See Attached Development Engineering Memo dated x, 2017 Fire Authority: (Contact: Corey Thomas, 425-430-7024, cthomas@rentonwa.gov) 1 of 16 ADVISORY NOTES TO APPLICANT Page 2 of 6 LUA18-000490 1. Fire impact fees are applicable. Some examples are at the rate of $964.53 per multifamily units, for retail are $1.25 a square foot and for restaurant it is $5.92 a square foot. These fees are paid at time of building permit issuance. Credit will be granted for the removal of the existing buildings as long as current square footages and occupancy uses are provided. No charges or credits apply to parking garages. 2. The preliminary fire flow calculation is 4,000 gpm. A minimum of four fire hydrants are required. A minimum of one hydrant is required within 150-feet and three additional fire hydrants are required within 300-feet of all the buildings. Project shall meet maximum hydrant spacing of 300-feet on center also. Hydrants are required within 50-feet of all fire department connections for standpipes and sprinkler systems. Each sprinklered building shall have its own fire department connection. It is estimated that a minimum of a 12-inch looped fire main will be required around the entire site. A number of lengthy water main extensions are required in order to meet the probable fire flow requirements. Existing hydrants may be counted toward the requirements as long as they meet current code. 3. Approved fire sprinkler and fire alarm systems are required throughout all of the apartment buildings. Dry standpipes are required in all stairways. Direct outside access is required to the fire sprinkler riser rooms. Fire alarm systems are required to be fully addressable and full detection is required. Separate plans and permits required by the fire department. 4. Fire alarm and sprinkler systems are not required by code for most of the townhome buildings. Sprinkler systems are required in four of the townhome buildings due to limited fire apparatus access. Sprinkler systems may be needed as a design option in other townhome buildings if required fire flow needs cannot be met. 5. Fire department apparatus access roadways are required within 150-feet of all points on all buildings. Fire lane signage required for the on-site roadways. Required turning radius is 25-feet inside and 45- feet outside. Roadways shall be a minimum of 20-feet wide. Roadways shall support a minimum of a 30-ton vehicle and 75-psi point loading. Dead end roadways over 150-feet long require an approved turnaround. 6. All buildings that are required to be equipped with elevators, shall size the elevators to meet the requirements for a bariatric sized stretcher to accommodate all areas of each building. Car size shall be sized to meet a minimum of a 40-inch by 84-inch stretcher. 7. All areas of all apartment buildings shall comply with the City of Renton Emergency Radio Coverage ordinance. Testing shall verify both incoming and outgoing minimum emergency radio signal coverage. If inadequate, the building shall be enhanced with amplification equipment in order to meet minimum coverage. Separate plans and permits are required for any proposed amplification systems. Technical Services: (Contact: Amanda Askren, 425-430-7369, aaskren@rentonwa.gov) 1. There are numerous easements that encumber this property based on the title reports provided. As the project moves forward, releasing City interest in the easements will need to go through the City’s 2 of 16 ADVISORY NOTES TO APPLICANT Page 3 of 6 LUA18-000490 Release of Easement process to be approved by Council. Other easements with private interest will need to be extinguished through legal process. This process may need to be completed prior to construction permit issuance. 2. Based on the site plan, portions of right-of-way may need to be vacated. Please follow the City’s street vacation process to be approved by Council for the vacation. This process may need to be completed prior to construction permit issuance. 3. Due to the desire to phase the overall project, further discussion with City staff will be necessary to determine a plan of action for parcel and plat recording for the commercial and residential portions. 4. Street names and addressing for the properties will be assigned after preliminary plat approval. Community Services: (Contact: Leslie Betlach, 425-430-6619, lbetlach@rentonwa.gov) 1. Parks Impact fee per Ordinance 5670 applies. 2. The play area proposed as part of this plan, in its current configuration, has limited visibility with 3 sides closed in and is also located on the north side of a multi-story building. These conditions are not conducive to a children’s play area but would have limited impact for use of an off leash area which would keep this location activated (highly desirable). 3. If possible, incorporate another one or two smaller off leash areas as 673 units could include a number of pet owners. Police: (Contact: Cyndie Parks, 425-430-7521, cparks@rentonwa.gov) 594 Police Calls for Service Estimated (includes 151 townhomes, two large apartment buildings – 521 units total - and commercial space for retail). CONSTRUCTION PHASE 1. To protect materials and equipment it is recommended that all materials and tools be locked up when not in use. The site will need security lighting and any construction trailers should be completely fenced in with portable chain-link fencing. Fencing will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. 2. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2” throw when bolted. Glass windows in the trailer should be shatter-resistant. Any construction material that contains copper should be removed from the construction site at the end of each working day; housing this material at the site (even within a “secured” container) still holds a risk of it being stolen when the site is vacated at the end of the work day. Toolboxes and storage containers should be secured with heavy-duty shrouded padlocks and kept secured when not in use. There is a homeless population in this area that may be motivated to come to the site with the intention of making profit off of tools and materials. 3. I recommend the business post “No Trespassing” signs on the property while it’s under construction. This will aid police in making arrests on the property after hours. I strongly recommend the use of private security personnel to patrol the site during the hours of darkness due to the risk of this site 3 of 16 ADVISORY NOTES TO APPLICANT Page 4 of 6 LUA18-000490 being highly attractive to area thieves/burglars. Foregoing that, it’s recommended an interactive CCTV surveillance system be temporarily put into place to deter unwanted subjects from coming onto the job site. COMPLETED MIXED-USE BUILDINGS 1. All exterior doors should be made of solid metal with commercial-grade deadbolt locks with latch guards and/or pry-resistant cylinders around the locking hardware. Glass doors should be outfitted with hardware described above and equipped with a layer of security film. Security film can increase the strength of the glass, reducing the likelihood of suspects being able to shatter it in order to gain entry. 2. Access to the back of the retail areas appears to be unrestricted so it’s recommended security alarms be installed at these locations following construction. Submitted plans show a mix of retail/residential space (i.e., commercial/residential amenities space, Block B, Level 2), but at this writing it’s unclear as to what type of space will be shared. With that being said, defining public space from private will be important in these areas. Use of key fobs or access cards may be the best way to separate public traffic from private at these locations. 3. The installation of cameras within the internal hallways of the multi-housing structures is recommended. The proposed structures will be the largest multi-housing property in the city and are expected to incur one call, per unit, per year (on average). Having cameras installed in and throughout the property will assist in thwarting negative activity within typically isolated areas. 4. Any separate laundry facilities should be properly secured with doors that have sturdy deadbolts and latchguard. These locations can sometimes be tempting targets for thieves who want to break into the laundry appliances to collect the quarters that are accumulated there. That is why I recommend the installation of machines that run by prepaid cards only. It’s very expensive to fix these machines, only to have them broken into time-after-time due to the large amount of money that can be found inside of them. Limited Access Garage Locations & Parking Lots 1. The parking garages and parking lots will be a tempting target for thieves. Theft from motor vehicle and auto theft are prevalent and any garage housing vehicles utilized by visitors, employees, and /or residents are likely to have items of value left inside (electronic equipment, personal items, etc.). I recommend the installation, and substantial advertisement of, surveillance cameras inside and outside of any parking garage, an overabundance of lighting, and a noticeable presence of courtesy patrol. I assume there will be a large influx of unwanted ‘curiosity seekers’ brought into this particular area due to its location and commercial presence. 2. I recommend emergency call boxes be placed in each underground garage location in the event of an emergency. 3. Signage advising residents, guests, and retail customers to keep valuables out of their vehicles while 4 of 16 ADVISORY NOTES TO APPLICANT Page 5 of 6 LUA18-000490 parked should be posted in all parking areas (to include the limited access garages). Courtyard / Landscaping Areas The current plans to provide a “park feel” will more than likely attract a homeless population, possibly pushing out the intended usership for these locations. I discourage the installation of long benches, solid surface tables, or “rest stops” that can be easily accessed by the public. Any retaining walls, concrete berms, or easily-accessible wall placements be finished with material that would discourage long-term loitering (grated designs, skateboard deterrents, varied levels, etc.). Lighting Lighting is the #1 deterrent to crime and with a development of this size, it will be especially important due to the large amount of vehicle and pedestrian traffic that will be pulled into the location. This will assist in the deterrent of theft from motor vehicle (one of the most common crimes in the country) as well as provide safe pedestrian travel for both employees, customers and residents. Disposal Receptacles All dumpster areas should be housed within a structure of a height and strength that will deter unwanted subjects from gaining access to them when not in use. Due to the location of this development, I assume it will experience an ongoing population of