Attached is a brief summary of the project with analysis and map to show the land evaluation process, the presentation material provided to the Planning Commission, and the • Weld County/Longmont/Mead Subarea Analysis—June 2007. (5 it 0( Irk •-4-6 United Power feels that the facts in the materials demonstrate the need and the analysis and due diligence in the site selection to justify the substation at this site. Additionally, with the changes in locating the substation further on the property, an additional 1 acre needs to be added to the original 6.5 acres for drainage only. United would appreciate the consideration of the additional acreage in support of trying to meet the communities' concerns. If there should be any questions or concerns, I can be contacted at 303-637-1209. Thank you in advance for your consideration.

United's Plains Division consists of 800+ acres serving from approximately 136th Avenue on the south to County Line Road on the west to the south end of Johnstown on the north to east of Keenesburg on the east. The past ten years United has been one the fastest growing cooperatives in the United States. The intention of this document is to demonstrate the purpose and need of an electric substation in the immediate area and the steps that have been taken on United's behalf to research the best possible location of this new substation. Purpose/Need An electric substation converts high voltage power from a Transmission Line (generally 115,000 volts and higher) to Distribution voltage (12,470 volts) to serve residents and businesses in an area. Ideally the substation serves approximately a 4 mile radius. Beyond this radius the voltage and reliability starts to drop based on the proximity of the load to the substation. An engineering analysis was completed in 2001, called a Long Range Plan • (LRP), by ESC based in Fort Collins and updated in 2004 that shows a need for a substation in the area between the years of 2006 to 2010 based on load and growth. The load center, in an ideal world the perfect location for the substation, has been calculated to be located at Hwy 66 and WCR 5.5. The load center takes a defined area and the loads and growth in that area and finds the central balance point. In determining the specific need of a substation, besides utilizing the LRP, the utility monitors actual growth, planned growth and developing problems in the area. The growth north of Hwy 119 to WCR 40 has been tremendous over the last six years. The planned growth which includes a new high school, new developments such as The Waterfront, Life Bridge, Kiteley Farms, Mead Town Center, Centex etc along with growing voltage issues in the area has defined a need for a substation. The plan was to build the substation in 2009. However, based on the low voltage power quality issues that developed in 2007, the plan was changed to build a substation in 2008. Current Issues Affecting Power Quality The existing transmission line has been in place for over 32 years. The connection that Tri-State Generation and Transmission has with Platte River Power Authority utilizes an out of date 3-way switch that has been problematic. Today, standards require a more robust design. The plan is to rebuild this at today's standard to provide reliability and safety. The rebuild will need a switching yard of approximately 2 acres. It will be • technically more efficient and have less impact on the area if the two yards are combined. 1 • The existing transmission line from the tie point, County Line and WCR 30, will be rebuilt to a single pole with two circuits to the substation. The transmission line coming out of the substation will still be the single circuit as it exists today. Based on these technical issues, it has been determined the least amount of impact would be to build the substation along the existing transmission line. This would eliminate the need to have two poles with three circuits (2 in and 1 out) if the transmission line was either extended north or south from the existing transmission line. An engineering analysis has been completed for the area projecting out the needs and problems for the area. During the summer of 2007 there were three areas affected with low voltage. The first is north of Mead west of I-25. The next is along I-25 approximately around WCR 40 and the last was between Hwy 66 and Hwy 119 west of I-25. Since the substation can not be completed before the summer of 2008 it was reviewed on what can be done without a substation to remedy the problems. The first two can be solved for one year by adding additional equipment to the existing lines. The issues in these areas currently are low voltage; the third area is not only low voltage but also capacity in the area. Load balancing will be done to free up some capacity but it is uncertain how well this will work. All three of these solutions are only valid for the 2008 peak load. The growth in the area, even with it slower, will exceed the system capabilities. Substation Siting In siting a substation there are several criteria that are reviewed. The criteria are as . follows not in any particular order Proximity to Load Center Location