Preservation of natural vegetation and healthy, existing mature trees (particularly conifers) is preferred if available on the site. Otherwise, street trees and/or landscaping items (including irrigation if appropriate) shall be furnished and installed as may be specifically required by the city. If such is required, landscaping shall be of one of the referenced types as specified in the development guidelines and public works standards or in the Puget Sound Energy document “Energy Landscaping” available at Algona City Hall, and/or as otherwise may be approved by the city. These landscaping items, including trees and irrigation, shall be furnished and installed at the city’s sole discretion, direction, and approval.

All plant material sizes listed shall be the minimum sizes at the time of installation, unless otherwise stated in this section.

Recommended trees for bioretention areas are referenced in Appendix 1 of the Low Impact Development Technical Guidance Manual for Puget Sound. Any landscaping elements meeting the requirements listed herein that are included as part of a low impact development (LID) facility may be counted toward meeting the city landscaping requirements, as approved by the city. It is preferable that trees planted next to a low impact facility such as porous pavements have minimal tree litter. (Ord. 1190-21 § 2, 2021; Ord. 1114-15 § 1; Ord. 965-05 § 9).
