CERTIFICATION
Water Efficient Landscape Ordinance Irrigation Audit
Proiect Name: 4500 Roxbury Terrace Residence
Address: 4500 Roxbury Terrace
City, State Corona Del Mar, CA
This is to acknowledge that an irrigation audit has been performed in accordance with the Water Efficient
Landscape Ordinance, Components of the irrigation system were inspected for their installation and
operation and found to beacceptabie, as is generally found in similar irrigation projects. The audit
results found that the contractor met the criteria and irrigation specifications of the approved Landscape
DocumentationPackage. The Estimated Total Water Use calculated for the irrigation system meets the
Maximum Applied Water Allowance requirement and will continue to do so as long as the irrigation
system is properly maintained and managed.

RE: Soil Management Report
Rowshan Residence 4500 Roxbury Rd.
Sample Right Side of Property, 6", received June 29, 2022, Our lD No. 22-181-14
Dear Brianna,
The pH is moderately alkaline at 7.63. Limestone is present. It induces iron deficiency in
acid -loving plants.
The salinity is high at 6.14 millimho/cm. Chloride is 1,108 parts per million in the
saturation extract.
Soil is defined as being saline when salinity is over 4 millimho/cm
The fertility is high except for moderate sulfur. Nitrogen, phosphorus, potassium, iron,
manganese, zinc, copper, boron and magnesium are high. Gypsum is present. The
concentrations of common non -essential heavy metals are low.
Available sodium is moderately high. SAR (sodium adsorption ratio) is 4.9.
Ideally, SAR should be less than about 3. High sodium and high SAR values limit soil
physical properties, reduces water percolation, decreases soil aggregate stability,
increases clay dispersion, increases swelling of expandable clays, increases surface
crusting and reduces soil tilth. High sodium also restricts the uptake of competitive ions
such as potassium and calcium. Sodium and SAR can be lowered with the addition of
gypsum followed with leaching.
The texture is sandy loam. Based on the non -gravel fraction, it contains 68.61/o sand,
18.3% silt and 13.1% clay. The gravel content is 16.9%.
Soil organic matter is modest at 2.46% on a dry weight basis. The carbon:nitrogen ratio is
8.4.
The estimated rate of water percolation based on Soil Water Characteristics version
6.02.74 model developed by Keith Saxton of the USDA is moderate at 1.24 inches per
hour for normal soil compaction. The model is based on the soil texture, percent gravel
and percent soil organic matter.
Continuation, June 30, 2022, page 2
Recommendations
General soil preparation on a square foot basis. Broadcast the following uniformly; rate is
per 1,000 square feet for a 6-inch lift. Incorporate it homogeneously 6" deep.
Organic soil amendment - about 4 cubic yards, sufficient for 3% to 5% soil organic
matter on a dry weight basis
For the preparation on a volume basis, homogeneously blend the following into the soil.
Organic soil amendment - about 20% by volume, sufficient for 3% to 5% soil organic
matter on a dry weight basis
Organic soil amendment:
1. Humus material shall have an acid -soluble ash content of no less than 6% and no
more than 20%. Organic matter shall be at least 50% on a dry weight basis.
2. The pH of the material shall be between 6 and 7.5.
3. The salt content shall be less than 10 millimho/cm @ 25' C. on a saturated paste
extract.
4. Boron content of the saturated extract shall be less than 1.0 part per million.
5. Silicon content (acid -insoluble ash) shall be less than 50%.
6. Calcium carbonate shall not be present if to be applied on alkaline soils.
7. Types of acceptable products are composts, manures, mushroom composts, straw,
alfalfa, peat mosses etc. low in salts, low in heavy metals, free from weed seeds,
free of pathogens and other deleterious materials.
8. Composted wood products are conditionally acceptable [stable humus must be
present]. Wood based products are not acceptable which are based on red wood or
cedar.
9. Sludge -based materials are not acceptable.
10. Carbonmitrogen ratio is less than 25:1.
11. The compost shall be aerobic without malodorous presence of decomposition
products.
12. The maximum particle size shall be 0.5 inch, 80% or more shall pass a No. 4 screen
for soil amending.
Maximum total permissible pollutant concentrations in amendment in parts per
million on a dry weight basis:
arsenic 12
copper
100
selenium

cadmium 15
lead
150
silver

chromium 200
mercury

Higher amounts of salinity or boron may be present if the soils are to be
preleached to reduce the excess or if the plant species will tolerate the salinity
and/or boron.
Continuation, June 30, 2022, page 3
Irrigate deeply after amending the soil and leach prior to planting. Lower the SAR to less
than 3. Reduce the salinity to less than 3 millimho/cm. Reduce chloride to less than 150
parts per million in the saturation extract for salt -sensitive plants.
For maintenance fertilization, apply ammonium sulfate (21-0-0) at 5 pounds per 1,000
square feet about once per quarter.
Correct iron deficiency as needed with BASF Sprint 138 Fe or other FeEDDHA chelated
iron.
Monitor the site with periodic testing. Adjust the maintenance program as needed.
Sincerely,
Gam A. Wallace, Ph. D.
