ZDO 1103: Open Space Review

1103.01 Applicability

Section 1103 applies to development that affects an open space resource described in Section 1011, and shown generally on Comprehensive Plan Map IV-6, North Urban Area Land Use Plan Map, as Resource Protection, Major Hazards, or Public and Community Use Open Space.

1103.02 Procedure

Open space review shall require a Type II application pursuant to Section 1307 and shall be subject to the following:

  1. The required site analysis and development plans shall be reviewed to ensure that all Comprehensive Plan policies, Ordinance, and development standards relevant to the open space resource designation are being satisfied.
  2. The probable impact of the proposed development on relevant natural systems or features, in particular on resources of area-wide significance, shall be evaluated.
  3. The potential for conservation easements, public acquisition, dedication, or any other available means of securing parts of the site as a park, trail, or other open space resource shall be evaluated.
  4. Alternative development proposals that better protect the open space resources through the appropriate use of such techniques as density transfers, commonwall structures, multistory buildings, parking structures, under-structure parking, and reduced parking requirements near transit lines,  shall be identified.  The intent of this is to assist the applicant in using the various provisions of the Comprehensive Plan, Ordinance, and development standards to achieve the best possible balance of development and open space protection.

1103.03 Approval Period And Time Extension

  1. Open space review approval is valid for four years from the date of the final written decision.  If the County's final written decision is appealed, the approval period shall commence on the date of the final appellate decision.  During this four-year period, the approval shall be implemented, or the approval will become void. 
    1. "Implemented" means all major development permits shall be obtained and maintained for the approved development, or if no major development permits are required to complete the development contemplated by the open space review approval, "implemented" means all other necessary County development permits (e.g. grading permit, building permit for an accessory structure) shall be obtained and maintained.  A "major development permit" is:
      1. A building or manufactured dwelling placement permit for a new primary structure that was part of the open space review approval; or
      2. A permit issued by the County Engineering Division for parking lot or road improvements required by the open space review approval.
  2. If the open space review approval is not implemented within the initial approval period established by Subsection 1103.03(A), a two-year time extension may be approved pursuant to Section 1310.

1103.04 Submittal Requirements

In addition to the submittal requirements identified in Subsection 1307.07(C), an application for open space review shall include:

  1. Building or manufactured dwelling placement permit submittal requirements for single-family dwellings on lots of record created prior to January 31, 1980, shall include any materials reasonably necessary for adequate review of the project's impact on the open space resource.  Examples are:
    1. A site plan showing existing natural features of the subject property and existing development, as well as proposed development, tree cutting activity, or other modification of open space re­sources; and
    2. Cross-section of any area within the open space resource where terrain modifications will occur.
  2. Submittal requirements for subdivisions and partitions shall be those identified in Section 1105, Subdivisions, Partitions, Replats, Condominium Plats, and Vacations of Recorded Plats.
  3. Submittal requirements for commercial, industrial, and multifamily developments shall be those identified in Section 1102, Design Review.

ZDO 1017: Solar Access For Land Divisions And Replats

1017.01 Applicability

Section 1017 applies to subdivisions, partitions, and Type II replats in the VR-4/5, VR-5/7, R-5, R-7, R-8.5, R-10, R-15, R-20, and R-30 Districts.

1017.02 Definitions

The following definitions apply to Section 1017:

  1. CROWN COVER: The area within the drip line of a tree.
  2. FRONT LOT LINE: A lot line abutting a street.  For corner lots, the front lot line is that with the narrowest street frontage.  When the lot line abutting a street is curved, the front lot line is the chord or straight line connecting the ends of the curve.  For a flag lot, the front lot line is the lot line that is most parallel to and closest to the street, excluding the pole portion of the flag lot.  (See Figure 1017-1.) 

    Figure of Front Lot Line 
     
  3. NORTHERN LOT LINE: The lot line that is the smallest angle from a line drawn east-west and intersecting the northernmost point of the lot, excluding the pole portion of a flag lot.  If two lot lines have an identical angle relative to a line drawn east-west, the northern lot line shall be an east-west line 10 feet in length within the lot in the northernmost point possible.  (See Figure 1017-2.)  

