Discussion and possible action on any and all matters regarding Subdivision Case No. 2016-0423 P&F. A request by Edais Engineering, Inc., on behalf of Riedel Holdings, LLC, property owner, for the final approval for Las Quintas de San Luis II Subdivision located south of County 22nd Street between the East Main Canal and Las Quintas Subdivision. (John Starkey, Planning and Zoning Director)

This subdivision will contain approximately 27.58 acres and is proposed to be divided into 113 lots, ranging in size from approximately 6,000 to 16,833.33 square feet. The property is located south of County 22nd Street between the East Main Canal and Las Quintas Subdivision. Assessor's Parcel No. 776-11-001 and 776-03-003, San Luis, Arizona. This property has a general plan land use designation of Neighborhood. 

The area is zoned Medium Density Residential (R1-6) and is currently undeveloped. The areas to the west, north and south are zoned as Rural Area Residential (RA-10) and are undeveloped land and only the property to the west is being used for agricultural purposes. The area to the east is zoned as Medium-High Density Residential (R-2) and is developed as single family homes (Las Quintas de San Luis and Bienestar Estates No. 7A Subdivisions). 

GENERAL PLAN:
This area is designated as Neighborhood in the City of San Luis 2020 General Plan. The activities proposed will be consistent with that designation (Chapter 2, Page 19-20). The Neighborhood Land Use designation allows all types of residential development.

                           City makes a formal request for access for the wastewater line from the Superintendent of the High School District.
January 4th, this item was presented to Council on their work session meeting. Staff presented the main concerns and the options regarding the slope maintenance and the sewer connection.
January 5th. City staff delivers on a letter of understanding for a right of way for the preferred route for a gravity line for the wastewater line. On the same day, the Superintendent of the High School District calls that the School is willing to take the City's request for permission for access for a wastewater line to the School Board on February 8th with certain very reasonable conditions to be worked out with the City.

Most of the engineering issues have been addressed.  The main concerns the staff has been working on were the disclosure and maintenance of slopes and the sewer connection for the subdivision.

The maintenance of slopes will be responsibility of each individual property owner.  Staff is recommending the attached conditions for approval of the plat.  Staff is recommending the attached CC&R’s which follow the conditions and include other restrictions the Developer wanted. Both the City and the Developer want to make sure that the property owners and future owners are aware that it’s their responsibility to control the erosion as designed.

The other main concern is the sewer connection for the subdivision.  When the San Luis High School sewage lift station was designed, its intent was to serve the surrounding properties including the proposed subdivision.  As demonstrated by the gravity sewer plans already prepared by Edais Engineering, a gravity sewer line will physically work. The intent for the gravity sewer pipe installed across the East Main Canal at County 22nd Street, when the canal crossing was constructed, was to run a gravity sewer line at the correct slopes from Las Quintas II to San Luis High School lift station.

In order to follow the sewer service area plan and construct a sewer gravity line, the developer must obtain land from a private owner between County 22nd and the San Luis High School lift station. After the Work Session on January 4, the owner of said land, according to his engineer, will grant the easement or right of way to the City for the construction of the sewer line at no cost to City or the developer. In exchange for the conveyance of the right of way the land owner will not participate in a payback agreement. All parties have agreed on those terms and the developer would like to move forward with this option.

At the time of the writing of this agenda item, staff had not yet received the final plat.  Staff will have a recommendation at the time the item is called.
