recharge and surface water runoff over and off the site.
Describe how downstream properties will be affected by any changes to the above parameters.

Land Alteration Information
Identify all Critical Areas located on or adjacent the project site.
Wetlands Hillsides Geologically hazardous areas
Erosion and landslide hazard areas
StreamsFlood hazard areas
Ravine Sidewall or Bluff Seismic hazard areas
Fish and wildlife habitat conservation areas
Critical aquifer recharge areas
Identify the area for each existing slope category as a percentage of the total site area located on the proposed project site
0 - 15% Slope: 15 - 25% Slope:
40+% Slope:25 - 40% Slope:
Amount of Disturbance Allowed. The following chart sets forth the maximum slope disturbance allowed on a
development site:
The overall amount of disturbance allowed on development sites which have any combination of the above slope categories
shall be determined by the following formula:
(Square Footage of Site having 0 – 15% slopes) X 1.00 + (Square Footage of Site having 15 – 25% slopes) X 0.60 +
(Square Footage of Site having 25 – 40% slopes) X 0.45 + (Square Footage of Site having 40%+ slopes) X 0.30 =
Total Amount of Allowable Site Disturbance.
If the proposal will exceed the maximum disturbance limits the applicant must submit a Environmentally Critical Area
Development Exception Application in order for the City to determine if the City will authorize a deviation from this
0 - 15% 100% 1.00
15 - 25% 60% 0.60
25 - 40% 45% .45
40%+ 30% .30
Will rockeries or retaining walls be required? If yes, identify location and height on plan.
Yes No
Will rockeries or retaining walls be over four feet as measured from the bottom of the footing or retaining a surcharge?
Yes No
If the answer is yes to the above question, please contact the Building Division of the Planning, Building and Public Works
Department as a Building Permit maybe required for the construction of the identified rockery or retaining wall. If a
Building Permit is required, the Grading Permit will not be issued until approval of the required Building Permit.

fill is to be placed on the site. Also, list the composition of the fill material.
Will grading activity occur within twenty (20) feet of an adjacent property?
