This Functional Street Classification Plan designates streets as alley, local, hillside local, type I local, type II local, boulevard, lane, collector (major and minor), or arterial (major and minor). The following criteria apply to each classification. Standard roadway cross sections are presented in Appendix B, Details 1 to 11c. A. Planning Principles for Local Circulation Systems. The purpose of this section is to promote proper planning of traffic systems to help provide a safe and effective transportation network to meet existing and future demands within the Town. The goal of planning the transportation facilities is to create a network of roadways that connect, enhance circulation, and provide a balanced relationship between all roadways through coordination with developed land use plans (strategic and small area). Basic considerations in the design of local circulation systems must recognize the following factors: Safety - for both vehicular and pedestrian traffic Efficiency of Service - for all users Livability - especially as affected by traffic elements in the circulation system Economy - of both construction and use of land In addition, the Town encourages circulation systems that support and promote pedestrian and street life, and reserves the right to waive particular criteria if it serves to enhance downtown and pedestrian environments. Also, the Town will encourage multi-modal function for all street types (i.e. bus routes & bikes lanes). 1. Ensure Vehicular and Pedestrian Access. The primary function of local streets is to serve abutting properties. Street widths, placement of sidewalks, pedestrian ramps, patterns of streets and number of intersections are related to safe and efficient access to abutting lands. 2. Control Access to Arterials. Local circulation systems and land development patterns should not detract from the efficiency of peripheral arterial facilities. Ideally, land development should occur so that no local streets require direct access to arterial routes. The number of access points between the local circulation system and the arterial system should be minimized. Intersections along arterial routes should be properly spaced for efficient signalization and ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 2 traffic flow. The streets that do intersect the arterial system will tend to have high volumes since they are the only exit points. 3. Discourage Speeding. Residential streets in traditional suburban residential communities should be designed to discourage fast movement (more than 25 mph), through the use of roundabouts and similar traffic control in the street system. 4. Minimize Pedestrian – Vehicular Conflicts. Pedestrian travel from within the area to points outside should require a minimum number of street crossings. Sometimes this may be achieved through proper design of street patterns, land use arrangements and pedestrian routes. Typical methods include use of loop streets, special pedestrian routes or walkways and the proper placement of high pedestrian traffic generators. In general, while vehicular flow must be outward oriented to the peripheral arterials, pedestrian travel should be inward- oriented to avoid these heavier vehicular flows. 5. Appearance of Street Use. Streets should also have an appearance commensurate with their function. They should be in keeping with the residential character, or in the case of downtown streets, in keeping with the character of downtown. 6. Relate Street to Topography. Local streets will be more attractive and economical if they are constructed to closely adhere to topography. The important role that streets play in the overall storm drainage system can be enhanced by using the topography of the area. 7. Lay Out Streets to Achieve Optimum Subdivision of Land. The arrangements of streets should permit economical and practical patterns, shapes and sizes of development parcels. Streets as a function of land use must not unduly hinder the development of land. Distances between streets, numbers of streets and related elements all have a bearing on efficient subdivision of an area. Access to adjoining properties should also be encouraged. 8. Priority Snow Routes. The Town’s Public Works Director will designate priority snow routes within the Town which will receive special consideration in relation to snow removal, parking restrictions, and emergency vehicle access during inclement weather. The Public Works Director may require the placement of signs along these routes. Refer to Monument Town Code Chapter 10 for additional requirements within the Town. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 3 1-2 General This section sets forth the minimum design, technical criteria and specifications to be used in the preparation of all roadway plans. Within this Section on Roadway Design and Technical Criteria, references are made to "A Policy on Geometric Design of Highways and Streets – 2004” as published by the American Association of State Highway and Transportation Officials (AASHTO), commonly known as the “Green Book”. Additionally, standards and details as referenced by the “DCM” refer to “The City of Colorado Springs and El Paso County Drainage Criteria Manual”. Several details and drainage concepts are referenced from this manual and are repeated in this text. Furthermore, the City of Colorado Springs roadway details have been used to supplement the appendices implementing an adaptation of those standards to the Town of Monument standard details. A. Definitions. "Alley" means a strip of land dedicated to public use, located at the side or rear of lots and providing a secondary means of vehicular access to the property. “Average Daily Traffic (ADT)” means the total volume during a given time period (in whole days), greater than one day and less than one year, divided by the number of days in that time period. "Block" means a parcel of land, intended to be used for urban purposes, which is entirely surrounded by public streets, highways, public walks, parks or green strips, rural or vacant land or drainage channels or a combination thereof. "Town” means the incorporated Town of Monument. "Cul-de-sac" means a street having only one end open to traffic and being terminated at the other end by a vehicular turnaround. “DCM” means the El Paso County Drainage Criteria Manual. “Design Limits” is the extent of a project which will be affected by construction activities. “Design Speed” is a selected speed used to determine the various geometric design features of the roadway. "Director" means the Director of Development Services for the Town. "Driveway" means a private access way which is open to the general public, including but not limited to business invitees and patrons of the owner of such access way or such owner's tenant. Driveway does not include private access ways to be used for emergency access and maintenance purposes only, to which access by the general public is prohibited. "Easement" is a right to use the land of another for a specific purpose. “Entry Street” is the closest local street to an arterial. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 4 "Floodplain" means that ground covered by water in the case of the flood of one hundred (100) year frequency as delineated by FEMA flood insurance maps. "Improvements" means street grading, paving and curbing, fire hydrants, water mains, sanitary sewers, storm sewers and drains, pedestrian ways, crosswalks and such other construction as may be designated by the Board. “Inter-District" means travel is through the Town only. “Intra-District" means travel is through the Town and out. “Major Arterial" means serving high-speed and high-volume traffic over long distances. Access is highly controlled with a limited number of full movement intersections and medians with infrequent openings, and no direct parcel access. Adjacent, existing and future, land uses shall be served by other network roadways, service roads, and inter-parcel connections. “Minor Arterial" means serving high-speed and high-volume traffic over medium distances, or anticipated to serve this kind of traffic within a twenty-year period. Access is restricted through prescribed distances between intersections, use of medians, and no full movement parcel access. Minor arterial status is assigned to rural roadways where the probability of significant travel demand in the future is high. “Minor Storm” or “Initial Storm” is the design storm for a five year event. Refer to the El Paso County Drainage Criteria Manual and Section 5 of these standards. “Major Storm” means a design storm for a hundred (100) year event. Refer to the El Paso County Drainage Criteria Manual and Section 5 of these standards. "National Cooperative Soil Survey" means the soil survey conducted by the U.S. Department of Agriculture in cooperation with the State Agriculture Experiment Stations and other federal and state agencies. “PCR” means point of curb return “Posted Speed” is the maximum (or minimum) speed applicable to a section of roadway as established by law and shown on the speed limit sign. "Right-of way" means all streets, roadways, sidewalks, alleys and all other areas reserved for present or future use by the public as a matter of right, for the purpose of vehicular or pedestrian travel. “Snow Route" means all streets and highways designated as a "snow route" as designated by the Town. Refer to Monument Town Code Chapter 10 for additional requirements within the Town. "Street" means a dedicated public right-of-way which provides vehicular and pedestrian access to adjacent properties. This definition includes the terms road, lane, place, avenue, drive and other similar designations. Street, Arterial. "Arterial Street" is the major street in the hierarchy. It has a high ADT and limited access. An arterial provides connections with major state and interstate roadways and has a high potential for the location of ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 5 significant community facilities as well as retail, commercial and industrial facilities. An arterial is intended to take people across town. Street, Boulevard. A “Boulevard Street” is designed to handle traffic volumes loading from and onto local, other collector and arterial roadways. It is intended for use in main access roadways in major subdivisions and regional attractions, and in limited downtown areas. Street, Collector. A "Collector Street" functions to conduct traffic between major arterial streets and/or activity centers. It is a principal traffic artery within residential areas and carries a relatively high volume of traffic. A collector has potential for sustaining minor retail or other commercial establishments along its route which will influence the traffic flow. Street, Lane. A “Lane Street” is designed to provide access to 1+ acre single- family residential properties. Street, Local. A "Local Street" functions to conduct traffic to and from dwelling units to other local or minor collector streets. Street, Nonresidential (Commercial) Collector. A “Commercial Collector” links local roadways and arterial roadways in locations characterized by nonresidential land uses or uncommitted future land uses. Urban nonresidential collectors are intended to accommodate multiple modes of transportation, high-volume turning movements or significant changes in roadway use over time. Urban nonresidential collectors are managed to maximize the safe operation of through-movements. Street, Residential Collector. A “Residential Collector” links local and arterial roadways in exclusively residential areas where build-out conditions for land development and roadway use can be reasonably forecasted. Residential major collectors are managed to maximize the safe operation of through-movements. No full movement parcel access is permitted where the local roadways can be expected to provide access. Where no local public or private roadways can provide access, partial turn movement access may be permitted. "Street Trees" means trees, shrubs, bushes, and all other woody vegetation on land lying between property lines on either side of all streets, avenues, or ways within the Town. Refer to Monument Town Code Chapter 17.52 for additional requirements within the Town. “Subdivision” means the division of a lot, tract or parcel of land into two or more lots, tracts, parcels, or other divisions of land. "Subdivision Improvements Agreement" means one or more security arrangements which may be accepted by the Town to secure the construction of such public improvements as required by the Town and includes collateral, such as, but not limited to, performance or property bonds, private or public escrow agreements, loan commitments, assignments of receivables, liens on property, deposit of certified funds, or other similar surety agreements. “Waiver” is a formal written statement of relinquishment from these standards provided under special conditions by the Town. To acquire a waiver, the developer/property owner must provide the Town with a letter of ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 6 explanation as to why the waiver is required with an explanation of specific circumstances that render the particular code provision ineffective. In addition, the letter of explanation shall also provide proof that the suggested alternative will maintain public safety and prove that the intent of the Town standard is being satisfied. Waivers are granted administratively. B. Warranty Periods. The warranty period for streets, curbs, gutters, sidewalks, utilities, drainage and all other appurtenances, shall be two years from the date of initial acceptance. Public improvements will not be deemed to have been finally accepted until all necessary remedial work has been completed to the satisfaction of the Director of Development Services and no warranty period will expire until such final acceptance, notwithstanding the fact that such period would have otherwise expired by the passage of time. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 7 1-3 Roadway Design and Technical Criteria The following criteria are listed in tabular form on tables in Appendix A. Table 5.8 shows a summary of the minimum roadway construction requirements and other related information. These principles are not intended as absolute criteria, since instances may appear where certain principles conflict. The principles should, therefore, be used as guides to proper systems layout. These criteria will be used for future roadway design and existing roadways will be exempt from the following criteria. Roundabouts are an acceptable means of traffic control; refer to Appendix C Figures DT-26 and DT-27 for roundabout design and signage requirements. Street and stop signs shall be placed as needed to ensure adequate traffic control. Refer to Appendix C DT-34 for street signage requirements and DT-35 for stop sign requirements.

