5 INTRODUCTION AND DESIGN PHILOSOPHY

The City of Lancaster (City) desires to have landsc ape development in an attractive, water efficient, and high-quality manner. These landscape and irrigation design standards will enable designers and developers to clearly understand the City's intent with respect to landscape design and management.

It is the intent of these landscape and irrigation design standards not only to establish an acceptable level of quality for approval, but to achieve harmo ny with, and bring continuity to, the existing developed areas in the City.

To permit and encourage a pleasing aesthetic interaction with the environment, a landscape design should provide a variety of shapes, textures, and c olors as well as provide practical applications such as trees to produce shade and block high winds.

A well-founded design should:
• Integrate with, complement, and improve the existing permanent landscape. • Relate to and complement the architecture of structures on the site. • Mitigate erosion.
• Provide for screening of unsightly areas and noise, as well as provide for wind and sun control.
• Minimize the use of water by stressing water conservation. • Provide for a variety of design elements.
• Reflect the needs and expectations of those persons affected by the landscape. • Utilize plant material native to, or conducive to, the local environment.

The City is very concerned about proper water use management. The City requires design efforts to be conscious of water saving irrigation systems, as well as low water use plant materials.

These design standards shall apply to all single fa mily, multi-family, commercial, institutional, and industrial projects containing landscaping.

For each applicable project a Landscape Documentation Package will be submitted to the City for approval.

These Landscape and Irrigation Design Standards will be presented in the form of a Resolution to the City Council of the City and may be updated as needed by the City departments. 6 DEFINITION OF TERMS

For the purpose of carrying out the intent of these design standards, the words, phrases, and terms included herein have the meaning ascribed herein below.

“Anti-drain Valve” means a valve located under a sprinkler head to hold water in the system to prevent drainage from sprinkler heads when the system is off. “Application Rate” means the depth of water applied to a given area, m easured in inches per minute, inches per hour, or gallons per hour.
“Applied Water” means the quantity of water supplied by the irrigat ion system to the landscape.
“Backflow
Prevention Device ” means a safety device used to prevent pollution or contamination of the water supply due to the reverse flow of water from the irrigation system. “Backfill” means soil which is replaced in a hole after excava tion and placement of irrigation lines or plant materials.
“Conversion Factor” (.62) means the number that converts the maximum ap plied water allowance from acre-inches per acre per year to gallons per square foot per year. “Certificate of Completion” means the document required under by these design standards. “Certified landscape irrigation Auditor” means a person certified to perform landscape irrigation audits by a professional trade organization or other educational organization. “Certified Irrigation Designer” means a person certified to design irrigation syste ms by a professional trade organization or other educational organization. “Check valve” means a “one-way” valve that prevents water from fl owing backward though it.

Spring loaded check valves are sometimes installed inside or at the inlet of sprinkler heads. The check prevents low head drainage.
“Common Interest Developments” means community apartment projects, condominium projects, planned developments, and stock cooperatives per Civil Code Section 1353.8. “Controller” means an automatic timing device used to remotely control valves or heads to set an irrigation schedule. A weather-based controller is a controller that uses evapotranspiration or weather data. A self-adjusting irrigation controlle r is a controller that uses sensor data (i.e., soil moisture sensor).
“Development Proposal” means an application for approval of a specific pla n, subdivision, conditional use permit, site plan review, tentative tract map, parcel map or any other discretionary development permit or entitlement application which has been filed with and is pending consideration by the City.
“Drip irrigation” means any non-spray low volume irrigation system ut ilizing emission devices with a flow rate equal to or less than two (2) gallons per hour. “Drought Tolerant Plants” means plants from California and other dry areas that can survive on very little water, such as those which naturally gr ow in the high desert regions of southern California in normal rainfall years.
7 “Ecological Restoration Project” means a project where the site is intentionally alt ered to establish a defined, indigenous, historic ecosystem.
“Effective Precipitation” or “Usable Rainfall” means the portion of total precipitation that is used by the plants.
“Emitter” means a drip irrigation emission device that delivers water slowly from the system to the soil measured as gallons per hour.
“Erosion” means the transportation of soil particles, or mass movement of soil (mass wasting) by water, wind, or mechanical means.
“Engineer of Work” refers to the responsible designing professional of the respective project. “Established Landscape” means the point at which plants in the landscape ha ve developed significant roots growth into the site. Typically, most plants are established after one or two years of growth.
“Establishment period of the plants” means the first year after installing the plant in the landscape, or the first two years if irrigation will be terminated after establishment. “Estimated Applied Water Use” means the portion of the estimated total water use that is derived from applied water, as described in Appendix C, Section C4 . “Estimated Total Water Use” means the annual total amount of estimated water needed to keep the plants in the landscaped area healthy. It is ba sed upon such factors as the local evapotranspiration rate, the size of the landscaped area, the types of plants, and the efficiency of the irrigation system, as described in Appendix C, Section C3. “ET Adjustment Factor” means a factor that, when applied to reference evap otranspiration, adjusts for plant factors and irrigation efficiency, two major influences upon the amount of water that needs to be applied to the landscape. The maxi mum ETAF allowed in the MAWA equation must be equal to or below:
(A) 0.55 for residential regular landscapes areas.
(B) 0.45 for non-residential regular landscape areas.
(C) 1.0 for Special Landscape Areas.
“Evapotranspiration Rate” means the quantity of water evaporated from adjacent soil and other surfaces and transpired by plants during a specific time. “Flow Rate” means the rate at which water flows through pipes, valves, or emission devices, measured in gallons per minute, gallons per hour, or cubic feet per second. “Hardscape” means any durable surface material (pervious and no n-pervious). Hardscape shall be considered in the determination of the MAWA and storm water runoff flows. “Hydrozone” means a portion of the landscaped area having plants with similar water needs that are served by a valve or set of valves with the sam e schedule. A hydrozone may be irrigated or non-irrigated. For example, a naturalized area plan ted with native vegetation that will not need supplemental irrigation once established is a non-irrigated hydrozone. “Infiltration Rate” means the rate of water entry into the soil express ed as a depth of water per unit of time (i.e., inches per hour).
“Irrigation Efficiency” means the measurement of the amount of water beneficially used divided by the amount of water applied and is expressed as a percentage. Irrigation efficiency is derived from measurements and estimates of irrigation syste m characteristics and management practices. 8 The average irrigation efficiency used in the Estim ated Total Water use equation for purposes of this model ordinance are:
(A) 0.75 for overhead irrigation systems, and
(B) 0.81 for drip irrigation systems.
“Landscape Documentation Package” means the documents required under Title 8, Chapter 50 of the Lancaster Municipal Code (Lancaster Water Ef ficient Landscape Ordinance) and these design standards.
“Landscape Area” (LA) means all the irrigated planting areas, turfgrass areas, and water features in a landscape design plan subject to the Maximum A pplied Water Allowance calculation. The irrigated planting area does not include footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non-pervious hardscapes, and other non-irrigated areas designated for non-develo pment (e.g., open spaces and existing native vegetation). The landscape area is the sum of the landscape projects' regular landscape areas (RLA) and special landscape areas (SLA). LA = RLA + SLA..

Designated recreation areas and areas permanently and solely dedicated to edible plants, such as orchards and vegetable gardens, are subject to the MAWA with an ET adjustment factor not to exceed 1.0. “Landscape Architect” means a person who holds a license to practice landscape architecture in the State under the authority of Government Code Se ction 5615 (Landscape Architects Practice Act).
“Landscape Contractor” means a person licensed (i.e., C-27 license) by the State to construct, maintain, repair, install, or subcontract the devel opment of landscape systems and facilities per Business and Professionals Code, Section 7058 and 7059. “Landscape Irrigation Audit” means an in-depth evaluation of the performance of an irrigation system conducted by a Certified Landscape Irrigation Auditor. An irrigation audit includes, but is not limited to, inspection, system tune-up, system test with distribution uniformity or emission uniformity, reporting water waste, overspray or runoff that causes overland flow, and preparation of an irrigation schedule. The audit must be conduc ted in a manner consistent with the Irrigation Association's Landscape Irrigation Auditor Certific ation program or other U.S. Environmental Protection Agency “WaterSense” labeled auditing program. “Landscape Project” means a project, for the purposes of this ordinance , meeting the requirements under 8.50.040 of the Lancaster Municipal Code. “Landscaping” means a combination of trees, shrubs, perennial gro und covers, and artifacts, arranged in such a manner as to affect a design that follows the intent of this document. “Lateral Line” means the water delivery pipeline that supplies water to the emitters or sprinklers from the valve.

