TREE PRESERVATION POLICY <br />reserves. <br />11. Soil compaction - A change in soil physical properties <br />which includes an increase in soil weight per unit volume , and a <br />decrease in soil pore space. Soil compaction is caused by repeated <br />vibrations, frequent traffic and weight. As related to tree roots, <br />compacted soil can cause physical root damage, a decrease in soil <br />oxygen levels with an increase in toxic gasses, and can be <br />impervious to new root development. <br />12. Transport roots - The system for framework of tree roots <br />comprised of major woody roots and rope roots. <br />APPENDIX B <br />1. A tree's ability for adequate root development, and <br />ultimately its chances for survival, are improved with reclamation <br />of the growing site. <br />a. Wherever possible, the soil should be brought back <br />to,its natural grade. Unnecessary fill, erosion sedimentation, <br />concrete washout, and construction debris should be removed. When <br />machinery is required for site improvement, it is recommended that <br />a "bob -cat" or similar lightweight rubber tire vehicle be used so <br />as to minimize soil compaction. <br />APPENDIX C CHECKLIST FOR TREE PROTECTION PLAN REVIEW <br />CONTACT THE CITY OF LINO LAKES FORESTRY DEPARTMENT AT 464 -5562 FOR <br />A SITE INSPECTION UPON COMPLETION OF LANDSCAPE INSTALLATION. <br />1. Tree Protection Plans <br />a. Provisions for tree protection on the site shall be, <br />as minimum, in conformance with the requirements of the City of <br />Lino Lakes Tree Preservation Section of the Tree Ordinance. <br />b. A tree protection plan shall be submitted either as <br />part of the landscape plan, or as a separate drawing to include the <br />following: <br />1.( All tree protection zones <br />2.) Approximate location of all specimen trees or <br />stands of trees <br />3.) Approximate location of all specimen trees when <br />their preservation is questionable, or might result in a change of <br />the site design <br />4.) Indicate those specimen trees to be removed. <br />Removal of specimen trees is subject to City Forester approval <br />5.) Limits of clearing and land disturbance such as <br />grading, trenching, etc. where these disturbances may affect tree <br />protection zones <br />6.) Proposed location of underground utilities <br />7.) Methods of tree protection shall be indicated <br />for all tree protection zones, aeration systems, staking, signage, <br />etc. <br />Page 8 <br />
