General Required Findings: Private streets may be permitted when the Council finds that the private street is in compliance with each of the following standards. a. Provides safe and effective movement of both vehicular and pedestrian traffic; b. Does not adversely affects access or good public transportation planning to adjacent property and to the area travel networks; c. Does not land lock adjacent property due to topography or parcel layout; d. Does not restrict public access to places of public attraction, use or interest; e. Does not connect one public street to another, encouraging travel through the development; or, f. Use or alignment of the private street does not interfere with the continuity of public streets. 2. Allowed Uses for Private Streets: a. Single Family/Townhouse/Duplex Residential Private streets may be permitted when, in the Commission s and Council s opinion, the parcel shape or site topography will not allow street design to meet District width standards or in the cases in which conformance to District requirements is in conflict with the intent of minimizing disruption to vegetation as defined in the Hillside and Foothill Areas Development Ordinance. 4. Private Street Classification and Requirements a. Single Family/Townhouse/Two Family Private Residential Street Standards shall be according to the following table: Single Family/Townhouse/Two Family Private Residential Street Standards Number of Minimum Street Width Sidewalk Sidewalk Sidewalk Residential Lots vs. R/W Width Back of Curb to Required Required Easement Street Length (feet) Back of Curb for Both four (4) foot Allowed
13 of 25 (feet) Sides One Side Up to 3 lots w/length less than 200 feet 24 24 No Yes Yes* Up to 3 lots w/length 28 (24 for the 28/24 No Yes Yes* greater than 200 feet final 200 feet) 4 to 10 lots w/length less than 200 feet 24 24 Yes No Yes* 4 to 10 lots w/length 28 (24 for the 28/24 Yes No No greater than 200 feet final 200 feet) 11 or more lots 40 28 Yes No No The applicant has requested a Waiver of Subdivision Ordinance 9-20-07.E.4.a, which requires that a private street that serves more than 10 lots have a right-of-way width of 40 feet, a street width (back of curb to back of curb) of 28 feet and a four foot wide sidewalk located on both sides of a private street (within the right-of-way). The applicant is proposing to construct the private street with a 30 foot wide right-of-way, a 29 foot wide street section and a four foot wide sidewalk on both sides of the proposed private street (within an easement). Staff supports the waiver request due to the narrowness of the subject property. As such, staff recommends approval of the Waiver of Subdivision Ordinance to allow the construction of a private street with a right-of-way width of 37 feet and four foot wide sidewalks located in an easement on both sides of the proposed private street.

Chapter 6 deals specifically with transportation related issues. Objective 6.1.3 encourages the completion of the existing street system and the creation of new links within the community. Objective 6.1.4 promotes land use policies that limit access as necessary to maintain a safe and efficient street system while allowing reasonable access to individual development parcels. To achieve these objectives, Policy 6.1.3.5 requires new developments to provide stub streets to adjacent, undeveloped parcels, Policy 6.1.4.4 discourages access to arterial streets, and Policy 6.1.4.8 encourages methods such as cross-access agreements, backage roads, and other means to reduce access points onto arterials. Policy 8.1.18.1, specific to the planning area in which the site is located indicates that State Street shall be developed as a limited-access transit corridor with transit-supportive land uses. An emphasis on the use of frontage roads and local street connections is also encouraged. The project furthers each of these elements. One existing access point to State Street will be eliminated, and a public street connection will be provided to undeveloped ground east and west of the site. This will allow these properties to develop without additional access points to State, and will help in completing the network of streets and sidewalks in the vicinity of the site. Goal 7.1 encourages the development of an adequate supply of safe, sanitary housing at price and rent levels appropriate to the varied financial capabilities of City residents, and to provide for diversity in type, density and location of housing with special emphasis on maintaining neighborhood stability. Objective 8.1.6 indicates that residential land-uses shall be designated to provide a variety of housing densities, product types and affordable
15 of 25 costs, and shall be located and distributed in a manner that is compatible with adjacent uses and promotes transit and pedestrian activity. This project includes a housing product that will add to the variety already present in the neighborhood, and will promote pedestrian activity as it is within walking distance of existing commercial facilities and a designated transit route. Objective 7.1.1 establishes the need for additional attached single-family dwellings to accommodate the needs of a growing population. This project will provide 10 such units in a manner that is compatible to surrounding development. Building Section Marlene Southard The existing structure must be demolished or removed prior to the City Engineer signing the Final Plat. Permits are required and can be obtained by contacting the Planning & Development Services Department Permit Desk at 384-3802. Sediment and Erosion Control Steve Webb An erosion and sediment control plan (ESC) conforming to the requirements B.C.C.

