Table 30.25.016(4)

Measuring Tree Canopy

Existing Canopy

New Canopy

Option 1 Tree Survey

Option 2 Aerial Estimation

20-Year Canopy Calculation

•    Measure average canopy radius (r) for each tree to be retained

•    Calculate existing canopy area using the formula: Canopy Area (CA)=πr2

•    Total the sum of tree canopy areas and divide by gross site area to obtain canopy coverage percentage

•    Obtain aerial imagery of site

•    Measure site boundaries

•    Measure canopies of individual trees or stand area using leading edges as the forest boundary

•    Divide total canopy measurement by the gross site area to obtain canopy coverage percentage

For each proposed species:

•    Calculate radius (r) of canopy at 20 years maturity

•    Calculate canopy coverage using the formula: CA=πr2

•    Multiply by the proposed quantity to be planted to obtain total species canopy area

•    Total the sum of species canopy area for all proposed species and divide by gross site area to obtain 20-year canopy coverage percentage

(5) To assist in the preservation and retention of significant trees and existing tree canopy outside of critical area protection areas and required buffers and perimeter landscaping, the applicant may utilize the following credits:

(a) Individual significant trees retained on site shall be counted at 125 percent of their actual canopy area.

(b) For clusters or stands of five or more trees, each tree shall be counted at 150 percent of its actual canopy area.

(c) For clusters or stands of five or more significant trees, each tree shall be counted at 200 percent of its actual canopy area.

(d) Retained trees located within no more than 20 feet of a rain garden or a bio-swale on site shall be counted at 150 percent of their actual canopy area.

(e) Retained significant trees qualified to receive flow control credits under Appendix III-C of the Snohomish County Drainage Manual shall be counted at 150 percent of their actual canopy area.

(f) The on-site recreation space required by SCC 30.23A.080 may be reduced by 100 percent if 40 percent or more of the site has existing tree canopy that is retained along with all native vegetation under that canopy area.

(g) A project may be exempted from all other requirements of SCC 30.25.015 and this section if the canopy area of significant trees retained onsite is 45 percent or more of the gross site area and the majority of the canopy is provided by evergreen species.

(h) The minimum required lot area in subdivisions or short subdivisions not using the lot size averaging provisions of SCC 30.23.210 may be reduced by 20 percent when at least 20 percent of the site, not including any critical area protection areas and perimeter buffers, is put into a separate tract or tracts that have at least 20 significant trees per acre and where at least 60 percent of the significant trees within the tract or tracts are retained. This does not change the tree canopy requirements.

(i) For subdivisions or short subdivisions using the lot size averaging provisions of SCC 30.23.210(5), the minimum size for each single lot in SCC 30.23.210(5)(a) may be reduced by 20 percent when at least 20 percent of the site, not including any critical area protection areas and perimeter buffers, is put into a separate tract or tracts that have at least 20 significant trees per acre and where at least 60 percent of the significant trees within the tract or tracts are retained. This does not change the tree canopy requirements.

(6) In addition to the requirements of SCC 30.25.015(5) through (7), trees planted to meet tree canopy requirements in SCC Table 30.25.016(3) shall meet the following criteria:

(a) Sites must be planted or replanted with a minimum of 50 percent evergreen species, except:

(i) The evergreen portion of the required planting mix may be reduced to 37.5 percent when the deciduous mix contains exclusively indigenous species to the Puget Sound region, not including Alder; and

(ii) Sites obtaining tree canopy requirements solely through street trees are exempt from the requirement to include evergreen species in the planting mix;

(b) Sites requiring planting or replanting of tree canopy must plant no more than 30 percent of trees from the same species and no more than 60 percent of trees from the same taxonomic family.

(c) Replacement trees shall be planted in locations appropriate to the species’ growth habit and horticultural requirements;

(d) When preparing the landscaping plan, applicants are encouraged to meet the requirements of SCC Table 30.25.016(3) by conserving existing tree canopy including significant trees and other vegetation located on the site and place new plantings in protected areas (such as street trees, perimeter landscaping, open spaces and critical area protection areas and required buffers) at healthy spacing densities before placing trees within individual lots or yards; and

(e) Replacement trees shall be located in such a manner to minimize damage to trees or structures on the project site and on properties adjoining the project site.

(7) The following tree protection measures shall be taken during clearing or construction:

(a) Tree protective fencing shall be installed along the outer edge of the drip line surrounding the trees retained in order to protect the trees during any land disturbance activities, and fencing shall not be moved to facilitate grading or other construction activity within the protected area;

(b) Tree protective fencing shall be a minimum height of three feet, visible and of durable construction; orange polyethylene laminar fencing is acceptable; and

(c) Signs must be posted on the fence reading "Tree Protection Area."

