Major Planning Cases

Current Land Development Cases

Arapahoe County's Planning Cases map displays all land development cases actively under review in unincorporated Arapahoe County.  



Land Development Code Update

Arapahoe County is updating its land development code to improve our process and offer alternatives to Planned Unit Development zoning. Please visit our Land Development Code Update page for more information about the project, including the new proposed residential zoning districts and the reorganization of the land development code.

Backyard Bee Keeping and Backyard Chicken Keeping (cases LDC18-005 and LDC18-006)

Arapahoe County recently adopted regulations for backyard bee and chicken keeping in residential-zoned areas with single-family detached housing. The regulations become effective on April 30, 2019. Please visit the Zoning Page for all of the details and supporting documentation.

A-E Agricultural Estate - Reduce Required Lot Width (case LDC19-001)

Arapahoe County recently adopted a reduced lot width requirement for A-E zoned land. Now, the minimum lot width is 600 feet. 

Design Standards for Small Cellular in the Right-of-Way (case E19-024)

Arapahoe County recently updated the Infrastructure Design and Construction Standards manual to include standards for small cellular facilities in the public right-of-way. The update added a new Chapter 14 to the manual, which identifies the process and design requirements for facilities in the right-of-way. These types of wireless facilities tend to be about the size of a small backpack and can be attached to telephone poles, lights, traffic signals, or new poles in the right-of-way. The Board of County Commissioners approved the standards on April 9, 2019.    

Expedition Water Solutions - Saltwater Disposal Facility/Injection Well (case UASI18-001)

Expedition Water Solutions is proposing a saltwater disposal facility to be located on the north side of E Quincy Avenue east of Watkins Road (34501 E Quincy Avenue). The proposed site would include an 8,000 square foot building, a thirty vessel tank battery, a truck unloading area, and a 400' x 400' gravel pad for the proposed injection/disposal well. Saltwater produced from oil and gas operations will be piped or trucked to the facility, where it will be treated and ultimately disposed into the well at a depth of about 10,000 feet. This application will require public hearings at both Planning Commission and the Board of County Commissioners. This page will be updated when those meetings have been scheduled. If you have comments or questions, you may send them to Diane Kocis, who is managing the case.  

Conoco Swan Well Site

The proposed Swan well site is located northwest of the intersection of E 6th Avenue and N Imboden Road, within the future Prosper development. ConocoPhillips is proposing one well and four 500 BBL low-profile tanks, along with other supporting equipment. The Board of County Commissioners approved the application with 16 conditions of approval on August 28, 2018.
ConocoPhillips continues to work toward compliance on the Swan 4-64 6-1 well pad Conditions of Approval adopted by the Board of County Commissioners on August 28, 2018, including: County Engineering Services Division approval of the Northern Emergency Access Road design and inspection and approval of the Southern Emergency Access Road by Bennett-Watkins Fire Rescue.  Drilling cannot proceed until these Conditions of Approval have been met. 

The applicant has submitted an administrative amendment to their approved site, which makes some adjustments to the pad layout and the northern emergency access road. For more information on the proposed amendment you can visit our citizen portal, which includes the applicant's submittal documents. If you have any questions, you may contact Diane Kocis, Arapahoe County Energy Specialist.

Prosper Development

Arapahoe County is currently reviewing a number of cases related to the Prosper development located south of Interstate 70 and N Watkins Road. These cases will eventually have public hearings and we will post the dates as soon as we know them.

The County approved the initial zoning - the Prosper Preliminary Development Plan (PDP) - in early 2015. When fully developed, the Prosper development will cover 5,130 acres (8 square miles) and will include up to 9,000 housing units and 8 million square feet of commercial/office/industrial uses. If you'd like to review the entire Prosper PDP you can download the very large PDP (180 MB) here. You may also download the much smaller Prosper land use plan for an overview of the project.

Initial phases of the Prosper development will rely on Denver Basin aquifer ground water. However, the development will eventually use a combination of renewable surface water, reclaimed wastewater, and lawn irrigation return flow. Per the Prosper water supply plan (70 MB file), when fully developed, 73% of the water in Prosper will be from those renewable sources.

Prosper Water Treatment Plant - The County is currently reviewing a permit for Prosper's initial water treatment plant. This Location & Extent document shows where it's located and what it will look like. The Board of County Commissioners approved the plant on June 27, 2017.

Prosper Preliminary Plat and Final Development Plan - This is the first phase of the project, located east of N Watkins Road. The Final Development Plan includes 977 single-family homes on 754 acres of land. The Final Development Plan includes proposed landscaping and design standards for the potential homes. The preliminary plat shows more detail on the lot layouts. The applicant's letter of intent offers a general overview of the project. The Board of County Commissioners approved both of these items on August 15, 2017.