Roadway typical sections shall be as specified by these Roadway Standards. They are summarized in Appendix B, Details 1 to 11c of these Standards. B. Sidewalks 1. General. Sidewalks shall be constructed on both sides of all roadways unless specifically approved otherwise by the Town of Monument. All sidewalks shall be installed by the developer at the time of road and/or curb and gutter installation. Sidewalks may be installed in phases in residential neighborhoods, with phasing to be consistent with the construction of homes within a particular block or section. No utilities shall be placed under sidewalks. A drain pipe may be placed under the sidewalk in accordance with Detail DT-20 in Appendix C. Refer to Appendix C for sidewalk passing space requirements and sidewalk pedestrian clearance zone requirements as shown in Details DT-05 and DT-21 respectively. Developer shall have the choice either to complete all subdivision sidewalks before home construction begins or to build sidewalks concurrently with individual home construction. If sidewalks are to be built before home construction, the sidewalk security shall be included in the SPIA Security. If the sidewalks are to be built concurrently with the homes, the Developer shall provide Security in the form of cash that will be placed into an escrow account with the Town. The amount of the guarantee shall equal 125% of the estimated construction cost of the sidewalks, as provided in Exhibit A, Section A3 of the SPIA. As sidewalks are completed and approved, the Town will refund monies based on the unit cost, provided in Exhibit A, Section A3 of the SPIA. The Town shall be entitled to draw upon the Security in the event of a default by Developer in completing the sidewalks. The purpose of the Security is to provide the Town with the financial resources to mitigate any public health and safety hazards by completing construction of all sidewalks should Developer default in its obligation to complete the improvements, or if build-out of the subdivision, or particular phase of the subdivision, takes longer than originally anticipated. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 40 In order to ensure safety for pedestrians, the Town shall require all sidewalks to be completed along an individual block when any one of the following conditions has been met:  If construction activities have not taken place for at least 180 consecutive days.  On blocks with 20 or more lots, when no more than 50% of the available lots have been completed.  On blocks with less than 20 lots, when no more than 25% of the available lots have been completed. Sidewalks shall be four inches in thickness and a minimum of five feet in width. Sidewalks shall have a minimum thickness of six inches at all residential driveways and eight inches at all commercial driveways for the full width of the driveway approaches. Sidewalks shall have a minimum slope of one quarter inch per foot toward the top of the curb. Maximum slump for all concrete shall be with a compressive strength of 4000 psi at 28 days. Concrete for construction of sidewalks and pedestrian ramps shall be as specified in Sections 502 through 508 of the Colorado Springs Standard Specifications Manual, with the exception that the maximum size for aggregate shall be three-quarter inch rock.(ASTM C-33, Size No. 67). 1. Preparation of Subgrade. Before the placement of concrete, the area under the section shall be graded and compacted to not less than: a. For cohesive soils, 90% of Modified Proctor at of optimum moisture content, or 95% of Standard Proctor at of optimum moisture content b. For noncohesive soils, 92% of Modified Proctor at of optimum moisture content, or 97% of Standard Proctor at of optimum moisture content. c. For expansive soils, 88% of Modified Proctor at 3% above optimum moisture content or 93% of Standard Proctor at 1% above optimum moisture content. 3. Expansion Joints. Expansion joints shall be one-half inch premolded polyurethane joint material. Joints shall be placed where sidewalks end at curb returns, against fixed objects, at points of sharp radius, and between sidewalks and all driveway slabs. Expansion joints shall be placed a maximum of every fifty (50) feet. 4. Contraction Joints. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 41 Contraction joints shall be installed at intervals not to exceed five feet and shall be at least one and one-half inches in depth. 5. Placement and Finish. In depositing concrete against the forms, care shall be taken to work the fine portions of the aggregate surface so as to leave the surface in a uniform and smooth condition. The concrete shall be worked sufficiently to produce a dense mass. The surface shall be struck off with a straight- edge. When the concrete has set sufficiently, the surface shall first be trowelled, then broomed with a fine hair push broom at right angles to the centerline of the sidewalk. Pedestrian ramps shall be broomed with a coarse hair push broom, parallel with the scoring. C. Handicap Ramps. State law requires that handicap ramps be installed at all intersections and at mid-block locations specified by the Town for all new construction or reconstruction of curb and sidewalk. Handicap ramps shall be constructed in accordance with Details DT-06 through DT-16 in Appendix C. Handicap ramps may be shown at all curb returns or called out by a general note on the development plans, but must be shown (located) at all intersections directly opposite either curb return. D. Curb Returns Radii. See Appendix - Table 5.2 for curb return radii. E. Curb Cuts. Curb cuts and driveways shall be constructed in accordance with Detail DT-22 in Appendix C. F. Mailboxes. The local branch of the United States Postal Service has the final decision on size and location of mailboxes and mailbox groupings. G. Policy Regarding Damage. Any damage to public infrastructure as a result of vegetation growing on an adjacent property is the responsibility of the adjacent property owner. H. Sidewalks and Gutters Clear. It is unlawful for any person performing any excavation to place any dirt, debris, or other materials upon any sidewalk or in any gutters. Such work shall be performed so as to permit the free passage of water along the gutters. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 42 1-5 Horizontal Alignment A. Horizontal Curves. Minimum curve radii shall be as shown in Appendix A - Table 5.1. B. Curb Return Radii. Minimum and maximum curb return radii shall be as shown in Appendix A - Table 5.2. C. Design Speed. Horizontal alignment design speed shall be consistent with the requirement for vertical alignment design speed. If no superelevation is required and a normal crown section exists, the horizontal curve data as shown in Appendix A - Table 5.1 shall be used. D. Superelevation. Superelevation may be required for curves on arterial roadways and selected collector roadways. Horizontal curve radii and superelevation shall be in accordance with the recommendations of the AASHTO "Green Book," (Horizontal Alignment). Superelevation shall not be used without prior approval by the Town. Superelevation shall not be used on local or other roadway classifications with a design speed of less than 50 mph. The following procedure is an outline for the correct application of superelevation on roadways: 1. Definitions Regarding Superelevation. Superelevation Runoff: Superelevation runoff is that length of roadway needed to accomplish the change in cross slope from a section with the adverse crown removed (flat) to the fully superelevated section, or vice versa. Transition Points: Beginning or ending of tangent runout, superelevation runoff or full superelevation. Tangent Runout: The length of roadway needed to accomplish the change in cross slope from a normal crown section to a section with the adverse crown removed (flat), or vice versa. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 43 2. Standards for Superelevation. The CDOT Standards on Superelevation give the required rate of superelevation for the various degrees of curvature. The maximum superelevation rate is 0.04 feet per foot. 3. Urban Street Conditions. Every effort should be made to maintain standard rates of superelevation. However, in urban areas, street intersections, established street grades, curbs, and drainage conditions may require a reduction in the rate of superelevation, or different rates for each half of the roadbed. In warping areas for drainage, adverse superelevations should be avoided. E. Spiral Curves. Spiral curves shall not be used. F. Cul-de-sacs. Cul-de-sacs shall have a minimum flowline radius of forty-five (45) feet. Refer to the International Fire Code for multi-family units. See Appendix C - Detail DT-28 for cul-de-sac requirements. G. Sight Distances. 1. General. The major considerations in alignment design are safety, grade, profile, road area, design speed, sight distance, topography, drainage and performance of heavy duty vehicles. Alignment should provide for safe and continuous operation at a uniform design speed. Road layout shall bear a logical relationship to existing or platted roads in adjacent properties. 2. Horizontal Alignment. Sight Distance. Horizontal alignment must provide at least the minimum stopping distance for the design speed at all points. This includes visibility at intersections as well as around curves and roadside encroachments. Stopping Sight Distance. The minimum stopping sight distance is the distance required by the driver of a vehicle traveling at the design speed to bring the vehicle to a stop after an object on the road becomes visible. Object height shall be 2’ above road surface and viewer’s height shall be considered to be 3.50 ft. above road surface. See Appendix A Tables 5.4 – 5.6 for stopping sight distance requirements. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 44 Where an object off the pavement restricts sight distance, the minimum radius of curvature is determined by the stopping sight distance (see Appendix A – Tables 5.4 – 5.6). In no case shall the stopping sight distance be less than as specified in Appendix A - Table 5.4. A likely obstruction may be a bridge abutment or line of columns, wall, cut side slope, or a side or corner of a building. The sight distance design procedure shall assume a 6'-0" fence (as measured from actual finished grade) exists at all property lines except in the sight distance triangles required at all intersections. The horizontal sight restrictions may occur where there is a cut slope on the inside of the curve. For the 3.5-foot eye height and the 2-foot object height used for the stopping sight distance, a height of 2.75 feet may be used as the midpoint of the sight line where the cut slope usually obstructs sight. This assumes that there is little or no vertical curvature. Passing Sight Distance. Passing sight distance is the minimum sight distance that must be available to enable the driver of one vehicle to pass another safely and comfortably without interfering with oncoming traffic traveling at the design speed. Two-lane roads should provide adequate passing zones. Required passing sight distance for given design speeds is given in Appendix A - Table 5.4. Intersection and Driveway Sight Distance (Sight Triangle). There shall be an unobstructed sight distance along both approaches of both sides at an intersection within the right-of-way for distances sufficient to allow the operators of vehicles, approaching simultaneously, to see each other in time to prevent collisions at the intersection. The sight triangle relationship developed for use in the Town of Monument is based upon the dimensions shown in Appendix A – Table 5.4 and Figure DT-25. Any object within the sight triangle which is more than thirty-six (36) inches above the flowline elevation of the adjacent street shall constitute a sight obstruction and shall be removed or lowered. Such objects include: buildings, cut slopes, hedges, trees, bushes, utility cabinets or tall crops. This design criteria also requires the elimination of parking (except on local streets) within the sight triangle and applies whether the intersecting roads are level or on grades. The sight distance shall be measured to the centerline of the closest through lane in both directions. All sight distance triangles must be within the public right-of-way or a sight distance easement will be required (refer to Appendix A – Table 5.4 and Figure DT-25). A sight distance easement shall be required if the line of sight crosses onto private property. The sight ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 45 distance easement or necessary right-of-way shall be dedicated to the Town to provide the required sight distance. Maintenance of a sight distance easement shall be the responsibility of the property owner or the homeowners’ association unless otherwise approved by the Town. All sight distance triangles must be shown on the street plan/profile plans. In no case shall any permanent object encroach into the line-of-sight of any part of the sight distance triangle. Where there is downtown redevelopment, the sight distances shall be reviewed and approved by Town staff on a case by case basis. However, every effort shall be made to meet the criteria in this section. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 46 1-6 Vertical Alignment A. Design Controls. Design controls for vertical alignment are shown in Appendix A - Figures A-1 & A- 2. B. Permissible Roadway Grades. See Appendix A - Table 5.3. C. Sight Distances. Both the horizontal and vertical sight distance should be checked to insure that the sight distance along the major highway is sufficient to allow a vehicle to cross or turn left, whichever is required. By determining graphically the sight distances on the plans and recording them at frequent intervals, the designer can appraise the overall layout and affect a more balanced design by minor adjustments in the plan or profile. See Figure DT-25 for a typical sight distance record that would be shown on the final plans. Because the view of the highway ahead may change rapidly in a short distance, it is desirable to measure and record sight distance for both directions of travel at each station. Both horizontal and vertical sight distances should be measured and the shorter recorded. In the case of two-lane streets, passing sight distance in addition to stopping sight distance should be measured and recorded. Once the horizontal and vertical alignments are tentatively established, the practical means of examining sight distances along the proposed street is by the method demonstrated in Figure