to Transmission Line Agreeable Land Owner Technically Feasible Economics Land Use Aesthetics Attached is a map with the properties reviewed. Below are the results of each of the sites that assisted United in locating the substation on the site selected. All the sites reviewed were based on proximity to the transmission line based on the previous criteria mentioned above. This directly relates to aesthetics and location to transmission line. Site 1: Olander The owner told United that they were not interested in having substation on their property. Site 2: Dorr The owner and real estate representative both told United that they were not interested in subdividing. They would sell the entire parcel though, 55 acres. • 2 Site 3: Silengo • The owner told United that they were not interested in subdividing. They would sell the entire parcel though, 58 acres. Site 4: Centex-Liberty Ranch Already under development. Site 5: Kiteley The owner told United that they have worked hard over the last several years in developing a preliminary plat development and a substation on their property would result in undoing their work. They told United they were not interested. Site 6: Mead Crossings This is a Commercial Subdivision. There were lengthy discussions and initial negotiations. Neither the owner nor his representative wanted a substation located there. The existing platted sites were on the small side associated with usable land. Technically it was not a good location and the economics did not work. The technical issues are based on available land size,proximity to potential flooding (electricity and water do not mix) and the feasibility of getting 8 circuits out of the substation into the area. The cost of the lot was equivalent in cost to Sites 2 and 3 but size being significantly smaller. This site was rejected based on economics, technical issues and non-agreeable seller. Site 7: Waterfront • Offered United a potential site between the reservoir and I-25. Technically this was going to be difficult and has similar constraints as Site 6. C-DOT acquired the property for highway drainage. This eliminated the location. Site 8: Slater The land owner was agreeable to subdivide and sell United the required acreage (6.5 acres plus one (1) additional acre for drainage purposes, totaling 7.5 acres) as long as it was in the northwest corner of her property. The natural land contours is conducive to aesthetically "hiding" the substation and technically this is feasible. The southwest corner of the property is planned to be a new reservoir for the City of Longmont as defined in the Weld County/Longmont/Mead Subarea Analysis, June 2007, for transportation corridors. Site 9: Hergenreder The land owner was only agreeable to subdivide the east part of their property. The west side of the railroad track is more productive as farm land than the east side. The east side is completely contained within the Weld County/Longmont/Mead Subarea Analysis, June 2007. This made the property technically infeasible. Site 10: Longmont Open Space Since this is defined Open Space the requirements to even build in this area are stringent. The first approval needed is by the Open Space Director for the City, which was not • given. Even if it was approved it would then need to go to City Council for a vote and 3 then to the public for a vote. At any time it could be denied. Additionally, City of • Longmont has a Municipal Electric Utility and is not served by United Power. This site is not available. Results After reviewing each of the sites the only site that met the majority of the siting criteria was the Slater property. The process of siting began late in 2004. The analysis has been on going and the preferred site selected mid 2007. There are several items that United Power has done to try to be a"good neighbor". During the notification process we went further than needed such that the residents of Liberty Ranch were notified. Additionally United hosted an Open House to present and discuss the substation to the community. United increased the wall height to 10 feet instead of 8 feet (recommended height by Planning Department) and added brick corner columns. Additionally, United agreed to underground all circuit exits out of the substation, lowered the substation into the natural contours by up to 24 feet, added additional berming on the northwest corner to assist in "protecting" the view from WCR 5.5, agreed to move substation back by approximately another 100 plus feet (requires another 1+acres for drainage for a total of 7.5 acres) and jointly worked with Centex to develop a landscaping plan (plan was not conducive to end means). The • Planning Commission hearing occurred in January of 2008, which resulted in our application being denied on a split vote. A substation is needed in this area not only for reliability but to maintain the economic growth that is occurring not only in Weld County but also Towns of Mead, Firestone and Frederick. With out this facility, any increase in load or new facilities will not be able to be served. • 4 lorikallt 4 •Pili:; aa. •a:.. �.. p uno p@M IrI c CV illisY .'' •i) . �i 1 . 'I Illi ,� .'

