the approach starting at the edge of the existing pavement(see Standard Plan R-114). Approaches shall not restrict or impound drainage flow in the street. For shouldered streets with ditches, stormwater shall be conveyed under the driveway with a culvert. The minimum culvert size shall be 12 inches. For curbed roads, stormwater shall be conveyed using a culvert and Standard Plan R-110 or an inverted approach per Standard Plan R-111. If an existing approach is to be altered or abandoned the unused portion of the original approach is to be removed and replaced with curb, gutter and sidewalk matching that which is adjacent. Redevelopment projects shall be required to modify or eliminate any existing driveway approach that does not conform to these standards. 7.8.4 DRIVEWAY APPROACH HORIZONTAL AND VERTICAL GRADE Approaches shall align perpendicular to the street. The angle of intersection to the street shall not be less than 75 degrees. The angle may be reduced to 45 degrees for right-in/right-out driveways where the entering and exiting lanes are separated by a raised"pork chop" island(see Standard Plan R-115). The vertical grade of approaches shall not exceed 8 percent within the right-of- way and shall be designed to preclude vehicles dragging when entering or exiting the site. Vertical grades shall not exceed 10 percent within ten feet of the right- of-way. Adopted December 2009 Chapter 7—Street Elements 7-25 CITY OF SPOKANE VALLEY STREET STANDARDS 7.8.5 APPROACH WIDTHS The total approach width shall not be greater than 50 percent of total lot frontage width. When approaches are constructed different than that shown on the construction plans, the design engineer shall verify that any affected street and stormwater facilities will still meet the design goals. If the facilities are inadequate, measures shall be taken to bring the facilities into compliance prior to their acceptance. 7.8.5.1 Single Family Residential Single family driveway approach shall be per Standard Plans R-110 through R-112. 7.8.5.2 Residential Private Streets Approach for private streets shall match the required pavement width and shall be per Standard Plans R-110 and R-112. 7.8.5.3 Commercial/Industrial Commercial/industrial driveway approaches shall be per Standard Plans R-110 through R-112. High volume driveway approaches (Standard Plan R-113)may be required or permitted when all of the following conditions are present: a. The access is located along an arterial; b. Access volumes indicate a need for a radii curb return where the ADT exceeds 500 or where speed change lanes would be required; c. The access is designed to restrict turning movements, requiring the installation of an access island or center median; d. The roadway has no curb and gutter; e. The access serves an industrial property, or provides for commercial deliveries, where large truck movements are required; and, f. A traffic engineering analysis submitted by the applicant determines that a radii access is necessary to ensure adequate traffic safety and operation. 7.8.6 DRIVEWAY APPROACH ON-SITE LAYOUT Approaches shall provide access to an off-street parking area located on private property. The driveway shall be of sufficient length so a vehicle in the driveway does not project into the right-of-way, sidewalk, or pathway. Approaches and on- site parking shall be designed such that vehicle-backing maneuvers will not occur into the street/public right-of-way, impede pedestrian access to sidewalk or vehicles in the public street. Driveway approaches shall be designed to allow the largest typical vehicle using the approach (i.e. tractor trailers at large warehouses, Adopted December 2009 Chapter 7—Street Elements 7-26 CITY OF SPOKANE VALLEY STREET STANDARDS delivery trucks at mini marts, etc.) to enter and exit the site without encroaching into opposing traffic. Whenever possible, the site should be designed for counterclockwise circulation of large trucks as left turns and left-hand backing maneuvers are easier and safer since the driver's position is on the left hand of the vehicle. All parking, loading and maneuvering of trucks shall be conducted on private property. 7.8.6.1 Driveway Stacking Length for Multi-use Properties Driveway stacking length for multi-use properties is the distance between the right-of-way and the near side of the first intersecting interior aisle or parking space. The driveway stacking length for multi-use properties shall be as follows: a. 20 feet for parking lots with less than 50 spaces; b. 50 feet for parking lots with up to 200 spaces; and, c. 80 feet for parking lots with over 200 spaces. 7.8.6.2 Driveway Stacking Length for Single-use Properties Driveway stacking length for single-use properties is the distance between the right-of-way and the proposed uses. The minimum length for driveway stacking for drive-thru windows shall be as follows: a. 150 feet for drive-in banks and drive-thru restaurants; b. 50 feet for automated tellers (ATM) and drive-in cleaners and repair services; c. 75 feet for automated car wash and espresso stands; and, d. 100 feet for controlled access parking. The City may require a traffic study to determine the stacking and queuing requirements for such uses that include, but are not limited to, service stations, drive-thru restaurants, drive-in banking, etc. The City may require sites with internal traffic congestion to design approaches with long throat lengths to provide extra storage to avoid impacting City streets. 