Re: Determination of Zoned Land Exemption to Boulder County’s Land

Use Code, Article 8 - Location and Extent, Areas and Activities of

State Interest for Denver Water’s Moffat Collection System Project

Dear Mr. Case,

Pursuant to Section 8-406(A) of the Boulder County Land Use Code (“LUC”),

Denver Water seeks your confirmation that the expansion of Gross Reservoir, also known

as the Moffat Collection System Project (“Project”), is exempt from Article 8 of the LUC

per the “zoned land exemption.” Under Article 8, Boulder County regulates “Areas and

Activities of State Interest” pursuant to C.R.S. 24-65.1-101, et seq. (“H.B. 1041” or

“1041 permit”).

Denver Water anticipates deadlines within a Federal Energy Regulatory

Commission (“FERC”) Order for various construction-related plans and activities

requiring FERC approval prior to construction of the dam. Denver Water is beginning

preliminary work in anticipation of strict construction timelines and deadlines. These

plans sometimes require, and will greatly benefit from, Boulder County’s engagement

and input now and in the near term. For instance, Colorado Department of

Transportation (“CDOT”) is interested in having Denver Water improve the intersection

of Boulder County’s Gross Dam Road and State Highway 72. Also, in the near term,

Denver Water will host workshops with consulting parties identified in FERC’s Order

(which will include Boulder County and the local community) to develop plans to

minimize construction disturbance within Boulder County and to the local community.

These plans will establish best and preferred methods for traffic management, road use

and maintenance, hours of use, and quarry operation times, among other Project criteria.

Clearly, these matters of local interest will be developed best with Boulder County’s

participation to inform and advise all participants of applicable Boulder County policies,

standards, and criteria. However, Denver Water’s ability to move forward with Boulder

County on plans to improve traffic safety before construction begins has been halted

because Boulder County has declined to engage without Denver Water’s submission of a

1041 permit application. Based on our research, the Project falls within the zoned land

exemption in H.B. 1041 for the reasons discussed herein.

In general, H.B. 1041 entitles local governments to designate areas and activities

of state interest and regulate those areas through their respective zoning codes. Colo.

2

Rev. Stat. §24-65.1-101. At the same time, the law exempts from the 1041 process “any

development or activity . . . on land which has been zoned by the appropriate local

government for the use contemplated by such development or activity” as of May 17,

1974. C.R.S.§24-65.1-107(1)(c)(II). See also Droste v. Board of County Commissioners

of County of Pitkin, 85 P.3d 585, 589 (Colo. App. 2003) (holding “the plain language of

the zoned land exemption specifically provides that AASIA [(Areas and Activities of

State Interest Act)] does not apply to ‘any development in an area of state interest’ that

meets the statutory criteria for the exemption.”); “A History of the Colorado Land Use

Commission’s Intervention, 24 Colo. Law. 303 at *303 and FN 14 (February 1995)

(discussing that the development of a Safeway market blocking the view from the historic

Stanley Hotel was not subject to the 1041 requirements because “the area where the

construction took place was actually exempt from state regulation” under C.R.S. Section

24-65.1-107(1)(C)(II) as the land had been zoned in 1967 for commercial development).

Gross Dam and Reservoir was constructed in the 1950s and is located within the

Forestry zoning district and the 100-year floodplain, which means it is also within the

Flood Regulatory Area zoning. The property at issue will continue to be used for a dam

and reservoir, although larger in size than the current structure. In fact, the size of the

dam following construction fulfills the contemplated use at the time of original design

and construction. Denver Water includes with this letter a survey from February 1946

that is on file with Boulder County (Plat Book G, pages 77-78) showing the dam at the

height contemplated with the Project (depicting the reservoir at the elevation of 7400

feet). We have also attached a copy of the same map from Denver Water’s records for

ease of viewing.

The Project is exempt under the zoned land exemption because the property was

zoned for such uses by right prior to May 17, 1974. As of May 17, 1974, the Flood

Regulatory Area zoning rules applied to “portions of land subject to inundation by the

100-year flood.” Section 3.4 of the zoning rules for a “Flood Regulatory Area” provides:

“Permitted uses: the following open uses shall be permitted within the Flood Regulatory

Area to the extent they are not prohibited in a particular area by any underlying zoning

category: … (4) Utility facilities such as dams, power plants, flowage areas, transmission

lines, pipelines, and water monitoring devices.” Amendment to Boulder County Zoning

Resolution, Approved August 11, 1969, Section 18.5, 3.4(4). The use contemplated for

the Project was not prohibited in the underlying Forestry Zoning District. Thus, 1041

“does not regulate or apply to lands that fall under the zoned land exemption.” See

Droste, 85 P.3d at 589.

Our research into the history of the 1969 Flood Regulatory Areas zoning provides

insight into why dams were viewed as desirable features in a floodplain. A book

published by the City of Boulder notes that during the flood in May 1969, “Gross

Reservoir captured the entire runoff generated above the dam averting what would have

been much greater flooding in the South Boulder Creek valley.” See SILVIA PETTEM,

3

BOULDER’S FLOODS AND FLOOD MANAGEMENT: PAST AND PRESENT 81-

82 (2016). Only a few months later, Boulder County enacted the Flood Area zoning

regulations. Although flood control is not the purpose of Gross Dam, it provides a flood

protection benefit to Boulder County, as demonstrated in 1969 and more recently in

2013.

We seek Boulder County’s concurrence that the Project is exempt from Article 8

of the LUC, so we can begin preparatory work and specific construction activity plans

that are being developed now and in the very near term with Boulder County’s

engagement. We also look forward to working with Boulder County to secure any

ancillary permits necessary for successful completion of the Project. Though the Project

is exempt from 1041, Denver Water is open to alternative ideas and processes to engage

the public and Boulder County Commissioners throughout the process.

Sincerely,

Jeff Martin
