TABLE A
Appendix A. Calculating an Annual Water Budget
An annual water budget is the target maximum amount of water a landowner should use in a typical watering season. This target provides simple-to-achieve, realistic goals for landscape irrigation. Water budgeting focuses less on watering time limits, and is more concerned with a user's water allotment and reducing over-watering. This form can help any user create a target annual water budget from which to work.
The information below will help guide you through the annual water budget worksheet on the following page.
Step 1. Gallons of Water Needed by Plant Category:
Different plants have different water needs. A plant list that identifies the water needs of landscape plants (high, moderate, low, very low) is available in the planning and building department.
Due to variability in plant water requirements due to location of the plant on a site, a range of hydrozone categories has been shown for many plants. For purposes of calculating the water budget for each hydrozone, the lowest hydrozone category for each plant shall be used.
Step 2. Irrigation Areas (Zones) Based on Plant Water Need Category:
Both automatic irrigation systems and hand-placed yard sprinklers deliver water to plants by watering areas or "zones", and have set watering amounts determined by you, the user. If you have high water need plants within low or very low water plant groupings, the entire area must be considered a high-water area and irrigated as such; however some plants may be over-watered if this occurs. The area of each watering zone can be determined by physically measuring the zone, and multiplying length (in feet) by width (in feet). The resulting areas (in square feet, or S.F.) can be entered in Step 3 below.
Step 3. Water-Use Calculations:
Fill in the blanks with area and water need per zone. For example, you might have an area of 300 S.F. in a High Water Zone that would require 20 gallons of water per S.F. After multiplying you would find that area requires 6,000 gallons of water per season.
After calculating the irrigation needs of all areas, determine your average overall water needs per season. To do this, add the total gallons needed for all zones, and divide by the total square footage for all zones. The average for the overall site must be no more than 15 gallons per S.F. per season. If your average is more than this, you must modify your planting layout to create more low/very low water zones that would balance your high/moderate water zones, and reduce over-watering.

Ten (10) percent of the total value of the escrow, letter of credit or other financial guarantee provided to the city pursuant to section 26-17-6(b)(5) of this Code shall be retained by the city during the warranty period. The final one and one-half (1.5) inch top lift of asphalt paving shall be installed only after the construction of all structures that may be built within a subdivision or particular filing thereof is complete or after the initial three-year warranty period has expired, whichever is last to occur. After the expiration of the three-year warranty period, the city engineer may, at his discretion, approve the construction of the final one and one-half (1.5) inch top lift of asphalt on a street-by-street basis upon finding that substantially all of the structures have been built, the occupants of which are likely to use the street in question. The final one and one-half (1.5) inch lift of asphalt shall also have a three-year warranty period for which ten (10) percent of the total value of the escrow, letter of credit or other financial guarantee applicable to the one and one-half (1.5) inch lift shall be retained by the city during the warranty period. The subdivider/developer shall be responsible for requesting an initial inspection of all public improvements to begin the warranty period, and a final inspection of all public improvements at the end of the three-year warranty period. At the subdivider's/developer's request, the city engineer shall make an inspection of the public improvements. When the city engineer finds that the public improvements meet city standards, the city engineer or public works director shall, by way of a written letter to the subdivider/developer, acknowledge the acceptance of the public improvements and authorize the reduction or elimination of the escrow, letter of credit or other financial guarantee, which shall occur after the three-year warranty period. Any repairs to or replacements of public improvements made by the subdivider/developer at the end of the three-year warranty period, including but not limited to repairs or replacements necessitated by damage due to construction traffic or activities, shall themselves be warranted for a period of three (3) years from the date of repair or replacement and an escrow, letter of credit or other financial guarantee acceptable to the city attorney shall be provided to the city, in an amount equal to ten (10) percent of the value of such repairs or replacements, for such three-year period.
(b)
The city council hereby ratifies and affirms all previously approved escrows, letters of credit or other financial guarantees for public improvements along with any development agreements, requirements or any conditions of approval heretofore entered into by the city and expresses its intent that the adoption of this section not affect the validity of such preexisting contracts, requirements or conditions.