7.8.7 CORNER CLEARANCE FROM INTERSECTIONS The following sections provide minimum corner clearances. Greater corner clearances may be required at the discretion of the City based on existing or proposed conditions at the intersection. In general, full access driveways are not allowed within the functional intersection boundary, which can be minimally defined by the length of the turn pockets, but may extend further from the intersection. Where the driveway location does not meet minimum City criteria, or where a safe driveway location cannot be found, the City requires appropriate mitigation measures to provide for as safe a driveway as feasible. Adopted December 2009 Chapter 7—Street Elements 7-27 CITY OF SPOKANE VALLEY STREET STANDARDS 7.8.7.1 Single Family Residential Residential driveway approaches may not be located closer than 15 feet from the point of curvature of a curb return. 7.8.7.2 Commercial/Industrial Commercial driveway approaches may not be located closer than 75 feet from the point of curvature of a curb return. 7.8.8 DRIVEWAY APPROACH SPACING - SAME SIDE OF STREET Table 7.8 provides the minimum distance allowed between the centerlines of adjacent driveway approaches. The distance is measured from centerline to centerline of each approach. TABLE 7.8 -DRIVEWAY APPROACH SPACING STREET DESIRABLE LIMITING CLASSIFICATION CONDITIONS CONDITIONS SEPARATION (FT) SEPARATION (FT) Collector 70 50 Minor Arterial 90 60 Principal Arterial 120 80 Desirable conditions shall be applied when sufficient space or street frontage is available. If sufficient space or street frontage for desirable conditions is not available, then lesser distances, down to, but not less than the requirement for limiting conditions,may be applied. 7.8.9 DRIVEWAY APPROACH METHODS OF MEASUREMENTS Driveway throat width is measured perpendicular to the centerline of the driveway between lines defined by the radii, whether or not that occurs inside the property lines and is physically marked with curbing. Driveway throat length is measured along the centerline of the driveway from the back edge of the driveway apron and the nearest vehicle aisle or circulation road. Dimensions in this section refer to distances from (or along) face of curb. In the absence of a curb, the measurement is considered to be from (or along) the edge of pavement. Driveway angles are measured between the driveway centerline and centerline of the roadway. 7.8.10 RESTRICTED ACCESS DRIVEWAYS Restricted access approaches do not allow left-hand turns out of or into the driveway approach. Development or redevelopment of properties, where the Adopted December 2009 Chapter 7—Street Elements 7-28 CITY OF SPOKANE VALLEY STREET STANDARDS required setback from an intersection cannot be achieved in any direction and without other ways to access the site, may be required to use a restricted access driveway. In some cases a raised median may be required down the street centerline. Restricted access approaches shall only be allowed when approved by the City. The existence of other approaches in the vicinity that do not meet standards is not grounds for allowing further substandard approaches. 7.8.11 ALIGNMENT OF CROSS-STREET DRIVEWAY APPROACHES Driveways should be placed directly opposite from each other whenever possible. If this is not possible and adequate left-turn storage capacity is not available in advance of each driveway, combining of driveways on the same side of the street may be required. The requirement above shall not apply if the street to be accessed has a permanent median and/or traffic control device that prevents any cross-street movement of traffic or if the City determines that adhering to said requirement would be unsafe. 7.8.12 SIGNALIZED DRIVEWAY APPROACHES If the Traffic Impact Analysis determines that there is or will be a need to signalize proposed access points, then proposed access points shall be aligned directly opposite any existing or proposed access points or T-intersection across the street. Where driveways are to be signalized, a minimum spacing of 1,320 feet to any other signalized intersection should be maintained or shall be spaced as approved by the City. Roundabouts may be considered as an alternative option by the City. 7.8.13 APPROACHES ON STATE HIGHWAYS This section contains specific access standards for state highways within the City limits,which are classified as managed access facilities. Managed access is based on the premise that access rights of a property owner are subordinate to the public's right and interest in a safe and efficient highway system. In accordance with RCW Chapter 47.50, the City adopts by reference, the provisions of WAC Chapter 468-52, together with all future amendments, in order to regulate and control vehicular access and connection points of ingress to and egress from, the State Highway System within the incorporated areas of the City of Spokane Valley. State Routes (SR) within the City include SR-27 (Pines Road) and SR-290 (Trent Avenue). The current access classifications for SR-27 and SR-290 are shown in Table 7.9.

