Sacramento Bee reporter Ryan Lillis and I discussed a number of city issues including the City Hall credit card scandal and the McKinley Park fire with host Beth Ruyak on Capital Public Radio’s “Insight” program Tuesday.

The show began with Ruyak asking Lillis about Lisa Serna-Mayorga, an aide to Mayor Kevin Johnson who resigned after an alleged $9,000 were put on her city credit card for personal issues, including a trip to Disneyland.

An investigation has been launched, and the city is looking at its policies for credit cards. Lillis will chat with The Sacramento Press on Wednesday at noon. To view that chat, click here for the Sac Press Live link.

Ruyak and I discussed the aftermath of Saturday morning’s devastating playground fire in McKinley Park in East Sacramento. Authorities suspect it was the work of an arsonist, and after the initial anger and sadness, the community is working to get the funds together for rebuilding the structure.

Another topic Ruyak and I discussed was the Launch 2012 Music, Design and Fashion show that took place last week.

From its beginnings with a number of musicians playing to complement snippets from silent films to a mid-week architectural exhibit in Midtown and the music festival on Saturday featuring DJ Shadow and Chromeo, organizer Clay Nutting said he thought the event was a success, and while there were a few hiccups – he said the event proved that Sacramento can support a large-scale arts event, and he looks forward to next year’s event.

The half-cent sales tax proposal on the November ballot was another topic Ruyak covered with Lillis, who pointed out that voters are becoming more receptive to the idea of small sales tax increases, but he expects that more organized opposition to it will surface before November.

In other city news, the medical marijuana debate is continuing. I talked about some of the City Council’s proposed changes to smaller details of the city’s medical marijuana ordinance – including possible changes to where some dispensaries can be located. Another issue the city will address is whether to ban open-air home growing of medical marijuana. Lillis said the issue has been debated at length, and he foresees much more debate before it’s done with.