TABLE A
Appendix A. Calculating an Annual Water Budget
An annual water budget is the target maximum amount of water a landowner should use in a typical watering season. This target provides simple-to-achieve, realistic goals for landscape irrigation. Water budgeting focuses less on watering time limits, and is more concerned with a user's water allotment and reducing over-watering. This form can help any user create a target annual water budget from which to work.
The information below will help guide you through the annual water budget worksheet on the following page.
Step 1. Gallons of Water Needed by Plant Category:
Different plants have different water needs. A plant list that identifies the water needs of landscape plants (high, moderate, low, very low) is available in the planning and building department.
Due to variability in plant water requirements due to location of the plant on a site, a range of hydrozone categories has been shown for many plants. For purposes of calculating the water budget for each hydrozone, the lowest hydrozone category for each plant shall be used.
Step 2. Irrigation Areas (Zones) Based on Plant Water Need Category:
Both automatic irrigation systems and hand-placed yard sprinklers deliver water to plants by watering areas or "zones", and have set watering amounts determined by you, the user. If you have high water need plants within low or very low water plant groupings, the entire area must be considered a high-water area and irrigated as such; however some plants may be over-watered if this occurs. The area of each watering zone can be determined by physically measuring the zone, and multiplying length (in feet) by width (in feet). The resulting areas (in square feet, or S.F.) can be entered in Step 3 below.
Step 3. Water-Use Calculations:
Fill in the blanks with area and water need per zone. For example, you might have an area of 300 S.F. in a High Water Zone that would require 20 gallons of water per S.F. After multiplying you would find that area requires 6,000 gallons of water per season.
After calculating the irrigation needs of all areas, determine your average overall water needs per season. To do this, add the total gallons needed for all zones, and divide by the total square footage for all zones. The average for the overall site must be no more than 15 gallons per S.F. per season. If your average is more than this, you must modify your planting layout to create more low/very low water zones that would balance your high/moderate water zones, and reduce over-watering.

Curb, gutter and sidewalks shall be installed on all streets unless otherwise approved by city council. In cases where an existing street which has not been brought up to city specifications is located within a subdivision, such street shall be paved and curb, gutter and sidewalk and other improvements shall be installed in order to meet city specifications. If any subdivision is located adjacent to any existing street right-of-way, the developer shall develop such street with improvements as required to bring such street up to city specifications. The developer shall provide and install street signs at all street intersections and traffic control signs as requested by the city traffic engineer. Permanent reference monuments and monument boxes shall be installed by the developer to city specifications, as shall bicycle paths where required by city. Street lights when required by the city shall be installed by the developer.

All public improvements shall have a three-year warranty time, beginning on the day that the city has made an initial inspection and found that all public improvements, including but not limited to streets, utilities and fiber optic conduits, to the extent that such conduits are to be owned and maintained by the city, except the final one and one-half (1.5) inch top lift of asphalt, have been installed to city specifications. Ten (10) percent of the total value of the escrow, letter of credit or other financial guarantee provided to the city pursuant to section 26-17-6(b)(5) of this Code shall be retained by the city during the warranty period. The final one and one-half (1.5) inch top lift of asphalt paving shall be installed only after the construction of all structures that may be built within a subdivision or particular filing thereof is complete or after the initial three-year warranty period has expired, whichever is last to occur. After the expiration of the three-year warranty period, the city engineer may, at his discretion, approve the construction of the final one and one-half (1.5) inch top lift of asphalt on a street-by-street basis upon finding that substantially all of the structures have been built, the occupants of which are likely to use the street in question. The final one and one-half (1.5) inch lift of asphalt shall also have a three-year warranty period for which ten (10) percent of the total value of the escrow, letter of credit or other financial guarantee applicable to the one and one-half (1.5) inch lift shall be retained by the city during the warranty period. The subdivider/developer shall be responsible for requesting an initial inspection of all public improvements to begin the warranty period, and a final inspection of all public improvements at the end of the three-year warranty period. At the subdivider's/developer's request, the city engineer shall make an inspection of the public improvements. When the city engineer finds that the public improvements meet city standards, the city engineer or public works director shall, by way of a written letter to the subdivider/developer, acknowledge the acceptance of the public improvements and authorize the reduction or elimination of the escrow, letter of credit or other financial guarantee, which shall occur after the three-year warranty period. Any repairs to or replacements of public improvements made by the subdivider/developer at the end of the three-year warranty period, including but not limited to repairs or replacements necessitated by damage due to construction traffic or activities, shall themselves be warranted for a period of three (3) years from the date of repair or replacement and an escrow, letter of credit or other financial guarantee acceptable to the city attorney shall be provided to the city, in an amount equal to ten (10) percent of the value of such repairs or replacements, for such three-year period.
(b)
The city council hereby ratifies and affirms all previously approved escrows, letters of credit or other financial guarantees for public improvements along with any development agreements, requirements or any conditions of approval heretofore entered into by the city and expresses its intent that the adoption of this section not affect the validity of such preexisting contracts, requirements or conditions.