0.75 inches per hour, including drip irrigation, su bsurface drip, micro-sprinklers and similar irrigation types.
“Low Water Use Plant Material” means trees, shrubs, and ground covers that survive with a limited amount of supplemental water, as recommende d by the City’s Landscape and Irrigation 9 Design Standards, or as identified in the most rece nt edition of the following publication: Sunset Western Garden Book, Sunset Books, Lane Publishing Co., Menlo Park, California. “Main Line” means the pressurized pipeline that delivers water from the water source to the valve or outlet.
“Maximum Applied Water Allowance” means the upper limit of annual applied water for t he established landscaped area as specified by these d esign standards. It is based upon the area's reference evapotranspiration, the maximum ET Adjust ment Factor allowed, and the size of the regular landscape area (RLA) and the special landsc ape area (SLA). MAWA = (ETo) x (0.62) x [ETAF x RLA + 1.0 x SLA]
“Microclimate” means the climate of a small, specific area that ma y contrast with the climate of the overall landscape area due to wind, sun exposur e, plant density, and proximity to reflective surfaces.
“Mined Land Reclamation Projects” means any surface mining operation with a reclamati on plan approved in accordance with the Surface Mining and Reclamation Act of 1975. “Mulch” means any organic material such as leaves, bark, st raw, or compost, applied to the soil surface for the beneficial purposes of reducing eva poration, suppressing weeds, moderating soil temperature, and preventing soil erosion. Mulch inc ludes inorganic mineral materials such as rocks, gravel, or decomposed granite left loose (i.e., may be used for Fire Safe Landscaping). “Non-residential landscape” means the landscape area surrounding or associated with commercial, institutional, industrial, and public s ettings that may have areas designated for recreation or public assembly. It also includes the landscape area associated with common areas of common interest developments with designated recreational areas. “Operating Pressure” means the pressure at which an irrigation system is designed by the manufacturer to operate.

(A) very low water use plants is less than 0.1,
(B) low water use plants is 0.1 to 0.3,
(C) moderate water use plants is 0.4 to 0.6,
(D) high water use plants is 0.7 to 1.0.

Plant factors cited in this model ordinance are derived from the database “Water Use Classification of Landscape Species” (WUCOLS).
“Precipitation Rate” means the rate of application of water measured in inches per hour.

Drawings are usually based on drawings that are marked up in the field and furnished by the contractor. “Recreational Area” refers to portions of parks, playgrounds, sports fi elds, golf course, or schoolyards in public and private projects where tu rf provides a playing surface or serves other high use recreational purposes.
“Recycled Water, Reclaimed Water, or Treated Sewage Effluent Water” means treated or recycled waste water of a quality suitable for nonp otable uses such as landscape irrigation and water features. This water is not intended for huma n consumption. “Reference Evapotranspiration” or “ETo” means a standard measurement of environmental parameters that affect the water use of plants. ETo is given in inches per day, month, or year as represented in Appendix A. Reference evapotranspir ation is used as the basis of determining the MAWA so that regional differences in climate can be accommodated. “Regular landscape area” (RLA) is the portion of the irrigated landscape area that is not a special landscape area. RLA = LA -- SLA.
“Rehabilitated Landscapes” means any re-landscaping project that requires a permit, plan check, or design review and meets the requirements of this document and Title 8, Chapter 50 of the Lancaster Municipal Code (Lancaster Water Efficient Landscape Ordinance). “Root Barrier” means a physical wall buried underground to block, deflect, or control the sideways growth of tree roots.
“Runoff” means water that is not absorbed by the soil or landscape to which it is applied and flows from the landscape area. For example, runoff may re sult from water that is applied at too great a rate (application rate exceeds infiltration rate) o r when there is a slope. Grading and landscape shall be designed to minimize runoff.

C. WATER EFFICIENT LANDSCAPE WORKSHEET
A project applicant shall complete the Water Effici ent Landscape Worksheet that contains four (4) sections to meet the criteria and specific ations of the ordinance. See sample worksheet in Appendix B.

1) Section A shall contain general project information and a checklist of the required elements.
2) Section B shall contain the Water Use Efficiency St atement, which is a narrative summary of the water use efficiency practices applied in the landscape project. 20 3) Section C shall contain a water budget calculation for the project. For the calculation of the MAWA, a project applicant shall use the ETo values from Reference ETo Table in Appendix A.