DT-25. Horizontal sight distance on the inside of a curve is limited by obstructions such as buildings, hedges, wooded areas, high ground, or other topographical features. These generally are plotted on the plans. The cut slope obstruction is shown on the worksheets by a line representing the proposed excavation slope at a point 2.0 ft. (average of 3.50 and 0.5 ft) above the road surface for stopping sight distance and at a point about 3.75 ft. above the road surface for passing sight distance. The stopping sight distance should be measured between points on the one traffic lane, and passing sight distance from the middle of one lane to the middle of the other lane as detailed in Figure DT-25 of Appendix C. A simple sight distance record is shown in Appendix C - Figure DT- 25. Sight distances in both directions are indicated by arrows and figures at each station on the plan and profile sheet of the proposed ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 47 roadway. To avoid the extra work of measuring unusually long sight distances that may occasionally be found, a selected maximum value may be recorded. In the example shown, all sight distances of more than 3,000 ft. are recorded as 3,000+, and where this occurs for several consecutive stations, the intermediate values are omitted. Sight distances less than 1,000 ft. may be scaled to the nearest 50 ft. and those greater than 1,000 ft. to the nearest 100 ft. D. Permissible Intersection Grades (Public Rights of Way). The maximum permissible grade at intersections will be as shown in Appendix A – Table 5.3. These grades are maximum instantaneous flowline grades for the stated distances (each side of the street) for the minor (intersecting) street. All private commercial driveways with curb return radii shall follow the standard set forth for a local street. The length of the maximum grade for the commercial driveway shall begin at a minimum of 50 feet measured from the flowline where the driveway intersects the public roadway. The maximum grade for a residential drive is 10%. A waiver may be requested to increase the grade to 14%. The maximum grade for arterial intersections is A waiver may be requested to increase the grade. E. Changing Grades. The use of grade breaks in lieu of vertical curves is discouraged. However, if a grade break is necessary and the algebraic difference in grade does not exceed five tenths of a percent (0.005 ft./ft.) along the roadway, the grade break will be permitted. The maximum grade break allowed at the point of tangency at a curb return for local and collector roads shall be two (2.0) percent and for arterial roadways a maximum of one (1.0) percent for all other roadway classifications. F. Cross Fall. Except at intersections, or where superelevation is required, roadways shall be level from top of curb to top of curb (or flowline to flowline). The distance from intersections with which 'cross-fall' will be permitted shall be determined by criteria in Section 1-17.D, Cross-Slope. G. Vertical Curves. When the algebraic difference in grade is at or exceeds the maximum values, a vertical curve is to be used. Design criteria for vertical curves are found in Appendix A – Figures A-1 and A-2 of these Standards. The minimum gradients into and out of a sag (sump) vertical curve is five-tenths of a percent (0.005 ft./ft.). Minimum length of a vertical curve is shown in Section 1-6A of these Standards. All vertical curves shall be labeled, in the profile, with length of curve and K= (L/A) values, where is defined as the algebraic difference in approaching slopes. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 48 H. Vertical Clearance. A minimum vertical clearance of 13 feet 6 inches will be maintained at all times. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 49 1-7 Intersections A. Design Criteria. The following criteria shall apply at intersections: 1. Grade. The grade of the "through" street shall take precedence at intersections. At intersections of roadways with the same classification, the more important roadway, as determined by the Town, shall have this precedence. The design should warp side streets to match through streets with as short a transition as possible. 2. PCR of the Curb Return. The elevation at the PCR of the curb return on the through street is always set by the grade of the through street in conjunction with normal pavement cross slope 3. Crown & Elevation. Carrying the crown at a side street into the through street is permitted only when drainage considerations warrant such a design. Refer to Section 1- 17D for street cross slope allowances. The key criteria for determining the elevation of the curb return on the side street and the amount of warp needed on a side street transitioning to a through street are: Permissible grade. See Appendix A - Table 5.3. Vertical controls within the curb return itself. (See Section 1-6). 4. Dipping the Flowline. Dipping the flowline to the extent that the lip of gutter is also dipped will not be permitted. Inlets shall be placed such that the flow line of the inlet and the flow lines of the gutter upstream and shall be continuous and at the same grade. 5. Arterial-Arterial Intersections. A more detailed review shall be performed for arterial-arterial intersections to maximize driveability. Few arterial intersections will have a uniform 2% cross slope, the majority of them having one or more sides warped. (See Section 1-7, B-4 of these Standards for rates of pavement warp allowed). 6. Intersection Angle. Whenever possible, intersections shall be made at right angles or radial to a curve. No intersecting angle of less than eighty (80°) degrees will be allowed. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 50 7. Curb Returns. All curb returns must drain. No inlets are allowed within a curb return. Inlets can be placed at the PT or PC of a curb return. B. Curb Return Profiles Curb return profiles are required for radii equal to or greater than thirty (30) feet within the public right-of-way. A midpoint elevation along the arc length of the curb return shall be shown in plan view for radii equal to or greater than twenty- five (25) feet. Curb return design shall be set in accordance with the following design procedure. General standards for flowline control and profiles within the curb returns shall be as follows: 1. Point of Tangency. The point of tangency at each curb return shall be determined by the projected tangent grade beginning at the point of intersection of the flowlines. 2. Arc Length and External Distance. The arc length and external distance of the curb return shall be computed and indicated on the drawing. 3. Flowline Grade. Show the corresponding flowline (or top of curb) grade for each roadway beyond the P.C.R. 4. Flowline Slope. Design the flowline of the curb return such that the maximum slope along the flowline does not exceed eight percent. Grade breaks at the PCR's will not exceed two percent for local and collector streets and one percent for arterials. Minimum curb & gutter grade is 0.5%. No more than 1' vertical difference in elevation across the street at the PCR is allowed. 5. Scale. Scale for the curb return profile shall be 1" = 20' horizontally and 1" = 4' vertically, unless otherwise approved by the Town. 6. Curb Return Radii. Curb return radii, existing and proposed, shall be shown. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 51 C. Connection with Existing Roadways. 1. Vertical Curve. Connections with existing roadways shall be smooth transitions conforming to normal vertical curve criteria (See Section 1-6). If the algebraic difference in grade between the existing and proposed grade exceeds the maximum allowed, a vertical curve is used to make this transition. The vertical curve shall be fully accomplished prior to the connection with the existing improvement and shall also comply with the grade requirements at intersection approaches. 2. Existing Grade. Existing grade shall be shown for at least two-hundred (200) feet with field verified as-builts showing stations and elevations at twenty-five (25) foot intervals. In the case of connection with an existing intersection, these as-builts are to be shown within a two-hundred (200) foot radius of the intersection. This information will be included in the plan and profile that shows that proposed roadway. Limits and characteristics of the existing improvement are the primary concern in the plan view. Such characteristics include horizontal alignment, off-site intersections, limits of the improvement, etc. 3. Approved Design for Existing Improvements. Previously approved designs for the existing improvements are not an acceptable means of establishing existing grades; however, they are to be referenced on the construction plan where they occur. 4. As-Built Elevations. The basis of the as-built elevations shall be the same as the design elevations (both flowlines or both tops of curb, etc.,) when possible. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 52 1-8 Phased Design The design grade and existing ground at that design grade, all of the roadways that dead end due to project phasing, subdivision boundaries, etc., shall be continued in the same plan and profile as the proposed design for at least five hundred (500) feet or to its intersection with an arterial roadway. This limit shall be extended to one thousand (1,000) feet when arterial roadways are being designed. If the off-site roadway adjacent to the proposed development is not fully improved, the developer is responsible for the design and construction of a transition for the safe conveyance of traffic from his improved section to the existing roadway. The following formula shall be applied to determine the length of the taper of lane change necessary for this transition: L = WS2/60 where L = Length of transition in feet W = Width of offset in feet S = Speed limit or 85th percentile speed ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 53 1-9 Acceleration/Deceleration Lanes The design of the arterial street system depends upon the proper control of access to developments. The location and design of access points must minimize traffic hazards and interference with through traffic movements. Acceleration/Deceleration lanes shall be designed using CDOT Access Codes, refer to the State of Colorado website2. The need for acceleration or deceleration lanes shall be established by the (different) approved traffic impact study, which should follow the Town of Monument criteria. The approved traffic impact study will be completed for the final plat or final development plan. 2 CDOT Access Codes on the State of Colorado Website: http://www.dot.state.co.us/AccessPermits/PDF/601_1_AccessCode_March2002_.pdf ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 54 1-10 Construction Traffic Control A. Pedestrian Traffic. 1. General. Every precaution shall be taken to ensure that construction work does not interfere with the movement of pedestrian traffic, which shall be maintained on the sidewalk at all times. Flagperson(s) shall be provided for guidance as necessary. 2. Sidewalk Interruption. Where an excavation interrupts the continuity of the sidewalk, the contractor shall provide suitable bridge or deck facilities, to be supplemented by the use of such proper devices and measures as prescribed in the Manual on Uniform Traffic Control Devices, most recent edition, for the safe and uninterrupted movement of pedestrian traffic. The edges or ends of the pedestrian bridge or decking shall be beveled or chamfered to a thin edge to prevent tripping. 3. Temporary Diversion Walkways. Temporary diversion walkways shall be hard surfaced and electric lighting shall be provided and kept continuously illuminated during hours of darkness, when required by the Town. 4. Pedestrian Detours in Roadway. Unless otherwise authorized by the Town, pedestrians shall not be channeled to walk on the traveled portion of a roadway. 5. Pedestrian Detours Across Street. Under certain conditions, it may be necessary to divert pedestrians to the sidewalk on the opposite side of the street. Such crossings shall only be made at intersections or marked pedestrian crossovers. 6. Pedestrian Crossings. Facilities satisfactory to the Town shall be provided for pedestrian crossings at corners, pedestrian crossovers and public transportation stops. B. Vehicular Traffic. 1. Construction Work Zone Traffic. Construction work zone traffic shall be controlled by signs, barricades, detours, etc., which are designed and installed in accordance with the Manual on Uniform Traffic Control Devices, most recent edition. A traffic control plan prepared by a certified traffic control supervisor shall be submitted and approved by the Town of Monument Director of Development Services or designee prior to start of any construction. A ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 55 maintenance of traffic permit must also be acquired from the Town prior to construction. 2. Construction of New Facilities. During construction of new facilities, traffic control should strive to keep the motorist from entering the facility. The primary means to accomplish this are by use of temporary barricades, located in advance of the point where new construction joins existing and by appropriate signing. New construction shall not be opened to traffic, and thus the construction traffic control removed, without the approval of the Town. 3. Construction Traffic Control Plan - General. In general terms, a construction traffic control plan must be drawn on a map. For minor projects or local roadways, a neat sketch of the roadways and the proposed control devices will suffice. For major projects or major roadways, the traffic control plan should be superimposed on as-builts, construction plan drawings, or other detailed maps. 4. Construction Traffic Control Plan – Design. The Manual on Uniform Traffic Control Devices (MUTCD) shall be the basis upon which the construction traffic control plan is designed, in concert with proper, prudent, and safe engineering practice. All necessary signing, striping, channelization devices, barricading, flagging, etc. shall be shown on the plan. 5. Barricades. Whenever roadways terminate due to project phasing, subdivision boundaries, etc., barricades are required. Design and construction shall comply with the requirements of the MUTCD, most recent edition. Details shall be shown on the construction drawings and installation shall be provided by the developer.

