16.60.010 Purpose

Whereas growth, the spread of development, and increasing demands upon natural resources have the effect of encroaching upon, impacting or eliminating many of the intact native soils and vegetation, trees and natural resources and processes associated therewith which, if preserved and maintained in an undisturbed and natural condition, provide important physical, aesthetic, recreation and economic assets to existing and future residents of the city; and whereas the city council finds (1) that trees, healthy soils, and native vegetation protect public health through the capturing and filtering of stormwater runoff, absorption of air pollutants and contamination, through the reduction of excessive noise and mental and physical damage related to noise pollution, through their cooling effect in the summer months and insulating effects in winter, through their positive impact on global climate change; (2) that trees, healthy soils, and native vegetation provide for public safety through the prevention of soil erosion, siltation and flooding; (3) that trees, healthy soils, and native vegetation are essential to the general welfare of the city by maintaining the natural beauty and the irreplaceable heritage for existing and future city residents; and (4) that Olympia can promote urban forestry and land management practices which will preserve or enhance trees, healthy soils, and native vegetation on public and private lands as they transition from natural areas into an urban environment. Therefore, the purposes of this chapter are:

A.    To provide for the protection, preservation, replacement, proper maintenance and use of trees, soils, and native vegetation located in this city in order to preserve and enhance the city’s physical and aesthetic character by preventing untimely and indiscriminate removal or destruction of trees, healthy soils, and native vegetation;

B.    To protect trees, healthy soils, and native vegetation in the city for their economic support of local property values and to preserve and enhance this region’s natural beauty;

C.    To minimize the adverse impacts of land disturbing activities on stormwater infiltration, soil erosion, air quality, sedimentation and pollution of natural waterways, in order to minimize the public and private costs for stormwater control and treatment, utility maintenance and removal of pollution from our natural waterways;

D.    To promote site planning, construction practices and horticultural practices that are consistent with the reasonable use of property;

E.    To provide for the paramount public concern for these natural resources in the interest of a healthier and safer place in which to live and to promote the general welfare of the residents of this city;

F.    To implement the goals and objectives of the Washington State Environmental Policy Act; and

G.    To implement the goals and objectives of the City’s Comprehensive Plan.

16.60.080 Tree density requirement

A.    Minimum Tree Density Requirement Established. A minimum tree density of 30 tree units per acre is required on the buildable area of each site, except within the Green Cove Basin (see OMC 16.60.080(5) and in critical areas, see OMC 18.32. The tree density may consist of existing trees, replacement trees or a combination of existing and replacement trees, pursuant to the priority established in Section 16.60.070. For the purpose of calculating required minimum tree density in areas outside of Green Cove, critical areas, critical area buffers, city rights-of-way, and areas to be dedicated as city rights-of-way are excluded from the buildable area of the site. For areas within Green Cove, only city rights-of-way and areas dedicated as rights-of-way are excluded from the buildable area of the site.

B.    Tree Density Calculation. Specific Tree Density calculations and replacement tree standards are delineated in the City of Olympia’s Urban Forestry Manual. Table 16.60.080 A shows the required minimum tree density and replacement tree requirements for various activities.

1.    Developing properties are required to meet a minimum tree density of 30 tree units per acre.