The Applicant may utilize one or more of the traffic calming devices. Proposed devices shall be reviewed and approved by the City at the time of preliminary design review. Traffic calming devices shall be installed at the expense of the Applicant. 7.9.2 EXISTING DEVELOPMENT Traffic calming devices are not allowed on arterials. On collectors and local access streets, traffic calming devices are only allowed when warranted by an engineering study and approved by the City. The installation of devices shall be neighborhood funded. 7.9.3 TRAFFIC CALMING DEVICES Currently, the only traffic calming device allowed by the City is the Traffic Circle (see Standard Plan T-101). Alternative devices recommended by the Applicant's Engineer may be permitted with City approval.

The use of these design criteria will ensure that paved transportation corridors are improved in a uniform and consistent manner. The requirements presented in this chapter have been established to minimize structural failures in streets, due to traffic loadings and/or existing soils conditions. 8.2 STREET CLASSIFICATION All public streets in the City have been classified using the Federal Functional Classification system, which provides a hierarchy from principal arterials to local access streets, to accommodate existing and anticipated traffic. Street classifications can be found in the City of Spokane Valley's Comprehensive Plan. A street's classification is used to determine the volume and mix of vehicles for which it is designed. In cases where a street has yet to be designated a specific classification, the anticipated traffic volume should be used. If available, the City may provide the anticipated daily traffic for a street. However, the Applicant may be required to obtain additional traffic information. 8.3 STREET PAVEMENT AND SUBGRADE 8.3.1 TRAVELWAYS IN RESIDENTIAL ZONES The requirements of this section apply to local access streets, private streets, alleys, and private driveways located in residential zones. For the purpose of pavement design, the engineering characteristics of the subgrade soil shall be determined through laboratory testing. Laboratory testing consisting of California Bearing Ratio (CBR) testing, Resilient Modulus (Mr) testing or Resistance Value (R-value) testing may be used to characterize the subgrade soil supporting capability. A minimum street section of 3 inches of hot mix asphalt (HMA) over 6 inches of properly placed and compacted crushed rock is required for local access streets, private streets, and alleys regardless of native soils. A minimum pavement section of 2 inches of HMA over 6 inches of crushed rock is required for private driveways. A soils investigation is required for all projects. The minimum pavement section cannot be used for sites with poor subgrade soils, which are soils that meet any of the criteria below: a. Have CBR less than 3; b. Have R-values less than 20; c. Have Mr values less than 3,000 psi; or, Adopted December 2009 Chapter 8 Pavement Design 8-1 CITY OF SPOKANE VALLEY STREET STANDARDS d. Are classified as MH, CL, CH, OL or peat in accordance with the Unified Soil Classification System. When results of laboratory testing indicate that poor subgrade soils are present, an engineered pavement design is required. Subsurface explorations (borings/test pits) are required for each travelway to demonstrate the subgrade soils meet the criteria above. Exploration should extend to a depth of at least 5 feet below proposed pavement subgrade. 8.3.2 TRAVELWAYS IN NON-RESIDENTIAL ZONES Engineered pavement design is required for commercial local access streets, commercial alleys, collector arterials, and arterials. The resilient modulus value can be acquired using the following methods: a. Mr testing: Soil samples shall be obtained and sent to a private lab for testing. The proposed street shall have a minimum of one laboratory test for every 1,000 feet of street and/or for every obvious change in subgrade material (minimum of 3 tests per street). b. CBR testing or R-value testing: Soil samples shall be obtained and sent to a private lab for testing. The proposed