1. 
Landscape Soil Source. All soils required for landscape beds, lawns and planting strips for the site shall be retained and stockpiled from existing site organic soils where suitable for reuse, harvested from the A and B horizons and shall meet the criteria below. Screening/sifting is not required because this process destroys soil structure and texture, specifically peds or clods, important for soil health. If on-site soils are not acceptable or available in the volume needed, similar suitable soils from off site shall be provided.
a. 
Soil shall not contain more than 25% gravel or drain rock;
b. 
Soil volume shall not be comprised of more than 25% of roots, chips or woody material. No chemicals, construction materials or foreign materials shall be allowed in the final soil;
c. 
Rock and woody materials larger than two inches diameter exposed at the surface after placement shall be raked out of the landscape and planting beds;
d. 
Soils shall be tested in a soil lab and analyzed for acceptable ranges of soil particles, nutrients, organic matter, salts and pH. Soil analysis shall include recommendations for amendments for soil to be acceptable. Soils shall be altered pursuant to the recommendations of the soil analysis; and
e. 
Soils shall be protected from compaction and heavy moisture while being stored, and should not be moved or placed in the landscape areas while saturated.
2. 
Soil Preparation in Landscape Areas.
a. 
Lawns.
i. 
Acceptable soils shall be incorporated to a minimum depth of 12 inches using a backhoe bucket with teeth. Soils should be tamped lightly to minimize excessive settling. Only the top two to four inches should be tilled, if needed, to provide a smooth surface. Soils should be tamped by hand or light equipment only. Slightly mounding the final grade is recommended to compensate for likely settling. Sod or seed as specified per the landscape plans.
ii. 
If existing soils are unacceptable, 12 inches shall be removed. The existing subgrade shall be scarified to a minimum six-inch depth with a backhoe. Six inches of acceptable soils shall be placed over the scarified subgrade, then mixed into the subgrade and tamped lightly with backhoe or other appropriate equipment. The final six inches of acceptable topsoil should be tamped lightly to minimize settling. Slightly mounding the final grade is recommended to compensate for likely settling.
iii. 
Soils shall be incorporated to the appropriate depth such that a soil probe will plunge to 12 inches without excessive resistance.
b. 
Shrub and Ground Cover Beds.
i. 
Acceptable soils shall be incorporated to a minimum depth of 24 inches using a backhoe bucket with teeth or other appropriate equipment. Soils should be tamped lightly to minimize excessive settling. Slightly mounding the final grade is recommended to compensate for likely settling.
ii. 
If existing soils are unacceptable, 18 inches shall be removed. The existing subgrade shall be scarified to a minimum six-inch depth with backhoe. Six inches of acceptable soils shall be placed over the scarified subgrade, then mixed into the final subgrade and tamped lightly with backhoe or other appropriate equipment. The final 12 inches of acceptable topsoil should be placed in two six-inch lifts and tamped lightly to minimize settling. Slightly mounding the final grade is recommended to compensate for likely settling.
iii. 
Soils shall be incorporated to the appropriate depth such that a soil probe will plunge to 24 inches without excessive resistance.
c. 
Tree Planter Strips, and Within 10 Feet of Tree Planting Locations in Planter Beds and Lawns.
i. 
Acceptable soils shall be incorporated to a minimum depth of 36 inches using a backhoe bucket with teeth or other appropriate equipment. Soils should be tamped lightly to minimize excessive settling. Slightly mounding the final grade is recommended to compensate for likely settling.
ii. 
If existing soils are unacceptable, 24 inches of soil shall be removed. The existing subgrade shall be scarified to a minimum 12-inch depth with a backhoe. The applicant shall ensure that soil excavation for amended or supplemental soils within the planter strip does not destabilize soils under the adjacent sidewalk or curb, retaining a two to one side slope of underlying structural soils adjacent to the curb and sidewalk, or as otherwise necessary to ensure structural stability. Six inches of acceptable soils shall be placed over the scarified subgrade, mixed into the subgrade and tamped lightly with a backhoe. The final 18 inches of acceptable topsoil shall be placed in two nine-inch lifts and tamped lightly to minimize settling. Slightly mounding the final grade is recommended to compensate for likely settling.
iii. 
