Existing Conditions I. Current Condition The contractor shall take into consideration all utilities and existing conditions within the width of

the parkways in accordance with the diagrammatic layouts in this document. The contractor is to assess the existing condition of the landscaping and irrigation system currently installed. Coordinate with the city to obtain as-built drawings for point of connection information as well as current equipment, mainline, wiring/controllers, and sleeving.

II. Obtain a Soils Report

As a part of the pre-construction submittal to the city, the contractor will be responsible for obtaining an agronomic soils report from an accredited soils engineering lab in order to determine the lab recommended soil amendments for the specific site. This information is to be included in the submittal to the city before construction. For instructions on the correct way to obtain accurate samples of soil - a sample soils report has been provided in appendix i.

III. Planting Theme from the City

The City of Corona will give direction as to which planting theme to be used in the parkway. This document outlines the planting and irrigation layouts for the parkways based on their width and the City of Coronaâ&#x20AC;&#x2122;s theme selection. The next few pages outline each themeâ&#x20AC;&#x2122;s planting palette.

Pre-Construction

Once the contractor receives the planting theme and has assessed the existing conditions of the site - the contractor will submit a red line drawing over the city provided as-builts for approval by the city before construction. This document will show the city the contractor has taken into account all utilities, parkway widths, plant palette, and any other site specific conditions that may affect the demolition, irrigation, or planting methodologies - including the soil amendments recommended from the soils report. This drawing shall show the zone for each valve with gpm not to exceed the maximum gpm of the existing valve. Should the valve exceed maximum GPM - the contractor shall coordinate with city on adding a valve based on availability of stations from the controller. Each emitter is 4 GPH (0.067 GPM) and shall be installed per the Irrigation Methodologies section of this document (refer to page 9). Contractors should be aware of the maxiumum run and elevation change permitted by this drip methodology - taking this into account based on the available static water pressure. A detailed planting schedule shall be included in this drawing reflecting the City of Corona selected planting theme and quantities based upon lengths and widths of the selected parkways. The planting layouts in this document are diagrammatic, and the contractor should always take into consideration the existing utilities, trees, and conditions of the existing site when creating this plant schedule. Some areas may require hardscape elements in high pedestrian traffic areas - the City of Corona shall determine these quantities and layout.

Demolition Methodology

I. Before Demolition is Conducted The contractor shall obtain a construction permit from the City of Corona prior to construction

and call for a pre-construction meeting through the City of Corona DWP inspection sections (951) 736-2321, 48 hours prior to starting work. All survey monuments shall be protected and perpetuated in place, any disturbed or covered monuments shall be reset by a qualified registered civil engineer or a licensed land surveyor at the direction of the city engineer. It shall be the contractors responsibility to verify the location of all utilities or structures above or below ground, shown or not shown, on the plans including but not limited to: lighting, electrical wiring, catch basins/drains, drain pipes and sleeves. The contractor will be held responsible for all damage to any utilities or structures caused by his operation. The contractor is to repair and or replace damage to existing facilities not scheduled for removal to the satisfaction of the city representative. The contractor is to protect and verify with a magnetic detector in field the location of all existing electrical wires and conduit.

II. City Recommended Turf Removal Methodologies: Removal of cool-season turf (tall fescue, perennial ryegrass, Kentucky bluegrass, bentgrass, etc):

If there is no warm season turf grass mixed in to the turf, the contractor is to dig out the turf by hand or utilize sod cutters to remove all turf.

