Plan shall be stamped by an IA Certified Irrigation Designer or a registered Landscape Architect.

7.

The following note shall be added to the plan: "A detailed irrigation plan complying with all requirements of the Millersville Zoning Ordinance shall be submitted to the City for approval prior to an application for Building Permit."

Prior to application for a building permit, detailed irrigation plans shall be submitted which show the information indicated above, as well as:

1.

Indicate piping routes, sizes, classes, and sleeves.

2.

Piping shall be installed at a minimum depth of twelve (12) inches.

3.

Indicate valve locations, flow and size.

4.

Indicate head locations, types and spray patterns. Precipitation rates shall be matched within a zone.

5.

Indicate design pressure.

6.

Ensure one hundred percent (100%) head-to-head coverage at all times and don't exceed spacing of a nozzle's range.

7.

System shall be zoned so as to not exceed the pressure and volume available at the water meter.

8.

Zone valves should be located at middle portion on zone and center feed whenever possible.

9.

Overspray of paved areas and structures shall be avoided.

10.

A rain/freeze sensor shall be installed and located where it can receive direct rainfall.

11.

Check valves and pressure regulators shall be employed to control low-head drainage and high pressure.

12.

Controller type and location shall be indicated.

13.

A backflow preventer shall be installed downstream of the meter and shall have an approved cover.

14.

Indicate meter size and location.

15.

Plan shall be stamped by an IA Certified Irrigation Designer or a registered Landscape Architect.

As an alternative to submitting a detailed irrigation plan for approval, the developer or contractor may choose to conduct a post-construction field performance audit, using the Irrigation Association's Certified Landscape Irrigation Program. The irrigation system shall meet all performance criteria listed above. The audit shall check the performance of the system for conformance with state and local requirements including meeting standards for the minimum precipitation rate and lower requirement including meeting standards for the minimum precipitation rate and lower quarter distribution uniformity (DULQ) (and where possible, emission uniformity for drip/micro-irrigation systems). In addition, the audit shall also verify the installation of specified water management devices such as a rain shutoff device. Audits shall be performed by an IA Certified Irrigation Auditor.

The following plants are recommended for use in projects submitted to the City. Plants not on this list will be evaluated on a case-by-case basis by the City's landscape architect.

The use of certain cultivars or varieties within a species may be required where needed to obtain a particular growth characteristic. For instance, Acer rubrum may be inappropriate to use near powerlines, while Acer rubrum 'Armstrong' may fit the available space.

AD.3.1

Plants shall be so trained in development and appearance as to be unquestionable superior in form, compactness, and symmetry. They shall be sound, healthy, vigorous, well branched and densely foliated when in leaf, and free of disease and insect adult eggs, pupae, or larvae. They shall have healthy, well-developed root systems and shall be free from physical damage or other conditions that would prevent thriving growth.

AD.3.2

There shall be no circling or girdling roots. Circling roots should be cut in at least one (1) place.

AD.3.3

Trees should be rooted into the root ball so that soil or media remains intact and trunk and root ball move as one when lifted, but not root bound. The trunk should bend when gently pushed and should not be loose, so it pivots at or below soil line.

AD.3.4

The point where the top-most root in the root ball emerges from the trunk shall be within two (2) inches of the soil surface. It can be exposed and visible at the soil surface. If it is not within the top two (2) inches of soil, gently remove the top layer of soil from the root ball until the first major root flare is visible.

AD.3.5

The relationship between caliper, height, and root ball size shall meet the ANSI Z60.1 standard, latest edition.

AD.3.6

There should be one (1) dominant leader to the top of the tree with the largest branches spaced at least six (6) inches apart. There can be two (2) leaders in the top ten percent (10%) of the tree if it is otherwise of good quality.

AD.3.7

The tree canopy should be symmetrical and free of large voids. Clear trunk should be no more than forty percent (40%) of tree height unless otherwise specified in the planting specifications. Clear trunk shall be of sufficient height to clear surrounding uses that may be impacted by the future growth of the tree.

AD.3.8

Open trunk and branch wounds shall be less than ten percent (10%) of the circumference at the wound and no more than two percent (2%) inches tall. Properly made pruning cuts are not considered open trunk wounds. There should be no conks or bleeding, and there should be no signs of insects or disease on more than five percent (5%) of the tree.

AD.3.9

If any of the above conditions are not met, trees may be rejected.

(Ord. No. 20-744, 6-1-2020)

AD.4.1

The depth of the hole dug should be about ten percent (10%) less than the distance from the top-most root (measured where it joins the trunk) to the bottom of the root ball. The width of the hole shall be at least two (2) times the width of the root ball.

AD.4.2

Cut away burlap and wiring so that at least one-third (1/3) of the root ball is exposed. Synthetic burlap shall be removed entirely. All twine and rope shall be removed from the base of the tree and from any branches.

AD.4.3

After planting, the topmost root shall be no more than two (2) inches below the soil surface. Additional soil should be removed. The surrounding grade should be even with or slightly lower than the top root.

Please note: some trees will arrive from the nursery with too much soil covering the first major root flare. This soil should be removed. The resulting soil line should be even with or above the surrounding grade.

AD.4.4

Three (3) inches of mulch shall be applied to cover the sides of the root ball to a point even with the dripline. Do not add any soil to the top of the root ball. Do not add any more than one (1) inch of mulch to the top of the root ball.

AD.4.5

In poorly drained soil, position the top of the root ball ten percent (10%) or more above the surrounding grade. No more than twenty percent (20%) of the root ball should be above the surrounding grade.
