Executive Summary:
This item seeks to reimburse the housing developer, Siesta Senior Apartments L.P. (Siesta Senior Apartments), for the costs associated with replacing 880 linear feet of sanitary sewer pipeline required by Sonoma Valley County Sanitation District (District) to accommodate the additional residents of Siesta Senior Apartments’ proposed affordable senior housing project. The District will apply the construction costs incurred by Siesta Senior Apartments toward the required capacity charge and is requesting that the Board approve reimbursement of these costs in excess of the capacity charge offset of $119,335.
Discussion:
Siesta Senior Apartments L.P. is the developer of the proposed Siesta Affordable Senior Housing Project (Housing Project) on Siesta Way in Boyes Hot Springs, California. Milestone Construction Group, LLC is Siesta Senior Apartments L.P.’s construction contractor.
On March 18, 2021, the District sent a letter to Adobe Associates, Inc., the civil engineering firm designing Housing Project, informing them that a hydraulic capacity analysis of the sewage collection system downstream from the Housing Project indicated a need for mitigation measures so that the proposed Housing Project would not increase the risk of sanitary sewer overflows (SSO).
The District determined that while any mitigation measures preventing an increased risk of SSOs could be acceptable, the most appropriate mitigation would be to replace 880 feet of sanitary sewer pipe in Fairview Lane from manhole M103-26 to manhole M104-1 (Sewer Project). The Sewer Project provides capacity for both the additional contributory flows from the Housing Project and the existing sewer flows that occur during wet weather events. The District indicated that it would credit the costs incurred for design and construction against the Housing Project’s sewer capacity charge (“connection fee” as stated in Article V of the District Sanitation Code and in Section VII of the District Ordinance No. 102).
The parties agree that the overall Sewer Project costs for the purposes of the agreement is $1,208,513. This amount exceeds the Housing Project’s sewer capacity charge (calculated retroactively to 2022 capacity charge rates) by $119,335. Siesta Senior Apartments elected to begin construction of the Sewer Project in advance of the agreement.
Siesta Senior Apartments initiated construction of the project in June 2023, knowing that the requested reimbursement ($119,335) beyond the sewer capacity charge would be subject to Board approval. The construction of the project was completed in September 2023.
Under the agreement, Siesta Senior Apartments’ capacity charges will be credited and Milestone will be reimbursed for costs totalling $119,335 incurred for replacement of 880 feet of sanitary sewer pipe on Fairview Lane. The reimbursement cost is $119,335; the term end date is June 30, 2024.
