The following species of trees are required to be removed and are excluded from meeting any landscape requirements: Hackberry, Chinaberry, Ashe Juniper (Cedar), Bois d' Arc, Chinese Tallow and Mesquite. The retention of any of these species must be based on the health and welfare of surrounding protected trees or groups of trees and must be approved by the City. F. Section 8.12 provides for Alternative Landscape Plan options. 8.02.010 Components of a Landscape Plan: A. Primary Landscape (Section 8.03) — A calculation of the square footage of the impervious coverage times the percentage of landscape required, see Table 8.03.010. The requirements for Primary Landscape may be satisfied by Street Trees, Parking Lot Landscape and Gateway Overlay District Landscaping, however the greater of the total calculations shall apply. (See Section 8.0 ## for Landscape Credits; credits may not be applied to other than Primary Landscape requirements. See Section 11.03 for Tree Preservation and Replacement). B. Tree Canopy (Section 8.04) — The Tree Canopy is a calculation of the percentage of the entire lot or development area based on the mature crown area of all trees. Existing and planted trees may be combined to meet the Tree Canopy requirement. Mature Tree Canopy requirements are based on Table 8.04.020. C. Street Trees (Section 8.05) — Street trees are calculated at one tree per 50 linear feet of frontage on a street. This calculation may count toward the Primary Landscape requirement. D. Parking Lot Landscape (Section 8.06) — The requirement for placement of landscape within the parking lot area is calculated on the number of parking spaces located between the building and the right -of -way and distance from the trees in accordance with Section 8.06.020 A. That calculation may count toward meeting the Primary Landscape requirements. E. Gateway Overlay District Landscape (Section 8.07) — Gateways are a zoning overlay district requirement that applies to street frontage along entry ways into our community. Gateways (See Map, Section 4.08) are established in accordance with Section 4.08. The calculations for Gateway Landscape may count toward meeting the Primary Landscape requirements. F. Bufferyards (Section 8.08) - Bufferyard requirements are based on zoning district separation. The Bufferyard calculations are a stand alone requirement and may not count toward the Primary Landscape or any other requirement. G. Screening (Section 8.09) - Screening requirements apply to Parking Lots (in addition to Parking Lot Landscaping), Mechanical Equipment (roof, ground and wall mounted), Waste Containers and Loading Docks. All screening materials must be evergreen and create a solid screen affect. Screening landscape may not count toward the Primary Landscape or any other requirement. H. Replacement (Section 8.10) - Trees identified for preservation that must be removed shall meet the replacement requirements and be reflected on the Landscape Plan. (See Section 11.03) Replacement Trees may not also count toward the Primary Landscape or any other requirement. I. Landscape Summary (Section 8.11) - A summary of the above components should be reflected in a Table. You may bracket the components that are being counted toward the Primary Landscape requirements Section 8.03 Primary Landscape 8.03.010 Primary Landscaped Area: A minimum percentage of the total lot area of property on which development, construction or reconstruction occurs after the effective date of this article shall be devoted to landscape development in accordance with the requirements. Note In single- family or two - family Residential Districts (AG, RS, RE, RL or TF), Landscaping area and Tree Canopy requirements only apply to Non - Residential uses. MU -DT District should refer to the Downtown Design Guidelines Manual See Section 4.04.020 H. and I. for MU and TOD District information Required landscaping is calculated as a percent of impervious cover, not site area. 8.03.020 Standards A. Primary Landscape Calculation: A parcel's landscaped area shall be calculated as a percentage of impervious cover. For every 600 square feet of landscape area required, two trees with a minimum 2" caliper selected from the tree list provided in Table 8.02.04.020 and four shrubs shall be planted. The total caliper calculation of trees may be substituted for the total number of trees. Calculations must be shown on the Landscape Plan. Impervious coverage _s.f. (See Section 8.03.020 B & C for credits and additions) _ _s.f. x _% (Table 8.02.03.010) _ _s.f./ 600 = _units. _Units x 2 trees = _ trees, _units x 4 shrubs shrubs. B. Landscape Credits for Primary Landscape: The following may count towards meeting the Landscaping requirements: 1. Any area improved with landscaping by the property owner as described in Section 8.03.010. 2. 25% Undeveloped land within the 100 year floodplain- restricted areas. 3. Up to 25 percent of paved parking areas where constructed with brick pavers or pervious pavement systems as approved by the Director. 4. All street trees planted within the adjacent right of way. 5.

