SECTION 9 VARIANCES When a subdivider can show that a provision of these regulations would cause unnecessary hardship if strictly adhered to and where, because of some condition peculiar to the site, in the opinion of the City Council a departure may be made without destroying the intent of such • provisions, the City Council may authorize a variance. The council shall consider the nature of the proposed usage of land involved, the existing usage of land in the vicinity, the number of persons who will reside or work in the proposed subdivision, and the probable effect of a such variance on traffic conditions and public health, safety, convenience, and welfare of individuals in the vicinity. No variances will be granted unless the council finds the following: 4� (a) There are special circumstances or conditions affecting the land involved such that the strict application of the provisions of the ordinance would deprive the applicant of the reasonable use of his land. (b) The variances are necessary for the preservation and enjoyment of a substantial property right of the applicant and the granting of the variance will not be detrimental to the public health, safety, or welfare of individuals, or injurious to other properties in the area. (c) The granting of the variance will not have the effect of preventing the orderly subdivision of other lands in the area in accordance with the provisions of this ordinance. Pecuniary hardship to the subdivider, standing alone, shall not be deemed to constitute undue hardship. Any variance thus authorized is required to be entered in writing into the minutes of the Commission and/or the City Council and the reason which justified the departure to be set forth, and such variance must be authorized by affirmative vote of not less than two-thirds (2/3) of the entire members of the City Council, 34 1-25-2000 SECTION 10 PENALTY Any person violating this ordinance or any portion thereof shall upon conviction be guilty of a misdemeanor and shall be fined any sum not exceeding one thousand dollars ($1,000.00) and each day that such violation continues shall be considered a separate offense and punishable accordingly.

The purpose of this section is to provide a set of minimum design standards to be used in the designing of roadway facilities in the City of Anna. These guidelines will be used by consultants employed by the city and engineers for private developments in the city. Each sheet of the plans and profiles will bear the seal and signature of the registered professional civil engineer who prepared them. These guidelines should result in the construction of safe, economical streets and thoroughfares. The City Council may approve unusual circumstances or special designs requiring a variance from the standards in this manual. Classification of Roadways There are four (4) basic classifications of streets in the City of Anna. The classifications are as follows: Principal Arterial seven (7) lane divided and undivided This classification is designed to handle large volumes of intra- and inter -city travel through Anna. No direct residential driveway access should be allowed (at least on new sections where driveways do not presently exist). Minor Arterial five (5) lane divided and undivided and Minor Arterial four (4) lane undivided This classification is designed to feed traffic from collectors and minor residential streets the Principal Arterial. Direct residential driveway access should not be allowed on new sections of arterial except where existing driveways are present. Collector two (2) lane undivided Collector streets should direct residential and local traffic onto the nearest arterial to avoid carrying volumes of through -traffic across residential neighborhoods and other sensitive areas. Direct residential driveway access is permitted. The Collector street shall be the minimum street class serving commercial, industrial or multifamily areas. Residential two (2) lane undivided The minor residential is to provide access to the various residential classifications in the City of Anna. Each roadway is made up of elements that are related to the use of that particular facility.