    Figure of Northern Lot Line
  4. NORTH-SOUTH DIMENSION: The length of a line beginning at the midpoint of the northern lot line and extending in a southerly direction perpendicular to the northern lot line until it reaches a lot line.  (See Figure 1017-3.)

     Figure of Northern Lot Line
  5. UNDEVELOPABLE AREA:  An area that cannot be used practicably for a habitable structure because of natural conditions, such as slopes exceeding 20 percent in a direction greater than 45 degrees east or west of true south, severe topographic relief, water bodies, or conditions that isolate one portion of a property from another portion so that access is not practicable to the unbuildable portion; or man-made conditions, such as right-of-way; existing development which isolates a portion of the site and prevents its further development; setbacks or development restrictions that prohibit development of a given area of a lot by law or private agreement; or existence or absence of easements or access rights that prevent development of a given area.

1017.03 Design Standard

Except as established by Subsection 1017.04, a minimum of 70 percent of the lots or parcels in the subdivision, partition, or Type II replat shall:

  1. Have a minimum north-south dimension of 90 feet.  Undevelopable area, other than a required setback area, may be included in the north-south dimension if it abuts either of the lot lines used in calculating north-south dimension; and
  2. Have a front lot line that is oriented within 30 degrees of a true east-west axis.  (See Figure 1017-4.)  

    Diagram of Solar Access design standard

1017.04 Exceptions to the Design Standard

The minimum percentage of lots or parcels that must comply with Subsection 1017.03 shall be reduced to the minimum extent necessary if one or more of the following site characteristics apply:

  1. Density and Cost:  If Subsection 1017.03 is applied, either the resulting density would be less than that proposed, the minimum density would be less than that required in Section 1012, Lot Size and Density, or on-site site development costs (e.g., grading, roads, and water, surface water management and sanitary sewer systems) are at least five percent more per lot or parcel than if the standard is not applied due to one of the following conditions:
    1. The subject property, or a portion of the subject property for which the exception is sought, has a natural grade that is sloped 20 percent or more and is oriented greater than 45 degrees east or west of true south, based on a topographic survey by a professional land surveyor registered in the State of Oregon.
    2. The subject property includes a significant natural feature identified in the Comprehensive Plan, designated open space identified in the Comprehensive Plan, a highly or moderately restricted area identified in Subsection 1012.05, or a protected water resource and associated vegetated corridor regulated by the surface water management authority, that:
      1. Prevents given streets, lots, or parcels from being oriented for solar access; and
      2. Will remain undeveloped.
    3. Existing road patterns must be continued through the subject property or must terminate on-site to comply with applicable road standards or planned roads in a way that prevents given streets, lots, or parcels from being oriented for solar access.
    4. An existing public easement or right-of-way prevents given streets, lots, or parcels from being oriented for solar access. 
  2. Development Amenities:  If Subsection 1017.03 is applied to a given lot or parcel, significant development amenities that would otherwise benefit the lot or parcel will be lost or impaired.  Evidence that a significant diminution in the market value of the lot or parcel would result from having the lot or parcel comply with Subsection 1017.03 is relevant to whether a significant development amenity is lost or impaired. 
  3. Existing Shade: As demonstrated by a scaled tree survey or an aerial photograph, trees a minimum of 30 feet tall, and more than six inches in diameter at a point four feet above grade, have a crown cover over at least 80 percent of a given lot or parcel, and at least 50 percent of the crown cover will remain after development of the lot or parcel.
    1. Trees are assumed to remain if the trees do not need to be removed for a driveway or other development and at least one of the following applies:
      1. The trees are in a required setback;
      2. The trees are part of an existing or proposed park, open space, or recreational amenity;
      3. The trees are separated from the developable remainder of their lot or parcel by an undevelopable area or feature; or
      4. The trees are required to be preserved pursuant to Subsection 1002.03(A).
    2. Those trees that are assumed to remain; required for compliance with the minimum crown cover standard of Subsection 1017.04(C); and located on the subject property, or contiguous property under the same ownership as the subject property, shall be preserved and protected pursuant to Subsection 1002.03.

