  4. INTRODUCTION This document provides the designer with sufficient information to convey the Government’s goals and intent for this project concerning landscape and aesthetics issues. This is accomplished through these design guidelines which establish minimum requirements and state desired results. The structure of this document loosely follows the structure of the document entitled “WattyVos Boulevard Design Document, October 2013”. Written descriptions of design parameters and illustrative graphics are provided for each subsection. GOALS AND OBJECTIVES Major goals for the landscape and aesthetics portion of this project overlap and extend beyond the goals for the overall roadway improvement project as follows: Safety Comfort Aesthetically pleasing Unified design theme Ease of maintenance

  5. OVERALL DESIGN GUIDELINES • Safety • Vertical clearance from overhanging tree limbs • 3M over sidewalks and multi use trails • 4.5M over roadway • Ringweg 3: Horizontal clearance in 40M Section from travel lane to trees/palms • 2M from edge of lane in medians • 5.5M from edge of lane on roadside edge • Ringweg 3: Horizontal clearance in 25M Section from travel lane to trees/palms • 2M from edge of lane in medians • No opportunity for trees/palms on roadsides (needed 1.2M from face of curb) • Horizontal Clearance for other proposed roadway improvements to be determined once roadway geometry is established. • Horizontal clearance from multi use trail • 1.2M to trees/palms from edge of trail • Clear sight lines to intersecting vehicular and pedestrian traffic • Clear sight lines to roadway signs

  6. OVERALL DESIGN GUIDELINES (continued) • Comfort • Provide shade for pedestrians and bicyclists • Consider providing seating/resting areas • Aesthetics • Provide visual relief using green component of harsh roadway environment • Buffer undesirable views • Frame desirable views • Unified Design Theme • Select appropriate palette for non-irrigated areas focusing on native and endemic species • Select plants for irrigated areas that contribute to a tropical and verdant atmosphere • Ease of Maintenance • Provide guidelines for establishment and continuing maintenance

  7. PROPOSED PLANT PALLETTE A preliminary plant palette is presented. It is the result of input from Government staff, local nurserymen, research, and our experience. All proposed plants are drought tolerant. Non-irrigated areas (Segments B and C) will be supplied with water for establishment (either by water truck or by temporary irrigation systems) for sufficient time to establish plants. Many plants appropriate for use in non-irrigated areas may also thrive in irrigated areas. Areas proposed to be irrigated (Segments A, D, and roundabouts) will be supplied with a permanent underground irrigation system and are able to include a wider selection of proposed plants. Large trees Tropical Almond (Terminaliacatappa) Barba di Jongcumen/Woman’s Tongue (Albizialebbeck) Palisa Cora/Gumbo Limbo (Burserasimaruba) Paslisia Blanco (Burserakarsteniana) Mispel / Sapodilla (Manilkariazapota) Small Trees DiviDivi (Caesalpinacoriaria) Kawara Tree / Geiger Tree (Cordiasebestena) Kabrahacha (Tabebuiacaraiba) Brasil (Hymatoxylumbrasiletto) Black Olive (Bucidaburserus) Frangipani (Plumeria spp.)

  12. TURBO ROUNDABOUT 2.1 TURBO ROUNDABOUT: Landscape Description • As demonstrated in Exhibits 2.1 and 2.2, landscape design for roundabouts is intended to accentuate the decision point of roadway connections to adjacent areas as well as the transition point from area to area along Ringweg 3. Therefore, roundabouts are proposed for a higher level of landscape treatment. The intent is to produce a node that is visible from a distance, with visual interest at any vantage point. Provision of irrigation allows for a more varied, verdant and colorful landscapes including tropical trees and palms, and flowering material. • Guidelines • Per each roundabout, the following is proposed: • Includes automatic underground irrigation system (low flow for trees and shrubs, sprays for turf if used) • A total of approximately 25 to 30 trees and palms, to include some combination of the following: • Specimen palms (to count for 3 trees/palms) • Large trees • Palms • Small trees • Up to 10% coverage with landscape beds composed of shrubs, ornamental grasses, and groundcovers • Up to 10% coverage with groups of large shrubs and specimen plants • Consideration of limited sod areas