street shall have a minimum of 1 laboratory test for every 1,000 feet of street and/or for every obvious change in subgrade material (minimum of 3 tests per street). A geotechnical engineer shall be retained to provide recommendations for correlations between CBR or R-value results and Mr values. c. In-situ testing using a non-destructive deflection test method: The Applicant shall obtain approval from the City for the type of non- destructive deflection test method proposed, before conducting the testing. For non-destructive deflection testing, a statistical analysis is needed. The results shall be reported by street stationing. Test results shall include a graph of the resilient modulus values vs. street stationing. The graph shall be included in the pavement design report. A minimum street section of 4 inches of HMA over 6 inches of properly placed and compacted crushed rock is required regardless of the pavement design results in accordance with Section 8.4. 8.3.3 SUBGRADE PREPARATION Prior to placing any street base material, the subgrade shall be rolled and compacted to a minimum of 95 percent of the maximum dry density as determined by ASTM D-1557 (Modified Proctor). This degree of compaction shall extend to a depth of at least 1 foot below pavement subgrade elevation in cut areas. The fill areas shall be compacted to at least 95 percent of the maximum dry density based on ASTM D1557 and WSDOT Standard Specification 2-03.3(14)C Compacting Earth Embankments, Method C. Fill placed more than 2 feet below pavement subgrade elevation shall be compacted to at least 95 percent of the maximum dry density based on ASTM D1557. Adopted December 2009 Chapter 8 Pavement Design 8-2 CITY OF SPOKANE VALLEY STREET STANDARDS Any street section which cannot be compacted to the degree specified above shall be removed to a depth of 2 feet or to a depth where the pumping ceases, or as directed by the Onsite Inspector, and replaced with granular imported material that can be compacted to at least 95 percent of the maximum density as determined by ASTM D-1557, or as directed by the Onsite Inspector. Prior to placing any sub-base or base materials, geo-textile fabric on the subgrade may be required if the existing subgrade is a fine-grained soil (ML, CL, MH, or CH). The geotextile fabric shall meet the criteria in Section 9.33 for"Separation" of the most current version of the WSDOT Standard Specifications. If the material is unsuitable, the soil shall be excavated below grade and compacted per WSDOT Standard Specification 2-03.3(3) and 2-03.3(14)Method C. 8.4 ENGINEERED PAVEMENT PARAMETERS Engineered pavement designs shall be in accordance with the 1993 AASHTO Guide for Design of Pavement Structures for flexible pavements and the following criteria: 8.4.1 TRAFFIC PARAMETERS The existing traffic levels shall be increased to match the projected traffic at the end of the street design life. The minimum design life shall be 20-years. The growth rate is 1.5 percent for residential streets and 3.5 percent for commercial/industrial streets and arterial streets. The 1.5 percent growth rate may be waived in closed subdivisions with City approval. This growth rate shall only be used for pavement design purposes and shall not be used for traffic analyses. The engineer shall submit Equivalent Single-Axle Loads (ESALs) calculations. The truck factors found in Table 8.1 may be used in the absence of other information. TABLE 8.1 —EQUIVALENT SINGLE AXLE LOADS VEHICLE TYPE TRUCK FACTOR (ESALs/VEHICLE) School Bus 2.87 STA Bus 2.57 Refuse Truck 1.03 All other trucks (averaged) 0.42 8.4.2 RELIABILITY LEVEL The reliability level (R) for residential streets and local non-residential streets is 75 percent. For all other street classifications, the reliability level is 90 percent. Adopted December 2009 Chapter 8 Pavement Design 8-3 CITY OF SPOKANE VALLEY STREET STANDARDS 8.4.3 OVERALL STANDARD DEVIATION The overall standard deviation (S) is 0.45 for new construction and 0.49 for overlay projects. 8.4.4 INITIAL ANDTERMINAL SERVICEABILITY INDEXES The initial and terminal serviceability indexes shall be per Table 8.2.