In subdivisions, partitions, and replats, lots and parcels shall comply with the minimum lot size standards, if any, of the applicable zoning district, except as established by Subsections 1012.02(A) through (I).

  1. Limitation: Notwithstanding Subsections 1012.02(C) through (F), the minimum lot size inside the Portland Metropolitan Urban Growth Boundary is 20 acres in the FF-10, RA-1, RA-2, RC, RI, and RRFF-5 Districts, except as provided by Subsection 3.07.1130(c) of the Code of the Metropolitan Service District.
  2. Bonus Density: If a smaller lot size is necessary to provide bonus density dwelling units awarded under Subsection 1012.05(E), the minimum lot size standard of the applicable zoning district is waived. Demonstrating compliance with this standard shall not require the proposed development to be a planned unit development or require that townhouses be developed.
  3. Two or More Lawfully Established Dwellings on One Lot of Record: If a lot of record is not large enough to be divided in compliance with the minimum lot size standard of the applicable zoning district, the standard is waived if there are two or more lawfully established dwellings located on one lot of record with a Comprehensive Plan land use plan designation of Low Density Residential, Unincorporated Community Residential, or Rural. At least one of the lawfully established dwellings shall be located on each lot or parcel created pursuant to Subsection 1012.02(C). Subsection 1012.02(C) does not apply to the creation of separate lots or parcels for:
    1. Accessory dwelling units;
    2. Accessory historic dwellings;
    3. Accessory farm dwellings on a lot of record with a land use plan designation of Rural if the accessory farm dwelling was established after October 4, 2000;
    4. Manufactured dwellings and residential trailers established under a temporary permit;
    5. Manufactured dwellings and residential trailers established within a manufactured dwelling park or a manufactured home park;
    6. Dwellings established as a "replacement" for a historic landmark dwelling, where the continued use of the historic landmark dwelling for residential purposes was permitted as a conditional use in the HL, HD, or HC overlay zoning district; or
    7. Middle housing dwelling units; however, middle housing land divisions are permitted pursuant to Section 1105, Subdivisions, Partitions, Replats, Middle Housing Land Divisions, Condominium Plats, and Vacations of Recorded Plats.
  4. Conditional Use: If the subject property is developed, or approved to be developed, with a conditional use, the minimum lot size standards of the applicable zoning district are waived, provided:
    1. If a minimum lot size for the conditional use is established by Section 800, Special Use Requirements, it remains applicable.
    2. The proposed lot size requires approval pursuant to Section 1203, Conditional Uses. However, approval pursuant to Section 1203 does not waive the requirement to also receive approval pursuant to Section 1105, Subdivisions, Partitions, Replats, Condominium Plats, and Vacations of Recorded Plats.
    3. The minimum lot size waiver applies only to a lot or parcel developed with the conditional use and not to any other lots or parcels in the proposed subdivision, partition, or replat.
    4. A deed restriction limiting development of an undersized lot or parcel to the approved conditional use shall be recorded in conjunction with the recording of the final plat.
    5. This lot size exception does not apply in the RA-2 or RR Districts, and the minimum lot size for the lot or parcel developed with the conditional use is two acres in the RRFF-5 and FF-10 Districts. In addition, duplexes in the RA-1 District are subject to Subsection 1012.02(F) in lieu of Subsection 1012.02(D).
  5. Comprehensive Plan Boundary: If through a Type IV Comprehensive Plan map amendment, a lot of record is divided by a Comprehensive Plan land use plan designation boundary, the lot of record may be partitioned along that boundary (access strips and parcels of less than one acre are excluded). If the boundary separates an Agriculture or Forest designation from an Urban, Unincorporated Community, or Rural designation, or if the boundary separates an Agriculture designation from a Forest designation, the exception to the minimum lot size standards does not apply to any portion of the subject property designated Agriculture or Forest, except to the extent that Subsection 401.08(K) or 406.09(G) also applies.
  6. Duplexes in the RA-1 District: In the RA-1 District, there is no minimum lot size for a lot or parcel to be developed with duplexes pursuant to Section 1203, Conditional Uses. However, the maximum density standards of Subsection 1012.07 apply to the entire property proposed for development with duplexes prior to the creation of new lots or parcels.
  7. Townhouses: In the R-5, R-7, R-8.5, R-10, R-15, R-20, R-30, VR-4/5, or VR-5/7 District, the minimum lot size standards are waived for townhouses.
  8. Middle Housing Land Divisions: In the R-5, R-7, R-8.5, R-10, R-15, R-20, R-30, VR-4/5, or VR-5/7 District, the minimum lot size standards are waived for middle housing land divisions approved pursuant to Section 1105, Subdivisions, Partitions, Replats, Middle Housing Land Divisions, Condominium Plats, and Vacations of Recorded Plats.
  9. Nonresidential Tracts: The minimum lot size standards are waived for a designated nonresidential tract for a private road, open space, or similar support purpose.

