Standard Process I. Initial submittal of plans and specifications, and all subsequent correspondence and submittals for public infrastructure improvements including, but net limited to, sanitary sewer and water plains, storm sewer mains, street and transportation improvements, are to be made to the City Engineer's Office, 20 E. Olive Street, P.O. Box 1230, Bozeman, Montana, 59771-12.30. Prior to submission of infrastructure plans and specifications, project approval (preliminary plat, Planned Unit Developments (PUD's), and in some cases Final Site Plans (FSP's)) from the City Commission must be obtained. 2. The minimum number of complete sets of plans and specifications which must be submitted for each review are as follows: Type of Project Number* Reviewers Water and Sewer Main Extensions 4 Sets Eng,, W/S Fire Service Lines 2 Sets Eng,, W/S Streets and/or Storm Sewers 4 Sets Eng., W/S, ST Water & Sewer Mains with Streets 4 Sets Eng,, W/S, ST and/or Stonn Sewers Eng. = Engineering Department * See Paragraph 8 below W/S = Water and Sewer Department ST = Street Department 3. The COB shall attempt to complete the initial review and provide written comments to the Engineer/Owner within thirty (30) calendar days of receiving the initial submittal. A review meeting may be scheduled with the design Engineer and City representatives to discuss review comments if the design Engineer desires. Pre-design and interim meetings with the design Engineer and City Engineering staff are encouraged. 4. To expedite the review process each submittal of revised plans and specifications shall be accompanied by a written response from the Design Engineer which addresses each item 4 in the COB review comment letter. The revised documents will be distributed and reviewed as described above in item 2. Generally, "red-lined" copies of the plans and specifications will be provided to the Design Engineer to facilitate revisions of the documents. Red-lines must be returned with each subsequent re-submittal. S. The COB shall. attempt to complete each review of revised plans and specifications within fourteen (14) calendar days of receiving the revisions. A review comment letter may be mailed to the Engineer/Owner at the completion of each review, 6. All COB review comments must be adequately addressed and resolved before the final plans and specifications are approved by the City Engineer for construction. 7. The plans and specifications for water or sewer projects will not be considered for approval by the City Engineer without written approval of the final plans and specifications from the Superintendent of Water and Sewer or his designated representative. 8. Once all COB review comments have been adequately addressed and resolved the City Engineer must be supplied with four (4) complete sets of the final plans and specifications, signed and stamped by a Professional Engineer licensed in the State of Montana, and one half-size set of plans. Specification manuals are to be bound and contain the most current version of the revised documents and plan sheets are to be the most current version. The four (4) final fall-size sets and one 1/2 size set of plans and specifications submitted for City approval will be reviewed by the City Engineer to ensure that all requested modifications are included. An electronic version of the approved plans shall also be provided in either Autocad or PDF format, 9. For projects subject to Department of Environmental Quality (DEQ) review and approval, a copy of the project approval letter from DEQ must be submitted to the City Engineer prior to the preconstruction meeting. 1(l, The City Engineer will either approve or disapprove the submitted documents. An approval or disapproval letter will be sent to the Engineer/Owner, 11. Final stamped and approved plans and specifications will be distributed as follows: a. One set returned to the Engineer/Owner. b, One set and '/2 size set to the COB Water/Sewer Department. C, One set for the COB Engineering Department. d. One set for the COB Engineering Department Field Inspector. 12. No work is to begin on the project prior to obtaining the COB's and DEQ's written approval of the plans and specifications, and the completion of a preconstruction meeting conducted by the Owner's Engineer and attended by the Contractor(s) and COB representative(s). A "Pre-construction Meeting Checklist" will typically be included with the approval letter specifying additional documents which must be submitted prior to 5 scheduling a pre-construction meeting. B. Self-certification Process 1. Introduction/Intent A. Plans and specifications submitted using this process will not be reviewed in detail by the City Engineering Department. Fire service lines and domestic service lines are specifically excluded from this process. The City's existing review process will remain in place, and will be used unless the Submittal conforms with the self certification process and is accompanied by a completed self certification Checklist. B. The intention of this policy is that plans and specifications stamped and signed by a Professional Engineer registered in the State of Montana, submitted in confon-nance with this policy, and accompanied by the required checklists and certifications, will be acceptable to the City. C. The following are specifically excluded from the self-certification process: force mains, lift stations, booster stations, pressure reducing valves, and traffic signals. 2 Applicable Standards All infrastructure projects shall comply with the following design standards in order of precedence: A. COB Design Standards and Specifications Policy B. COB Modifications to Montana Public Works Standard Specifications (MPWSS) C. Bozeman Unified Development Ordinance D. DEQ Circulars I and 2 E. City Adopted MPWSS and Adopted Addenda The most recently adopted versions of the City Water and Wastewater Facilities Plans shall govern sewer and water trunk main design and sizing. The Storm Water Master Plan and Transportation Plan shall govern their respective service area issues. 