13.10.040 Proposals for Latecomers Agreements.
A. A proposal for a Latecomers Agreement shall be submitted to the Director or an authorized designee for consideration by the County at the time of application or prior to plan approval of the sewer facility.
B. A complete proposal for a Latecomers Agreement shall, at a minimum, include:
1. A complete submittal for a sewer line extension (SWLE) permit application including, but not limited to, a proposed Sewer Facility Plan for the Improvements;
2. An Engineer's Estimate of the construction costs for the Improvements;
3. A proposed Tributary Service Area map; and
4. A Conceptual Sewerage Plan for the Tributary Service Area.
C. The Engineer's Estimate shall include an estimate of the Total Eligible Construction Costs as described in PCC 13.10.050. The Engineer's Estimate must be prepared and stamped by a Washington State Registered Professional Engineer.
D. The applicant's proposed Tributary Service Area shall include all properties which may subsequently use or require service from the Improvements, including the Development, and including property that will receive service from sewer lines connected to the Improvements. Only those properties within a defined sewer sub-basin whose wastewater could flow to the Improvements in a manner in keeping with the County's USP, the Capital Facilities Plan, any approved Sewer Facility Plan, and Pierce County Sewer Standards shall be included in the Tributary Service Area. The feasibility of a property to receive service from the Improvements does not in and of itself prescribe inclusion in the Tributary Service Area. The size and limits of the Tributary Service Area must be reviewed and approved by the Department prior to Sewer Facility Plan approval. The Tributary Service Area map must be prepared and stamped by a Washington State Registered Professional Engineer.
E. The applicant's Conceptual Sewerage Plan shall include the proposed design to serve all of the proposed lots within the Development as well as a conceptual design to serve the rest of the Tributary Service Area. At a minimum, the Conceptual Sewerage Plan must include the proposed sewer alignment, manhole locations, rim and invert elevations, pipe diameter, pipe slope, flow calculations for design capacity and flow velocities, topography, and parcel numbers and current zoning of all the properties within the Tributary Service Area. Approval of the applicant's Conceptual Sewerage Plan for the purpose of determining the eligibility of the Improvements for reimbursement shall not be construed to be an approval of all the design elements associated with said sewerage plan as they pertain to permanent sewer service for the Tributary Service Area. The Conceptual Sewerage Plan must be prepared and stamped by a Washington State Registered Professional Engineer.
F. The County may require additional plans, specifications, easements, and legal documents as deemed necessary by the Department to evaluate and administer the Latecomers Agreement.
G. The applicant may request the County participate in financing sewer facilities projects by providing connection charge credits to the applicant as set forth in PCC 13.10.065. The County has discretion to grant or deny the request and to set the terms for any County participation.