1012.03 Maximum Lot Size

In subdivisions, partitions, and replats in the VR-5/7, VR-4/5, and VTH Districts, lots and parcels shall comply with the maximum lot size standards of the applicable zoning district, except as established by Subsections 1012.03(A) through (C) for the VR-5/7 and VR-4/5 Districts.

  1. A portion of the subject property may be excluded when calculating average lot size for the subdivision, partition, or replat pursuant to Note 4 or 5 of Table 315-3, Dimensional and Building Design Standards in the VR-5/7, VR-4/5, and VTH Districts, or when calculating maximum individual lot size, provided that a master plan for the excluded portion of the subject property demonstrates that the maximum lot size standards can be met for the entire property through future land division.
  2. Unless a master plan is provided pursuant to Subsection 1012.03(A), the maximum size of a lot or parcel created for a dwelling lawfully established prior to being zoned VR-5/7 or VR-4/5 is 15,000 square feet unless the dwelling is in a resource protection area, as shown on Comprehensive Plan Map X-SV-1, Sunnyside Village Plan Land Use Plan Map, in which case there is no maximum lot size standard. Such a lot or parcel is excluded when calculating average lot size for the subdivision, partition, or replat pursuant to Note 4 or 5 of Table 315-3.
  3. Resource protection area, as shown on Comprehensive Plan Map X-SV-1, is excluded when calculating average lot size for the subdivision, partition, or replat pursuant to Note 4 or 5 of Table 315-3 or when calculating maximum individual lot size.

1012.04 General Density Provisions

  1. Density is a measurement of the number of dwelling units in relationship to a specified amount of land. In the context of a partition, subdivision, replat, or manufactured home park, density typically relates to potential dwelling units in the form of lots, parcels, or manufactured home park spaces. Density often is expressed as dwelling units per acre; however, this Ordinance implements density standards in many zoning districts by assigning a district land area (DLA), which is the starting point for determining the maximum number of dwelling units allowed on a particular site. In general, the DLA is the minimum lot area required per dwelling unit; however, the DLA is subject to adjustment for density bonuses, restricted area development limitations, and limits on the extent of new road area that must be subtracted. In addition, for a duplex, triplex, quadplex, or cottage cluster in the R-5, R-7, R-8.5, R-10, R-15, R-20, R-30, VR-4/5, or VR-5/7 District, and for accessory dwelling units, DLA is not the minimum lot area required per dwelling unit.
  2. The DLA and the minimum lot size standard applicable to a particular zoning district are seldom the same. Often this is because the maximum density derived from the DLA standard is calculated over the entire site prior to any platting of new lots or parcels. The minimum lot size standard then typically permits flexibility in determining where on the site the allowed dwelling units will be developed. For example, some lots may be relatively large while others are smaller, or open space tracts may be platted while all lot sizes are relatively small. Regardless of allowed flexible sizing of individual lots or parcels, however, the maximum density allowed for the entire site remains the same.
  3. Except for middle housing land divisions approved pursuant to Section 1105, Subdivisions, Partitions, Replats, Middle Housing Land Divisions, Condominium Plats, and Vacations of Recorded Plats, if the subject property is currently developed with one or more dwelling units that will be retained, such dwelling units shall be included in demonstrating compliance with the maximum and minimum density standards of Section 1012. Notwithstanding this provision, accessory dwelling units and temporary dwellings approved pursuant to Section 1204, Temporary Permits, are not included in demonstrating compliance with the density standards, provided that these dwellings will continue to comply with the requirements for accessory dwelling units or temporary dwellings, respectively.
  4. If a subdivision, partition, or replat is proposed on property currently developed with duplexes, triplexes, quadplexes, or multifamily dwellings (or with a current design review approval for such development), maximum and minimum density shall be calculated separately for each proposed lot or parcel, except:
    1. In a planned unit development or a development of duplexes approved pursuant to Subsection 1012.07, maximum and minimum density shall be calculated for the entire property proposed for development prior to the creation of new lots or parcels.
    2. Middle housing land divisions approved pursuant to Section 1105 are exempt.
  5. In a zoning district that does not allow new detached single-family dwellings, a lot created for a nonconforming detached single-family dwelling shall not be included in the gross site area used to calculate minimum and maximum density for the remaining lot(s).
  6. Except in Urban Low Density Residential, VR-4/5, and VR-5/7 Districts, each unit in a single room occupancy is considered a dwelling unit for the purposes of calculating minimum and maximum density.

