<br />LANDSCAPE WELO ORDINANCE
<br />This project has been designed to comply with the criteria of the Water Efficient Landscape
<br />Ordinance - California Code of Regulations Title 23, Division 2, Chapter 2.7 § 490 - 494 ("WELO" or
<br />the "Ordinance") as adopted by the jurisdictional agency ("Agency") for this project. The following
<br />information provides data required by the Ordinance and specifically fulfills the requirements of the
<br />Landscape Documentation Package as outlined in § 492.3 of the Ordinance. Upon completion of the
<br />Project, Contractor shall be responsible for certifying compliance with the Ordinance and Agency
<br />requirements. Prior to start of Work, Contractor shall review this information and the Ordinance to
<br />establish a full understanding of the measures necessary to meet requirements of the Ordinance.
<br />Contractor shall notify the Owner of anything the Contractor feels does not meet the requirements of
<br />the Ordinance or Agency requirements. Landscape work shall not commence until such concerns are
<br />corrected to the satisfaction of all parties.
<br />LANDSCAPE ARCHITECT'S STATEMENT
<br />I have complied with the criteria of the ordinance and applied them accordingly for the efficient use of
<br />water in the irrigation design plan and the landscape design plan.
<br />SOILS MANAGEMENT REPORT
<br />This project will require significant earthwork and/or construction activity. The type of soil in the
<br />proposed landscape areas cannot be sufficiently assessed until the earthwork and construction is
<br />substantially completed. Per §492.5 paragraph (a) (2) (B) of the State Ordinance, Contractor shall,
<br />upon completion of the earthwork operations, acquire soil samples representative of all landscape
<br />areas and have the samples analyzed by an approved laboratory in accordance with §492.5
<br />paragraph (a) (1) of the State Ordinance. Contractor shall submit the approved soil laboratory's
<br />recommendations for amending the soil as appropriate for the proposed planting in a timely manner
<br />to allow for modifications to the design plans and specifications as may be required. Contractor shall
<br />amend soil in accordance with the laboratory recommendations unless otherwise directed.
<br />LANDSCAPE DESIGN PLAN
<br />See Planting Plan of this set of drawings.
<br />IRRIGATION DESIGN PLAN
<br />See Irrigation Plan of this set of drawings.
<br />GRADING DESIGN PLAN
<br />See Site Grading and Drainage Plan of this set of drawings. See also grading design plans prepared
<br />by the Civil Engineer for this project.
<br />CERTIFICATE OF COMPLETION
<br />Contractor shall be responsible of preparing and submitting the Certificate of Completion required by
<br />the Water Efficient Landscape Ordinance - California Code of Regulations Title 23, Division 2,
<br />Chapter 2.7 § 490 - 494. Refer to the Landscape Documentation Package and the information below
<br />to provide guidance on preparing the certificate. The certificate shall be prepared and submitted upon
<br />Substantial Completion. Approval of the certificate and verification by the City that the landscape and
<br />irrigation has been installed in accordance with the approved landscape and irrigation plans and the
<br />Landscape Documentation Package is required prior to Final Acceptance of the project.

<br />The schedules below are based on calculating runtime and frequency of irrigation cycles to meet the average evapotranspiration of noted seasons factoring in the rate of water delivery, plant factors,
<br />and other variables. Actual runtimes and frequency of cycles required to sustain the landscape at the desired aesthetic appearance may differ and must be adjusted to due to field observations of
<br />microclimates, slope conditions, solar exposure, and other variables. Contractor shall observe the health of the plantings during the establishment period and make adjustments necessary from
<br />observed conditions and plant health.
<br />After the establishment period it is incumbent upon the Owners and Owner's maintenance entity to observe plant health and desired aesthetic appearance and make adjustments to the irrigation
<br />schedules as may be required to satisfy their desired aesthetic appearance as well as limit water use to less than the MAWA.

<br />WATER EFFICIENT LANDSCAPE ORDINANCE WORKSHEET
<br />A regular maintenance schedule shall be set up for this project to provide healthy plants and an
<br />efficient, functional irrigation system. The following practices shall be incorporated into a regular
<br />maintenance schedule:
<br />1.Maintain irrigation system. Adjust or replace delivery system components to keep them working
<br />to meet manufacturer specifications. Repair leaks in a timely manner. Replacement products and
<br />materials shall match originally specifications, or equal..
<br />2.Review drip emitters and adjust locations as plants mature. Replace emitters as needed to
<br />adjust water delivery to each plant, as needed.
<br />3.Adjust controller as required to provide proper amount of water to each zone.
<br />4.Mow turf on a regular basis. De-thatch and aerate annually.
<br />5.Prune plantings to maintain design form (e.g.- natural, hedge) and to remove broken or dead
<br />branches. Remove suckers from tree roots on a regular basis.
<br />6.Establish a regular program of weed and pest control. Conform to any local regulations
<br />regarding use of pesticides and herbicides. Pesticides and herbicides are to be applied only when
<br />needed and by a state licensed professional.
<br />7.Re-apply mulches as needed to maintain full coverage at planting areas, retain soil moisture,
<br />and inhibit weed growth.
