COST ESTIMATE FORMS AND MINIMUM SPECIFICATIONS
In order to assist the developer in acquiring contractor bids and assuring a minimum level of
installation performance and aesthetic intent the following bid sheets and specifications are
provided. 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.

Entry Median Planting:
• Installation of drip (for trees) and spray (for sod) irrigation per irrigation contractor's
design.
• Install 8 entry trees at 38' -7" on center the length of the median, beginning 30' from
the northern end of the planter (Sunrise Drive end).
• Prepare surface of the planter to receive sod with 6" of topsoil raked smooth. Apply
sod to cover.

3. Founder's Square Park:
• The area of the park will be covered to a depth of 6" with topsoil
• Concrete pads for benches shall be 4" thick with 6" of V crush rock base. 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.

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.