Landscape Location: The landscaping shall be placed upon that portion of a tract or lot that is being developed. Undeveloped portions of a tract or lot shall not be considered landscaped, except as specifically approved by the Director. E. Replacement of Primary Landscape requirements: Should a tree or shrub die or be removed within 2 years of the Landscape Plan approval for which credit has been obtained pursuant to the terms of this Section, landscape development sufficient to equal the area credited shall be required. A small tree that will have a mature crown similar to the tree removed may be substituted if the planting area or pervious cover provided for the larger tree is retained. Section 8.04 Tree Canopy 8.04.010 Tree Canopy Area — Tree Canopy Area is a percentage of the entire lot square footage or development area, in accordance with Table 8.03.010. The calculation of the mature crown area of all retained and planted trees is based on Table 8.04.020. Any tree not on the tree list will be estimated by the Director using standard landscaping references The Director may approve alternate plans due to special site conditions, which may, for reasons such as safety, affect the ability to meet these regulations. 8.04.020 Standards A. Tree Canopy Calculation: The canopy is measured by computing the area that the mature canopy will encompass, based on Table 8.03.010.

Replacement of Tree Canopy requirements: Should a tree be removed withal 2 years of the Landscape Plan approval for which credit has been obtained pursuant to the terms of this Section, replacement of the trees equal to the credited shall be required. A small tree with a mature crown similar to the tree removed may be substituted if the planting area or pervious cover provided for the larger tree is retained. Section 8.05 Street Trees 8.05.010 Street Tree Requirements: Street trees must be located in the landscape easement according to the Design Standards set out in Section 12.03.020, except that up to 20 percent of street trees on a block may be planted between the sidewalk and the primary building, but within 10 feet of the sidewalk. Where poor soil conditions or other factors require additional flexibility in planting, the Planning Director may approve alternative spacing of trees, but not reduction in the number of required trees. 8.05.020 Standards A. Street Tree Calculation: Street trees must be planted at the average rate of one tree for every 50 feet of street frontage. Street trees required by this Section may be counted toward the Primary Landscape and Tree Canopy requirements. Lot frontage Linear feet (l.f.)/ 50 = # of Trees, minus _ existing trees 8.04.020 for credit) = Total # of Trees to be planted. (See Section B. Street Tree Credits: The following may be counted toward the requirements for street trees: 1. Existing trees that meet these standards may be credited as street trees. 2. Existing trees within the adjacent right -of -way may be credited as street trees. C. Tree Size and Species - Trees shall be a minimum of two caliper inches measured four and a half (4 -1/2) feet above finished grade immediately after planting.

Parking lot landscaping must meet the City's traffic safety standards as adopted in the Code of Ordinances for maintaining visibility at intersections, driveways and access easements. 8.06.020 Standards A. Parking Lot Landscape Calculation: 1. The parking lot landscape area requirements are based on the percentage of required parking located between the building fagade and the street right - of -way: a. Less than 25 percent of the parking located between the building fagade and the right -of -way requires 13 square feet of landscaping per parking stall. b. Between 25 percent to 75 percent of the parking located between the building fagade and the right -of -way requires 18 square feet of landscaping per parking stall. C, Greater than 75 percent of the parking located between the building fagade and the right -of -way requires 23 square feet of landscaping per parking stall. 2. Internal Parking Lot Landscaping - Two trees and four shrubs shall be planted for each 600 square feet of required landscape area. B. Location - All new trees within a parking lot shall be planted in a pervious area of at least 100 square feet and have a minimum interior dimension of 8.5 feet wide. However, up to 20 percent of the required trees in accordance to Section 8.02.030 may be planted in islands of at least 25 square feet and have a minimum interior dimension of five feet. C. To reduce the thermal impact of unshaded parking lots, trees shall be planted throughout parking lots so that no portion of the lot is more than 60 feet away from the trunk of a tree unless otherwise approved by the Director. < 25% =13 s.f. per parking stall 25 -75% =18 s.f. per parking stall 75 %> = 23 s.f. per parking stall _s.f. per parking stall x _number of parking stalls = _s.f. /600 = _units units x 2 trees = _# of trees units x 4 shrubs = _ of shrubs Section 8.07 Gateway Overlay District Landscape 8.07.010 Purpose and Intent - The purpose of the Landscaping Requirements for Gateways is to protect and enhance the entrance corridors to the City of Georgetown, which will: 1. Establish an entrance corridor that heralds the approach to the City; 2. Define the arrival to a destination; 3. Link common elements together; and 4. Provide consistent landscaping. 8.07.020 Applicability -Where Site Plan review is required in accordance with Section 3.09, Gateway Overlay District standards shall be applied for all properties within the specific corridors listed below. Landscaping for properties along these gateways shall comply with the requirements set forth. Gateway planting requirements may be credited toward the Primary Landscape requirements. A. Highway Gateways 1, I.H. 35 Frontage Roads both north and south; 2. Highway 195; 3.