Removal of warm-season turf (bermudagrass, St. Augustine, buffalo grass, zoysiagrass, etc): This type of turf is more difficult to remove. Warm-season turf spread laterally and can have very deep roots. If you attempt to remove it with the same method as cool-season turf, it will grow back. You need to kill it with an herbicide before removing it. One of the most common herbicides used to kill warm-season turf is Glyphosate (Roundup and others). It kills plants by translocating throughout both roots and shoots of the plant. For

City of Corona Turf Removal Handbook glyphosate to be most effective it must be applied to grass that is vigorously growing and not drought-stressed. The more leaf surface area, the better absorption of the herbicide. Therefore, do not mow the grass for two to three weeks before treating. The most effective time of the year to apply glyphosate is during late summer when the plant is storing food in the roots. The least effective time of year is winter when temperatures are low and the grass is dormant. Contactor to follow label instructions and wait 7 days after applying glyphosate to remove the grass. Water turf afterwards to ensure germination of grass seeds.

All turf areas shall be excavated to a depth of twelve inches and screened or raked completely to remove rocks and non-organic materials of one inch in diameter and greater. All turf, rocks and non-organic material collected as a part of the screening and raking process shall be disposed of off-site in a legal manner.

III. Soil Amendments Before the planting is installed, the contractor will supply soil amendments based upon the recommendations from the soils report. Fertile Class â&#x20AC;&#x2DC;Aâ&#x20AC;&#x2122; top soil shall be installed as necessary to return the site finish grade to within 1â&#x20AC;? of the finish surface of the curb or sidewalk.

Hardscape Installation:

In areas where there is high foot traffic, this document outlines the methodologies to allow for crossing parkways without the damage of plant material. Stabilized decomposed granite will be installed between planters that surround the existing street trees. The borders between planter and decomposed granite shall be separated with plastic header board (refer to detail in appendix iv). In these high traffic instances the contractor shall install these hardscape elements before installation of plant material.

City of Corona Turf Removal Handbook

Irrigation Methodologies: I. Irrigation Equipment:

All standard non-drip valves shall be removed and replaced with one of the following Rain Bird drip irrigation valves kits (kits should include regulator and basket filter) and Low Volume Emitters with flex risers (dependant upon the GPM requirement) utilizing existing wires and stations to the respective controller. Boxes shall also be replaced as needed to accomodate new service valves. For 0.2 to 5 gpm For 3-15 gpm For 3-20 gpm For 15-40 gpm Low Volume Emitters Flex Riser

Rain Bird XCZ-LF-100-PRF Rain Bird XCZ-100-PRF Rain Bird XCZ-100-PRB-COM (XCZ-100-PRBR for reclaimed) Rain Bird XCZ-150-PRB-COM GPH Low Volume Emitter - 4.0 GPH (purple cap when necessary) 1/2” IH-Series Riser Tubing Pre assembled with two 1/2” MIPT UVR Male Adapters

Preserve valves where possible and cap and abandon any equipment that will not impede the new retrofitted irrigation system or the plant material being installed; otherwise clear any and all irrigation equipment unable to be utilized for the new system - return functioning valves to the city. Any valves that are replaced shall utilize existing wiring and stations with the respective controller.

II. Installation Methodology: To address maintenance issues that arise with typical polytube drip irrigation - planted areas will

be utilizing point-to-point drip emitters in parkways and medians (refer to the “Irrigation Layouts” section for diagrammatic layouts of point-to-point irrigation throughout different parkways). Trees shall be irrigated on separate valves than shrubs/ground covers. Emitters are to be 4.0 g/h by GPH Irrigation and placed in perforated pvc pipe for longevity and durability. Emitters shall be attached to the 1/2” IH-Series Riser Tubing, connected to the lateral line, and buried appropriately as shown in the details in the “Irrigation Details” (appendix iii). No excess water shall be allowed on the street or sidewalk, and contractor is to use teflon tape on all threaded fittings except on marlex fittings.

III.

Tree Irrigation

Existing street trees shall be irrigated on a separate valve as shrub/ground covers. Each street tree shall receive two emitters as shown on diagrammatic irrigation layouts.