Fire Department access roads and fire lanes shall have a minimum outside turning radius of 48' with an inside radius of 28'. Any dead-end road in excess of 150' needs a Fire Department approved turnaround. No grade may exceed 10% (please note that fire apparatus are designed for a maximum 6% grade). Dead end roads are prohibited from exceeding 700 feet. Width and turning radius measurements specified by this paragraph can include those surfaces vehicles generally drive upon. Specifically, gutter and rolled curb are generally considered useable, while vertical curb or sidewalks are not. Specific Requirement: For streets having a width less than 36 feet back of curb to back of curb parking shall be restricted on (1) one side; for streets having a width less than 29 feet back of curb to back of curb parking shall be restricted on both sides; and for standard ACHD cul-de-sacs parking shall be restricted on both sides. A note on the face of the Final Plat is required noting the parking restriction prior to signing of the Final Plat by the Boise City Engineer. In addition, No Parking signs shall be installed in accordance with the requirements of the IFC. Specific Condition: Streets must be marked accordingly. Specific Requirement: Maximum hydrant spacing for this project is 500 feet between hydrants. Specific Condition: Hydrants shown on the Preliminary Plat appear to be adequate. However, we reserve the right to modify requirements as more information comes to light. Variables affecting hydrant numbers and location include, but are not limited to, area, construction type, existing hydrants, accuracy of information provided in the application, strategic location for fire fighting forces, and required fire flow. New hydrants must be "non-private" installations. General Requirement: Fire Department required fire hydrants, access, and street identification shall be installed prior to construction or storage of combustible materials on site. Provisions may be made for temporary access and identification measures. Specific building construction requirements of the International Building Code, International Fire Code, and Boise City Code will apply. However, these provisions are best addressed by a licensed Architect at building permit application. Boise City Parks Department Cheyne Weston No comments received.
17 of 25 Boise Airport Matt Petaja No comments received. Ada County Highway District Andrew Mentzer, April 24, 2007 The above noted site has been previously reviewed with the following applications: SUB06-00091 / CUP06-00118. In response to your request for comment, ACHD has the following revisions to the original Staff action: Sufficient right-of-way exists for State Street, abutting the site. The required sidewalk should be constructed 2 feet off of the right-of-way line along State Street (measured back of walk to right-of-way / property line). With the development of the adjacent parcels to the east and west, ACHD will require the proposed public street (N. Belem Avenue) to be extended in order to reduce access points to State Street. Eventually, connections may be made to N. Hacienda Avenue to the northeast and N. Carlsbad Way to the west; per the following policy: District policy 7203.5.1 states that the street design in a proposed development shall cause no undue hardship to adjoining property. An adequate and convenient access to adjoining property for use in future development may be required. If a street ends at the development boundary, it shall meet the requirements of sub section 7205, noncontinuous streets. District policy 7205.5 states that stub streets will be required to provide intra-neighborhood circulation or to provide access to adjoining properties. Stub street swill conform with the requirements described in Section 7204.5, 7204.6 and 7204.7, except a temporary cul-de-sac will not be required if the stub street has a length no greater than 150 feet. A sign shall be installed at the terminus of the stub street stating that, TIS ROAD WILL BE EXTENDED IN THE FUTURE. All other requirements noted in the original Staff action are to be upheld.

19 of 25 B. Findings for Consideration 1. West State Street Right-of-Way Policy: District policy requires between 114-feet and 120-feet of right-of-way for 7-lane principal arterial roadways (Figure 72-F1B). This right-of-way allows for the construction of a 7-lane roadway with curb, gutter and 5-foot concrete detached sidewalks. District Sidewalk Policy: District policy requires 7-foot wide attached (or 5-foot detached) concrete sidewalk on all collector roadways and arterial roadways (7204.7.2). Applicant Proposal: The applicant does not propose additional improvements or right-of-way for West State Street. Staff Comment/Recommendation: There is sufficient right-of-way abutting the site for the future widening of State Street to a 7-lane facility. The applicant is required to construct sidewalk not closer than 53-feet (measured face of walk to centerline). 2. North Belem Avenue District Street Section and Right-of-Way Policy: Commercial Use District policy 7202.8 and 72-F1A, requires roadways abutting commercial developments to be constructed as a 40-foot street section with curb, gutter and 5-foot concrete sidewalk within 54-feet of right-of-way. District Street Section and Right-of-Way Policy: Residential Use District policy 7204.4.2 states, developments with any buildable lot that is less that 1- acre in size will typically provide streets having a minimum pavement width of 32-feet with curb, gutter and sidewalks. The total street width shall be 36-feet from back-of-curb to back-of-curb. Variations of this width may be allowed, depending on traffic volumes forecast to be generated by the development. Concrete sidewalks shall be a minimum of 5-feet in width unless they are separated from the curb 5-feet or more in which case the sidewalk shall be a minimum of 4-feet in width. District Offset Policy: District policy 7204.11.6, requires local roadways to align or offset a minimum of 300- feet from an arterial roadway (measured centerline to centerline). Applicant Proposal: The applicant has proposed a public entry road intersecting State Street approximately 25-feet west of the southeast property line. The applicant has proposed the entry road as a 36-foot street section with curb, gutter and sidewalk within 50-feet of right-of-way at the west property line. The proposed location offsets another existing local roadway,
20 of 25 Carlsbad Way, by approximately 270-feet (measured centerline to centerline). The applicant has proposed one commercial lot take access from the 36-foot street section. The applicant has proposed to locate right-of-way abutting the eastern property line for approximately 175-feet (measured from the southeastern property line, north) Staff Comment/Recommendation: The subject site has frontage on only one public roadway, State Street. The applicant has redesigned the subject site to locate the entry road as far away from Carlsbad Way as possible and has provided a possibility for eastern connectivity by providing right-of-way along the eastern property line: therefore, the applicant is granted a modification of District Roadway Offset Policy, staff is supportive of the applicant s proposal for the public road intersecting State Street, which is approved with this application as proposed. The subject site is only 150-feet wide and the applicant only proposed one commercial lot to take access to the 36-foot street section and not State Street. The applicant proposes a private street north of the easterly right-of-way that abuts the property line and only one residential lot fronts the proposed public roadway. The applicant is granted a modification of District Street Section Policy because no residential lots are proposed on the eastern side of the entry road adjacent to the commercial lot and on the basis that the commercial traffic would not likely impact the residential use to the north of the subject site. 3. Private Streets District Private Street Policy: District policy 7205.6, other jurisdictions in Ada County establish the requirements for private streets. The District retains authority and will review the proposed intersection of a private and public street for compliance with District intersection policies and standards. Access Policy: District policy 7207.8 states that direct access to arterials and collectors is normally restricted. The developer shall try to use combined access points. If the developer can show that the use of a combined access point to a collector or arterial street is impractical, the District may consider direct access points. Access points for proposed developments at intersections should be located as far from the intersection as practical, and in no case closer than as illustrated on Figure 72-F4, unless a waiver for the access point has been approved by the District Commission. District Offset Policy: District policy 7204.11.6, requires local roadways to align or offset a minimum of 125- feet from another local roadway (measured centerline to centerline). Applicant Proposal: The applicant has proposed to construct a 20-foot wide private road intersecting Belem Avenue approximately 160-feet north of the south property line.
21 of 25 Staff Comment/Recommendation: Staff is supportive of the applicant s proposal for the private street accessing North Belem Avenue. If the City of Boise approves the private road, the applicant shall be required to pave the private roadway a minimum of 20 to 24-feet wide and at least 30-feet into the site beyond the edge of pavement of North Belem Avenue. The applicant should provide a plan showing how the private road grade meets the public road. Street name and stop signs are required for the private road. The signs may be ordered through the District. Verification of the correct, approved name of the road is required. ACHD does not make any assurances that the private road, which is a part of this application, will be accepted as a public road if such a request is made in the future. Substantial redesign and reconstruction costs may be necessary in order to qualify this road for public ownership and maintenance. The following requirements must be met if the applicant wishes to dedicate the roadway to ACHD: a. Dedicate a minimum of 50-feet of right-of-way for the road. b. Construct the roadway to the minimum ACHD requirements. c. Construct a stub street to the surrounding parcels. 4. Knuckles, Islands and Turnarounds District Turnaround Policy: District policy 7205.2.1 requires turnarounds to be constructed to provide a minimum turning radius of 45-feet. The applicant should also be required to provide a minimum of a 29-foot street section on either side of any proposed center islands within the turnarounds. The medians should be constructed a minimum of 4-feet wide to total a minimum of a 100-square foot area. Applicant Proposal: The applicant has not proposed any turnaround at the terminus of the public roadway. Staff Comment/Recommendation: The applicant is required to provide an easement to the public for a portion of the private road to include the entire frontage of Lot 16 and continuing to encompass the entire knuckle, south to the public right-of-way. 5. District Tree Planters District s Tree Planter Width Policy prohibits all trees in planters less than 6-feet in width. In addition to prohibiting trees in planters less than 6-feet in width, the policy requires a minimum planter width of 6-feet for class II tress with the installation of root barriers on both sides of the planter strip or a minimum planter width of 8-feet without
22 of 25 the installation of a root barrier. The policy also requires Class I and Class III trees to provide a minimum planter width of 10-feet. 6.

STORMWATER MANAGEMENT RECOMMENDATIONS It is recommended that storm water be pre-treated prior to discharge to the subsurface to prevent impact to ground water and surface water quality. The engineers and architects involved with the design of this project should obtain current best management practices for stormwater disposal and design a stormwater management system that is preventing groundwater and surface water degradation. Manuals that could be used for guidance are: 1) Stormwater Best Management Practices Guidebook Prepared by the Boise City Public Works Department, May 2000. 2) State of Idaho Catalog of Stormwater Best Management Practices for Idaho Cities and Counties Prepared by the Idaho Division of Environmental Quality, July 1997.