The crushed aggregate shall have at least 90 percent by weight of particles with at least one fractured face. The area of each face shall be equal to at least 75 percent of the smallest mid-section area of the piece. 8.6.3 ASPHALT OR CONCRETE TREATED BASE When compaction soils type or moisture content precludes proper compaction, asphalt treated base (ATB) or concrete treated base (CTB) should be utilized. 8.6.4 HOT MIX ASPHALT Hot mix asphalt shall be in accordance with the current edition of the WSDOT Standard Specifications. Pavement design calculations shall be performed by an Engineer experienced with performance grade oils and pavement design calculations. Asphalt used in City street construction shall use performance grade asphalt binders, in accordance with AASHTO Designation MP-1. The minimum base binder used shall be PG-64-28. Required base binders based on street type and condition are provided in Table 8.6. TABLE 8.6—PERFORMANCE GRADE STREET CLASSIFICATION PERFORMANCE GRADE Local access,private streets, and alleys 64-28 Collectors and arterials 70-28 Aggregate for use in hot mix asphalt shall be Class 1/2—inch in accordance with Section 9-03.8(1) of the WSDOT Standard Specifications. 8.6.5 IN-PLACE MAINLINE ASPHALT COMPACTION TEST REQUIREMENTS A lot consists of 5 random individual tests. Minimum density testing requirements are 1 lot per 400 tons of HMA or 1 lot per day, whichever results in the greater number of lots. A lot shall be rejected if any of the following occurs: a. The average compaction of the lot is less than 92 percent of maximum density, as determined by WSDOT FOP for AASHTO T166 and T209; or; b. Any individual compaction test in the lot is less than 91 percent or higher than 96 percent of the maximum density, as determined by WSDOT FOP for AASHTO T166 and T209.

Adopted December 2009 Chapter 8 Pavement Design 8-6 CITY OF SPOKANE VALLEY STREET STANDARDS 8.6.6 COLD JOINT REQUIREMENTS Section 5-04.3(10)B of the WSDOT Standard Specifications for Road, Bridge, and Municipal Construction, 2008 edition is supplemented with the following: a. Extreme care shall be exercised in the construction of cold joints to insure that the joint is properly tacked with a uniform and heavy coating of an approved tacking agent, that the placement of HMA adjacent to the cold joint is properly raked and that the adjacent hot mix is rolled and compacted in such a manner so as to completely seal the joint. The formation of all joints shall be made in such a manner as to ensure a continuous bond between the courses and obtain the required density. All joints shall be the same texture as other sections of the course and meet the requirements for smoothness and grade. b. If in the opinion of the City, the cold joint has not been properly constructed the joint shall be sealed with a joint compound sealant as per AASHTO M 324, at the Contractor's own expense. 8.6.7 LONGITUDINAL AND TRANSVERSE JOINT REQUIREMENTS Section 5-04.3(12) Joints of the WSDOT Standard Specifications for Road, Bridge, and Municipal Construction, 2008 edition is supplemented with the following: a. The formation of all joints shall be made in such a manner as to ensure a continuous bond between the courses and obtain the required density. All joints shall be the same texture as other sections of the course and meet the requirements for smoothness and grade. b. When paving occurs on an arterial street within the City of Spokane Valley, cold joints will be limited to the centerline of the roadway and shall be constructed per Standard Plan R-127-Step Wedge Longitudinal Cold Joint. A paving plan shall be submitted, to Public Works, detailing how the work is to be accomplished. Where possible the Contractor is required to use multiple pavers in order to reduce or eliminate longitudinal joints. 