Portions of this subarea have been annexed into the City of Longmont and the Town of Mead. Additionally, St. Vrain State Park has been annexed into the Town of Firestone. Two transportation studies have recently been completed in the vicinity of the subarea; the Mead Transportation Plan (Felsburg Holt & Ullevig , August 2006) and the Weld County 1-25 Parallel Arterial Study (Felsburg Holt & Ullevig , September 2003). Although these two studies each address the subarea in part, a need was identified to complete an analysis focusing on the future roadway needs of the subarea, particularly in light of recent modifications to the 1-25 parallel arterial alignment. Weld County, the City of Longmont, and the Town of Mead have jointly commissioned this subarea analysis to identify, in broad terms, the roadway needs of the subarea in order to preserve appropriate rights of way and to highlight areas that may require further detailed study. • Felsburg Holt & Ullevig Page 1 s. � y LD'ya*o �' r. Weld County / Longmont / Mead t `ralke• ,/ r ur- .era.... ��oR�o Subarea Analysis EXISTING AND FUTURE CONDITIONS Study Area The subarea is bounded by SH 119 on the south , County Line Road on the west, SH 66 on the north , and 1-25 on the east. The 12 square mile subarea is currently relatively undeveloped . There are two existing unincorporated residential developments (Meadow Vale and Longview) along SH 119. At the north side of the study area, the Liberty Ranch subdivision in Mead has begun residential sales, and Mead Crossings Business Park in Mead is zoned for commercial uses, although it is largely vacant. There are some industrial uses in the northeast quadrant of the SH 119/County Line Road intersection and some gas/convenience stores located at the I- 25/SH 119 interchange. The St. Vrain State Park is located in the southeastern portion of the study area near the I-25/SH 119 interchange. The remainder of the land is currently agricultural with several homesteads scattered throughout the subarea. Roadway Network 1-25, along the eastern edge of the subarea, serves as the primary north-south highway for travel along Colorado's front range. Although the section of 1-25 through the subarea is currently four lanes, funding has been programmed to widen it to six lanes. Both SH 119 and SH 66 are four lane state highways that provide east-west connections between 1-25 and Longmont. While SH 66 extends to west of the subarea to Lyons, SH 119 extends southwest of the study area to • Boulder. County Line Road , on the western edge of the subarea, provides continuity from SH 7 in Erie up to SH 56 in Berthoud. The section of County Line Road through the study area is currently two lanes, but funding is currently in place to widen portions of it to four lanes. Internal to the subarea, each of the county roads is two lanes; some are paved, but most remain unimproved gravel roads. CR 28 provides the only crossing of 1-25 between SH 119 and SH 66. The CR 28 underpass beneath 1-25 is currently a single lane (originally intended for agricultural- level traffic volumes). The county road system generally follows the mile section-lines; however, the reservoirs and St. Vrain Creek limit the continuity of the county roads. The existing roadway network in the subarea is shown on Figure 1 . Planned Improvements and Potential Issues In order to identify the future needs of the subarea, it is important to first understand the planned improvements and to highlight potential issues associated with the subarea's roadway network. The planned improvements and potential issues are shown on Figure 2 and are described as follows: 1-25 Parallel Arterial: Although the Weld County /-25 Parallel Arterial Study identified the western arterial along the CR 7 alignment, the preferred alignment has subsequently been modified due to changed circumstances. The Mead Transportation Plan identifies the preferred alignment as CR 5 through the Town of Mead to SH 66. Recently, the arterial alignment between SH 66 and SH 119 has been established as CR 5 from SH 66 south to CR 26, then curving west to CR 3 1/2 (this has been recommended by agency staff). This arterial alignment is discontinuous at SH 119, with the arterial continuing along the CR 7 alignment south of SH 119. • Felsburg Holt & Ullevig Page 2 T L CD p L. 0 • �� 1 ., z --,.....r.,-- ® ca •_ 'p li 0) +' i �l1 ff1�, _ �, � _ _ _ . cc ) 'X —�. w �� (--i CR 7 ^ -� CR 7 ,\.__.„--- c I , _ C., -Fa I 7 . \ ) t.______ _ , -0 ," - - 1 ,L i(-- -.-\\_---) _ , ,.....- i _....O,-- 4 N ' 1 CR 51/2 r -- c\i co GrCE CE eat 17 des U U �� `,,1 CR 5 ,,,__ a�to A0 /way cn a� ;i U/e ail . • ('��) CR 3 72 -- r _ . , ., _ _ , _N a ,, , .

