2.0 METHODOLOGY 2.1 INVENTORY All streets within the City are categorized as either arterial or local streets and are grouped as such into their respective networks; collectively they comprise the entire pavement network. Within each network, the streets are ranked based on their functional classifications (refer to Section 3.0 Pavement Network) and are assigned a letter that corresponds with the rank. In the case of the arterial network, the letter `B' is assigned to major arterial streets, the letter `P' is assigned to primary arterial streets, the letter `S' is assigned to secondary arterial streets, and the letter 'C' is assigned to collector arterial streets. In the case of the local network, the letters 'E' and 'I' are assigned to residential and non-residential streets, respectively. Each street, or branch, is divided into segments, or sections, at intersecting streets and railroads. For example, Main Street from First Street to Second Street and Grand Avenue from Railroad to Chestnut Avenue. Additionally, a section break is introduced where a change in pavement surface is encountered mid -block. For example, if the pavement surface were to change from Asphalt Concrete (AC) to Portland Cement Concrete (PCC) at any point along Main Street from First Street to Second Street, then the resulting sections would be Main Street from First Street to AC- PCC Transition and Main Street from AC-PCC Transition to Second Street; where one section has an AC surface and the other has a PCC surface. In an effort to help identify and sort the streets efficiently, identifying numbers are assigned to each branch and section. A Branch ID is a six -digit number assigned to each branch and is numbered increasingly with numbered streets listed first followed by the remainder of the streets listed in alphabetical order. A Section ID is a four -digit number assigned to each section and is numbered increasingly based on geography from west to east and from south to north. For example, the westernmost or southernmost section of a branch would have a Section ID with the lowest number and the easternmost or northernmost section of a branch would have a Section ID with the highest number. Furthermore, the four -digit Section ID number may be followed by a letter such as N, S, E, or W that denotes the direction of travel (north, south, east, and west, respectively) along a street. This letter is used to differentiate between the two halves of a street when it is divided as such. For example, Section ID 110ON and Section ID 1100S would denote the northbound and southbound sides of a section, respectively. Additionally, other sort features are available to assist in further grouping segments with similar characteristics. For example, to identify streets within pre -defined geographical areas, each section is labeled with a number that corresponds to either a neighborhood or a non -neighborhood area. A neighborhood area, which is typically comprised of churches, schools, and residential properties, is defined as the boundary established through a collaboration of the City's Community Development Agency (CDA) and local residents based on both geographic and social components. Currently, there are 64 neighborhoods established in the City, which meet with CDA staff regularly to develop strategies to shape it for the better and sustain it for the long term. A non -neighborhood area refers to the zone located outside of the established neighborhood boundaries comprising of mostly commercial and industrial uses.
