(2) Maps show physical features of the natural or built environment at established scale and orientation. Plans are engineered drawings made to scale showing existing physical features of a site and proposed changes to accommodate development..

(12) Scale. 20’ !. 35’.

(13) Key Elements of Plans Written Scale 1:12,000 (ratio) 1” = 1,000’ (equivalent). Graphic scales are the most reliable!. Beware of Xerox Distortion. Graphical Scale.

(14) Measuring Distances Engineering Scales. 40 ft. 240 ft. Map Scale. Meaning. 10. 1 inch = 10 ft. 20. 1 inch = 20 ft. 30. 1 inch = 30 ft. 40. 1 inch = 40 ft. 50. 1 inch = 50 ft. 60. 1 inch = 60 ft. 400 ft.

(18) Your planner, if you have one, will have reviewed the plans and may issue a pre-meeting memo highlighting any issues. Use your planner as a resource to help you focus in on issues or problems. This is a team effort will all staff being part of the team..

(20) Contours: an imaginary line that connects points of equal elevation.

(21) Topography Cross-sections are sometimes used to represent 3-D objects in 2 dimensions..

(22) Topography Cross-sections are sometimes used to represent 3-D objects in 2 dimensions.. Vertical scale sometimes exaggerated to better show change.

(23) Contours always connect, but not always within the map boundaries... topography of 2 hills. This could be the edge of a presented map.

(24)

(25)

(26) Slope direction is calculated perpendicular to the contour lines.. Water flows downhill.... ...so the direction of flow is always perpendicular to the. contour lines, since this is the steepest slope.

(27) Many maps are in the form of topographical maps aka ‘topo’ Interpreting a 3D world in 2D.

(28) a spot elevation is a point of known elevation used as a pt of reference for surveys.. a contour interval is the vertical distance b/w contours. 10’ on topos; 2-5’ on site plans every 5th contour is an index contour shown in bold. a benchmark (BM): point of known position & elevation used as a pt of reference for surveys.. contours far apart show a gentle slope. contours close together show a steep slope. a series of concentric contours ending in a small closed circle or oval shows a local hilltop. contours very close together show a cliff contour lines of a ridge are in a “U” that always points downhill. green areas show forest cover; white areas denote fields contours at a stream form a “V” that always points uphill.

(35) If too Steep: - potential erosion - soil stability - safety. 10 ft. 20 ft.

(36) If too flat: - storm water may not drain - may flood. 0 ft. 20 ft.

(37) Plan to divide one lot into 3 or more Town regulates lot size, frontage, setbacks, road construction, etc Planning Commission’s Role. Once approved, each home builder submits construction documents for building permit; once complete a CO is issued (Certificate of Occupancy).

(38) Zoning Commission for administrative review to see if it meets regulations. If it doesn’t meet regulations, must go to Zoning Board of Appeals for variance ZBA can only grant variances if there is a hardship with the ‘land’.