3. Submittal Requirements Prior to submission of infrastructure plans and specifications, project approval (preliminary plat, Planned Unit Developments (PUD's), and in some cases Final Site Plans (FSP's)) from the City Commission must be obtained. The following shall be submitted to the City Engineering Department and approved by the Public Service Department (through the City Engineer): Prior to Plan and Specification Submittal; A. Water and Sewer Utilities Design Report as detailed in the project conditions of approval. Subsequent to receipt and approval of this report, the City will issue a water/sewer capacity letter if warranted. B. Pavement Design Report and Traffic Impact Analysis (if required), C. Storinwater Facilities Design Report. D. A schematic signage plan for the subdivision, noting any proposed traffic calming measures. With plans and specifications; E. Four (4) sets of plans and specifications (24" x 36" sheets only) stamped and signed by a P.E,, registered in the State of Montana, one '/2 size set of plans, and an electronic version of the plans in either Autocad or PDF format. F. A completed and signed COB Plan and Specification Checklist, G. Any easements which may be required. Easements must be properly executed. 4. City Review and Disposition A. Upon receipt of the plans and specifications and checklist, one complete set will be sent to the City Water/Sewer Superintendent and one set to the City Street Superintendent. B. Upon review and approval of the Checklist, Plans, and Specifications, the City Engineering Department will provide the engineer with a letter of approval and one set of plans and specifications stamped "Approved For One Year From This Date". C. Estimated time frames for City approval: With Deviations requested on City Checklist 2 weeks; this is a guideline only Without Deviations or with pre-approved variance I week D. No construction may begin prior to a pre-construction meeting which must be attended by the applicant's engineer, the contractor and the City. All preconstruction meeting requirements currently in place will remain in place. 7 E. Any changes to the approved plans must be reviewed and approved by the City Engineering Department and the Water/Sewer Superintendent. 5. Project Audits A. The intent of the self certification process is to place upon the design engineer the sole and significant burden and expectation that Public infrastructure plans and work completed within Bozeman fully comply with the City's infrastructure standards and requirements. The process necessitates a high degree of trust by the City and certainty by the design engineer that the plans and specifications fully meet the City's requirements. B. Deficiencies in plans which are discovered during project construction are inherently much more costly to the project schedule and budget than design deficiencies or issues resolved and addressed prior to construction. Subsequent to the City's approval of self certified plans and specifications, selected project plans will undergo audit review to assure compliance. Deficiencies discovered during the audit review or during construction may require revised plans to be submitted and approved, and may further require untimely and expensive correction or replacement of noncompliant work installed on the project. Project design self certification falsely or indiscriminately provided may be referred to the Montana Board of Professional Licensing. C. Project engineers with a history of design deficiencies or whose track record demonstrates repeated problems in their ability to design and complete projects adequately meeting the City's design standards will be more frequently audited, and may be prohibited from utilizing the self-certification process until adequate proficiency is demonstrated. As such, engineers are strongly encouraged to work closely with the City's engineering, field and operations staff throughout the pre-design, design and construction phases of a. project. Engineers without adequate experience with the City's design and infrastructure standards and who have not previous successfully completed infrastructure projects within the City are advised to utilize the City's full design review process in lieu of the self certification process. C. CONSTRUCTION COORDINATION 1. Pre-construction Meeting Following approval of infrastructure plans and specifications, the Engineer shall schedule a pre- construction meeting with the City of Bozeman, Contractor(s), and if applicable, other affected utilities or goverrimental. agencies. A "Preconstruction Meeting Checklist" will be included with the letter of approval which lists submittals that must be received by the City of Bozeman prior to scheduling a preconstruction meeting. 2. Shop/Fabrication Drawings Any required shop/fabrication drawings shall be submitted by the Contractor to the Engineer, 8 Upon approval, the Engineer shall submit four sets of the shop/fabrication drawings to the City Engineer a minimum of two days prior to the preconstruction meeting. 3. Bonding All new infrastructure that will be publicly maintained shall be bonded. Prior to initiation of construction, copies of the Contractor's Performance and Payment Bonds, each in an amount equal to 100% of the contract amount, in favor of the Owner, shall be filed with the Owner and the City of Bozeman. Prior to aggeptance of the publicly maintained infrastructure, the Contractor shall post a Maintenance Bond with the Owner equal to 20% of the actual cost of the improvements to correct any deficiencies in workmanship and/or materials which are found within the two-year warranty period. The City of Bozeman shall be named as a dual,oblige on the bond. The City of Bozeman ejpressly reserves the right to draft the Maintenance Bond for repairs, not cpMleted by the Property Owner, Developer, or Contractor within thirty calendar days of being advised that repairs are required. The Commencement Date for the Maintenance Bond shall be the date of acceptance by the City of Bozeman on the Certificate of Completion and Accotance. The Maintenance Bond shall remain in full force for the two-year period following this date, however if the expiration date of the Maintenance Bond falls after November 16, the expiration date of the Maintenance Bond shall be June 30 of the following 'Year. Maintenance Bonds may be in the form of a Surety Bond or a Certified Check. 4.

E. VERTICAL ALIGNMENT Design controls for vertical alignment are shown in Table IV-2. I. Permissible Roadwav Grades: The minimum allowable grade for any roadway or alley is one-half(0.5) percent. The maximum allowable grade for any roadway is shown in Table IV-2 of this Policy. The maximum grade for an alley is subject to the approval of the City Engineer. I Changing Grades- Continuous grade changes or "roller-coastering" shall not be permitted. The use of grade breaks, in lieu of vertical curves, is not encouraged, Where the algebraic difference in grade (A) exceeds one percent (1.0%), a vertical curve is to be used. 3, Vertical Curves: All vertical curves shall be symmetrical. Design criteria for vertical curves are found in,Table IV-2. The minimum grade within a sag (sump) vertical curve is five-tenths (0.50) of a percent. Minimum length of a vertical curve is shown in Table IV-2. All vertical curves shall be labeled, in the profile, with length of curve (L) and K (=L/A). 38 4. Intersections: The following additional criteria shall apply at intersections. a. The grade of the "through" street shall take precedence at intersections. At intersections of roadways with the same classification, the more important roadway, as determined by the COB Engineering Department, shall have this precedence. Warp side streets to match through streets, See Section IV.C. 3 above. b. The elevation at the point of tangency (PT) of the curb return on the through street is always set by the grade of the through street in conjunction with normal pavement cross slope. C. Carrying the crown of the side street into the intersecting through street is not permitted. d. At an arterial-arterial intersection, a more detailed review of the entire intersection's drive ability will be done. 5. Curb returns: Minimum fall around curb returns, when turning water, shall be three-tenths (0,3) of a foot for a fifteen (15) foot radius; four-tenths (0.4) of a foot for a twenty (20) foot radius; one-half(0.5) of a foot for a twenty-five (25) foot radius. For all other curb return radii use a grade of 1.25-percent within the return to establish minimum fall when turning water. The maximum fall around a curb return is 3.00-percent. Show and label high point location, elevation and intersection of flow line in plan view if applicable. 6. Connection with Existing Roadways: Connections with existing roadways shall be smooth transitions conforming to normal vertical curve criteria if the algebraic difference in grade (A)between the existing and proposed grade exceeds one percent (1.0%). When a vertical curve is used to make this transition, it shall be fully accomplished prior to the connection with the existing improvernent. Field-verified slope and elevation of existing roadways shall be shown on the plans. 7. Offsite Design and Construction: The design grade, and existing ground at that design grade, of all roadways that dead end due to project phasing, subdivision boundaries, etc., shall be continued in the same plan and profile as the proposed design for at least three hundred (300) feet or to its intersection with an arterial roadway. This limit shall be extended to six hundred (600) feet when arterial roadways are being designed. If the offsite roadway adjacent to the proposed development is not fully improved, the developer is responsible for the design and construction of a transition with a 4-foot road base shoulder for the safe conveyance of traffic from his improved section to the existing roadway. The following formula shall be applied to the taper or 39 land change necessary for this transition: Speed Limit 40 MPH or Less L =WS2/60 45 MPH or Greater L= WxS where L= length of transition in feet W= width of offset in feet S = speed limit or 85th percentile speed The City of Bozeman Engineering Department should be consulted for any -unusual transition conditions. Grade breaks greater than 1-percent are not allowed when matching existing dirt or gravel streets, 8. The cost of offsite pavement transitions shall be borne by the developer, F. MEDIAN TREATMENT Median curbs should be integral curb and gutter (with spill curb) unless otherwise approved.

Street Name Selection I A new street shall assume the name of the street on which it aligns unless the street does not and cannot in the future connect to an existing street segment along the alignment. 2. Duplication of street names will not be permitted. Proposed street names that have the same primary name of an existing street but a different suffix (e.g. Smith Drive and Smith Lane) are considered duplicates and will not be permitted. 3. Similar(text or phonetic) or confusing spelling of street names will not be permitted (e.g. Briar Lane/Brier Lane; Allen Lane/ Alan Lane; Beech Street/Peach Street). 4.

Street type designations should reflect the size and function of a street. Street types are contained in the suffix of the street name. I Approved street type descriptions and abbreviations are as follows: a) Avenue (AVE): a continuous street with a definite north-south directional course. b) Boulevard (BLVD): a wide arterial or collector type roadway, typically with a median. C) Circle (CIR): a street that intersects another street only once and terminates in a closed loop. d) Court (CT): a relatively short, uninterrupted dead-end street. e) Drive (DR): a curvilinear or winding street which continues through to other rights-of-way. f) Lane (LN): a minor roadway within a subdivision. g) Loop (LOOP): a relatively short, uninterrupted street that begins and ends on the same parent street at two different points, or a street that connects to two intersecting perpendicular streets. h) Parkway(PKWY), same as boulevard. i) Place (PL): a relatively short, uninterrupted dead-end street. j) Road (RD): an arterial or collector type roadway that may run in any direction. This street type designation should not be used for new streets in the City of Bozeman, unless the new street is an extension of an existing street designated as a road. k) Street (ST): a continuous street with a definite east-west directional course. Page 2 of 4 1) Way (WAY). a minor roadway within a subdivision. 3. Private roads should use the designations Place or Way. F. Cul-de-sacs and bubbles I When a cul-de-sac is located at the end of an existing street right-of-way or alignment, it shall be given the name of that street, including the suffix, whether the cul-de-sac is straight, curves, or meanders. 2. When two cul-de-sacs approach each other from opposite directions and are in the same alignment but do not join in any manner, they shall be assigned different street names. 3. Cul-de-sac or bubble streets less than 100 feet in length that provide frontage for three or fewer lots shall not be named,but shall take the name and numbering of the street adjoining. G. Addressing I Subdivision developers shall make arrangements with the Engineerm' Do.artment to assign addresses for all individual lots in the subdivision prior to filing of the final plat, A copy of the proposed final plat showing approved street names shall be submitted for use in assigning,addresses. Unless the proposed pEoJect has been designated for concurrent construction, the lot addresses will not be entered into the City address database until the final.,plat has been filed. 2. One street address number will be assigned for each separate building by the Engineering Department. For projects with multiple buildings on a single lot, a.,sile plan showing the proposed buildings shall be submitted to the Engineering Department for address assignment prior to site plan approval. Developers of multi-unit buildings shall, assign the unit or suite numbers. A floor plan showing the proposed unit or suite designations shall be submitted for UpLoval to the City Engineer's office prior to site plan or building permit approval. Unit/suite numbers shall be assigned based on the following guidelines: a) Multi-unit residential buildings (including,condominiums) o �separate lots: assign consecutive unit numbers (Unit 1, Unit'2, or unit letters (Unit A, Unit B, etc.) for each unit. b) Multi-unit residential buildings (including condominiums) on one lot: consecutive unit numbers for all the units in the Page 3 of 4 / development, beginning at the building closest to the nialill roadway entrance and continuing in a logical manner through all of the buildings (ie.: first buildim- 2301 Smith Street, Units 11.2, 3, 4; second buildinL,: 2305 Smith Street, Units 5, 6, 7, 8). Use a counter-clockwise circular sweep starting fi-om the rigjit side of the primary entryway as yo natically increment numbers throughout all buildings on the site so as to end at the left side of the sarne entryway, Avoid oscillating back and. forth across the site as inuch as possible. If the buildings have.,dwellin , g units on separate floors, use 3-digit numbers for all ofthe units, Nvith the first nuniber being the floor level. All building accesses shall clearly identify which Ullits are served by the access, C) MUlti--unit commercial buildiLigs:use 3-digit numbers for the units or suites, with the first number beine the floor level of the unit, d') Accessory dwelling units shall be assigned aseparate street number, however if there are no reinaining street numbers available, the main dwelligg unit on the property shall be designated unit A and the accessory dwelling unit sliall be designated Unit B.