In exchange, a new at-grade railroad crossing will be located a half-mile west at Fairview Street. ► 1-25/CR 28: The CR 28 underpass beneath 1-25 is currently a single lane. There are plans to build a new underpass which will accommodate up to four through lanes. Additionally, there are plans to "bow" CR 28 to the south between 1-25 and CR 7 as a part of the Waterfront at Foster Lake development. ► Expansion of Union Reservoir: The City of Longmont has plans to expand Union Reservoir. Since both CR 26 and CR 28 run along the edge of the reservoir, both of these roadway facilities will require realignment in conjunction with the reservoir expansion . The City of Longmont is planning to shift CR 26 slightly to the south around the reservoir and connect it to the existing intersection of County Line Road and 9th Avenue. On the north side of the reservoir, CR 28 will be shifted north . The exact alignment of CR 28 has not yet been determined ; however, it will not align with an existing intersection along County Line Road . ► Liberty Reservoir: The City of Longmont has the rights to create a new reservoir north of CR 28 and east of the Great Western Railway. ► CR 26/CR 7: Both CR 26 and CR 7 terminate at their intersection because St. Vrain • State Park is located to the southeast. The design for the intersection of these facilities is currently under consideration. • Felsburg Holt & Ullevig Page 5 fAead\`` Weld County I Longmont / Mead • 1t)RR ' Subarea Analysis FUTURE TRAVEL DEMAND In order to properly identify the future roadway needs of the subarea, it is important to first understand the nature and volume of future traffic in the subarea. The analysis of future traffic volumes for the subarea is based on the 2030 regional travel demand model developed by the North Front Range Metropolitan Planning Organization (NFR MPO). This computerized model includes the entire North Front Range region . The model area extends from SH 66 on the south to Larimer County Road 88 on the north , and from west of Fort Collins to east of Greeley. As a pad of the Mead Transportation Plan (Felsburg Holt & Ullevig , August 2006), the NFR model was extended south to SH 119. That model has been further refined for use in this subarea analysis. Land Use Forecasts One of the basic inputs to the NFR travel demand model is the future land use. The model uses the future household and employment projections to estimate the number of trips being generated and then assigns those trips to origins and destinations both within and outside the modeling area. The NFR MPO has subdivided its planning area into 815 traffic analysis zones (TAZs). In order to more accurately forecast traffic volumes in the subarea, the 12-square mile subarea has been subdivided into nine TAZs, as shown on Figure 3. Household and employment forecasts in the subarea have been developed for two future • scenarios: 2030 and Post 2030. The 2030 land use forecasts are based on existing developments plus development proposals that have been submitted to Weld County, the City of Longmont, and the Town of Mead. The following development proposals are included in the 2030 land use forecasts: ► West Union Reservoir Liberty Ranch ► Silengo ► Kiteley Ranch ► Mead Crossings Business Park ► Waterfront at Foster Lake ► Adler Estates ► St. Vrain Valley School District High School/Middle School site ► Union (Lifebridge) There are approximately 1 ,800 acres of remaining developable land within the subarea that is not accounted for in the proposed developments listed above. The Post 2030 land use forecasts are based on buildout of this remaining developable land in the subarea. Zoning from Longmont's and Mead's Comprehensive Plans were used to estimate the future development types and densities in these areas. Table 1 shows the 2030 and Post 2030 household and employment forecasts for the nine TAZs in the subarea. • Felsburg Holt & Ullevig Page 6 I 1 ' .