Soils shall be incorporated to the appropriate depth such that a soil probe will plunge to 36 inches without excessive resistance.
3. 
Drainage. All landscape soils must drain. If drainage from landscape areas does not meet or exceed one-inch depth drainage in one hour, then additional drainage shall be provided.
a. 
Exemptions.
i. 
Areas exceeding a four to one slope are exempt from additional drainage requirements.
ii. 
Soils with proven natural drainage greater than one inch per hour are exempt.
b. 
Drainage, where necessary, shall consist of installing four-inch perforated pipe in linear layout or no less than 10 feet apart at the 18-, 24- or 30-inch depth, depending on the type of planting bed or strip. The trench for the pipe shall be 12 inches by 12 inches to accommodate the four-inch perforated pipe. The pipe shall be connected to a storm drain or outfall for positive flow. No filter fabric is recommended around or over the pipe. The pipe shall be covered and surrounded by four inches of drain rock on all sides. Soil preparation shall follow as described above.
E. 
Irrigation. The following section applies to all plant and soil systems that utilize an irrigation system:
1. 
Irrigation of open lawn areas is not required and is discouraged for the purposes of water conservation.
2. 
Landscape beds (areas planted with trees, shrubs, and/or groundcover), where irrigated, shall not utilize sprinkler heads, to minimize potential for overspray. Drip irrigation measures including soaker hoses and other non-spray methods are appropriate.
3. 
Any irrigation structures including control boxes, meters, booster pumps, etc., shall be located outside of public rights-of-way to provide sufficient buffer from potential vehicle damage.
4. 
Rain Barrels. Landscape and site plans are encouraged to incorporate rain barrels connected to roof downspouts into the landscape design to allow users to irrigate with roof runoff.

B. 
Maintenance Assurance. The community and economic development director shall require a maintenance assurance device and landscape maintenance agreement for a period of one years from the completion and approval of the planting in order to ensure compliance with this section, which may be held longer to accommodate appropriate planting times in the wet season for required corrections. The amount of the maintenance assurance device shall be 20% of the cost of plant materials plus installation. A maintenance assurance device and landscape maintenance agreement are not required for an individual single-family home constructed outside of a new short plat or subdivision.
C. 
Minimal Landscape Project Fee-In-Lieu of Maintenance Assurance. For projects that have a landscape project cost for plant materials and installation valued at $7,000 or less (adjusted annually for inflation from 2025), an applicant may provide a fee-in-lieu of maintenance assurance device to the city in the amount of 10% of the value of the landscaping, subject to entering a fee-in-lieu landscape agreement with the city.
(Ord. 801 § 7, 1989; Ord. 1020 (part), 1997; Ord. 1237 § 16 (part), 2005; Ord. 1256 § 1 (part), 2006; Ord. 1305 § 1 (Exh. A (part)), 2008; Ord. 1390 § 1 (Exh. A (part)), 2010; Ord. 1671 § 1 (Exh. A (part)), 2018; Ord. 1840, 10/21/2025)
The required landscaping must be installed prior to issuance of the final plat approval, issuance of a certificate of occupancy, or issuance of any other final permit necessary to approve land development or construction; provided, however, that the director in his or her sole discretion may accept a bond, letter of credit, or other performance assurance device to ensure installation of all required landscaping by such later date as determined by the director. Any such performance assurance device shall be in a form acceptable to the director and in an amount determined by the director of not less than 150 percent of the cost of all required plant materials and installation. In no case shall such performance security device be in an amount less than $1,500.
(Ord. 801 § 8, 1989; Ord. 1020 (part), 1997; Ord. 1237 § 16 (part), 2005; Ord. 1256 § 1 (part), 2006; Ord. 1305 § 1 (Exh. A (part)), 2008; Ord. 1390 § 1 (Exh. A (part)), 2010; Ord. 1671 § 1 (Exh. A (part)), 2018)
A. 
