While the Plan for Portsmouth does not necessarily fit neatly into these eight categories, for purposes of consistency with other communities’ plans, these elements are used and the order in which the elements are presented are as recommended by the State. The Goals and Policies Statement, rather than being a separate element, is contained at the beginning of each element and sub-element under “Goals” and “Objectives.” Due to their individual importance, and because breaking them up among the other elements would be ineffective, Agriculture, Prudence Island, and Hog Island each have additional elements of their own. Within some elements there are sub-elements, each of which is organized and approached as if a separate element: ELEMENT #1 LAND USE ELEMENT #2 HOUSING ELEMENT #3 ECONOMIC DEVELOPMENT ELEMENT #4 NATURAL and CULTURAL RESOURCES: ELEMENT #4A WATER QUALITY ELEMENT #4C RESOURCE PROTECTION ELEMENT #4D SEPTIC ELEMENT #4E SOIL and AIR QUALITY ELEMENT #4F WATERFRONT and COASTAL ELEMENT #4G HISTORICAL ELEMENT #5 FACILITIES and SERVICES ELEMENT #5A FACILITIES and SERVICES ELEMENT #5B WATER SUPPLY ELEMENT #6 OPEN SPACE and RECREATION: ELEMENT #6A OPEN SPACE ELEMENT #6B RECREATION ELEMENT #7 CIRCULATION ELEMENT #8 AGRICULTURE ELEMENT #9 PRUDENCE ISLAND ELEMENT #10 HOG ISLAND ELEMENT #11 IMPLEMENTATION MAPS 1 COMPREHENSIVE PLAN - INTRODUCTION 2 To maintain a logical flow from the broad to the specific, each element and sub-element is set up in the same outline fashion, going from overall goal statement through to implementation items. Every recommendation has a reason. While it is not always necessary to read each element from beginning to end, a full understanding of why any particular item is included can be found in the goals, needs and objectives. GOAL DEFINITIONS NEED OBJECTIVE OBJECTIVE OBJECTIVE OBJECTIVE Implementation Implementation Implementation Implementation Implementation Implementation Implementation There is not a one-to-one relationship between objectives and implementation steps. Implementation items do not necessarily flow directly from a single objective, and they often apply to more than one objective. Some, particularly in the Land Use Element, even apply to more than one element. For the sake of brevity, we have tried to avoid having the same implementation item in more than one place. That is not always possible in that the reader could be left hanging after reading objectives and finding no implementing tool. LOCATION OF DATA AND MAPS Data is located within the text of each element. Where such information is needed elsewhere in the text, it is referred to rather than repeated. There are over 50 maps in this Comprehensive Plan. Due to their multiple uses, all maps are in a separate section at the end of the Plan.