The example calculations below are hypothetical to demonstrate proper uses of the equations and do not represent an existing and/or planned landscape project. The ETo values used in these calculations are historical data for planning purposes only. For actual irrigation scheduling, a project applicant shall use current reference evapotranspiration (ETo data, such as from the California Irrigation Management Information System (CIMIS) or other self-adjusting device (i.e., soil moisture sensor).

Also, monthly time steps are used for demonstration purposes only. A project applicant may use a time step of their choice (daily, weekly, biweekly, etc.) to complete these calculations.

1. Section C1 Maximum Applied Water Allowance (MAWA). The landscape project’s Maximum Applied Water Allowance shall be calculated using this equation:

MAWA= (ETo) (0.55) (LA) (0.62)
Where:

MAWA = Maximum Applied Water Allowance (gallons per year) ETo = Reference Evapotranspiration Appendix A (inches per year)

0.55 = ET Adjustment Factor (0.45 for nonresidential landscape areas) LA = Landscaped Area (square feet)

0.62 = Conversion factor (to gallons per square foot)
a. Example MAWA calculation: A hypothetical landscape project in Lancaster, California with an irrigated landscape area of 4,000 square feet. To calculate MAWA, the annual ETo value for Lancaster is 65.3 inches as listed in the Reference Evapotranspiration Table in Appendix A
MAWA = (ETo) (0.55) (LA) (0.62)
MAWA = (65.3 inches) (0.55) (4,000 square feet) (0.62)
= 89,069 gallons per year
To convert from gallons per year to hundred-cubic-feet per year =89,069/748 = 119 hundred-cubic-feet per year
(100 cubic feet = 748 gallons)

2. Section C2 Estimated amount of water expected from Effective Precipitation (Eppt.).

The City’s annual precipitation is not significant enough to count for this portion of the equation.

3. Section C3 Estimated Water Use (EWU) for a hydrozone and Estimated Total Water use (ETWU). The landscape project’s EWU for each hydrozone is calculated using the following equation:
21 Where:
(ETo) (PF) (HA) (0.62)
EWU = (IE)

EWU = Estimated total water use for a hydrozone (ga llons) ETo = Reference evapotranspiration Appendix A (inch es per month)
PF = Plant Factor
HA = Hydrozone area (square feet)

0.62 = Conversion Factor
IE = Irrigation efficiency

a. Example EWU calculations for three (3) hydrozones; the hypothetical Landscape project in Lancaster, California from the previous section. The following assumptions are made for the landscape: t here are three hydrozones – one each for high, moderate, and low water using plants; each hydrozone has the same irrigation type; and soil characteristics and slopes are uniform over the total landscape area.

Hydrozone 1 – High water use plant. The following additional assumptions are made for the high-water using plant; landscape coefficient/plant factor is 0.7, landscape area is 1,000 sq. ft., and IE is 0.75.

Where:

ETo = Reference evapotranspiration Appendix A (inch es/monthly) PWR = Plant water requirement

Hydrozone 3 – Low water use plant. The following assumptions are made:
landscape coefficient/plant factor is 0.2; landscape area is 2,000 sq. ft.; and irrigation efficiency (IE) is 0.81.

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Total ETo 2.4 2.9 4.4 5.8 7.3 8.5 9.3 8.6 6.6 4.6 2.9 2.1 65.3 PWR 0.4 8 0. 58 0. 88 1.1 6 1. 46 1. 7 1.86 1. 72 1. 32 0.92 0.5 8 0. 42 13.08 IWR 0. 59 0.7 2 1. 09 1.4 3 1.8 0 2. 10 2. 30 2. 12 1. 63 1.1 4 0.7 2 0. 52 16. 15 Total for Hydrozone 3 (= 16.15 X 2,000 sq. ft.), in ches 32,300

Where:

ETo = Reference evapotranspiration Appendix A (inch es/monthly) PWR = Plant water requirement
= (ETo) (PF)
IWR = Irrigation water requirement
= (PWR)/(IE)

b. Example calculation ETWU. The ETWU for the landscape is the sum total of estimated water uses for each hydrozone:

ETWU =  i=1 to n (EWU i)
Where:
i = hydrozone number
n = total number of hydrozones