Included in the geometrics are the pavement, width, radius of curvature, width of traffic lanes, parking lanes, or turning lanes, median width separating opposing traffic lanes, median nose radii, curb radii at street intersections, crown height, cross slope, geometric shapes of islands separating traffic movements and other features. Since city streets are differentiated by their functions and location, there is also a variance in the geometry which describes the path vehicular traffic should follow. Design Speed The design speed is a primary factor in the horizontal and vertical alignment on city streets and thoroughfares. Design features such as curvature, radii for turning movements and sight distances are directly related to the design speed. The design speed also affects features such as lane widths, pavement width, pavement cross -fall, pavement crown, and clearances. The design speed is defined as the approximate speed that can be maintained safely by a vehicle over a given section of road when conditions are so favorable that the design features of 40 the roadway govern. The speed limit or posted speed is the maximum legal speed set by local Page 3 of 16 1-25-2000 i The horizontal geometrics of the streets and thoroughfares include the segment of geometric design associated with the alignment, inter -sections, pavement widths, and related geometric elements. The various classifications, utilizing the design speed as a control, must have certain horizontal and vertical geometrics to provide a safe economical facility for use by the public. Horizontal Curves The alignment of the streets and thoroughfares is usually determined by the alignment of the existing right-of-way or structures which cannot be relocated. Changes in the direction of a street or thoroughfare are minimized by constructing a simple curve having a radius that is compatible with the speed of vehicular traffic. Curvature in the alignment of arterials is allowed under certain conditions, but the greater traffic volume and the higher vehicle speeds which accompany these thoroughfares tend to increase the number of accidents when curving of alignment occurs. Curves in the alignment of residential streets usually provide aesthetic value to residential neighborhoods without affecting the orderly flow of traffic or safety. Minimum permitted radii of curvature are shown in Table No. 3. These are based on traffic consisting of typical present day automobiles operating under optimum weather conditions. There are other important considerations in the design of curves Page 4 of 16 1-25-2000 authorities for a certain roadway or area. The design speed should never be less than the likely legal speed limit. The various street and thoroughfare classifications that make up the system within the City require different design speeds according to their use and location. Table No. 2 indicates the allowable design speeds for the various classifications within the City. Lower design speeds (and speed limits) may be permitted for all classifications for unusual conditions, terrain, or alignment.

There are other important considerations in the design of curves Page 4 of 16 1-25-2000 on thoroughfares including the location of intersecting streets, drives, bridges, and other topographic features. Table No. 3 MINIMUM CENTERLINE RADIUS FOR ROADWAYS Street Classification — Minimum Radius (FT) i Arterial-- 40 mph 700 —� LCollector-35 mph_ 500 {I Residential -30 mph 300 Residential streets intersecting a collector street or arterial street will have a tangent section of centerline at least fifty feet (50') in length measured from the right-of-way line of the collector or arterial street. No such tangent is required when the residential street curve has a centerline radius greater than four hundred feet (400') with the center located on the collector street or major street right-of-way line. Reverse circular curves shall be separated by a straight tangent section not less than one hundred feet (100') long. Turning Lanes Turning lanes are provided at intersections to accommodate left -turning vehicles. The primary purpose of these turning lanes is to provide storage for the turning vehicles. The secondary purpose is to provide space to decelerate from the normal speed to a stopped position in advance of the intersection or to a safe speed for the turn in case a stop is necessary. Left turn lanes at intersections shall be twelve feet (12') in width (minimum). Turn lanes shall have a width transition of not less than one hundred fifty feet (150') in length and a storage lane of not less than one hundred fifty feet (150') in length. Street Intersections The intersection at grade of all thoroughfares will be at or near an angle of ninety degrees (900). At the intersection of these thoroughfare types, the various geometrics including pavement widths, lane widths, curb radii, median widths, tuming lane data, crossfall, crown height, and other features differ. Streets often intersect at angles less than ninety degrees (90°); however, no street will be allowed to intersect at less than seventy degrees (700). Table No. 4 shows the curb radii required for intersections at ninety degrees.

