(12)
Landscaping credits:
a.
Purpose. Credits for trees and shrubs are intended to encourage the enhancement of the lot through additional landscaping elements and to provide relief to parcels that are configured in such a way as to make the fifteen (15) percent landscape area requirement less burdensome.
b.
General criteria. As an alternative to the required fifteen (15) percent total landscaped area, landscape credits may be utilized to reduce the total amount of land area dedicated for landscaping purposes. However, in no instance shall the credits reduce the total amount of landscaping on a lot to less than ten (10) percent of the total land area. Credits are allowed for existing or newly planted trees and shrubs, and only if the feature is maintained as a permanent element of the landscape plan. No credit will be given for "undesirable species", a list of suggested undesirable trees is shown in Table 21-3.
All landscaped areas, including trees, shrubs, vines, grasses and groundcover that received landscaping credits, shall be properly maintained. If any plant material dies, such material shall be subject to replacement as specified in Table 21-2.
c.
Credit for trees. Credit shall be allowed according to Table 1. Any plant type or species maybe used in the landscaping plan. However, landscaping credit shall be allowed only for those trees contained in Table 21-2.

Tree replacement requirements.
a.
Replacement tree specifications: In the event that it is necessary to remove a tree which is three (3) inches or greater via permit approval, the applicant, as a condition to issuance of a tree removal permit, shall be required to replace the trees being removed with quality trees as defined herein. A sufficient number and diameter of replacement trees shall be planted in order to equal the total diameter inches of fraction thereof trees three (3) inches or greater and slated for removal or removed in violation of this section. Replacement trees shall be a minimum of three (3) inches diameter when measured one (1) foot above the soil line a minimum of eight (8) feet in height when planted.
Examples:
1.
A total of eighteen (18) diameter inches removed shall be replaced with six (6) three-inch diameter trees.
2.
A total of nineteen (19) diameter inches removed shall be replaced with seven (7) three-inch trees or five (5) three-inch trees and one (1) four-inch tree.
b.
Procedures: Replacement trees shall be located on the subject site whenever possible. However, if this is not feasible, an applicant may initiate a proposal to plant trees off-site. This may be approved if the planting site is in reasonable proximity to the project area. The city has the authority to allow the planting to take place on another property or to allow the applicant to make a payment of the prevailing rate for installed trees per diameter inch in lieu of replanting the trees to be removed (sixty dollars ($60.00) per diameter inch initially) into a tree and landscape redevelopment fund.
c.
Restrictions: Easements and rights-of-way: The location of replacement trees is restricted from utility easements and rights-of-way. The location shall not be in an area such that the mature canopy of the tree will interfere with overhead utility lines. No trees shall be planted within ten (10) feet of a fire hydrant.
d.
Guarantees: All replacement trees shall be guaranteed for two (2) years from the date of the final inspection and acceptance of the project. The entire site shall have a survival rate of eighty-five (85) percent or greater.
e.
Timing: Replacement trees shall be planted prior to the issuance of the certificate of occupancy or project release. Optimum planting times do not always correspond to project completion. For that reason, replacement tree plantings may take place after the project is released by the city; provided, that before project release, a fiscal security is posted in the amount equal to the prevailing rate for installed trees with a one-year guarantee, plus fifteen (15) percent to cover administrative cost.
(7)
Tree protection. A major purpose of this section is to protect all trees which are not removed and to allow approved construction to occur. The following procedures shall apply to all types of construction projects which involve development around trees.
The following procedures are deemed appropriate in the situations noted; however, unique circumstances may allow modifications if deemed necessary by the administrative official.
a.
Prohibited activities: The following activities shall be prohibited with the limits of the drip line of any tree which is subject to the requirements of this section.
1.
Material storage: No materials intended for use in construction or waste materials accumulated due to excavation or demolition shall be placed within the limits of the drip line of any tree.
2.
Equipment cleaning/liquid disposal: No equipment may be cleaned or other liquids deposited within the limits of the dripline of a tree. This would include but not be limited to, paint, oil, solvents, asphalt, concrete, mortar or other materials.
3.
Tree attachments: No signs, wires or other attachments, other than those of a protective nature shall be attached to any tree.
4.
Vehicular traffic: No vehicular and construction equipment traffic or parking is allowed within the limits of the dripline of trees.
b.
Pre-construction: The ensuing procedures shall be followed prior to construction.
1.
Tree flagging: All trees to be removed from the construction site shall be flagged with bright red vinyl tape wrapped around the main trunk at a height of four feet (4) or more such that the tape is visible to workers on foot or driving equipment.
2.
Protective fencing: All trees shall have protective fencing located at the tree's drip line. The protective fencing may be comprised of snow fencing, orange vinyl construction fencing, chain link fence or other similar fencing with a four-foot (4) approximate height. The protective fencing may be located within the drip line of the specimen tree for approved construction only. The fencing shall follow the delineation of the approved construction.
3.
Bark protection: In situations where a tree remains in the immediate areas of intended construction, the tree shall be protected by enclosing the entire circumference of the tree's trunk with lumber encircled with wire or other means that does not damage the tree.
4.
Construction pruning: In a case where a low hanging limb may be broken during the course of construction, the obtrusive limb may be cut. The limb shall be cut either flush to the trunk on or at the next joint of the limb. The wound shall then be sealed with pruning paint. In no instance shall pruning involve a portion of the trunk or thirty (30) percent of the entire canopy without the administrative official's prior approval.
c.
Improvement within the critical root zone of a tree: Design constraints often dictate that trees slated for preservation have some encroachment on their critical root zone. The following is the minimum design criteria which is allowed within the critical root zone of a tree. Development exceeding the criteria would put the tree at risk and therefore no longer be considered a preserved tree. In such a case replacement trees shall also be required.
1.
Grade changes: In the event that grade changes must be made around a tree or group of trees, the following should be implemented in order to maintain oxygen and water exchange within the tree's critical root zone.
i.
Minimum of seventy-five (75) percent of the critical root zone must be preserved at natural grade with natural ground cover or landscaping for the tree to be considered a preserved tree.
ii.
No cut or fill greater than two (2) inches shall be located closer to the tree trunk than one-half (½) of the radius of the critical root zone radius distance.
iii.
Increase grade: Provide an aeration system just outside the tree's drip line. A dry well located a minimum of one-half (½) of the radius of the critical root zone.
iv.
Decrease grade: Provide retaining walls outside the dripline to mitigate cuts.
2.
Boring of utilities: May be permitted under protected trees in certain circumstances. The minimum length of the bore shall be the width of the tree's canopy and shall be a minimum depth of forty-eight (48) inches.
3.
Trenching: Irrigation systems shall be designed to avoid trenching across the critical root zone of any tree.
4.
Paving: A maximum of twenty-five (25) percent of the critical root zone of a tree may be covered with impervious paving. The pavement and the cut and fill for the pavement is to not exceed one-half (½) of the critical root zone radius distance.
d.
Notes required as a part of all construction plans:
1.
All trees shown on this plan to be preserved shall be protected during construction with temporary fencing. Tree protection fences shall be installed prior to the commencement of any site preparation work (clearing, grubbing or grading).
2.
Fences shall completely surround the tree or clusters of trees. The fence shall be located at the outermost limits of the tree branches or dripline. The fence will be maintained throughout the construction project in order to prevent the following:
i.
Soil compaction in the critical root zone resulting from vehicular traffic or storage of equipment or materials.
ii.
Critical root zone disturbances due to grade changes greater than two (2) inches cut or fill, or boring which was not authorized by the city.
iii.
Wounds, to the trunk, limbs or exposed roots by mechanical equipment.
iv.
Other activities detrimental to trees such as chemical storage, cement trunk cleaning, and fires.
3.
In cases of area constraints where the protective fence is closer to the trunk than four (4) feet, the trunk must be protected with strapped-on planking to a height of eight (8) feet or to the limits of the lower branching.
4.
All grading within critical root zones of specimen trees shall be performed by hand or small equipment to minimize damage. Prior to grading, relocate the protective fencing to two (2) feet behind the grade change area.
5.
Trees most heavily impacted by construction activities should be watered deeply once a week during periods of hot and dry weather. Tree crowns should be sprayed with water periodically to reduce dust accumulation on the leaves.
6.
Trenching for landscape irrigation shall be located as far from the existing trunks as possible.
7.
Pruning to provide clearance for structures, vehicular traffic and equipment shall take place before construction begins.
(8)
Violations. Any person violating or failing to comply with any provision or requirement of this section shall be deemed guilty of a misdemeanor and, upon conviction thereof, shall without exception, be fined the maximum amount provided in this chapter.
a.
A monetary penalty of one hundred dollars ($100.00) per diameter inch of the tree(s) removed or damaged shall be assessed and paid to the City of Hurst.
b.
A separate offense shall be deemed committed upon each day during or on which each separate violation or failure to comply occurs or continues to occur and shall be punishable as such.

(12)
Landscaping credits:
a.
Purpose. Credits for trees and shrubs are intended to encourage the enhancement of the lot through additional landscaping elements and to provide relief to parcels that are configured in such a way as to make the fifteen (15) percent landscape area requirement less burdensome.
b.
General criteria. As an alternative to the required fifteen (15) percent total landscaped area, landscape credits may be utilized to reduce the total amount of land area dedicated for landscaping purposes. However, in no instance shall the credits reduce the total amount of landscaping on a lot to less than ten (10) percent of the total land area. Credits are allowed for existing or newly planted trees and shrubs, and only if the feature is maintained as a permanent element of the landscape plan. No credit will be given for "undesirable species", a list of suggested undesirable trees is shown in Table 21-3.
All landscaped areas, including trees, shrubs, vines, grasses and groundcover that received landscaping credits, shall be properly maintained. If any plant material dies, such material shall be subject to replacement as specified in Table 21-2.

Tree replacement requirements.
a.
Replacement tree specifications: In the event that it is necessary to remove a tree which is three (3) inches or greater via permit approval, the applicant, as a condition to issuance of a tree removal permit, shall be required to replace the trees being removed with quality trees as defined herein. A sufficient number and diameter of replacement trees shall be planted in order to equal the total diameter inches of fraction thereof trees three (3) inches or greater and slated for removal or removed in violation of this section. Replacement trees shall be a minimum of three (3) inches diameter when measured one (1) foot above the soil line a minimum of eight (8) feet in height when planted.
Examples:
1.
A total of eighteen (18) diameter inches removed shall be replaced with six (6) three-inch diameter trees.
2.
A total of nineteen (19) diameter inches removed shall be replaced with seven (7) three-inch trees or five (5) three-inch trees and one (1) four-inch tree.
b.
Procedures: Replacement trees shall be located on the subject site whenever possible. However, if this is not feasible, an applicant may initiate a proposal to plant trees off-site. This may be approved if the planting site is in reasonable proximity to the project area. The city has the authority to allow the planting to take place on another property or to allow the applicant to make a payment of the prevailing rate for installed trees per diameter inch in lieu of replanting the trees to be removed (sixty dollars ($60.00) per diameter inch initially) into a tree and landscape redevelopment fund.
c.
Restrictions: Easements and rights-of-way: The location of replacement trees is restricted from utility easements and rights-of-way. The location shall not be in an area such that the mature canopy of the tree will interfere with overhead utility lines. No trees shall be planted within ten (10) feet of a fire hydrant.
d.
Guarantees: All replacement trees shall be guaranteed for two (2) years from the date of the final inspection and acceptance of the project. The entire site shall have a survival rate of eighty-five (85) percent or greater.
e.
Timing: Replacement trees shall be planted prior to the issuance of the certificate of occupancy or project release. Optimum planting times do not always correspond to project completion. For that reason, replacement tree plantings may take place after the project is released by the city; provided, that before project release, a fiscal security is posted in the amount equal to the prevailing rate for installed trees with a one-year guarantee, plus fifteen (15) percent to cover administrative cost.
(7)
Tree protection. A major purpose of this section is to protect all trees which are not removed and to allow approved construction to occur. The following procedures shall apply to all types of construction projects which involve development around trees.
The following procedures are deemed appropriate in the situations noted; however, unique circumstances may allow modifications if deemed necessary by the administrative official.
a.
Prohibited activities: The following activities shall be prohibited with the limits of the drip line of any tree which is subject to the requirements of this section.
1.
Material storage: No materials intended for use in construction or waste materials accumulated due to excavation or demolition shall be placed within the limits of the drip line of any tree.
2.
Equipment cleaning/liquid disposal: No equipment may be cleaned or other liquids deposited within the limits of the dripline of a tree. This would include but not be limited to, paint, oil, solvents, asphalt, concrete, mortar or other materials.
3.
Tree attachments: No signs, wires or other attachments, other than those of a protective nature shall be attached to any tree.
4.
Vehicular traffic: No vehicular and construction equipment traffic or parking is allowed within the limits of the dripline of trees.
b.
Pre-construction: The ensuing procedures shall be followed prior to construction.
1.
Tree flagging: All trees to be removed from the construction site shall be flagged with bright red vinyl tape wrapped around the main trunk at a height of four feet (4) or more such that the tape is visible to workers on foot or driving equipment.