1012.05 Maximum Density

If this Ordinance establishes a district land area (DLA) for the applicable zoning district, the proposed development shall be limited to a maximum density. Except as necessary to implement a minimum lot size exception granted pursuant to Subsection 1012.02 or as established by Subsection 1012.06, maximum density shall be calculated as follows.

  1. Calculate the land area of the subject property. The result is gross site area (GSA).
  2. Subtract the following from GSA to determine net site area (NSA). In the event of an overlap between categories requiring a subtraction, the area of overlap shall be classified in the most restrictive category.
    1. The land area of new county, public, or private roads (NR) in the HR, MRR, Urban Low Density Residential, VR-4/5, VR-5/7, and VTH Districts, except:
      1. If NR exceeds 15 percent of the GSA, only 15 percent of the GSA shall be subtracted.
      2. No subtraction shall be made for strips of land adjacent to existing road rights-of-way when such strips are required to be dedicated as a condition of approval;
    2. In a zoning district other than HR and MRR, any land area of the GSA in the following highly restricted areas (HRA), except that no subtraction shall be made for HRA that will remain undeveloped, in which case density accruing to these areas may be transferred to unrestricted areas:
      1. Slopes greater than 50 percent;
      2. Mass movement hazards regulated by Section 1003, Hazards to Safety;
      3. The floodway of the Floodplain Management District regulated by Section 703, Floodplain Management District;
      4. The Willamette River and the required buffer area regulated by Section 705, Willamette River Greenway;
      5. Habitat Conservation Areas regulated by Section 706, Habitat Conservation Area District (HCAD); and
      6. Water Quality Resource Areas regulated by Section 709, Water Quality Resource Area District; and
    3. In a zoning district other than HR and MRR, fifty percent of the land area of any portions of the GSA in the following moderately restricted areas (MRA), except that no subtraction shall be made for MRA that will remain undeveloped, in which case density accruing to these areas may be transferred to unrestricted areas.:
      1. Slopes equal to or greater than 20 percent and less than or equal to 50 percent; and
      2. Areas outside the floodway but within the Floodplain Management District regulated by Section 703.
    4. In the HR and MRR Districts, any land area of the GSA in the following highly restricted area (HRA). Residential development is prohibited in the HRA.
      1. The Floodplain Management District regulated by Section 703; and
    5. In the HR and MRR Districts, 50 percent of the land area of the GSA in the following moderately restricted areas (MRA). Residential development is prohibited in the MRA.
      1. Slopes greater than 25 percent;
      2. Mass movement hazards regulated by Section 1003; and
      3. Wetlands and required buffer areas regulated by Subsection 1002.06 or another public agency.
    6. In the HR and MRR Districts, although no subtraction is required for stream corridor areas, residential development is prohibited in these areas.
  3. Divide the NSA by the DLA of the applicable zoning district. The result is base density (BD). The calculations that result in a determination of BD are represented by the following formula:

    {GSA – [NR + HRA + (MRA x 0.5)]} / DLA = BD*

    * Except in the HR and MRR Districts, HRA and MRA may be reduced to zero as provided by Subsections 1012.05(B)(2) and (3).
  4. In the MRR District, the calculation in Subsection 1012.05(C) shall be done separately for each proposed unit size category identified in Table 317-3, District Land Area Standards in the MRR District. This requires the applicant to identify the square footage of the NSA that is attributed to each unit size category. The results of each separate calculation shall be added to determine BD.
  5. Add any applicable density bonuses to BD. Bonus density shall be allowed subject to the following criteria:
    1. Unless using the affordable housing bonus under option 1 in Table 1012-1, Bonus Density, the proposed development shall include a minimum of four dwelling units, excluding accessory dwelling units and temporary dwellings approved pursuant to Section 1204, Temporary Permits.
    2. The bonus density categories and corresponding maximum increases to BD, as well as the zoning districts to which the bonus density categories are applicable, are identified in Table 1012-1, Bonus Density.
    3. In the MRR District, dwelling units allowed through the bonus density provisions shall be developed with the same unit size mixture as provided in the BD. For example, if a development is proposed with a BD of 50 units of 700 square feet and 50 units of 500 square feet, and a bonus density of 10 units is allowed, the 10 bonus units shall include 5 units of 700 square feet and 5 units of 500 square feet.

1011.03 Conflict Resolution For Wetlands And Significant Natural Areas

High-priority open space wetlands and significant natural areas shall not be disturbed unless approved through review as a Type II application pursuant to Section 1307, Procedures, for a specific commercial or industrial development plan. Approval shall not be granted unless the following social, economic, energy, and appropriate environmental considerations are addressed and satisfied:

  1. Social: The proposed development would not result in the loss of a rare, irretrievable, or irreplaceable natural feature or scientific opportunity, or the disturbance of a substantially unaltered natural feature or area in or adjacent to the proposed site, unless the benefit to the public from the proposed use clearly outweighs the public good from retaining the feature or area.
  2. Economic:
    1. The wetland or significant natural area must be disturbed for reasonable use of the site and, if not disturbed, the applicant would be substantially damaged.
    2. The use proposed is a benefit to the community and meets a substantial public need or provides for a public good which clearly outweighs retention of the wetland or significant natural area.
  3. Energy:
    1. Disturbance of the open space will not require public costs, including maintenance, due to secondary impacts, or exacerbate existing conditions.
    2. The development, as proposed, supports the Comprehensive Plan policies for energy efficient land use considering such things as transportation costs, efficient utilization of urban services, area self-sufficiency, and retention of natural features which create microclimates conducive to energy efficiency.
  4. Environmental: Disturbance of the wetland or significant natural area is minimized, as provided under Subsection 1011.02(C), and the review process and conditions of development pursuant to Section 1103, Open Space Review, and the following conditions are satisfied:
    1. Wetlands:
      1. The wetland can be altered without substantial adverse impact upon the character of the area, and function of the wetland.

1009.01 General Provisions

  1. Landscaping materials shall be selected and sited to produce a hardy and low-maintenance landscaped area with an emphasis on fast-growing plants. Selection shall include consideration of soil type and depth, spacing, exposure to sun and wind, slope and contours of the subject property, building walls and overhangs, and compatibility with existing vegetation to be preserved. Notwithstanding the requirement for hardiness, annuals are permitted as provided in Subsection 1009.01(B).
  2. A variety of plants, intermixed throughout landscaped areas, shall be provided, as follows:
    1. Evergreen and deciduous;
    2. Trees, shrubs, and groundcover;
    3. Plants of varying textures;
    4. Plants of varying widths and heights at maturity; and
    5. Plants with seasonal color interest (e.g., foliage, flowering perennials, annuals).
  3. The planting of invasive non-native or noxious vegetation shall be prohibited, and existing invasive non-native or noxious vegetation shall be removed.
  4. Landscaped areas shall not be used for other purposes, such as storage or display of automobiles, equipment, merchandise, or materials.
  5. Landscaping of the unimproved area between a lot line and the improved portion of an adjacent road right-of-way shall be required when there are no immediate plans to develop or otherwise disturb the unimproved area, and one or more of the following apply:
    1. The subject property is located inside the Portland Metropolitan Urban Growth Boundary;
    2. Landscaping is necessary to present an appearance consistent with the proposed development as viewed from the road;

1009.09 Erosion Control

  1. Graded areas shall be re-vegetated with suitable plants to ensure erosion control.
  2. Netting shall be provided, where necessary, on sloped areas while ground cover is being established.

