2 Page 2 THORNTON FIRE DEPARTMENT Fire Protection Engineer II (David Lanning, ) 1. The Fire Department Fire Prevention Division has reviewed the Conceptual Site Plan in accordance with International Fire Code Section 503 and The submitted site plan depicts a very involved network of drives, which are to serve as fire apparatus access to a number of buildings; however, these plans lack information and detail needed to determine Section 503 compliance. Therefore, the submittal is not approved. 3. Some information, such as fire truck turning templates and all required dimensions for the various elements of the access system is needed at this time. Other less rigid components such as NO PARKING FIRE LANE signs can be specified in future referrals such as Development Permit and Infrastructure Construction submittals. 4. The following comments pertain to Ware Malcomb Sheet 3 of 10. a. The Utilities depicted on sheet 3 were not reviewed for code compliance. However, comments pertaining to site utilities as shown on Sheet UT1 are noted below. b. Approved fire department access roads shall be provided to all structures. c. At least two points of fire department access is required to each building. d. Fire department access roads shall be extended to within 150 feet of all portions of all structures. i. Except where buildings are equipped with an approved NFPA 13 sprinkler system, fire department access may be extended to within 150 feet of one approved side of the building. e. Fire apparatus access roads shall have an unobstructed width of not less than 20 feet except where aerial apparatus access is required. f. Buildings exceeding 30 feet in height shall be provided with at least one aerial apparatus road 26 feet in width. Aerial apparatus access roads shall be positioned parallel to the longest side of the building and located in accordance with Subsection as amended. g. The required minimum turning radii for apparatus, 25 feet inside and 50 feet outside, shall be demonstrated by submitting turning exhibits which depict apparatus entering/exiting through all points of access and maneuvering throughout site drive aisles to each building.

3 Page 3 h. Print only one maneuver per area per sheet. Do not stack maneuvers. i. Include a note similar to the following on the Development Permit Application Site Plan: i. Fire apparatus access roads shall be permanently signed NO PARKING FIRE LANE in accordance with municipal sign/traffic standards and the following specifications. j. Access roads less than 26 feet wide (32 feet for aerial access roads) shall be marked as fire lanes on both sides of the road. k. Access roads at least 26 feet wide but less than 32 feet wide (32 and 38 feet for aerial access roads) shall have at least one side of the road marked as a fire lane. l. Access roads at least 32 feet (38 feet for aerial access roads) wide need not have fire lane markings. m. The grade of fire access roads shall not exceed seven perecent. The grade of aerial roads shall not exceed five percent. n. Dead-end access roads over 150 feet long require an approved area for turning around the fire apparatus. 5. The following comments pertain to Ware Malcomb Sheet UT1. a. IFC required fire-flow needs to be determined to establish the number and location of fire hydrants. The required fire-flow is based on the total fire flow calculated area (FFCA) including, the total floor area, in square feet, of all floor levels (including basements) within the exterior walls, and under the horizontal projections of the roof of the building (such as entrance canopies and soffits) and the type of construction. i. In order for TFD to verify FFCA, provide: complete dimensioned plans, information regarding number of stories, construction type and fire sprinkler system type (none or NFPA 13). b. Once FFCA is established the required Fire-flow is determined from Table B c. The number, and spacing, of fire hydrants required to provide the fireflow is ascertained from Table C105.1 and footnotes. d. Where new water mains are extended along streets where hydrants are not needed for protection of structures or similar fire problems, fire hydrants shall be provided at spacing not to exceed 1,200 feet to provide for transportation hazards.

Existing fire hydrants on adjacent properties will not be considered available unless appropriate fire apparatus access road is in close proximity and easements are established to prevent obstructions of such roads and hydrants TRAFFIC ENGINEERING Senior Civil Engineer (Marta Benavente, ) POLICY PLANNING Senior Policy Planner (Robert Larsen, ) 1. Policy Planning has reviewed the above-mentioned referral and has the following comments regarding the 2012 Thornton Comprehensive Plan and other long-range planning documents, as they pertain to this application. a. Comprehensive Plan: i. The above noted parcel has a future land use classification of Urban Village on the Future Land Use Map. This classification provides for high intensity mixed-use development in a compact, pedestrian oriented environment. The Urban Village is characterized by retail, office, restaurant, educational, civic, and entertainment uses on the street level, with residential uses on upper floors. Pedestrian activity is of the highest priority ii. The Urban Village concept originally displayed on the Future Land Use Map has been bifurcated by a school site, disconnecting the proposed development site from the balance of the land area north of the school still identified as Urban Village. The necessary interconnectedness of uses, both residential and non-residential in nature, has been lost. In essence, Washington Street has become a remnant parcel, upon which commercial uses are appropriate. b. North Washington Subarea Plan (NWSA): i. Similar in nature to the Urban Village classification noted in the Comprehensive Plan, adopted language in the NWSA plan states that developments proposed within Urban Village designated areas have some community celebration space, strong architectural controls and consistent architectural theming. People should be able to work, live, and be entertained in a pedestrian oriented area. 2. In summation, Policy Planning supports the proposed development, as long as the developer submits a comprehensive plan amendment changing the future land use classification from Urban Village to Commercial. In addition, the developer must ensure that all individual structures located within the resultant
