This authority is invoked to minimize property damage, promote and protect the public health, safety and welfare, minimize water quality degradation by preventing siltation, contamination and erosion of the city’s waterways, protect aquifers, ensure the safety of city streets, roads and rights-of-way, assure compliance with federal and state storm drainage, surface water management, and water quality regulations and legislation, increase educational and recreational opportunities, encourage the preservation of natural drainage systems, and foster other beneficial public uses. (Ord. 18-528 § 2 (Exh. A)).

13.10.020 Creation and authority.

There was created a storm drainage and surface water management utility and corresponding surface water management fund for the city of Edgewood in 1996, as adopted under Ordinance 96-15. Said storm drainage and surface water management utility shall be administered by the mayor or designee.

The city of Edgewood hereby elects to exercise all lawful powers and authority for the construction, acquisition, and condemnation of property rights, maintenance, management, operations and regulation of storm drainage and surface water runoff systems including, without limitation, all lawful powers to fix, alter, regulate, and control the charges and conditions of the use thereof. (Ord. 18-528 § 2 (Exh. A)).

B. “Detention facility” shall mean an above or below ground facility, such as a pond or tank, that temporarily stores stormwater runoff and subsequently releases it at a slower rate than it is collected by the drainage facility system. There is little or no infiltration of stored stormwater.

C. “Duplex” shall mean one two-family dwelling, either wholly or partially located on a parcel or contiguous parcels, consisting of a building containing not more than two complete living units, designated and/or used to house not more than two families living independently of each other and including all necessary household functions of each such family. For stormwater drainage charge purposes, each duplex unit shall be equivalent to 3,406 square feet of impervious area.

D. “Engineer” shall mean a professional civil engineer, currently licensed by the state of Washington, retained by and acting on behalf of the parcel owner.

E. “Gravel” shall mean all graveled surfaces available for use as roads, driveways, or other access ways for vehicular traffic, parking, production, storage, staging, and holding areas.

F. “Highway” shall mean all impervious ways, lanes, roads, streets, boulevards, and/or places in the city open as a matter of right to public vehicular travel both inside and outside the limits of incorporated cities and towns.

G. “Impervious area” shall mean the horizontally projected surface area of all nonvertical “impervious surface.”

H. “Impervious surface” shall mean a nonvegetated surface area that either: (1) prevents or retards the entry of water into the soil mantle as under natural conditions prior to development; or (2) causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. Common impervious surfaces include, but are not limited to, rooftops, walkways, patios, driveways, parking lots or storage areas, concrete or asphalt paving, gravel roads, packed earthen materials, and oiled, macadam or other surfaces that similarly impede the natural infiltration of stormwater. Open, uncovered retention and/or detention facilities shall not be considered as impervious surfaces for the purposes of this chapter.

I. “Infiltration” shall mean the downward movement of water from the surface to the subsoil.

J. “lnterlocal agreement” shall mean that contract between the city and Pierce County (or other entities) pursuant to Chapter 39.34 RCW, which delineates the terms, conditions and relationships of the parties regarding the plan, design, construction, operation, maintenance and funding of storm drainage systems within the incorporated area.

For stormwater drainage charge purposes, each residential unit shall be equivalent to 2,640 square feet of impervious area.

Q. “Retention facility” shall mean an above or below ground facility, such as a pond or tank, that temporarily stores stormwater runoff and subsequently releases it at a slower rate than it is collected by the drainage facility system. With no surface outflow, discharge is through infiltration and evaporation.

R. “Service charge” means the charge levied on parcels within the city as authorized by EMC 13.10.070.

S. “System” shall mean the entire system of storm drainage and surface water runoff facilities owned by the city or over which the city has right of use and responsibility for the movement and control of storm drainage and surface water runoff, including both naturally occurring and manmade facilities.

B. Credit Program. Sites that utilize rainwater harvesting systems, which retain stormwater on site for later nonpotable use, are eligible for a 10 percent credit. To qualify for a service charge credit, the following must be completed before June 1st of the year preceding the year for which the owner is requesting credit:

1. Credit may be applied to all rate classifications listed in subsection (A) of this section, except for the following: vacant/undeveloped, and state, county and federal public highways. Newly developed properties must fully complete the development process in accordance with Chapter 13.05 EMC before applying for a credit.

2. To qualify for a credit, the owner of record shall provide the city the following documentation, each stamped and signed by the owner’s engineer, that all storm drainage systems serving the entire site are fully compliant with the current requirements for stormwater control, both water quantity and water quality, in Chapter 13.05 EMC:

a. Engineering calculations, demonstrating they are properly sized for their intended use and have a capacity of at least 1,500 gallons per structure; and

b. “As constructed plans”; and

c. Maintenance and operations manual for all drainage facilities, including applicable source control BMPs.

3. Only systems determined by the city to meet or exceed current requirements for operations, maintenance and source control for the site will continue to receive a credit. The owner will be notified of any maintenance deficiencies no later than July 1st to allow for corrective action before October 1st. Systems that are not adequately maintained by October 1st will be dropped from the credit program and will need to submit a new application for readmission into the program.

4. Each owner of record shall provide a “hold harmless” statement on a form provided by the city that indemnifies the city from any loss incurred arising from the construction and maintenance and operation of the owner’s drainage facilities for both water quantity and quality runoff from the owner’s property. This statement shall be signed by the owner and will be recorded with the county auditor by the owner of record. The owner of record shall provide the city a copy of the recorded agreement, with the county auditor’s recording number stamped on it, before the application will be deemed completed.

5. Each owner of record must provide documentation that the city has legal access to the property for the purpose of inspecting the storm control system. New developments are required to record a maintenance covenant for this purpose, and a copy of this recorded document will suffice. If no such documentation is available, the owner shall enter into an agreement with the city that allows the city to enter onto the owner’s parcel to inspect the drainage facility and verify all information submitted by the owner and his/her engineer. The agreement form will be provided by the city. This agreement will be recorded with the county auditor by the owner of record. The owner of record shall provide the city a copy of the recorded agreement, with the county auditor’s recording number stamped on it, before the credit application will be deemed completed.

6. Once accepted into the credit program, a system will remain eligible for a credit for a period of five years, even if the requirements in this title change, assuming the system is not modified, continues to function as designed, and is adequately maintained. Credit may be reapplied for following this five-year period if the system is still in proper working order.

C. The annual service charge credit will be calculated by multiplying the annual service charge by the applicable credit percentage when all of the conditions established for a service charge credit have been met.

D. The annual service charge shall be calculated and collected as described in PCC 11.02.050(E), as adopted by Pierce County Ordinance 2016-72s.

E. Parcel characteristics affecting the service charge which are altered after January 1st of any year shall not be the basis for recalculation of the service charge until the next year. (Ord. 18-528 § 2 (Exh. A)).