  16. SEGMENT A 3.3 SEGMENT A: Landscape Description • As demonstrated in Exhibits 3.1 and 3.2, this approximately 1,600M segment of roadway is proposed for a higher level of landscape treatment as the gateway to Aruba for visitors arriving by air. The intent is to produce a tropical and lush environment featuring palms and colorful vegetation to accentuate Aruba’s reputation as a premiere destination. The 40M typical section provides opportunities for trees and palms in the roadway medians as well as on roadsides, while honoring stated horizontal clearances. • Guidelines • Per 50M of roadway, the following is proposed: • Includes automatic underground irrigation system (low flow for trees and shrubs, sprays for turf) • A total of approximately six to seven trees, palms, or clusters, to include some combination of the following: • Specimen palms • Large trees • Palms (group of 3) • Small trees (group of 3) • 25-50% coverage with landscape beds composed of shrubs, ornamental grasses, and groundcovers • 50-75% open area, including loose groups of large shrubs/specimen plants • Consideration of Sod

  20. SEGMENT B 4.3 SEGMENT B: Landscape Description • As demonstrated in Exhibits 4.1 and 4.2, this approximately 2,800M segment of roadway is proposed for a less extensive (secondary) level of landscape treatment, reflective of this generally less developed and less populated area. The intent is to enhance the roadway environment using predominantly native and endemic vegetation to create an attractive corridor that complements the landscapes that it travels through, and that can thrive on natural rainfall after establishment. As in Segment A, the 40M typical section provides opportunities for trees and palms in the roadway medians as well as on roadsides, while honoring stated horizontal clearances. • Guidelines • Per 50M of roadway, the following is proposed: • No automatic underground irrigation system is to be provided; water for establishment will be provided by water truck or by temporary irrigation systems during the establishment period • A total of approximately four to five trees, palms, or clusters, to include some combination of the following: • Large trees • Palms (group of 3) • Small trees (group of 3) • Up to 10% of open areas to be planted with landscape beds composed of shrubs, ornamental grasses, and groundcovers • Open areas to include loose groups of shrubs, large shrubs, and specimen plants

  24. SEGMENT C 5.3 SEGMENT C: Landscape Description • As demonstrated in Exhibits 5.1 and 5.2, this approximately 1,500M segment of roadway is proposed for a less extensive (secondary) level of landscape treatment similar in intent to Segment B, with the intent roadway enhancement using predominantly native and endemic vegetation to create an attractive corridor that can thrive on natural rainfall after establishment. The typical section is narrowed to 25M, which impacts tree and palm selection and placement as follows: Honoring horizontal clearances will allow for small trees and palms in roadway medians, but will not allow trees and palms to be planted between the roadway and right of way line. No large trunked trees or palms can be planted in this segment. • Guidelines • Per 50M of roadway, the following is proposed: • No automatic underground irrigation system is to be provided; water for establishment will be provided by water truck or by temporary irrigation systems during the establishment period • A total of approximately three to four of the following: • Palms • Small trees • Up to 10 % of open areas to be planted with landscape beds composed of shrubs, ornamental grasses, and groundcovers • Open areas to include loose groups of shrubs, large shrubs, and specimen plants

  28. SEGMENT D 6.3 SEGMENT D: Proposed Roundabout at Bushiri to LG Smith/JE Irausquin • As demonstrated in Exhibits 6.1 and 6.2, this approximately 1,000M segment of roadway is proposed for a higher level of landscape treatment as the gateway to Aruba for visitors arriving by air. The intent is to produce a tropical and lush environment featuring palms and colorful vegetation to accentuate Aruba’s reputation as a premiere destination. The typical section is narrowed to 25M, which impacts tree and palm selection and placement as follows: Honoring horizontal clearances will allow for small trees and palms in roadway medians, but will not allow trees and palms to be planted between the roadway and right of way line. No large trunked trees or palms can be planted in this segment. • Guidelines • Per 50M of roadway, the following is proposed: • Includes automatic underground irrigation system (low flow for trees and shrubs, sprays for turf) • A total of approximately six to seven of the following: • Palms • Small trees • 25-50% coverage with landscape beds composed of shrubs, ornamental grasses, and groundcovers • 12-25% large shrubs and specimen shrubs • Consideration of Sod

  29. ADDITIONAL SECTION ROUTING 7.1 ADDITIONAL SECTION ROUTING Bicyle Path Low Rise Hotel Area PosAbou Intersection Punta Brabo Int. N. Costa Linda Hotel Eagle Beach Areas Ponton Widening

  30. ADDITIONAL SECTION ROUTING 7.2: Bicycle Path Safety of users on multi-use trails is the most important design consideration and informs all other decisions. This includes but is not limited to adequate vertical and horizontal clearance for trail users including bicyclists, adequate clear visibility of intersecting traffic (autos, other bicycles, and pedestrians), and clear visibility of signs (both safety and wayfinding signs). Comfort of users is next in order of importance, including provision of some shade in an overall attractive roadway environment. Placement of landscape plantings between the roadway and path is an important component in user comfort. In general, only shrubs can be planted between the roadway and trail due to horizontal clearance issues. 7.3: Low Rise Hotel Area Reconstruction of this area of roadway and multi use path running parallel to the beach provides the opportunity to enhance aesthetics and usability of this highly traveled area and encourage people to bike and walk as an alternative to the automobile. The roadway itself and further development of plans for public beach access areas should include sufficient room for trees and palms along the roadway and trail to continue the theme established with Ringweg 3. Trees and palms placed 15-20M apart on average along the beach side of the roadway should be considered where sufficient space exists.

