Bid sheets and specifications for the project are arranged by phase and further subdivided into specific areas within each phase. Each of these areas has a spread sheet, installation specifications and design assumptions which describes the landscape components specific to that area. PHASE I PROJECT COMMON AREAS With the exception of irrigation points of connection and mainline piping for common areas, it is assumed that Phase I landscaping of these common areas will commence after the completion of project infrastructure, including water, sewer, wire and road improvements. Phase I landscaping includes the following: Sunrise Drive Planting, Entry Boulevard Median, Founders Park and all areas disturbed by infrastructure installation which will require an interim revegetation effort to prevent wind and water erosion of bare ground. Specifications for these areas are as follows. Specifications: 1. Revegetation of disturbed areas with a temporary cover crop: • An appropriate quick cover seed, any one of those listed or comparable. • Surface preparation: hard packed or caked soil shall be scarified or disked. • Broadcast seed to the specified rate and rake over to set seed. Quick Cover for Erosion Control of Disturbed Soils Use any one of the species listed below at the given Tate. Common Name Botanical Name Application Rate lbs PLS/acre Percent Mix.'

Two pads are located on each of the east, west and south sides of the park abutting the inner margin of the sidewalk and will be constructed to a size that permits 3' of free space on all sides of the benches for access. Example: a pad 12' long by 8'wide would accommodate a 6' by 2' bench. Bench type shall to be determined by the developer. • Another concrete pad of the same construction shall be constructed centered on the inside of the south sidewalk of the park as shown in the drawings. This pad shall be 10' x 24' in size and will accomodate the flagpole and memorial marker. • Benches, flagpole and park memorial shall be installed according to manufacturer's instructions. • The area of the park will be sodded and have head to head spray irrigation. • The planting strip surrounding the park area, outside the sidewalk area shall be prepared and planted as a sodded area. Trees for the park planting strip will be 10 Maples and 9 Green Ash trees alternated and spaced as drawn on Sheet Ll. Trees alternate such that no two trees planted next to one another are the same species in the street planting strips. PHASE 2 Specifications: 1. Revegetation of disturbed areas with cover crop: • An appropriate quick cover seed mix such as shown above or comparable. • Surface preparation: hard packed or caked topsoil shall be scarified or disked. • Broadcast seed to the specified application rate and rake over to set seed. 2. Activity Park • The 5' wide path shall be laid out and constructed of a 2" Asphalt mat over a 6" crushed gravel base 7 ft wide. • Concrete pads (9'x17') for the lean-to shelters, 4" thick over a 6" crushed gravel base. A pedestal type barbecue shall be installed on each of the 3 pads at the time of construction and placed according to the design plan. • Lean-to shelter shall be constructed to cover an area of 10' by 12'and shall be an open air, shed type construction. • The remaining area of the park will be covered to a depth of 6" with topsoil • The Picnic/Play area of the park will be sodded and have head to head spray irrigation. Drip irrigation for shade trees and screening shrubs will be the responsibility of the irrigation contractor. Temporary irrigation will be provided to establish the permanent native grass mix in the activity area of the park. • One shade tree and 3 Lilacs will be planted near each picnic pad and screening shrubs (Pea Shrubs) will be planted along residential lot margins and as indicated on Sheet Ll. • The planting strip on the south east margin of the park area, outside the sidewalk area shall be prepared and planted as the sodded planting strips. Plant materials for the park planting strip will be 2 Maples and 2 Green Ash trees alternated and spaced as indicated on Sheet Ll. • The Activity areas will be prepared for permanent planting by smoothing or raking. Hard packed or caked topsoil shall be scarified or disking prior to seeding. Broadcast field grass seed to the specified pure live seed application rate and lightly rake over to set seed. PHASE 3 Specifications: 1. Revegetation of disturbed areas with cover crop: • An appropriate quick cover seed mix such as shown above or comparable. • Surface preparation: hard packed or caked topsoil shall be scarified or disked. Broadcast seed to the specified application rate and rake over to set seed. 2.

Broadcast field grass seed to the specified pure live seed application rate and lightly rake over to set seed. • The planting strip on the south margin of the park, outside the sidewalk area shall be prepared and planted as the entry median. Trees for the park planting strip will be 1 Green Ash tree placed as shown on Sheet Ll. • Install bollards per manufacturer's specifications. INDIVIDUAL LOT LANDSCAPING Landscaping of individual project lots will commence after the completion of each home. Likewise, the irrigation and plant materials (sod and street trees) designed for the frontage of each lot will be installed after the completion of each home. An escrow fund or surety shall be arranged between the developer and individual lot owner at the time of sale for each lot and shall be in an amount sufficient to purchase, install and irrigate all required plant material for each individual lot as specified by the City of Rexburg Development Code, Chapter 4.15, K., 7. and as indicated for all planting strip areas as described on Sheet Ll and supporting Bid Sheets and Specifications. The developer will complete the street improvements including paving, curb and sidewalk within each phase of development. It is anticipated that development of residential structures on small individual lots will require all of the space from the back of curb to the lot lines. Therefore street trees and sod will not be installed in the planting strip until each home is completed. Planting strip vegetation will be irrigated by associated individual residential irrigation systems. • Approved Planned Unit Development requirements for each lot include: two 2" caliper shade trees in each front yard; one 1.5" caliper shade tree in each back yard; and four shrubs on each lot.