8.6.8 TACK COATS — PREPARATION OF EXISTING SURFACES Section 5-04.3(5)A, paragraph 2 of the WSDOT Standard Specifications for Road, Bridge, and Municipal Construction is hereby amended as follows: a. A tack coat of asphalt shall be applied to all paved surfaces on which any course of HMA is to be placed or abutted. Tack coat shall be uniformly applied to cover the existing pavement with a thin film of residual asphalt, free of streaks and bare spots. The application rate shall be 0.02 to 0.08 gallons of retained asphalt per square yard. If the tack coat has been diluted with water, as allowed in this section, then the application rate must be adjusted in order to achieve the retained amount of asphalt required. A heavy application of tack coat will be applied to all joints. Thin lifts of pavement require heavier applications of tack coat to prevent Adopted December 2009 Chapter 8 Pavement Design 8-7 CITY OF SPOKANE VALLEY STREET STANDARDS raveling, spalling and delamination. As a guide, existing surfaces that are coarse, dry or milled require a higher application rate of tack coat than surfaces that appear rich or bleeding. For streets open to traffic, the application of tack coat shall be limited to surfaces that will be paved during the same working shift. The spreading equipment shall be equipped with a thermometer to indicate the temperature of the tack coat material. 8.6.9 COVER ASPHALT LOADS DURING TRANSPORT Tarpaulin material shall be used to cover asphalt loads during transport from plant to project for all projects when the ambient air temperature is 50 degrees Fahrenheit or less. 8.6.10 BREAKDOWN ROLLING MAXIMUM TEMPERATURE LOSS Breakdown rolling shall occur before 20° F or greater temperature loss of the mix from the point of laydown. Temperature for basis shall be that observed and recorded in the transport vehicle at time of discharge to the paver. 8.6.11 ASPHALT TEMPERATURE PLACEMENT REQUIREMENTS Table 8.7 shows the minimum laydown temperatures and rolling times. Vibratory compaction shall not be used after the asphalt mat cools below 175°F. The rolling pattern shall be established in conjunction with asphalt density testing. TABLE 8.7 RECOMMENDED MINIMUM LAYDOWN TEMPERATURE MAT THICKNESS (INCHES) Base Temp, F 1/2 3A 1 1 1/2 2 >3 40-50 310 300 285 275 50-60 310 300 295 280 270 60-70 310 300 290 285 275 265 70-80 300 290 285 280 270 265 80-90 290 285 275 270 265 260 < 90 280 275 270 265 260 255 Rolling Time 4 6 8 12 15 15 (min) 1. Reference is Table 6-4 from the National Center for Asphalt Technologies, Hot Mix Asphalt, Mixture Design and Construction. 2. Time available between recommended laydown temperature and cessation temperature (175 °F) when attempts to compact the mat should cease. 3. These compaction temperatures are estimates and will vary with different asphalt cements and aggregates. For thin mats, the time available for rolling is short. For example, a 3/4-inch mat placed at the recommended minimum laydown temperature has only 6 minutes to be compacted to achieve the target density. The roller speeds cannot be increased significantly without adversely affecting density;hence,additional rollers may be required when paving at low temperatures. Adopted December 2009 Chapter 8 Pavement Design 8-8 CITY OF SPOKANE VALLEY STREET STANDARDS 8.6.12 PAVING DATES & WEATHER LIMITATIONS WSDOT Section 5-04.3(16)Weather Limitations is amended as follows: a.

