Tax Lot 44 is currently a single parcel zoned as RII (single family) in Tier M. Based on our review ofthe documents submitted with your proposal and on the discussions in the technical conference, the following are the general Public Works Department's infrastructure requirements for your proposed development. Please be aware that the project is subject to the requirements of Chapter 18.12 Short Subdivisions of the Port Townsend Municipal Code and the state subdivision act and is subject to review under the city's ESA ordinance (Chapter 19.05 PTMC). The requirements described below could be modified through preliminary plat approval or ESA permitting process to assure compliance with the PTMC and the state subdivision act. Where not inconsistent with - Chapters 18.12 and 19.05 of the PTMC, the requirements described below are valid for one year from the date of this letter unless changes are made to the proposed development, in which case our requirements related to those changes may be modified. Except where noted, the following requirements address Public Works issues -only. No determination of acceptability of your proposal from a Planning or Building Department standpoint is provided. The Planning Department makes the final determination regarding preliminary and final plat requirements and compliance with the ESA ordinance. Streets - The existing property, Tax 44, abuts. Thomas- Street, 25th Street and Hastings AveWe. The proposed Lots A, B, C, and D abut 25th Street, while the large lot E includes an existing residence that takes its access from Thomas Street. Chapter 18.1 -2 requires that all short plats must conform to the city's engineering design standards and improvements must be installed as a condition of final plat. Creation of the four lots fronting along existing platted 25th Street winch is a local access street meets the engineering design standard requirement for a grid or modified grid street network (Chapter 6, Section 8). 25th Street is-an. existing unmaint-ained, substandard Molotski Technical Conference May 27, 1999 Page 2 of 4 gravel local access street with approximately a 30 foot right- of-way. The design standard for local access. streets is 16 feet of pavement plus concrete curb and gutter (Detail T -9) and a minimum 50 foot right -of -way. Thomas Street is also an existing substandard gravel street with a 30 -foot right -of -way. It will function as a minor collector in the future given the potential build -. out of the area and therefore Detail T-7 would apply to, Thomas Street. As a condition of the short plat, 20 feet of right -of -way along the frontage of lots A, B, C and D must be dedicated to the city. In-addition, 25th Street from Thomas Street to and through proposed lot D must be upgraded and paved with a section per Detail T -2. Curb and gutter are required on both sides of the street along-Lots -A; B, C. and D. The city will pay for the cast of the materials for paving the street section from Thomas Street to Lot A, that is, the street section not directly fronting the subject property. Since there is an existing residence on Thomas Street, the actual design for the street is undefined and the existing right-of-way is narrow, there will be no improvements required on Thomas Street as a condition of the short plat. However., since your development adds traffic to this street and since the street does not. meet the City's current design standards, a No- Protest Agreement to formation of an LID will be required. This agreement waives the rights of the property owner to protest the formation of a Local Improvement District for upgrading the street, providing sidewalks and bicycle lanes, frontage improvements and adding storm drainage facilities. No- Protest Agreements are valid for a period of 10 years. To meet the requirements of the city's- Non - Motorized Plan, a trail easement dedicated to the city is required as shown on the drawing submitted with your application. The trail easement needs to be extended along the east side of lot D to connect to 25th Street. The exact location of the trail easement on Lot E would be defined during the preliminary plat approval process. Since 25th Street is also designated as a neighborhood connector and since sidewalks and pathways are required for new subdivisions, a 5 foot sidewalk with planting strip is required along the 251h. Street frontage. The shared driveway access shown on your site plan is encouraged in our engineering design standards. Sewer - There is an existing sewer main in 25th Street that may be used for service to Lots A, B, C and D Separate side sewer connections are required for each structure. Existing Lot E will remain on a septic system. Water - There is an existing .water main in 25th Street that may be used for service to-your proposed Lots A, B, C, and D. A double water service connection may be installed for service to every two lots. a Molotski Technical Conference May 27, 1999 Page 3 of 4 Fire H drant - In accordance with the city's Engineering Design Standards, fire hydrants. must be located within 250 feet ofresidential property. There is an existing fire hydrant at the corner of Rosecrans and 25th and also one at 25th between Thomas and Logan. No additional hydrants are required. Please be aware that these are orange top hydrants that provide less than 1000 gpm. Stormwater - Stormwater pipe and catch basins must be included as part of the street improvements and must extend from a catch basin at Thomas Street to the end of street improvements. The ditch on the north side of 25th Street after Lot D must also be improved to handle flows from the street. As per the street improvements, the city will provide the materials . for the stormwater system from Thomas Street to Lot A for installation by your contractor. For the proposed Lots A, B, C and D, a stormwater plan-must be prepared as part of the preliminary plat to define how stormwater will be handled for the new impervious surface created by the residences on the lots. As we discussed at the technical conference there are several options which could be considered depending on the type of soils on site. Options could include infiltration, detention or utilizing drainage facilities on Lot E. Temporary Erosion and Sediment Control - Temporary erosion and sediment control (TESC) measures must be in place at the time of initial site excavation and must be maintained throughout project construction in order to prevent sediment from leaving the construction site. The public works inspector is available to work with you on any specific requirements for your site. Public Works Permits - A Street & Utility Development Permit is required for the work described above and for all work in the City's right -of -way. The permit application along with final design drawings and an improvement method report is submitted following preliminary plat approval. All work described above must be designed by licensed civil engineer in conformance with the City's Engineering Design Standards and must be inspected by the public works inspector. Final construction and sign-offby the public works inspector and submittal of record drawings is required prior to final plat approval or, alternatively, a bond or cash escrow may be furnished per PTMC 18.12.090. Fees - The Street and Utility Development Permit fee is $250 plus a $70 minimum fee for inspection services. The permit and inspection fees allow for 6 hours of permit review and 2 hours of inspection. Additional review and inspection time will be billed at an hourly rate of $50 and $3 5, respectively. It is likely on a project of this scale that additional hourly fees may apply. The City has a process for review of waiver and variance requests from Public Works standards. Such requests must be submitted in writing to the Director of Public Work and must describe how the waiver and variance criteria as provided in Port Townsend Municipal Code Sections 12.04.160, or 12.04.170 (waiver and variance from street improvements), and/or 13.01.130 or a Molotski Technical Conference May 27, 1999 Page 4 of 4 Th „ QXj F u -r L _ ti y r AN, x r F IIr t l yam.. 6. ,-' I 4(` L. #' @' 1'. 1 S 'a i.,r r l - .
