6 2 2 Easements: 1 10 Utility Easement 1 16 Utility Easement 2 Adjacent Land Uses: 1 Commercial 1 Residential 2 Bordering Streets: 1 Side Street 1 Frontage Street Developing Tree Canopy Analysis Report

7 2 3 Tree Preservation Zones: 1-25 Frontage T.P.Z. (behind 16 U.E.) 1 18 Side Street T.P.Z Residential T.P.Z. (15 behind 10 U.E.) ***INVENTORY PROTECTED TREES IN ALL TREE PROTECTION ZONES*** Developing Tree Canopy Analysis Report

8 2 Calculations: 1) Add together Square Footage of Protected Trees in the 3 Tree Preservation Zones 2) Calculate Square Footage of Woodland Tree Stands 3) Calculate Understory Square Footage if to remain after development (understory preservation = ½ Woodland Tree Stand area) NOTES: 1) Show Tree Protection Fencing around Protected Trees and Woodland Tree Stands 2) A 6 landscape screen or opaque barrier needed along property line abutting residential area. Developing Tree Canopy Analysis Report

9 2 HEALTHY TREE A tree free from significant stress, damage, disease, insect infestation, or other conditions that substantially reduce the prospect of long term viability. Tree shall have a fair to well developed crown and less than 20% deadwood. Healthy Ash Developing Tree Canopy Analysis Report

10 2 MEASURING DIAMETER AT BREAST HEIGHT OR DBH The diameter of a tree trunk to the nearest inch measure 4.5 above ground level at the tree base Measurement made on uphill side of tree on sloping terrain Developing Tree Canopy Analysis Report

11 2 PROTECTED TREE A tree that is 6 or greater in DBH, located in a designated tree preservation zone per the ordinance. Protected Tree Square Footage Flagging and Tagging Protected Trees Developing Tree Canopy Analysis Report

12 2 HERITAGE TREE A tree species listed on the Texas Forest Service list of native and naturalized trees of Texas that has a circumference not less than 75% of the threshold circumference required for classification as a big tree. Website: Click on: Texas Big Tree Registry Eligible Species Developing Tree Canopy Analysis Report

13 2 HERITAGE TREE CONTINUED Developing Tree Canopy Analysis Report

14 2 WOODLAND TREE STAND An area of contiguous wooded vegetation covering at least 2,500sf where trees are at a density of at least 1 protected tree per 500sf of land and where the branches and leaves form a canopy over substantially all the area. Developing Tree Canopy Analysis Report

15 2 UNDERSTORY The underlying layer of vegetation growing below the forest canopy including smaller trees, saplings, and shrubs, but not including grasses or other ground covering vegetation. Protected Trees with Understory along Road Frontage Developing Tree Canopy Analysis Report

16 2 HAZARD TREE A tree that dangers the public health, safety or welfare or that poses a threat of injury to persons or property, including other trees, by virtue of damage, disease, insect infestation, instability or other injurious conditions. Target Present No Target Present Developing Tree Canopy Analysis Report

31 3 PARKING LOT TREES 60sf of tree canopy must be preserved or planted for each additional parking space. Trees must be located in the interior of the parking lot or immediately adjacent to it. For parking lots of 250 spaces or more, at least 50% of parking trees must be located within the interior of the parking lot Tree Preservation, Landscape, & Irrigation

32 3 PARKING LOT TREES Table II. Preferred Species List Only trees of the preferred species listed in section may be used to satisfy the planting requirements of this section. All trees must be at least 3 caliper and no less than 25% of the planted parking lot trees must be at least 4 caliper trees. Tree Preservation, Landscape, & Irrigation

33 3 MEASURING TREE CALIPER Caliper Measured 6 above the root ball for trees 4 in diameter Or Measured 12 above the root ball for larger nursery stock Tree Preservation, Landscape, & Irrigation

34 3 PARKING LOT SCREENING Screening shall consist of shrubs planted along each perimeter line of a parking lot facing a public street, exclusive of driveway entrances and pedestrian walkways. Required # of Shrubs = Perimeter in Feet/3 Shrubs shall be maintained at a height of not more than 36 or less than 24. Shrubs shall be planted at equal spacing (3 O.C.). Tree Preservation, Landscape, & Irrigation

35 3 NEW TREE PLANTING REQUIREMENTS 1 2 Not less than 50% of the new trees planted shall be evergreen Not more than 75% may be of the large tree category Tree Preservation, Landscape, & Irrigation