Other considerations include adequate clearance between the median nose and through traffic on the intersecting thoroughfare and location of the median nose to properly clear the pedestrian crosswalks. Sidewalks The purpose of the public sidewalk is to provide a safe area for pedestrians. The City of Anna requires that sidewalks be constructed with the paving of streets or when building construction occurs and that all sidewalks conform to state laws for barrier free construction. Concrete sidewalks on residential streets will have a width of not less than four feet (4') and thickness of not less than four inches (4") and will be constructed of three thousand pounds per square inch (3,000 psi) concrete on both sides of all streets. Sidewalks will be constructed not less than one foot (1') from the street right-of-way line and will extend along the street frontage including the side lot corner lots and block ends. Sidewalks on arterial streets and non-residential collectors shall be five feet (5') wide. All concrete for sidewalks will be placed on a two-inch (2") sand cushion and will be reinforced with 6 X 6 No. 6 gauge welded wire fabric or number three (3) reinforcing steel bars spaced at eighteen inches (18") on center each way. The subdivider may petition for a determination by the City that sidewalk construction is either not feasible or inappropriate at the time of subdivision construction. If determined to by inappropriate at the time of construction by the City, funds for such construction shall be placed in escrow with the City by the subdivider. The sidewalk escrow rate will be approved by resolution by the City Council. Vertical Alignment The vertical alignment of all thoroughfares should be designed to insure the safe operation of vehicles by the traveling public and should allow easy access to adjacent property. A travel - way, which is safe for vehicles, is dependent on criteria which considers operating speeds, maximum grades, vertical curves, and sight distance. In addition to these considerations, other factors related to vertical alignment include storm drainage inlet may also be required in the median. In presenting the grades of intersecting thoroughfares in the paving plans, profiles of all four (4) curbs of a thoroughfare will be shown as a continuous grade through the intersection of the other thoroughfare. Minimum Grades Minimum longitudinal grades for streets and thoroughfares are required to insure proper flow of surface drainage toward inlets. Minimum grades are five -tenths percent (.5%) for Portland cement and asphaltic concrete pavement. The minimum grades for cul-de-sacs will be six - tenths percent (0.6%). All valley gutters should be a minimum of eight feet (8') wide and • constructed of reinforced concrete and will have minimum grades of five -tenths percent (0.5%). Page 6 of 16 1-25-2000 0 0 Maximum Grades Maximum longitudinal grades will be compatible with the type of facility and the accompanying characteristics including the design speed, traffic conditions and sight distance. Arterials must move large volumes of traffic at faster speeds, and flatter grades will better accommodate these characteristics. Truck and bus traffic on these type facilities often control traffic movement, particularly if steep grades prevent normal speeds. The normal maximum street grades allowed for Anna streets are shown in Table No. 5. Steeper grades may be permitted for short lengths where required by topographical features or restricted alignment. Table No. 5 MAXIMUM STREET GRADES STREET CLASSIFICATION Arterial Collector Minor Residential Pavement Slope MAXIMUM GRADE 6% 8% 10% On undivided streets, the maximum difference in curb elevations will not exceed five -tenths foot (0.5'). Vertical Curves When two (2) longitudinal street grades intersect at a point of vertical intersection (PVI) and the algebraic difference in the grades is one percent (1.0%) or greater, a vertical curve is required. Vertical curves are utilized in roadway design to affect a gradual change between tangent grades and should result in a design which is safe, comfortable in operation, pleasing in appearance, and adequate for drainage. The vertical curve will be formed by a simple parabola and may be a crest vertical curve or a sag vertical curve. Stopping Sight Distance Crest Vertical Curve When a vertical curve is required, it must not interfere with the ability of drivers to see a length of street ahead, should they be required to suddenly stop. This length of street, called the stopping sight distance, should be sufficient length to enable a person in a vehicle having a Page 7 of 16 1-25-2000 eye height of three and three quarters feet (3.75') above the pavement and traveling at or near • design speed to stop before reaching an object in his path five tenths foot (0.5') in height. The minimum stopping sight distance is the sum of two distances: 1) The distance traversed by a vehicle from the instant the driver sights an object for which a stop is necessary to the instant the brakes are applied; and 2) The distance required to stop the vehicle after the brake application begins. • The minimum safe stopping sight distances for the City of Anna street types are shown in Table No. 6. These sight distances are based on each design speed shown and on wet pavement. The minimum length of crest vertical curve required for the safe stopping sight distance of each street type may be calculated using the formula L = KA. The values of K for a crest vertical curve are also shown in Table No. 6. Table No. 6 MINIMUM LENGTH OF A VERTICAL CURVE CREST VERTICAL CURVE L = KA where L = minimum length vertical curve required for safe stopping sight distance; K = horizontal distance in feet required to effect a one percent change in gradient; and, A = algebraic difference in grade. SAG VERTICAL CURVE L = KA where L = minimum length vertical curve required for safe stopping sight distance; K = horizontal distance in feet required to effect a one percent change in gradient; and, A = algebraic difference in grade.