1. Schemes with more than one layout shown are to alternate at the lengths indicated 2. Irrigation layouts are to be chosen from the planting theme based on shrub size 3. Trees shrubs are shown on the top side of the planter in diagrams - street trees will receive 2 emitters per tree (as shown)

City of Corona Turf Removal Handbook

Planting Methodologies:

I. Installation Actual planting shall be performed during those periods when weather and soil conditions

are suitable and in accordance with locally accepted practice, as approved by the city or the cityâ&#x20AC;&#x2122;s representative. Only as many plants as can be planted and watered on that same day shall be distributed in a planting area. Containers shall be opened and plants shall be removed in such a manner that the ball of earth surrounding the roots is not broken and they shall be planted and watered as herein specified immediately after removal from the containers.

II. Weed Control

After soil preparation and establishment of final grades prior to any planting, the Contractor shall irrigate thoroughly for a period of time, two to three weeks, or until the weed seeds have germinated. When there is sufficient weed seed germination, the Contractor shall apply a post-emergent contact weed killer according to the directions of the manufacturer. The Contractor shall then wait an additional two(2) weeks to allow the weed killer to dissipate, then plant as indicated in the plans and specifications. Contractor shall remove any residual foliage and/or roots. Recommended herbicides: Dimension or Ronstar.

III. Planting Trees and Shrubs Excavation for planting shall include the stripping and stacking of all acceptable topsoil

encountered within the areas to be excavated for trenches, tree holes, plant pits, and planting beds. Excess soil generated from the planting holes shall not be used as back fill or in establishing the final grades. Protect all areas from excessive compaction when trucking plants or other materials. Center plant in pit or trench and face fullest growth into prevailing wind. Set plant plumb and hold rigidly in position until soil has been tamped firmly around ball or roots - 8 parts on site topsoil - 2 parts organic amendment per soils report. All plants which settle deeper than specified above shall be raised to the correct level. After the plant has been placed, additional back fill shall be added to the hole to cover approximately one-half of the height of the root ball of approved soil amendment material. At this stage, water shall be added to the top of the partly filled hole to thoroughly saturate the root ball and adjacent soil. Can Removal: Cut cans on two sides with an acceptable can cutter. Do not injure root ball. Do not cut cans with spade or axe. Carefully remove plants without injury or damage to root ball. After removing plant, superficially cut edge-roots with knife on three sides. Contractor is to abide by any guidelines or standards regarding distances from utilities, signage, and sight triangles. As these distances and requirements will change depending upon the site - the contractor is to ensure that all these distances take precedent over the diagrammatic planting layouts mentioned in this handbook. Dig planting holes to accommodate root balls per these specifications and hand place plants which are in containers less than one gallon in size. Hand back fill and hand tamp leaving a slight depression around the bases of plants. After the water has completely drained, quantity of planting tablets shall be:1 gallon container - one tablet, 5 gallon container - three tablets, 15 gallon container - six tablets. The remainder of the hole shall then be back filled. Planting tablets shall be set with each plant

City of Corona Turf Removal Handbook

Planting Methodologies (cont):

on the top of the root ball while the plants are still in their containers so the required number of tablets to be used in each hole can be easily verified. After back filling, an earthen basin shall be constructed around each plant. Each basin shall be a depth sufficient to hold at least two inches of water. Basins shall be of a size suitable for the individual plant. In no case shall the basin for a fifteen-gallon plant be less than four feet in diameter, five gallon plant less than three feet in diameter, and one gallon plant less than two feet in diameter. The basins shall be constructed of amended back fill materials.

IV. Mulch All planter areas are to receive a three inch layer of medium grind bark mulch under shrubs and a 1-1/2â&#x20AC;? layer of bark mulch at ground cover areas.

V. Pruning Pruning shall be limited to the minimum necessary to remove injured twigs and branches and to

compensate for loss of roots during transplanting, but never to exceed one-third of the branching structure.

1. Schemes with more than one layout shown are to alternate at the lengths indicated 2. Plants are to be chosen from the planting theme based on shrub size 3. The planting theme shall be consistent and not switch between themes 4. The city shall select the planting theme for the project 5. All planting plans shall accommodate existing street trees (street trees now shown above)