  31. ADDITIONAL SECTION ROUTING 7.4: PosAbou Intersection this roundabout is currently not landscaped. Roadway improvements should be accompanied by landscape improvements to create one of the gateways to the hotel district. Landscape treatment should be as extensive as proposed treatment for turbo roundabouts along Ringweg 3. 7.5: LG Smith & JE Irasquin / Ringweg 3 Intersection This intersection will undergo extensive roadway and drainage improvements. Landscape enhancements should be appropriate to the hotel district tropical theme. Landscape treatment should be as extensive as proposed treatment for turbo roundabouts along Ringweg 3.

  32. ADDITIONAL SECTION ROUTING 7.6: N. Costa Linda Hotel This area is proposed to be formalized and beautified into a more permanent beach access and parking location. This area is deserving of a signature landscape treatment. Within the roadway corridor itself, palms and/or trees 15-20M on center should be planted on both sides of the roadway as space allows. Flowering shrubs and groundcovers should be planted along a minimum of 5M for every 50M of roadway. In the parking area, a maximum of 10 continuous parking spaces should be allowed. A min of 20% of open space should be provided within parking and within 2M of parking. Minimum width of landscape island shall be 2.5M and contain one tree or palm. Ground plane shall be planted or crushed shell. 7.7: Eagle Beach Areas The Eagle beach area will transform into a multi-use corridor running parallel and adjacent to hotels and beach access. This area is deserving of a signature landscape treatment. Within the roadway corridor itself, palms and/or trees 15-20M on center should be planted on both sides if the roadway as space allows. Flowering shrubs and groundcovers should be planted along a minimum of 5M for every 50M of roadway. In the parking area, a maximum of 10 continuous parking spaces should be allowed. A min of 20% of open space should be provided within parking and within 2M of parking. Minimum width of landscape island shall be 2.5M and contain one tree or palm. Ground plane shall be planted or crushed shell.

  33. ADDITIONAL SECTION ROUTING 7.8: Ponton Widening Roadway widening presents the opportunity to address aesthetics at the same time. Should sufficient space be available, Ponton should be considered for trees and palms along the roadway, with limited use of shrubs and groundcovers. Trees 20-25M apart with groups of shrubs and groundcovers along approximately 5% of the roadway edge are recommended. 7.9 Budget Considerations Typical Turbo Roundabout Segment A Segment B Segment C Segment D

  39. 8.0 Maintenance Guidelines The following is an overview of establishment period and continuing maintenance recommendations for long term health and attractive appearance of roadway landscape installations. These are offered for discussion purposes. The following operations shall be performed during the first year establishment period and shall be repeated annually for the life of the project. Fertilizer Specific fertilizer formulations/soils amendments and application rates shall be based upon soils analysis by an approved agronomic soils testing laboratory testing for, at a minimum, pH, organic content, soluble salts, and texture. Recommended applications two times per year in March and September or as specific conditions warrant. Edging Edging shall be performed as required to maintain landscape beds and mulched areas well defined. Weeding Weeds shall be immediately removed from planting areas. Weed removal shall be done manually (hand pulling) and herbicides may be utilized in problem areas. Application of herbicides shall be done with extreme caution to prevent potential damage to landscape plants. A minimum of two pre-emergent herbicide applications per year will be required.

  40. Pest Control • Provide plant material insect and disease control inspections continually and treat as necessary. • Pruning • Plant pruning (hand pruning, not shearing) shall be the primary method of shape and size control. Selective hand pruning shall be performed as necessary on all ornamental trees and shrubs to maintain the natural habit of the plant and ensure continuing health, vigor and attractive appearance. Palms shall be pruned a minimum of once per year in November or December to maintain good appearance. Remove damaged, dying and dead fronds and fruiting bodies. • Mulched areas shall be replenished as necessary to maintain 5 cm uniform depth throughout mulched areas. • Irrigation shall be routinely inspected on a regular basis monthly. Any interruptions in full coverage to all irrigated areas shall be immediately repaired.