See Detail 40 in Appendix C for traffic signal detail. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 66 1-13 Basic Principles for Curb Openings and Driveways A. General. Certain control values for curb openings and driveways require minimum dimensions in some instances and maximum values for other dimensions. The design of curb openings and driveways within the range of these dimensions will provide for good service on the part of the motorist using the driveway while at the same time minimizing interference to the traffic using the street. By controlling the location and width of openings or driveways along the street, it will be possible to avoid or eliminate long open stretches where motorists can indiscriminately drive onto the street. The widths of openings established in these Design Standards are based on studies which indicate that the various width openings will accommodate vehicles of maximum size authorized on Town streets and highways. In case of conflict between requirements in the various sections of this chapter, the more restrictive condition will normally apply. The opening or driveway width should be adequate to properly handle the anticipated traffic volume and character of traffic, as well as being within the limits specified for the type of property development. The controls established for curb openings and driveways shall apply to existing streets as well as new streets that may be developed in the future. Details for driveway standards with attached and detached sidewalks are shown in Appendix C – Detail DT-03 and DT-04. To the greatest extent possible all openings for driveways shall be located at the point of optimum sight distance along the street. For openings and driveways to commercial establishments and service stations there shall be sufficient space reasonably cleared of any obstructions such that drivers entering the property will have sufficient sight distance to enable them to make proper and safe movements. The profile of a driveway approach and the grading of the adjacent area shall be such that when a vehicle is located on the driveway outside the traveled portion of the street the driver can see a sufficient distance in both directions so as to enable him to enter the street without creating a hazardous traffic situation. The driveway profile grade within public R.O.W. shall not exceed two percent for collector and arterial streets and four percent for local streets. Any adjustments which must be made to utility poles, street light standards, fire hydrants, catch basins or intakes, traffic signs and signals, or other public improvements or installations which are necessary as the result of the curb openings or driveways shall be accomplished without any cost to the Town. Also, any curb opening or driveway which has been abandoned shall be restored by the property owner except where such abandonment has been made at the request of, or for the convenience of, the Town. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 67 Driveway approaches, whereby the driveway is to serve as an entrance only or as an exit only, shall be appropriately signed by, and at the expense of, the property owner. The property owner will be required to provide some means of ensuring that the motorists will use the driveway either as an entrance only or an exit only, but not both. All common areas and parking lot access drives shall have a maximum grade of B. Paving. All access ways between a public street and off-street parking spaces or areas, and all off-street parking spaces, driveways and aisles shall be surfaced with asphalt or concrete. C. Corner Clearance It is important to locate driveways away from major intersections. This constraint is as much for the ability to enter and leave the property as for the benefit of intersection safety and operations. Exiting a driveway during peak- hour conditions at traffic signals is difficult where the queue of standing or slow-moving vehicles never allows a sufficient gap for entry from the driveway. Corner clearances are measured from the curb line. D. Sight Distance Sight distance for curb openings to private property shall consist of a sight triangle conforming to the requirements of Section 1-5.G.2 of these standards. This does not apply to driveways in single-family residential projects using mountable curb, gutter, and sidewalks. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 68 1-14 Standard Construction Specifications Standard construction specifications for roadways, grading and drainage construction within the Town shall be the Colorado Department of Transportation "Standard Specifications for Road and Bridge Construction," latest edition. A. Detailed Construction Specifications. The Detailed Specifications for a specific project within the Town shall consist of the applicable sections and subsections numbered Section 200 through Section 700 of the above-referenced "Standard Construction Specifications", Triview Metropolitan District Design Criteria and Construction Specifications Manual Standard Details and/or the DCM, whichever is more stringent. Special project provisions pertaining to a specific project take precedence over Specifications or Plans, and supplement or amend the referenced "Standard Specifications for Road and Bridge Construction" latest edition, by the Colorado Department of Transportation, which is to be used to control construction of the project. References to "Division" or "DOT" in the Standard Specifications shall be considered to mean the Town of Monument. B. Standard Construction Details It is the intent of the Town to use applicable details from the CDOT Division of Highways M&S Standards, latest edition. Drainage-related appurtenances shall be constructed per the Triview Metropolitan District Design Criteria and Construction Specifications Manual Standard Details and/or the DCM, whichever is more stringent. Applicable details shall be as noted on the plans for a specific project. C. Specific Details a. Disturbance to existing trees shall be restricted and considered by the Town on a case-by-case basis. In the event that the tree shall be protected, refer to Appendix C, Detail DT-18 for tree root protection. If tree root cutting is required, refer to Detail DT-19 in Appendix C. b. Concrete expansion joints and concrete paving requirements and details shall be in accordance with Appendix C, details DT-23 and DT-24. c. In the event that pavement shall be replaced, refer to detail DT-43 in Appendix C for requirements. d. For general utility requirements, including water, sanitary sewer and storm sewer facilities, refer to Appendix C, details DT-36 through DT-39 for standards and requirements. Any utilities placed in public right-of-way shall adhere to these Standards. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 69 1-15 Work Within Public Right-of-Way The El Paso County Department of Transportation ECM (Engineering Criteria Manual) dated 1/9/2006, Chapter 4: Utilities and Other Right-of-Way Uses has been adopted by the Town of Monument for work to be accomplished within the public right-of-way. This regulation should be referred to for the specific requirements for cutting and repairing Town streets and for pertinent information about backfilling trenches. No person shall make any excavation or fill in any public street or alley, gravel or paved, without first obtaining a permit for the work from the Town. Permits for work in rights-of-way within the Town boundaries must be obtained from the Town of Monument Development Services Department. Permit applications may be obtained at Town Hall. Any access, driveway, or curb-cut which is constructed within public right-of-way without an access permit issued by the Town shall be subject to “STOP Work” order and shall be removed immediately. Failure to remove the unpermitted access may result in the removal of said access by the Town (the cost for removal shall be charged to the property owner from which the access originates). Failure to obey the “Stop Work” order may result in the prosecution of the violators. For work within the Town boundaries, a bond or letter of credit with automatic renewal for one hundred and twenty-five percent (125%) of the contracted cost of construction within the right-of-way is required to be submitted, along with a copy of the contract for construction. If this information is not available, an engineer’s estimated cost of construction may be substituted. A copy of the contractor’s certificate of insurance must be submitted or be on file with the Town prior to issuance of a permit for work within the right-of-way. The policy must have minimum limits of $1,000,000 combined single limit coverage for bodily injury and property damage liability and shall name the Town of Monument as an additional insured party. In addition, the contactor shall hold the Town harmless from any claims resulting from, or relating to, the work. Warranties for complete work within Town right-of-way shall be pursuant to the El Paso County Department of Transportation (ECM) Chapter 5, Section 5.3.15- Construction Surety, Warranties, and Acceptance of Public Improvements. Any street that has been paved or overlain within the previous three years cannot be cut, except for emergency repairs, without the written approval of the Town. If such written approval is obtained, special backfill requirements shall be per the Standard Roadway Detail DT-17, as shown in Appendix C, or as may otherwise be required. Compaction tests shall be performed on all trench backfill in accordance with Triview Metropolitan District Standards and Specifications - see Water and ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 70 Wastewater Excavation and Trenching (Sections 7.3 and 8.6, respectively). Additional tests may be required at the discretion of the Town. Existing pavement and base course thickness shall be matched with permanent paving and base repairs as a minimum. Any special design must be approved by the Town. Temporary patching with a minimum of 2 inches of bituminous hot or cold mix may be installed subject to the approval of the Town, and must be maintained in a safe, drivable condition by the contractor until weather permits permanent pavement construction. In the case of a failure of an excavation repair, the contractor shall have two hours after notification to begin emergency repairs or barricading. If the contractor fails to comply, the Town may perform the work and will bill the contractor for the cost thereof, along with any additional charges per Chapter 5 of the El Paso County Engineering Criteria Manual (ECM) adopted on 1/9/2006. The costs associated will be billed to the applicant and must be paid within 30 days from the date of billing. Each applicant shall be responsible for the cost of repairing any facilities in the right-of-way which it or its facilities damage. If the defective work is not corrected by the permit holder, and the Town does the work and sends a bill to the permit holder, who fails to pay for such work, the Town may exercise its rights under the defect warranty. The following are exempt from having to file a defect warranty: special districts, utilities governed by the State Public Utilities Commission, and municipalities. ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 71 1-16 Roadway Drainage A. General. As specified in Section 4 of the Triview Metropolitan District Standards for Storm Drainage and Erosion Control, minor and major storm drainage systems must be designed in accordance with the City of Colorado Springs/El Paso County Drainage Criteria Manual (DCM), latest edition. Because safe and efficient conveyance of traffic is the primary function of roadways, the storm drainage function of the roadway (such as allowable gutter capacity and street overtopping) will be designed to the limits set forth herein. In the case of a conflict caused by requirements of the City of Colorado Springs/El Paso County Drainage Criteria Manual, the more stringent criteria shall apply. B. Crosspans. Crosspans are not permitted across major collector roadways or arterial roadways. Crosspans are recommended at cross streets unless there is reason to believe that the intersection will eventually be signalized. Crosspans located anywhere other than street intersections or at entry streets will require the granting of a waiver. See Appendix C - Detail DT-02 for crosspan requirements. The use of any crosspan on roadways where the vertical grade exceeds four and one-half percent at the crosspan will be considered only after all other alternatives have been determined to be impractical. C. Storm Sewer Inlets. Inlets shall be located to intercept the curb flow at the point curb flow capacity is exceeded by the storm runoff. Inlets shall also be installed to intercept cross pavement flows at points of transition in superelevation. Inlets are not allowed in the curb return except with Town approval. Inlets will be located at or behind the tangent points of the curb returns. Minimum inlet length for type R inlets shall be 5 feet. D. Cross Slope. Except at intersections, or where superelevation is required, roadways shall have a two percent crown from the high point of the road cross-section to each flowline. Top of curb elevations on both sides of the street shall be identical. 1. Parabolic or Curved Crowns. Parabolic or curved crowns are not allowed. In no case shall the pavement cross slope at warped intersections exceed the grade of the through street. 2. Cross Slope. The rate of change in pavement cross slope, when warping side streets at intersections, shall not exceed one percent every twenty-five (25) feet horizontally on a local roadway, one percent every forty (40) feet ---PAGE BREAK--- PAVEMENT DESIGN AND CONSTRUCTION STANDARDS Page I 72 horizontally on a collector roadway, or one percent every sixty (60) feet horizontally on an arterial roadway. E. Temporary Erosion Control. Temporary erosion control is required along and at the ends of all roadways that are not completed due to project phasing, subdivision boundaries, etc. Refer to the Monument Municipal Code, Sections 8.30 and 16.40, for additional requirements. F. Sidewalk Chases. Storm water from concentrated points of discharge shall not be allowed to flow over sidewalks, but shall drain to the roadway by use of chase sections. Sidewalk chase sections shall not be located within a curb cut or driveway. Hydraulic design shall be in accordance with the DCM, Section III Design Methods, Chapter 6 – Design Criteria and Chapter 7 – Street Drainage & Storm Water Inlets. G. Storm Water Conveyance in Streets. The design criteria for stormwater conveyance in public streets are based on a reasonable frequency of traffic and pedestrian interference. The engineer/designer should recognize that the primary purpose of streets is for traffic, and therefore the use of streets for storm runoff must be restricted. See Appendix D, Table 1 for the allowable capacity for storm runoff in the streets. The Town allows the use of roads and streets for drainage.