Highway 29 (University Avenue) starting at the east portion of the Downtown Overlay District and ending at the intersection of NE Inner Loop Road ► ' ;# it ` Palge 11 of 25 5. F.M. 2338 (Williams Drive) east of the intersection of I.H. 35 and ending at the intersection with Austin Avenue, 8.07.030 Standards A. Gateway Overlay District Landscape Calculation: The Gateway Overlay District landscaped area shall be calculated by multiplying the lot width along the right -of- way times the depth of the landscape buffer. This square footage divided by 1000 determines the landscape units for calculation. _length of frontage along Gateway right -of -way x _ feet (depth of buffer) = square feet of Landscape Buffer, minus _ square feet of impervious coverage within this area = net square feet of Landscape Buffer Area. (This area is required to be 80% live vegetation with no gaps greater than 40 feet between trees or shrubbery) J 1000 square feet = _units. _units x 2 trees = trees (minus) - _existing 4 "> hardwood trees within the buffer area = net trees. units x 5 (5gal) shrubs = shrubs B. Shared Design Standards for Gateways 1. Design Standards Landscaping must comply with the remaining section of Chapter 8, Landscaping and Buffering. Where regulations and requirements for gateway corridors and the underlying zoning district conflict, the more restrictive regulations apply. 2. Site Design For all zoning districts, which require a front build -to -line provision in accordance with Table 6.03.020, the property line will be replaced with the edge of the gateway landscape easement. 3. Sidewalks Sidewalks shall be required in accordance with Table 12.03.020. All sidewalks shall be constructed and designed to coordinate the location of any new sidewalks and to tie into existing sidewalks. If the sidewalk lies within the gateway easement, a portion of the required landscaping shall be between the sidewalk and the designed right -of -way. 4. Parking No parking will be allowed within the gateway landscape buffer and all screening of parking will be in accordance with Section 8.09.010. 5. Utilities a. Drainage facilities are not allowed within the gateway landscape buffer except those that are necessary to convey drainage in the shortest possible route to or from the street right -of -way. Drainage facilities include all detention ponds, water quality ponds, outlet structures, drainage berms, improved channels, or other improvements associated with the drainage improvements. b. All detention ponds and water quality ponds within the gateway overlay district buffer shall be designed to the greatest extent possible to conform to the natural terrain of the land and if possible as curvilinear, non - rectangular shapes. Detention ponds and water quality ponds within the gateway buffer shall be designed so that the facilities do not require chain link fencing or concrete walls (or similar material). Outlet structures may be concrete. Native stone is allowed for detention ponds and water quality ponds if the ponds are located behind the gateway buffer and the stone is mortared in place or dry stacked. Gabions are now allowed. C. Fencing is allowed around detention ponds only if the fencing is constructed of wrought iron or tubular steel or other similar products. The fence shall be buffered from the street view by planting 5- gallon evergreen shrubs and vines that will at maturity, screen at least 40 percent of the view of the detention pond and fence. d. Separate ponds for each lot may be utilized if they are designed with a curvilinear contoured shape, are designed not to require fencing, are able to utilize vegetative slope stabilization with a s lope not exceeding 3:1, and no structural retaining walls are used. e. Dumpsters must be located and screened in accordance with Section 8.09.030. f. All utilities installed for the development shall be located underground. The developer shall not have to retrofit existing utilities.