The city may give the subdivider or developer credit for private recreation facilities in the development, provided that:
(a)
The amount of land to be dedicated may be reduced by no more than fifty (50) percent of the requirements of this chapter. No portion of the land credit will be given for required drainage detention areas.
(b)
The city council determines that the private recreation facilities offered will absorb a major portion of the recreational demands of the residents or employees of the proposed development.
(c)
The private recreation facilities will be constructed at the same time as or prior to the housing, industrial or commercial facilities in the development.
(d)
There are sufficient guarantees in the development agreement to ensure that the private recreation facilities are completed at the same time as or before the remainder of the development.
(Ord. No. 1986-01, § 2, 2-4-86)
(a)
If the city council, in its sole discretion, determines that there is insufficient, suitable land available within the subdivision to meet the dedication requirement of section 26-19-19 of this chapter, the subdivider or developer shall be required to pay to the city cash, or transfer other suitable property, in lieu of land dedication requirements. Such cash payment shall be in an amount equal to the fair market value of the property that was to be dedicated pursuant to section 26-19-20 of this chapter. If the city council determines to accept other property instead of, or as a partial payment toward the cash payment hereunder, the fair market value of the other property shall be used as the basis of the satisfaction of the requirement.
(b)
A payment in lieu of land dedication shall be made prior to final approval of the subdivision, and such payment shall be used for the acquisition of land and for the improvement of parks, playgrounds and recreation areas in the city, which may benefit the residents of the city in general, as well as those of the proposed subdivision.
(Ord. No. 1986-01, § 2, 2-4-86; Ord. No. 2007-38, § 1, 9-4-07; Ord. No. 2017-4, § 2, 3-7-17)

(c)
Land reserved shall be purchased by the public agency at its fair market value according to the following schedule:
(1)
Within ninety (90) days following approval of the final plat, the requesting agency and the subdivider or developer shall enter into an option agreement for a period of no greater than one (1) year, with a renewal provision for one (1) additional year, unless other terms are mutually agreed upon between the developer and the requesting agency.
(2)
When the option is signed, the public agency shall deposit with an escrow agent an amount which shall be determined by the public agency and the developer to equal the actual costs and expenses of replatting the subdivision if the option is not exercised, plus ten (10) percent. In the event the public agency and developer cannot agree upon the estimated expenses, the city administrator shall make the determination. In the event the option is extended for an additional year, the public agency shall deposit an additional ten (10) percent of the estimated costs and expenses with the escrow agent.
(3)
For the purpose of this section, the fair market value of the land reserved shall be the value of the raw, undeveloped land, plus a proportionate share, as they benefit the reserved land, of the actual cost of the improvements required of the subdivider or developer.
(4)
In the event the public agency and the subdivider or developer cannot agree as to the fair market value, the parties shall submit the matter to binding arbitration, under such rules and regulations as prescribed by the American Arbitration Association.
(Ord. No. 1986-01, § 2, 2-4-86)