(8) An applicant may reduce the tree canopy requirements of SCC Table 30.25.016(3) by no more than five percent through a landscape modification when all of the following criteria and those in SCC 30.25.040 are met:

(a) The applicant demonstrates in writing that they have made a good faith effort to comply with the tree canopy requirements within the physical constraints of the site by:

(i) Retaining as much of the tree canopy as possible on site consistent with best management practices for maintaining the health of trees; or

(ii) Replanting as much of the tree canopy as possible on site consistent with best management practices for maintaining the health of trees;

(b)  The applicant proposes to plant additional understory vegetation or ground cover area, excluding lawn cover, invasive species or noxious weeds, to fulfill the remaining canopy requirement in SCC Table 30.25.016(3) not met by retention or replanting of tree canopy; and

(c) When critical areas protection area buffers exist on site and those buffers are not highly functioning, the applicant proposes to enhance the buffers by removing invasive species and noxious weeds and/or planting vegetation indigenous to the Pacific Northwest, spaced for maximum survivability.

(9) On sites without any existing tree canopy, the director may reduce the requirements of SCC Table 30.26.016(3) by no more than five percentage points (for example, 30 percent requirement can be reduced to 25 percent) when an applicant provides a 25 percent increase in the area of open space than that required under SCC Table 30.23A.080(2). The following shall not be eligible for this reduction:

(a) Short subdivisions less than seven lots;

(b) Single family detached units, cottage housing, townhouse, multi-family less than 10 units; and

(c) Urban center development.

(10) The county engineer may modify required frontage improvements to retain significant trees as street trees.

(11) Retained significant trees, trees planted as replacements for significant trees, and trees planted to meet requirements in subsection (3) of this section may not be removed except when determined in writing by a certified arborist to constitute a hazard. Any replacement or significant trees removed without proper documentation from a certified arborist shall be subject to a fine as determined under chapter 30.85 SCC.

(12) Any significant trees identified in a landscape plan to be retained and subsequently damaged or removed during site development shall be replaced at a rate of three trees for each one damaged or removed significant tree. Failure to replace damaged or removed significant trees shall be subject to a fine as determined under chapter 30.85 SCC.

To protect and enhance rural character, landscaping for rural cluster subdivision development under chapter 30.41C SCC shall provide screening to minimize the visibility of rural cluster subdivisions from adjoining roadways and from adjacent residential property. While 100 percent screening is not necessary, the view of new development should be softened and minimized to the greatest extent possible.

(1) Retention of 50 percent of the overall tree canopy on the pre-development site is recommended to minimize change to the visual character of the site.

(2) Visual screening shall be provided through retention of native vegetation, new landscape planting, or a combination of the two, in the following locations:

(a) In the required setback buffer from the road rights-of-way;

(b) In the perimeter buffer of the site where it abuts adjacent residential property; and

(c) In the open space buffers between clusters.

(3) When retention of existing vegetation is not adequate to screen development from road rights-of-way or from adjacent residential property, landscape installation shall be required for additional visual screening. Landscape installation shall be in clustered plantings pursuant to SCC 30.25.033(4) that are each approximately 40 feet long, aligned parallel to the development boundary lines and extending the length of the property line, and 25 feet in depth measured perpendicular to the development property line. Planting clusters shall be alternated in parallel rows as illustrated in Figure 30.25.033 (3), to achieve an informal appearance.

(4) Placement requirements may be redistributed or reduced by 20 percent when the landscape plan defines the local variations in topography, views, and character-defining elements, both natural and manmade, and accordingly sites a variety of landscape groupings to provide visual buffers at strategic points to diminish the visual impact of the housing clusters on the public traveling along adjoining roads and on houses located on adjacent properties. The modified planting plan also shall preserve landscape features and viewsheds for the visual benefit of the public and adjacent properties whenever possible.

(5) Rural cluster subdivision landscaping shall meet the following standards:

(a) Plant combinations of trees and shrubs located in planted clusters that:

(i) Preserve existing vegetation wherever feasible;

(ii) Use native plants for new planting installations or a mix of native plants and 20 to 30 percent non-native plants if they are naturalized vegetation typical of established rural uses, such as orchards, hedgerows or windbreaks; and

(iii) Incorporate both evergreen and deciduous species of trees and shrubs that are in varying degrees of maturity at planting and can establish a natural succession of growth.

(b) For standard landscape groupings:

(i) Trees and shrubs must be two-thirds evergreen species;

(ii) Each plant grouping shall contain trees planted approximately 15' on center in a triangular or offset pattern;

(iii) Evergreen and deciduous shrubs shall be located at no greater than 8 feet on center;

(iv) Evergreen trees shall have a minimum height of 8 feet at the time of planting; and

(d) Preference shall be given to Snohomish County-grown tree and vegetation stock, to help promote a viable agricultural industry and opportunity in the county.

(6) Existing trees shall be retained in the setback, perimeter and cluster separation buffers where wind-throw loss can be minimized, as determined by a qualified landscape designer. When enhancement is necessary using the provisions of subsections (2), (3), (4) and (5) of this section to prevent significant wind-throw loss or to support a remnant forest environment, the extent of the enhancement shall be determined by a qualified landscape designer using the screening provisions of this section. The tree retention requirements of this provision do not apply to any forest practice occurring on forest land as those terms are defined by RCW 76.09.020 of the Forest Practices Act, chapter 76.09 RCW.

(7) Non-native vegetation that has become part of the rural landscape and character such as orchards, hedgerows and windbreaks shall be retained.

(8) Landscaping of stormwater detention facilities is required in accordance with SCC 30.25.023.