Site design proposals along the Highway Gateways shall break up large masses of parking and pavement with well planned open space components. Additionally, careful analysis is required of view corridors from the highway. Strategically placed tree massings should be located to frame desired views while screening parking areas. A. Landscape Buffer A 25 landscape buffer is required and will be measured from the property line. B. Landscaping Requirements 1. The landscape buffer area shall be landscaped and maintained with at least 80% live vegetative coverage excluding the area required for driveways, sidewalks, bicycle paths, and drainage features. The remainder may be impervious landscaping such as landscape rock, native rock walls, fountains, statuary, and signs in compliance with Chapter 10 of the UDC. No fencing is allowed within the landscape buffer. 2. Trees and shrubbery are required within the landscape buffer at a ratio of at least two 2 -inch caliper shade trees and five 5- gallon shrubs for every 1,000 square feet of land. All vigorous, existing trees listed in Table 8.02.030A and /or the City of Georgetown Preferred Plant List, that are preserved shall count toward the required tree plantings if they meet or exceed the minimum of 2 inches in caliper. All trees and shrubs species shall be from the City of Georgetown Preferred Plant List, located within the Unified Development Code, Development Manual, and no more than 25% of all required trees and shrubs may be from the same species. Landscaping shall include a variety of different species and should be offset while providing informal massing and framing views. Planting offsets should be of at least 6 feet and are required for every 60 feet of continuous landscape plantings. C. Service Areas No service areas or service drives shall be permitted to front IH35, Austin Avenue, or Highway 195. 8.07.060 Scenic /Natural Gateways Scenic gateways are designated as reflecting the natural characteristics of the land. These Georgetown roadways are prominent arterials and growth zones leading into the City. The purpose of the design standards for the Scenic/Natural Gateway corridors is to maintain the informal character that currently exists as they develop. For developments which occur along the natural Scenic Gateways, designers shall integrate the natural characteristics of the land into the landscape design. Informal tree massings, planting of under story trees, incorporation of native stones and boulders and use of native grasses and wildflowers are examples of how to blend required plantings in addition to the native plantings. A. Landscape Buffer A 25' landscape buffer is required and will be measured from the property line. B. Landscaping Requirements L The landscape buffer area shall be landscaped and maintained with at least 80% live vegetative coverage excluding the area required for driveways, sidewalks, bicycle paths, and drainage features. The remainder may be impervious landscaping such as landscape rock, native rock walls, fountains, statuary, and signs in compliance with Chapter 10. No fencing is allowed within the landscape buffer. 2. Trees and shrubbery are required within the landscape buffer at a ratio of at least two 2 -inch caliper shade trees and five 5- gallon shrubs for every 1,000 square feet of land.

All trees and shrubs species shall be from the City of Georgetown Preferred Plant List, located within the Unified Development Code, Development Manual, and no more than 25% of all required trees and shrubs may be from the same species. Landscaping shall include a variety of different species and should be offset while providing informal massing and framing views. Planting offsets should be of at least 6 feet and are required for every 60 feet of continuous landscape plantings. 8.07.070 Downtown Gateways The purpose of the Downtown Gateway Corridor standards is to enhance and unify the appearance of the major roadways adjacent to, and directly leading into downtown Georgetown. Because of the close proximity to the downtown district, the appearance of the corridors shall reflect a more formal, urban extension of the downtown. In order to establish the formal appearance, trees shall be evenly spaced and located equal distance behind the property line. Intersections and parking lot entrances should be highlighted with ornamental plantings and color to visually enhance the aesthetic appearance of the higher activity zones. Although the intent for the Downtown Gateway corridors is to establish a consistent, formal landscape appearance, the design standards are not intended to adversely affect existing trees along the roadways. Variations to these standards are allowed to provide for the preservation of existing trees. A. Landscape Buffer A 15' landscape buffer is required from the designated roadway and will be measured from the property line. B. Landscaping Requirements 1. The landscape buffer area shall be landscaped and maintained with at least 80% live vegetative coverage excluding the area required for driveways, sidewalks, bicycle paths, and drainage features. The remainder may be impervious landscaping such as landscape rock, native rock walls, fountains, statuary, and signs in compliance with Chapter 10. No fencing is allowed within the landscape buffer. 2. Trees and shrubbery are required within the landscape buffer at a ratio of at least two 2 -inch caliper shade trees and five 5- gallon shrubs for every 1,000 square feet of land.
