A picture tells a thousand words... this could not be more true when preparing for your appeal.  Take as many pictures as you can -- before, during, and after the tree permitting, cutting, construction process, etc.  You may not even need some of the pictures for your appeal, but keep them anyway as sometimes other trees not included in the permit are cut down or harmed during construction and you will need these pictures as proof.

With your appeal, submit photographs of the site and of any specific trees or areas on the site that do not meet the Tree Protection Ordinance requirements.   This is especially important if you are trying to illustrate disregard for tree protection fencing, siltation, or storing of construction materials in the root protection area.  Label each photo you plan to show to the Tree Commission with the section of the ordinance to which the picture pertains. Make a clear case for each ordinance violation with photos, citations of the ordinance, and a comparison to the approved site plan versus the conditions on the site.  The Tree Commission must be able to determine clearly and quickly what the violations are on the site based on your presentation.

Helpful Hints:

Show the scale:  Photographs are more meaningful when it's clear what the scale is.  If you can (although this is not always possible given that you may be restricted from going onto the property), use a vertical and horizontal scale in each photo that shows any distances/measurements that are part of your appeal.  Scales can be created by using a wooden 1x2 painted with numbers for each foot of distance. Use the scales to make these measurements easily visible in the photos so the Tree Commission can see the actual conditions on the site.  If you are unable to use a scale, try to take your pictures so that the size of the objects in your photo are easy to understand, i.e. have a person standing in your photograph to represent an object around 5 1/2 or 6 feet as a basis of comparison.  Document how far away the person is standing from the tree or other object you are showing in your picture.

Timestamp your photos:  If your camera allows a date and time to be stamped on the pictures, make sure to use this feature.  If not, make sure to record the date each photo was taken.
