Kum & Go 300 Subdivision 1 Thornton, CO Olsson Project #013-1721

I. GENERAL LOCATION AND DESCRIPTION

This Final Utility Study has been prepared for Kum & Go 300 Subdivision (the PROJECT) by Olsson Associates. This study evaluates the PROJECT’s planned water & sanitary sewer extensions & connections to the City’s system in order to assess impacts to the City’s existing utility infrastructure.

A. Location

The PROJECT encompasses the development of Lots 1-3, Kum & Go Subdivision 300 located within the Southeast 1/4 of Section 21, Township 2 South, Range 68 West of the Sixth Principal Meridian, City of Thornton, County of Adams, State of Colorado. Refer to Figure 1 for project location. The PROJECT is situated at the northeast quadrant of the intersection between W. 88th Avenue and Pecos Street. W. 88th Avenue has a ROW width of 100 ft, while the Pecos ROW width is approximately 80 ft adjacent to the site.

FINAL UTILITY STUDY

Kum & Go 300 Subdivision 2 Thornton, CO Olsson Project #013-1721

Currently, the majority of the existing property is vacant with a small area dedicated as a donation center drop-off. The site is bordered by a manufactured home park on its north, a condominium/apartment complex on its east, commercial development to the south, and an amusement water park on its west side. The property is zoned community retail and allows for a variety of retail uses including high visibility pad uses with or without drive through orientations, free-standing; multi-tenant retail buildings, anchor and junior anchor buildings.

B. Description of Property The PROJECT consists of 6.354± acres (combined area of Lots 1-3, exclusive of the additional ROW to be dedicated along Pecos Street). A high point exists near the shared property line between Lots 2 & 3, with gentle slopes towards the northeast & south. Native vegetation currently covers the majority of the existing parcel of land. Phase I of the development will include construction of a convenience store & fueling canopy on Lot 1 during the Spring of 2015. Phase II of the development is anticipated to include full build-out of Lots 2 & 3, as depicted on the preliminary utility plans within Appendix A. At the time of this study, the timing of Phase II had not yet been determined. During the construction of Phase I improvements, an 8” sanitary sewer main will be extended from an existing manhole within Osage Street to the north boundary of Lot 1. The convenience store will extend two separate 4” service lines to the new main (one for kitchen waste & one for domestic waste). Upon Phase II development, it is expected that the buildings on Lots 2 & 3 will extend service lines to the main extension installed during Phase I. Refer to the preliminary sanitary sewer plan within Appendix D for proposed Phase I & II improvements. During the construction of Phase I improvements, an 8” water main will be extended from an existing 16” water main within Pecos Street, along the north boundary of Lot 1. The convenience store will extend a 2” service line to a meter placed just south of the new main, and will tap the new main with a 1.5” service. Additionally, the new main will include a tap for a fire hydrant lateral & assembly due south of the north boundary of Lot 1. A fire hydrant lateral will also be tied-into an existing 8” main within 88th Avenue, and a hydrant will be installed within the north side of the 88th Avenue ROW, due south of the convenience store. Upon Phase II development, the new 8” main will be extended along the south & east sides of Lot 3, and will tie-into an existing 8” main within the adjacent multifamily project. It is expected that the buildings on Lots 2 & 3 will extend service lines to the main extension installed during Phase II. Refer to the preliminary water plan within Appendix D for proposed Phase I & II improvements.

II. BASINS AND PRESSURE ZONES

A. Major Basin Description

Per the City’s 2010 Water and Wastewater Systems Master Plan (the MASTER STUDY), the PROJECT is located within Sewer Basin A and Pressure Zone 4. Conversations with City staff indicated that utility reports for adjacent subdivisions are non-existent.

Page 6: 131721 Final Utility Study KG 300 - City of Thornton the same said Sections within the MANUAL. WaterCAD and SewerCAD software was used to model the proposed utility improvements for

FINAL UTILITY STUDY

Kum & Go 300 Subdivision 3 Thornton, CO Olsson Project #013-1721

According to the MASTER STUDY’s future land use map, the PROJECT is located in an area of anticipated commercial development. Furthermore, no immediate improvements are recommended or anticipated for Basin A or Pressure Zone 4.

III. DESIGN CRITERIA

A. Regulations The design of utility extensions and the subsequent information contained within this study were prepared in accordance with criteria set forth in the City of Thornton’s Standards & Specifications for the Design & Construction of Public & Private Improvements, October 2012 (the MANUAL). At this time, requested deviations from the MANUAL’s criteria are, neither, necessary nor sought.

B. Development Criteria Reference and Constraints

According to the MASTER STUDY, the highest elevation and associated lowest observed pressure within Zone 4 are 5526 ft and 40 psi, respectively. Additionally, the lowest elevation and associated highest observed pressure within Zone 4 are 5370 ft and 117 psi, respectively. Zone 4 reservoir’s low hydraulic grade line is 5602 ft, while the same reservoir’s high hydraulic grade line is 5640 ft. Since the MASTER STUDY identifies future commercial development within the PROJECT area, and did not identify any immediate required improvements to either Zone 4 or Basin A (besides addressing water quality and tank tracking within Zone 4), development of the PROJECT as depicted on the plans located in Appendix D is not anticipated to adversely affect the City’s existing utility infrastructure.

C. System Design Criteria Water and sewer improvements for the PROJECT were designed according to Sections 200 & 300 within the MANUAL. Water demand and sewer flow estimates were also obtained from the same said Sections within the MANUAL. WaterCAD and SewerCAD software was used to model the proposed utility improvements for the PROJECT. Modeling output indicates that the proposed improvements meet the City’s water distribution system design criteria set forth in Section 203.2 of the MANUAL, except for 203.2.B.1. Because the PROJECT is situated (vertically) near the lower threshold of Zone 4 elevations, we expected to see higher static system pressures. When no demands are placed on the proposed system, static pressures are in excess of 100 psi. To that end, we do not anticipate any modifications to the existing infrastructure, but recognize the need for PRVs within the PROJECT’s planned buildings. Furthermore, modeling output indicates that the proposed improvements meet the City’s sanitary sewer design criteria set forth in Section 303.2 of the MANUAL. Refer to Appendix A for water demand & sewer flow calculations, and Appendices B & C for water model and sewer model output.

IV. CONCLUSIONS

A. Compliance with Standards

It is anticipated that construction of Phase I & II improvements described in this study will not adversely impact the City’s existing infrastructure. The PROJECT’s buildings will not create an inordinate demand on the City’s water system, nor will it add significant waste to the City’s sanitary sewer system.
