Drawing Contour Lines Drawing Profiles Site Planning with CADD

3 Site Design Considerations
Minimum driveway and lawn slope of 1/4” per foot Single-car driveway at least 10’ Double-car driveway at least 18’ Minimum turn radius of 15’ for a driveway

4 Site Design Considerations

5 Site Design Considerations
Leave room for expanded utilities Do not encroach on easements (property right-of-way) Follow basic grading rules Identify remaining trees after construction Design retaining walls to minimize erosion and maintain a level lawn

6 Property Lines Label boundaries with a bearing and distance
The Delta angle () is the included angle of the curve if the boundary is not straight

7 Steps in Site Layout Select the proper paper size and scale
Lay out the site plan based on a given plat or legal description using construction lines Draw only the outline of the floor plan Include setbacks, sidewalks, and other features

8 Steps in Site Layout

9 Steps in Site Layout Darken all property and other lines
Add dimensions and elevations Keep extension and dimension lines short Label important features Add north arrow, legal description, title, scale, client’s name, and other pertinent information

10 Steps in Site Layout

11 Drawing Contour Lines Grid Survey - Divides the plot into small squares like a checkerboard Control Point Survey - Uses elevations recorded on a map to create the plot Radial Survey - A series of angular and distance measurements are established from a given central point

12 Using Grid Survey Drive stakes into the ground in a grid pattern at a particular elevation Space stakes at a common interval Label vertical lines with letters Label horizontal lines with numbers (stations) Transpose field notes onto grid

13 Drawing Contour Lines Draw a grid or create a GRID layer
Label elevation at grid intersection using field notes Determine contour interval and connect points Estimate remaining lines Label elevation on index contour lines and darken them

14 Drawing Contour Lines

15 Drawing Profiles Profile is a vertical section of the ground surface and earth below Draw the profile line on the contour map Establish vertical scale Project a line vertically to elevation line from each contour crossing of the profile line Draw the profile by connecting the points

16 Drawing Profiles

17 Drawing Grading Plan This plan shows the elevations after excavation
It shows areas where earth is removed (cut) and added (fill)

18 Drawing Grading Plan Determine the angle of repose and areas to cut and fill Draw parallel lines to represent elevation at the cut and fill Mark points where parallel lines and contour lines intersect Connect all points and shade cut and fill areas

20 Site Planning with CADD
Site plans are more accurate Symbols are loaded into the program for easy retrieval Terrain model shows contour lines in 3D