Request. An applicant may request a modification of the landscaping requirements set forth in NBMC § 18.18.060 through § 18.18.140; provided, that modifications shall not allow disturbance of protected or environmentally sensitive critical areas and that street frontage landscaping shall be maintained.
B. 
Review. The planning director may approve modifications to the standards set forth in NBMC § 18.18.060 through § 18.18.140 if the proposed landscaping is superior to that which could be achieved by strict compliance with those standards.
C. 
Findings. In approving modifications to the standards set forth in NBMC § 18.18.060 through § 18.18.140, the planning director shall prepare written findings that the proposed modification is justified based on one of the following:
1. 
The modifications retain trees equal in number to what would otherwise be required under the tree retention requirements of the clearing and grading regulations in Chapter 19.10 NBMC; or
2. 
The modifications retain existing vegetation in consolidated locations promoting the natural vegetated character of the site; or
3. 
The modifications better accommodate or improve the existing physical conditions of the subject property; or
4. 
The modifications incorporate elements to provide for wind protection, or maintain solar access or incorporate best available low impact or sustainable landscaping techniques; or
5. 
A reduction may be allowed to the perimeter landscape buffers for lots one acre in size or less that are adjacent to properties within the same zoning district or a more intensive zoning district (i.e., residential to commercial, commercial to industrial), when such buffers occupy more than 20 percent of the gross area of the lot.
(Ord. 801 § 9, 1989; Ord. 1020 (part), 1997; Ord. 1256 § 1 (part), 2006; Ord. 1305 § 1 (Exh. A (part)), 2008; Ord. 1390 § 1 (Exh. A (part)), 2010; Ord. 1671 § 1 (Exh. A (part)), 2018)
Fences shall be constructed and maintained in conformance with the following standards:
A. 
Building Permit. A building permit is required for any fence greater than six feet in height.
B. 
Review. Fence proposals for all new multifamily (triplex or larger), commercial, utility, public/quasi-public, and resource uses with buildings and/or structures shall be reviewed under the primary approval(s) required (e.g., site plan approval, design review approval, etc.).
C. 
Setbacks.
1. 
Collector and Arterial Street Setback. Fences taller than four feet in height along the property line of a collector or arterial street shall be set back a minimum of five feet off the edge of the right-of-way.
2. 
Corner Line-of-Sight Setback. For corner lots (either street or alley), or where other relevant safety considerations are present, including major driveways, any solid fences or continuous hedges that are taller than three and one-half feet in height shall be placed behind a "sight triangle" area. The sides of a sight triangle shall be two perpendicular lines each varied in length based on classification of street and measured from the edge of the vehicle travel lane of the right-of-way (either the curb or fog line) of the two intersecting streets or street and alley. The hypotenuse of the sight triangle shall be the line that crosses the corner lot and connects the two sides of the triangle. The length of perpendicular measurement shall be 30 feet for local streets, and 50 feet for collector or arterial streets. In addition, solid fences and hedges higher than three and one-half feet on corner lots shall maintain a minimum five feet side yard setback from the edge of pavement or back side of any sidewalk or open drainage ditch along the street frontage. As necessary, the community and economic development department reserves the right to utilize other methodologies in ensuring an adequate line-of-sight area for corner lots, or where other public safety considerations are present.
18.18.175(C)(2) - Figure A - Sight Triangle Area
3. 
No setbacks are required for fences along property lines other than those described above.
D. 
Height Limits. Fences in front yard areas may not be greater than six feet in height along the front property line, and within the corner line-of-sight setback, may not be greater than three and one-half feet in height, except as may be approved through an administrative adjustment to standards pursuant to Chapter 18.25 NBMC or a variance, in addition to the required building permit.
E. 
Wildlife. To allow for the movement of wildlife, fences are not permitted on the outside of perimeter landscape buffers within the TLA, or on the outside of the perimeter landscape buffer of BP zoned properties adjacent to residential zones.
F. 
Additional Standards. Additional standards for fences exist within the land use performance standards in NBMC § 18.10.050 and commercial design standards in Chapter 18.34 NBMC for certain land uses.