The number of households is projected to nearly double with development of the remaining land, resulting in approximately 12,300 households at buildout of the subarea . In 2030, approximately 5,050 employees are anticipated in the subarea, with an additional 1 ,400 employees at buildout of the subarea. Based on these land use forecasts, the estimated number of daily trips generated by each of the nine zones in 2030 and • Post 2030 is shown on Figure 3. Traffic Forecasts The household and employment forecasts for each TAZ were entered into the NFR travel demand model, and the model was then used to forecast 2030 and Post 2030 traffic volumes. As mentioned , the subarea is not included in the NFR MPO model area, but rather the model has been extended to include this area. Because the subarea is at the edge of the model, the reliability of the traffic forecasts is somewhat limited. For this reason , the traffic forecasts are provided in 5,000 vehicle per day (vpd ) ranges. The resulting 2030 and Post 2030 traffic forecasts are shown on Figure 4. While the Post 2030 forecasts correspond to buildout of the subarea, they do not represent buildout of the surrounding region . • Felsburg Holt & Ullevig Page 8 t r r LO VD • a____14(1d Weld County / Longmont / Mead • rc10R it Subarea Analysis RECOMMENDATIONS Roadway Plan As future development occurs in the subarea, it is important for the county and the municipalities to ensure that appropriate right of way is preserved for the ultimate roadway needs in the subarea. Based , in part, on the travel demand forecasts, a recommended roadway plan has been established , as shown on Figure 5. Internal to the subarea, the CR 5/CR 3 1/2 alignment will serve as a north-south arterial . In the east-west direction , CR 28 will serve as an arterial facility between CR 5 and 1-25, with an underpass beneath 1-25 and connecting east to CR 13. West of CR 5, the realigned CR 26 will serve as an arterial facility with a connection to 9th Avenue, providing continuity through Longmont. On the western edge of the subarea, County Line Road will also serve as an arterial; County Line Road provides continuity from SH 7 in Erie up to SH 56 in Berthoud. Right of way for an ultimate four lane section (plus turn lanes at intersections) should be preserved for all arterial facilities. The remaining county roads in the subarea will serve as collector facilities. In general, the collector facilities should be planned for two through lanes. However, the section of CR 7 from the St. Vrain School District high school and middle school (located approximately half way between CR 26 and CR 28) up to SH 66 may require four lanes in the future to accommodate • school traffic and other traffic generated by the adjacent developments. Right of way for an ultimate four lane section should be preserved along this section of CR 7 . Other Considerations The following is a summary of items that likely require further detailed study in the subarea: ► CR 5/Great Western Railway Crossing: Currently, this railroad crossing is at a severely skewed angle, which limits the visibility and creates difficulty for bicyclists crossing the tracks. In the design of CR 5 in this area, consideration should be given to improving the angle of the railroad crossing. ► CR 5 72 Traffic Calming: The primary north-south arterial through the subarea is accessed via CR 3 % from SH 119, which is a 1 .5 mile offset from the CR 7 arterial south of SH 119 and a 2.5 mile offset from the I-25/SH 119 interchange. Because of this offset, drivers may be tempted to utilize CR 5 1/2 as a cut through route to access either CR 5 or CR 7. Since the desire is to keep CR 5 1/2 as a two lane collector facility, primarily serving the adjacent residential development, consideration should be given to implementing traffic calming measures along this roadway. An access control plan is currently underway for the section of SH 119 between County Line Road and CR 5 1/2. The draft access control plan recommends signalization of the SH 119/CR 5 '/2 intersection if MUTCD warrants are met in the future. If and when a signal is installed at this intersection, the likelihood of cut through traffic using CR 5 1/2 will increase. Possible traffic calming measures to consider along this facility might include speed tables, traffic circles, or chokers (roadway narrowing).

The design for the connection of these two roadways should maintain a collector street standard , allowing for connectivity between the two facilities. • • Felsburg Holt & Ullevig Page 11 I 1 in C• Ss, ccs -- -- CCI � ' DC A i t & = r TA L •_45 cc ) , E-- - . , ---\\,_ _ >) a -,, - -,......„ - ... _ _ , . . , ,_ 4 ' C Ill CR7 _ ,4 O c 0 / el w • , - ,= ' �. �rE'at western._-._ � a \\,....„ Ra1/H,a y Q, (, - �. • � ; U T _ \ ill N 1• ex, . , .