2.
Protective fencing: All trees shall have protective fencing located at the tree's drip line. The protective fencing may be comprised of snow fencing, orange vinyl construction fencing, chain link fence or other similar fencing with a four-foot (4) approximate height. The protective fencing may be located within the drip line of the specimen tree for approved construction only. The fencing shall follow the delineation of the approved construction.
3.
Bark protection: In situations where a tree remains in the immediate areas of intended construction, the tree shall be protected by enclosing the entire circumference of the tree's trunk with lumber encircled with wire or other means that does not damage the tree.
4.
Construction pruning: In a case where a low hanging limb may be broken during the course of construction, the obtrusive limb may be cut. The limb shall be cut either flush to the trunk on or at the next joint of the limb. The wound shall then be sealed with pruning paint. In no instance shall pruning involve a portion of the trunk or thirty (30) percent of the entire canopy without the administrative official's prior approval.
c.
Improvement within the critical root zone of a tree: Design constraints often dictate that trees slated for preservation have some encroachment on their critical root zone. The following is the minimum design criteria which is allowed within the critical root zone of a tree. Development exceeding the criteria would put the tree at risk and therefore no longer be considered a preserved tree. In such a case replacement trees shall also be required.
1.
Grade changes: In the event that grade changes must be made around a tree or group of trees, the following should be implemented in order to maintain oxygen and water exchange within the tree's critical root zone.
i.
Minimum of seventy-five (75) percent of the critical root zone must be preserved at natural grade with natural ground cover or landscaping for the tree to be considered a preserved tree.
ii.
No cut or fill greater than two (2) inches shall be located closer to the tree trunk than one-half (½) of the radius of the critical root zone radius distance.
iii.
Increase grade: Provide an aeration system just outside the tree's drip line. A dry well located a minimum of one-half (½) of the radius of the critical root zone.
iv.
Decrease grade: Provide retaining walls outside the dripline to mitigate cuts.
2.
Boring of utilities: May be permitted under protected trees in certain circumstances. The minimum length of the bore shall be the width of the tree's canopy and shall be a minimum depth of forty-eight (48) inches.
3.
Trenching: Irrigation systems shall be designed to avoid trenching across the critical root zone of any tree.
4.
Paving: A maximum of twenty-five (25) percent of the critical root zone of a tree may be covered with impervious paving. The pavement and the cut and fill for the pavement is to not exceed one-half (½) of the critical root zone radius distance.
d.
Notes required as a part of all construction plans:
1.
All trees shown on this plan to be preserved shall be protected during construction with temporary fencing. Tree protection fences shall be installed prior to the commencement of any site preparation work (clearing, grubbing or grading).
2.
Fences shall completely surround the tree or clusters of trees. The fence shall be located at the outermost limits of the tree branches or dripline. The fence will be maintained throughout the construction project in order to prevent the following:
i.
Soil compaction in the critical root zone resulting from vehicular traffic or storage of equipment or materials.
ii.
Critical root zone disturbances due to grade changes greater than two (2) inches cut or fill, or boring which was not authorized by the city.
iii.
Wounds, to the trunk, limbs or exposed roots by mechanical equipment.
iv.
Other activities detrimental to trees such as chemical storage, cement trunk cleaning, and fires.
3.
In cases of area constraints where the protective fence is closer to the trunk than four (4) feet, the trunk must be protected with strapped-on planking to a height of eight (8) feet or to the limits of the lower branching.
4.
All grading within critical root zones of specimen trees shall be performed by hand or small equipment to minimize damage. Prior to grading, relocate the protective fencing to two (2) feet behind the grade change area.
5.
Trees most heavily impacted by construction activities should be watered deeply once a week during periods of hot and dry weather. Tree crowns should be sprayed with water periodically to reduce dust accumulation on the leaves.
6.
Trenching for landscape irrigation shall be located as far from the existing trunks as possible.
7.
Pruning to provide clearance for structures, vehicular traffic and equipment shall take place before construction begins.
(8)
Violations. Any person violating or failing to comply with any provision or requirement of this section shall be deemed guilty of a misdemeanor and, upon conviction thereof, shall without exception, be fined the maximum amount provided in this chapter.
a.
A monetary penalty of one hundred dollars ($100.00) per diameter inch of the tree(s) removed or damaged shall be assessed and paid to the City of Hurst.
b.
A separate offense shall be deemed committed upon each day during or on which each separate violation or failure to comply occurs or continues to occur and shall be punishable as such.
