    Give Your Input on Water Supply and Wastewater Regulations - Hearings Continued

    ***Hearings have been continued.

    The public is invited to review and comment on proposed revisions to the Zoning Resolution and Land Development Regulation related to water supply and wastewater regulations. The water supply and wastewater regulations are being revised to provide clear requirements for the development community and citizens as well as providing an effective method for evaluating water availability.

    There are two ways to get involved. The first is to attend the public hearings. The Planning Commission will review and make recommendations to the Board of County Commissioners, which makes the final decision on the proposed changes.

    Planning Commission: Wednesday, February 27, 2013 at 6:15 p.m. - continued to April 3
    Board of County Commissioners: Tuesday, March 19, 2013 at 8 a.m. - continued to April 30

    Both hearings are held in Hearing Room 1 of the Jefferson County Administration and Courts Building, 100 Jefferson County Parkway. Public testimony is welcomed.

    The second way is to review the draft changes online. It can also be navigated to by going to the main Planning & Zoning page, www.jeffco.us/planning, and then following the link in the “revised regulations” announcement to one of the below sections:

    • Zoning Resolution - Section 1 - Administrative Provisions
    • Zoning Resolution - Section 54 - Mountain Ground Water Overlay District
    • Land Development Regulation - Section 4 - Submittal Requirements
    • Land Development Regulation - Section 21 - Water Supply
    • Land Development Regulation - Section 22 – Wastewater

    Please email comments to Patrick O’Connell (poconnel@jeffco.us) or Roy Laws (rlaws@jeffco.us).

    The four major components of the regulation revisions include:

    Legal proof of water
    The legal proof of water would not be required for rezoning or special use applications. Legal proof of water would be required for plat and site development plan applications.

    Physical availability of water (two methods)
    The primary method will be the Water Availability Analysis (WAA) which will be completed by staff. The WAA is based on a GIS model evaluating a simplified water budget on a sub-basin level. The WAA will have consistent hydrogeologic parameters involved in each analysis in order to provide more uniform water resource data across the county. County staff met with staff from the USGS and Division of Water Resources in the development of the WAA. The WAA will take into account the basin area, estimated annual precipitation, estimated recharge from precipitation, water withdrawals based on the number & type of permitted wells in the basin, estimated recharge from waste water return flows (ISDS, galleries, etc), and water requirements associated with the proposed uses.

    The other method to supplement the WAA will be an Aquifer Test (completed in accordance with the existing requirements) which would be required at the time of rezoning or plat/SDP application if the water requirement for the project exceeds 0.28 or 0.10 acre feet per acre per year, respectively.

    Water Quality
    The Standard Chemical Analysis list has been updated and includes a slight reduction in testing requirements. The water quality analysis would be required with plat and SDP applications. A note will also be added to the record document if there are any exceedances of the Colorado Primary Drinking Water Regulations.

    The wastewater section was updated to provide additional clarification regarding the different types of wastewater systems and to update the terminology to industry standards.
