The purpose of these standards is to provide standards for the design and maintenance of parkways in the city. Parkways are important to individual property owners and the city as a whole for reason that include, but are not limited to, the following:
a. 
Parkways provide soil volume that street trees need to grow into healthy, mature trees that provide shade, collect storm water, consume carbon and provide other environmental and health benefits.
b. 
Parkways can collect and treat storm water and irrigation runoff and return it to the groundwater table.
c. 
Parkways provide a buffer between sidewalks and streets.
d. 
Parkways improve the curb appeal and value of homes.
e. 
Parkways enhance the visual quality of the city.
(Ord. 19-1074 § 7, 2019)
This chapter shall apply to all parkways in the city, as that term is defined in Title 19 of this code. The parkway design standards in Section 11.46.050 shall apply to all newly constructed parkways adjacent to residential properties, parkways for residential properties that are undergoing a major remodel (as that term is defined in Title 19) and parkways for residential properties that are disturbing, improving or changing fifty percent or more the area of the parkway adjacent to the property. Notwithstanding, parkways that are subject to an streetscape master plan adopted by the City Council shall comply with the provisions in the adopted streetscape master plan in lieu of compliance with the design standards in Section 11.46.050.

(Ord. 19-1074 § 7, 2019)
Parkways shall be constructed according to the following requirements:
a. 
No more than twenty-five percent of the parkway area shall contain hardscape paving materials. If the requirements of curbside access paving described in subsections g and h of this section, by themselves cause exceedance of this standard, this standard shall be waived and no further paving allowed.
b. 
No less than fifty percent of the parkway area shall be covered with planting materials. Planting materials shall be selected from those plants listed in the Parkway Design Guide, or materials that are approved by the City Engineer and comply with the following:
1. 
Do not require mowing more frequently than once every few months;
2. 
Are drought tolerant and can survive with irrigation only occasionally from November through March, once a week April through June, and twice a week July through October;
3. 
Do not exceed a height of twenty-four inches at full maturity, as measured from the surface of the parkway;
4. 
Do not have thorns or sharp edges;
5. 
Are not poisonous, noxious, or toxic when ingested or touched by persons of ordinary sensitivity;
6. 
Are not invasive plants or listed as prohibited in the Parkway Design Guide; and
7. 
Do not form a continuous hedge or screen at full maturity.
c. 
Only walkable surfaces and plants shall be installed within twelve inches of a fire hydrant, water meter, utility pole, street light, or similar utility structure or equipment. If the utility owner requires a greater clearance, then that greater setback shall apply. Walkable plantings shall not obscure the visibility of the structures.
d. 
Within the parkway, non-vegetative ground cover materials may be installed above firm, stable soil material and at a thickness of no more than two inches.

f. 
All irrigation systems installed in the parkway shall be designed in a manner that results in no overspray onto the sidewalk, access walks, or street and be consistent with the applicable sections of Chapter 19.26 Landscaping Standards and State's Model Water-Efficient Landscape Ordinance. Irrigation systems shall be buried or installed in a manner that does not create a tripping hazard.
g. 
A convenience strip consisting of a minimum eighteen inch wide path made of hardscape paving material that is the same finished elevation as the curb and sloped two percent towards the curb, and runs parallel to, and along, the back of the curb shall be provided on all parkways that do not provide a minimum eighteen inch walkable surface along the curb.
h. 
All parkways that are not made of walkable surfaces or walkable plants shall also provide an access path consisting of a up to twenty-four inch wide hardscape paving material access path at the same finished elevation as the adjacent curb and sidewalk and sloped two percent toward the curb at the following locations:
