Washington Ave. Emmett, Idaho 83617 E. Applicant's Statement/Justification: Please see applicant's narrative for this information. V. PROCESS FACTS A. The subject application is for a development agreement modification and preliminary plat. Except for the development agreement modification request, which only requires City Council review, a public hearing is required before the Planning & Zoning Commission and City Council on this matter, consistent with Meridian City Code Title 11, Chapter 5. B. Newspaper notifications published on: January 4 and 18, 2016 C. Radius notices mailed to properties within 300 feet on: December 21, 2015 D. Applicant posted notice on site(s) on: January 11, 2016 1i�� r/:�►111I. A. Existing Land Use(s) and Zoning: The subject property consists of two rural residential properties, zoned RUT in Ada County. B. Character of Surrounding Area and Adjacent Land Use and Zoning: 1. North: Rural residential property, zoned RUT in Ada County; rural residential property currently in the development process (Shelburne Subdivision), zoned R-4; and residential properties in Napoli Subdivision, zoned R-2 2. East: Agricultural property owned by the school district, zoned RUT in Ada County; and an assisted living facility (Diamond View), zoned R-8 3. South: E. Amity Road and agricultural property, zoned R-8 4. West: S. Eagle Road and rural residential/agricultural property, zoned RUT in Ada County C. History of Previous Actions: The subject property was previously platted as Lots 1 and 3, Block 1, Martinel Subdivision and recently annexed (AZ-14-016) with an R-4 zoning district with the requirement of a development agreement (DA). The DA is scheduled for City Council approval on January 19, 2016, which will finalize the annexation. A preliminary plat (PP-14-018) for Nesting Swan Ranch Subdivision was proposed with the annexation but was denied by City Council on July 7, 2015. Note: The proposed preliminary plat is deemed to not be in substantially the same form as the previous preliminary plat that was denied. Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 2 D. Utilities: 1. Sanitary sewer mains to provide service to the proposed development currently exist near the southwest corner of the Napoli Subdivision. 2. Location of water: Water mains intended to provide service to the proposed development currently exist in E. Amity Road and S. Eagle Road. 3. Issues or concerns: Applicant shall be required to connect their interior water mains with the existing water main in S. Eagle Road, and stub a water main to the east boundary for future extension. E. Physical Features: 1. Canals/Ditches Irrigation: There are some irrigation ditches that run along the property lines of the site. 2. Hazards: Staff is not aware of any hazards that exist on this property. 4. Flood Plain: This site does not lie within the Meridian Floodplain Overlay District. VII. COMPREHENSIVE PLAN POLICIES AND GOALS Land Use: The subject property is designated Medium Density Residential (MDR) on the Future Land Use Map (FLUM) contained in the Comprehensive Plan. MDR designated areas allow smaller lots for residential purposes within City limits. Uses may include single-family homes at gross densities of 3 to 8 dwelling units per acre (d.u./acre). The applicant proposes to subdivide and develop the 21.8 acre site with 68 new single-family residential building lots and 2 lots for the existing homes at a gross density of 3.21 d.u./acre with a net density of 4.25 d.u./acre. The proposed gross density is within but at the low end of the desired density range of 3 to 8 d.u./acre in MDR designated areas. Policies: Staff finds the following Comprehensive Plan policies to be applicable to this application and apply to the proposed use of this property (staff analysis in italics): • "Support a variety of residential categories (low-, medium-, medium -high and high -density single-family, multi -family, townhouses, duplexes, apartments, condominiums, etc.) for the purpose of providing the City with a range of affordable housing opportunities." (3.07.01E) The proposed medium density single-family residential development should contribute to the variety of residential uses that exist in this area which currently consist of rural, low and medium residential densities, a residential care facility and agricultural uses. • "Require new urban density subdivisions which abut or are proximal to existing low density residential land uses to provide landscaped screening or transitional densities with larger, more comparable lot sizes to buffer the interface between urban level densities and rural residential densities." (3.05.02F). The proposed plat does not provide a transition in density to the rural Taylor or Luke parcels; all of the proposed lots are approximately 8,000 sf. Both of these parcels are designated on the FLUM for medium density residential uses and will likely redevelop in the future with similar lot sizes and density. The lots proposed along the north boundary transition to those approved in Shelburne Subdivision which are slightly larger lots (10,000- I1,000+/- s f.) and are also separated by a 30 foot wide common lot. Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 3 • "Require pedestrian access connectors in all new development to link subdivisions together to promote neighborhood connectivity as part of a community pathway system." (3.03.03B) A pedestrian pathway is proposed on the plat to the adjacent property to the east where a school is planned. A pathway connection is also proposed to the sidewalk along S. Eagle Road at the northwest corner of the southern portion of the site. A pedestrian pathway is also proposed within the common area at the north boundary of the site that will also provide a connection to the future school site and Shelburne Subdivision to the north. • "Require street connections between subdivisions at regular intervals to enhance connectivity and better traffic flow." (3.03.03C) The proposed plat depicts a stub street (S. Martinel Avenue) to the north for future extension and interconnectivity with Shelburne Subdivision; to the south at the southwest corner of the site to the Luke property (Parcel #SI128336250); and public street frontage to the Taylor property (Parcel #R547570020) and Diamond View assisted living facility (Parcel #S1128336506). • "Require new residential development to meet development standards regarding landscaping, signage, fences and walls, etc." (3.05.02C) Street buffer landscaping is required along S. Eagle Road and E. Amity Road, both arterial streets, in accord with the standards listed in UDC 11-3B-7C. Six-foot tall vinyl privacy fencing is proposed around the perimeter of the site as depicted on the landscape plan and should comply with the standards listed in UDC 11-3A-7. Separate permits shall be obtained for signage and fencing. • "Protect existing residential properties from incompatible land use development on adjacent parcels." (3.06.01F) The proposed residential development should be compatible with adjacent existing rural and low density residential uses and the residential care facility to the east. Further, because the adjacent properties are also designated on the FLUM for future MDR uses, the proposed development should be consistent with future development in this area. • "Require common area in all subdivisions." (3.07.02F) The proposed development is required to provide a minimum of 10% (or 2.18 acres) qualified open space in accord with the requirements listed in UDCII -3G-3. • "Evaluate the comprehensive impact of growth in all land use decisions (e.g., traffic impacts, school enrollment and parks etc.)." (3.01.01B) A letter was received by the City from the West Ada School District detailing how the proposed development will affect the school district; they anticipate a total of 56 school aged children within this development. The letter states that the school district is currently operating at or over capacity and students living in the proposed development cannot be assured of attending the neighborhood school and may need to be bussed to available classrooms across the district. The district requests the developer provide safe walkways, bike paths, and safe pedestrian access for students. (See letter in the public record for more information). ACHD reviewed the subject project; draft comments/conditions are provided in Exhibit B. The Park's Department had no concerns regarding this development. Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 4 • "Permit new development only where urban services can be reasonably provided at the time of final approval and development is contiguous to the City." (3.01.0117) City services are available and will be extended by the developer upon development of the site in accord with UDC I1-3A-21. Analysis: For the reasons listed above, Staff deems the proposed density and development is consistent with the MDR designation and goals and policies of the Comprehensive Plan. VIII. UNIFIED DEVELOPMENT CODE (UDC) A. Purpose Statement of Zone: Per UDC 11-2A-1, the purpose of the residential districts is to provide for a range of housing opportunities consistent with the Meridian comprehensive plan. Residential districts are distinguished by the allowable density of dwelling units per acre and corresponding housing types that can be accommodated within the density range. The medium low -density residential (R-4) district allows a maximum gross density of 4 dwelling units per acre. B. Schedule of Use: Unified Development Code (UDC) Table 11-2A-2 lists the principal permitted (P), accessory (A), conditional (C), and prohibited (-) uses in the R-4 zoning district. Any use not explicitly listed, or listed as a prohibited use is prohibited. The proposed use of the site for single- family detached dwellings is a principal permitted use in the R-4 zoning district. C. Dimensional Standards: Development of the site should be consistent with the dimensional standards listed in UDC Tables 11-2A-5 for the R-4 zoning district. D. Landscaping: Street buffer landscaping shall be installed in accordance with the standards listed in UDC Table 11-2A-5 for the R-4 zoning district. E. Off -Street Parking: Off-street parking is required in accord with UDC Table 11-3C-6 for single- family dwellings. IX. ANALYSIS A. Analysis of Facts Leading to Staff Recommendation: 1. Development Agreement Modification (MDA): The applicant requests a modification to the development agreement (MDA) required with AZ-14-016 to reflect a modified site layout, building elevations and updated provisions based on the proposed preliminary plat. The conceptual development plan included in the development agreement (DA) depicts a total of 63 building lots (see Exhibit A.2). The preliminary plat associated with the conceptual plan was denied by City Council. The developer has changed since the previous application and has submitted a new preliminary plat with a substantially different layout. The proposed plat consists of 70 building lots, including 2 lots for the existing homes, for an overall gross density of 3.21 dwelling units per acre consistent with the MDR FLUM designation as discussed above in Section VII. Staff has included analysis below on the proposed preliminary plat and building elevations and recommends approval of the proposed MDA with modifications to the text of the DA as shown in Exhibit A.3 based on the new layout. 1. Preliminary Plat (PP): The proposed plat is a re -subdivision of Lots 1 and 3, Block 1, Martinel Subdivision and consists of 70 single-family residential building lots (including 2 lots for existing homes) and 18 common lots on 21.76 acres of land in an R-4 zoning district. The Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 5 applicant submitted a phasing plan, included in Exhibit A.4, which depicts 5 phases of development starting at the north end of the site. The overall gross density for the subdivision is 3.21 d.u./acre with a net density of 4.25 d.u./acre. The average lot size in the proposed development is 10,239 square feet. Note: There is a 1.17 acre out parcel at the southwest corner of this site (Parcel No. S1128336250, Luke property). Staff has verified that it is an original parcel of record as defined in UDC 11-IA-1 and therefore, is not required to be included in the subject preliminary plat application. Dimensional Standards: Development of this site is required to comply with the dimensional standards listed in UDC Table 11-2A-5 for the R-4 district and UDC 11-2A-3. I revised plat was submitted today that addressed the lots that were below the 60" of frontage Staff has reviewed the proposed plat and found the street frontage of several lots to be below the minimum street frontage required of 60 feet; these lots should be revised accordingly except for those lots with street frontage on cul-de-sacs or at approximately a 90 degree angle which may have a minimum frontage of 30 feet per UDC 11-2A-3. All of the lots meet the minimum size of 8,000 square feet (s.f.) except for L6?W MI&A ' §91"41101YO&Ycted as an open space lot. This lot is actually intended to provide access to the back of Lot 19, Block 2, the Morgan property. If not a common lot, it's required to be a minimum of 8,000 s.f. Existing Structures: The existing homes owned by the Allen's and Morgan's are proposed to remain on lots in the proposed subdivision (Lot 4, Block 3 and Lot 19, Block 2 respectively). The Morgan's have an accessory structure that exists across proposed Lots 25-26, Block 2 that does not comply with the setback requirements of the R-4 district. Therefore, the structure should either be removed prior to recordation of the final plat phase which contains the structure; or, the land that contains the structure may be incorporated into Lot 19, Block 2 with the existing home. If incorporated into Lot 19, Block 2, the lot should not have street frontage on two streets that create a "through" lot. The Allen's also have an accessory structure that encroaches within proposed Lots 8 and 9, Block 3. Prior to recordation of the final plat phase that contains the Allen home (Lot 4, Block 3), the accessory structure shall be removed as it does not comply with the setback requirements of the R-4 district; or, the structure may be reduced in size to comply with the setback requirements. The structure may remain if incorporated into Lot 4, Block 3 with the existing home; however, the lot shall not have street frontage on two streets that create a "through" lot. All of this encroachments will be dealt with prior to final plat of the phase that contains those lots Block Length: The plat is required to comply with the block length standards listed in UDC 11- 6C-3F. Staff has reviewed the proposed plat and found it to be in compliance with the aforementioned standard. Access: There is one public street access (S. Martinel Avenue, classified as a local street) proposed for this development via E. Amity Road; no access is proposed via S. Eagle Road. All internal streets within the proposed subdivision are public. Direct lot access via S. Eagle Road and E. Amity Road is prohibited. S. Martinel Lane currently exists as a private road easement in favor of Lots 1 and 3, Block 1 of Martinel Subdivision and is depicted on the recorded plat for Martinel Subdivision. Because this street is proposed to be improved as a public street, the easement should be vacated. The Martinel Subdivision plat also depicts a common access easement to Eagle Road on Lots 1 and 2 (see plat note #8); the portion of the easement that lies on Lot 1 should be vacated. �II f his ease entts will be c ted a art of he final platt[n roces tu� treets:. stub street( art ne� venue) is proposed a� i e north boundary of the plat for future extension and interconnectivity with Shelburne Subdivision, currently in the development Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 6 process to the north. Public street frontage is provided to the Taylor property (Parcel #R5475470020); the Diamond View Assisted Living property (Parcel #S 1128336506) and to the Luke property (Parcel #S 1128336250). A temporary turnaround easement is depicted at the end of S. Palatino Avenue on Lots 2 and 3, Block 4. ACHD recommends the turnaround be located on one buildable lot, instead of two and that this lot be encumbered by a temporarym currenioyloar gent p odeitifi�ilsoturn a lat o om not in favor of buildable lot until the street is extended. non build but vyill a ree.to c I��tions f a ro al from ACHD Common Driveways: All common driveways proposed on me site s�iall comp�y wpi tie standards listed in UDC 11-6C-3D. The common driveway serving Lots 6 and 7, Block 4 should be located within a common lot so that pedestrians accessing the pro ossoia�eenaC�tanges in the to the sidewalk along Eagle Road aren't trespassing on private property. Sidewalks: A minimum 5-foot wide detached sidewalk is required to be constructe3sa�oigUbmitted Eagle Road and E. Amity Road, per UDC 11-3A-17 and as required by ACHD. Attached sidewalks are proposed internally within the subdivision. Pathways: All pathways are required to be constructed in accord with the standards listed in UDC 11-3A-8 and the adjacent common area landscaped in accord with the standards listed in UDC 11-3B-12C. The Pathways Master Plan does not depict a regional pathway on this site. A micro -path connection is proposed at the east boundary and a pathway is proposed along the north boundary to the future school site to the east for neighborhood connectivity. A pathway connection is also proposed on the common lot line between Lots 6 and 7, Block 4; the pathway and 20-foot wide sewer easement depicted on the plat should be included in a 30-foot wide common lot. Landscaping: A landscape plan was submitted with this application for the area proposed to be platted as shown in Exhibit A.5. A 25-foot wide street buffer is required along S. Eagle Road and E. Amity Road, both arterial streets, per UDC Table 11-2A-6; a 30-foot wide buffer is proposed. Landscaping within the street buffers is required to comply with the standards listed in UDC 11-3B-7C. The buffer was changed to 25" Landscaping within the common areas is required in accord with the standards listed in UDC 11- 3G-3E as proposed. The unimproved street right-of-way along S. Eagle and E. Amity Roads is greater than 10 feet from the edge of pavement to edge of sidewalk; this area is required to have a 10-foot wide compacted gravel shoulder meeting ACHD's construction standards and should be landscaped with lawn or other vegetative groundcover in accord with UDC 11-3B-7C.5. The landscape plan should be revised to reflect compliance with this requirement. A 30-foot wide common area planted with grass is proposed along the northern boundary of the subdivision where a sewer and water easement is proposed; a pedestrian pathway is included in this area for access the future school site to the east. Staff has reviewed the landscape plan for compliance with the landscaping standards listed in UDC 11-3B and found the plan to be in general compliance with these standards except as noted in this section and in Exhibit B. Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 7 Tree Mitigation: The applicant has met with Elroy Huff, City Arborist, to confirm mitigation requirements for this site. A total of 70 caliper inches of existing healthy trees are proposed to be removed; mitigation information is included on the landscape plan in accord with UDC 11-313- 1 OC. Open Space: A minimum of 10% qualified open space is required to be provided for this development in accord with UDC 11-3G-3A.1. Based on the area of the preliminary plat (21.8 acres), a minimum of 2.18 acres of qualified open space is required to be provided as set forth in UDC 11-3G-3B. The applicant proposes a total of 2.35 acres (or 10.78%) of qualified open space but did not provide details on how that calculation was reached. According to Staff's calculations, only 1.97 acres (or 9%) of qualified open space is proposed consisting of/z the street buffers along S. Eagle and E. Amity Roads; the large open grassy area on Lot 33 Block 1; the linear common area with the pathway along the north boundary of the site on Lot 26, Block 1 and Lot 1, Block 2; and the common area with a pathway connection to the ff east on Lot 12, Block 2. Staff recommends the applicant provide a miniMum ov 2.� p�a anc�landscape qualified open space as set forth in UDC 11-3G-3B with the final plat. Site Amenities: All developments consisting of five acres of more are require( to prowv sde abmitted to the city minimum of one site amenity; one additional site amenity is required for ea€ !NiI i%rqu* i4sopen space per UDC 11-3G-3A.2, in accord with the standards listed in UDC 11-3G-3C. Based on the area of the preliminary plat (21.8 acres), a minimum of one amenity is required to be provided. The applicant proposes to provide a playground within Lot 33, Block 1 as an amenity. Staff recommends the applicant submit a detail of the proposed playground equipment with the final plat application. I agree to this condition Utilities: Street lighting is required to be installed within the development in accord with the City's adopted standards, specifications and ordinances. All development is required to connect to the City water and sewer system unless otherwise approved by the City Engineer in accord with UDC 11-3A-21. A 20-foot wide sewer easement is depicted on the plat on the common lot line between Lots 6 and 7, Block 4. This easement should be included within a 30-foot wide common lot. Done Note: There are several existing utility easements that are depicted on the recorded plat for Martinel Subdivision. If any of these easements are no longer needed, they may be vacated through the public hearing process which requires approval by City Council. Pressurized Irrigation (PI): An underground PI system is required to be provided to each lot in the subdivision as proposed in accord with UDC 11-3A-15. The applicant's letter states PI will be coordinated with the New York Irrigation District and Boise Project Board of Control. Storm Drainage: A storm drainage system is required for the development in accord with the City's adopted standards, specifications and ordinances. Design and construction shall follow best management practice as adopted by the City in accord with UDC 11-3A-18. Waterways: An irrigation ditch runs along the west property line on the northern portion of the site. All irrigation ditches are required to be piped or otherwise covered in accord with UDC 11- 3A-6A. request exception Floodplain: This site does not lie within the Meridian Floodplain Overlay District. Existing Structure(s): There are two existing homes that are proposed to remain on lots (Lot 19, Block 2 and Lot 4, Block 3) in the proposed subdivision. These structures comply with the setback requirements of the R-4 zoning district. Logan Creek Subdivision — MDA, PP H-2015-0037 PAGE 8 Building Elevations: The applicant has submitted pictures of typical sample building elevations for future homes in this development, included in Exhibit A.6. Building materials appear to consist primarily of stucco with stone accents, and horizontal and vertical siding. Future development should be generally consistent with these elevations and construction materials. Because homes on lots that back up to S. Eagle Road and E. Amity Road will be highly visible, staff recommends the rear of structures on lots that face these streets incorporate articulation through changes in materials, color, modulation, and architectural elements (horizontal and vertical) to break up monotonous wall planes and roof lines. This requirement is already included in the development agreement. Fencing: All fencing should comply with the standards listed in UDC 11-3A-6B and 11-3A-7. A 6-foot tall vinyl privacy fence is proposed to be constructed by the developer around the perimeter of the subdivision as shown on the landscape plan. A 6-foot tall wrought iron fence is proposed adjacent to large common open space lot on Lot 33, Block 1 and adjacent to the common areas that contain a pathway. A temporary 6-foot tall vinyl fence is depicted on the landscape plan adjacent to the existing Morgan house at the edge of the right-of-way along E. Mount Etna Street and S. Martinel Avenue. This fence does not comply with the setback requirements listed in UDC 11-3A-7C and should be removed or relocated in accord with UDC standards prior to City En neer signature on the final plat for that phase of development. A revised fencing plan wi�be submitted prior to final platting In summary, Staff recommends approval of the proposed MDA and PP applications for this site with the recommended changes to the DA in Exhibit A.3 and conditions listed in Exhibit B of this report in accord with the findings contained in Exhibit C.

SUBJECT: Nesting Swan Ranch Service Analysis Background The Nesting Swan Ranch development has been proposed near the intersection of Eagle Road and Amity Road. The proposed development is spread over two trunk sheds that have been master planned to be served by two different trunk lines. The City requested that J-U-B review serviceability options for the development and downstream capacity to determine if the trunk shed boundary can be modified. The proposed service is through an 8-inch collector in the Napoli Subdivision immediately to the north. After an initial check of the City s sewer model, a more detailed analysis was warranted. The City's sewer model was designed and built to model trunk lines 10-inches and larger in size. Collector lines (8-inch) are included in the model to help improve flow routing and attenuation of flow injections into the larger trunk lines, but not to specifically analyze fl- inch sewers. Most of the collector lines are modeled at assumed minimum slopes, not actual inverts. The City is currently collecting rim and inverts for the collectors, but the effort is still incomplete. The following analysis uses the City's current sewer model and Master Plan as the base and provides the further detail required to accurately analyze the subject 8-inch collector. II. Capacity Analysis The proposed development is shown in yellow on Figure 1. It is located in master plan service area A and B. The portion of the development that falls in service area A is master planned to discharge to a future 12-inch trunk line west of Eagle Road. The portion of the development that falls In service area B is master planned to discharge into the existing 15-inch trunk line in Eagle Road. However, Diamond View Assisted Living is also located in service area A and it is served to the North through the Napoli Subdivision. The extension of 8-inch sewer to Diamond View Assisted Living provides potential service to service area C through the Napoli Subdivision as well. The proposed development would like to be served by the 8-inch line in the Napoli Subdivision. a 250 South Beechwood Avenue Suite 201, Boise, ID 83709 p 208-376-7330 f 208-323-9336 w www.jub.com -4- No Text Page 2 pipe v Ah iiipRkog +� Nal off Sutxtir-loon --5-� / Proposed Connection Point proposed Development l_- 1 tt i J i Potential ; School Site QR1fty Rd Diamond View Assisted Living t FIGURE 1 — NESTING SWAN DEVELOPMENT Record drawings were reviewed for the 8-inch line in the Napoli Subdivision and the fl- inch between the Napoli Subdivision and Diamond View Assisted Living. The controlling pipe section is an 8-inch pipe with a slope of 0.35% located in the Napoli Subdivision in South Palatino Avenue (PipelD = Q18-49-Q18-48-0). Three scenarios were evaluated, as described below, to determine the serviceability of the 8-inch collector in Palatino Avenue. • Scenario 1 o Service through 8-inch collector in Palatino Ave —All of service area B, service area A east of Eagle Road including Diamond View Assisted Living. • Scenario 2 o Service through 8-inch collector in Palatino Ave —AII of service area B, service area A east of Eagle Road including Diamond View Assisted Living and service area C (assuming a school comprises about 38 acres). • Scenario 3 o Service through 8-inch collector in Palatino Ave — All of service area B, service area A east of Eagle Road including Diamond View Assisted Living and service area C (assuming master plan residential densities for the potential school site). www.jub.com -6- J-U-B ENGINEERS, Inc Page 3 Three additional scenarios utilizing the 15-inch trunk in Eagle Road were evaluated as well. • Scenario 4 o Service through 8-inch collector in Palatino Ave — Eastern portion of service area B (the proposed development), service area A east of Eagle Road including Diamond View Assisted Living and service area C (assuming a school comprises about 38 acres). o Service through 15-inch trunk in Eagle Rd — Western portion of service area B outside the proposed development. • Scenario 5 o Service through 8-inch collector in Palatino Ave — Eastern portion of service area B (the proposed development), Diamond View Assisted Living and service area C (assuming a school comprises about 38 acres). o Service through 15-inch trunk in Eagle Rd — Western portion of service area B outside the proposed development and the southern portion of the proposed development in service area A. • Scenario 6 o Service through 8-inch collector in Palatino Ave —Diamond View Assisted Living and service area C (assuming a school comprises about 38 acres). o Service through 15-inch trunk in Eagle Rd —All of service area B and the southern portion of the proposed development in service area A. Land use types used in the Master Plan followed the current comprehensive plan at the time it was developed. Specific changes to land use can alter the flows generated. The Master Plan includes safety factors to allow for normal variations in density, but when multiple and significant increases are concentrated to an area served by a collector that was not modeled in detail (8-inch), it may result in localized capacity issues. The Master Plan land use north Amity Road and east of Eagle Road is Medium Density Residential with a density of 5.5 du/ac and a unit flow of 170 gal/du. The rest of service area C south of Amity Road is Low Density Residential with a density of 3.0 du/ac and a unit flow of 214 gal/du. Scenario 2 includes a school which was modeled at 110 gpad. Additional assumptions used for this analysis include: • Residential Peaking Factor 4 2.0 • School Peaking Factor 4 2.5 • Infiltration _> 75 (GPAD) The remaining capacity in the limiting reach in Palatino Avenue is shown in Table 1. www.jub.com -7- J-U-B ENGINEERS, Inc Page 4 TABLE 1 - REMAINING CAPACITY IN EXISTING 8-INCH LINE I i Design Pipe (') !

(3) Design pipe capacity and remaining capacity are based on a d/D of 0.50 for 8-inch lines. (4) Full pipe capacity and remaining capacity are based on a d/D of 1.00 for 84nch lines. The estimated build out peak flow exceeds the design capacity of the 8-inch in Palatino Avenue line for scenarios 2, 3 and 4. The design capacity for an 8-inch line is defined by a depth over diameter of 0.50 in accordance with the 2010 Sewer Master Plan. A depth over diameter of 0.50 in an 8-inch line results in a safety factor of 2.00 for peak flows. This d/D is used to allow for uncertainties in actual versus planned land use (such as the school and density variations) and changes in service area boundary (such as this analysis request). All scenarios considered for this analysis show sufficient capacity when full pipe flow is considered. Scenario 3 has the least remaining capacity of 0.11 mgd which corresponds to a depth over diameter of 0.62 and results in a safety factor of 1.40 for peak flows. Ill. Summary Generally, it is most prudent to allow for a design depth over diameter of 0.50 for 8-inch collection sewers. However, existing pipes are allowed to flow at the full pipe condition in accordance with the 2010 Sewer Master Plan. The 8-inch line in Palatino Avenue has sufficient capacity if full pipe flow is allowed, but the safety factor on the peak flows is estimated to be reduced from 2.00 to 1.40 at full build out of scenario 3. The safety factor would be reduced from 2.00 to 1.75 if the area built out according to scenario 2 with a school being built. In order to maintain a safety factor of 2.00 for the limiting reach in Palatino Avenue, some of the area to the east of Eagle Road needs to be served by the 15-inch trunk line in Eagle Road such as in Scenarios 5 and 6.

Alternatively, part or all of service area C could be served through a new sewer extension off of the 12-inch line in Zaldia Lane that ends at manhole Q18-55. If the area is allowed to develop according to Scenarios 2-4, development of service area C should be monitored to determine if any of the future development in that service area has high water and sewer usage that could further reduce the safety factor on peak flows. www.jub.com - 10- J-U-B ENGINEERS, Inc- B.