transients at the location and having easy access to trash receptacles will motivate them to remain in the area. Open Common Areas Due to the heavy foot and vehicle traffic in the area it won’t be long before the property experiences unwanted subjects utilizing the common areas in and around Solera. It will be important for residents, homeowners and business owners work in corroboration to keep these areas hospitable for the intended usership. This would include keeping the common areas clean of debris and garbage, that any graffiti be reported and covered up immediately, and that any suspicious activity be reported to police as soon as possible. Storage Units Although it may seem low-risk, it’s actually quite common for multi-housing properties to experience storage room thefts. I recommend placement of these units been in a high traffic residential area, within a structure that has a deadbolt with 3” wood screws installed in the strikeplate, as well as the installation of latch guards to help protect the locking mechanism from being pried. Maintenance Rooms Any maintenance or utility rooms should have deadbolts with 3” wood screws installed in the strikeplate, with latch guards installed (where applicable) to help protect the locking mechanisms from being pried. Notes It’s important that an emergency access code (or access fobs) be available to law enforcement so they can respond to emergency situations. It should be noted that this can come in the form of an emergency call box that unlocks main entry doors or a knox box that contains access fobs inside. This type of access is a separate accommodation from what is provided for the fire department. 5 of 16 ADVISORY NOTES TO APPLICANT Page 6 of 6 LUA18-000490 If there are plans for fitness centers, recreation rooms, or meeting facilities within the multi-housing buildings, care should be taken if these rooms will be housing flat screen TVs, projector or computer equipment. It’s common for these types of items to be stolen, so I recommend access to these locations be by resident fob or access card only so subjects coming into these locations can be tracked in the event of a burglary. Townhomes Buildings 1. Each townhome should have solid core pedestrian doors, preferably metal or solid wood, with peepholes.The doors should have heavy-duty deadbolt locks with a minimum 1-½” throw and installed with 3” wood screws. Any external storage areas should also have solid wood or metal doors, with deadbolts and latch guards installed. 2. Sliding windows and glass patio doors should have secondary locks installed to restrict movement. Simply placing a sturdy, fitted dowel into the tracks may be adequate. 3. Alarm systems are recommended for each residential unit. Any stairways should be constructed of lattice, wood or metal railing so visibility is open and unobstructed. 4. Security lighting should be installed along sidewalks, in stairways, foyers, and pathways. Each home should have individual addresses clearly posted with numbers at least 6” in height and of a color contrasting with the color of the building. Addresses should be illuminated so they are easily located. This will assist emergency personnel in locating the correct location for response. 5. Any resident storage should have latch guards and deadbolts installed. Dumpster locations should be secured within their own housing and well lit. If possible, creating a dumpster location that can be secured for resident’s use, but accessible for waste management, is recommended. 6. Landscaping should be installed with the objective of allowing visibility: not too dense or too high. Too much landscaping will make residents feel isolated, and will provide criminals with concealment to commit crimes such as burglary and vandalism. It’s recommended the developer have a Renton Police Crime Prevention Representative conduct a security survey of the premises once construction is complete. This will allow for a more comprehensive security evaluation that would be specific to each structure. Contact Cyndie Parks, 425.430.7521, when you would like to make an appointment.

During the weekday AM peak hour, the project would generate approximately 1 net new trips with approximately 3 inbound and 1 outbound trips. During the weekday PM peak hour, the project would generate approximately net new trips with an additional inbound and fewer outbound trips. Weekday AM and PM peak hour trip generation for the proposed development was estimated based on the land use size and trip rates from the Institute of Transportation Engineers’ (ITE) Trip Generation Manual (10th Edition, 2017) for Multifamily Housing (Mid-Rise) (LU #221), Senior Adult Housing – Attached (LU #252), Shopping Center (LU #820), and Day Care Center (LU #565) land uses. The ITE Shopping Center (LU #820) land use was used to estimate the trip generation for the existing uses. The proposed project trip generation was adjusted for pass-by and internal trips to account for the localized nature of the commercial uses. Pass-by trips reflect traffic already on streets in the vicinity of the project site that would visit the commercial components of the project while driving by the site on the way to its final destination. Based on ITE Trip Generation Handbook (2017 3rd Edition), the pass-by rates for the retail uses is 34 percent. Internal trips were calculated based on the method presented in the Trip Generation Handbook. g.