If these items are deficient, the On-site Inspector shall notify the Contractor and/or Applicant's Engineer to determine a solution. Elevation Adopted December 2009 9-7 Chapter 9-Inspection&Certification CITY OF SPOKANE VALLEY STREET STANDARDS sensitive aspects of installed materials, such as drywell rims, etc., shall be verified as within normal industry tolerances (i.e., drywell rim elevations +/- 5/100'). At the discretion of the City, a test of the facility may be conducted to demonstrate adequate performance. The test shall be performed in the presence of the On-site Inspector and Development Inspector. All aspects of the drainage facility, including landscaping, irrigation, and establishment of specified vegetation, shall be completed in accordance with the accepted plans. An exception may be granted for single-family or two-family residential subdivisions where the completion of the swales is not practical until such time as the dwellings are constructed. In these cases, the Applicant shall rough-grade the swales to the required volume, install all drywells, inlets, and curb drops and other structures in accordance with the accepted plans. If the driveway approach width is greater than the width shown in the lot plans, engineering calculations shall be submitted that demonstrate that treatment and storage requirements are met. Erosion control measures shall be implemented to protect the installed drainage structures and to prevent erosion and/or failure of the swale side slopes. This includes, but is not limited to, lining the swale with geo-fabric that can be removed along with accumulated silt, until the swale is final-graded and vegetated. Completion of the landscaping, irrigation, and establishment of specified vegetation shall be required prior to issuance of the final Certificate of Occupancy or final inspection for any associated dwelling. For single and two-family dwellings, it shall be the responsibility of the Builder to satisfy these requirements. Acceptance of performance sureties, in lieu of establishing the vegetation, shall be permitted only when completion of improvements prior to final land action or permanent Certificate of Occupancy is impractical because of cold weather not suitable for the establishment of vegetation. 9.9.6 SWALE INSPECTION DURING WARRANTY PERIOD The Applicant's Engineer and the Development Inspector shall monitor performance of swales during the construction and warranty periods for proper percolation. Swales that do not percolate properly shall require corrective work or measures and are the financial responsibility of the Applicant. 9.10 MISCELLANEOUS 9.10.1 CHANGES DURING CONSTRUCTION Changes during construction that affect the scope of the project and/or the accepted individual lot plans shall be submitted for review by the City. The Development Inspector will determine if the change is significant. Minor changes Adopted December 2009 9-8 Chapter 9-Inspection&Certification CITY OF SPOKANE VALLEY STREET STANDARDS do not require City review, but shall be discussed with the Development Inspector and documented in the daily and weekly inspection reports. The Development Inspector shall review and approve any significant field changes to the design plans and permits that have prior approval. Review and acceptance of any changes to approved plans for utility, site improvements and street right-of-way work shall require the oversight of both the utility operator as well as the Development Inspector. 9.10.2 CONSTRUCTION COMPLAINTS Complaints from citizens regarding the project shall be documented and shared with the Development Inspector and resolved by the Applicant. On more significant or high profile projects, the City may assign a Public Information Officer to notify the public of the project schedule and provide weekly up-dates (See Section 9.6). 9.10.3 CONFLICT RESOLUTION During the construction process, occasional differences may arise between the Applicant's Engineer and/or Contractor and City staff regarding interpretation of policies, standards or guidance documents. When the Applicant's Engineer or Contractor does not agree with an interpretation made by City staff, the Applicant's Engineer may appeal to the Development Services Senior Engineer, as appropriate. The determination by the Development Services Senior Engineer is final. 9.11 FINAL W ALK -THROUGH When requested by the Applicant, the On-site Inspector and Contractor shall prepare a punch list. When the punch list items have been addressed, the Applicant shall schedule a final walk-through with the Development Inspector. If no deficiencies are found, the On-site Inspector shall then prepare a certification package in accordance with Section 9.13. If deficiencies are found, another final walk- through with the Development Inspector is required. The Applicant continues to be responsible for correction of all deficiencies until the City accepts the project unless as noted in Section 9.14. It is suggested that the Applicant consider taking verification photographs immediately following the final walk-through. Verification photographs can be helpful in resolving cases of damage by third parties (utility companies, builders, landscapers). 9.12 RECORD DRAWINGS All construction changes shall be recorded on a set of approved plans with the original approval stamp from the City. After the final walk-through, the Applicant's Engineer or On-site Inspector shall prepare record drawings for the project.