ETWU = 61,120 inches + 32,300 inches + 32,300 inches
= 125,720 inches per year
23 To convert from inches per year to gallons per year:
= 125,720 X 0.62 = 77,946 gallons per year

Verify ETWU + Eppt is less than MAWA
77,946 + 0 < 89,069
ETWU + Eppt < MAWA, therefore water budget is acceptable.

c. Recreational areas (see definitions) and areas permanently and solely dedicated to edible plants, such as orchards and vegetable ga rdens, may require water in addition to the MAWA. A statement shall be included in the landscape design plan and the irrigation schedule designating those portions of the landscape to be used for such purposes and specifying any additi onal water needed above the MAWA. The total amount of irrigation water allo wed for these areas shall not exceed 1.0 of the ETo.

4. Section D shall contain hydrozone information for t he landscape project including a hydrozone map, hydrozone table, and hydrozone calcu lation summary. See sample worksheet in Appendix B.

D. COMPLIANCE WITH LANDSCAPE DOCUMENTATION PACKAGE

Prior to construction, the project applicant shall submit a Landscape Documentation Package to the City that meets all the criteria and specifications of this ordinance.

Questions:
1) Did you review the ordinance to learn about the criteria and specifications for landscape design plans? Yes No

2) Did you coordinate with the local agency or local retail water purveyor on the landscape design plan?

3) Which criteria and specifications did you apply to the landscape design plan?

4) Did you review the ordinance to learn about the cri teria and specifications for the irrigation design plans?

5) Did you coordinate with the local agency or local retail water purveyor on the irrigation design plan?

6) Which criteria and specifications plan did you appl y to your irrigation design plan?

7) Did you ask for assistance from the local agency/local retail water purveyor to calculate a project water budget?

8) Did you receive any water efficient landscape publications from the local agency or local retail water purveyor?

9) How will you assure the overall quality of the irri gation system?

10) How will you manage the irrigation system for optim um operation and performance?

11) How will you manage the irrigation system to respond to the changing requirement for water in the landscape?

14) Did you select plants from the City approved plant list?

SECTION C. Water Budget Calculation
S
ection C1. Maximum Applied Water Allowance
The Project’s Maximum Applied Water Allowance shall be calculated using this equation:

MAWA = (ETo) (0.55) (LA) (0.62)
MAWA
ETo
=
=
Maximum Applied Water Allowance (gallons per year)
Reference Evapotranspiration (inches per year)

0.55 = ET Adjustment Factor (0.45 for nonresidential landscape areas) LA = Landscaped Area (square feet)

0.62 = Conversion factor (to gallons)
M
aximum Applied Water Allowance = gallons
Show calculations
If the irrigation water (recycled water or blended water) has electrical conductivity equal to, or greater than, 3 deci Siemens per meter (dS/m) or 3 millimhos per centimeter (mmh/cm) or 2000 mg per liter total dissolved solids (TDS), a leaching factor of up to 10% may be included in the MAWA calculation. The leaching factor shall not exceed 10% of MAWA.

Section C2. Estimated amount of water expected from effective precipitation has been eliminated because the City of Lancaster does not receive enough reliable rainfall in any given year to utilize this information.

Section C3. Estimated Water Use for hydrozones and Estimated Total Water Use The project’s Estimated Total Water Use is calculated using the following formula:

EWU = (ETo) (PF) (HA) (0.62)
(IE)
EWU = Estimated total water use for a hydrozone (gallons) ETo = Reference evapotranspiration (inches per month)
PF = Plant Factor
HA = Hydrozone area (square feet)

0.62 = Conversion factor
IE = Irrigation efficiency

Show calculations for each hydrozone (attach additional sheets if necessary).

ETWU = I=1 to n (EWUi)

i = hydrozone number
n = total number of hydrozones
Estimated Total Water Use =
Show calculations:

Section C4. Estimated Applied Water Use section has been eliminated because the City of Lancaster does not utilize effective rainfall in these calculations

Section C5. Additional Water Requirements
Recreational areas and areas permanently and solely dedicated to edible plants may require water in addition to the Maximum Applied Water Allowance. Please be sure to provide a statement in the landscape design plan and in the irrigation sch edule, designating those portions of the landscape to be used for such purposes and specifyi ng any additional water needed above the Maximum Applied Water Allowance. The total amount of irrigation water allowed for these areas shall not exceed 1.0 of ETo.