The minimum length of sag vertical curve required shall be calculated using the formula L = KA and the values of K for a sag vertical curve are shown in Table No. 6. Intersection Grades The grade of an intersecting street with the principal street gutter should not be generally more than four percent (4%) either up or down within the first twenty feet (20') beyond the curb line of the principal street except that in very hilly terrain a maximum intersecting grade of six percent (6%) can be considered. Grade changes of one percent (1%) or more require vertical curves. Median Openings The following standards for median openings are established to facilitate traffic movement and promote traffic safety. Median openings will normally be permitted at all intersections with dedicated City of Anna Streets. Exceptions would be at certain minor streets where, due to unusual conditions, a hazardous situation would result. Normal spacing between median openings should be no more than twelve hundred feet (1,200'). Mid -block median openings or other openings with left turns permitted into adjacent property will not normally be permitted unless all the following conditions exist: • The property to be served is a significant traffic generator with demonstrated or projected trip generation of not less than two hundred fifty (250) vehicles in a twelve (12) -hour period. • The median opening is not less than four hundred feet (400') from an intersection with an arterial thoroughfare. • The median opening is not less than two hundred sixty feet (260') from an intersection with II t a co ec or thoroughfare. • The median opening is not less than three proposed median opening. Th hundred feet (300') from any other existing or • e median width is sufficient to permit the construction of a left turn storage lane. • Median openings will not be permitted in left tum storage lanes, Wherever possible, median openings should serve both sides of a thoroughfare. Driveway and Curb Openings The minimum distance between driveways is normally twenty feet (20'). The distance between one-way, ninety -degree (900) drives can vary between four feet (4') and twenty feet (20'). The island between angle drives should equal or exceed fifty square feet (50 S.F.) in area. In all cases, driveway locations must conform to minimum safe sight distance and stopping sight distance standards. Page 9 of 16 1-25-2000 • Driveway Grades The normal driveway grade within the street right-of-way is one-quarter inch per foot rise above the top of curb at the property line. The minimum elevation of a driveway at the right-of-way is two inches (2") above the top of the curb. Barrier free sidewalk construction requires a maximum driveway grade as measured from the gutter of eight percent (8%). Where driveway construction or reconstruction must occur off the street right-of-way, the usual maximum grade is fourteen percent (14%). The maximum change in grade without vertical curve is twelve percent (12%) for any ten feet (10) in distance. Driveways should be profiled for a distance of at least twenty-five feet (25) outside the right-of-way to ensure adequate replacement design. Due to state laws requiring barrier free construction of sidewalks, steps or other abrupt changes in sidewalk grades are prohibited at driveways. Alley Grades Alleys are constructed with a 5 -inch inverted crown for drainage. The maximum grades for alleys are eight percent (8%) within thirty feet (30') of an intersection with a street and fourteen percent (14%) elsewhere, unless otherwise approved by the City, and the minimum grade is four tenths percent (0.4%). Changes in grade, including intersections with streets, may not exceed three percent (3%) without providing vertical curves. Pavement Design Factors which influence the performance of thoroughfare pavement include the subgrade upon which the pavement structure rests, the quality of materials used to construct the pavement, and the type and amount of traffic using the facility. In designing a pavement that will provide a reasonable degree of performance during an expected life, certain factors can be predetermined. The load bearing capacity of the subgrade will be determined by making a soils engineering investigation of the site. The strength of the pavement can also be established by specifications and quality control during construction. Standard pavement sections are established in Table No. 10A, "Minimum Standard Concrete Street Pavement Design" and Table 10B "Minimum Standard Asphalt Street Pavement Design". Unusual design conditions may be encountered that will preclude the use of Table No. 10A or 10B. The proposed pavement will be designed in accordance with the geotechnical investigation or Table No. 10A or 108, whichever is more restrictive.