1009.10 Planting And Maintenance

  1. Impervious weed barriers (e.g, plastic sheeting) are prohibited.
  2. Plants shall not cause a hazard. Plants over walkways, sidewalks, pedestrian pathways, and seating areas shall be pruned to maintain a minimum of eight feet below the lowest hanging branches. Plants over streets, bikeways, accessways, and other vehicular use areas shall be pruned to maintain a minimum of 15 feet below the lowest hanging branches.
  3. Plants shall be of a type that, at maturity, typically does not interfere with above- or below-ground utilities or paved surfaces.
  4. Plants shall be installed to current nursery industry standards.
  5. Plants shall be properly guyed and staked to current nursery industry standards as necessary. Stakes and guys shall not interfere with vehicular or pedestrian traffic, shall be loosened as needed to prevent girdling of trunks, and shall be removed as soon as sufficient trunk strength develops, typically one year after planting.
  6. Landscaping materials shall be guaranteed for a period of one year from the date of installation. The developer shall either submit a signed maintenance contract for the one-year period or provide a performance surety pursuant to Section 1311, Completion of Improvements, Sureties, and Maintenance, covering the landscape maintenance costs for the one-year period.
  7. Plants shall be suited to the conditions under which they will be growing. As an example, plants to be grown in exposed, windy areas that will not be irrigated shall be sufficiently hardy to thrive under these conditions. Plants shall have vigorous root systems, and be sound, healthy, and free from defects and diseases.
  8. When planted, deciduous trees shall be fully branched, have a minimum caliper of two inches, and have a minimum height of eight feet.
  9. When planted, evergreen trees shall be fully branched, have a minimum height of eight feet, and have only one leader.
  10. Shrubs shall be supplied in minimum one-gallon containers or eight-inch burlap balls with a minimum spread of 12 inches.
  11. Ground cover shall be planted a maximum of 30 inches on center with a maximum of 30 inches between rows. Rows of plants shall be staggered. Ground cover shall be supplied in minimum four-inch containers, except that the minimum shall be reduced to two and one-quarter inches or equivalent if the ground cover is planted a minimum of 18 inches on center.
  12. Plants shall be spaced so that ground coverage three years after planting is expected to be 90 percent, except where pedestrian amenities, rainwater collection systems, or outdoor recreational areas count as landscaping pursuant to Subsection 1009.02. Areas under tree drip lines count as ground coverage.
  13. Irrigation of plants shall be required, except in wooded areas, wetlands, and in river and stream buffers. The irrigation system shall be automatic, except that hose bibs and manually operated methods of irrigation may be permitted in small landscaped areas close to buildings. Automatic irrigation systems are subject to the following standards:
    1. An automatic irrigation controller shall be required for irrigation scheduling.
    2. The system shall be designed to prevent runoff, low head drainage, overspray, or other similar conditions where irrigation water flows onto non-targeted areas, such as adjacent property, non-irrigated areas, hardscapes, roadways, or structures.
    3. In mulched planting areas, the use of low volume irrigation is required to maximize water infiltration into the root zone.
    4. Narrow or irregularly shaped areas, including turf lawn, less than eight feet in width in any direction shall be irrigated with subsurface or low volume irrigation.
    5. Overhead sprinkler irrigation is prohibited within two feet of any impervious surface unless:
      1. The landscaped area is adjacent to permeable surfacing and no runoff occurs; or
      2. The adjacent impervious surfaces are designed and constructed to drain entirely to landscaping; or
      3. The irrigation designer specifies an alternative design or technology that complies with Subsection 1009.10(M)(2).
  14. Appropriate methods of plant care and landscaping maintenance shall be provided by the property owner. Pruning shall be done to current nursery industry standards.
  15. Plants shall be protected from damage due to heavy foot traffic or vehicular traffic by protective tree grates, pavers, or other suitable methods.
